Zinc plays a vital role in the body, especially when it comes to supporting your immune system. Below are 10 potential health benefits of taking zinc supplements:
- Colds. Studies suggest that taking syrups or lozenges containing zinc within 24 hours after the appearance of symptoms can shorten the duration of a cold.
- Infections. Zinc helps the body fight off infections and can reduce the risk of diseases such as pneumonia.
- Diarrhea. Children with diarrhea and who have a low level of zinc may benefit from taking zinc supplements, although it’s important to consult with your pediatrician before starting your child on zinc supplements.
- Wound healing. Taking zinc can help people with skin ulcers who suffer from zinc deficiency.
- Age-related macular degeneration. Studies show that taking zinc orally may delay the progression of this eye condition.
- Diaper rash and sunburn. Ointments or lotions containing zinc oxide can prevent conditions such as diaper rash and sunburn.
- Skin issues. Lack of zinc can cause issues such as acne and hair loss. To maintain normal growth and development, it's crucial to have adequate zinc.
- Sickle cell disease. People with sickle cell disease frequently have a zinc deficiency. According to studies, taking zinc supplements may help lessen the disease's symptoms. Children who took zinc experienced fewer sickle-cell crises and improved their height and weight.
- Stomach ulcers. Daily administration of 220 mg zinc sulfate reduced the size of peptic ulcers, and people who had normal serum zinc levels had better recovery. It appears that a high dose of zinc sulfate is considered necessary for maximum effect.
- Wilson's disease. According to preliminary research, zinc may help treat Wilson's disease, a condition that results in a buildup of copper in the body. Zinc decreases the amount of copper the body absorbs and therefore it may help lower copper levels in persons with Wilson's disease.
