Here’s another daily tip from your local dermatologist.
Biotin and hair. Biotin and nails. What does it do? You know, we really don’t know, but it seems to be very common advice that if you have thinning hair or brittle nails, take some biotin. Now we don’t really know how much biotin you should be taking, and we don’t really know if it works. So my advice to you is, you could take it, but realize that you might just be making your urine more expensive.
One thing to be certain of though, is that if you are taking biotin, an over-the-counter B Vitamin, you have to let every physician know that you’re on it before any lab test is done, because it will skew or distort that lab test, and if they aren’t aware of that, they might be telling you that everything is okay, when in fact it’s just that the lab test wasn’t picking up on what was wrong.
