People need to take 40 mg of zinc a day to be the upper limit dose for adults and 4 mg of zinc a day for infants under age 6 months. Also, you can take vitamins by food and take vitamin C supplements.
I take Zinc supplements daily, you can find them online anywhere. I buy mine from this website https://www.vitaminexpress.org/uk/ Zinc helps your immune system and metabolism, your body usually gets enough zinc from chicken or all sorts of different food sources. But when you're vegan or vegetarian, taking zinc is important.
