Been using Solgar brand Gelatin for a few years & find the benefits to be exactly as claimed. The only Gelatin supplement I've come across without many primary ingredients. Solgar Gelatin has one primary ingredient: "Gelatin". This is a sign of a quality supplement that provides what it offers in the convenience of a bottled package of 250 capsules to minimize the frequency of reordering. That is a convenience I enjoy.
Myself and my mom started taking 1-2 a day and have seen some improvement in skin flexibility and nails strength. It’s been few months since we started. I also take collagen and use facial products so hard to determine effectiveness.
