Maca Powder vs Maca Root Extract: Which Is Better for Men?

By Blue Power Research Team · 14 May 2026 · 8 min read

Walk into any health shop in the UK and you’ll find maca in at least three forms: raw powder, gelatinised powder, and concentrated extract capsules. The prices vary wildly — from £8 for a bag of powder to £30+ for an extract supplement. But here’s the question nobody answers clearly: is maca powder or maca root extract actually better for men’s health?

The answer depends on what “better” means to you. If it means the highest concentration of bioactive compounds per milligram, extract wins. If it means the cheapest way to get maca into your body, powder wins. But if it means clinical evidence for the outcomes men actually care about — libido, energy, sexual function — the picture is more nuanced than either camp admits.

TL;DR — Maca Powder vs Extract for Men

Extract concentrates bioactive macamides at 4:1 to 10:1 ratios — meaning 500mg of extract ≈ 2,000–5,000mg of raw powder in active compounds
Powder delivers the full-spectrum root but requires 1,500–3,000mg/day for clinical effect (Gonzales et al., 2002)
The strongest extract RCT (Zenico et al., 2009) used 2,400mg/day of dry extract in 50 men with mild erectile dysfunction — IIEF-5 improved significantly vs placebo (+1.6 vs +0.5, p<0.001)
Maca has no EFSA-approved health claims in the UK — all evidence comes from published clinical trials
For men over 40: extract is more practical and better supported by recent clinical data; powder suits budget or smoothie use

What’s the Actual Difference?

Maca Powder

Dried & ground whole root

Maca Extract

Concentrated active compounds

Maca powder is exactly what it sounds like: the whole maca root (Lepidium meyenii), dried and ground into a fine powder. It contains everything in the root — fibre, starch, protein, vitamins, minerals, and the bioactive compounds (macamides, macaenes, and glucosinolates) that drive maca’s effects. The downside: bioactives make up only a small fraction of total weight. You need a large dose (typically 1,500–3,000mg) to obtain a meaningful amount of the compounds that matter.

Maca root extract uses water, ethanol, or solvent extraction to concentrate the bioactive compounds. A 4:1 extract means 4kg of raw root was used to produce 1kg of extract — so 500mg of a 4:1 extract contains roughly the same macamide content as 2,000mg of powder. A 10:1 extract concentrates this further still. The result: fewer capsules, higher potency per dose, and better standardisation of the active ingredients.

There’s also a middle option: gelatinised maca powder. This is powder that has been heated to break down starch and improve digestibility, but it is not concentrated. It’s easier on the stomach than raw powder but does not offer the potency advantage of a true extract.

Head-to-Head Comparison

Factor	Maca Powder	Maca Root Extract
Form	Dried, ground whole root	Concentrated (4:1 to 10:1) Best potency
Clinical dose	1,500–3,000mg/day	450–2,400mg/day
Capsules/day	3–6 capsules (500mg each)	1–2 capsules Best convenience
Macamide concentration	∼0.01–0.02% of dry weight	∼0.1–0.5% (standardised)
Batch consistency	Variable — up to 40-fold variation reported	Standardised to active compounds Best consistency
Full-spectrum nutrients	Yes — fibre, minerals, protein retained Best whole-food	Partial — focused on bioactives
Digestibility	Can cause bloating (raw starch)	Generally well tolerated
Primary RCT evidence	Gonzales 2002 (1,500–3,000mg)	Zenico 2009 (2,400mg dry extract)
UK price (30-day supply)	£8–15 Best value	£15–30
Best for	Smoothies, cooking, budget users	Capsule supplements, targeted dosing

A 2017 analysis of commercial maca products found macamide content varying up to 40-fold — from 69 to 2,738 micrograms per gram (International Journal of Food Properties, 2017). This enormous batch-to-batch variation is precisely why standardised extracts matter: you know what you’re getting in every capsule, whereas raw powder offers no such guarantee.

What Does the Clinical Evidence Show?

