What to look for in collagen powder and how to read the label

Collagen peptides have a unique amino acid profile to support tissue-building for your skin. If a company is proud of their amino acid profile, they&#;ll publish it just like we do here at Bare Biology (you can read Skinful&#;s full amino acid profile here). 

If you are looking for more details, kindly visit .

If you can&#;t find this information on the packaging or the manufacturer&#;s website, you won&#;t be able to make an informed decision as to whether the collagen it contains will actually work for you.

So which amino acids should you be looking out for? While the full profile will have benefits to the skin, proline, glycine and hydroxyproline are particularly important because your body needs all three for the raw materials to make its own collagen. Human collagen is made almost entirely of these proteins, in roughly the same ratio you find in marine collagen supplements like Skinful. You won&#;t find them in meaningful amounts in any other foods. 

The other important amino acid to be aware of is arginine, because this antioxidant also helps with the production of collagen.
