What You May Not Know about Vitamin C

A local large scale study on Malaysian older adults showed that a third has vitamin C inadequacy (Fakhruddin et al. 2016).

Do you know that Vitamin C supplements can come in many forms? Supplements typically contain vitamin C in the form of ascorbic acid, which has equivalent bioavailability to that of naturally occurring ascorbic acid in foods, such as orange juice and broccoli. Other forms of vitamin C supplements include sodium ascorbate; calcium ascorbate; other mineral ascorbates; ascorbic acid with bioflavonoids; and combination products, such as Ester-C®, which contains calcium ascorbate, dehydroascorbate, calcium threonate, xylonate and lyxonate.

A few studies in humans have examined whether bioavailability differs among the various forms of vitamin C. In one study, Ester-C® and ascorbic acid produced the same vitamin C plasma concentrations, but Ester-C® produced significantly higher vitamin C concentrations in leukocytes 24 hours after ingestion. Another study found no differences in plasma vitamin C levels or urinary excretion of vitamin C among three different vitamin C sources: ascorbic acid, Ester-C®, and ascorbic acid with bioflavonoids. 

Liposomal vitamin C supplements are encapsulated in pockets of fat cells called liposomes (hence the name). Liposomal vitamin C supplements don’t use capsules or tablets or powders to deliver nutrients. Apparently this is the most effective way of ensuring the vitamins in the supplement actually get absorbed into your body.

Additionally, the Upper Limit (UL) for supplemental vitamin C — the amount most people can consume daily without negative effects — is 2,000 mg (nih.gov).

Most vitamin C supplements provide a daily dose of anywhere from 250–1,000 mg, so it can be easy to exceed the UL if you’re not careful. Be sure to read the packaging and take only the recommended dose to avoid complications.

Vitamin C may also interfere with chemotherapy, radiation treatments, or cholesterol lowering drugs (nih.gov).

That said, when used in clinical settings treating critically ill patients, very high dose vitamin C treatments are safe and not associated with significant side effects (Critical Care).

Can Vitamin C Protect You Against COVID-19?

A Malaysian retrospective study had been conducted by Health Ministry personnel from the Raja Permaisuri Bainun Hospital in Ipoh, Perak and the Kuala Lumpur Hospital, titled "Effects of High Dose Vitamin C Supplementation on Severe Covid-19 Patients In The ICU".

While findings from this study showed that high doses of Vitamin C had reduced mortality rates and resulted in shorter hospital stays, it was too small of a cohort (14 patients) to be considered as a strong study.

A rapid review report on Vitamin C (based on available evidence up to 16 November 2020) by the Malaysian Health Ministry concluded that: 

The retrieved low level of evidence suggested that IV vitamin C may have potential to be used in patients with moderate to severe COVID-19 disease. There was high level of evidence on non COVID-19 critically-ill patients which suggested that IV vitamin C shortened the length of mechanical ventilation and reduced the length of ICU stay.

A review, published December 7, 2020, in the journal Nutrients, recommended the use of vitamin C as an additional therapy for respiratory infections, sepsis and COVID-19.

In December 16, 2020, Rob Verkerk, Ph.D., founder and scientific director of the Alliance for Natural Health, announced the launch of an international vitamin C campaign in response to the Nutrients review, which "puts all the arguments and science in one, neat place."

Interestingly, many of the risk factors for COVID-19 overlap with those for vitamin C deficiency. Certain sub-groups (male, African American, older, those suffering with co-morbidities of diabetes, hypertension, COPD), all at higher risk of severe COVID-19, have also been shown to have lower serum vitamin C levels . Average plasma vitamin C levels are generally lower in men than women, even with comparative intakes of vitamin C, which has been attributed to their higher body weight.

In the first RCT (Randomised Controlled Trial) to test the value of vitamin C in critically ill COVID-19 patients, 56 ventilated patients in Wuhan, China, were treated with a placebo (sterile water) or intravenous vitamin C at a dose of 24 g/day for 7 days. The trial was originally designed for 140 subjects and was thus underpowered, with only 54 patients due to a lack of new admissions. The authors concluded that HDIVC (high dose intravenous Vitamin C) might show a potential signal of benefit for critically ill patients with COVID-19.

The largest registered trial is the Lessening Organ Dysfunction with Vitamin C-COVID (LOVIT-COVID) trial in Canada, which is recruiting 800 patients who are randomly assigned to vitamin C (intravenous, 50 mg/kg every 6 h) or a placebo for 96 h, i.e., equivalent to 15 g/day for a 75 kg person (NCT04401150). 

This protocol has also been added as a vitamin C arm in the Randomized, Embedded, Multifactorial Adaptive Platform Trial for Community-Acquired Pneumonia (REMAP-CAP; NCT02735707). The study design provides further rationale for the use of vitamin C in COVID-19 patients . 

There is also a high-dose (10 g/day) vitamin C intervention study in 500 adults is in progress in Palermo, Italy (NCT04323514).

