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.” *

Why choose our ultra fine vitamin C from DSM?

We sell the same Ultra Fine sold by the Vitamin C Foundation but at less than half their price.

Doctor’s Best uses a cheaper grade of DSM’s Quali-C that can’t get your plasma levels of vitamin C as high due to a much larger particle size and bowel tolerance limitations:

“I strongly recommend you sell ultrafine powder labeled as world finest. There is no problem in using DSM fine powder, but there is clear difference when you go mega dose with ultra-fine powder reaching more that 10 g a day. You can sell the fine powder or crystals, but they are second or third grade (larger) at least in terms of size of the granules of ascorbic acid. Those differences result in the difference in bowel tolerance doses, which Dr. Robert Cathcart, III, insisted as the ideal dose of oral megadose Vitamin C therapy to individuals.” – Byeong Keun Ha, M.D., Ph.D.

Is 9 servings of fruits and vegetables truly enough?

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

When you consider one orange has 30mg of vitamin C, you would need 33 of them for every gram.

Many experts recommend more than 2g a day. Some, much more: up to 18g a day. (See below.)*

Gimmick Or Good For You

Not all vitamins and dietary supplements are the same. Many popular supplement brands, in fact, contain artificial additives, synthetic flow agents, chemical colorings, and 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?*

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. *

Made in the USA? Not so much

Why are the origins of our competitors ingredients hidden? Most people don’t realize but over 90% of the vitamin C on the market comes from China. That’s because packaging the ingredients in the US is enough to claim “Made” in the USA. *

Why UK Manufacturing?

No proximity to GMO corn fields.

China doesn’t have the strict quality control regulations and enforcement.
The 5 big U.S. manufacturers either use GMO corn to make their vitamin C, or repackage Chinese ingredients. *

Ultra Fine Quali-C main features
DSM’s Quali-C

We opened this company in 2013 because the best vitamin C in the world was not being sold to the public.

DSM is the only manufacturer of high quality Vitamin C, made in the UK, exclusively from non-GMO corn grown in Great-Britain.

Not all their trademarked Quali-C products are made equally.

They include a range of vitamin C powder going from standard to their  Ultra Fine Vitamin C powder.

We only sell their very best. *

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. *

The health benefits of vitamin C, also known as Ascorbic Acid include the prevention and treatment of scurvy, treatment of the common cold, boosting the immune system, lowering hypertension, treatment of lead toxicity, curing cataracts, treatment of cancer, combating stroke, maintain elasticity of the skinhealing wounds, and controlling the symptoms of asthma.

(Please see our comments below by section)

Vitamin C, or ascorbic acid, is one of the most effective and safest nutrients. It is a water-soluble vitamin. It is a powerful antioxidant for the synthesis of collagen, which helps to make blood vessels and body muscles strong. The human body doesn’t have the capacity to generate vitamin C. Therefore, it needs to be received through food and other supplements.

Important Sources Of Vitamin C *

The important sources of vitamin C are any citrus fruits, such as oranges and grapesStrawberriesraspberriescabbagescauliflower, other leafy vegetables, red pepperspotatoesbroccoli, chilies, watercressparsley, Brussels sproutscantaloupes, mange tout, and kiwi fruits are also rich sources of this vitamin. The cooking of food at low temperatures and for short times is important to keep the vitamin C preserved and beneficial in the food.

(As per Dr Fred Klenner's suggested 5g per day, you would need 166 oranges per day. Dr Robert Cathcart's oral vitamin C dosage protocol estimated 4-15g per day in 4-6 doses for healthy normal adults)

Health Benefits of Vitamin C *

The health benefits of this amazing antioxidant are explained in detail below;

Prevents Scurvy *

Scurvy is caused by an insufficient intake of ascorbic acid. The symptoms of scurvy appear due to the weakening of connective tissues, bones, and blood vessels that include collagen. Vitamin C, a powerful antioxidant, is required for the production of collagen.

Treats Common Cold *

Vitamin C enhances the immune system of our body, which protects us from colds and coughs. It facilitates the absorption of iron and therefore strengthens the body’s resistance to infection. It also fights against viruses.

Lowers Hypertension *

People with hypertension are at a high risk of developing cardiovascular diseases. The supplement of vitamin C intake helps in lowering the body’s blood pressure.

Treats Vasodilation *

Treatment with vitamin C has effectively resulted in the proper dilation of blood vessels in the cases of atherosclerosis, congestive heart failure, high cholesterol, angina pectoris and high blood pressure. Results have been found that supplements of this vitamin improve blood vessel dilation and protect cardiovascular health.

