What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 5 of its 5 active ingredients.
  • “Bioperine Nature's Thermonutrient” is listed as a grouped ingredient — the label gives one combined amount (1 mg) without saying how much of each component you get.
  • “AKBA 90” is listed as a grouped ingredient — the label gives one combined amount (60 mg) without saying how much of each component you get.

AKBA Plus contains 5 active ingredients. Fenugreek powder is the one we have interaction and safety data for; it's traditionally used for sexual function, menstrual discomfort, and blood sugar support.

The other four — piperine, 3-O-acetyl-11-keto beta boswellic acid, AKBA 90, boswellin PS, and the Bioperine thermonutrient blend — are included for their roles in the formula, though we don't hold detailed monographs on all of them. The capsule also contains inactive ingredients (inulin, cellulose, and stearate) that serve as fillers and binders.

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: Joint pain and inflammatory support.
  • We looked for evidence on: Joint pain, Rheumatoid arthritis (RA), Pain (chronic), Myalgia, Osteoarthritis, Joint inflammation — and 1 related terms.
  • The strongest evidence on file: Boswellia Serrata is rated "Possibly Effective" for Osteoarthritis (Natural Medicines).
  • Also on file: Boswellia Serrata is rated "Insufficient Reliable Evidence To Rate" for Rheumatoid arthritis (RA).
  • Also on file: Fenugreek is rated "Insufficient Reliable Evidence To Rate" for Myalgia, Joint pain.

Fenugreek in this product is rated possibly effective for sexual dysfunction, sexual arousal, dysmenorrhea (menstrual cramps), and type 2 diabetes based on the evidence we hold. That means some clinical research supports these uses, but the data isn't yet conclusive.

We don't have effectiveness ratings on file for the other ingredients in AKBA Plus.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Fenugreek is generally well tolerated when eaten as food, but supplement doses may cause side effects. The most common ones from clinical use are abdominal pain, bloating, diarrhea, heartburn, gas, low blood sugar (hypoglycemia), and nausea.

Rare but serious allergic reactions — including severe swelling (angioedema), airway constriction (bronchospasm), and anaphylaxis — have been reported. Avoid medicinal use of fenugreek during pregnancy, as supplement amounts may affect the uterus.

If you're breastfeeding and considering fenugreek to boost milk supply, discuss it with your provider first — it's often used for this, but the evidence is limited and we need more data. One odd side effect: fenugreek can cause an unusual body odor in newborns and children, which some parents have mistaken for maple syrup urine disease (a serious genetic condition), though it does not cause lasting harm.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Boswellia Serrata, Fenugreek, Black Pepper.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,253 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking AKBA Plus, double-check if you're on blood thinners (warfarin, clopidogrel) or antiplatelet drugs — fenugreek may increase bleeding risk. Also verify diabetes medications, blood pressure drugs (especially beta blockers like metoprolol), theophylline for breathing, phenytoin for seizures, or sildenafil for sexual function.

Fenugreek may reduce how well some of these work or add to their effects. Run your medication list through the checker on this page.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

AKBA Plus is aimed at people looking to support sexual function, menstrual health, or blood sugar — fenugreek shows promise for these. But if you take blood thinners, diabetes drugs, blood pressure medication, or certain other prescriptions, you'll want to check with us or your pharmacist first.

Even if you're generally healthy, side effects like gas and digestive upset are common, and allergic reactions, though rare, can be serious.

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

Theoretically, black pepper might increase levels of drugs metabolized by CYP3A4.
In vitro research and pharmacokinetic simulation data suggest that piperine, a constituent of black pepper, as well as the pepper fruit seem to inhibit CYP3A4. This has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, black pepper might increase blood levels of lithium due to its diuretic effects. The dose of lithium might need to be reduced.
Black pepper is thought to have diuretic properties.

Likelihood Probable Evidence D
Nevirapine (Viramune)

Black pepper might increase blood levels of nevirapine.
Clinical research shows that piperine, a constituent of black pepper, increases the plasma concentration of nevirapine. However, no adverse effects were observed in this study.

