The stress-response ingredient, not the hormone ingredient.
Ashwagandha has deep roots in Ayurvedic tradition and is classified as an adaptogen, a category of herbs studied for helping the body handle stress more efficiently.
Its role here is indirect: chronic stress can drag down energy, so ashwagandha's job is buffering that, rather than acting on hormone levels or circulation directly.
It's one piece of the six-ingredient formula, not a stand-alone claim.
