Glycine with E-number 640 is a simple amino acid, which is both a natural part of the diet and which is formed naturally in the body. Glycine is also marketed as a dietary supplement.
As an excipient, glycine is a colourless, crystalline solid that is used as a flavour enhancer and as an acidity regulator. Glycine has a slightly sweet taste but must not be used as a sweetener.
Pharma Nord uses glycine produced in a simple synthetic process, which guarantees purity.
There is no limit to how much glycine may be used.
