Collagen is increasingly regarded as essential in beauty and wellness routines. From powders and pills to skin care products, collagen is everywhere, but with so many options available, it can be confusing to know which one is best for you.
One of the most common questions people ask is whether marine collagen is better or bovine collagen is better for your skin.
Both are popular supplements, and both have unique benefits and can support skin health. They also come from different sources and might work differently in your body. If you're trying to choose between the two, this guide is just for you.
What is collagen and its significance
Collagen is the most abundant protein in your body. It works like the glue that holds everything together, and your skin, bones, joints, even your hair and nails.
As the body starts ageing, it naturally processes less collagen. By your mid-20s, production starts slowing down, and by the time you reach your 40s or 50s, collagen levels have dropped significantly. That leads to:
-
Wrinkles and fine lines
-
Sagging skin
-
Loss of elasticity
-
Joint stiffness
That's exactly where collagen supplements like marine collagen and bovine collagen come into the picture. They aim to restore collagen levels, keeping your skin youthful and also your body strong.
What is marine collagen?
Marine collagen, as the name suggests, is basically sourced from fish skin and scales. It is made of type 1 collagen, the most abundant in your skin, hair and nails. Since it's rich in type 1 collagen, it directly supports smooth, firm skin.
Experts suggest that marine collagen can reduce fine lines and slow visible ageing. It helps you retain your moisture and also gives you a plump, youthful look.
Other than that, it's very easy for your body to absorb and also promotes its own healing. It can support gut health.
A meta-analysis of 26 randomised controlled trials (2023) found that hydrolysed collagen (from various sources, including bovine) significantly improves skin hydration and elasticity compared to placebo.
What is bovine collagen?
It is derived from cow hides and bones. It contains both type 1 and type 2 collagen. Type 1 collagen is found in skin and bones, while type 3 collagen is found in skin and muscles.
It supports both the structure and texture of your skin and also helps the skin heal and renew itself quickly. This type of collagen keeps your skin supple and less prone to sagging. Besides that, it supports joint and bone health and also promotes muscle recovery.

Which is better for your skin health?
If your main objective is better skin health, glowing, youthful and wrinkle-free skin, marine collagen might be slightly better. It is because it's mostly type 1 collagen, which makes up 80% of your skin, plus it's also a smaller peptide size means it's absorbed quickly by your body.
But bovine collagen is not far behind. As it contains both type 1 and type 3 collagen, it supports the skin structure and elasticity while benefiting your muscles and joints at the same time.
Absorption and bioavailability
One of the main reasons marine collagen is often marked as better is because its smaller peptide sites will stop smaller peptides which means faster absorption in the gut.

Both deliver effective support depending on your preference.
