HelloPharmacist Scorecard of Core by TLS Weight Loss Solution
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Low disclosure
Core contains 11 active ingredients: vitamin A, beta-carotene, calcium, chromium, blue-green algae, guar gum, bitter melon fruit extract, pomegranate extract, locust bean gum, white kidney bean extract, and a proprietary blend called LeptiCore. Vitamin A and beta-carotene are both forms of vitamin A, which your body uses for vision and immune function.
Calcium supports bone and tooth strength. Chromium plays a role in blood sugar regulation.
Blue-green algae and bitter melon are traditional plant extracts; pomegranate and locust bean gum provide plant compounds and fiber. Guar gum and locust bean gum are both fiber sources that thicken the formula.
The product also contains several inactive ingredients—microcrystalline cellulose, croscarmellose sodium, stearic acid, hypromellose, polyethylene glycol, hydroxypropyl cellulose, magnesium stearate, and silica—which serve as fillers, binders, and capsule material.
Does it work?
Moderate evidence
Vitamin A is effective for treating vitamin A deficiency and possibly effective for oral leukoplakia, aging skin, measles, ulcerative colitis, and bronchopulmonary dysplasia. Calcium is effective for kidney failure and dyspepsia, and likely effective for osteoporosis.
Chromium is likely effective for chromium deficiency and possibly effective for diabetes. For other claims in this product—such as blue-green algae for hypertension, guar gum for cholesterol and IBS, bitter melon for blood sugar control, pomegranate for blood pressure, and locust bean gum for diarrhea—the evidence we hold ranges from possibly effective to insufficient to rate.
White Kidney Bean Extract and Indian Gum Arabic have no effectiveness data on file.
How safe is it?
Well-documented data
Vitamin A is generally well tolerated at recommended doses, but high doses (especially as retinol) can be toxic because it builds up in the body and may cause birth defects—avoid high-dose supplements in pregnancy unless your doctor directs it. Calcium is generally safe at recommended amounts and is considered likely safe in pregnancy and breastfeeding when you stay within recommended intake.
Chromium is usually well tolerated at typical supplement doses; small amounts from food or a prenatal vitamin are acceptable in pregnancy, but extra supplements should be avoided unless advised by your doctor. Blue-green algae quality varies and contamination risk is a concern, so the data advise against it.
Guar gum is generally well tolerated but must be taken with plenty of water to avoid choking or blockage. Bitter melon is traditionally avoided in pregnancy because seeds and high doses may cause harmful effects, and there isn't enough safety information for breastfeeding—talk with your doctor.
Pomegranate fruit and juice are generally safe as food; the concentrated extract's safety during pregnancy and breastfeeding is possibly safe but limited. Locust bean gum (carob) is generally recognized as safe in normal food amounts.
Meds to double-check
Major interaction found
Before you take Core, double-check with your own doctor or pharmacist if you take retinoid medications (Major interaction with vitamin A and beta-carotene), HIV integrase inhibitors or ceftriaxone (Major with calcium), or any blood thinners, diabetes or insulin medications, blood pressure drugs, thyroid medication (levothyroxine), tetracycline antibiotics, heart rhythm drugs, cholesterol medications, cancer drugs like pazopanib, or oral medications in general. Guar gum can reduce absorption of many oral drugs—separate your doses by 30–60 minutes.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Core is a multingredient weight-loss formula with some established uses (vitamin A for deficiency, calcium for bone health) and others with limited or unclear evidence. If you take any medications—especially blood thinners, diabetes drugs, blood pressure medications, thyroid medication, HIV medications, or tetracycline antibiotics—you need to check this product against your exact prescriptions before starting, because the interactions are numerous and some are serious.
Talk with your own doctor or pharmacist to confirm it's safe for your situation.

Core by TLS Weight Loss Solution Drug Interactions
HelloPharmacist Interaction Report
Core by TLS Weight Loss Solution interacts with medications through its vitamin A, beta-carotene, calcium, chromium, blue-green algae, guar gum, bitter melon fruit extract, and pomegranate extract content.
