Consumer advice
- • If you're looking for a melatonin-free sleep supplement, this is a reasonably honest product — but consider these points before buying:.
- • The ashwagandha (600mg KSM-66) and L-theanine (300mg) are the real workhorses here; don't expect results in 1–2 nights — give it 4–6 weeks.
- • The GABA inclusion is scientifically weak; don't buy this product primarily for the GABA.
- • The magnesium dose (150mg) is below what studies show is effective — if magnesium deficiency is a concern, consider a separate magnesium glycinate supplement at 300–400mg.