Likelihood Probable Evidence D
P-Glycoprotein Substrates

Animal research shows that piperine, a constituent of black pepper, increases pentobarbital-induced sleeping time.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Black pepper might increase blood levels of phenytoin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption, slow elimination, and increase levels of phenytoin. Taking a single dose of black pepper 1 gram along with phenytoin seems to double the serum concentration of phenytoin. Consuming a soup with black pepper providing piperine 44 mg/200 mL of soup along with phenytoin also seems to increase phenytoin levels when compared with consuming the same soup without black pepper.

Likelihood Possible Evidence B
Propranolol (Inderal)

Black pepper might increase blood levels of propranolol.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of propranolol.

Likelihood Possible Evidence B
Rifampin (Rifadin)

Likelihood Possible Evidence B
Theophylline

Black pepper might increase blood levels of theophylline.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of theophylline.

Likelihood Possible Evidence D
Amoxicillin (Amoxil, Trimox)

Theoretically, black pepper might increase the effects and side effects of amoxicillin.
Animal research shows that taking piperine, a constituent of black pepper, with amoxicillin increases plasma levels of amoxicillin. This has not been reported in humans.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, black pepper might increase blood levels of carbamazepine, potentially increasing the effects and side effects of carbamazepine.
One clinical study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that taking a single 20 mg dose of purified piperine, a constituent of black pepper, increases carbamazepine levels. Piperine may increase carbamazepine absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or inhibiting cytochrome P450 3A4 (CYP3A4) in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects. In vitro research also shows that piperine can increase carbamazepine levels by 11% in a time-dependent manner.

Likelihood Possible Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, black pepper might decrease levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that black pepper induces CYP1A2. This has not been reported in humans.

Likelihood Possible Evidence D

Boswellin PS6 drug types · 952 drugs

Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, Boswellia serrata might increase the levels of CYP1A2 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP1A2 enzymes.

Theoretically, Boswellia serrata might increase the levels of CYP2D6 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP2D6 enzymes.

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

Theoretically, Boswellia serrata might increase or decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP3A4 enzymes. Other in vitro research shows that Boswellia serrata extract inhibits CYP3A4 enzymes at most concentrations, although it may modestly induce enzyme activity at low concentrations.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, Boswellia serrata might alter the effects of immunosuppressive drugs.
Some in vitro research suggests that Boswellia serrata extracts might inhibit mediators of autoimmune disorders such as leukotrienes and reduce production of antibodies and cell-mediated immunity. However, other in vitro research suggests that, when coupled with calcium ions, boswellic acids containing the keto group have immunostimulant properties within specific cell signaling pathways.

Likelihood Possible Evidence D

Fenugreek, Powder9 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.

AKBA Plus by True Botanica: Common Questions

Does AKBA Plus by True Botanica interact with any medications?
Yes. Based on its ingredients, AKBA Plus has a known interaction with 1,252 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
AKBA Plus contains 5 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.
Can I take AKBA Plus if I'm pregnant?
No. Medicinal doses of fenugreek (the active ingredient we have data on) are not advised during pregnancy because supplement amounts may affect the uterus. Talk with your doctor or midwife before using it.
Does AKBA Plus work for erectile dysfunction?
Fenugreek is rated possibly effective for sexual dysfunction and sexual arousal based on clinical research we hold — meaning some studies support it, but the evidence isn't conclusive yet. Results vary person to person.
What are the most common side effects?
Fenugreek commonly causes abdominal pain, bloating, diarrhea, heartburn, gas, and nausea. Most people tolerate it, but digestive upset is the main complaint. Rare serious allergic reactions have been reported.
Can fenugreek lower my blood sugar?
Yes. Fenugreek can reduce fasting blood glucose and may lower blood sugar further when you're also taking diabetes medication — that's why it's a Moderate-severity interaction. If you have diabetes, check with your pharmacist before starting.
Does AKBA Plus have any fillers?
Yes, it contains inactive ingredients — inulin, cellulose, and stearate — that serve as fillers and binders to form the capsule and help it dissolve properly.
Can I use AKBA Plus while breastfeeding to boost milk supply?
Fenugreek is often used for this, but the evidence is limited and we don't have enough data to say it's safe or effective for that purpose. Talk with your doctor, midwife, or lactation consultant before trying it.
