Myth - The Molecular Weight of Collagen Affects Its Absorption in the Body

 Range of Edible Health collagen powders

We continue our series of collagen mythbusters  with this latest misnomer.

Originally, the market believed that the size of collagen molecules (known as the molecular weight) affected absorption. In other words, the smaller the collagen molecule size, the faster the absorption.

Molecular weight and collagen absorption into the body

As molecular weight is measured in Daltons, it was always believed that a 2,000 Dalton collagen would work better than a 5,000 Dalton product. Science has since disproved this. It has discovered that, regardless of  molecular weight, collagen molecules are broken down by enzymes in the body. This happens in the small intestine. These then enter the bloodstream in the same way, at the same size and time, and with no impact on efficacy, in spite of their molecular weight at the beginning of digestion.

Cultural beliefs and collagen absorption into the body 

Interestingly, science has failed to change beliefs around the world.  In Asia, it is still believed that the smaller the molecule, the better. Whereas in the USA, it is believed that the bigger the molecule, the better. In fact, neither is correct. As a result, the industry continues to supply various sizes of collagen to meet market demands, regardless of science.

Dalton weight - 2,000 or 5,000? 

Edible Health collagen in the UK is 2,000 Dalton, although we are currently considering a 5,000 Dalton option. This is because recent advances in manufacturing are showing us that the solubility, taste and smell may be slightly better. We are still testing this.  We will never stop looking for ways to advance our collagen, so that we can ensure we are always offering the best collagen to our customers.

Collagen quality matters most 

At Edible Health, we prefer to empower our customers with their health decisions.

So, rather than stating one size is better than the other, we stand by the science that molecular weight does not matter. What matters to us more is that the collagen we use is from the world’s leading manufacturer. It must reach our stringent requirements for the highest quality, purest collagen is paramount. As such, Edible Health collagen is manufactured in state-of-the-art factories with the strictest safety measures, most comprehensive testing, analysis and certification, and from a company with honest and transparent ethics.

Not only are quality and efficacy critical to our choice of collagen, we also source from Europe to minimise air miles and to maximise compliance with EU regulation, which is some of the strictest in the world. Rest assured, regardless of molecular weight, you can be certain that our collagen will always be the highest quality that is currently available. We may not be the cheapest, but we will always be the best!

We trust this article is useful and helps you in your understanding and research of the best collagen for you.
