Jarrow Formulas Zinc Balance combines Zinc L-Methionine and Copper Gluconate (15:1 ratio). Zinc L-Methionine allows zinc absorption with phytate and fiber in vegetables. Zinc supports immune function. Zinc Balance includes copper because supplemental zinc depletes copper. Take 1 capsule per day or every other day, preferably on an empty stomach or with a meal void of nuts, seeds, legumes, or grains to reduce phytic acid intake when taking zinc.
