Maca (Lepidium meyenii) is a cruciferous root — botanically closer to a radish than a herb — cultivated in the Peruvian Andes above 4,000 metres. Few crops survive that environment, which is partly why it became a dietary staple there.
It has been grown and eaten in the region for centuries, valued specifically for supporting energy and physical endurance under genuinely punishing conditions. That traditional record is real and long, which is more than can be said for many ingredients in this category.
Interest centres on maca's glucosinolates and macamides, compound families not widely found elsewhere. Research areas include energy and fatigue measures, endurance markers and mood.
Being straight about the state of the evidence: studies are generally small, methodologies vary, and results are not consistent enough to call anything settled.
Catuaba refers to the bark of several trees, most commonly from the Erythroxylum and Trichilia genera. That botanical ambiguity is worth knowing: “Catuaba” on a label does not always denote a single species, which complicates comparing products.
In Brazil it is among the most widely consumed herbal tonics, traditionally taken as a bark infusion to support energy and general well-being. Its published literature is primarily preclinical.
In a men's blend, both typically occupy the stamina and endurance slot rather than the headline position. That is an honest placement, and it is how Jellysforce uses them: sustained physical output through a day, rather than an acute pre-workout effect.
A formula that built its entire pitch on either would be overreaching. One that includes them as traditional components while resting stronger claims on better-supported ingredients is doing something reasonable.
