Best Vegan Vitamin D3 Supplement

A lot of vegans have insufficient vitamin D levels according to several studies conducted in recent years.

This is in part due to the modern lifestyle where people are working long hours in the office and other people live in northern latitudes where they can only get vitamin D at certain times of the year.

For these reasons, it’s important that vegans take a daily vitamin D supplement to keep their levels optimal.

Why should vegans take vitamin D3?

Lichens are a natural source of vitamin D3 that vegans can use.

Vitamin D research has exploded over the last decade.

It used to be thought of as just important for healthy bones, but now we know that maintaining optimal vitamin D levels is super important for many reasons.

Vitamin D is a key regulator for hundreds of genes which influences everything from bone metabolism, immune system function, cellular stress response, gene transcription regulation, DNA repair, and even our longevity. It’s thought that vitamin D could help regulate up to 5% of the human genome!

The bad news: vegans have been reported in studies to have the lowest intake of vitamin D, lowest blood levels measured by 25(OH)D3 test, and have worse bone density than non-vegans.

The good news: Although there are many foods which are fortified with vitamin D2 like milk substitutes, the only source of vitamin D3 was thought to be from sheep’s wools, at least until recently. Now us vegans are also able to take the best form of vitamin D from lichens.

What is the RDA of vitamin D?

  • Adult Males – 600 IU
  • Adult Females – 600 IU
  • Adults above 70 – 800 IU

40 IU of vitamin D equals 1 microgram (mcg)

In recent years, studies have been published in peer-reviewed journals suggesting that the recommended daily allowance should be increased in order to maintain optimal levels.

In one study, 2000 IU was sufficient to raise vitamin D levels in African American women. If you have a fair skin tone, you could probably do fine with at least 1000 IU (assuming you also get some sun exposure) [1].

Frequently asked questions about vitamin D3 supplements

Below are some of the questions that people ask with regards to taking vitamin D supplements.

1. Can’t I just eat foods that are fortified with vitamin D2 instead of taking a supplement?

Good question! Although there are many vegan foods that have now been fortified with vitamin D2, the enough that you can obtain from these foods will not sufficiently raise for vitamin D blood levels to a sufficient level. Recent research suggests that 2000 IU at least is what you need to be taking daily or getting from sun exposure.

Foods which often contain vitamin D2 include soy milk, almond milk, yogurts, and different types of edible mushrooms.

If you’re already taking a multivitamin, make sure that you check if it contains a large amount of vitamin D before using vitamin D supplements. If your multivitamin contains just 1000 IU, choose a 1000 IU vitamin D3 supplement.

2. How can I tell if I am taking too much vitamin D?

While most people will be fine taking the recommended amount of vitamin D, it’s always best to consult with your doctor to measure your vitamin D levels after a few months of taking one of these supplements. This will give you a good idea of how much you should continue to take over the long term.

Unless there are very high and toxic levels of vitamin D present in the blood (which is hard to achieve in a short period of time), there might be any immediate symptoms.

There have been reports where some people have accidentally taken too much vitamin D and they have experienced symptoms such as nausea, vomiting, weakness, frequent urination, and bone pain.

3. Why should I take vitamin D3 instead of vitamin D2?

There are two forms of vitamin D: ergocalciferol and cholecalciferol. However, cholecalciferol (D3) form is far more potent and it’s is the natural form. Vitamin D2 is often used by doctor’s to treat vitamin D deficiency and it’s a synthetic form.

Studies have shown that people who take vitamin D3 are able to maintain their 25(OH)D3 levels much better than when they are taking the D2 form.

4. Do I have to take the vitamin D supplement every day?

As vitamin D is a fat-soluble vitamin, you may take it when it’s most convenient for you. This could mean that instead of taking 1000 IU per day, you can take 7000 IU once per week.

5. Should I be taking vitamin D in the summer if I spend a lot of time outside?

In the summer, a person with light skin can spend around 20 minutes in the sun around midday and generate around 10,000 – 15,000 of vitamin D.  A person with a darker skin tone will take longer to generate the same amount. In fact, many African Americans are low in vitamin D, even if they live in sunny areas.
