"600mg KSM-66 ashwagandha dose"
This matches the top of the 300-600mg range used in published ashwagandha stress trials, unlike many underdosed competitors.
-
"Melatonin-free, non-habit forming formula"
None of the four listed ingredients have documented dependence risk, unlike melatonin or benzodiazepine sleep aids.
-
"Cortisol dropped 28% and 77% felt less anxious in 60 days"
No study is named or linked on the page, so this can't be checked against the actual ashwagandha trial it's citing.
-
"GABA quiets racing thoughts and improves sleep"
Oral GABA likely can't cross the blood-brain barrier in meaningful amounts, per the ongoing scientific debate on this exact question.

Consumer advice
If you want to try this stack, the doses of ashwagandha (600mg), L-theanine (300mg), and magnesium (150mg) are in reasonable ranges based on general research — this isn't an underdosed proprietary blend hiding amounts. But GABA's ability to reach the brain when swallowed is scientifically disputed, so don't expect much from that ingredient specifically. Check whether the "28%" and "77%" stats are footnoted to a specific published trial on this exact product or borrowed from generic ashwagandha research — if you can't find the citation, treat the numbers skeptically. If cost is a concern, buying KSM-66 ashwagandha and L-theanine as standalone supplements plus a magnesium glycinate product will likely run less than the $33-40/month price here. Skip if you're pregnant, breastfeeding, on thyroid medication, or taking sedatives, per the ashwagandha interaction warnings.
Claims vs Evidence
MODERATE1 of 6 claims supported by evidence. These grades score the marketing, not the product — a claim only counts as supported when the label discloses a dose that matches the studies behind it, so blends that hide doses cap at “partial” no matter how good the formula is.
