Overview

Ashwagandha is one of the most researched supplements for stress. For South Africans dealing with stress, it offers a natural approach backed by scientific evidence. This guide covers everything you need to know: how it works, optimal dosage, best products available at Onelife, and what to expect.

How Ashwagandha Works for Stress

Ashwagandha is an adaptogen that helps your body resist stress. It lowers cortisol levels and supports adrenal function.

“Across seven well-designed randomised controlled trials, ashwagandha supplementation was associated with statistically significant reductions in both subjective stress measures and serum cortisol. The consistency of findings across different populations is compelling.”

Scientific Evidence & Research

A 2019 randomised, double-blind trial in Cureus (Salve et al., PMID: 32021735) demonstrated that 240 mg/day of ashwagandha extract significantly reduced stress, anxiety, and serum cortisol in healthy adults over 60 days, with cortisol declining approximately 23%. The benchmark 2012 study in the Indian Journal of Psychological Medicine (Chandrasekhar et al., PMID: 23439798) found 300 mg twice daily reduced perceived stress by 44% vs placebo. A 2021 systematic review of seven RCTs in Current Neuropharmacology (Speers et al., PMID: 33820868) confirmed consistent, statistically significant stress and cortisol reductions across all reviewed trials.
