Zinc plus Selenium
Dr. Mercola's Zinc plus Selenium is a mineral supplement containing three active ingredients. Each serving provides 15mg of Zinc and 200mcg of Selenium, both of which are present at dosages commonly associated with clinical research for their respective roles in health. However, it also includes Copper at 0.25mg, which is considered underdosed compared to typical recommended intake levels, and the formula lacks completeness for comprehensive mineral support. The product earned an N+ Score of 53, resulting in an 'F' grade, reflecting its below-average performance in ingredient adequacy (67%) and formula completeness (0%). Despite 100% label transparency, the imbalanced mineral profile contributes to its lower score. This product may appeal to those specifically seeking higher doses of zinc and selenium, but it falls short in providing a balanced mineral complex.
