Best Vitamin D Supplements in Malaysia 2020

In recent weeks and months, several publications and studies have suggested that maintaining adequate levels of vitamin D would seem potentially beneficial in fighting the COVID-19 infection.

What Is Vitamin D?

Vitamin D is a fat-soluble vitamin, meaning that it dissolves in fats and oils and can be stored in your body for a long time.

Two main dietary forms exist (Trusted Source):
  • Vitamin D3 (cholecalciferol). Found in some animal foods, like fatty fish and egg yolks.
  • Vitamin D2 (ergocalciferol). Found in some plants, mushrooms, and yeasts.
Of the two, D3 (cholecalciferol) seems to be almost twice as effective at increasing blood levels of vitamin D as D2 (ergocalciferol) (Trusted SourceTrusted Source).

Frequently Asked Questions

What Does Vitamin D Do in Your Body?

Vitamin D needs to undergo two conversion steps to become active (Trusted SourceTrusted Source).

First, it is converted to calcidiol, or 25(OH)D, in your liver. This is the storage form of the vitamin.

Second, it is converted to calcitriol, or 1,25(OH)2D, mostly in your kidneys. This is the active, steroid-hormone form of vitamin D.

Calcitriol interacts with the vitamin D receptor (VDR), which is found in almost every single cell in your body (Trusted SourceTrusted Source).

When the active form of vitamin D binds to this receptor, it turns genes on or off, leading to changes in your cells. This is similar to how most other steroid hormones work (Trusted SourceTrusted Source).

Vitamin D affects various cells related to bone health. For example, it promotes the absorption of calcium and phosphorus from your gut (Trusted Source).

But scientists have recently discovered that it also plays roles in other areas of health, such as immune function and protection against cancer (Source).

Vitamin D3 supplements appear to be more effective at raising vitamin D levels than D2 supplements. 

Vitamin D ensures that your blood levels of calcium are high enough to meet your body’s demands. However, vitamin D does not fully control where the calcium in your body ends up. That’s where vitamin K steps in. Vitamin K2 supplements have been proven to be more effective than vitamin K1. That's why most of the top vitamin D supplement brands do combine their vitamin D3 with K2.

Can vitamin D help against COVID-19

A study published in November 2020 from Singapore (CW Tan, Nutrition 2020), found that those who were started on a daily oral dose of vitamin D3 (1,000 IU), magnesium (150 mg) and vitamin B12 (500 mcg) within the first day of hospitalisation and continued up to 14 days were significantly less likely to require oxygen therapy and further intensive care.

The statement released on 2 October by the U.S. president’s physician said that in addition to the antibodies, Trump “has been taking zinc, vitamin D, famotidine, melatonin and a daily aspirin.”

Several publications and studies have suggested that maintaining adequate levels of vitamin D would seem potentially beneficial in fighting the COVID-19 infection.

A recent study, published in JAMA (JAMA Netw Open. 2020) found that persons who are likely to have deficient vitamin D levels at the time of COVID-19 testing were at substantially higher risk of testing positive for COVID-19 than were persons who were likely to have sufficient levels.


What is the Reference Daily Intake (RDI) for vitamin D?

The RDI for vitamin D is as follows (nih.gov):
  • 400 IU (10 mcg): infants, 0–12 months
  • 600 IU (15 mcg): children and adults, 1–70 years old
  • 800 IU (20 mcg): older adults and pregnant or breastfeeding women

What is the Best Vitamin D Foods?

Here is the vitamin D3 content of a few of the best food sources (nih.gov):
FoodAmount% RDI
Cod liver oil, 1 tablespoon (15 ml)1,360 IU / 34 mcg227%
Salmon, cooked, 3 ounces (85 grams)447 IU / 11 mcg75%
Tuna, canned in water, 3 ounces (85 grams)154 IU / 4 mcg26%
Beef liver, cooked, 3 ounces (85 grams)42 IU / 1 mcg7%
1 large whole egg (D is found in yolk)41 IU / 1 mcg7%
1 sardine, canned in oil, drained23 IU / 0.6 mcg4%
Although fatty fish like salmon, mackerel, swordfish, trout, tuna, and sardines are decent sources, you would have to eat them almost every day to get enough.

The only excellent dietary source of vitamin D is fish liver oil — such as cod liver oil — which contains upwards of two times the Reference Daily Intake (RDI) in a single tablespoon (15 ml).

Keep in mind that dairy products and cereals are often fortified with vitamin D (Trusted Source).

Some rare mushrooms also harbor vitamin D, and egg yolks contain small amounts.

Best Time to Get Vitamin D from Sun in Malaysia

Most studies show that approximately 10 – 25 minutes of sun exposure between 11.00 am and 2.00 pm at least twice a week to the face, arms, legs, or back without sunscreen will usually provide sufficient daily vitamin D requirements (Harinarayan, 2013Alshahrani, 2013Holick, 2007).

The amount of sun exposure needed to synthesize adequate vitamin D depends upon the type of skin, time of the day, the month of the year, and the latitude.[Reichrath, 2014] The duration needed in an individual with dark skin is about 10 times that in fair-skinned individuals.

Editor's Note: That said, UV (Ultraviolet) rays are immunosuppressive. UV rays damage the the skin and stimulate the regulatory T cells to produce the immunosuppressive cytokine. UV radiations can also lead to DNA strand breaks. 

However, a recent study from India found that despite an intense sun exposure, 90% of infants continued to have vitamin D insufficiency and needed supplementation.[Karthikeyan, 2017] This fact is often not emphasized. A similar study from New Delhi, India that was carried out in school-age children found no increase in vitamin D levels, 4 weeks following sun exposure.[Marwaha, 2016]

Farrar et al. (2013) published a study from the United Kingdom (UK) that included volunteers from South Asian countries (India, Pakistan, and Bangladesh) staying in the UK and exposed 35% of their body surface area to variable doses of UV rays in a controlled environment for 6 weeks.[Farrar, 2013] It was found that vitamin D levels rose significantly after UV exposure. However, a significant proportion of subjects still remained vitamin D insufficient. A similar study carried out in the UK by Farrar et al. (2011) found that UV exposure may correct vitamin D deficiency in white skin individuals but not in South Asian individuals.[Farrar, 2011]
Therefore, sun exposure alone may not be an adequate source of vitamin D for dark skin children and adults. Dietary supplementation of vitamin D is necessary. The commonly recommended daily dose of vitamin D is 600 IU (15 mcg) (nih.gov).

Further, the American Academy of Pediatrics (AAP) has stated that “Use of deliberate sun exposure to maintain vitamin D sufficiency is not recommended” and “Infants younger than 6 months should be kept out of direct sunlight as much as possible.”
Also, UV (Ultraviolet) rays are immunosuppressive. UV rays damage the the skin and stimulate the regulatory T cells to produce the immunosuppressive cytokine. UV radiations can also lead to DNA strand breaks.
