Life Extension Glycine is a straightforward, vegetarian capsule built around the star ingredient glycine, an amino acid associated with relaxation and sleep support. Studies indicate that taking glycine before bed can improve perceived sleep quality and support detoxification and connective tissue health. The capsule format keeps things simple, and the brand's longstanding commitment to quality makes this a reliable daily choice. If you already use magnesium glycinate or a vitamin d supplement, glycine can slot into that routine, and some people pair it with msm for joint comfort.

Glycine is a basic amino acid that slots into everyday body functions and comes in a vegetarian capsule for easy use.

This blend supplies glycine as a pure amino acid, with the capsule holding a plant-based carrier and stabiliser to keep product integrity.

Glycine helps relaxation and might support good sleep quality, and also contributes to detoxification steps and connective tissue health.

It acts as a neurotransmitter involved in soothing neural activity and participates in collagen synthesis, which supports connective tissue and overall metabolic health.
