The amino acid glycine plays a key role in maintaining a healthy central nervous system (CNS).* It is considered one of the most important inhibitory neurotransmitters in the CNS, particularly in the brainstem and spinal cord.* Studies show glycine can help improve memory retrieval in individuals with a wide variety of sleep-depriving conditions, such as jet lag and overwork.* The benefits of glycine are not just limited to the CNS. Glycine also plays a key role in phase II liver detoxification by having a direct effect on toxin elimination or by increasing the level of glutathione.* Glycine also helps modulate cytokines associated with obesity.*

Glycine is one of three amino acids needed to produce creatine, which in turn supplies energy to muscle and nerve cells.* The other two amino acids are arginine and methionine. High concentrations of glycine are found in the muscles, the skin, and other connective tissues. Approximately 30 percent of collagen is composed of glycine.

Glycine plays an important role in supporting a healthy digestive system by helping to regulate the synthesis of bile acid, which the body uses to digest fats.* Glycine also plays a role in regulating the utilization of glucose during energy production.*

Quality and Trust from this Brand

I was looking for a specific product, and as well I wanted to be reassured that I was buying from a trusted website/company/brand. As I did my homework I found that the product I was looking for is available at Thorne. It also appears that the reviews for Thorne were positive enough to reassure me that I would be happy with my purchase. My product arrived in a very timely manner and I am looking forward to seeing the changes that this product can deliver to make my life better.

Wine lover

I started taking this along with potassium because I have become more sensitive to alcohol over the last few years. I noticed a difference within a week. It’s nice to be able to enjoy a few glasses of wine with friends without feeling crummy the next day.

Helps sleep

Love this product! Helps with sleep. I feel more rested when I wake up in the morning. And a nice benefit is it eases some of my mind chatter.

My go-to for a wind down

Glycine is my standby for moments of stress. It helps calm my mind and I don't feel sleepy afterwards. If I want it to work extra fast, then I take it out of the capsule because it tastes sweet.
