Vitamin C is an essential nutrient and a powerful antioxidant. While many sorts of fresh fruit and vegetables are a great source of this vitamin, it is sensitive to heat and might decompose during cooking. Supplements are often acidic and might irritate the stomach or cause indigestion.
Patients who have undergone a gastric and/or oesophageal surgery are, on the other hand advised to eat light, cooked food and avoid raw fruit and vegetables to avoid flatulence or upsetting the stomach. Due to their condition, vitamin C supplements would probably not be the best idea either.
