What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 2 of its 11 active ingredients.
  • “Triphala, Powder” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
  • “Greenselect Phytosome” is listed as a grouped ingredient — the label gives one combined amount (150 mg) without saying how much of each component you get.
  • “Traditional Ayurvedic Blend” is a proprietary blend — the label gives one combined amount (300 mg) without saying how much of each component you get.

Veda Lean contains 11 ingredients, including 11 active components. The most prominent are green tea leaf extract (providing antioxidant and fat-metabolism support), chromium (a mineral involved in blood sugar regulation), amla or Indian gooseberry (a traditional Ayurvedic fruit rich in vitamin C), cinnamon bark extract, fenugreek seed extract, and guggul extract—all common in Ayurvedic wellness formulas.

The product also includes phosphatidylserine (a compound that supports cognitive function) and Bacillus subtilis DE111, a probiotic strain. Triphala is a traditional three-fruit blend (containing chebulic myrobalan, belleric myrobalan, and another component) used in Ayurvedic practice.

The inactive ingredients—rice husk, hypromellose, sunflower lecithin, maltodextrin, and silica—serve as capsule materials and flow agents.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Ayurvedic support for weight management.
  • We looked for evidence on: Dyslipidemia, Hypercholesterolemia, Cognitive function, Diabetes, Metabolic health, Body composition — and 1 related terms.
  • The strongest evidence on file: Fenugreek is rated "Possibly Effective" for Diabetes (Natural Medicines).
  • Also on file: Indian Gooseberry is rated "Possibly Effective" for Dyslipidemia.
  • Also on file: Chromium is rated "Possibly Effective" for Diabetes.

Green tea leaf extract in this product is rated likely effective for human papillomavirus (HPV) prevention and possibly effective for ovarian cancer and high cholesterol (hyperlipidemia). Chromium is likely effective for chromium deficiency and possibly effective for diabetes, though it's rated possibly ineffective for prediabetes.

Amla (Indian gooseberry) is rated possibly effective for acid reflux (GERD) and high cholesterol (dyslipidemia). Cinnamon bark extract, fenugreek seed extract, and guggul extract all have insufficient evidence for most of their traditional uses listed in the data we hold—meaning the science hasn't established clear benefit for those conditions yet.

Phosphatidylserine is possibly effective for age-related cognitive decline and Alzheimer disease. Bacillus subtilis is rated possibly effective for antibiotic-associated diarrhea.

The product's overall effectiveness depends on which health goal you're targeting, and you should discuss expectations with your pharmacist or doctor.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 8 of the 9 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 9 of 9.
  • General safety write-ups exist for 9 of 9.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Green tea leaf extract is generally well tolerated in moderate amounts, though concentrated extracts at high doses have been linked to rare liver injury. Most common side effects from green tea are mild digestive ones—bloating, constipation, diarrhea, nausea—and occur more often at higher doses.

Rare serious effects include liver damage and blood disorders. Caffeine in green tea passes into breast milk and can affect a nursing infant, so high-dose supplements should be avoided during breastfeeding; food amounts are generally fine.

During pregnancy, moderate tea is likely acceptable, but high-dose extracts should be limited. Chromium is generally well tolerated at typical supplement doses, though high or long-term doses may carry risks; gastrointestinal irritation, headaches, insomnia, and mood changes are the most common side effects, with rare reports of kidney or liver damage.

Amla is well tolerated as a food but has less safety research at supplement doses; safety during breastfeeding is too limited to recommend it. Cinnamon bark extract is generally safe at food amounts; high supplement doses carry a concern for liver damage over time because of its coumarin content, and it should be avoided at medicinal doses during pregnancy.

Fenugreek is generally well tolerated but can cause abdominal pain, bloating, diarrhea, nausea, and rare severe allergic reactions including anaphylaxis; it may affect the uterus and should be avoided at medicinal doses during pregnancy. Guggul commonly causes digestive upset (belching, bloating, diarrhea, nausea) and dose-dependent skin reactions (rash, itching), and should be avoided during pregnancy and breastfeeding.

Phosphatidylserine is generally well tolerated but may cause flatulence, nausea, headache, insomnia, and gastrointestinal upset; safety during pregnancy and breastfeeding is not established. Bacillus subtilis is generally well tolerated in healthy adults, though quality varies by product; safety in pregnancy and breastfeeding is limited.

