Vitamin C and Florida Orange Juice

Vitamin C plays a key role in supporting a healthy immune system 1-4. Its importance in immunity is further supported by studies with vitamin C supplements, suggesting that it may reduce the duration and severity of cold symptoms in some people.7 Vitamin C is thought to have an anti-histamine effect,1,4,5 and may support lung function.1,6 Furthermore, the absorption of iron found in plant-based foods may increase when consumed with vitamin C.1-4

Vitamin C is an antioxidant found in food and is necessary for collagen formation, an essential component of skin, bones, gums, and cartilage.1-4  Vitamin C also helps regenerate vitamin E into its antioxidant form providing further protection against damage.1,3

Fruits and vegetables supply about 90 percent of the vitamin C in the diets of the general population.3 Oranges and 100% orange juice are one of the richest dietary sources of vitamin C8 and citrus juices are one of the most cost-effective ways to get vitamin C in the diet.16 Grapefruit juice, kale, kiwi, and cauliflower also have significant amounts of vitamin C.

Between 1999 and 2018, vitamin C consumption dropped by 23 percent on average and this was largely driven by a 48 percent decline in 100% fruit juice consumption over that same time period.15 An 8-ounce glass of 100% orange juice is an excellent source of vitamin C, containing more than 100% of the recommended Daily Value.*
