Certain nutrients, including many vitamins and amino acids, are degraded by the temperatures, pressures and chemical treatments used during manufacture, and hence must be added after manufacture to avoid nutritional deficiency.

It is a major constituent of bile and can be found in the large intestine, and accounts for up to 0.1% of total human body weight.
