The Everyday Benefits of Vitamin C

Vitamin C is one of the most familiar nutrients in natural health and is often associated first with immune support. But that is only one part of what this essential nutrient does.

Vitamin C also contributes to antioxidant protection, collagen formation, wound healing and the absorption of plant-based iron.[1–3] Understanding these wider roles can help you see why adequate intake matters throughout the year.

Why vitamin C matters

Humans cannot produce vitamin C, so it must be obtained regularly through food or supplementation. It acts as an antioxidant, helping protect cells against oxidative damage, while supporting important biological processes throughout the body.[2,3]

Its role in immune health is well established. Vitamin C supports both innate and adaptive immunity and is concentrated in immune cells involved in normal immune defence.[1,2] A 2023 meta-analysis of randomized, double-blind, placebo-controlled trials using at least 1 g daily found vitamin C supplementation reduced the severity of common colds by approximately 15%.[5]

More than immunity

Vitamin C is essential for collagen formation. Collagen is found throughout skin, connective tissue, blood vessels, cartilage and bone, and vitamin C also contributes to normal wound healing.[3]

It can also improve the absorption of non-heme iron, the form found predominantly in plant foods.[3] This can be particularly relevant if you follow a vegetarian, vegan or predominantly plant-based diet.

Who should pay closer attention to vitamin C intake?

Food remains the foundation of vitamin C intake.

Canadian reference values are 75 mg per day for adult women and 90 mg for adult men, while people who smoke require an additional 35 mg per day.[3,4]

People with limited dietary variety or certain conditions affecting nutrient absorption may also be at greater risk of inadequate vitamin C status.[3] Diet, lifestyle and consistency of intake can therefore help you determine whether you may benefit from additional support.

What should you look for in a vitamin C supplement?

Not all vitamin C supplements are formulated in the same way. Ascorbic acid is widely used, while mineral ascorbates combine vitamin C with minerals such as calcium, potassium or zinc and are buffered and less acidic.[3]

It is also worth considering accompanying nutrients, ingredient quality and how easily the product fits into your routine.

Where does Ener-C fit?

Ener-C combines 1,000 mg of vitamin C per sachet from mineral ascorbates, with a broader multivitamin and mineral formulation.[6] It also provides 5 mg of zinc, alongside B vitamins, vitamin E, iodine, magnesium, potassium and other minerals.[6,7]

This wider nutritional profile makes Ener-C a strong choice if you’re looking for comprehensive daily nutritional support alongside 1,000 mg of vitamin C. A Sugar-Free Ener-C option is also available if you prefer a sugar-free formulation.

Ener-C is Non-GMO Project Verified, vegan, gluten-free and caffeine-free, contains real fruit and vegetable juice powders, no artificial colours, flavours or preservatives, and is third-party tested for quality and purity.[6] Its fruit-flavoured effervescent format offers an enjoyable alternative to taking a tablet or capsule.

Looking beyond vitamin C alone

Vitamin C deserves its reputation as an important immune nutrient, but its roles in antioxidant protection, collagen formation and iron absorption make it relevant well beyond cold and flu season.

Understanding these broader benefits can help you see vitamin C as an important everyday nutrient, while Ener-C brings together high-potency vitamin C, zinc and additional vitamins and minerals in an easy-to-take format.