The most serious concern is a Major interaction: vitamin A and beta-carotene can combine with retinoid medications (like tretinoin and isotretinoin) to cause dangerously high vitamin A levels and additive toxicity.
Read the full breakdown — every affected drug type, severity by severity
Vitamin A and beta-carotene also carry Moderate interactions with blood thinners like warfarin (increased bleeding risk), tetracycline antibiotics (increased risk of benign intracranial hypertension), and drugs that stress the liver. Calcium has Major interactions with HIV integrase inhibitors (dolutegravir, elvitegravir) and the antibiotic ceftriaxone, and Moderate interactions with thyroid medication (levothyroxine), heart drugs (diltiazem, sotalol), and a topical psoriasis treatment.
Chromium may lower blood sugar additively with diabetes medications and insulin, and may reduce thyroid medication absorption. Blue-green algae, guar gum, bitter melon, and pomegranate each carry Moderate interactions with blood sugar and blood pressure medications, plus other drug classes.
Guar gum can reduce absorption of many oral medications if taken at the same time; separate doses by 30–60 minutes. Bitter melon may increase levels of pazopanib (a cancer drug).
Pomegranate may increase bleeding risk with warfarin, raise levels of drugs broken down by the liver enzyme CYP2D6, and theoretically increase effects of blood pressure and cholesterol medications.
Altogether, these interactions span 2,257 individual medications. We could not check White Kidney Bean Extract or Indian Gum Arabic — no interaction data is on file for them.

Guar Gum
Ethinyl Estradiol
Theoretically, guar gum might reduce the absorption of ethinyl estradiol, potentially decreasing its effectiveness.
Animal research shows that taking guar gum with ethinyl estradiol decreases ethinyl estradiol absorption. However, this effect has not been reported in humans.
Metformin (Glucophage)
Guar gum might reduce the absorption of metformin, potentially decreasing its effectiveness.
A small study in healthy volunteers shows that guar gum reduces the absorption rate of metformin.
Oral Drugs
Guar gum might reduce the absorption of some oral drugs, potentially decreasing their effectiveness.
Clinical research shows that guar gum reduces or slows absorption of medications such as penicillin and metformin. To avoid changes in absorption, take guar gum 30-60 minutes after oral medications.
Penicillin
Guar gum might reduce the absorption of penicillin, potentially decreasing its effectiveness.
A small clinical study in healthy volunteers shows that taking guar gum with penicillin results in decreased penicillin absorption and reduced penicillin levels.
Digoxin (Lanoxin)
Guar gum might slow digoxin absorption, but it does not seem to impact how much digoxin is absorbed overall.
Two small studies in healthy volunteers show no change in the overall extent of digoxin absorption, although early absorption was slowed, when taken with guar gum.
Locust Bean Gum
Oral Drugs
Theoretically, carob might also impair the absorption of oral drugs.
Laboratory research shows that carob, when consumed as part of the diet or used as a thickening agent in infant formula, reduces the absorption of certain minerals. Take carob 30-60 minutes after oral medications.
Pomegranate extract
Ace Inhibitors (Aceis)
Theoretically, taking pomegranate with ACEIs might increase the risk of adverse effects.
Pomegranate juice is thought to have ACE inhibitor-like effects.
Antihypertensive Drugs
Theoretically, taking pomegranate with antihypertensive drugs might increase the risk of hypotension.
Consuming pomegranate juice can modestly lower blood pressure.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, pomegranate might increase levels of drugs metabolized by CYP2D6.
In vitro, pomegranate juice inhibits CYP2D6. However, the clinical significance of this potential interaction in humans is not known.
Rosuvastatin (Crestor)
Theoretically, taking pomegranate with rosuvastatin might increase the risk of adverse effects.
In one case, a patient taking rosuvastatin 5 mg every other day in combination with ezetimibe 10 mg daily developed rhabdomyolysis after drinking pomegranate juice 200 mL twice weekly for 3 weeks. This patient had a history of elevated creatine kinase levels while not receiving any statin treatment. This suggests a possible underlying myopathy and predisposition to rhabdomyolysis.
