Maca Root Powder

Single-ingredient maca root reference formula at 1,000 mg per serving, developed as a two-capsule serving or a powder.

Maca is a reference formula for brands building a single-ingredient Andean root product at a default amount of 1,000 mg of maca per serving. Maca is the only active ingredient, so the development work centers on the raw material form (dried root powder or a concentrated extract), the bulky fill of a root powder, and the capsule count or stick weight that follows from it.

Capsule is the lead format, with the 1,000 mg serving built as two 500 mg capsules as on the reference label, and a powder version serves brands that sell a drink mix. Root powders and standardized extracts are different raw materials, and the reference labels include both; this page uses the root powder as the default and lists the extract as an alternative.

Ingredient Composition

IngredientPer ServingRaw Material FormAlternative Form (same amount of active)
Maca1000 mg (default amount)Maca root powder, dried and milled, with the root color (yellow, red or black) and any gelatinization set in the specification; 1,000 mg maca powder per serving, for example the Maca Root Powder gradeMaca Extract 0.6–1% Total Macamides as a separate specification at a smaller fill weight, or general Maca Extract Powder

Amounts are stated as mg of maca raw material, not of marker compounds. A root powder and an extract at the same milligram amount are not equivalent: the extract concentrates the marker compounds, and a switch between them changes the dose of those compounds and the fill weight.

Intended Benefits & Formula Rationale

This formula is designed for products positioned around botanical energy and hormonal-balance nutrition. Maca is included as the single active so that the raw material form, the amount and the excipient system can be set without interaction with other actives.

Intended Benefit DirectionKey IngredientsFormulation Rationale
Traditional botanical nutritionMacaIncluded because maca, an Andean plant of the brassica family, has been used for centuries as an adaptogenic plant to manage anemia, infertility and female hormone balance [1]. Evidence: Referenced
Menopausal nutrition studiesMacaA systematic review of four randomized trials found favorable effects of maca on menopausal symptom scores, and concluded that the evidence is limited because the trials are few and small [1]. Evidence: Mixed
Semen quality studiesMacaA meta-analysis of five randomized trials found unclear effects of maca on semen quality, with no significant effect on sperm concentration and a number of trials too small for firm conclusions [2]. Evidence: Contested

The amount is one stated tier. Because the two reviews call their evidence limited or unclear, amount, claims and target market are brand decisions reviewed for each sales market.

Available Formats

The maca reference formula is built for a two-capsule version and a powder version; counts per serving are design choices that the brand can adjust.

Powder1 stick pack1000 mg30 stick packsDiluent, sweetener, flavor, anti-caking agentDrink mix; the earthy taste needs masking

Raw Material Input & Fill (Design Estimate)

Design estimates. The input is the labeled root powder weight at an assumed 100% assay of the powder as purchased, so 1000 mg of maca powder per serving is used as the input.

FormatRaw Material Input per UnitDesign FillBalance for ExcipientsVerification Before Scale-Up
Capsule500 mg per capsule (2 per serving)530 mg per capsule30 mgBulk density, fill weight variation, flow, moisture
Powder1000 mg3500 mg per stick2500 mgDispersion in water, earthy taste, caking

Tablet, softgel and gummy versions are separate projects, because a bulky root powder needs its own matrix and load work in those systems.

Formulation Considerations

Bulky root powder. A root powder has a low bulk density, so 1000 mg takes two full capsules and little room is left for a flow aid. Density and flow are measured on the received lot before the capsule size and fill weight are fixed.
Moisture and microbial load. Root powders carry moisture and a natural microbial load, so drying, milling, microbial limits and a barrier bottle are part of the specification.
Root color and processing. Yellow, red and black maca roots, and raw or gelatinized powders, differ in composition and taste. The specification names the type and the processing, and a switch between them is a new product.
Evidence and tier. The review in [1] calls its evidence limited and the meta-analysis in [2] reports unclear effects, so claims on a finished product are reviewed for each sales market. The amount tier and the dose limit for each sales market are checked before a product is developed.

Customization Options

Brands adjust the amount per serving, the raw material form, the root type and the format.
