Zinc

Also called Zinc oxide, Zinc gluconate

An essential trace mineral involved in normal macronutrient metabolism. Of the minerals in our blood sugar formula, zinc has the strongest supporting evidence.

Dose used in research Commonly 15-30 mg per day in trials

Zinc is a required cofactor across carbohydrate, fat and protein metabolism, which is the basis for the nutrient-role claim we make.

In trials, zinc showed the largest glycaemic effect of any mineral in this formula, but almost entirely in people with dysglycaemia. Once healthy participants are included in the pooled analysis, the effect falls sharply. We therefore keep our wording on the nutrient role rather than on glucose outcomes.
