**DHEA** at 25mg per tablet sits at the bottom of the clinically studied range (25–100mg/day). Most RCTs — including a meta-analysis of 42 publications — used 50mg/day, where significant increases in testosterone and reductions in fat mass were observed in older adults. At one tablet daily, you're getting half the most commonly studied dose, so the hormonal support may be modest.
The 300-count bottle gives you nearly a year's supply at the label dose. If your goal is meaningful hormone support, you could take two tablets to reach 50mg — right at the dose most clinical trials used. That flexibility is a practical upside of the low per-tablet dose.
This is a hormone precursor, not a vitamin — the label warnings about potential side effects (acne, hair changes, mood shifts) are worth reading carefully. DHEA is best used with bloodwork to confirm you actually have low levels, since supplementing with adequate levels offers no established benefit and may carry unnecessary risk.