The Landmark Powder Study: Gonzales 2002

The most cited maca study used powder. Gonzales et al. (2002) gave 57 men either 1,500mg or 3,000mg of maca powder daily for 12 weeks. Sexual desire increased significantly from week 8 onward in both dose groups, but — crucially — serum testosterone and oestradiol levels were completely unchanged (Gonzales et al., Andrologia, 2002). This was a landmark finding: maca improves libido through a mechanism that does not involve testosterone.

Trial context. This figure comes from a controlled trial at the dose used in that trial — 1,500–3,000 mg/day of maca powder — which differs from the 50 mg of maca contained in one Blue Power tablet. We cite the study to describe the published evidence base. We do not transfer the trial outcome to Blue Power as a product claim.

The Extract Evidence: Zenico 2009

The strongest RCT specifically using extract is Zenico et al. (2009). In a 12-week double-blind, placebo-controlled trial of 50 men with mild erectile dysfunction, 2,400mg/day of maca dry extract significantly improved IIEF-5 scores compared to placebo (+1.6 vs +0.5, p<0.001) and subjective well-being (Zenico et al., Andrologia, 2009). This is the clearest published evidence on the extract form and men’s sexual function at the dose studied.

Trial context. This figure comes from a controlled trial at the dose used in that trial — 2,400 mg/day of maca dry extract in men with mild erectile dysfunction — which differs from the 50 mg of maca contained in one Blue Power tablet. We cite the study to describe the published evidence base. We do not transfer the trial outcome to Blue Power as a product claim.

“In our 12-week double-blind study, men with mild erectile dysfunction taking 2,400mg/day of maca dry extract showed statistically significant improvement in IIEF-5 scores and subjective well-being versus placebo — confirming that the concentrated extract form is clinically effective at the dose studied.”

Age-Related Symptoms: Shin 2023

A 2023 RCT in men with late-onset hypogonadism symptoms — the clinical term for age-related testosterone decline — found that maca significantly improved IIEF scores by +3.2 points and reduced ADAM (Androgen Deficiency in Aging Males) symptom prevalence from 73% to 51% (Shin BC et al., World Journal of Men’s Health, 2023). This population is directly relevant to UK men over 40 researching supplements.

Trial context. This figure comes from a controlled trial at the maca dose used in that trial, which differs from the 50 mg of maca contained in one Blue Power tablet. We cite the study to describe the published evidence base. We do not transfer the trial outcome to Blue Power as a product claim.

Comprehensive Review: Al-Dujaili 2024

A 2024 review in Frontiers in Pharmacology analysed 57 preclinical and clinical studies on maca — 55 out of 57 (96.5%) reported positive effects on sexual function, energy, or mood (Al-Dujaili et al., 2024). That’s an unusually consistent published evidence base for a herbal supplement.

Trial context. This figure summarises outcomes across studies that used a range of maca doses, generally far higher than the 50 mg of maca contained in one Blue Power tablet. We cite the review to describe the published evidence base. We do not transfer these findings to Blue Power as a product claim.

Sperm Quality: Gonzales 2001

An earlier study by the same research group found that 1,500–3,000mg/day of maca powder for 4 months significantly increased sperm count and motility without affecting hormone levels (Gonzales et al., Asian Journal of Andrology, 2001). For men researching fertility alongside libido, this is relevant additional evidence — though this study used powder, not extract.

Important caveat: No study has directly compared maca powder vs maca extract head-to-head in the same trial. We are comparing across different studies, which introduces variability in populations, doses, and outcome measures. That said, extract-specific evidence (Zenico 2009) demonstrates significant improvements using concentrated dry extract at a clinically practical dose.

The Bioactive Compounds That Matter

Maca’s effects are not driven by a single molecule — they come from a group of unique compounds found almost exclusively in this Peruvian root:

Macamides — Fatty acid derivatives unique to maca. These interact with the endocannabinoid system and are considered the primary drivers of maca’s effects on libido and mood. Concentration increases significantly with extraction (Esparza et al., Molecules, 2015).
Macaenes — Unsaturated fatty acids that work synergistically with macamides. Early animal studies linked them to improved sexual behaviour.
Glucosinolates — Compounds shared with cruciferous vegetables (broccoli, kale). May support detoxification pathways. Higher in raw and gelatinised powder than in some extraction processes.
Alkaloids — Present in trace amounts. The specific alkaloids in maca (macaridine) are under-researched but may contribute to its adaptogenic properties.

