Why this formula

Bioavailable forms. Precision dosing.

Ashwagandha (Withania somnifera) is the most-researched adaptogen in herbal medicine. The standardized extract used here delivers withanolides — the active compounds research has consistently associated with the herb's calming effect on the stress response.

Paired with L-theanine, an amino acid found in green tea, the formula targets both sides of stress: ashwagandha for the adrenal axis, L-theanine for alpha-wave brain activity. Each capsule delivers 600mg withanolide-standardized ashwagandha and 100mg L-theanine.

Health Canada has reviewed and licensed this formulation under NPN 80123260. Each lot is third-party tested at an independent Canadian lab. Take consistently for 4–8 weeks for the formula's full effect.
