How much Vitamin C is in Lemon Juice?

Lemon juice contains approximately 500 milligrams of vitamin C and 50 grams of citric acid per liter.

Aside from supplying substantial amounts of vitamin C, the main benefits of lemons relate to their seasoning potential. By adding tart fresh lemon juice and lemon zest to recipes can reduce the amount of salt needed to enhance the flavors in rice, potatoes, salads, and cooked vegetables--while adding no fat and negligible calories.

While rarely consumed on their own, lemons make a major contribution to the flavors of many foods we eat. Although you wouldn't choose this tart citrus fruit for a snack, you might well squeeze some lemon juice over a fish fillet, add a wedge of lemon to your tea, or grate some flavorful lemon zest into your favorite cookie dough. These flavor-packed fruits are loaded with vitamin C, a vitamin whose deficiency can cause scurvy.

During the California Gold Rush, scurvy was so rampant, and fresh produce so scarce, that miners were willing to pay $1 for a lemon--over $17 in today's economy (at those rates, a glass of lemonade would cost $35). But it wasn't until vitamin C was discovered in 1932 that scientists understood that it was this vitamin, not the fresh fruit itself, that protected against the disease.
