Apples have the vitamins: Vitamin A, Vitamin B1(thiamine) & B2(riboflavin), Niacin, Folate, Pantothenic Acid, Vitamin B6, and Vitamins C, E, & K. There are also other vitamins â¦ in an apple, which only contain small amounts.
Vitamin C is sometimes added by fortification, because content is variable, and much of that is lost in processing. Vitamin C also helps to prevent oxidation of the product. Other vitamin concentrations are low, but apple juice does contain various mineral nutrients, including boron, which may promote healthy bones.