Green Tea Leaf Extract58 drug types · 1,293 drugs

Atorvastatin (Lipitor)

Green tea extract seems to reduce the levels and clinical effects of atorvastatin.
In healthy humans, taking green tea extract 300 mg or 600 mg along with atorvastatin reduces plasma levels of atorvastatin by approximately 24%. The elimination of atorvastatin is not affected. Atorvastatin is a substrate of organic anion-transporting polypeptides (OATPs). Research shows that two of the major catechins found in green tea, epicatechin gallate (ECG) and epigallocatechin gallate (EGCG), inhibit OATPs. Some OATPs are expressed in the small intestine and are responsible for the uptake of drugs and other compounds, which may have resulted in reduced plasma levels of atorvastatin. It is not clear if drinking green tea alters the absorption of atorvastatin.

Likelihood Likely Evidence B
Ephedrine

Theoretically, concomitant use might increase the risk for stimulant adverse effects.
Green tea contains caffeine. There is evidence that using ephedrine with caffeine might increase the risk of serious life-threatening or debilitating adverse effects such as hypertension, myocardial infarction, stroke, seizures, and death.

Likelihood Probable Evidence D
Nadolol (Corgard)

Green tea seems to reduce the levels and clinical effects of nadolol.
Preliminary clinical research shows that green tea consumption reduces plasma concentrations of nadolol. Compared to a control group, both peak levels and total drug exposure (AUC) of nadolol were reduced by approximately 85% in subjects who drank green tea daily for two weeks. Drinking green tea with nadolol also significantly reduced nadolol's systolic blood pressure lowering effect. Other clinical research shows that a single dose of green tea can affect plasma nadolol levels for at least one hour. Green tea catechins have been shown to inhibit organic anion transporting polypeptides (OATP), one of which, OATP1A2, is involved in the uptake of nadolol in the intestine The interaction is thought to be due primarily to the epigallocatechin gallate (EGCG) content of green tea.

Likelihood Likely Evidence B
5-Fluorouracil

Theoretically, high doses of green tea might increase the effects and side effects of 5-fluorouracil.
Animal research shows that taking green tea in amounts equivalent to about 6 cups daily in humans for 4 weeks prior to receiving a single injection of 5-fluorouracil increases the maximum plasma levels of 5-fluorouracil by about 2.5-fold and the area under the curve by 425%.

Likelihood Possible Evidence D
Adenosine (Adenocard)

Theoretically, green tea might decrease the vasodilatory effects of adenosine and interfere with its use prior to stress testing.
Green tea contains caffeine. Caffeine is a competitive inhibitor of adenosine at the cellular level. However, caffeine doesn't seem to affect supplemental adenosine because high interstitial levels of adenosine overcome the antagonistic effects of caffeine. It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests. However, methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing.

Likelihood Possible Evidence B
Anticoagulant/Antiplatelet Drugs

Theoretically, green tea may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Conflicting reports exist regarding the effect of green tea on bleeding risk when used with anticoagulant or antiplatelet drugs; however, most evidence suggests that drinking green tea in moderate amounts is unlikely to cause a significant interaction. Green tea contains small amounts of vitamin K, approximately 7 mcg per cup. Some case reports have associated the antagonism of warfarin with the vitamin K content of green tea. However, these reports are rare, and very large doses of green tea (about 8-16 cups daily) appear to be needed to cause these effects. Furthermore, the catechins and caffeine in green tea are reported to have antiplatelet activity.

Likelihood Unlikely Evidence D
Beta-Adrenergic Agonists

Green tea contains caffeine. Theoretically, concomitant use of large amounts of caffeine might increase cardiac inotropic effects of beta-agonists.

Likelihood Probable Evidence D
Bortezomib (Velcade)

Theoretically, green tea might interfere with the effects of bortezomib.
In vitro research shows that green tea polyphenols, such as epigallocatechin gallate (EGCG), interact with bortezomib and block its proteasome inhibitory action. This prevents the induction of cell death in multiple myeloma or glioblastoma cancer cell lines. Advise patients taking bortezomib, not to take green tea.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, green tea might reduce the effects of carbamazepine and increase the risk for convulsions.
Green tea contains caffeine. Animal research suggests that taking caffeine can lower the anticonvulsant effects of carbamazepine and can induce seizures when taken in doses above 400 mg/kg. Human research has shown that taking caffeine 300 mg in three divided doses along with carbamazepine 200 mg reduces the bioavailability of carbamazepine by 32% and prolongs the plasma half-life of carbamazepine 2-fold in healthy individuals.

