Glycine Capsules give you pure glycine, the smallest amino acid and the most abundant one in collagen, in a small amount that is easy to adjust. Each capsule provides 470mg and you take one a day with food. One pot holds 100 capsules, which is a 100 day supply.
Glycine is a building block for proteins and a signalling molecule in your nervous system, as well as about a third of collagen. Your body makes it and gets it from meat and bone broth, so people on a plant based diet take in less.
Glycine Capsules are most useful for:
If you eat collagen or gelatin, Classic Collagen Peptides Powder gives you glycine together with proline in the ratio the body uses.
Each capsule provides 470mg of glycine. There are no fillers or binders, only glycine and the vegetable capsule shell. L-glycine is another name for it.
Take one capsule a day with food. The amount can be built up one capsule at a time. At a higher evening amount of around six capsules, a pot lasts about two and a half weeks.
The capsules are suitable for vegans and vegetarians. They are free from gluten, dairy and nuts.
The capsules are made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, they are practitioner grade and guaranteed additive free.
Is glycine the same as magnesium glycinate or collagen?
No. This is glycine on its own, the free amino acid. Magnesium glycinate is magnesium bound to glycine and is taken for the magnesium, while collagen contains glycine as about a third of its protein alongside other amino acids.
How much glycine should I take a day?
Take one capsule a day, which gives you 470mg. People who take more in the evening often use around six capsules, which is close to 3g.
When is the best time to take glycine?
With food, at any time of day. Those who take a higher amount usually take it before bed.
Can I take it with other supplements?
Yes. For collagen it pairs with L-Proline Capsules, the other main collagen amino acid, plus Vitamin C Ascorbic Acid Powder, which your body uses to make collagen.
Does glycine have side effects?
Glycine is an amino acid found in everyday food and is well tolerated at these amounts.
Why capsules rather than tablets?
A capsule is a cellulose shell around the powder, so it needs none of the binders or coating that hold a tablet together.

Glycine provides amino acids that serve as building blocks for proteins.
Often best on an empty stomach for optimal absorption.
Yes, though taking separately may improve absorption.
Each capsule is 470mg of pure glycine in a vegetarian capsule. At one capsule a day a pot of 100 lasts just over three months. If you take a higher dose in the evening, around 6 capsules, a pot lasts about two and a half weeks.
People who want to run the dose the sleep research used (around 3 g before bed) and judge it for themselves, people taking a collagen product who want extra glycine alongside it, and vegans and vegetarians who get less glycine without meat and bone broth. There is no authorised health claim for glycine, so Nutri Tailor does not promise an outcome from it.
No. This is glycine on its own, the free amino acid. Magnesium glycinate is magnesium bound to glycine and is taken for the magnesium; the glycine in it is a carrier at a much smaller amount. Collagen supplements contain glycine as about a third of their protein, alongside other amino acids. Glycine capsules suit people who want the amino acid itself at a measured dose.
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
