Please can you advice, why is the best collegen to take, I’m 47 years young

Hi, I’m a fan of Totally Derma which is very good though I appreciate it is a pricey one. There are so many to choose from; what you want is a product that gives you 10,000mg of hydrolysed collagen per daily dose, and you need to take it consistently for three months in order to be able to get an idea of what it is doing for your skin/ hair/ nails/ joints. Here’s a link to some of the videos and articles I’ve done about collagen supplements.
