About the Chewables Product

These unique sugarless (no glucose) vitamin C chewables are designed for all-day use, e.g. by cancer patients wanting to keep their redox levels high.

They are also a great way for your kids to get their vitamin C.

  • China-Free™: The first (and only) chewable vitamin C containing vitamin C as DSM Quali-C® (The highest quality vitamin C, manufactured in Scotland, UK.)
  • The first commercial chewable vitamin C containing both L-ascorbic acid and L-sodium ascorbate as DSM Quali-C. Note: DSM Quali-C® is certified No GMOs and tested 100% corn and gluten free.
  • Pleasant Taste: Natural cherry extracts. No artificial flavors, no MSG, no alcohol.
  • 90 tablets (servings)
The major ingredients are vitamin C and Niacin (as inositol niacinate, a non-flushing form of vitamin B3). Each tablet contains 425 mg of vitamin C and 25 mg of vitamin B3.

Each jar contains 90 tablets; one tablet per day means one jar will last three months.

Other active ingredients are xylitol, sorbitol, and cherry flavoring for taste. The reasons for each ingredient are described in the following sections.

Cancer and Vitamin C

"There was something odd about the results of the vitamin C and cancer experiments Linus Pauling reported in the 1980s: patients lived longer - much longer. Those treated with vitamin C lived an average of four times as long as control patients who did not receive vitamin C. This massive improvement was unparalleled in the history of medicine." - Steve Hickey and Hilary Roberts

These words were published by vitamin C and cancer experts Steve Hickey and Hilary Roberts in their book Cancer Breakthrough, Handbook on Vitamin C Therapy for Patients and Doctors.

Hickey and Robert's emphasize the importance of taking vitamin C all day long (or 24/7) fighting cancer; not just during the limited time one is undergoing a high-dosage intravenous vitamin C infusion.

This round-the-clock strategy increases the "redox pressure" inside tumors. However, it is not always convenient or easy to take high-dose vitamin C all day long.

The new chewables are designed specifically for this 'redox' mission and contain other anti-tumor factors that may have favorably affected the Pauling/Cameron results.

Cameron's sugar-free chewables have the following cancer-fighting features:

  1. Finest Vitamin C (as Ascorbic Acid) combined with Vitamin B3/Niacin (As inositol niacinate)
  2. Pleasant tasting without sugar.
  3. Lack of sugar helps starve cancers of glucose while providing known anti-cancer sweeteners xylitol and sorbitol
  4. Even Cherry flavor may contain anti-tumor substance (Cherry flavor added to match Cameron's formula)
  5. Niacin has both anti-AHDH and anti-cancer properties (ref: Niacin the Real Story: Hoffer/Saul)

Vitamin B3 (Niacin) and Cancer

Abram Hoffer discusses the anti-cancer properties of Niacin in the book Niacin: The Real story:

They illustrated this by treating two groups of human cells with carcinogens. The group given adequate niacin developed tumors at a rate of only 10 percent of that seen in the group that was deficient in niacin.

Did Ewan Cameron Invent a Secret Weapon Against Cancer?

The following observation made by a local medical doctor may be the "secret weapon" that may have unintentionally improved the effect of vitamin C against cancer in the Pauling/Cameron Scotland study: The addition of sorbitol and cherry flavoring!

Dear Owen,

I believe I have found more clues to how Cameron's cancer patients responded better than subsequent patients on IV/C.

While checking about something else, I came across the website of Dr. Arnold Smith of Mississippi. He explains how he had numerous conversations years ago with Dr. Cameron while he was alive. Dr Smith reports something that I never heard of in any of the published literature from that time.

The patients daily took 10g of ascorbic acid orally in large pills, but did not like it. So he and a compounding pharmacist reformulated a different procedure. They drank a solution of sodium ascorbate plus sorbitol plus cherry flavor. Well now!

That means something important to me.

It has recently come to light more and more about the low carbs diet being necessary to beat cancer. OK then, someone drinking something sweet several times daily everyday is going to tend to not crave yet more sweets. This should contribute however inadvertently to a low or lower than average carbs diet and could even be ketogenic since sorbitol is little metabolized and considered a low caloric sweetener. Furthermore, the literature supports a pro-apoptotic effect in some tumors.