Source: Estimated from published macamide analyses (Esparza et al., Molecules, 2015; McCollom et al., Phytochem Anal, 2005). Actual values vary by cultivar, origin, and extraction method.

Macamides are the compounds most strongly associated with maca’s clinical effects in men. A 2017 analysis found macamide content in commercial maca products varies up to 40-fold — from 69 to 2,738 micrograms per gram (International Journal of Food Properties, 2017). This is why standardised extracts offer a clear advantage: you know what you’re getting in every batch, whereas raw powder offers no such guarantee.

EFSA Status and UK Regulatory Position

Important for UK consumers: Maca has no EFSA-approved health claims in the UK or EU. In 2010, the European Commission placed 1,548 botanical health claims — including maca — “on hold” pending further review (EFSA, 2011). They remain unresolved as of 2026. This means maca claims are neither formally approved nor formally rejected — a regulatory grey area. Any UK product claiming maca “is associated with measured changes in testosterone in trial conditions” or “cures erectile dysfunction” is making an illegal health claim under current UK law.

This does not mean maca does not work — 96.5% of published studies report positive effects. It means the formal EFSA Article 13 evaluation has not been completed. The clinical evidence from published RCTs exists independently of this regulatory framework. When choosing a maca supplement, look for brands that cite specific studies rather than making unauthorised health claims — it is a marker of transparency.

Which Form Should You Choose?

Choose Maca Powder If:

You want to add maca to smoothies, porridge, or baking
Budget is the primary concern (£8–15 for a month’s supply)
You prefer whole-food supplements with the full nutrient profile intact
You are comfortable taking 3–6 capsules daily or mixing powder into food
You want the glucosinolate content that some extraction processes reduce

Choose Maca Extract If:

You want the highest concentration of macamides per dose
Convenience matters — 1–2 capsules vs 3–6 daily
You are taking maca as part of a multi-ingredient men’s supplement where space per ingredient is limited
You want standardised dosing — same active compound levels in every batch
The strongest extract-specific RCT (Zenico 2009) used dry extract and showed significant improvements in erectile function

Dosage timing note: Both forms require consistent daily use for best results. Clinical trials saw effects emerge at 8 weeks (libido, Gonzales 2002) and 12 weeks (erectile function, Zenico 2009). Maca is not a fast-acting compound — allow at least 6–8 weeks before assessing whether it is working for you.

How to Spot a Quality Maca Supplement

Whether you choose powder or extract, these markers identify genuine quality:

Extraction ratio stated: A quality extract specifies its concentration (e.g., 4:1, 10:1). If it simply says “maca extract” with no ratio, you cannot assess potency.
Species identified: Lepidium meyenii (or Lepidium peruvianum) should appear on the label. “Maca blend” is vague and unverifiable.
Origin stated: Premium maca comes from the Junin plateau in Peru, grown at 4,000m+ altitude. Higher-altitude maca has been shown to contain more bioactive compounds.
No illegal health claims: Any UK-sold maca product claiming to “treat ED” or “is associated with measured changes in testosterone in trial conditions” is in breach of MHRA/EFSA regulations. Honest brands cite clinical studies, not marketing slogans.
GMP certification: Good Manufacturing Practice ensures consistent quality and absence of contamination. Look for UK or EU GMP certification marks.

The 40-fold variation in macamide content across commercial maca products (Int J Food Properties, 2017) means that choosing the cheapest product often delivers far less active material than the label implies. Standardised extracts with a stated ratio and macamide percentage are the only way to know you’re getting what you paid for.

Blue Power and Maca Root Extract

Why Blue Power Uses Maca Root Extract

Blue Power contains Maca Root Extract — not powder. In a multi-ingredient formula with 8 components, extract is the practical choice: it delivers concentrated macamides in a compact form without requiring extra capsules. Here is how it sits alongside the other ingredients:

Maca Root Extract — included for its long history of traditional use in the Peruvian highlands.
Tongkat Ali — included for traditional use; its proposed mechanisms are described in published research.
Shilajit — included for traditional use; its proposed mechanisms are described in published research.
Zinc — contributes to the maintenance of normal testosterone levels in the blood (EFSA authorised, Regulation 432/2012).
L-Arginine — included for traditional use; its proposed mechanisms are described in published research.

