Lemon juice, fresh

Fresh lemon juice is the liquid extracted from lemons. It consists mainly of water and provides vitamin C, with small amounts of carbohydrate and protein. Per 100g, it contains 91g of water, 36mg of vitamin C, 1.6g of carbohydrate and 0.3g of protein. The carbohydrate listed is entirely sugars, while fat is present only in trace amounts.

Vitamin C supports normal immune function and helps the body absorb iron from plant foods. It is also needed to form collagen, which supports skin, blood vessels and other tissues. Lemon juice is acidic, and frequent contact with teeth can contribute to enamel erosion. Full nutrient figures are shown in the tables below.
