Vitamins in Jalapenos

One jalapeno is such a small amount of food that it doesn t contribute a significant amount of most vitamins and minerals. However, one of these spicy peppers does contain 16 milligrams of vitamin C, which is 27 percent of the daily value for the vitamin. Your body relies on vitamin C to form collagen, which is an important connective tissue, and aids wound healing, immune function and iron absorption, according to the Office of Dietary Supplements. You ll also get small amounts of vitamins A and K and folate from jalapenos.
