If you're dealing with daily stress, this formula combines four adaptogens in a single capsule. The lead ingredient is **Sensoril Ashwagandha** at 250mg (standardized to 8% withanolides) — a patented extract with clinical trials showing cortisol reduction and stress relief at this exact dose. That's a meaningful amount backed by real research.
The supporting cast includes **Lavender** extract (150mg), **Eleuthero** (150mg), and **Rhodiola** (75mg). Lavender at 150mg is close to the 80–160mg Silexan dose studied for anxiety. Rhodiola at 75mg falls short of the 200–400mg range used in most clinical trials for stress and fatigue, so you're getting a partial dose there.
The suggested use is 1–2 capsules twice daily (up to 4 capsules), which would double or quadruple these doses. At one capsule per serving, the rhodiola and eleuthero are underdosed — you'd need to follow the higher end of the suggested use to get all four ingredients into their studied ranges.
