6. Your wounds heal slowly
If your cuts and scrapes heal slower than usual, it might be a sign that you don’t have enough zinc in your system.
Zinc is crucial to the health of your immune system, so it is only natural that you will become more vulnerable to bacterial infections when you have zinc deficiency, hence affecting your body’s ability to heal wounds.
Other causes of slow wound healing include diabetes, rheumatoid arthritis arterial disease, or deficiency in the human growth hormone (HGH).
Before jumping to any conclusions, you must first get checked by a doctor and make sure that the cause behind the slow wound healing or lack thereof is zinc deficiency and not something else completely.
