Beef vs Marine Collagen
By Dr. Steve Bennett

TLDR: Marine collagen gives you more bang for your buck!
Marine Collagen is Better Absorbed in your Body
Marine collagen gives you more bang for your buck. Fish collagen consists of smaller peptides (peptides=pieces of protein) than bovine sources and as a consequence is 1.5 times more easily digested, absorbed and distributed throughout the body. This enhanced bioavailability means your body may benefit more from its anti-aging and tissue-building effects.
Marine Collagen has better Water Solubility
Fish collagen dissolves readily in water, which makes it easy to dissolve in your favorite beverage, while bovine collagen is less soluble.
Marine Collagen Provides Better Suitability
Type I collagen is the most abundant type of collagen in the human body and accounts for 80% of the collagen in skin. As we age, the ratio of type I to type III collagen in our skin decreases, which weakens the skin and contributes to wrinkles. While bovine collagen contains both Type I and Type III collagen, marine collagen is primarily Type I collagen. This means it is most similar in structure to human collagen, and therefore is ideally suited to top up your body’s collagen needs.
Marine Collagen Improves Skin Moisture
Marine collagen supplementation protects against skin photoaging by repairing skin collagen and elastin protein fibers, improving moisture retention and improving hyaluronic acid content. Although bovine collagen has been shown to improve skin collagen content, it had no significant effect on skin moisture or hyaluronic acid content.
Marine Collagen Is Better for the Environment
Roughly 11.7 million tons of unused fish parts are discarded annually during processing, so using them to make collagen is environmentally friendly. On top of that, fish protein in general releases far less greenhouse gas emissions than most meat products.
Although cowhides are abundant byproducts and cheap to produce, their sourcing plays a negative role in climate change. Livestock production accounts for 14.5% of all human-induced greenhouse gas emissions with beef and bovine milk production contributing 41 and 19% of those emissions; that includes grass-fed as well as grain-fed animals.
