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...

VITAMIN C2 Fx

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.

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.

What is the return policy for Vitamin c2?

We are so confident in Vitamin C2 Fx that every bottle comes with our 60 Day Money Back Guarantee. If you are not satisfied with your purchase of any Koru Nutrition products, we don't want you paying for it... even if you have taken the entire bottle!

Simply contact us within 60 days of your original purchase, and we will immediately arrange for a refund.

Check out our Return Policy page for more details.

Do I have to sign up for A SUBSCRIPTION?

Absolutely not! Subscribe & save is available on this product but it is optional.

If you order Vitamin C2 Fx every month, we recommend that you customize your own Auto-Delivery plan for your own convenience. All Auto-Delivery shipments come with a 10% discount and a full 60 Day Money Back Guarantee, no matter how many bottles you order. However, it is not required.

Is VITAMIN C2 Fx safe?

Each of the ingredients in the Vitamin C2 Fx formula has a long-standing history of safety and effectiveness.

Vitamin C can be taken with most prescription and over-the-counter medications. When taken as directed, Vitamin C2 Fx is safe, poses no short-term or long-term health risks, and is not addictive or habit-forming.

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

How Many Capsules should I take each day?

For best effect take 1-2 capsules twice a day with a glass of water.

HOW LONG WILL A BOTTLE LAST?

Each bottle contains 60 tablets. Keeping to the recommended dosage this will last you 15-30 days.

SHOULD I ONLY TAKE VITAMIN C IF It's Winter or I'm Sick?

The benefits of Vitamin C are unparalleled although our bodies don’t produce or retain Vitamin C on its own so we need to ingest and absorb it through other means. A natural immune system booster bar none, it is essential to many body functions, not the least of which is the growth, development, and repair of all body tissues. 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.

How soon will my order arrive?

Currently, we ship all orders from Christchurch, New Zealand, so delivery times depend on the country and region we are shipping to. Usually orders arrive in 3-5 working days.

With winter approaching & the Covid19 pandemic on our door steps I thought it was time to boost my immune system. Koru Nutrician offered an immune booster package which included vitamin C2 Fx so I decided to try. I have found it has definitely helped to ward off the winter colds and now have a supply to see me well into spring.

Mary B.

Narina H.

I am very haappy with my purchase. thank you

Kathleen P.

I have been taking Koru Vitamin C for a few weeks now to boost my immune system. In the last two weeks I have twice experienced what I thought was the beginning of a cold - runny nose, sneezing, feeling a bit off colour. Each time I felt that way all day. But both times I woke the next day feeling fine. I am hoping the vitamin C was at work here helping my immune system deal with the symptoms.

Robyn M.

I feel more energetic and am sleeping much better. Awesome product.

Leigh S.

I take Vitamin C daily in order to help with the absorption of Marine Collagen which I take to help with my Osteoarthritis. These products I have taken continuously both prior to double total knee replacement surgery and following, and I believe they have helped me to keep mobile. I also love that they are produced right here in NZ!

Deidre T.

Great product feeling a lot better

Sandi H.

I was given the Relief Fx as a Christmas present and since then I have been hooked. I swim about 20km a week and have been suffering from shoulder pain. Relief Fx has helped ease that pain as long as I apply it straight after swimming and again before bedtime.

Marie R.

Robyn C.

A very good product

Bryan H.

Excellent product has a great healing effect

Jan A.

I purchased 4 bottles of Vitamin C2 Fx just as we were going into Level 4 lock-down for Covid-19. I was so grateful to have it as I usually rely on NZ organic (if I can get it) citrus fruit, mainly mandarins and oranges to keep up my Vit C count. The only fruit that was on sale was from the USA; they were so dry and tasteless and had obviously been sprayed, I couldn't bring myself to buy any more. So, having the Vit C supplement is a godsend. I can't recommend it enough. Plus an added bonus, is the amazingly friendly, helpful and caring team keeping in touch and updating me on specials is really comforting in these unprecedented times.

Joan H.

I am 78 tomorrow and love all my products Vit. C , Joint fx, and collagen regards Joan

phyllis c.

I suffer with sore neck and shoulder I still a lot of pain I've been on my fx ones as they have helped my knees my partner has had great benefits many thanks

Simon M.

I have ordered 2 products so far, the Relief Fx and Vitamin C2 F x. I had a wart on my right wrist (over 20 odd years) and while using Relief Fx onmy fingers and wrist unnoticed by me the wart had disappeared. I cannot recall how many times i had used the product or whether the product actually worked on the wart. I must also add that at times i was using cocoanut oil to massage my legs prior to using Relief Fx. Perhaps combination of the 2 worked. Who knows?: cheers Simon Marama.

Leigh S.

