How to Prevent Scurvy?

Simply take in 30mg of Vitamin C per day. That's it.

In fact, in modern times scurvy is rarely seen, due in large part to the abundance of vitamin C in a wide variety of foods and beverages. Vitamin C is found in citrus fruits such as oranges, limes, and grapefruit, and vegetables including tomatoes, green pepper, potatoes and many others.

Vitamin C is easily damaged during the food preparation stage, such as during chopping, exposure to air, cooking, boiling, and being submerged in water. The amount of Vitamin C is high enough in most foods that the quantity that remains after processing is usually more than enough for a daily supply.

The recommended dietary allowance (RDA) of vitamin C varies depending upon the source, but typically anywhere from 20 to 40 milligrams per day will guarantee you a Scurvy Free lifestyle. In fact, some studies have shown that as little as 5-7 mg a day will effectively prevent scurvy, and the average American takes in approximately 72 mg a day, more than enough. Also, the liver stores enough vitamin C to last approximately 3 months, just in case.
