Buying Guide: What to Look For
Zinc picolinate and citrate are the best-absorbed forms. Avoid zinc oxide which has poor bioavailability. If supplementing above 25mg daily for more than a few months, add 1-2mg copper to prevent deficiency. Take zinc with food to avoid nausea. The RDA is 9.5mg for men and 7mg for women, but 15-30mg is common for active individuals.
Frequently Asked Questions
What are the signs of zinc deficiency?
Common signs include frequent colds, slow wound healing, loss of taste or smell, poor appetite, and in men, low testosterone. A blood test can confirm your levels.
Can I take zinc with other supplements?
Avoid taking zinc at the same time as iron or calcium, as they compete for absorption. Space them 2 hours apart. Zinc pairs well with vitamin C and quercetin for immune support.
When is the best time to take zinc?
Take zinc with a meal to reduce the chance of nausea. If you take it with other minerals, take zinc at a different meal to avoid absorption competition.
