Vitamin C’s Role in Your Immunity

Vitamin C’s Role in Your Immunity



Vitamin C is an essential nutrient that’s water-soluble, and found naturally in many fruits and vegetables. It has many functions in the body, including supporting immunity, helping to heal wounds, maintaining healthy skin and bones, aiding in the formation of collagen, and in tissue growth and repair. Vitamin C is also a powerful antioxidant that helps detoxify or cleanse the body from harmful substances.



Playing a crucial role in the maintaining of the immune system, vitamin C is usually the first thing your parents, friends and colleagues will all recommend for that nagging cough or first signs of the common cold — and here’s why the advice continues to be passed down.

When your body is fighting an infection, especially during illness, vitamin C is rapidly used up in the body due to its varied roles. Vitamin C itself not only has antimicrobial activities but it also stimulates the growth of lymphocytes, a type of white blood cell, which responds to an invading pathogen.

This integrated role of vitamin C in helping our body fight infection has made it a nutrient of interest in immune science for decades. In numerous trials, regular supplementation with at least 200 mg of vitamin C has been shown to reduce the duration and severity of cold symptoms. Among highly active people in the winter, such as skiers or skaters, vitamin C supplementation cut the occurrence of the common cold by half!


High intakes of fruits and vegetables rich in vitamin C are associated with a reduced risk of cardiovascular disease. This may be due partly to the antioxidant content of these foods, as oxidative damage is a major cause of cardiovascular disease. Vitamin C has been shown to potentially reduce atherosclerosis — or the buildup of fatty plaques inside our blood vessels — by reducing the “stickiness” of immune cells. Furthermore, vitamin C can improve nitric oxide production, a key relaxer of our blood vessels, and extend the lifespan of the smooth muscle cells in our arteries and veins.

Population studies have also supported these heart-healthy benefits of vitamin C. One of the best-known and long-running studies is the Nurses’ Health Study, which ran for 16 years and included over 85,000 women nurses. The study’s authors found that, in this population, supplementing with vitamin C was associated with a decreased risk of heart disease.


The recommended dose to prevent deficiency of vitamin C is 75 mg per day for women and 90 mg for men. Deficiency in Canada is rare due to our generally ready access to high-quality food and supplements, but the above benefits are often seen at higher doses. Supplements are available from very low doses all the way up to 2000 mg for adults. This wide range means it has a good margin of safety, and because it’s water-soluble, the body can excrete excess vitamin C in urine. That being said, it’s important to speak with your health care practitioner before making any changes to your daily regimen.

Vitamin C is broken down by heat and light, so be sure to follow storage instructions on your supplement’s label. The best place to learn more about the variety of these products is your local CHFA Member health food store, where you’ll find it in a wide range of different forms, including capsules, powders, gummies, liquids and more. Most supplements come in the form of ascorbic acid, which is often how it appears in nature, so the absorption of supplements is generally good in the digestive tract. If you’re taking high doses, spread them out throughout the day to ensure optimal absorption.

Vitamin C carries with it a wide range of health benefits, from supporting immune health to playing a role in preventing cardiovascular disease. This winter, especially if you’re highly active and enjoying the great outdoors, consider adding a vitamin C supplement to keep your body in tip-top shape.

How to Choose High-Quality Vitamins and Supplements

How to Choose High-Quality Vitamins and Supplements

Very few things are as mind boggling as shopping for vitamins and supplements. Don’t believe us? We dare you to walk into any supplement shop or browse the vitamin section of your local drugstore and not scratch your head in utter and complete confusion. With shelf after shelf stacked with so many products and brands to choose from, it’s enough to send you running to the medicine aisle for some headache relief.

To make things even more puzzling, all of these products claim to be the best, made from the highest quality ingredients, all “proven” to work—but are they really? And how would you even know? To help cut through the confusion, the experts at our vitamin store in Surrey have put together some key factors to consider when figuring out the difference between high-quality and low-quality vitamins and supplements.


NEW PRODUCT – Viva Bio Brightening C Serum

Vitamin C is critical for your body and plays an important role in maintaining healthy, resilient skin. While young skin is full of vitamin C, aging skin naturally loses this nutrient over time. Other factors like exposure to UV light, pollutants and cigarette smoke compound the decline of vitamin C, contributing to signs of aging. The good news is that you can fight back by replenishing your skin’s vitamin C levels to help to combat and even reverse time’s effect on your face.

Your Anti-Aging Rx

Taking vitamin C through a supplement or food is beneficial to your health, but to specifically target signs of aging on your face, topical vitamin C is best. In fact, applying vitamin C to the skin can be 20 times more effective than taking it orally. Topical vitamin C is sold in a wide range of products from serum to lotions. Look for products that contain between 3% and 10% of vitamin C and include the active ingredient ascorbic acid or L-ascorbic acid. Pay extra attention to the packaging – all antioxidants, including vitamin C, are vulnerable to deterioration in the presence of air and light. Unless a product is in an airtight and opaque package, don’t buy it!

Viva’s Bio Brightening C Serum has a potent amount of Vitamin C that helps combat hyper pigmentation, sun damage, dark spots caused by acne scarring, boosts collagen production, and helps brighten up your complexion.  With rosehip oil, sweet almond oil, evening primrose oil, and vitamin e, this serum helps to combat serious dark areas of the skin to help heal the scarring.

Application of Viva’s Bio Brightening C Serum:
Apply a thin layer onto cleansed or exfoliated damp face.  Massage serum into face, allow to dry 2-3 minutes. Follow with Viva anti-oxidant rich Concentrated Anti-Aging Serum or sunscreen for best results.  Pairs best with Pure Hyaluronic Acid Serum.  Night time only use recommended.

Apply topical vitamin C once a day, ideally after you’ve exfoliated to utilize vitamin C’s full properties. On rare occasions, topical vitamin C can cause some mild dryness or flaking. Counteract this side effect with a moisturizer.  We highly recommend combining our Pure Hyaluronic Acid Serum with our Bio Brightening C Serum for moisture and protection. This topical nutrient is safe to combine with all your other skin care products and even works synergistically with other antioxidants. For a super powerful anti-aging punch, combine vitamins C and E together.

What is Viva’s Bio Brightening C Serum used for?




One of the most powerful functions of vitamin C is its role in the production of collagen, a protein that gives your skin its elasticity. As you age, collagen breaks down and wrinkles begin to form. Stabilizing your skin’s levels of vitamin C can help to counteract wrinkle formation by increasing collagen production.

Age Spots

When it comes to treating age spots, you don’t need chemical peels and lasers – it turns out that vitamin C can have almost the same results! Age spots are essentially sun damage, and vitamin C is a powerful antioxidant, shown to reduce the number of sunburned cells as well as reverse age-related damage to skin. While it’s not a replacement for sunscreen, vitamin C protects against and may repair UV damage like discoloration and fine lines.


The length of time from when you start using vitamin C until you see results varies with each person. While some people see changes as soon as 2-4 weeks, it may take others 6-8 weeks to see a significant difference.
