Vitamin C is the grand daddy of immune-supporting vitamins. Its involvement in immune function has long been known and there's more research about the immune-supporting effects of Vitamin C than perhaps any other nutrient. Concentrations of this vitamin in the body’s white blood cells (the major immune cell type of the body) become rapidly depleted during infections, making it important to consume adequate amounts of vitamin C.
Foods High in Vitamin C
Vitamin C Dosing and Safety
First, aim to get your nutrients from the vitamin-C containing foods in your kitchen. For extra immune support, take 500 to 1,000 mg throughout the day with meals and snacks. If you prefer capsules, get 850 mg vitamin C in one capsule of Uckele Bio-C.
More is not necessarily better though. Taking more than 3,000 mg at a time can lead to some GI distress. If you are acutely trying to support your body's innate resistance to pathogens, try increasing your dosage slowly according to stomach tolerance, and also try spacing your vitamin C dosage throughout the day. For example: 1500 mg vitmain C every six hours.
When you take too much vitamin C, some of the symptoms you may experience could include diarrhea, nausea, kidney stones, abdominal cramps, and pro-oxidant effects (as opposed to the beneficial antioxidant effects we get in healthy doses).
One word of caution, vitamin C can increase iron absorption and in susceptible people, this could result in iron overload.
My Final Word About Vitamin C
My final word is this...vitamin C is a powerful ingredient in our efforts to maintain optimal health and support the immune system, and we must get it from food or supplements. While you can take a vitamin C supplement, also prioritize eating vegetables and fruits rich in vitamin C. Eating real food can be even better because you're not only giving your body vitamin C, but also numerous other vitamins, minerals, phytonutrients, antioxidants, and fiber that comes along with it.
