Nature's Sunshine Nervous System
Click for full label (NIH)How to read this
Clinically dosed — the label discloses at least as much ashwagandha per serving as clinical trials used. The black tick on the bar marks the trial dose.
Under clinical dose — the label is honest about the amount, but it's less than the studies used, so the studied effect may not apply.
Dose not disclosed — the label doesn't let you verify the amount at all (usually a "proprietary blend" that only prints the mixture's total weight).
Data verified 2026-07-08 · Scored against: clinical trials of KSM-66, 300-600mg/day at 5% withanolides; doses normalized to a 5%-withanolide basis before comparison since potency scales with disclosed concentration (10%-standardized extracts like Sensoril need proportionally less raw material).

FAQ
Does Nature's Sunshine Nervous System have enough ashwagandha?
You can't tell from the label. Nature's Sunshine Nervous System does not disclose a verifiable ashwagandha amount per serving, so there's no way to confirm it reaches the 300 mg/day clinical dose.
Does Nature's Sunshine Nervous System use a proprietary blend?
Yes. The ashwagandha is inside a proprietary blend, so the label shows only the blend's total weight — not how much ashwagandha you actually get.
What's a better-dosed ashwagandha than Nature's Sunshine Nervous System?
Clinically dosed, no-blend options include: Herbadiet Men Health (95 mg); Solaray SharpMind Stress (120 mg); NatureCity TrueZs (120 mg). All disclose at least 300 mg per serving on the label.