Warfarin (Coumadin)
Theoretically, pomegranate might increase warfarin levels and increase the risk of bleeding. Also, discontinuing regular consumption of pomegranate juice might decrease warfarin levels.
In one case report, a patient had a stable, therapeutic bleeding time, as measured by international normalized ratio (INR), while taking warfarin in combination with pomegranate juice 2-3 times per week. The patient became subtherapeutic within about 10 days after discontinuing pomegranate juice, which required a warfarin dose increase. In another case report, a patient with a stable INR for over one year presented with an INR of 14. The patient noted no changes to medications or diet but did report consuming around 3 liters of pomegranate juice over the previous week. The patient's INR stabilized upon moderation of pomegranate juice consumption. The mechanism of this potential interaction is unclear.
Carbamazepine (Tegretol)
Theoretically, taking pomegranate with carbamazepine might increase the risk of adverse effects, although research suggests this interaction is unlikely to be clinically significant.
Animal research shows that pomegranate juice may inhibit cytochrome P450 3A4 (CYP3A4) metabolism of carbamazepine and increase levels of carbamazepine by 1.5 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP3A4, but might not inhibit hepatic CYP3A4. However, some human research suggests that pomegranate does not significantly inhibit CYP3A4 drug metabolism in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, pomegranate might increase levels of drugs metabolized by CYP2C9.
Some animal and in vitro research shows that pomegranate juice inhibits intestinal, but not hepatic, CYP2C9 isoenzyme activity. However, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, pomegranate might increase levels of drugs metabolized by CYP3A4, but most research suggests this interaction is unlikely to be clinically significant.
Pomegranate contains several polyphenols that have individually been shown to inhibit CYP3A4. However, there is contradictory evidence about the effect of whole pomegranate juice on CYP3A4 activity. In vitro, pomegranate juice significantly inhibits the CYP3A4 enzyme, with comparable inhibition to grapefruit juice. In an animal model, pomegranate juice inhibits CYP3A4 metabolism of carbamazepine and increases levels of carbamazepine by 1.5 times; however, in human volunteers, drinking a single glass of pomegranate juice 240 mL or taking 200 mL daily for 2 weeks does not significantly affect levels of the CYP3A4 substrate midazolam after oral or intravenous administration. Another study in healthy volunteers shows that consuming pomegranate juice 300 mL three times daily for three days also does not significantly affect levels of simvastatin, a CYP3A4 substrate This suggests that pomegranate is unlikely to significantly affect levels of CYP3A4 substrates in humans.
Tolbutamide (Orinase)
Theoretically, pomegranate might increase levels of tolbutamide, although research suggests this interaction is unlikely to be clinically significant.
Animal research shows that pomegranate juice inhibits the cytochrome P450 2C9 (CYP2C9) metabolism of tolbutamide. Pomegranate juice increased tolbutamide levels by 1.2 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP2C9, but might not inhibit hepatic CYP2C9. Despite this evidence, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans. This interaction does not appear to be clinically significant in humans.
Vitamin A
Retinoids
Concomitant use of retinoids with vitamin A supplements might produce supratherapeutic vitamin A levels.
Retinoids, which are vitamin A derivatives, could have additive toxic effects when taken with vitamin A supplements.
Hepatotoxic Drugs
Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure.
Tetracycline Antibiotics
Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.
Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition. Avoid high doses of vitamin A in people taking tetracyclines chronically.
Warfarin (Coumadin)
Theoretically, high doses of vitamin A could increase the risk of bleeding with warfarin.
Vitamin A toxicity is associated with hemorrhage and hypoprothrombinemia, possibly due to vitamin K antagonism. Advise patients taking warfarin to avoid doses of vitamin A above the tolerable upper intake level of 10,000 IU/day for adults.
Blue-Green Algae
Anticoagulant/Antiplatelet Drugs
Theoretically, spirulina blue-green algae might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs. However, this is unlikely.
