    Total Nothingness
    I took this MAXIMUM STRENGTH Biotin everyday for 3 months and absolutely nothing happened to my nails or hair. My hair continued to fall out and my nails grew their normal length and they were certainly no better in regards to their strength. I will continue to take them to see if anything happens. Otherwise a waste of money.

    Be very cautious when using Biotin at this dosage.

    I have been taking Biotin daily for a little under a year now - started off with 1000 mcg and moved up to 5000mcg where I stayed at for the majority of the time using this. Yes, I did notice an exceptional growth and difference in my hair and nails. My nails grew long and strong enough for others to even notice and ask if they were real or not. My hair grew out longer in what seemed to be a short amount of time.

    After seeing such great results, I decided to up my dosage to 10,000mcg. I took this every morning for about 2 months but began to notice the growth was at a standstill, and if anything seemed to be getting more coarse, brittle, and nails easily broken. (I do not style my hair with excessive heat/products, or anything different from what I was doing before). Also, I began to breakout in places I never have before such as: under my chin, around the hairline, and my neck. After searching around, I found that I wasn't the only one experiencing this. Biotin at such a high dosage seemed to be excessively producing oil that was trapped in my hair follicles, causing the breakouts.

    My results were better from taking Biotin at lower levels from 2500-5000mcg, and would not recommend taking 10,000 mcg.

    works for me
    I've been taking these since June and my hair has grown not as much as i wanted it to but it's growing and it is a lot thicker.

    i'm a nail biter and i'm noticing that my nails are growing in stronger thus making the disgusting habit of mine difficult to achieve!

    i notice a few are complaining about this dosage causing acne.biotin is a water soluble vitamin so you MUST drink PLENTY of water to prevent acne breakouts.

    I try to drink at least a gallon of water a day so i haven't experienced any break outs.. knock on wood.

    i will continue to purchase this product at sale price.
