Got sulfur sensitivities? Do your cheeks turn red & blotchy when you drink wine? Try Molybdenum. Molybdenum is an essential mineral required for many signficant chemical processes in the body. Molybdenum functions as a cofactor for three enzymes in the body, one being sulfite oxidase, which helps metabolize sulfur-containing amino acids, including cysteine and methionine. Voila, protection against sulfite sensitivity, so enjoy that red wine again.