Likelihood Possible Evidence D
Celiprolol (Celicard)

Theoretically, green tea might reduce the levels and clinical effects of celiprolol.
In a small human study, taking green tea daily for 4 days appears to decrease blood and urine levels of celiprolol by at least 98%. This interaction is possibly due to the inhibition of organic anion transporting polypeptide (OATP). Green tea catechins have been shown to inhibit organic anion transporting polypeptides (OATP), one of which, OATP1A2, is found in the intestine The interaction is thought to be due primarily to the epigallocatechin gallate (EGCG) content of green tea.

Likelihood Possible Evidence D
Cimetidine (Tagamet)

Theoretically, concomitant use might increase the effects and adverse effects of caffeine in green tea.
Green tea contains caffeine. Cimetidine can reduce caffeine clearance by 31% to 42%.

Likelihood Likely Evidence B
Clozapine (Clozaril)

Theoretically, green tea might increase the levels and adverse effects of clozapine and acutely exacerbate psychotic symptoms.
Animal research suggests that, although green tea extract does not affect the elimination of clozapine, it delays the time to reach peak concentration and reduces the peak plasma levels. Also, concomitant administration of green tea and clozapine might theoretically cause acute exacerbation of psychotic symptoms due to the caffeine in green tea. Caffeine can increase the effects and toxicity of clozapine. Caffeine doses of 400-1000 mg daily inhibit clozapine metabolism. Clozapine is metabolized by cytochrome P450 1A2 (CYP1A2). Researchers speculate that caffeine might inhibit CYP1A2. However, there is no reliable evidence that caffeine affects CYP1A2. There is also speculation that genetic factors might make some patients be more sensitive to the interaction between clozapine and caffeine.

Likelihood Possible Evidence B
Contraceptive Drugs

Theoretically, concomitant use might increase the effects and adverse effects of caffeine found in green tea.
Green tea contains caffeine. Oral contraceptives can decrease caffeine clearance by 40% to 65%.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Inhibitors

Theoretically, concomitant use might increase the levels and adverse effects of caffeine.
Green tea contains caffeine. Caffeine is metabolized by cytochrome P450 1A2 (CYP1A2),. Theoretically, drugs that inhibit CYP1A2 may decrease the clearance rate of caffeine from green tea and increase caffeine levels.

Likelihood Possible Evidence D
Dipyridamole (Persantine)

Theoretically, green tea might decrease the vasodilatory effects of dipyridamole and interfere with its use prior to stress testing.
Green tea contains caffeine. Caffeine might inhibit dipyridamole-induced vasodilation. It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests. Methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing.

Likelihood Probable Evidence B
Disulfiram (Antabuse)

Theoretically, disulfiram might increase the risk of adverse effects from caffeine.
In human research, disulfiram decreases the clearance and increases the half-life of caffeine.

Likelihood Probable Evidence B
Diuretic Drugs

Theoretically, using green tea with diuretic drugs might increase the risk of hypokalemia.
Green tea contains caffeine. In excessive amounts, caffeine can reduce potassium levels due to stimulation of the sodium-potassium pump. Diuretics can also cause lower potassium levels.

Likelihood Possible Evidence D
Estrogens

Theoretically, estrogens might increase the levels and adverse effects of caffeine.
Green tea contains caffeine. Estrogen inhibits caffeine metabolism.

