Here are more delicious ways to eat lots of vitamin C. Webster explains that more vitamin C isn’t necessarily better because the body can absorb only a few hundred milligrams of it at a time. Again, the RDA for vitamin C is 75 milligrams for women and 90 milligrams for men, and “any amount above this is excreted in the urine,” she says. However, if you’re taking certain medications, you’ll need to be extra cautious with vitamin C supplements. “Vitamin C supplements may interact with several types of medications such as statins, chemotherapy, and radiation,” Meyer says. “Regardless of your medical history and dosages, everyone should be sure to consult with their healthcare provider before taking vitamin C supplements.”
