Play it safe & smart: Bodies are resilient in some ways at times, and they are delicate in ways at times. Products manufactured to aid our bodies can be beneficial, but if the company goes to the trouble of advising a dosage, respect them! don't take risks! it is not smart - you'd have no one to blame but yourself if there were bad results. Thinning hair is way less ugly than a very ill or dead woman.

Biotin: Biotin is a water-soluble vitamin, so excess amounts in your blood get filtered out by the kidneys and don't accumulate, so there is low risk of toxicity. Biotin is unproven in improving hair loss, so increasing doses above standard supplements is unlikely to provide any additional benefit. Biotin occurs naturally in leafy green vegetables, particularly swiss chard, and peanuts.

Thanks Dr. Wingo for the clarification & reassurance. But I still think following recommended dosages is a good habit to develop. Ask an expert 1st - not after - doubling a recommended dosage!
