Product Overview


  • Amino Acid for Healthy Sleep
  • Dietary Supplement

Glycine is a conditionally essential amino acid that serves as both an inhibitory and excitatory neurotransmitter. It is the chemically simplest and most omnipresent of all the amino acids. It combines with many toxic substances, converting them to harmless forms which are then excreted.

This amino acid has a calming effect on the brain and is also involved in growth. Research suggests that glycine may help promote deeper sleep. Glycine also has a positive impact on attention and memory in adults. Glycine may also help boost the immune defense system and has oxidative stress regulating effects.

Most people need to take between one to three grams of glycine to be effective even though studies show high doses are safe. However, most glycine products are only available in 500 mg capsules. That makes taking higher doses cumbersome and costly. However, Life Extension’s glycine comes in easy-to-swallow 1000-mg capsules.

Suggested Use

Read the entire label and follow the directions carefully prior to use.

Take one (1) to three (3) capsules on an empty stomach at bedtime, or as recommended by a healthcare practitioner.

Other Ingredients

Vegetable cellulose (capsule), ascorbyl palmitate.

glycine is the most wonderful natural sleep aide

Posted by 5500131298500370096 on Oct 02, 2016

I have insomnia very bad and at 82 years old, I do. It ,lIke to take drugs. I read about the natural amino acid GLYCINE and researched a lot of,them and Life extension sounded the best to me and very reasonably prices. I am so thrilled with it. it actually helps me get a restful nights sleep after tossing and turning for years. I sent for a,bottle for my sister who is 85 and she has had tremendous results from it also. I would recommend it to anyone who has problems sleeping.
