Many varieties of vitamin C supplements are available online and offline at your local health stores and pharmacies such as Guardian and Watsons. As consumers, we'd like to think that the vitamins and supplements we buy are almost the same. In reality, this isn't always the case.

While supplements are regulated in Malaysia, they aren’t held to the same safety standards as pharmaceuticals. Thus, it’s important to purchase supplements from reputable companies.

Some third-party organizations, such as NSF International, ConsumerLab and LabDoor test supplements for purity and label accuracy. You may want to choose a vitamin C supplement that has been tested by one of these companies.

We have done our research and shortlisted the best for you. The list is based on recommendations by third party organizations and poularity on the local search results.

Here are the best vitamin C supplements that you can buy in Malaysia today.

Cautionary Note: Most of the Vitamin C supplements come in dosages that are above the Malaysia's recommended dietary allowance (Malaysia RDA). For adults, the recommended dietary allowance for Malaysian is 70 mg/day for both men and women (Ministry of Health Malaysia).

What You May Not Know about Vitamin C

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).

How to choose your Vitamin C supplement in Singapore

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.
