Happy New Year! For January, all Iodine and a seaweed product from Supreme are 20% off. Iodine is an essential nutrient that regulates our metabolism. It is common for people around here to be low in Iodine. Symptoms include cold hands and feet, low body temperature, difficulty losing weight, tenderness in the chest area, loss of hair (especially for women), and the tendency to cry easily. Iodine can be important for the prevention of breast and other cancers.
