I have Raynaud's and my fingers turn white, blue, and purple. I was having this problem daily. Supposedly it is related to Systemic Lupus, but I'm wondering if it isn't related to thyroid issues and the problems of converting T4 to T3.
As soon as I started taking 200mcg selenium and 50 mg zinc with a vitamin E source (usually sunflower seeds) and a stress B complex, I immediately stopped having this problem. I have read on various sites on the internet that Selenium and Zinc deficiencies cause problems with the conversion of T4 to T3. Good luck.
