I have not been taking it long enough to comment on the physical effects on my body, however, I enjoy taking it daily because the lemon flavor is so delicious.

Windsor Botanicals Liquid Collagen Peptides Supplement - Concentrated Hair, Skin, Nail, Joints Support - 2 oz

My hair was so short and thin I could barely put it up with a bobbi pin . I hated going anywhere because I was embarrassed. I started taking this collagen in January, once a day . By July , I had thick , shoulder length hair . I had tried every thing and nothing worked until this. It really works and definitely worth the price . One bottle lasted about 3 1/2 months

easy to use

It really has helped my finger nails grow - they are stronger. My hair is better too. I'm on my second bottle! Tastes great , lemon flavor.
