The FDA has released a warning to the medical community and the public that a high biotin level can skew the results of some medical tests. According to the statement, the FDA has seen an increase in the number of reported events of biotin interference with lab tests.
As biotin is a common ingredient in hair and nail supplements including Nutrafol, we wish to assure the public that the amount of biotin in Nutrafol is safe. The biotin level in Nutrafol is not only significantly lower than the level in question by the FDA (about 100 times lower), but it is also lower than the biotin level in many other hair supplements.
• The dose currently in question by the FDA is 300 mg per day (300,000 mcg).
• Nutrafol includes 3 mg of biotin (3,000 mcg).
• Many hair products include 5 mg (5,000 mcg) of biotin, which puts Nutrafol on the lower end of the spectrum.
