Very Satisfied :-)
My main purpose in using this product was help my skin heal from pimples that often turn into long lasting sores. Using only one tablet a day (I'm cheap! They recommend 1 tablet up to 3 times a day) I have certainly found that healing time has improved. If I have an event coming up that I really want my skin to look its best, then I increase my dosage to 2 or 3 tablets a day. It consistently appears to help.
Also I have noticed my nails, which were on the strong side before, can grow ridiculously long now.
I cannot pinpoint any changes with regards to my hair, but again, that was healthy to start with.
I don't know if it makes a difference, but I take my first tablet with breakfast.
I have been happy to recommend Silicaplex 5000 to my own friends and family, as I have been pleased with the quality and results I have experienced personally.
