Lemon juice has been a staple in many households for its culinary and medicinal properties. The juice of a lemon, which is a citrus fruit, is rich in nutrients, particularly vitamin C, an essential nutrient that plays a vital role in boosting immunity. A single lemon, which is approximately 58 grams, contains about 53.2 milligrams of vitamin C, accounting for roughly 70% of the daily recommended intake. The high concentration of vitamin C in lemon juice makes it an excellent addition to a healthy diet, providing numerous health benefits, including enhanced immune function.
Nutritional Profile of Lemon Juice
Lemon juice is not only a rich source of vitamin C but also contains other essential nutrients like potassium, folate, and flavonoids. A 100-gram serving of freshly squeezed lemon juice contains approximately 29 calories, 9 grams of carbohydrates, and 0.3 grams of protein. The nutritional profile of lemon juice makes it an ideal ingredient for promoting overall health and well-being. The bioactive compounds present in lemon juice, such as limonene and hesperidin, have been shown to possess antioxidant and anti-inflammatory properties, further contributing to its potential health benefits.
Vitamin C and Immune Function
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a crucial role in the functioning of the immune system. It helps to stimulate the production of white blood cells, which are vital for fighting off infections and diseases. Vitamin C also acts as an antioxidant, protecting cells from damage caused by free radicals and promoting the overall health of the immune system. The recommended daily intake of vitamin C is approximately 60-90 milligrams per day for adult men and 75 milligrams per day for adult women. Consuming lemon juice regularly can help meet these daily requirements, thereby supporting immune function and reducing the risk of illnesses like the common cold and flu.

Lemon juice has also been shown to have anti-inflammatory effects, which can help reduce the risk of conditions like arthritis and other inflammatory diseases. Furthermore, the flavonoids present in lemon juice have been found to have a positive impact on cardiovascular health, helping to lower blood pressure and cholesterol levels.
