With a dosage of 600mg per capsule, it provides a substantial amount of the active herb to help the body adapt to stress and promote a sense of calm.
The standout quality of this supplement is its standardization to 5% withanolides, ensuring that each capsule delivers a consistent and potent dose of the active compounds.
