Your Ultimate Guide to Vegan Vitamin D Sources & Supplements

If you're concerned you're not getting enough vitamin D on a plant-based diet, it's important to keep in mind that most vitamin D deficiencies are not caused by diet alone. In fact, the most common cause is a lack of exposure to sunlight. Known as the 'sunshine vitamin', vitamin D can be naturally synthesized by the human body when our skin is exposed to ultraviolet light.

Who Is At Risk of a Vitamin D Deficiency?

Many people have trouble absorbing enough vitamin D through exposure to sunlight due to their darker skin tones (larger amounts of melanin in the epidermis reduce the skin's ability to produce vitamin D from sunlight), geographical region, or certain disorders.

A 2011 study found that almost 42% of the US population had insufficient levels of this essential vitamin. Among these individuals, around 82% were black, and almost 70% were Hispanic. Vitamin D deficiency was also more common among those who suffered from hypertension, obesity, or had low HDL cholesterol levels.


How To Obtain Vitamin D Safely from Sunlight

Did you know wearing sunscreen can reduce your vitamin D absorption by over 90%? This is because vitamin D synthesis can only take place when a steroid in our skin called '7-dehydrocholesterol' is broken down by the sun's UVB light. This process can only occur after a few hours or minutes of unprotected sun exposure, depending on your skin tone and weather conditions. If these rays are blocked, your skin will not be able to produce the nutrient.

That said, you should always wear sunscreen if you'll be exposed to the sun's rays for prolonged periods of time! To obtain enough vitamin D safely from the sun, try to limit daily unprotected sun exposure to just 15 minutes if you have light skin, or to a few hours if you have darker skin. Alternatively, you can obtain your vitamin D through food or supplements.

It's true that this nutrient is more bioavailable and abundant in animal sources than in plant food sources. Many foods are also fortified with vitamin D, like cereals, milks, orange juice, and others. However, these foods often contain a non-vegan source of vitamin D. So, vegans may be at risk for vitamin D deficiency if they cannot synthesize enough through exposure to sunlight. Keep reading to find out how you can ensure optimal levels of vitamin D through a vegan diet!


Why Do I Need Vitamin D?

Vitamin D is essential for absorbing enough calcium and for keeping bones healthy and strong. It also helps us maintain healthy blood calcium levels so our parathyroid glands can avoid 'borrowing' calcium from our skeleton to keep them in the normal range. So, it's a must-have for bone health. Some common signs and symptoms of vitamin D deficiency include fatigue, bone pain, muscle pain/discomfort, and depression.


Vitamin D2 vs. Vitamin D3

There are currently two known types of vitamin D. Vitamin D2 (ergocalciferol) can be obtained naturally in small amounts via certain types of mushrooms, and is the most common type of vitamin D used to fortify vegan foods. However, vitamin D3 (cholecalciferol) is the kind our body synthesizes through exposure to sunlight. This is also the form of vitamin D found in animal foods like milk, oily fish, eggs, cheese, beef liver, and others.

Although both forms carry out the same functions, studies have shown that vitamin D3 is the more active form of vitamin D, and the preferred choice for supplementation. For this reason, researchers have developed a vegan form of cholecalciferol derived from lichen! This is the type of vitamin D3 used in many vegan supplements today.


How Much Vitamin D Do I Need?

The amount of dietary vitamin D you need depends on various factors, like how much sun exposure you receive, your age, and other variables like certain health conditions or disorders. However, the FNB has based their RDAs on individuals who receive minimal or limited sun exposure. So, check out your optimal daily vitamin D intake below!

In other words, infants below the age of 1 need just 10 mcg or 400 IU of vitamin D. Between ages 1 and 70, you need 15 mcg of vitamin D daily. And after age 70, you'll need a bit more to ensure adequate vitamin D levels, at 20 daily mcg.


Do Vegans Have Low Vitamin D Levels?

Those following a plant-based diet do not tend to have more instances of vitamin D deficiency than omnivores. This is mainly because, as we'd mentioned earlier, this condition is not typically caused by diet. However, vegans who already have lower vitamin D levels may have some trouble obtaining this nutrient through diet alone. This is especially true if they hope to rely entirely on natural sources of vitamin D to obtain their daily dose.

An interesting way to get this nutrient from a natural plant source is to 'infuse' sliced button mushrooms with more vitamin D2 by exposing them to midday sunlight (for maximum UV light) for 15-120 minutes. However, the additional amount they generate will depend on various factors like weather, season, latitude, etc. So, this is not always a surefire way to ensure optimal vitamin D levels.

The easiest way for vegans to make sure they're getting enough of this fat-soluble vitamin, is to take a daily lichen-based vitamin D supplement suspended in a plant-based oil for enhanced absorption. Alternatively, you could go for a daily vegan vitamin D3 spray with an oil base.
