Glycine

Glycine is a simple amino acid that plays an important role in detoxification and overall metabolic health. It’s one of the three amino acids your body uses to make glutathione, the master antioxidant that protects cells and helps your liver neutralize toxins. Glycine also supports restful sleep, joint health, and blood sugar balance.

Does it really work?

Yes, but in a quiet, behind-the-scenes way. Unlike herbs that actively “stimulate” detox, glycine works as a building block. Clinical studies show glycine supplementation can boost glutathione levels, improve liver function in people under oxidative stress, and support healthy detox processes.

Can I get enough in real food?

Yes. Glycine is naturally present in collagen-rich foods (like skin, cartilage, and connective tissue), bone broth, gelatin, and also in smaller amounts in meat, fish, and legumes. Many people don’t eat enough collagen-rich foods to fully meet higher needs, which is why supplementation can help.

Do I need a supplement for everyday health?

Glycine isn’t technically essential, but most people benefit from having more than the bare minimum. Since many diets are low in collagen-rich foods, taking glycine daily can be a safe, gentle way to support detox, sleep, and metabolic balance.
