Orange juice is a good source of several vitamins and minerals, including vitamin C, folate, potassium, vitamin A, vitamin D, vitamin B6, and calcium. However, the most prominent vitamin in orange juice is vitamin C, which is a water-soluble vitamin that doubles as a powerful antioxidant and plays a central role in immune function. One cup of fresh orange juice contains twice the daily recommended value of vitamin C. Vitamin C supports your immune system and may be effective in fighting against the common cold. Additionally, the folate in orange juice supports healthy fetal development, and the Centers for Disease Control (CDC) suggests that pregnant women take in at least 400 mcg of folate or folic acid each day to prevent neural tube defects.
In summary, orange juice is a good source of several vitamins and minerals, including vitamin C, folate, potassium, vitamin A, vitamin D, vitamin B6, and calcium.
