A vegan diet is low in some nutrients, such as B-12, that are primarily present in animal products. Vegan supplements offer a simple way for people to get enough of these nutrients. In this article, learn about the most common vegan supplements and why they are beneficial. Most vegans can benefit from taking a B-12 supplement. may be the most important supplement for vegans. It is crucial for maintaining many bodily processes. This vitamin plays a role in the formation of red blood cells, helps metabolize proteins, and even supports a healthy nervous system. Although anyone can have low vitamin B-12 levels, vegans typically have a higher risk of deficiency as there are limited vegan sources of this vitamin. It is important to note that people absorb and use vitamin B-12 differently. Even people who eat meat can have a if their body is unable to absorb the vitamin properly. The body's ability to use vitamin B-12 also declines with age. It is important for vegans to check in with their doctor from time to time to test their vitamin B-12 and iron levels. Working directly with a nutritionist or doctor can help them create a balanced diet plan. The authors of a recommend eating nori, a type of seaweed, regularly. It contains high levels of vitamin B-12 and other important nutrients for vegans, such as iron and polyunsaturated fatty acids. Another simple way to add vitamin B-12 to a vegan diet is to eat , which has a nutty, cheesy flavor. Manufacturers often fortify this inactive yeast with the vitamins that a vegan diet may be lacking. Manufacturers may fortify other foods with B-12 as well, such as tofu or other soy products, some breakfast cereals, and soy, rice, or nut milk.

The body cannot make them itself. Long chain omega-3 fatty acids, such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are nonessential, meaning that the body can make them using ALA. However, as notes, the human body has a limited capacity to convert ALA into DHA or EPA. Furthermore, vegetarians and vegans . While ALA is present in flaxseed, canola oil, and soy products, EPA and DHA are only present in fish, fish oils, and microalgae. Algae oil supplements and concentrates are the best vegan sources of EPA and DHA. Broccoli and seeds are rich in iron. is crucial for building healthy blood cells and helping them carry oxygen throughout the body. It has two different forms: heme and nonheme. Heme iron comes from animals, while nonheme iron comes from plants. Heme iron is easier for the body to absorb and use. With that said, the authors of a noted that eating a vegetarian or vegan diet high in iron-rich foods can provide the body with adequate iron. Vegan iron-rich foods include: Additionally, getting plenty of increases the intake of iron. People can request a blood test to see if they are getting and storing enough iron.

The body can make vitamin D when it gets enough sunlight. Most people can make an ample amount of vitamin D each day by spending about 15 to 20 minutes in the afternoon sun. However, this is not always possible. Wearing sunscreen, which is vital for prevention, may reduce the production of vitamin D. Many people live in areas with cold, cloudy weather and cover up their skin most of the time. Few foods contain vitamin D. Many dairy products, such as milk and yogurt, may contain added vitamin D, but these foods are not suitable for vegans. Vegan sources of vitamin D include fortified cereals and some types of mushroom.
