Maca Root
A Peruvian root vegetable eaten as a food for centuries, with a modest research record that works in an interesting way.
Why Maca Root Is in JellyBlue
Lepidium meyenii. A Peruvian root vegetable eaten as a food for centuries, with a modest research record on energy, mood and sexual function that appears to work independently of testosterone. This page covers what it is, where its research genuinely sits, its role in the formula and the cautions attached to it.
The JellyBlue amounts are not published — and the format makes that matter
All six ingredients are named. Not one amount is published anywhere, while the source simultaneously describes "optimal therapeutic doses" and "clinically-informed dosing". Those two things cannot both be checked.
In a gummy this matters more than it would in a capsule. A gummy is mostly gelling agent, sweetener and flavouring, and a typical one weighs only a few grams in total, leaving a small fraction for actives. The research doses for several of these ingredients are large. L-arginine trials commonly use several grams per day. Maca studies often use 1.5–3 g. Ashwagandha trials typically use 300–600 mg of extract, and tongkat ali 200–400 mg.
Adding those up exceeds what one gummy can plausibly hold. That does not mean the product contains nothing useful — but it does mean the claim of therapeutic dosing across all six ingredients in a single daily gummy is difficult to credit, and impossible to verify while no figures are published.
What Maca Root in JellyBlue Is
Maca is Lepidium meyenii, a root vegetable in the brassica family — a relative of turnips and radishes — grown at high altitude in the Peruvian Andes.
It is genuinely a food. Andean populations have eaten it for centuries, dried and powdered, in quantities far larger than any supplement provides. That long dietary history is a meaningful part of its safety record.
Maca comes in yellow, red and black varieties, which appear to differ somewhat in effect. The brand does not state which is used.
The Research Context Behind Maca in JellyBlue
Maca has a small but real human research base, and one genuinely interesting finding.
Sexual function and libido. Several small randomised trials have reported improvements in self-reported sexual desire in men, typically over eight to twelve weeks. A systematic review concluded there is limited but suggestive evidence here.
The interesting part: these effects appear to occur without measurable changes in testosterone or other sex hormones. Trials that measured hormones generally found them unchanged. Whatever maca does, it does not appear to work hormonally — which is a useful corrective to marketing that lumps it in with testosterone boosters.
Energy and mood. Some trials report improvements in subjective energy and mood, and some work in postmenopausal women has looked at anxiety and depression scores.
The limitations. Trials are small, often short, and heterogeneous in the preparations used. Doses in studies are typically 1.5–3 g of maca powder daily — a substantial quantity, and one that immediately raises the format question for a gummy.
Why Maca Root Is Included in JellyBlue
It supports the energy and vitality side of the formula, and it is a sensible inclusion: a food-history ingredient with a good safety record and some genuine human evidence for exactly the kind of subjective outcomes this product targets.
The dose issue is at its most pointed here. Studies use grams. Even a generous share of a single gummy is a fraction of that.
Safety Considerations for Maca in JellyBlue
Maca has one of the better safety profiles in this formula, largely because it is a food with centuries of dietary use behind it.
Generally well tolerated. Reported effects are mild and mostly digestive — bloating, gas or stomach upset in some people.
Considerations worth knowing:
- It is a brassica, and raw brassicas contain goitrogens that can affect thyroid function in people with iodine deficiency or existing thyroid conditions. Traditional preparation involves cooking, which reduces this; supplement processing varies.
- Speak to a doctor if you have a thyroid condition, particularly since ashwagandha in the same formula also affects thyroid hormones.
- Hormone-sensitive conditions warrant medical advice before use, even though maca does not appear to act hormonally.
How to read the research on this JellyBlue page
The studies described here examined individual ingredients, on their own, at doses the researchers chose. That research explains why an ingredient is a reasonable thing to include in a formula.
It does not demonstrate that JellyBlue produces the same outcomes. No clinical trial of this finished gummy has been published, and the amounts it contains are not disclosed, so ingredient research cannot be transferred to the product.
JellyBlue safety: the interactions worth checking first
This formula is not a neutral multivitamin. Several ingredients affect blood vessels, blood pressure or hormones, and the source's own comparison table claims "no side effects", which is not something any supplement can support.
- If you take nitrates or nitric-oxide-donating heart medication, speak to a doctor before using this product. L-arginine widens blood vessels, and epimedium's icariin has vasodilatory activity in laboratory work. Combining vessel-dilating substances with nitrates can cause a dangerous drop in blood pressure.
- The same applies to blood pressure medication and to prescription erectile dysfunction medicines, for the same reason.
- Ashwagandha has case reports of liver injury, can raise thyroid hormone levels, may add to sedatives, and is generally advised against in autoimmune thyroid conditions. Stop and seek advice if you notice jaundice, dark urine or unusual fatigue.
- Grape seed extract and L-arginine may both affect bleeding, so mention them if you take anticoagulants or have surgery planned.
- Tongkat ali is not advised in hormone-sensitive conditions, and supplement-market samples have historically had quality and contamination problems, so sourcing matters.
- L-arginine may trigger recurrences in people prone to cold sores or genital herpes, and should be used cautiously after a recent heart attack.
- These are gummies. They contain sugar or sweeteners, which is worth knowing if you manage blood glucose, and they need keeping away from children, for whom this product is not intended.
This is an adult men's product. Speak to a doctor or pharmacist before starting it, particularly alongside any prescription — advice the brand gives as well.

Tongkat Ali
A Southeast Asian root used traditionally as a male tonic, and the ingredient with the most direct research on testosterone and stress hormones — though the trials are small.
Stress and sleepAshwagandha
The best-evidenced ingredient in the formula, with reasonably consistent trials on stress, cortisol and sleep quality — and a safety consideration worth knowing about.
Circulation supportHorny Goat Weed
A traditional Chinese herb containing icariin. Its laboratory pharmacology is the reason this ingredient needs a genuine interaction warning rather than a marketing line.
Nitric oxide precursorL-Arginine HCl
An amino acid the body converts into nitric oxide, which widens blood vessels. Well researched — and studied at doses measured in grams, which matters in a gummy.
