Almost All Ascorbic Acid Is Made In China
To be clear, we are not inferring or implying that products using vitamin C made in China are less safe. With proper manufacturing processes and quality control, the molecule of ascorbic acid will be identical regardless of where it was made.
Still though, many consumers ourselves included simply prefer to buy foods and supplements made in America, UK, and other countries which have a better reputation for both quality control and human rights.
How much is made in China? The New York Times reports 80% and that was years ago.
That percentage is likely even higher today.
Now heres the real disgusting part. A dirty secret in the supplement world is that when a product says made in the USA, that doesnt mean the active ingredient are from America.
A company can legally claim to be US-made if the actual product capsule, tablet, etc. is manufactured in this country. As far as where the active ingredients come from, that can be anywhere in the world and theres no legal requirement to disclose it to you.
In fact, many supplement brands refuse to cite the country of origin, claiming its a trade secret. Yeah right, one can guess what their real motive is for not telling you they dont want to tell you its coming from China!

What Are The Benefits Of Vitamin C As An Antioxidant
Over the years since his controversial book, Pauling has been at least partially vindicated for his belief in vitamin C. The key is the role of vitamin C supplements as potentially effective antioxidants. Antioxidants are helpful in protecting cells against damage caused by free radicals, molecules constantly produced by the body as it breaks down and metabolizes food, plus other sources like tobacco smoke, X-rays, and radiation from the sun.
A free radical is produced when an electron is lost, and since electrons must always exist in pairs, this means the single remaining electron goes looking for a partner. The problem is, it doesnt care where it gets the partner, which can result in damage to other cells that provide the second electron. This can create a cascading effect of damage as each cell that loses an electron goes searching for a replacement. Antioxidants intervene to provide an electron replacement, thus stopping the cascading damage.
Your body produces antioxidants, but more is better. Because belief in a potential antioxidant benefit of extra vitamin C is strong, this has led to recommendations for higher daily doses. The minimal recommended dosage of 90 mg can easily be met naturally with good foods. For example, a medium-sized orange contains about 70 mg of vitamin C.

Watch Out For These Fat
Here are details about vitamins A, E and K and the symptoms of overdose to look out for.
Vitamin A is a fat-soluble nutrient that is naturally present in many foods, like beef, eggs and many fruits and vegetables. An overdose of this vitamin can lead to problems with confusion, hair loss, liver damage and bone loss. It can also cause an increased risk for death and lung-associated issues for those who have a history of smokingparticularly female smokers.
Vitamin E is a fat-soluble nutrient found naturally in foods and added to some fortified foods that can help protect cells from damage caused by free radicals, such as air pollution. But taking too much of this supplement can increase your risk for bleeding and bleeding in the brain.
Vitamin K is a fat-soluble nutrient thats important for blood clotting, healthy bones and other bodily functions. Its rare that youll overdose on vitamin K by eating things like broccoli. But in supplement form, it can induce blood clots, which can lead to heart attacks and strokes, if you take too much.
Oral Ascorbic Acid Versus Zinc Gluconate Versus Both Agents Versus Standard Of Care
In an open-label clinical trial that was conducted at two sites in the United States, outpatients with laboratory-confirmed SARS-CoV-2 infection were randomized to receive either 10 days of oral ascorbic acid 8,000 mg, zinc gluconate 50 mg, both agents, or standard of care.3 The primary end point was the number of days required to reach a 50% reduction in the patients symptom severity score. The study was stopped early by an operational and safety monitoring board due to futility after 40% of the planned 520 participants were enrolled .
Patients who received standard of care achieved a 50% reduction in their symptom severity scores at a mean of 6.7 days compared with 5.5 days for the ascorbic acid arm, 5.9 days for the zinc gluconate arm, and 5.5 days for the arm that received both agents . Nonserious adverse effects occurred more frequently in patients who received supplements than in those who did not 39.5% of patients in the ascorbic acid arm, 18.5% in the zinc gluconate arm, and 32.1% in the arm that received both agents experienced nonserious adverse effects compared with 0% of patients in the standard of care arm . The most common nonserious adverse effects in this study were gastrointestinal events.

What Are The Benefits Of ‘organic’ Vitamin C Vs Supplements
This raises the question: Is supplementing with vitamin C helpful as an antioxidant? It’s hard to say. There are some modest research findings, but the results are mixed. Is this inconsistency of findings possibly due to differences in the amount of vitamin C ingested, or the quality? Or is it the source of vitamin C? In other words, does naturally occurring vitamin C provide an antioxidant that is helpful, while vitamin C synthesized in a laboratory is not?
To be sure, controversy abounds when it comes to organic versus synthetic supplements. Biochemists argue that because the biochemical structure of vitamin C can be replicated and synthesized exactly in the laboratory, the effects should be identical to naturally-occurring vitamin C. While this makes perfect sense, some experts argue that an important difference is the undetectable life force contained in natural sources that is absent in synthetic laboratory concoctions.

Can Vitamin C Help With Covid 19

Experts from Shanghai China found that all patients who received the IV treatment improved and there no one died. There were also no side effects and the stay in hospital was 3-5 days shorter. There is currently a clinical trial on the effectiveness of IV vitamin C for COVID underway in Wuhan China. Results are expected to be out in September this year.
Based on these results and their recommendations, critically ill COVID patients in New Yorks state hospital system are being given a megadose of vitamin C thats repeated throughout the day. It has been found that vitamin C levels drop significantly when a patient suffers from sepsis (an inflammatory response when the body overreacts to the infection. By administering vitamin C intravenously, it helps restore these levels.
Dr. Andrew Weber, a critical-care specialist and pulmonologist, was quoted in the New York Post as saying: The patients who received vitamin C did significantly better than those who did not get vitamin C. It helps a tremendous amount, but it is not highlighted because its not a sexy drug.

2000 mg of vitamin C per day, or at once, is the peak limit for the allowed dosage of this vitamin. Still, we dont encourage consuming that amount on a daily basis without a consultation from your doctor.

Supports The Immune System
The immune system needs vitamin C to function optimally. Dr. Thomas Levy describes this vitamin as the muscle of the immune system. Vitamin C helps with the production and function of several parts of the immune system. This includes phagocytes , leukocytes , and T-cells whose main role is to scan the body for infections and abnormalities.
Viral respiratory infections can be prevented with a megadose of vitamin C. The cells responsible for immunity accumulate vitamin C and use it to destroy invading viruses and bacteria. Research also shows that the immune system is weakened by inflammatory reactions to infections. With vitamin C, you can indirectly counter this by mitigating oxidative stress. All-in-all, vitamin C is essential for immune function and can help fight infections.
