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 there is a solution.

That's why we created...


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

Vitamin C2 Fx uses Ascorbic Acid buffered with Sodium Ascorbate to achieve a gentler absorption that’s sensitive on the stomach with a pH of about 5, thus reducing acidity but still achieving the high antioxidant effect and health benefits of Vitamin C.

Vitamin C2 Fx is encapsulated in a VegeCap so you get a pure, filler, sweetener free form of Vitamin C that’s released with control.

Vitamin C2 Fx is formulated and manufactured in our MPI certified facility in Christchurch, New Zealand to ensure it’s purity and effectiveness.

Buffered to better match resting stomach acidity.

VegeCap for controlled release of pure Vitamin C.

Made in New Zealand from natural ingredients.

Frequently Asked Questions

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.

As with any dietary supplement, it is recommended that you consult with your doctor or healthcare provider before taking Vitamin C2 Fx.

Our combination is shown to support vital bodily function - including cellular tissue regeneration, immune function, nutrient and mineral absorption, growth and development of tendons, ligaments, cartilage, bones, teeth and skin - so no matter the season you can look and feel your best.
