Glycine at a Glance, What Makes It Essential?

Glycine is a non-essential amino acid that serves as a fundamental building block for proteins throughout your body. Most notably, it comprises one-third of all collagen molecules, making it important for skin elasticity, joint comfort, and connective tissue resilience.

Beyond structural support, glycine functions as a neurotransmitter in your central nervous system, helping regulate nerve signals that influence mood, cognition, and sleep quality. It also plays a vital role in producing glutathione, one of the body's key antioxidants, providing cellular protection against daily environmental stressors.

While your body produces glycine naturally, active lifestyles, aging, and ongoing stress can create higher demands. This "conditional essentiality" explains why many health-conscious adults find targeted glycine supplementation supports their energy, recovery, and overall vitality goals.

Supports Antioxidant Protection

As a precursor to glutathione, glycine helps your body support its natural ability to manage free radicals particularly valuable for those juggling demanding careers, intense training, or environmental challenges. Research shows adequate glycine intake supports cellular resilience and healthy aging processes.