Authorised health claims on the Blue Power label apply to Zinc and Vitamin C only. The other six ingredients — including Maca Root Extract — are included for their long history of traditional use and the published evidence base described in this article; none is the basis of an authorised health claim, and the trial findings cited above cannot be transferred to Blue Power as product claims.

Blue Power — Contains Maca Root Extract

One daily tablet. 8 ingredients with clearly listed doses: Maca Root Extract, Tongkat Ali, Shilajit, Zinc, Korean Ginseng, L-Arginine, Horny Goat Weed and Vitamin C. GMP certified, UK made, no proprietary blends. Authorised health claims on the label apply to Zinc and Vitamin C only.

Frequently Asked Questions

Is maca powder or maca root extract better?

On the published evidence, maca root extract is the more practical form for capsule supplements. Extract concentrates the bioactive macamides and macaenes at 4–10× the levels found in raw powder, meaning more active compounds per capsule. The strongest extract-specific RCT (Zenico et al., 2009) used dry extract at 2,400mg/day in men with mild ED and reported improvement in IIEF-5 scores versus placebo (+1.6 vs +0.5, p<0.001). That figure applies at the trial dose used in that study, which differs from the 50 mg of maca in one Blue Power tablet; it is cited as published research, not as a product claim. Powder is a reasonable budget option but requires a much higher daily dose (1,500–3,000mg) and offers less consistency.

What does the published research on maca and testosterone show?

Multiple clinical trials — including the landmark Gonzales 2002 RCT — have consistently found that maca does not change serum testosterone or oestradiol levels. In the published research, maca’s effects on libido, energy and sexual function appear to work through independent pathways, likely involving the central nervous system and endocannabinoid receptors. This describes the published evidence base and is not a product claim. Authorised health claims on the Blue Power label apply to Zinc and Vitamin C only.

What is gelatinised maca?

Gelatinised maca is powder that has been heat-processed to remove starch and improve digestibility. It is not more concentrated than regular powder — it simply has the indigestible starch broken down, making it gentler on the stomach. Think of it as a middle ground: easier to digest than raw powder, but without the concentrated potency of an extract. It is a good option if raw powder causes bloating but you prefer a whole-food supplement form.

How much maca should I take per day?

The dose studied depends on the form. Clinical trials used 1,500–3,000mg/day for powder (Gonzales 2002) and 2,400mg/day for dry extract (Zenico 2009). These are trial doses, reported here as published research; they differ from the 50 mg of maca in one Blue Power tablet and are not the basis of a product claim. In a multi-ingredient formula the maca dose is lower. Trial-measured effects were typically reported after 8–12 weeks of consistent use.

Can I take maca powder and extract together?

You can, but there is no clinical evidence that combining both forms provides additional benefit beyond what either delivers alone. You would be obtaining the same bioactive compounds from two different sources. Most men are better served choosing one form and using it consistently for at least 8–12 weeks to assess its effects before making any changes.

Is maca safe for men over 40?

Maca has a strong safety profile across clinical trials. The Gonzales studies (up to 3,000mg/day for 12 weeks) and the Zenico 2009 study (2,400mg dry extract for 12 weeks) reported no serious adverse events. Maca has been consumed as a food staple in Peru for thousands of years. However, men taking prescription medication — particularly for blood pressure, thyroid conditions, or hormone-sensitive conditions — should consult their GP before supplementing.

The Bottom Line

Maca works — the clinical evidence for its effects on libido, sexual function, and energy in men is consistent across multiple RCTs spanning more than two decades. The question is not whether to take maca, but which form delivers the best value.

For men over 40 seeking targeted support, extract wins on practicality and potency. It concentrates the macamides that drive maca’s effects, requires fewer capsules, and was the form used in the strongest extract-specific RCT (Zenico 2009). Powder remains a solid budget option — especially if you enjoy adding it to smoothies — but requires higher doses and offers less batch consistency.

Either way, give maca at least 8 weeks before judging its effects. Hormonal and neuroendocrine pathways do not respond overnight.
