When sick what vitamins do you lack?

Vitamin C: Vitamin C is an antioxidant that helps strengthen the immune system and protect the body against infection. It is found in citrus fruits, bell peppers, strawberries, and leafy greens.

Vitamin B6: Vitamin B6 is necessary for the production of white blood cells, which help fight infection. It is found in poultry, fish, bananas, and potatoes.

Vitamin D: Vitamin D is important for maintaining a strong immune system and protecting against respiratory infections. It is produced in the skin when exposed to sunlight and can also be found in fatty fish, fortified milk, and eggs.

Zinc: Zinc is a nutrient that is essential for the function of the immune system. It is found in red meat, poultry, seafood, beans, nuts, and seeds.

Iron: Iron is necessary for the production of hemoglobin, which carries oxygen throughout the body. Low iron levels can lead to anemia, which can make you more susceptible to infection. Iron is found in red meat, poultry, seafood, beans, lentils, and spinach.

Other nutrients: In addition to the above vitamins and minerals, other nutrients such as protein, fiber, and omega-3 fatty acids can also help support a healthy immune system.
