Muira puama has a long Amazonian history and two small 1990s studies that every seller quotes. Here is what those studies actually did, why they are weak, and what a fair label claim looks like.
The Plant
Muira puama is the root and stem of Ptychopetalum olacoides, a small Amazonian tree. Its Portuguese name translates as potency wood. Indigenous communities and later Brazilian herbalists used it as a tonic for fatigue, nervous exhaustion and sexual weakness, typically as a decoction or alcohol tincture, since its active compounds are poorly extracted by water alone.
The Two Studies Everyone Quotes
In 1990 and 1994, a Paris clinic reported open-label studies in which men with low desire or erectile difficulty took muira puama extract for two weeks; roughly 60% reported improved desire and about half reported improved function. Both studies lacked a placebo group, were not blinded and were never published in peer-reviewed journals with full methods. A 2000 study of a muira puama and ginkgo combination in women showed similar self-reported improvements, with the same limitations.

Rodent studies suggest muira puama has adaptogenic, antioxidant and nootropic effects and may influence nitric oxide signalling. These are useful hypotheses and nothing more. No randomised, placebo-controlled human trial of muira puama for energy, stamina or sexual function has been published in the past three decades.
A Fair Claim
A fair description is 'traditional Amazonian tonic with preliminary open-label reports and no controlled trials'. It is reasonable as a supportive ingredient in a men's formula; it is not reasonable to call it proven, and any page that does is overstating the evidence.
Where Soda Boost Fits
Soda Boost names Muira Puama as one of its two Brazilian botanicals. Our review page quotes the open-label studies with their limitations rather than presenting them as proof, and notes the amount is not printed.
