Is All Vitamin C Created Equal?

Too often shops put all Vitamin C supplements together but they couldn’t be more different!

Most cheap or chewable supplements use Ascorbic Acid as it’s single source of Vitamin C.

Whilst Ascorbic Acid is a good source, it needs to be buffered as the acidity from Vitamin C can lead to gut issues and may actually kill some of the good bacteria that supports the immune system.

“A huge proportion of your immune system is actually in your GI tract,” says Dan Peterson, assistant professor of pathology at the Johns Hopkins University School of Medicine.

Taking only 1 form of Vitamin C could be affecting the very gut microbial responsible for regulating the immune systems balance - defeating the purpose of taking it in the first place and wasting your money.

If you’ve ever taken a Vitamin C and felt bloated you’ve already felt your gut react to the increased acidity.

Luckily this can be solved with a simple fix...



A natural Vitamin C formula that uses scientifically proven ingredients to support immune function, gut health, energy, cognitive function and healthy aging.

What's the difference between Vitamin c2 Fx & Regular vitamin c 

Regular vitamin C often contains sugar and other fillers which can have poor effects on your kidney function. VITAMIN C2 Fx is a combination of two forms of highly soluble and absorbable Vitamin C. It is also far less acidic than many other supplements available, making it much softer on your stomach, and especially good for your little ones or grandkids. Furthermore, it’s double action, high-quality dosage means you’re getting more for less, helping you cut down on the number of supplements you’re taking.

Supporting Our #1 Immune Defender...

The immune system helps to protect us against tiny invaders (called pathogens) such as viruses, bacteria, and parasites.

The immune system is made up of specialized organs, cells, and tissues that all work together to destroy these invaders, including the spleen, lymph nodes, bone marrow and thymus.

When pathogens are detected, it triggers an immune response in the body releasing specialist immune cells, often known as White Blood Cells to fight off the invaders.

But, as we get older our immune function declines and we become more vulnerable.

Why Does Our Immune System Suffer With Age?

Scientists believe this could be due to the shrinking of a vital immune defence organ called the Thymus.

The Thymus, takes newly formed White Blood Cells from our bone marrow and matures it into the powerful defender we rely on.2 3

Over the years, the constant fighting of bacteria, toxins and viruses takes its toll.

By our 50s, the Thymus has lost 85% of its size, reducing its ability to mature pathogen-fighting white blood cells, making us vulnerable to pathogens. (Figure 1.) 4 5 16

Research Shows Natural Thymus Support

Studies show that subjects taking Vitamin C experienced significantly more immune cell production with less age-related deterioration of the thymus.

A 2015 study, published in the prestigious British Journal of Nutrition, found a “high intake of Vitamin C suppresses age-related thymic atrophy and contributes to the maintenance of immune cells.” (Figure 2.) 6

Dr Howard Petrie, from the Scripps Research Institute in San Diego, said: "We have links between Vitamin C and normal immune function, opening new avenues for potential strategies that could improve immune defences in the ageing population." 7

European Union regulators have even come out and said, “Vitamin C contributes to the normal function of the immune system.”
