How Ashwagandha Capsule works

Ashwagandha is thought to act as an adaptogen, helping the body manage stress by balancing the hypothalamus-pituitary-adrenal (HPA) system and lowering cortisol levels. It also contains antioxidant and anti-inflammatory compounds called withanolides that may support brain and immune function.

Ashwagandha Capsule dosage

Most studies used root extract taken as capsules, though some products combine root and leaf extracts. Treatment durations in studies generally ranged from 1 to 3 months, with some benefits noticed within 2 weeks and increasing over 6 to 10 weeks. Long-term safety beyond 3 months of continuous use has not been thoroughly established, so periodic breaks or medical supervision are recommended.
