I've been taking a 250mg supplement of Biotin once a day for about 3 weeks before I noticed the changes in my nails! They are harder, they don't break or chip as easily. I went on vacation for 2 weeks and forgot my Biotin. Lo and behold, near the end of the 2 week vacation I had broken one nail and chipped another!
I am back on the Biotin. I've also added the de-colorized Iodine to my repertoire and will report back after a week or two. Thanks for all the great advice Earth Clinic!!!

My fingernails were soft and frequently broke. I starting taking 1000 mcg biotin twice a day, and within 2 months, they became rock solid. I stopped taking biotin for a while, and my nails returned to being soft. When I started taking the pills again, my nails toughened up. Karen
