Wow, that's a lot of D! I'm weaning off of sertraline and am, instead, taking high doses of niacin. I was a bit low on D last winter so I started that up again but, in addition to a multivitamin, I only take 2000iu once a day. It has entered my mind to try to start taking it 2x/day to see what happens. The thing I read about niacin is that for depression you need to work it up to 1000mg 3x/day, which is what I'm doing now. It seems to be helping as there have been fewer and milder episodes of debilitating despair.Yes, my body has a terrible time absorbing vitamins and minerals apparently. Currently I'm taking:
Morning: Fish oil, multivitamin, 5,000iu vitamin D, CoQ10, and 200mg 5-HTP
Evening: Fish oil, calcium+magnesium, 5,000iu vitamin D, CoQ10, and 200mg 5-HTP
During the worst of the winter with no light, I was taking 15,000iu of D to help.
This is just from my own research and because of having celiac disease that I ignored for a couple years my nutrient absorption has been affected. I really want to get in to see a naturopathic doctor as it would be much safer to be in touch with someone who studies these types of treatments. I have just lost my faith in conservative medicine, which only treats symptoms and is not as concerned with helping the body heal itself. I'm sick of being told there is not much to be done about the neuropathy and fibromyalgia and am starting to take control myself.
