What happens if you take biotin everyday? Biotin supplements can cause problems if you take too much. Side effects can include skin rashes, digestive upset, problems with insulin release, and kidney problems. As with any supplement, the safety of long-term or high-dose use isn’t known.
How often should you take a biotin supplement? Currently, there’s no FDA recommended dietary allowance (RDA) for biotin, meaning there’s no widely accepted recommended daily dose. The National Institutes of Health recommends a biotin dose of 20 to 30 micrograms (mcg) per day for teenagers and adults to prevent biotin deficiency.
Can you use biotin in your hair everyday? Most hair specialists recommend using biotin shampoos every time one washes his or her hair. For users with oily scalp, using a biotin shampoo daily is a good way to keep the scalp clean and the hair nourished. However, for dry and normal hair, shampooing every day is not a necessity.
