Sleep support appears among the claims, and the ingredient list does not connect any ingredient to it.
On the page, ashwagandha is tied to stress and mood, ginseng and maca to energy, zinc and vitamin D to testosterone, and tribulus and maca to libido. Sleep is not linked to a named ingredient. Ashwagandha has been looked at in some small sleep studies, but the page does not make that connection.
So the claim stands without its explanation.
Treat sleep support as an unspecified benefit. If sleep is your reason to buy, ask the seller which ingredient they link to it and what the evidence is. Sleep depends mostly on habits, so fix those first: regular times, a caffeine cutoff and a dark, cool room. See a doctor if problems last.
