What people say about Glycine and anxiety
“I've been taking about 4.5 grams of glycine about an hour before bedtime to benefit sleep (the evidence on this seems relatively strong).”
“I take a lot of glycine...I take a couple of teaspoons of the powder every night and it helps me sleep without any sort of payback.”
“I tried using glycine as a sleep aid for a while and it did the opposite. Turns out it's stimulating for some people and sedating for others.”
“Glycine works REALLY good for me for sleep, but the way i get it is in the form of collagen peptides, or just gelatin. That way you get all the other amino acids as well, it knocks me out and my sleep is very deep.”
