  • Very relaxing

    I don't know how this product really works without mixing powdered inositol (B 8) with it (2 1/2 t). Tryptophan can not pass the blood brain barrier without a carrier. Inositol is that carrier. All the ingredients that this product has, are exactly what is needed to help one sleep. The taste is great too and the inositol adds a nice sweet taste. This company should include the inositol and they would have a definite winner. Again, I don't know how it would work without the B-8 but with it, it works great!!!
