Collagen is the most abundant high molecular weight protein in invertebrate and vertebrate animals, including mammals. Its function is structural and there are different types according to their specific organization in the different tissues of the organism.
The growth of collagen consumption in its various forms, native or hydrolyzed, as a food supplement is nothing new, but it has experienced a strong increase in recent years. Therefore, the nutraceutical sector constantly seeks new natural sources of collagen, as well as updating the methodologies used in its production.
For some time in the food supplement market has appeared information that is leading to misunderstandings and confusion between those responsible for the marketing of supplements, as well as the final consumer. We refer to the so-called algae collagen.
This claim is totally incorrect because the algae do not contain collagen.
The most common sources of collagen are of bovine, porcine, avian and marine origin, being in this last case the fish the animals from which the collagen is obtained.
It is possible that the use of the term marine and the tendency not to consume ingredients derived from animals has led to think that marine algae can be used as a source of collagen. The truth is that marine collagen can only be obtained from fish, sponges and jellyfish, all of them animal sources.
The only way to combat incorrect and biased information that can be received by the consumer is to obtain this information from reliable sources such as companies in the nutraceutical sector specialized in collagen in its different forms and origins.
