Fish Collagen produces Positive Changes in Skin Health

As we age, the type I collagen in our skin (the same kind that’s in marine collagen) weakens, leading to visible signs of aging including saggy and wrinkly skin (1). Preclinical studies show that ingesting marine collagen repairs skin collagen and elastin protein fibers and produces a significant thickening of the outer skin surface (epidermis). Human studies have reported decreased wrinkles and improved skin hydration and firmness following marine collagen supplementation (2,3).

Provides Antioxidant Protection

Marine collagen contains several amino acids: lysine, glycine, proline, and hydroxyproline (1). Proline and glycine play important antioxidant roles by protecting against free radicals that cause cell damage (4,5). Hydroxyproline is made into glycine and it may help regulate a cell’s oxidative state (6). Preclinical studies show that marine collagen protects against oxidative skin damage caused by ultraviolet (UV) light (sunlight) (7).

Promotes Bone Growth/Healing/Strength

In cell culture, ingesting marine collagen increases collagen synthesis and helps incorporate minerals into the bone matrix.  In addition, marine collagen supplementation significantly increases the size and mineral density of femur bones (8).

Bone strength depends not only on the quantity of bone tissue but also on the quality, which is altered by its geometry, shape, mineral content and composition, and its collagen microstructure. In cell culture, marine collagen improves collagen quality while supplementation in animals significantly increases bone mineral density and toughness (8,9).

Improves Protein Intake and Body Composition

Optimal dietary protein intake beneficially impacts weight management, lean body mass, muscle repair, and immune function, among other benefits (10). It is also essential to maximize athletic performance by helping to build muscle and improve workout performance and recovery. Marine collagen is a pure protein with no fat or carbohydrate to dilute its impact. In addition, the protein building block, proline, more than any other amino acid, is needed for whole body protein synthesis (6). Therefore, marine collagen’s proline content can help increase lean body mass.
