I'm thinking about trying some collagen for what I understand should have hair nail and skin benefits.
I see there are supplements in tablet form and also powder form and some just seem to say collagen/beauty and others say marine collagen or collagen peptides.
Does anyone know what the best stuff is to use? I've been looking at a blue tub from vital proteins which is collagen peptides in a 20g dose of powder form.
It's about £35 for just under 600g so also looking to identify the most money savvy way of buying the recommended type.
Hope someone can help!
