100mg per serving
A well-studied adaptogen tied to stress response and testosterone research.
Ashwagandha (Withania somnifera) is one of the most extensively studied adaptogens, with research covering stress response, sleep, and in some studies, testosterone and vitality measures in men specifically.
At 100mg, this is on the lower end of doses used in ashwagandha research, where studies commonly use 300mg to 600mg of standardized extract daily.
The specific extract type (root, leaf, or standardized to a particular withanolide percentage) isn't specified on the label, which matters for comparing against clinical research.
