I use this compound as it is reputed to have the lowest levels of cadmium. The zinc came in to play when I came down with COVID-19 variant BA.5. I had two-day cold when others in my group (all younger and mostly 1/3 my age) were much sicker.
I always take zinc, especially over the winter months to boost immunity. Good mgs in this brand and gluconate is a superior form of zinc as an ingredient. Zinc deficiency can cause lots of problems with hair, nails and immune system. Good quality product. Mg is good too. Zinc is a vital nutrient to keep in good supply.
Finally, a good zinc product. I got other brand, but I find the Gluconate version goes smoother in my body. The tablets is small and flat so very easy to intake. I won't take every day, but only when I feel like I am getting sick or getting cold.
