So I came across this site and this post by this MD: http://drcranton.com/nutrition/Vitamin_D_autism.htm. This story is interesting in and of itself, but I'll explain below why I've posted it.

I'm going to look more thoroughly into the links, but my concern is what he says about CLO. I had tried it a while back, having purchased the very high quality Blue Ice fermented one, but it didn't math with my stomach. I put it aside, introduced some other things and will eventually get back around to it, given all the wonderful things I hear about the benefits for reducing inflammation and healing the gut lining. At the same time, I'm D deficient and have seen immense improvements with just 1000 IU D3 supplementation per day - though I may have to soon go from lanolin to lichen for my D3 for potential allergies I've explained elsewhere. So I don't want to counteract the D working in my body and on my immune system in all the complex and important ways that it does, by taking COD and reducing my serum levels due to the high vitamin A in it. I do also eat organ meats and live, chicken and cow, given how nutrient dense and wonderful they are.

Anyway, I'm sharing this due to general interest, and for this specific issue, and wondering if anyone has any thoughts.

Edit/Addition: So, for example, one question to ask is whether anyone who has been both on D3 and CLO (esp the all natural Green Pasture Blue Ice one) has had improvement and increased D serum levels during that time.