Likelihood Probable Evidence B
Ethosuximide (Zarontin)

Theoretically, green tea might reduce the effects of ethosuximide and increase the risk for convulsions.
Green tea contains caffeine. Animal research suggests that caffeine 92.4 mg/kg can decrease the anticonvulsant activity of ethosuximide. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Felbamate (Felbatol)

Theoretically, green tea might reduce the effects of felbamate and increase the risk for convulsions.
Green tea contains caffeine. Animal research suggests that a high dose of caffeine 161.7 mg/kg can decreases the anticonvulsant activity of felbamate. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Fexofenadine (Allegra)

Green tea can decrease blood levels of fexofenadine.
Clinical research shows that green tea can significantly decrease blood levels and excretion of fexofenadine. Taking green tea extract with a dose of fexofenadine decreased bioavailability of fexofenadine by about 30%. In vitro, green tea inhibits the cellular accumulation of fexofenadine by inhibiting the organic anion transporting polypeptide (OATP) drug transporter. Research shows that two of the major catechins found in green tea, epicatechin gallate (ECG) and epigallocatechin gallate (EGCG), inhibit OATPs, specifically OATP1A2, OATP1B1, and OATP2B1. In addition, green tea has been shown to reduce the absorption of some drugs that are OATP substrates.

Likelihood Probable Evidence B
Flutamide (Eulexin)

Theoretically, green tea might increase the levels and adverse effects of flutamide.
Green tea contains caffeine. In vitro evidence suggests that caffeine can inhibit the metabolism of flutamide. Theoretically, concomitant use of caffeine and flutamide might increase serum concentrations of flutamide and increase the risk adverse effects.

Likelihood Possible Evidence D
Fluvoxamine (Luvox)

Theoretically, fluvoxamine might increase the levels and adverse effects of caffeine.
Green tea contains caffeine. Fluvoxamine reduces caffeine metabolism.

Likelihood Probable Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use might have additive adverse hepatotoxic effects.
Green tea extract supplements have been linked to several cases of hepatotoxicity and might have additive hepatotoxic effects with other drugs..

Likelihood Unlikely Evidence D
Imatinib (Gleevec)

Theoretically, green tea might reduce the levels and clinical effects of imatinib.
In animal research, a single dose of green tea extract reduces the area under the curve (AUC) of imatinib by up to approximately 64% and its main metabolite N-desmethyl imatinib by up to approximately 81%. This interaction has not been shown in humans. The mechanism of action is unclear but may involve multiple pathways.

Guggul extract9 drug types · 757 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, guggul might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
In vitro research and preliminary clinical studies suggest that guggul might have antiplatelet and anticoagulant effects.

Likelihood Possible Evidence B
Contraceptive Drugs

Theoretically, guggul might increase the risk of adverse effects when taken with contraceptive drugs.
In vitro research shows that guggul has estrogen-alpha receptor agonist activity.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, guggul might reduce the effects of CYP3A4 substrates.
In vitro research shows that guggul constituents known as guggulsterones can induce CYP3A4.

Likelihood Probable Evidence D
Diltiazem (Cardizem, Others)

Guggul might reduce the effects of diltiazem.
A small pharmacokinetic study shows that concomitant use of guggul with diltiazem reduces the bioavailability of diltiazem.

Likelihood Probable Evidence B
Estrogens

Theoretically, guggul might increase the risk of adverse effects when taken with estrogens.
In vitro research shows that guggul constituents known as guggulsterones have estrogen-alpha receptor agonist activity.

Likelihood Possible Evidence D
Propranolol (Inderal)

Guggul might reduce the effects of propranolol.
A small pharmacokinetic study shows that concomitant use of guggul with propranolol reduces the bioavailability of propranolol.

Likelihood Probable Evidence B
Rosuvastatin (Crestor)

Theoretically, guggul might increase the effects and adverse effects of rosuvastatin.
Animal research shows that guggul increases the bioavailability and hypolipidemic effects of rosuvastatin. The mechanism of this interaction is unclear.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, guggul might interfere with tamoxifen therapy.
In vitro research shows that guggul has estrogen-alpha receptor agonist activity.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, guggul might increase the risk for adverse effects when taken with thyroid hormone therapy.
Animal research suggests that guggul has thyroid-stimulating effects.

Cinnamon bark extract2 drug types · 442 drugs

Antidiabetes Drugs

Theoretically, cassia cinnamon may have additive effects with antidiabetes drugs.
Cassia cinnamon may lower blood glucose levels, and have additive effects in patients treated with antidiabetic agents. Dose adjustments to diabetes medications might be necessary.

