Thorne Deep Sleep Complex review

Thorne Deep Sleep Complex is here for buyers who do not want melatonin. Each two-capsule serving combines 500mg of Maizinol, a young green corn leaf extract standardized to 0.2% 6-MBOA, with 200mg of L-theanine and 100mg of chamomile extract. Thorne describes Maizinol as a patented, non-hormonal botanical and pitches the product at people who struggle to fall asleep because of stress or a racing mind, or who wake during the night. The FAQ says each ingredient is tested for identity, purity and potency, including heavy metals, pesticides and microbes, and the product carries the NSF Contents Certified mark. Thorne also says it is designed to avoid morning grogginess. The cost is steep: $52 for 60 capsules is 30 servings, about $1.73 a night, the highest on this list. Thorne recommends checking with a health-care provider before combining it with melatonin or prescription drugs.
