Vitamin C is one of the safest and most effective nutrients, experts say. Though it may not be the cure for the common cold, the benefits of vitamin C may include protection against immune system deficiencies, cardiovascular disease, prenatal health problems, eye disease, and even skin wrinkling. The tolerable upper intake level (or the maximum amount you can take in a day that likely won’t cause harm) is 2000 mg a day for adults.
Vitamin C has received a great deal of attention, and with good reason. Higher blood levels of vitamin C may be the ideal nutrition marker for overall health. The more we study vitamin C, the better our understanding of how diverse it is in protecting our health, from cardiovascular, cancer, stroke, eye health and immunity to living longer.
It’s an antioxidant and essential nutrient that has many functions. For example, it helps produce collagen, reduce oxidative stress, and enhance wound healing.
Fresh fruits and vegetables are good sources of vitamin C. Some people take supplements, but it is always best to check with a healthcare professional first to make sure they are safe to use.
