I cannot speak on the effectiveness of this product as I couldn't get past the sour taste. This is my first time trying this product, and I was surprised how it altered the flavor of my coffee and not in a good way. Yuck!!!

Tastes awful. I have used Vital Proteins for years, which blends into my coffee with no taste. I tried this one on sale, and it tasted terrible. Had to pour out my coffee. Was refunded.

I'm sure the collagen works great but it alters the flavor of your drink. I suggest drinking it with orange juice or some other tart beverages (definitely not coffee) or chugging it down with water.

really love this. I've been buying it now into 2 lb. no flavor, no taste. mixes. fare well with anything. even bottled water and two stirs and it's gone. it's mixed

Tastes awful. I don't know if it makes my hair or nails better. I just know I will never buy again and. am sorry that I bought this. I have had other collagen powders that were not this bad

I used to order directly from Sports Research and decided to try this one instead. Taste was definitely off compared to the original. Tried it for a couple days but had to return it.

I had an allergic reaction that left my skin with itchy/ hot rashes all over my body for 3 days after one use. Please include all ingredients on the labels to avoid this in the future. I assume there is agave within that caused my reaction.

Decided to try this as a change. So disappointed! Added to my morning coffee and it made it taste sour/salty. Horrible unexpected flavor. Going to return and buy my usual Vital Proteins.

It has a sour taste in coffee that other brands do not have

I enjoy this of my morning coffee. After two weeks of consistently using my hair shedding has lightened up.
