What Exactly Is Marine Collagen?
As mentioned, marine collagen is made from sustainably-sourced fish skin and scales, otherwise destined for the bin, and contains primarily Type I collagen.
“Type I collagen makes up 85 per cent of our skin collagen and the building blocks of the skin’s structure. Most other animal-sourced collagens are Type II, which can be beneficial for joints, but this does not help your skin,’’ says Mukti, founder of organic beauty brand Mukti.
“Likewise, plant ingredients can help support your collagen, but they are unable to replenish lost collagen supplies.”
Why Should It Be Included In Our Beauty Routine?
According to founder of naturopathic skin clinic Solstice Skin, Hayley Foggarty, from 25 years onward we lose two per cent of collagen from our skin each year, which can be sped up by diet and lifestyle factors including sun exposure, caffeine and alcohol intake.
“Clinical studies have proven marine collagen’s efficacy in increasing natural collagen levels and stimulating fibroblast proliferation,’’ Hayley says.
“Our fibroblasts produce collagen and elastin. Studies have shown to increase hydration, elasticity and skin density whilst decreasing skin roughness. Marine collagen helps to reduce and slow down the signs of ageing in the skin such as fine lines, skin sagging as well as brittle hair and nails.”
Is It Superior To Other Collagen Sources?
Studies show that marine collagen is absorbed 1.5 times more efficiently than other types of collagen—making it a very effective nutraceutical. Marine collagen is best for enhancing the skin's structural integrity (otherwise known as reducing saggy skin), hydration and elasticity.
Bovine collagen is recommended for skin, joints, ligaments and muscles—making it more preferable for the whole body.
“What many people don’t realise is that, as a supplement, marine collagen powders can be used similarly to protein powders, and are what I recommend instead of protein powders for those that need extra dietary protein,’’ says holistic nutrition and herbal medicine practitioner Zoe Dent.
Does It Actually Work?
Yes and err, no.
“Just like everything, results are individual, the time frame may vary due to the level of ageing and condition of skin, hair and nails," Mukti says.
“Scientific research on daily marine collagen intake shows that changes can be seen and felt as soon as four weeks onward after daily supplementation. Increasing to 2-3 serves a day may accelerate the results.”
