Why Supplement Vitamin C?

Vitamin C Dosage

To Heal Like An Animal.

Why don’t most animals suffer from heart disease & heal so much faster than we do?

As Dr Robert Cathcart explains:

They make their own vitamin C, & when stressed, sick or injured, they make a lot of it!

The good news is by taking  vitamin C in larger amounts than animals produce,

we can maintain our bodies and heal even better than they can.” *

9 Servings of Fruits and Vegetables Not Nearly Enough.

Can you get the vitamin C you need from food alone?

One fresh organic orange = 70mg of vitamin C.    (14.3 oranges / gram)

Many experts recommend more than 2g a day. Some, much more, up to 18g a day. *

Why choose “Made in the UK” over “Made in the US, or China”?

In the supplement industry, packaging ingredients in the US and EU allows companies to claim their products are “Made” there.

Over 90% of the vitamin C on the market is actually repackaged Chinese. Ours is truly made in Scotland from Non GMO Corn, grown exclusively in Great Britain.

Why UK Manufacturing?

Highest purity, lowest heavy metals and most rigorous material safety standards on the market.

No proximity to GMO corn fields like there are in the US.

The 5 big U.S. manufacturers all use GMO corn to make their vitamin C. Learn More

What on Earth are GMOs ?

GMOs, (Genetically modified organisms) are plants (or animals) that have been genetically modified by splicing in DNA from viruses, bacteria, other plants or animals.

These experimental combinations of genes from different species cannot occur in traditional crossbreeding nor in nature.

The use of single strain GMO crops reduce biodiversity, which weaken our food chain and overly expose us to risks of pests and disease.

Gimmick Or Good For You

Not all vitamins and dietary supplements are the same.

Many popular supplement brands, in fact, are loaded with sugar, contain artificial additives, synthetic flow agents, chemical colorings, or even imitation vitamin compounds that your body does not recognize and cannot fully process.

So how can you know whether or not the vitamins and supplements you buy are safe and effective?   Learn More

What Our Clients Say

(These unsolicited testimonials are from actual Amazon customers who purchased our product. Links are provided to the review and the customer profiles. Their experiences and opinions are their own*)

My family and I have been using this product on a daily basis for years. Our energy levels are higher and my kids get sick much less often now. When they do, we bump up their doses and they get well again faster than they used to. Yesterday, my son was coughing like a bull, gave him half a flat teaspoon. He came to see me about 20 minutes later and said, Dad, it worked, my cough is gone!
We tried the lower grade Quali C, it took too long to dissolve. Sticking with this one, thanks for making this quality available at half the price we used to get it from the Vitamin C Foundation. For those that think this is overpriced, I guess you haven’t found out yet that “made in the USA” is actually only repackaged Chinese…

Great Product! We really like using this product especially when dosing to bowel tolerance bc there are no other additives and it’s well sourced. It is very sour by itself, but we’ve been able to make it palatable with a little bit of Stevia or Sufficient-C. For us, it has been very effective in preventing and managing common illnesses. Also very helpful for preventing and treating sunburns for adults and kids (taken orally before going into the sun). I gave my oldest 1-2g/day for 2 years and he never got sick ONCE! Seriously. I stopped this bc seems like kids should get sick a little bit. I’ve also used it as per the Klenner protocol during pregnancy and those pregnancies were consistent with what Klenner reported with his studies. The company is very responsive to requests. Overall, we have had good experience with this product and have been using it for about 4 years.

This is the BEST vitamin c powder I have ever found! It’s so fine and dissolves instantly! I have been using this supplement for years but recently started giving my kids 1-2 grams a day when school started. Three days into the school year my son came home with a bad sore throat. I gave him two grams of this C every few hours in orange juice and by morning he was feeling just fine. I will continue to use this brand and have the entire family taking it during the school year! Best brand for no GMO’s, colors or added fillers! 


Hands down the highest quality vitamin c on the market! This product has been a lifesaver for my family, and we are lucky to have found it. Nothing beats the Quali-C ultrafine powder. Considering this is DSM and the best quality vitamin c available, the price is more than fair, this product is a steal. 


Easy to take – made in UK not China. I feel more energy and confident that my immune system is improving. Friend knowledgeable in natural medicine suggested this particular brand as it is 100% pure ascorbic acid, food grade, non GMO and made in the UK. Very pleased with this product! 


This stuff is amazing!!

Helped my mom when she was having ovarian cancer & cysts and works best by far at kicking viral and bacterial infections, better than any other vitamin c I’ve tried and I have tried a ton! Hope the price stays down so it will be affordable to take on a daily basis!
