Zinc's potential impact on blood pressure and vascular health

Research suggests that zinc plays a role in supporting cardiovascular health by aiding blood vessel elasticity and supporting the production of nitric oxide, which helps vessels relax and dilate. Zinc also possesses antioxidant and anti-inflammatory properties that may protect vascular health over time.

However, current evidence does not prove that zinc supplements effectively lower blood pressure in healthy adults with normal zinc levels. Potential benefits may be limited to individuals with zinc deficiencies or certain metabolic disorders, such as obesity or type 2 diabetes. Experts emphasize that zinc supplements should not be used as a substitute for prescribed medical treatments.

Daily recommended intakes are approximately 11 mg for men and 8 mg for women. Zinc can be obtained through foods such as seafood, meat, legumes, and whole grains. Excessive supplement intake may lead to side effects including nausea, stomach cramps, and copper deficiency, and may interact with certain antibiotics.
