Biotin tablets from Kruidvat. Biotin provides strong hair and contributes to normal hair growth. It also keeps your skin healthy and it would support your energy level and normal fat metabolism. I don't notice much of that. I use it mainly for my hair and I notice that it does make my hair stronger. Less hair breakage. This one by Kruidvat is high dosed and you take 1 tablet once a day during the meal. There are 100 tablets in the jar and I thought it costs €3.99.
