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.

Life Extension products at times contain excipients I do not like, but this one [Glycine] passed my test. A very good feature of Life Extension products is that their website always have excellent research papers supporting the manufacture and marketing of their supplement products.

Good sleeping aid

Posted by 5437867462779151881 on Jan 24, 2017 | Verified Purchase

Learnt about glycine , funny enough, from my dentist, He is taking it as lozenges under the tongue for a very quick effect. I just open a capsule and do the same. Asleep in no time at all, provided I am a recovering insomniac. Tried hundreds of different remedies, only GABA with l-theanine and glycine seem to work, plus they are aminos, no harm at all. Recommend to experiment.
