Consumer advice
This is a solid, honest product. If you suspect zinc deficiency (fatigue, poor wound healing, frequent infections), this form will absorb better than cheap zinc oxide. However, test your zinc levels first—supplementing without deficiency provides no benefit and can interfere with copper absorption. Compare to cheaper alternatives like Nature Made Zinc ($10-12 for 60 tablets) if budget is a concern; the bisglycinate form is better absorbed, but the difference may not justify the extra cost for most people. Take with food to minimize stomach upset."
