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.

No Longer Need Sleeping Pills

Posted by Baroness Marcella on March 20 2018 | Verified Purchase

I’ve been taking this for over 5 months and I couldn’t be more pleased. I take the recommended dosage of 3000mg about 730pm every night and I now no longer need to take benzodiazepine based sleeping pills. This works wonders! It took a few weeks to build up in my system but it’s definitely worth it. I have malabsorption issues but find this formulation easy to digest and it seems to metabolise very well. It’s so much better than to take addictive sleeping pills.

Thanks for your feedback!

I use this product to help with sleep. It works very well and is not habit forming. There is no brain fog the next day.