Likelihood Possible Evidence B
Hepatotoxic Drugs

Theoretically, large doses of cassia cinnamon might cause additive effects when used with hepatotoxic drugs.
There is some concern that ingesting large amounts of cassia cinnamon for an extended duration might cause hepatotoxicity in some people. Cassia cinnamon contains coumarin, which can cause hepatotoxicity in animal models. In humans, very high doses of coumarin from 50-7000 mg/day can result in hepatotoxicity that resolves when coumarin use is discontinued. Lower amounts might also cause liver problems in sensitive people, such as those with liver disease or those taking potentially hepatotoxic agents.

Likelihood Possible Evidence D
Cinnamon bark extract full monograph & interactions

Fenugreek Seed Extract9 drug types · 389 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, fenugreek might have additive effects when used with anticoagulant or antiplatelet drugs.
Some of the constituents in fenugreek have antiplatelet effects in animal and in vitro research. However, common fenugreek products might not contain sufficient concentrations of these constituents for clinical effects. A clinical study in patients with coronary artery disease or diabetes shows that taking fenugreek seed powder 2.5 grams twice daily for 3 months does not affect platelet aggregation, fibrinolytic activity, or fibrinogen levels .

Likelihood Unlikely Evidence B
Antidiabetes Drugs

Theoretically, fenugreek seed might have additive hypoglycemic effects when used with antidiabetes drugs.
Clinical research shows that fenugreek seed can reduce fasting blood glucose and 2-hour postprandial glucose levels in adults with type 2 diabetes.

Likelihood Probable Evidence B
Clopidogrel (Plavix)

Theoretically, fenugreek seed might alter the clinical effects of clopidogrel by inhibiting its conversion to the active form.
Animal research shows that fenugreek seed 200 mg/kg daily for 14 days increases the maximum serum concentration of clopidogrel by 21%. It is unclear how this affects the pharmacokinetics of the active metabolite of clopidogrel; however, this study found that concomitant use of fenugreek seed and clopidogrel prolonged bleeding time by an additional 11%.

Likelihood Possible Evidence D
Metoprolol (Toprol)

Theoretically, fenugreek seed might have additive hypotensive effects when used with metoprolol.
Animal research shows that fenugreek seed 300 mg/kg daily for 2 weeks decreases systolic and diastolic blood pressure by 9% and 11%, respectively, when administered alone, and by 15% and 22%, respectively, when given with metoprolol 10 mg/kg.

Likelihood Probable Evidence B
Phenytoin (Dilantin)

Theoretically, fenugreek might decrease plasma levels of phenytoin.
Animal research shows that taking fenugreek seeds for 1 week decreases maximum concentrations and the area under the curve of a single dose of phenytoin by 44% and 72%, respectively. This seems to be related to increased clearance. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Sildenafil (Viagra)

Theoretically, concurrent use of sildenafil and fenugreek might reduce levels and therapeutic effects of sildenafil.
Animal research shows that taking fenugreek seeds for 1 week reduces maximum concentrations and the area under the curve of a single dose of sildenafil by 27% and 48%, respectively. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Theophylline

Theoretically, fenugreek may reduce the levels and clinical effects of theophylline.
Animal research shows that fenugreek 50 grams daily for 7 days reduces the maximum serum concentration (Cmax) of theophylline by 28% and the area under the plasma drug concentration-time curve (AUC) by 22%.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, fenugreek might have additive effects with warfarin and increase the international normalized ratio (INR).
Some fenugreek constituents have antiplatelet effects, although these might not be present in concentrations that are clinically significant. In one case report, a patient taking warfarin experienced an increased INR when starting to take fenugreek in combination with boldo.

Likelihood Possible Evidence D
Antihypertensive Drugs

Fenugreek may also have an additive effect on blood pressure-lowering medications. Studies on animals have shown that fenugreek seed can decrease both systolic and diastolic blood pressure by up to 22% when combined with metoprolol. Therefore, it is essential to monitor your blood pressure regularly if you are taking fenugreek and metoprolol together or any other antihypertensive drugs.

Phosphatidylserine2 drug types · 219 drugs

Anticholinergic Drugs

Theoretically, phosphatidylserine might decrease the effectiveness anticholinergic drugs.
Phosphatidylserine is thought to increase acetylcholine levels, which could theoretically interfere with the activity of anticholinergic agents.

