What exactly is Marine collagen?
Marine collagen is sourced from fish – typically from the skin of wild-caught cod that are not at risk of being endangered. Marine collagen is a type 1 collagen that's derived from fish collagen peptides – this type of collagen actually has the highest, most bioavailable source of collagen available on the market.
Turns out, newer studies have recently emerged indicating that consuming anywhere between 1,000-1,500mg of collagen per day may still be enough to get you glowing.
A 2019 review of clinical studies found that taking 2.5–15 grams of hydrolyzed collagen peptides each day may be safe and effective ( 29 ). A smaller daily dose of 2.5 grams could benefit joint pain, skin health, and hydration ( 7 , 30 , 31 ).
There's no standardised dosage when it comes to hydrolysed collagen supplements but studies indicate amounts over 2500mg a day are beneficial for skin health.
Current research reveals that collagen use could result in a reduction of wrinkles, rejuvenation of skin, and reversal of skin aging [16], which may improve skin hydration and elasticity [17].
Studies on humans have also shown that marine collagen can reduce wrinkles, improve skin elasticity, and enhance the overall structure and appearance of skin.
The good news is that collagen is considered safe for most people, and there is no standardised upper limit. In most cases, more collagen often gives you better results. This is why we usually recommend taking up to 10,000mg of marine collagen on a daily basis.
Studies have shown that supplementing with collagen peptides — broken down collagen that's easier for your body to absorb — may be beneficial for older people and promote skin and bone health during aging.
When you take a collagen supplement, you are increasing the amount of certain amino acids in your body. If you take too much collagen, it can throw off the balance of amino acids in your body and lead to side effects such as headaches, digestive issues, and fatigue.
The skin responds the fastest to collagen supplementation, and to relatively low doses. To increase skin's elasticity, firmness, and texture, and help prevent fine lines and wrinkles, studies show that taking up to 2.5 grams is effective.
How long does it take to see the benefits of marine collagen?
How Long Does It Take for Marine Collagen to Work? It's natural to want to see the benefits of any supplement or diet change right away, but you'll have to wait some time. With regular consumption, Jampolis says that you may see skin benefits in 8 to 12 weeks, enough time for skin to repair and turn over.
Research has shown indicated that adults can safely consume between 2.5 to 15 grams of collagen a day. Read the label on your supplement to see how much it contains. Many people take 1-2 tablespoons of collagen powder per day.

Both bovine and marine collagen provide the same benefits. Both are great for skin, hair, gut, and bone health. However, bovine is slightly cheaper and might be the better choice for those with intestinal problems.
Type 1 collagen from marine or bovine sources is the best option for hair and beauty-related needs because it is the richest source of essential amino acids like proline that can not only thicken hair, but also reduce hair loss and accelerate the speed of hair growth.
While the body naturally produces collagen, levels naturally start to decline by around age 30, so taking exogenous collagen may help combat this loss and smooth your skin. One study found that dosages as low as 2.5 to 5 grams per day for 4 weeks were successful in increasing skin elasticity in elderly women.
Marine collagen is extracted from the bones, skin and scales of fish. This is thought to be the most effective at skin and bone support. Bovine collagen comes from cows and is thought to help with joint health. Vegetarian/Vegan collagen is not 'true' collagen as it comes from non-animal sources.
Often, marine collagen is cleaner than bovine collagen, but if you get your hands on the right grass fed collagen, you can also get some fantastic results. Some people find that fish collagen is better for their skin health, and bovine collagen is more beneficial for joint health.
Both bovine and marine collagen provide the same benefits. Both are great for skin, hair, gut, and bone health. However, bovine is slightly cheaper and might be the better choice for those with intestinal problems.
In short, yes. Taken daily, clinical trials have shown a collagen supplement has the ability to slow down the body's breaking down of its own collagen. In fact, the marine collagen in Beauty Pie's Collagen Super Powder reduced it by a huge 31 per cent.