Spirulina blue-green algae have shown antiplatelet and anticoagulant effects in vitro. However, one preliminary study in 24 patients receiving spirulina blue-green algae 2.3 grams daily for 2 weeks showed no effect on platelet activation or measures of clotting time.
Antidiabetes Drugs
Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.
Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs. However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes. A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects.
Immunosuppressants
Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Blue-green algae have been shown to stimulate the immune system.
Bitter Melon fruit extract
Antidiabetes Drugs
Taking bitter melon with antidiabetes drugs might increase the risk of hypoglycemia.
Bitter melon can lower blood glucose levels and might have additive effects when used with antidiabetes drugs. This might increase the risk of hypoglycemia in some patients. Monitor blood glucose levels closely.
P-Glycoprotein Substrates
Theoretically, bitter melon might increase levels of P-glycoprotein substrates.
Bitter melon might inhibit the p-glycoprotein (P-gp) intestinal pump and increase intracellular levels of P-gp substrates. In vitro research in intestinal cells shows that 1-monopalmitin, a constituent of bitter melon, increases levels of daunomycin, a P-gp substrate. Additionally, drinking bitter melon juice has been associated with a case of acute pancreatitis in a patient who had been taking pazopanib, a P-gp substrate, for 8 years. Researchers theorize that inhibition of P-gp led to increased levels of pazopanib, resulting in pazopanib-induced pancreatitis.
Pazopanib (Votrient)
Theoretically, bitter melon might increase levels of pazopanib, potentially increasing the risk of adverse effects.
In one case, a 65-year-old patient taking pazopanib for 8 years for renal cell carcinoma experienced signs and symptoms consistent with acute pancreatitis 4 days after drinking bitter melon juice at a dose of 100-150 mL daily. The patient's symptoms, amylase levels, and lipase levels improved upon discontinuation of bitter melon and pazopanib. Pazopanib treatment was re-initiated with no further evidence of pancreatitis. Researchers theorize that inhibition of P-glycoprotein by bitter melon led to increased levels of pazopanib, a P-glycoprotein substrate, resulting in pazopanib-induced pancreatitis.
Chromium
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.
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,
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.
Aspirin
Theoretically, aspirin might increase chromium absorption.
Animal research suggests that aspirin may increase chromium absorption and chromium levels in the blood.
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.
Calcium
Ceftriaxone (Rocephin)
Co-administration of intravenous calcium and ceftriaxone can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys.
Avoid administering intravenous calcium in any form, such as parenteral nutrition or Lactated Ringers, within 48 hours of intravenous ceftriaxone. Case reports in neonates show that administering intravenous ceftriaxone and calcium can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys. In several cases, neonates have died as a result of this interaction. So far there are no reports in adults; however, there is still concern that this interaction might occur in adults.
Dolutegravir (Tivicay)
Calcium seems to reduce levels of dolutegravir.
Advise patients to take dolutegravir either 2 hours before or 6 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium carbonate 1200 mg concomitantly with dolutegravir 50 mg reduces plasma levels of dolutegravir by almost 40%. Calcium appears to decrease levels of dolutegravir through chelation.
Elvitegravir (Vitekta)
Calcium seems to reduce levels of elvitegravir.
Advise patients to take elvitegravir either 2 hours before or 2 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium along with elvitegravir can reduce blood levels of elvitegravir through chelation.
Aluminum
Calcium citrate might increase aluminum absorption and toxicity. Other types of calcium do not increase aluminum absorption.
Calcium citrate can increase the absorption of aluminum when taken with aluminum hydroxide. The increase in aluminum levels may become toxic, particularly in individuals with kidney disease. However, the effect of calcium citrate on aluminum absorption is due to the citrate anion rather than calcium cation. Calcium acetate does not appear to increase aluminum absorption.
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)
Calcium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption when taken in a fasting state.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide and calcium can be taken together if taken with food. However, if taken on an empty stomach, bictegravir/emtricitabine/tenofovir alafenamide should not be taken with, or 2 hours after, calcium containing products.
Bisphosphonates
Calcium reduces the absorption of bisphosphonates.
