This is by far the most common type, and is found in your skin, bones, teeth, and connective tissue. Along with type II, it's the most important for healthy joints. Type II collagenThe most effective formulations use ingredients like plant oestrogens and vitamin C to help boost skin's collagen production, rather than containing collagen itself, whose particles are too large to reach the deeper levels of skin. Collagen is the most abundant protein found in the body and plays many vital roles, providing structure and strength to our skin, bones, tendons and tissues. What’s more, the body’s ability to synthesis collagen can decline as we age. Marine collagen does have some other known advantages, however. Notably, it is a far more sustainable source of protein than other kinds.

No. Two scoops — 12 g or a half ounce — are 45 calories. While excess intake of anything can make you gain weight, it’s unlikely that adding marine collagen in normally consumed amounts will cause weight gain, says Jampolis. The Bottom Line on Marine Collagen If you want to try marine collagen, follow the instructions on the label for the dosage. Also, it’s always best to talk to your doctor first before taking any supplement to make sure that it’s safe for your individual health concerns.

Plant oestrogens and vitamin C boost the skin's collagen, providing a noticeable improvement in hydration, plumpness, and texture.

While collagen treatments got their start in skin care, the protein is not well suited for topical applications because it is too large to penetrate the skin, says Joshua Zeichner, MD, director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. This is why some formulations use collagen peptides, or hydrolyzed collagen, which has been partially broken down. Meanwhile, Logan recommends opting for type 1. “Type 1 collagen makes up 90 per cent of the collagen in the body, so it is certainly the one we should try and focus on the most – especially when looking to support the skin. Type 1 collagen is concentrated around the skin, bones, tendons and ligaments, helping to provide structure and strength.” Which collagen is best for anti-ageing?Additionally, the Marine Drugs paper points out that some people avoid animal-derived collagen out of fear that it may potentially transmit diseases, such as bovine spongiform encephalopathy, also known as mad cow disease. If you are allergic to fish, you should absolutely not take marine collagen. Also, since collagen is a protein, you should consider this a protein supplement. Depending on the brand, two scoops might contain 11 g of protein. If you have severe kidney disease and your doctor has recommended limiting protein, then you’ll need to count the grams of protein consumed from marine collagen powders or capsules, says Jampolis.