Next cherry flavor contains significant amounts of benzaldehyde. This substance is notably damaging to tumors by reacting with their precious thiol groups and disrupting thiol-disulfide and redox metabolism. The sodium ascorbate may also have assisted to remove metabolic acids as most cancer patients are moderately acidotic. I have attached some relevant references.

Enjoy! and Merry Christmas!

Dr Arnold Smith wrote: The following important details are quoted from: Dr. Arnold Smith's Cancernet at the North Central Mississippi Regional Cancer Center "Ascorbic Acid Mixture" [paragraphs 5, 6 & 7]

Dr. Pauling had suggested to Dr. Cameron that 10 grams of vitamin C daily was a good dose for an initial clinical trial. Dr. Cameron, however, found that patients balked at the 10 large tablets required and often failed to take the recommended dose due to the sheer bulk of medicine. Cameron went to his pharmacist for advice.

The pharmacist suggested a liquid preparation as possibly more acceptable. Conversion of the vitamin C, also known chemically as ascorbic acid, to a non-sour liquid was accomplished by adding baking soda. A form of sugar, sorbitol, was added as a preservative and as a sweetener. A flavor, cherry syrup, was added. Dr. Cameron's patients in rural Scotland were sent back home with a several week supply of the ascorbic acid mixture which was typically dispensed in two brown one liter bottles. Refrigeration was recommended. The clinical trial was initiated.

Dr. Cameron reported dramatic improvements in median cancer survival. In addition to much longer survival, some patients experienced protracted remissions. There were survival plateaus observed in cancers which had been uniformly fatal. Cameron reported his results in the medical literature to a very skeptical and critical audience. Many physicians believed that an assertion that vitamins could treat cancer was ridiculous, and Cameron and Pauling were both subjected to harsh criticism.

Sorbitol Versus Cancers

Rapid induction of apoptosis in human gastric cancer cell lines by sorbitol.

Teramachi K, Izawa M.

Author information: Department of Biosignaling, Faculty of Medicine, Tottori University, Yonago 683-8503, Japan.

Most solid tumors, including gastric cancers, respond poorly to non-surgical treatments which are expected to induce an apoptosis-dependent involution. We hypothesize that the apoptotic machinery in solid tumors is either defective or in a suppressed condition. Overcoming the ineffective induction of apoptosis may improve the responsiveness of solid tumors to non-surgical treatments. Recently, sorbitol, a kind of hexose, has been found to be an effective inducer of apoptosis in HEp-2 cells. Therefore, it is of particular interest to examine the effect of sorbitol-treatment on gastric cancer cells. In the present study, we selected 4 gastric cancer cell lines which have been reported to exhibit different abilities in regard to apoptosis induction, and examined the effect of sorbitol-treatment on apoptosis induction. Within 3 hr after sorbitol-treatment, apoptosis was induced comparably in all cell lines examined. Cell death in MKN-1, MKN-28 or MKN-74 proceeded in a biphasic manner, while cell death in KATO-III was monophasic. The cell death partially depended on caspase activity. Treatments with sorbitol in combination with 12-O-tetradecanoylphorbol-13-acetate (TPA) markedly suppressed the apoptotic cell death, suggesting a role of protein kinase-C-dependent process. To our knowledge, this is the most rapid induction of apoptosis in human gastric cancer cells reported to date. PMID: 11232246 [PubMed - indexed for MEDLINE] 5.


The sugar-free, the sweetener xylitol is known to have anti-biotic properties and is recommended for healthier teeth. The theory is that microbes accept xylitol is as if it were sugar, but cannot survive.

The osmolyte xylitol reduces the salt concentration of airway surface liquid and may enhance bacterial killing.

Joseph Zabner*†, Michael P. Seiler*, Janice L. Launspach*, Philip H. Karp*, William R. Kearney‡, Dwight C. Look§, Jeffrey J. Smith¶, and Michael J. Welsh*‖**

Abstract The thin layer of airway surface liquid (ASL) contains antimicrobial substances that kill the small numbers of bacteria that are constantly being deposited in the lungs. An increase in ASL salt concentration inhibits the activity of airway antimicrobial factors and may partially explain the pathogenesis of cystic fibrosis (CF). We tested the hypothesis that an osmolyte with a low transepithelial permeability may lower the ASL salt concentration, thereby enhancing innate immunity. We found that the five-carbon sugar xylitol has a low transepithelial permeability, is poorly metabolized by several bacteria, and can lower the ASL salt concentration in both CF and non-CF airway epithelia in vitro. Furthermore, in a double-blind, randomized, crossover study, xylitol sprayed for 4 days into each nostril of normal volunteers significantly decreased the number of nasal coagulase-negative Staphylococcus compared with saline control. Xylitol may be of value in decreasing ASL salt concentration and enhancing the innate antimicrobial defense at the airway surface.

