Glycine 1000 mg by Life Extension – 100 Vegetarian Capsules

What Is Glycine 1000 mg?

Life Extension's Glycine 1000 mg delivers a therapeutic dose of glycine — the simplest and most abundant amino acid in the human body — in convenient vegetarian capsules. While glycine is technically non-essential (the body can produce it), research consistently shows that most people do not synthesize enough to meet optimal physiological demands. Supplementation has emerged as a powerful strategy for improving sleep quality, supporting collagen production, and promoting healthy metabolic function.

Key Benefits

• Healthy sleep support – Clinical studies show glycine improves sleep quality, reduces time to fall asleep, and enhances next-day alertness without grogginess
• Collagen & joint health – Glycine is the primary amino acid in collagen — essential for skin elasticity, joint cartilage, tendons, and connective tissue
• Cognitive function & mood – Glycine acts as an inhibitory neurotransmitter, promoting calm, mental clarity, and healthy stress response
• Metabolic health – Supports healthy blood sugar metabolism and insulin sensitivity
• Detoxification – Glycine is a key substrate in the synthesis of glutathione and bile acids, both essential for detoxification
• Healthy aging – Glycine levels decline with age; supplementation supports longevity pathways including mTOR modulation

What Makes It Different?

Glycine is one of the most underrated amino acids in longevity science. Recent research — including studies linking low glycine to accelerated aging — has renewed interest in this simple but powerful nutrient. At 1,000 mg per capsule, Life Extension’s formula delivers a clinically relevant dose in a clean, Non-GMO, gluten-free vegetarian capsule with no unnecessary fillers.

Who Should Take This?
