I am thin and athletic, take vitamins daily (a good multivitamin with minerals, Super B, Vit C w/rosehips, 1200 mg of calcium + D. I'm also on thyroid medicine
(Levoxyl, .075) for hypothyroidism and my TSH is in
range and I'm feeling great. I exercise: power walking, push ups, yoga stretches, an occasional run. Also, like some others here, I have Raynaud's syndrome (genetic: mother and brother).
