The Claim
Withania somnifera supplementation at a dose of 300mg twice daily for 8 weeks significantly increases serum testosterone levels by 96.2 ng/dL (95% CI: 54.7, 137.5) compared to 18.0 ng/dL (95% CI: -15.8, 51.8) in placebo (p=0.004) in healthy young untrained males undergoing resistance training.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking ashwagandha supplements (300mg twice a day for 2 months) may boost testosterone levels in young men who lift weights, according to one study that found a much bigger increase compared to a placebo pill.

What the research says
1 studyThis study gave men either ashwagandha pills or fake pills while they weight-trained for 8 weeks, and found those taking ashwagandha had a much bigger testosterone increase (96.2 ng/dL) compared to the placebo group (18.0 ng/dL), exactly matching what the claim stated.
