Zinc

  • Supports Cellular Function
  • Supports Healthy Airways
  • Helps Balance Blood Sugar
  • Promotes a Healthy Gut
  • Improves Energy

What does the science say?

1. Supports Immunity

Zinc is an essential micronutrient that is needed for a healthy immune response. Zinc deficiency is tied to cell-mediated immune dysfunction, increased inflammation, and damage to healthy tissues (1). Research suggests that supplementing with zinc may help to improve the immune response (2).

2. Reduces Inflammation

Studies show that zinc deficiency may reduce the body’s ability to moderate proinflammatory factors like interleukin 6 (3). Chronic zinc deficiency may lead to chronic systemic inflammation and the development of inflammatory diseases like diabetes and dementia (4).

3. Alters Gut Bacteria

Zinc is required for a healthy gut microbiome. Studies suggest that zinc has the ability to improve the composition of the microbiome, decrease inflammation in the gut, and improve overall gut physiology (12).

4. Supports Respiratory Health

Zinc has a protective effect on the respiratory system. Studies show that zinc deficiency can contribute to respiratory conditions like asthma and allergic rhinitis (6). Other studies show that zinc can lower airway inflammation and improve breathing abilities in those with asthma (7).

5. Lowers Heart Risks

Low zinc levels are correlated with a higher risk of cardiovascular disease (8). Experimental studies suggest that zinc supplementation can improve myocardial recovery, reduce hypertension, and decrease risk of arrhythmias (9).

Zinc may also play an important role in diabetes management. Zinc is required for β-cell function, insulin action, and glucose homeostasis. Research indicates that supplementation may enhance insulin sensitivity and prevent diabetes, as well as stroke and other cardiovascular conditions that result from unmanaged blood sugar and obesity (10). Both in vivo and in vitro studies show beneficial effects of zinc supplementation for type-1 and type-2 diabetes (11).

6. Improves Mood

Studies show a strong correlation between zinc deficiency and depressive symptoms, as well as an improvement in mood and reduction in depression in those supplementing with zinc (14).

7. Increases Energy

Astragalus may help those with chronic fatigue and as it has been shown to improve feelings of fatigue and tiredness (17).

Studies suggest that astragalus can help fight fatigue and improve extreme tiredness, especially in those undergoing chemotherapy (18). Studies suggest that zinc may help reduce or prevent fatigue in those undergoing chemotherapy (13). 

8. Relieves Allergy Symptoms

Zinc is required for a healthy skin integrity and barrier function. As such, zinc supplementation might be beneficial for those with skin allergies like atopic dermatitis and eczema (5).

9. Improves Sleep

Research shows that zinc acts as a “sleep modulator,” potentially managing the sleep-wake cycle, improving the quality of sleep, and enhancing overall brain function (15).
