Collagen

I've been taking collagen for a few months but not convinced of any changes. I am on other supplements too but recently my friend gave me some Creatine to try. It's meant to improve muscle strength and power, supports muscle growth, supports muscle recovery, may support cognitive function and may support healthy aging.
It's early days yet but much of the brain fogginess that seem to plague me - seems to have improved.

Ive been taking it for 6mths and although I've not really noticed my skin is any less wrinkly my hair is another matter. Its been getting thinner over the last 4/5yrs but I now have an inch or two of new hair growth which is very noticable as I have long hair and the new growth sticks up and is fly away like a halo 😂but thats ok if I end up with thicker hair all over.

I have taken them for some time, not sure about what they achieve.
I recently, last week listened to a BBC 4 programme ‘Toast or sliced bread’. Not sure that the correct title.
However, the scientific experts didn’t seem to think taking Collagen made much difference. I’ve stopped now.
