Zinc is an essential mineral and antioxidant that plays a role in cognitive function, immune health, and
more. Zinc is a cofactor for more than 300 enzymes and 1000 proteins that regulate gene expression. Zinc is
widespread throughout the body, with the highest concentrations found in the brain, kidneys, liver, bones,
muscles, and parts of the eye. Zinc picolinate is a zinc salt derived from picolinic acid. The body absorbs
this form of zinc more easily than other zinc supplements.

Zinc supports a healthy skin barrier and can improve the symptoms of acne. Individuals with acne also tend to
have lower zinc levels than individuals without it. Supplementing with zinc can reduce inflammation and the
total number of acne bumps. Zinc slows the migration of immune cells toward the skin surface, effectively
inhibiting androgens from affecting the skin.
Other Zinc Benefits
Zinc supports the healthy functioning of several organs. Zinc reduces several risk factors that can harm the
heart, such as balancing triglyceride and cholesterol levels. Zinc also supports ocular health by improving
the flow of nutrients to the eye. The retinas use those nutrients to protect themselves from damage.
Potential Zinc Side Effects
Most individuals tolerate zinc supplements well. Some may experience mild gastrointestinal side effects,
including nausea, upset stomach, vomiting, and diarrhea. Taking excessively large doses can cause serious
health effects and disrupt the absorption of other nutrients. Zinc may interfere with antibiotic efficacy if
