What is the recommended dosage for Zinc?

General: 8-11 mg/day (RDA); Cognitive Support: 15-30 mg/day

What are the side effects of Zinc?

Potential side effects include: Nausea on empty stomach, Copper deficiency at chronic high doses, Metallic taste, Headache.

Zinc is an essential trace mineral involved in over 300 enzymatic reactions and plays a critical role in neurotransmission, synaptic plasticity, and neurogenesis. The brain contains high concentrations of zinc, particularly in the hippocampus. Zinc deficiency has been associated with impaired cognitive function.

What dosage of Zinc has been used in cognitive studies?

Cognitive studies have used 15 mg to 30 mg of elemental zinc daily. Zinc picolinate, zinc citrate, and zinc gluconate are well-absorbed forms. The RDA is 8 to 11 mg for adults, and the tolerable upper intake is 40 mg per day. Long-term high-dose zinc may deplete copper. Consult your doctor.

What are the potential side effects of Zinc?

Excessive zinc intake may cause nausea, vomiting, abdominal cramps, and diarrhea. Chronic high-dose supplementation can interfere with copper absorption, leading to copper deficiency anemia. Zinc may interact with antibiotics and diuretics. Consult your healthcare provider for appropriate dosing.
