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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Fermented Maca contains three active ingredients: organic maca, organic schisandra, and organic cardamom. The product also includes several inactive ingredients—organic brown rice, maltodextrin, organic gum acacia, a proprietary ferment media blend, silicon dioxide, lac resin, and carnauba wax—which serve as fillers, binders, and processing aids.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: adaptogenic vitality and energy support.
  • We looked for evidence on: Fatigue, Stress, Menopausal symptoms, Sexual desire, Age-related testosterone deficiency, stamina — and 2 related terms.
  • The closest evidence on file: Schisandra is rated "Insufficient Reliable Evidence To Rate" for Menopausal symptoms (Natural Medicines).
  • Also on file: Schisandra is rated "Insufficient Reliable Evidence To Rate" for Stress.
  • Also on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Fatigue, Sexual desire, Age-related testosterone deficiency.

The evidence for these ingredients is not yet established in the data we hold. Maca has been studied for amenorrhea, anemia, sexual dysfunction, athletic performance, and osteoporosis, but the evidence is insufficient to rate it for any of these uses.

Schisandra has been studied for asthma, athletic performance, cough, diabetes, diarrhea, and hepatitis, but again, evidence is insufficient to rate it. Cardamom has been evaluated for nonalcoholic fatty liver disease, respiratory infections, diabetes, indigestion, epilepsy, and high cholesterol, but the evidence is likewise insufficient.

If you're considering this product for a specific health goal, talk with your doctor or pharmacist about whether the evidence supports its use.

The evidence, ingredient by ingredient Maca Schisandra Cardamom

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.

Maca is generally well tolerated as a food, but long-term safety data in supplement amounts are limited. Raw, uncooked maca may cause stomach pain.

Schisandra is generally well tolerated short term in healthy adults, though high-quality safety data are limited. Common side effects include decreased appetite, heartburn, stomach upset, and urticaria (hives).

Cardamom in food amounts is generally well tolerated; one trial participant experienced mild skin inflammation, and a case report describes hand dermatitis in someone frequently exposed to cardamom dust. Concentrated cardamom supplements or essential oils should be avoided without medical advice.

Meds to double-check

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?
  • 1 of the 3 matched ingredients can interact with medications — Schisandra.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs.
  • For scale: 804 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 this product, check with your doctor or pharmacist if you take tacrolimus (an immunosuppressant), warfarin (a blood thinner), midazolam or other sedatives, antifungal drugs like voriconazole, or any medication metabolized by your liver's CYP3A4, CYP2C19, or CYP2C9 enzymes. Schisandra can raise levels of some of these drugs or lower the effectiveness of others.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product is not recommended during pregnancy or breastfeeding—maca lacks sufficient safety data in pregnancy, schisandra is possibly unsafe in pregnancy and lacks breastfeeding data, and while cardamom is likely safe while breastfeeding, maca and schisandra are not. If you take tacrolimus, a blood thinner, certain cancer or antifungal drugs, midazolam, or other medications metabolized by your liver, check with your doctor or pharmacist before starting this product—the schisandra content has documented interactions with these drug types.

organic Schisandra12 drug types · 803 drugs

Cyclophosphamide

Theoretically, schisandra might increase the levels and clinical effects of cyclophosphamide.
In vitro research shows that schisandra increases the concentration of cyclophosphamide, likely through inhibition of cytochrome P450 3A4. After multiple doses of the schisandra constituents schisandrin A and schisantherin A, the maximum concentration of cyclophosphamide was increased by 7% and 75%, respectively, while the overall exposure to cyclophosphamide was increased by 29% and 301%, respectively.

Likelihood Probable Evidence D
Cyclosporine (Neoral, Sandimmune)

Schisandra can increase the levels and clinical effects of cyclosporine.
A small observational study in children with aplastic anemia found that taking schisandra with cyclosporine increased cyclosporine trough levels by 93% without increasing the risk of adverse events. However, the dose of cyclosporine was reduced in 9% of children to maintain appropriate cyclosporine blood concentrations.

Likelihood Probable Evidence B
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, schisandra might increase the levels and clinical effects of CYP2C19 substrates.
In vitro research shows that schisandra inhibits CYP2C19, and animal research shows that schisandra increases the concentration of voriconazole, a CYP2C19 substrate. Theoretically, schisandra may also inhibit the metabolism of other CYP2C19 substrates. This effect has not been reported in humans.

Likelihood Probable Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, schisandra might decrease the levels and clinical effects of CYP2C9 substrates.
In vitro and animal research suggests that schisandra induces CYP2C9 enzymes. This effect has not been reported in humans.

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

Schisandra can increase the levels and clinical effects of drugs metabolized by CYP3A4.
Most clinical and laboratory research shows that schisandra, administered either as a single dose or up to twice daily for 14 days, inhibits CYP3A4 and increases the concentration of CYP3A4 substrates such as cyclophosphamide, midazolam, tacrolimus, and talinolol. Although one in vitro and animal study shows that schisandra may induce CYP3A4 metabolism, this effect appears to be overpowered by schisandra's CYP3A4 inhibitory activity and has not been reported in humans.

Likelihood Probable Evidence D
Midazolam (Versed)

Schisandra can increase the levels and clinical effects of midazolam.
A small pharmacokinetic study in healthy adults shows that taking schisandra extract (Hezheng Pharmaceutical Co.) containing deoxyschizandrin 33.75 mg twice daily for 8 days and a single dose of midazolam 15 mg on day 8 increases the overall exposure to midazolam by about 119%, increases the peak plasma level of midazolam by 86%, and decreases midazolam clearance by about 52%. This effect has been attributed to inhibition of CYP3A4 by schisandra.

