I take the ones by VitaBright and there’s a discount for first time purchase. Apparently they work best alongside other ingredients, two of which are hyaluronic acid and vitamin C. Both of these are in the ones I use. However, I on,y realised when I had started them that they are on,y Type 1 collagen, and it’s better to have type 3 in there too, particularly for joint artery health, so will probably swap to a different brand that has all of this. Hey Nutrition had type 1 and 3 collagens in it, and that was another one I considered, but the VitaBright was cheaper.
Penguin, interesting you mention hair. Apparently it doesn’t affect the hair itself, but because it improves the structure of the skin supporting the hair, it is supposed to make it look thicker. When I had my HRT review 2 days ago, the nurse said, ‘wow, look at your hair!’.
