Immune system

Vitamin C, also known as ascorbic acid, is a potent antioxidant, which supports the body's defense mechanism against free radicals.

Diving into our immune system a little more - immunity can be broken down into innate immunity and adaptive immunity. Innate immunity is our first line of defense - physical barriers, chemical barriers and cellular defenses. Adaptive immunity, also known as acquired immunity, is our second line of defense (think antibodies). Vitamin C can contribute to immune functioning by supporting our various cellular functions (both innate and adaptive). Neutrophils are a part of the innate immune system and are the body’s primary defenders against invading pathogens.

One study showed the link between Vitamin C and neutrophils. This study was over the course of eight weeks and had 35 participants who consumed two Gold kiwifruit a day, which was estimated to be approximately 259 mg of Vitamin C. Plasma vitamin C levels were monitored weekly and rose to saturation after one week of supplementation. Neutrophil vitamin C levels were measured at week four (baseline) and saw a significant increase at week eight (supplementation interval)(1).

Nutrition Gaps

Vitamin C is an essential micronutrient for humans and we don’t produce it in the body. Therefore, it’s important to obtain it through your diet and supplementation.

Support your healthy eating patterns by adding this beneficial nutrient. Fruits and vegetables are loaded with key nutrients such as dietary fiber, potassium and choline - they are also packed with Vitamin C. If your plate isn’t too colorful everyday, you may want to consider supplementation to help with your vitamin C intake.
