Do Lemons Contain Vitamin C?
Lemons DO contain vitamin C.
More info: The US Recommended Daily Allowance (USRDA) of vitamin C is 75-90 milligrams a day for adults. A typical Eureka or Lisbon lemon, the two varieties commonly found in American grocery stores, contains about 20-40 mg of vitamin C, depending on size. Thus, it takes about two to four lemons to get the recommended amount of vitamin C.
The Meyer lemon, which is actually a cross between a lemon and an orange, is sweeter than the common Eureka lemon and has less vitamin C, about half that of the Eureka.
A Key Nutrient
Vitamin C plays an important role in human health. Severe vitamin C deficiency results in scurvy, a disease that was common among sailors who went for long periods without fresh fruits and vegetables. It is required for the synthesis of collagen, without it, bleeding gums, loose teeth, bleeding from mucus membranes, and even death can occur. It is uncommon now in developed countries but does occur among those who don't eat citrus fruits like lemons or other fresh vegetables or those who abuse drugs and alcohol. Smokers are at particular risk of deficiency.
So, while the question of how much vitamin C in lemons has been answered, it's important to look for ways to include the fruit in your diet. Consider squeezing a slice in your water or tea.
