Immune System

Let’s talk about another Vitamin and the Immune System:  Vitamin C.   This vitamin has been linked to many health benefits such as boosting antioxidant levels, lowering blood pressure, improving iron absorption, reducing heart disease, but we want to take a look at how it can help boost our immune system.

Here are today’s take away points:

  • The recommended dietary allowance varies according to age, sex, and life stage of healthy people.  Click here to see NIH’s RDA
    • According to NIH recommendations, my RDA is 75mg.  Here is an article from some scientists that concluded that 200mg/day is the optimum RDA in majority of adult population.
    • A tolerable upper intake limit of 2,000 milligrams per day has been established to reduce the risk of gastrointestinal complications commonly associated with higher doses of vitamin C, such as diarrhea.  However, no scientific evidence demonstrates that vitamin C administered in doses up to 10 grams per day in adults is toxic or detrimental to health. 1
  • The human body cannot produce or store vitamin C. Therefore, it’s essential to consume it regularly in sufficient amounts.
    • Vitamin C Rich Foods:  Chili Peppers, Sweet Yellow Peppers, Thyme, Parsley, Kale, Guavas, Kiwis, Broccoli, Brussel Sprouts, Lemons, Strawberries, Oranges
    • In addition to getting Vitamin C through diet, I also supplement Ascorbic Acid (aka Vitamin C) and purchase it from Thorne Research.
  • Vitamin C appears to help reduce the severity and duration of a cold.
  • Vitamin C’s role in immune function, in particular, is crucial. It stimulates the production of white blood cells, especially neutrophils, lymphocytes, and phagocytes, and promotes the cells’ normal functions, such as their ability to detect, move toward, and engulf pathogens. 1
