Molybdenum will bind the copper in your system and cause copper deficiency. I would be very careful in taking this mineral. I know whereof I speak. We farmed for over 20 years. We applied commercial fertilizer to the hay fields during the first couple of years as we got a deal on it through the Conservation office. We only ran the standard N P K tests, not trace minerals. Commercial fertilizer has molybdenum in it but we didn't know that. Our land was marginal on copper to start with. The commercial fertilizer bound up the copper in the soil and caused copper deficiency in the forages for the next 20 years+ to this very day. The forages all contain excess molybdenum that causes dietary problems in any livestock we raise on the property. All this, and we're talking very low concentrations of molybdenum to do this damage. Be careful.