Children: Niacin Deficiency and Hyperactivity


Note: These tablets are too large for small children. We also recommend that children suck before chewing to soften the tablet.

These tablets are a sugar-free way for older children to obtain their daily vitamin C requirement with the important addition of Niacin.

Why Include Niacin?

Abram Hoffer, MD, PhD, was a psychiatrist who routinely prescribed high doses of niacin. This work interested Pauling who coined the term "orthomolecular" after reading one of Dr. Hoffer's books. Later, Hoffer even recommended Niacin as a possible non-drug treatment of Attention Deficit Hyperactivity Disorder (ADHD).
Hoffer's clinical observations and review of the research support his belief that Niacin can be an important preventive and possible treatment for many cancers (in conjunction with vitamin C).
Vitamin B3 and Hyperactivity. Some older literature supports the idea that Niacin deficiency contributes to Attention Deficit and Hyperactivity Disorders. Dr. Hoffer described niacin's calming effect:

"So accurately does the (Kaufman, 1949) report describe the problems of ADHD children that it is difficult to believe that vitamin B3 has been so thoroughly ignored for so long."

Dr. A. Hoffer, MD, PhD, reports on the calming effect of Niacin and its utility as a non toxic treatment for child ADHD.

From Hoffer/Saul's Niacin the Real Story pg 90,

William Kaufman treated arthritis patients with niacinamide and noticed that it was an effective remedy for hyperactivity and lack of mental focus.

Kaufman continues, "With vitamin therapy, such a patient becomes unaccustomedly calm, working more efficiently, finishing what he starts, and he loses the feeling that he is constantly driving himself . . .

If such a patient can be persuaded to continue niacinamide therapy, in time he comes to enjoy a sense of well-being, realizing that in retrospect that what he thought in the past was a superabundance of energy and vitality was in reality an abnormal "wound up" feeling, which was an expression of aniacinamidosis (niacin deficiency).

I (AWS) knew of a ten-year old by who was having considerable school and behavior problems. Interestingly enough, the child was already on physician-prescribed little bits of niacin, with a total daily dose of less than 150 mg. Not a bad beginning, since the RDA for kids is under 20 mg per day. But it wasn't enough to be effective and the boy was slated for the Ritalin-for-lunch-bunch. Dr. Hoffer suggested trying him on 500 mg niacinamide three times daily. (1,500 mg total). What a difference!
In my very first book (AH) on niacin in 1962, I discussed what little was then known of vitamin B3 as a sedative. . . . Niacin also sedated animals when a sufficient amount was administered.

Dosage Recommendations

Recommended Dosages for Cancer

The new Chewable Sugar-FREE/China-FREE™ tablets are designed to make it easier to keep the vitamin C-induced oxygen-redox pressure on the tumors.
In their book CANCER BREAKTHROUGH, Dr. Steve Hickey and Dr. Hilary Roberts stress that it is important to put pressure on cancer cells by taking vitamin C all day, every day, rather than just a few times per week during a high dose intravenous infusion.

The Hickey/Roberts dynamic flow theory predicts that the half-life of vitamin C in the blood is 30 minutes. This means that optimal vitamin C levels can be maintained in healthy people by taking 250-500 mg, or one chewable tablet, every 3 to 4 hours. (Cancer patients might metabolize more, probably not less.)

Recommended Dosages for Children

One tablet per day will better the health of most children, and 3 tablets per day may very well be optimal for most healthy children.

Dr. Frederick Klenner published his vitamin C dosage recommendations for children based on his early clinical experience:

1 gram of vitamin C daily for every year of age up to age 10.

Vitamin C Foundation Note: Dr. Klenner would have recommended 2 grams (2,000 mg) for 2 year-old, and 5 grams (5,000 mg) for a five year old, etc.

The Vitamin C Foundation currently recommends 3000 mg of vitamin C daily, or 6 tablets, optimally, 2 tablets with breakfast, one tablet for lunch, 2 tablets for dinner and 1 tablet before bed. See Our Vitamin C RDA
