Hello... I m taking supplements at the moment to offset cold injuries in the field. My intent is to stop taking the Mg and Zn while I change to Chromium Picolinate, Lecithan and Hawthorn. Currently I take Metephormin, Sitiglyptin, Glipizide, Plavix, Rosuvastatin, Levothyroxin, Alpurinol.... Question 1: What toxicity or adverse reactions for these supplements and current meds? Question 2: Will these new supplements interact with my Winter supplements or cause adversity?
