Maca powder has 325 kcal per 100 g with 14 g protein. Traditionally used in Andean medicine for energy and vitality. Current clinical evidence for performance benefits in athletes is limited. The carb content (71 g per 100 g) is worth tracking at larger doses.
How should I track Maca powder?
Maca powder is high in iron. Supplement tracking comes down to two things: measuring the supplement itself and logging everything around it. For powders like Maca powder, a kitchen scale beats a scoop — scoops typically deliver 10–20% more than the stated serving (Almiron-Roig et al., Appetite 2013, found portion errors of 50–200% for dense foods). For capsules and tablets, count-based tracking is simpler but still matters at multiple daily doses. The real tracking trap is what you mix supplements with — milk, fruit, or nut butter can turn a 30-calorie serving into a 400-calorie shake. Log each ingredient separately for an accurate total.
