There is nothing wrong with taking collagen orally the smaller its molecular weight, the easier it is to absorb.
However, we often forget that absorption is not the same as utilization. When collagen molecules reach the gastrointestinal tract and are absorbed by the body, our gastrointestinal tract first converts them into short chains of amino acids before they can be transported to the parts of the body that need collagen for use.
If the molecular weight is too small, it is easily broken down by the body into amino acids rather than the amino acid chain required by collagen, and it cannot be synthesized into collagen by the body.
Studies have shown that the molecular size of collagen is generally between 2000 and 4000 Daltons, and the molecular weight of collagen in Vida Glow Marine collagen powder is as low as 2000 Daltons (source: https://www.mdpi.com/1420-3049/24/22/4031/htm;) .
To sum up, if the molecular weight of collagen is too small, it may be used by the human body for other purposes (such as enzymes and muscles), which is not highly utilized, and the molecular weight of collagen is too large and difficult to absorb. Vida Glow Marine collagen powder has the right molecular weight of collagen, which is a peptide grade fine powder of natural hydrolyzed collagen. It can be better absorbed and utilized by our bodies.
