What are marine collagen supplements? And what they are made of?
Marine collagen supplements are dietary products derived from the collagen found in marine sources, primarily fish. Marine collagen supplements specifically refers to collagen extracted from the skin, bones, and scales of fish, or sometimes from marine invertebrates like seaweed.
Marine collagen is typically made through a process that involves:
Source material: high-quality marine collagen comes from fish skin, bones, and scales, though some supplements use seaweed or other marine sources.
Extraction and hydrolyzation: collagen is extracted and broken down into smaller peptides through hydrolyzation, making it easier for the body to absorb.
Formulation: these peptides are then made into various supplement forms—powders, capsules, or liquids—for convenient daily use.
What are the benefits of marine collagen supplements?

Marine collagen has been the subject of various studies, and the results are promising. Research suggests that marine collagen may offer several benefits, including:
-
Skin health: Marine collagen helps maintain skin structure, increasing firmness and elasticity. It acts preventively against wrinkles by hydrating the skin. It also helps combat acne and manage skin pigmentation.
-
Hair and nails: marine collagen strengthens hair, making it shinier and less prone to breakage. Nails become stronger, less likely to split, and stop peeling.
-
Bone and joint health: collagen consumption supports joint health, reducing pain and inflammation, and strengthens bones, improving their density.
-
Muscles and tendons: collagen helps with faster muscle recovery, improves muscle strength and endurance, and supports tendon elasticity and strength.
-
Antioxidant properties: Marine collagen acts as an antioxidant, helping to combat free radicals and protect cells from damage.
Which marine collagen is best?
When choosing a marine collagen supplement, consider the following factors to find the best option:
-
Type: look for supplements that specify the type of collagen used. Marine collagen primarily contains Type I collagen, which is beneficial for skin and bone health.
-
Hydrolyzation: hydrolyzed collagen, or collagen peptides, is easier for your body to absorb. Most high-quality marine collagen supplements use this form.
-
Purity and quality: choose products from reputable brands that undergo third-party testing for purity and quality.