Likelihood Probable Evidence B
P-Glycoprotein Substrates

Schisandra might increase the levels and clinical effects of P-glycoprotein substrates.
In vitro research shows that schisandra extracts and constituents such as schisandrin B inhibit P-glycoprotein mediated efflux in intestinal cells and in P-glycoprotein over-expressing cell lines. Additionally, a small clinical study shows that schisandra increases the peak concentration and overall exposure to talinolol, a P-glycoprotein probe substrate. Theoretically, schisandra might inhibit the efflux of other P-glycoprotein substrates.

Likelihood Possible Evidence D
Sirolimus (Rapamune)

Schisandra can increase the levels and clinical effects of sirolimus.
A small pharmacokinetic study in healthy volunteers shows that taking 3 capsules of schisandra (Hezheng Pharmaceutical Company) containing a total of 33.75 mg deoxyschizandrin twice daily for 13 days and then taking a single dose of sirolimus 2 mg increases the overall exposure and peak level of sirolimus by two-fold. This effect is thought to be due to inhibition of cytochrome P450 3A4 by schisandra, as well as possible inhibition of the P-glycoprotein drug transporter.

Likelihood Probable Evidence B
Tacrolimus (Prograf)

Schisandra can increase the levels and clinical effects of tacrolimus.
Clinical research in healthy children and adults, transplant patients, and patients with nephrotic syndrome and various rheumatic immunologic disorders shows that taking schisandra with tacrolimus increases tacrolimus peak levels by 183% to 268%, prolongs or delays time to peak tacrolimus concentrations, increases overall exposure to tacrolimus by 126% to 343%, and decreases tacrolimus clearance by 19% to 73%. This effect is thought to be due to inhibition of P-glycoprotein drug transporter and CYP3A4 and CYP3A5 by schisandra. Some clinical and observational studies suggest that schisandra increases tacrolimus levels similarly in both expressors and non-expressors of CYP3A5, while other studies suggest it does so to a greater degree in CYP3A5 expressors than non-expressors. Animal research suggests that the greatest increase in tacrolimus levels occurs when schisandra is taken either concomitantly or up to 2 hours before tacrolimus, and clinical and observational research in humans suggests that schisandra may increase whole blood levels of tacrolimus and decrease clearance of tacrolimus in a dose-dependent manner.

Likelihood Probable Evidence B
Talinolol

Schisandra can increase the levels and clinical effects of talinolol.
A small pharmacokinetic study in healthy volunteers shows that taking schisandra extract 300 mg twice daily for 14 days with a single dose of talinolol 100 mg on day 14 increases the peak talinolol level by 51% and the overall exposure to talinolol by 47%. This effect is thought to be due to the possible inhibition of cytochrome P450 3A4 and P-glycoprotein by schisandra. tly.

Likelihood Probable Evidence B
Voriconazole (Vfend)

Theoretically, schisandra might increase the levels and clinical effects of voriconazole.
Animal research shows that oral schisandra given daily for 1 or 14 days increases levels of intravenously administered voriconazole, a cytochrome P450 (CYP) 2C19 substrate. This effect is thought to be due to inhibition of CYP2C19 by schisandra. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, schisandra might decrease the levels and clinical effects of warfarin.
Animal research suggests that oral schisandra extract, given daily for 6 days, reduces levels of intravenously administered warfarin. This effect might be due to the induction of cytochrome P450 (CYP) 2C9 metabolism by schisandra. However, this interaction has not been reported in humans.

Fermented Maca by New Chapter: Common Questions

Does Fermented Maca by New Chapter interact with any medications?
Yes. Based on its ingredients, Fermented Maca has a known interaction with 803 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Fermented Maca contains 3 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 this while pregnant?
No. Maca should be avoided because there isn't enough safety data in supplement amounts during pregnancy, and schisandra is possibly unsafe in pregnancy. Talk with your doctor or pharmacist before taking any supplement while pregnant.
Can I take this while breastfeeding?
There isn't enough reliable information about maca or schisandra safety while breastfeeding, so both should be avoided. Cardamom is likely safe in food amounts while breastfeeding, but the other two ingredients lack the data to recommend it. Check with your doctor or pharmacist for personalized advice.
What does maca do?
Maca has been studied for amenorrhea (absent periods), anemia, sexual dysfunction, athletic performance, and bone health, but the evidence is not yet strong enough to say whether it works for any of these. If you're considering it for a specific reason, your doctor or pharmacist can discuss what the research currently shows.
What are the most common side effects?
Schisandra may cause decreased appetite, heartburn, stomach upset, or hives in some people. Raw maca can cause stomach pain. Cardamom is generally well tolerated, though skin reactions have been reported rarely.
Does this product have any fillers?
Yes. It contains inactive ingredients including organic brown rice, maltodextrin, organic gum acacia, a proprietary ferment media, silicon dioxide, lac resin, and carnauba wax—which serve as fillers, binders, and processing aids.
What is schisandra and why is it in here?
Schisandra is an herb that has been studied for asthma, athletic performance, cough, diabetes, diarrhea, and hepatitis, but the evidence is not yet sufficient to rate it for any of these uses. Manufacturers include it for potential adaptogenic (stress-supporting) properties, though the data are not yet established in our database.
