First time ever jumping into collagen supplements due to hair fall out issues. I decided on this brand based on their claims and hoped for the best. Its been about 2-3 weeks of somewhat consistently drinking 1-2 servings a day. It tastes great and mixes best in warm/hot water. So far seems like I'm not losing as much hair as before, which I'm happy about! I can't speak on any changes in skin since I haven't been monitoring it and have a routine I'm happy with. Hoping to eventually try a couple other flavors in the future.
