HelloPharmacist Scorecard of Maca Velvet by Maca Magic

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 Aug 20, 2026

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 0 of its 5 active ingredients.

Maca Velvet contains 5 active ingredients: maca root, deer velvet, Tongkat Ali, plus cane alcohol and organic vegetable glycerin as the liquid base. Maca is a plant root used traditionally as a food and supplement.

Deer velvet is the velvety tissue that covers growing antlers. Tongkat Ali is a root extract sometimes called Eurycoma longifolia.

Vegetable glycerin serves as a sweetener and preservative in the liquid formula.

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: sexual function, energy, and male fertility support.
  • We looked for evidence on: Erectile dysfunction (ED), Sexual desire, Male Infertility, Fatigue, Age-related testosterone deficiency, Libido — and 2 related terms.
  • The strongest evidence on file: Eurycoma Longifolia is rated "Possibly Effective" for Sexual desire (Natural Medicines).
  • Also on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Fatigue, Sexual desire, Age-related testosterone deficiency, and more.
  • Also on file: Deer Velvet is rated "Insufficient Reliable Evidence To Rate" for Erectile dysfunction (ED).

The evidence for maca in this product doesn't yet support claims for amenorrhea (missed periods), anemia, sexual dysfunction, athletic performance, or bone health—we simply don't have enough reliable research. Vegetable glycerin is likely effective for constipation and possibly effective for ichthyosis (a skin condition), though these aren't common reasons someone would take a product like this one.

Tongkat Ali is possibly effective for sexual desire, but the evidence on athletic performance is weak. Deer velvet and the other uses listed lack solid evidence.

The evidence, ingredient by ingredient Maca Glycerol Deer Velvet Eurycoma Longifolia

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 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Maca and Tongkat Ali are generally well tolerated in short-term studies, but long-term safety as supplements hasn't been thoroughly studied. Maca can cause stomach pain if consumed fresh and uncooked, and both maca and Tongkat Ali should be avoided in pregnancy and while breastfeeding because safety data is insufficient.

Vegetable glycerin in larger medicinal doses can cause bloating, nausea, vomiting, diarrhea, headache, and dizziness. If Tongkat Ali does raise testosterone levels, it could theoretically bring on acne, insulin resistance, and liver concerns—talk to your doctor if you have a history of these issues.

Side effects, ingredient by ingredient Maca Glycerol Deer Velvet Eurycoma Longifolia

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?
  • 2 of the 4 matched ingredients can interact with medications — Deer Velvet, Eurycoma Longifolia.
  • The most serious interaction on file is rated Moderate.
  • For scale: 268 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.

If you take propranolol (a heart and blood pressure medication), Tongkat Ali may reduce how well it works—this is a Moderate concern. Check with your doctor or pharmacist about any birth control pills, estrogen supplements, testosterone, or any medications your liver breaks down through CYP enzyme pathways before you start this product.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is aimed at sexual function and athletic performance, though evidence for those uses is mixed. If you take propranolol, birth control, estrogen, testosterone, or medications processed by your liver's CYP1A2, CYP2C19, or CYP2A6 pathways, check with your doctor or pharmacist before starting.

Pregnant people and those breastfeeding should avoid it. Have a conversation with your healthcare provider about whether it's right for you.

Tongkat Ali5 drug types · 248 drugs

Propranolol (Inderal)

Eurycoma longifolia can reduce the levels and clinical effects of propranolol.
A small clinical study in healthy persons shows that taking a single dose of a water-based Eurycoma longifolia extract 200 mg, in combination with a single dose of propranolol 80 mg, reduces the propranolol area under the curve (AUC) by 29%, reduces the peak concentration by 42%, and increases time to peak concentration by 86% when compared with control. Since the elimination half-life of propranolol did not change, it seems that Eurycoma longifolia alters the kinetics of propranolol by decreasing its absorption in the gut, and not by altering its metabolism. It is not known if separating administration will prevent this interaction.

Likelihood Probable Evidence A
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, Eurycoma longifolia might increase levels CYP1A2 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP1A2 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2A6 (Cyp2A6) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2A6 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2A6 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2C19 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2C19 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Testosterone

Theoretically, Eurycoma longifolia may further increase levels of testosterone.
A clinical study in aging males with testosterone levels below 300 ng/dL shows that taking a specific water extract of Eurycoma longifolia roots (Physta; Biotropics Malaysia) 100-200 mg daily with breakfast for 12 weeks increases total testosterone levels by 8% to 11% when compared with placebo. It is unclear whether this increase would occur in individuals with normal testosterone levels.

Likelihood Possible Evidence D

Deer Velvet2 drug types · 52 drugs

Contraceptive Drugs

Theoretically, deer velvet might interfere with the effectiveness of contraceptive drugs.
Laboratory research shows that deer velvet contains small quantities of estradiol and testosterone. While clinical research shows that taking deer velvet extract does not raise testosterone levels, estradiol levels were not measured.

Likelihood Unlikely Evidence D
Estrogens

Theoretically, deer velvet might increase the effects and side effects of estrogens.
Laboratory evidence shows that deer velvet contains small quantities of estradiol and testosterone. While clinical research shows that taking deer velvet extract does not raise testosterone levels, estradiol levels were not measured.

Maca Velvet by Maca Magic: Common Questions

Does Maca Velvet by Maca Magic interact with any medications?
Yes. Based on its ingredients, Maca Velvet has a known interaction with 268 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Maca Velvet 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 this if I'm pregnant or breastfeeding?
No. Both maca and Tongkat Ali lack enough safety data in supplement amounts during pregnancy and while breastfeeding, so the safety data advises against it. Talk with your doctor before taking this product if you're pregnant, planning pregnancy, or nursing.
What's deer velvet and why is it in here?
Deer velvet is the soft tissue covering growing antlers. It's used in supplements for wound healing, sexual desire, and aging, though we don't yet have reliable evidence it works for these uses. We hold no study data showing it causes side effects, but long-term safety hasn't been well studied.
Does this actually improve sexual function?
Tongkat Ali is possibly effective for sexual desire, but maca and deer velvet don't have enough reliable evidence yet. If sexual function is your goal, talk with your doctor about what the evidence shows before deciding.
What side effects might I notice?
Maca may cause stomach pain, especially if it's fresh and uncooked. The vegetable glycerin base can cause bloating, nausea, diarrhea, headache, and dizziness in larger amounts. If Tongkat Ali raises testosterone, acne and other hormone-related effects are possible.
How long is it safe to take this?
Short-term use in studies appears well tolerated, but long-term safety as a supplement hasn't been studied carefully. If you're thinking of taking it regularly, talk with your pharmacist or doctor.
Is there anything else in this besides the main ingredients?
This liquid contains cane alcohol and organic vegetable glycerin to deliver the active ingredients, but no other inactive fillers. The glycerin also helps with constipation, though that's not why most people take this product.