(Although we agree that Vitamin C may aid in maintaining the cardiovascular system, the quantities needed to rapidly improve severe conditions would likely be very difficult to achieve with oral doses of vitamin C. The best way to Determine the Proper Dose of Oral Vitamin C is Dr Robert Cathcart's Protocol of Titrating to Bowel Tolerance. For serious conditions Vitamin C could likely need to be administered intravenously (under medical supervision). Dr Abram Hoffer demonstrated that Vitamin C in conjunction with Niacin (in the form of nicotinic acid) may assist dramatically in Restoring Cardiovascular Health.)

Cures Lead Toxicity *

Lead toxicity is a severe health problem found mostly in children, especially in urban areas. Abnormal development and growth have been found in some children who are exposed to lead. They develop behavioral problems, learning disabilities, and also tend to have a low IQ. It may damage the kidneys and increase blood pressure in adults. Vitamin C supplements can reduce the blood lead level.

(Dr Fred Klenner's protocol has shown that lead blood levels may be reduced withVitamin C.)

Cures Cataracts *

(Eye Disorder)
Cataracts are the most common conditions of visual problems. A decrease in the level of vitamin C in the lens of the human eye has been found more common when cataracts are present. An excessive intake of ascorbic acid increases the blood supply to the ocular areas of the body.

(Studies have shown that Vitamin C may help prevent and curb the progression of cataracts. For example:

Inverse Association of Vitamin C with Cataract in Older People in India

Genetic and Dietary Factors Influencing the Progression of Nuclear Cataract)

(Comments on the sections below to come)

Treats Cancer *

Researchers have found that a high consumption of fresh vegetables and fruits have a link to a minimized risk for various types of cancer. Studies have also shown that increased consumption of vitamin C is connected with a decreased possibility of cancers of the lungs, mouth, vocal chords, throat, colon, rectum, stomach, and esophagus.

(There are differences between "minimized risk", "decreased possibility" and "Treats", The Riordan clinic in Kansas has had much success with high dose IV vitamin C, which had led the U of Kansas Med schools as well as McGill University in Montreal to add IV Vitamin C to the chemo protocols taught in conventional treatments. We certainly wouldn't recommend trying to fight Cancer with just food nor oral C )

Combats Stroke *

Vitamin C also helps in reducing the risk of stroke, a type of cardiovascular disease. A diet full of vegetables and fruits supplies a good quantity of this vitamin, which maintains the appropriate blood pressure level. It also protects the body from free radicals which could be the reason for the stroke.

Improves your Mood *

Vitamin C plays a key role in the production of neurotransmitters like norepinephrine. They affect the mood of a person, and they are critical to the proper functioning of the brain.

Boosts Immunity *

Immunity is another important benefit of this vitamin. Vitamin C is widely known for its contribution to the immune system of the body and its stimulation of white blood vessels.

Repairs Wounds *

Vitamin C also helps to repair wounds. It facilitates the growth of the connective tissues, which speeds up the process of healing wounds.

(Legally, the Author should use the word "may help" as it is illegal to claim vitamins cure, treat, prevent or control any disease (or condition). Dr Robert Cathcart who treated more than 30K patients with his oral protocol for Vitamin C dosage, claimed his surgery patients left hospital in half the time, which eventually caused his departure from surgery to become a GP where he could operate more freely.)

Controls Asthma *

Ascorbic acid also helps to reduce the symptoms of asthma. It helps to protect against the harmful effects of pollution in the human body, which often results in asthma-like symptoms.

(Legally, the Author should use the word "may" as it is illegal to claim vitamins cure, treat, prevent or control any disease. Dr Abram Hoffer MD suggested a 2 week lactose exclusion diet as a test to see if Asthma and Allergies improved.  More info on Asthma from Andrew Saul's doctoryourself.com)

Cures Diabetes *

One of the chief reasons for diabetes, as found by various studies, is low levels of ascorbic acid. Supplements of vitamin C are beneficial as a cure for diabetes, as they help in the processing of insulin and glucose.

(Again, There is quite a difference between "help in the processing" and "Cures", I have personally witnessed my mother take control of her diabetes but it took more than just oral vitamin C. She worked closely with her doctor to adjust her medication as well as was extremely careful with her diet (especially not eating late in the evening and avoiding carbs, alcohol and sugar) and walked 5km a day. There were many supplements that helped her as we had learned about on Andrew Saul's educational website doctoryourself.com, his page on diabetes listed several supplements that may be of assistance. We felt that chromium helped her considerably. We are not listing the supplements directly as that has legal implications unfortunately.  )

Prevents Heart Diseases *

(Eye Disorder)
An adequate amount of ascorbic acid is essential for the protection of blood vessels from the damage that free radicals can cause them. This could be a major cause of a heart disease called atherosclerosis. Vitamin C acts as a preventative agent of this heart disease, as well as various other cardiac problems.

(Legally, the Author should use the word "may" as it is illegal to claim vitamins cure, treat, prevent or control any disease. More info on Coronary Disease from Andrew Saul's doctoryourself.com authored by Dr Abram Hoffer MD)