I take Vitamin C2 FX daily in order to get better absorption of the Marine Collagen+ that I also take daily. I have taken both for some time now in conjunction with Joint FX for arthritic problems, and I am confident that these products helped to keep me mobilised leading up to and following bi-lateral knee joint replacement surgery which I had 17 months ago.

a Anne d.

I cannot really tell but think it is doing me good. Have other medications and must be careful that it does not clash with those. On the whole quite satisfied with all your products.

Colleen G.

Bought vitamin c fx as have trouble with my immune system. Have found taking one vitamin c night and morning no sore throats. It works well.

Joanne D.

Just needed to give my self a extra boost with what’s happening in the world right now easy to purchase quick delivery and no issues taking there products

Helene B.

Your Vitamin C makes a wonderfully refreshing drink every morning. I am confident that it is benefiting us enormously

Christine W.

We have been taking it for a short time but feel comforted that we are covered health wise during Covid19. Koru has very good products my husband takes JointFx and swears by it so it was a no brainer to get out VitC from the same company. Thankyou.

Chrissy D.

Purchased the vitamin C to try and help boost my immune system. Just done one month on it and at this time with me working through Covid19 I have found I am still feeling great, even with working 46 hours a week in the supermarket amongst customers.

Lynette H.

I am using the VitC for protection at this time I usually get a dry cough in the change of season, still have but not as bad and hoping that it will completely go away

Kathleen B.

I received it promptly. I have been taking it everyday and am feeling fine. But have been in lockdown while taking it so cant say for sure how good the Vitamin C is.

Peter S.

This Vitiam C is easy to take and I like the fact you do not get a horrid artificial taste in your mouth after taking it

Margaret L.

Have got my husband taking the vitamin C as well, hope it benefits us both for winter.

Tongsiew O.

Best thing since sliced bread

Glenda C.

I have been using this vitamin c for a couple of years now. I have never had a cold since, even though I've been around school children with colds and bugs. I'm impressed!

Katy L.

I have been taking this product daily for the last 2 winters and wouldnt be without it. I have not been sick at all over this period and if I do feel a cold or sniffle coming on I take extra tablets and have found that this completely wiped out whatever bug or virus was trying to get into my system. I also love the fact that you get what you pay for ...no fillers or preservatives!

Millie L.

Absolutely love the Vitamin C!! I take 2 capsules a-day and if I can feel a cold coming on then I will take four and straight away I notice I start to feel 10x better! I had two winters in a row when I went to the UK to spend time with my nieces and nephews and didn't get sick the whole time I was there - I swear it was down to the Vitamin C2 Fx. Thank you Koru Nutrition :)

Anne H.

Great service, excellent product THANKYOU.

Richard W.

I started taking pure Velvet Fx , Vitamin C2 Fx and Joint Fx..I have managed to get of very strong pain killers from my GP ...no more brain fog

Glenda C.

I have taken this all winter and not caught a cold or anything else. It makes me feel like I have a strong immunity, and I must have as I'm very well

Linda B.

I'm presently using this product and must say this is working well for me. This is helping me with the inflammation I have been experiencing in my joints, I will purchase again.

Amanda B.

Vitamin C is an amazing vitamin. Not only will high quantities of Vitamin C help the body fight colds and other illnesses, but it improves allergies. When we kept bees, we learned a megadose of Vitamin C would eliminate the swelling associated with bee stings or prevent swelling all together if taken right away. Our bodies cannot manufacture Vitamin C. We must get it from food or supplements. From my reading about Vitamin C, we probably need much more than most people get. The government recommendations are only based on what it takes to prevent scurvy rather than what it takes to be healthy in general. These days the soil on most farms is so depleted that it is pretty much impossible to get the nutrition we need from food alone so supplements are a necessity for good health. However, not all supplements are the same. Many cheaper supplements contain synthetic vitamins our bodies cannot use. When I tried Koru's vitamin c I was blown away by how good I felt afterward. Being in a capsule means there's no need for fillers and other useless ingredients.

Joyce T.

I have been using joint Fx The aches in my joints have improved greatly especially the knees Will order again

Mike K.

They are great,still no flu.

Wendy G.

This is also an incredible product,I've had dermatitis on palms of my hands but since taking this product my dermatitis has cleared its such a relief for me

Neil Anthony

Vitamin C cleanses I take this for doing vitamin c flushes, it's much easier on my system than straight ascorbic acid and does the job. Sadly more expensive than supermarket but you get what you pay for.

Shannon B

Great Vitamin C Supplement Gentle on stomach, You can usually tell a good Vitamin C product from a bad one if you drop the contents of the capsule and water and stir it a dozen times, This 1 almost completely disolves where others dont disolve for me, I will also be using it when I take a bath to kill the Chlorine in the water :) also great has no unnecesary fillers or binders some which can be unhealthy for you. highly recommend it.
