Touted for its anti-aging, and skin, hair, nail, joint, and gut-supporting properties, collagen hydrolysate is one of the hottest supplements on the market right now.
But are the claims justified?
Let’s take a look at what the scientific evidence says…
Overall, reviews of the evidence show that collagen hydrolysate has anti-ageing, anti-inflammatory, anti-oxidant, and joint-supporting properties.1, 2 When taken orally collagen hydrolysate is able to enter the body and accumulate in cartilage, where it increases the synthesis of connective tissue.3 Peptides from collagen that are beneficial to skin health have also been shown to be able to enter the bloodstream,4, 5 and effectively reach the skin as a result of oral collagen supplementation.6
A trial on 56 women aged 30-55 years, showed a significant improvement in skin hydration and elasticity in those taking just 2.5 g of collagen hydrolysate daily vs placebo.7 This effect has been shown to be dose-dependent, with results improved significantly with higher doses (5 g and 10 g).8
As little as 1200 mg per day of collagen significantly improves joint pain after 6-months.9
A 10 g dose of collagen, taken daily reduces pain, and improves joint mobility and function in people with arthritis,10, 11 and reduces joint pain and inflammation in athletes.12
So, collagen hydrolysate can help you to support skin and joint health, and reduce pain and inflammation, and encourage improved joint mobility.
