I was reading in another forum about MSM (supplement) and how the claim is that it helps with hair, nails, and skin. Specifically that it helps tighten skin. Has anyone tried it?

Never heard of it. I do take 5,000 mg of Biotin daily. I don't think any vitamin is going to prevent saggy skin.

Never heard of that
