Well after a call with Dr. Woeller, here is what Eric is doing:
Biotin, a sulphur containing B vitamin, helps metabolize fats & amino acids. Biotin deficiency can manifest as hair loss, dry scaley skin (even cradle cap in infants), dermatitis, even nausea. He is taking 5 - 10 mg per day
Zinc - 100 mg
Essential Fatty Acids (EFA) daily in the form of Cod Liver Oil from Carlson's.
And we are looking into a niacinimide cream as well. And our friend Tom suggested sulphur soap, we need to look into that as well. Given that Biotin is a sulphur containing B vitamin, it may not be a bad idea to hit it from the inside and outside. Eric is logging his supplements and taking pictures of his hands to document what is working. So right now it is just the supplements, no cream or soap and a STRICT adherence to a gluten free diet. 2 nights ago he ate a small piece of garlic bread, the next day his hands were once again cracking and bleeding.
These recommendations are for my husband, please do not use these as a standard and always consult your own doctor/practitioner before starting any new supplements (there's my disclaimer).
