Vitamin C supports the immune system by boosting white blood cell production (1). Studies show that vitamin C may also help to prevent infection by strengthening the skin’s barriers and improving wound healing time (2, 3).
Vitamin C has been shown to help reduce the severity of the common cold in both adults and children (4).
Vitamin C may help protect gut health by maintaining the gut barrier and preventing endotoxemia (15).
Vitamin C may also help improve weight management. Studies indicate those with high vitamin C status oxidize 30% more fat during exercise than those with low vitamin C, and those who are vitamin C-deficient may be more resistant to fat loss (16).
Studies show that vitamin C can support the cardiovascular system by relaxing blood vessels to reduce blood pressure (11). Those who take a vitamin C supplement show an average reduction in systolic blood pressure of 4.9mmHg and a reduction of 1.5mmHg for diastolic blood pressure (12). Vitamin C may also help reduce risk of heart disease by lowering LDL levels (13).
Vitamin C also improves and benefits healthy blood sugar and blood lipid levels. Studies show that vitamin C has beneficial effects on serum, insulin, serum lipids, and glycated haemoglobin (HbA1c) which may help manage diabetes (14).
Vitamin C intake is correlated with elevated mood and a reduction in anger, confusion, and depression (18).
Vitamin C significantly helps increase iron absorption, which can help improve issues like anemia and fatigue (17).
Ensuring adequate vitamin C may help improve sleep quality. Studies suggest that low vitamin C levels are linked to sleep quality and stress (19).
