Zinc is a mineral that is essential for all forms of life. Zinc deficiency was first reported back in 1961, when it
was discovered that certain children absorbed so little of the mineral that they failed to grow properly.
Zinc plays important roles in human growth and development, neurological functions, the immune system, and in
reproduction. More than 85% of the total body zinc is found in skeletal muscles and bones. Zinc is also
found in small quantities in the blood plasma.
