Maca is a root crop from the Peruvian Andes and it grows in three colours: yellow, red and black. Yellow is roughly 60 to 70 percent of every harvest, which makes it the cheap one and the default one. Red and black are the scarcer fractions and they are the ones the human work has mostly looked at separately. On the 24 labels we read, 19 print one line that says maca and one milligram number. That number could be entirely yellow root and the label would look identical.
The ones that do mention colour often mention it in the marketing rather than on the panel. We read one bottle whose description explains at length that it contains black, red and yellow roots, while its Supplement Facts print a single 1900 mg line with no split at all. That is not a lie, but it is not information either: you cannot tell whether the black fraction is 900 mg or 90 mg. The panel is where a claim becomes checkable, and the panel is where the colour disappears.
Then there is what the root was grown in, because maca is a root and roots take up what is in the soil around them. Organic is the only word here that carries a legal definition, and 11 of the 24 say organic on the maca line itself. One formula of 24 printed organic on each ingredient line, an amount for each of the three colours, and a black-dominant ratio: 1000 mg black, 250 red, 250 yellow, with black pepper alongside.
Took maca and felt nothing? You may have taken the cheap colour.If the panel says maca and a number, the honest answer is that you do not know what you took. Turn the bottle around and look for three lines with three amounts. If there is one line, assume it is mostly yellow root, because that is what the harvest is mostly made of and what costs the least.
