Another question:
Dr. Zev recommends:
Zinc 25mg (elemental) once a day (OTC)
What is meant by “ELEMENTAL” Zinc? There are so many different types of Zinc available, I want to get the best type!

Don't buy a supplement with Zinc Oxide, the absorption is so low (3%). On the chart, it looks like a lot (80% elemental Zinc) BUT you can't absorb much of it. It's 80% but mostly non-absorbable. Zinc-fortified cereals like Total, use Zinc Oxide. Total waste!
But don't exceed Dr. Z's recommendation, either. 50 mg is plenty. If you take more than that, it can interfere with the absorption of other important things (like Iron and Copper) and it could give you stomach aches.
