Great product

I have adrenal fatigue with high nighttime cortisol. This product helps increase my seretonin levels so I don't wake up hot and sweaty in the middle of the night. I started with the tablets, but they didn't work as well. These work great.

I take multiple amino acid to get my HGH back to normal after the pregnancy and yet it is hard to say on the effect of each of it. yet I got back my sleep, and my mood improved (when I have a chance to sleep with 5mo in the house)I trust this brand and will continue taking it.

I liked this product much better than the powder L-tryptophan.

Odd reaction

Adding this to my regimen caused me to grind my teeth in my sleep, to the point of significant pain. Perhaps the L-tryptophan interacted with something else I'm taking, either prescription or OTC, but that's just a guess on my part. Unfortunately, it was a side-effect that caused me to stop taking it after just a week.

Frist time I have tried this product. I have trouble getting to sleep, and this seems to help...sometimes, not always.
