For the conversion (from acetaldehyde to acetic acid through aldehyde oxidase) to occur, niacinamide is required along with Riboflavin, iron and molybdenum. All these nutrients are used in different ratios (as we have molybdenum mineral in very small amounts and vitamin/iron in high amounts in the body). By drinking molybdenum in higher doses (as we candida patients do) we deplete iron and b2. And only regulate this enzyme to an extent, – even if there’s enough molybdenum drunk, other nutrient absence will inhibit the activity of the enzyme. And symptoms will persist (to a smaller level of course). To completely avoid acetaldehyde damage to our system this enzyme activity needs to be up regulated with the full nutrient support. But due to Candida iron supplementation is off limits. Looks like a dead end right?