Likelihood Possible Evidence B
Cholinergic Drugs

Theoretically, phosphatidylserine might have additive effects with cholinergic drugs.
Phosphatidylserine is thought to increase acetylcholine levels, which could theoretically lead to additive cholinergic effects when used with cholinergic drugs.

B. subtilis DE1111 drug type · 182 drugs

Antibiotic Drugs

Theoretically, taking Bacillus subtilis with antibiotic drugs might decrease the effectiveness of B. subtilis.
Since B. subtilis preparations usually contain live and active organisms, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and B. subtilis preparations by at least 2 hours.

Likelihood Probable Evidence D
B. subtilis DE111 full monograph & interactions

Chromium5 drug types · 178 drugs

Antidiabetes Drugs

Theoretically, chromium may have additive effects with antidiabetic agents and increase the risk of hypoglycemia.
Some research shows that taking chromium might lower blood glucose levels, especially in patients with poorly controlled type 2 diabetes.

Likelihood Possible Evidence A
Insulin

Theoretically, concomitant use of chromium and insulin might increase the risk of hypoglycemia.
In clinical research, chromium has been shown to increase insulin sensitivity,

Likelihood Possible Evidence B
Levothyroxine (Synthroid, Others)

Chromium might bind levothyroxine in the intestinal tract and decrease levothyroxine absorption.
Clinical research in healthy volunteers shows that taking chromium picolinate 1000 mcg with levothyroxine 1 mg decreases serum levels of levothyroxine by 17% when compared to taking levothyroxine alone. Advise patients to take levothyroxine at least 30 minutes before or 3-4 hours after taking chromium.

Likelihood Probable Evidence B
Aspirin

Theoretically, aspirin might increase chromium absorption.
Animal research suggests that aspirin may increase chromium absorption and chromium levels in the blood.

Likelihood Possible Evidence D
Nonsteroidal Anti-Inflammatory Drugs (Nsaids)

NSAIDs might increase chromium levels in the body.
Drugs that are prostaglandin inhibitors, such as NSAIDs, seem to increase chromium absorption and retention.

Veda Lean by Prajna Ayurveda: Common Questions

Does Veda Lean by Prajna Ayurveda interact with any medications?
Yes. Based on its ingredients, Veda Lean has a known interaction with 1,635 medications, including 13 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Veda Lean contains 9 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will Veda Lean help me lose weight?
The product contains ingredients like green tea and guggul that are used in traditional weight-management formulas, but the evidence we hold shows guggul is rated possibly ineffective for obesity. Green tea is rated for other uses (HPV, ovarian cancer, cholesterol) rather than weight loss specifically. Effectiveness for weight loss isn't established in our data, so talk with your doctor about realistic expectations.
Can I take Veda Lean if I'm pregnant?
Several ingredients in this product should be avoided or limited during pregnancy—amla, cinnamon, fenugreek, and guggul all have safety concerns or insufficient data for pregnancy. Green tea at food amounts is likely acceptable, but high-dose extracts should be limited. Chromium from a balanced diet or prenatal vitamin is generally okay, but extra supplement doses should be avoided. Talk with your doctor before taking this product while pregnant.
What are the most common side effects?
The most frequent side effects come from green tea and guggul and are generally mild: bloating, constipation, diarrhea, nausea, and gastrointestinal upset. Guggul and cinnamon may also cause skin reactions like rash or itching in some people. If you experience digestive upset, try taking it with food or reducing the dose.
Is this safe to take with antibiotics?
The product contains Bacillus subtilis, a probiotic, which may be killed by antibiotics if taken at the same time. Separate your antibiotic dose from this supplement by at least 2–3 hours, and talk to your pharmacist about the best timing for your specific antibiotic.
Can I take Veda Lean while breastfeeding?
Green tea contains caffeine, which passes into breast milk and can affect your baby at high doses; keep intake moderate and avoid concentrated supplements. Amla, guggul, phosphatidylserine, and Bacillus subtilis all have limited or insufficient safety data during breastfeeding, so it's best to avoid this product or discuss it with your doctor or lactation specialist first.
What's in the 'Traditional Ayurvedic Blend' listed on the label?
The product notes that as a blend container, so its specific active components are listed separately—they include chebulic myrobalan, belleric myrobalan, and other ingredients already covered in this product. The label should show the blend's total amount; if you need the breakdown of each ingredient within it, contact the manufacturer directly.
