Increase muscle mass
Zinc deficiency can lead to a number of health problems including growth retardation, impaired immunity, skin rashes and hair loss. Zinc supplementation can improve these conditions and also help to increase muscle mass. In one study, this supplementation increased muscle mass in people with zinc deficiency. Another study found that zinc supplementation improved strength and power output in athletes. (4)
Reduce anxiety
A new study has shown that zinc can help reduce anxiety. The study found that it can help to reduce anxiety by regulating the level of neurotransmitters in the brain. It also found that people who took a zinc supplement had lower levels of the stress hormone cortisol and were less likely to experience anxiety than those who did not take a supplement. It may also help to improve mood and cognitive function in people with anxiety disorders.
