Buy Glycine Powder (360g): sleep, collagen and liver support
Crystalline Glycine Powder by Nutrimuscle, in a 360 g pot, is 100% pure amino acid with no additives, no flavourings and no sweeteners — prized for its naturally mild taste and excellent value for a roughly two-month course. Available at our Paris shop, with Click & Collect and delivery across France and Europe.
Why supplement with glycine?
Although classed as non-essential, recent research suggests the body’s own glycine production is often insufficient to cover demand for collagen, glutathione, creatine, bile acids and haem synthesis — leading some to call it “conditionally essential.” The richest dietary sources are animal connective tissues (bone broth, skin, cartilage, gelatin), so people eating mostly lean meat or following a vegetarian diet may fall short.
Glycine and sleep quality
One of the best-documented areas for glycine is sleep. Several studies link glycine taken before bed to a subjective improvement in sleep quality, largely through its ability to slightly lower core body temperature — a physiological cue that eases falling asleep. Study dosages are typically around 3 g, taken 30–60 minutes before bed; at that dose a 360 g pot lasts around 120 days, roughly four months.
Glycine, collagen and liver support
Glycine accounts for one in three amino acids in collagen, the body’s most abundant structural protein — supporting skin elasticity, joint comfort and tendon strength, which naturally decline with age as collagen synthesis slows. Glycine is also one of three amino acids that make up glutathione, the body’s main intracellular antioxidant, supporting the liver’s detoxification processes, and contributes to bile acid production for fat digestion and to intestinal lining renewal.
How to use & precautions
The recommended dose is 6 g a day (about five scoops), dissolved in water, juice or a smoothie. For sleep, take in the evening 30–60 minutes before bed; for other uses (recovery, collagen, detox) intake can be spread through the day. A 360 g pot lasts about 60 days at 6 g/day.
For adults. Not a substitute for a varied, balanced diet. Do not exceed the recommended daily dose. If pregnant, breastfeeding, or taking medication, consult a healthcare professional before use.
Frequently asked questions
Is glycine suitable for a vegetarian diet?
Yes — Nutrimuscle’s crystalline glycine is synthesised, with no animal-derived component, making it suitable for vegetarians and vegans, who often consume less collagen from animal sources.
Can glycine be combined with other supplements?
Yes — it pairs well with magnesium for relaxation and sleep, and with vitamin C for collagen synthesis. Our team at Herba Barona can help build a protocol suited to your goals.
