After taking for a few weeks I noticed part of my hair that were gray grew back to original color. My nails and cuticles also look healthier. My doctor approves of taking it. Another thing, I chose the powder type instead of the tablet type because I could dissolve the powder in water and drink it down with other medication. Before I switched to the powder type, took the tablet type but I had hard time swallow many tablets in addition to my other medication. Taking powder Collagen dissolving in water is a perfect solution. I can also adjust the intake amount for my body weight. But the powder type does has stronger smell and taste.
The thing I love the best about Super Collagen is that I put it in my tea at night and I can not taste it at all but I do believe it is working on my skin and my joints. My joints do not hurt as much and the skin on my hands is looking much nicer. I have used 1 scoop per day every day for one month.
I haven't tried many other collagen brands but I do notice an improvement in my nails, hair and joint mobility since I've been using this product. Tastes fine. It's a little clumpy but I prefer that over additives.
