The reduction from 600 mg to 500 mg per capsule is part of a formulation and standardisation update by the manufacturer. The new strength still provides a clinically effective dose of KSM-66 Ashwagandha, as most scientific studies show proven benefits for stress reduction, energy, and vitality within the 300–600 mg daily range. Therefore, the 500 mg dosage remains safe, effective, and medically appropriate for regular use.
