Citrus Fruits

Citrus fruits such as oranges, lemons, limes, and grapefruit are all high in vitamin C, a water-soluble vitamin that is essential for good health. Vitamin C not only boosts your immune system but also increases the bioavailability of nitric oxide, which refers to your body's capacity to absorb and use the molecule. Vitamin C may also boost the quantity of nitric oxide synthase, an enzyme required for nitric oxide synthesis, according to certain research.

According to research, it may also increase levels of nitric oxide synthase, an enzyme required for nitric oxide production. Citrus fruit consumption has been associated with reduced blood pressure, greater cognitive function, and a lower risk of heart disease, according to studies. This might be due to their ability to boost nitric oxide levels. To increase your intake, in addition to eating citrus fruits whole or juicing them, consider adding the zest to your salad, seafood, or fish dish.
