Tongkat Ali
Preliminary studies have examined Tongkat Ali's association with healthy testosterone levels and reduced fatigue. See our full Tongkat Ali deep dive.
Maca Root
Traditionally used as both a food and remedy in Peru, Maca has preliminary research behind its association with energy and mood. See our Maca Root article.
Ashwagandha
Among the more studied adaptogens, with a number of clinical trials examining stress and cortisol. See our Ashwagandha guide.
L-Arginine HCl
Backed by a well-understood biochemical mechanism (nitric oxide production) for supporting circulation. See our L-Arginine article.
Where the science is strongest — and where it's still emerging
L-Arginine's role in circulation via nitric oxide is one of the most well-established mechanisms in the formula. Ingredients like Horny Goat Weed and Tongkat Ali have longer track records of traditional use than of large randomized trials — which is typical for many botanical supplements. You can explore the primary literature yourself via PubMed.
Bottom line
SodaPeak's formula reflects a reasonable, transparent approach to combining traditionally-used botanicals with one well-studied amino acid — not a "miracle" claim, but a defensible ingredient stack. See our overall worth-it review for the full picture.
