Absorption is a crucial aspect to consider when evaluating collagen supplements.  A 2002 study in the International Journal of Clinical Pharmacological Research found your gut’s digestive enzymes and acids—break down hydrolyzed collagen, which is the type found in most collagen peptide powders.

Absorption, also known as bioavailability, can and does vary significantly from supplement to supplement  During the digestion of proteins, hydrochloric acid and proteolytic enzymes break down the intact protein molecule into amino acids which are then absorbed through the intestinal wall. If these proteins are not properly broken down before they are absorbed, your bioavailability suffers tremendously and thus you are losing the many of the true benefits of collagen. You may be buying a 15g collagen serving, but how much of that is being absorbed?  DigeSEB is made up of three targeted digestive enzymes that aid in the breakdown of proteins, carbohydrates, fats and dairy.