In the UK, the Chelsea and Westminster hospital ICU, where adult ICU patients were administered 1 g of intravenous vitamin C every 12 h together with anticoagulants , has reported 29% mortality , compared to the average 41% reported by the Intensive Care National Audit and Research Centre (ICNARC) for all UK ICUs . While the authors have stated that the addition of an antioxidant in the form of vitamin C could have contributed to the lower mortality rate, it should be noted that other clinical factors and procedures could also account for the improved mortality and that the Chelsea and Westminster ICU serves a more affluent sector of the population with less deprivation on the basis of the Index of Multiple Deprivation (IMD). Deprivation, while a risk factor for COVID-19 mortality, is also a predictor of low vitamin C status. In the UK, an estimated 25% of men and 16% of women in the low-income/materially deprived population are deficient in vitamin C > 11 µmol/L .

The Frontline COVID-19 Critical Care Expert Group (FLCCC), a group of emergency medicine experts, have reported that, with the combined use of 6 g/day intravenous vitamin C (1.5 g every 6 h), plus steroids and anticoagulants, mortality was 5% in two ICUs in the US (United Memorial Hospital in Houston, Texas, and Norfolk General Hospital in Norfolk, Virginia), the lowest mortality rates in their respective counties .

At the Cleveland Clinic, researchers are enrolling people into a study to see if vitamin C or zinc — or a combination of the two — can reduce the duration of COVID-19 symptoms. Patients will be given the supplements after they have tested positive for COVID-19.

As of January 2021, more than 50 studies have been launched to investigate the benefits of vitamin C against COVID-19. There are many such studies underway and you can review the status of these trials on clinicaltrials.gov. 

Word of Caution - The U.S. Recommended Dietary Allowance (RDA) for vitamin C is 75 to 120 milligrams per day. Taking large doses of vitamin C (ascorbic acid) on a regular basis lowers your level of copper, so if you are already deficient in copper and take high doses of vitamin C, you can compromise your immune system.

While generally considered safe even in high doses, way too much vitamin C — anything above 2,000 milligrams daily (Upper Intake Level)—can cause headaches, insomnia, gastric discomfort, diarrhea, heartburn, and other issues.

Temporarily taking megadoses of vitamin C supplements to combat a case of the cold or flu is likely not going to cause a problem. 

Many vitamin C supplements that are above the US RDA are sold in the market. It’s important to seek a physician’s advice if you intend to take high dose vitamin C on a long term basis. High doses of vitamin C (over 500 mg per day) over the long-term may increase the risk of cataracts. High-dose vitamin C can also reduce the effectiveness of certain medications and interfere with certain blood tests.

To be on the safe side, you may also request for your kidney functions to be monitored.

For long-term, daily use, your best bet is to eat a diet that is full of high quality organic vegetables and fruits that are minimally processed. Not only will you get vitamin C, but you will get all the other accessory nutrients and micronutrients that are needed to optimize it.

That said, there are also several reasons to consider taking supplemental vitamin C. First, your body cannot make it. Second, most people do not get sufficient amounts from their diet and, third, your body’s requirement for vitamin C can increase 10-fold whenever your immune system is challenged by an infection, disease or physical trauma.

Editor's Note: Basically, Vitamin C is a pretty low-risk intervention. It's easy for me to sit here and say, "Unless the patient has scurvy, wait for more data." But if a loved one was in the ICU with COVID-19, would you ask for vitamin C? It's difficult to just brush it off without due consideration.

How to choose your Vitamin C supplement in Malaysia

Selecting the right vitamin C supplement depends on a variety of factors, including the form, quality, dose, and price.

You can start by considering how you’ll be using the supplement. For instance, if you prefer to take a pill, you’ll want to check out encapsulated vitamin C supplements.

If you don’t like swallowing pills or want to mix it into beverages, your best bet is to consider liquid or powdered supplements.

Next, you want to check the supplement’s quality. Evaluate whether a brand is reputable by exploring their ingredient sourcing and manufacturing standards. A good product will also be tested by third-party organizations, such as USP, Consumer Labs, or NSF International.

Take a look at added ingredients, too. If you’re trying to limit your intake of added sugars, you want to opt for a supplement that doesn’t contain sugar.

Another factor to consider is the dosage. The recommended daily amount of vitamin C for adults is 90 mg for men, 75 mg for women, and up to 120 mg for women who are pregnant or breastfeeding. However, certain medical conditions may require that you take much higher doses (nih.gov).

Children have lower vitamin C requirements, which range from 25–75mg per day, depending on their age. However, it’s not generally advised to give children a vitamin C supplement unless their pediatrician has recommended it.

Note that the Tolerable Upper Intake Level (UL) for vitamin C for men, as well as women ages 19 and above, is 2,000 mg. Meanwhile, the UL for children ranges from 400–1,800 mg, depending on age. Daily intakes at or below these amounts are unlikely to result in any adverse health effects (nih.gov).

Although vitamin C is a natural compound, getting too much of it can cause uncomfortable and potentially serious side effects.

Some of the most common reported side effects include headaches, flushed skin, nausea, and vomiting (Trusted Source).

Consuming high doses of vitamin C for prolonged periods may also increase your risk of kidney stones (Trusted Source).

Generally, high doses of vitamin C are unnecessary and could contribute to harmful side effects. Only consume high doses if your healthcare provider recommends doing so.

Finally, you want to consider your budget. Some professional-grade brands can be expensive, but keep in mind that a higher price doesn’t necessarily mean a better product. There are plenty of high quality options available at various price points.
