Glycine is the major inhibitory neurotransmitter in the brainstem and spinal cord, where it participates in a variety of motor and sensory functions. Glycine stimulates the production of serotonin, the "feel-good" hormone that helps elevate mood, improve sleep quality, and enhance cognition and memory. I was giving this to my daughter who has a neurological condition but didn't see any changes.

"HEALTH IS THE GREATEST GIFT..." Buddha

Glycine is a non-essential amino acid which is useful to us a supplement in several ways. As a building block of glutathione it can assist in your body's natural repair and detoxification. It is also super helpful at the end of the day. I make a warm glass of water in which I put 2 grams of glycine, one gram of taurine, and 200mg of magnesium. If using capsules instead of powder, try 2. I drink it down about an hour before bed and it always leaves me feeling pleasantly drowsy. I hope this helps!

Not as good as Swanson

The quality and ingredients are okay, but I didn’t notice much effect compared to other brands. The capsule size is fine, but the overall result was disappointing. Swanson’s glycine works better for me, so I wouldn’t repurchase this one.
