It may be too soon to see and feel results from my first collagen use, I got the caramel creamer and have used it daily for about 10 days. During quarantine I stopped getting my hair and nails done. I noticed quite a bit of hair loss the past few months, attributed it to the stress of 2020. The first difference I've noticed is less hair loss! I was hoping my nails that I peeled acrylic off would feel stronger, but not yet. I think continued use will help, though. In addition to the physical benefits, the flavor is good and the packaging is wonderful. I'd like to see the price a little lower, thus the 4 star instead of 5 star rating.
