Lower levels of melatonin in the body have been linked to sleep problems and jet lag. Melatonin may also play a part in keeping your immune system strong.

Not having enough protein can cause a weakened immune system, making you more likely to get an infection and causing wounds to heal slower. It can also lead to muscle and weight loss. In severe cases, it may cause slow growth and skin and hair problems.

The information presented here covers some of the nutrients that may be lowered when you take certain medications. The signs and symptoms listed can be caused by other conditions. So if you have these signs and symptoms, it doesn't always mean you have low levels of these nutrients. Many things affect the level of nutrients, including your medical history, diet, and lifestyle, as well as how long you have been taking the medication. Please talk with your health care provider. He or she can best address your health care needs and see if you are at risk for low levels of any nutrients.
