1000 mg 100 vegetarian capsules
Item Catalog Number: 01669

Glycine is a conditionally essential amino acid that serves as both an inhibitory and excitatory neurotransmitter.236-238 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.239,240

This amino acid has a calming effect on the brain and is also involved in growth.241-250 Research suggests that glycine may help promote deeper sleep.238,242,243 Glycine also has a positive impact on attention and memory in adults.241-254 Glycine may also help boost the immune defense system and has oxidative stress regulating effects.255-258

Most people need to take between one to three grams of glycine to be effective even though studies show high doses are safe.259,260 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.

    Comments about Life Extension Glycine, 1000 mg 100 vegetarian capsules:

    After years of going to sleep quickly and easily,
    but waking up a couple hours later and not being able to go back to sleep, Glycine (I use 1000 mg)
    right before bedtime, has allowed me to sleep 7-9 hours uninterrupted. Amazing and so simple and safe.
