I've been taking 10,000 - 20,000 mcgs of biotin for several years and still have sinus issues. I'm guessing that something else -- in addition to the biotin -- helped Dara, the previous reviewer from 2017.
After a 7 year miserable and frustrating battle with sinusitis, my sinuses are now finally, miraculously clear!! My cure is BIOTIN! I was taking it for something else, and as a wonderful side effect, it completely cleared my sinuses! Other supplements have helped here and there, but nothing like the astounding results of Biotin!
I am currently taking 20,000 mcg. The holistic doctor I see puts people on dosages much higher than that for various health issues, so I don't think a high dose is a problem. It took about 3 days for the Biotin to completely clear up my sinuses. If you suffer from this, eliminating wheat & dairy (from a cow - goat is ok) will definitely help, too!
