TESTED FOR PURITY: Our onsite and 3RD-PARTY LAB TESTING ensures consistent batches. We also use the MAXIMUM OF ACTIVE INGREDIENTS. Other brands use inactive ingredients like silica (anti-caking) and vegetable stearic acid (flow agent). STABLE WITH LOW-PRESSURE TECH: Our chelated zinc tablets 25mg are STABILISED IN A TEMPERATURE-CONTROLLED LAB TO PRESERVE NUTRIENTS. Most brands formulate supplements using high-pressure, highly heated conditions that degrade the active ingredients. POTENT FORMULA: Many zinc chelate bis-glycinate supplements only contain 15mg of elemental zinc. Ours contains the scientifically optimum highest potency dosage of 25mg. Unlike other brands, we do not bulk out with magnesium salts as this can hinder absorption. POTENT FORMULA: Our zinc 25mg is bound with the amino acid glycine. This makes it EASIER FOR THE BODY TO ABSORB than other types of zinc (e.g. g. zinc gluconate). Our premium zinc bis-glycinate compound easily delivers more nutrients. EXPERT-DEVELOPED ZINC BISGLYCINATE SUPPLEMENT: Our zinc bisglycinate supplement, meticulously crafted by two seasoned physicians with extensive combined experience, is widely endorsed by nutritionists for their clients. This patented supplement is highly regarded for its quality.
