The power of vitamin C

Vitamin C is probably one of the best known of all micronutrients. It helps your body maintain your immune system. We get it from our diet by eating Vitamin C-rich foods like fresh fruit and vegetables. Our bodies cannot make Vitamin C or store large amounts of Vitamin C so sometimes it can be good to get a little extra by taking a Vitamin C supplement. That’s where Cal-C-Vita® can help*.

*Vitamin C contributes to the normal function of the immune system.

What does Vitamin C do?

Vitamin C helps your body's immune system function normally. As an antioxidant, Vitamin C also contributes to the protection of your cells and helps them to function normally. Vitamin C also contributes to normal collagen formation; collagen is part of the structure of your bones, teeth, gums and skin. Vitamin C plays a part in keeping them healthy.

What is Zinc and why do I need it?

Zinc is a mineral and like Vitamin C, supports the immune system, as well as the protection of cells from oxidative stress. Zinc is required for healthy growth and development. Although essential to our immune systems, we do not produce Zinc. Zinc is found in a number of foods (meat, fish, milk, dairy and cereals), as well as some food supplements such as Cal-C-Vita® Combo

What is Vitamin D and why do I need it?

Vitamin D is primarily formed through the action of UV sunlight on the skin and plays an important role in immune support. Every individual will need a different level of exposure as each of us will make Vitamin D at different rates depending on how much skin is exposed, what time of day, and how long we are out in the sun. But getting your daily dose of sunlight is not always possible. Besides getting Vitamin D through sunlight, you can also get it through eating certain foods and taking supplements such as Cal-C-Vita® Combo

How Cal-C-Vita®
helps support your
immune system



Your body is equipped with powerful natural defences and your immune system has many ways of dealing with threats from bacteria and viruses. The Immune system is made up of three main defences mechanisms; Physical barriers (skin and mucosa), cellular barriers (white blood cells) and antibodies. Nutrients such as vitamins and minerals are essential to the health and function of this complex network.

In our fast-paced world of fast food and pre-cooked meals, it may be challenging to consume adequate amounts of fruits and vegetables delivering all the vitamins and minerals we need to fully support our body functions. An inadequate intake of vitamins and minerals can negatively affect the immune system and overall health. That’s where Cal-C-Vita® comes in. Our range of Vitamin C products are designed to help support your immune system.
