HelloPharmacist Scorecard of Gelatinized Peruvian Maca Powder by Gaia Herbs

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 30, 2026

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This powder contains one active ingredient: organic maca. Maca is a root vegetable from Peru that's been used as a food for centuries.

The gelatinized form means it's been heat-treated to make it easier to digest and absorb. There are no inactive ingredients listed.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: support healthy energy and stamina for athletes.
  • We looked for evidence on: Athletic performance, Fatigue, Chronic fatigue syndrome (CFS), endurance, physical performance, vitality.
  • The closest evidence on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Fatigue.

The evidence on maca for most uses is insufficient to rate. That includes amenorrhea (missed periods), anemia, antidepressant-induced sexual dysfunction, athletic performance, and osteoporosis.

The data we hold doesn't establish that maca works reliably for any of these. If you're considering it for a specific health concern, talk with your doctor or pharmacist about what the science actually shows and whether it's right for you.

The evidence, ingredient by ingredient Black Psyllium Maca

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • 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 supplement safety hasn't been studied long term — so we don't have a lot of data on safety at supplement doses over time. The safety data we hold advises against use during pregnancy and breastfeeding because there isn't enough information.

One adverse effect to note: fresh, uncooked maca may cause stomach pain, though this product is gelatinized (heat-treated), which should reduce that risk.

Side effects, ingredient by ingredient Black Psyllium Maca

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

Why this rating?
  • 1 of the 2 matched ingredients can interact with medications — Black Psyllium.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications; lithium.
  • For scale: 2,026 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.

The bottom line

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

If you've used maca as a food and tolerated it well, the gelatinized powder is likely safe short term. But the evidence for its effectiveness on the conditions it's marketed for is not established.

Pregnancy and breastfeeding are not advised based on the safety data. Talk with your doctor or pharmacist before starting, especially if you're pregnant, breastfeeding, or taking medications.

Each ingredient & the kinds of drugs it affects

For each ingredient in Gelatinized Peruvian Maca Powder with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

Dietary Fiber7 drug types · 2,025 drugs

Carbamazepine (Tegretol)

Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Lithium

Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Metformin (Glucophage)

Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.

Likelihood Possible Evidence D
Olanzapine (Zyprexa)

Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.

Likelihood Unlikely Evidence B
Ethinyl Estradiol

Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.

Gelatinized Peruvian Maca Powder by Gaia Herbs: Common Questions

Does Gelatinized Peruvian Maca Powder by Gaia Herbs interact with any medications?
Yes. Based on its ingredients, Gelatinized Peruvian Maca Powder has a known interaction with 2,025 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Gelatinized Peruvian Maca Powder contains 2 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.
Is maca safe during pregnancy or breastfeeding?
The safety data advises against it. There isn't enough reliable information on safety in supplement amounts during pregnancy or breastfeeding, so it's best avoided during these times. Talk with your doctor or pharmacist for personalized guidance.
Does this product contain fillers or other inactive ingredients?
No inactive ingredients are listed for this product — it's just the maca powder itself.
What does maca actually do?
The evidence on maca for the uses it's marketed for — amenorrhea, anemia, sexual dysfunction, athletic performance, and osteoporosis — is insufficient to rate. That means the science doesn't yet establish that it works reliably for any of these conditions.
Can this cause stomach upset?
Fresh, uncooked maca can cause stomach pain, but this product is gelatinized (heat-treated), which makes it easier to digest and should reduce that risk. That said, if you do experience stomach upset, stop and talk with your pharmacist.
Is maca safe to take long term?
Maca is generally well tolerated as a food, but supplement safety at supplement doses hasn't been studied long term. We don't have reliable data on safety over extended use, so talk with your doctor or pharmacist about how long you plan to use it.
