Consumer advice
This is a legitimate product with real, transparently dosed ingredients. If you want a convenient all-in-one sleep/stress supplement and don't mind the premium price, it's a reasonable choice. If you're budget-conscious, buy KSM-66 ashwagandha (600mg), L-theanine (200-300mg), and magnesium glycinate (200-400mg) separately for roughly 60-70% less. Don't expect the GABA to do much — oral GABA has a well-documented blood-brain barrier problem. Start with the subscription for the 15-25% discount, and give it at least 4 weeks before judging effectiveness (ashwagandha takes time). If you're on thyroid medication, sedatives, or immunosuppressants, check with your doctor before starting ashwagandha.
