I posted a similar reply to another thread.
I've been taking 1 tablet (500 mg I believe) a day for over a year now. The recommendation is 2. Anyways, I've seen a dramatic difference in my skin. Not near as oily or dry either. I wouldn't think it would be wise to take more than is recommended on the bottle. Too much of a good thing could be too much.
As many claim, it's good for your skin and my nails and hair have never been stronger, longer or in better shape. The fish oil is actually good for your heart. The rest just extra benefits!
