The initial study showed great results for taking high dose, 300 mgs, of biotin to improve progressive ms. They are running blind studies now.

The high dose is prescribed by a doctor for a compounding pharmacy to make.

It is taken along with b complex because of the cofactor balance.

Both run around a $100.00 per month and are not covered by insurance.

This is the study:

The B complex should be included with the biotin. This is one of the places to get it. I'm not sure on the dosages yet. I am still looking into it for cidp.