Advise patients to take bisphosphonates at least 30 minutes before calcium, but preferably at a different time of day. Calcium supplements decrease absorption of bisphosphonates.
Calcipotriene (Dovonex)
Taking calcipotriene with calcium might increase the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with calcium supplements might increase the risk of hypercalcemia.
Digoxin (Lanoxin)
Using intravenous calcium with digoxin might increase the risk of fatal cardiac arrhythmias.
Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. However, one retrospective analysis of clinical data suggests that intravenous calcium does not increase the risk of dysrhythmias or mortality in patients receiving digoxin.
Diltiazem (Cardizem, Others)
Theoretically, calcium may reduce the therapeutic effects of diltiazem.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, calcium might increase this risk of hypercalcemia and reduce the effectiveness of diltiazem.
Levothyroxine (Synthroid, Others)
Calcium seems to reduce the absorption and effectiveness of levothyroxine.
Advise patients to take levothyroxine and calcium supplements at least 4 hours apart. Calcium reduces levothyroxine absorption, probably by forming insoluble complexes. Calcium carbonate supplements reduce effectiveness of levothyroxine in patients with hypothyroidism.
Lithium
Theoretically, concomitant use of calcium and lithium may increase this risk of hypercalcemia.
Clinical research suggests that long-term use of lithium may cause hypercalcemia in 10% to 60% of patients. Theoretically, concomitant use of lithium and calcium supplements may further increase this risk.
Quinolone Antibiotics
Calcium seems to reduce the absorption of quinolone antibiotics.
Advise patients to take oral quinolones at least 2 hours before or 4-6 hours after calcium supplements or calcium-fortified foods. Taking calcium at the same time as oral quinolones can reduce quinolone absorption. Calcium binds to quinolones in the gut.
Raltegravir (Isentress)
Calcium may reduce levels of raltegravir.
Pharmacokinetic research shows that taking a single dose of calcium carbonate 3000 mg along with raltegravir 400 mg twice daily modestly decreases the mean area under the curve of raltegravir, but the decrease does not necessitate a dose adjustment of raltegravir. However, a case of elevated HIV-1 RNA levels and documented resistance to raltegravir has been reported for a patient taking calcium carbonate 1 gram three times daily plus vitamin D3 (cholecalciferol) 400 IU three times daily in combination with raltegravir 400 mg twice daily for 11 months. It is thought that calcium reduced raltegravir levels by chelation, leading to treatment failure.
Sotalol (Betapace)
Calcium seems to reduce the absorption of sotalol.
Advise patients to separate doses by at least 2 hours before or 4-6 hours after calcium. Calcium appears to reduce the absorption of sotalol, probably by forming insoluble complexes.
Tetracycline Antibiotics
Calcium seems to reduce the absorption of tetracycline antibiotics.
Advise patients to take oral tetracyclines at least 2 hours before, or 4-6 hours after calcium supplements. Taking calcium at the same time as oral tetracyclines can reduce tetracycline absorption. Calcium binds to tetracyclines in the gut.
Thiazide Diuretics
Taking calcium along with thiazides might increase the risk of hypercalcemia and renal failure.
Thiazides reduce calcium excretion by the kidneys. Using thiazides along with moderately large amounts of calcium carbonate increases the risk of milk-alkali syndrome (hypercalcemia, metabolic alkalosis, renal failure). Patients may need to have their serum calcium levels and/or parathyroid function monitored regularly.
Verapamil (Calan, Others)
Theoretically, calcium may reduce the therapeutic effects of verapamil.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, use of calcium supplements may increase this risk of hypercalcemia and reduce the effectiveness of verapamil.
Calcium Channel Blockers
Intravenous calcium may decrease the effects of calcium channel blockers; oral calcium is unlikely to have this effect.
Intravenous calcium is used to decrease the effects of calcium channel blockers in the management of overdose. Intravenous calcium gluconate has been used before intravenous verapamil (Isoptin) to prevent or reduce the hypotensive effects without affecting the antiarrhythmic effects. But there is no evidence that dietary or supplemental calcium when taken orally interacts with calcium channel blockers.
