The selenium is a trace mineral that is often overlooked in plant-based diets. Yet it plays an essential role in thyroid function, immune health, and protection against oxidative stress.
In a vegan diet, meeting your selenium needs can sometimes seem complicated because selenium levels vary significantly between foods. Selenium content can vary depending on brands, agricultural soils, and production methods. These estimates are based on the data used in the Veg’Up app and extracted from the CIQUAL database.
Daily recommendations are 70 µg/day. (Source: ANSES)

Common selenium mistakes
Relying only on Brazil nuts
Brazil nuts are often presented as the miracle solution. The problem: their selenium content varies greatly depending on their geographic origin. One nut may contain 50 µg, while another may contain more than 90 µg. Eating too many regularly can lead to excessive intake.
👉 Ideally: stick to 1–2 nuts occasionally and diversify your sources.
Ignoring other food sources
Many people only think about Brazil nuts, while many everyday foods also contain selenium:
- legumes
- whole grains
- seeds
- tofu
- mushrooms
A varied diet often makes it much easier to meet your needs.
Ignoring selenium’s role in thyroid health
Selenium supports proper thyroid function, especially alongside iodine. For vegans and vegetarians, it can be useful to monitor both selenium and iodine intake.
Should you take a selenium supplement?
In most cases: no. A well-balanced vegan diet is usually enough. A supplement may be worth discussing with a healthcare professional if you have:
- confirmed deficiency
- specific thyroid issues
- a very restrictive diet
- specific medical recommendations
Avoid self-supplementation: too much selenium can also be harmful.
How do you know if you’re getting enough selenium?
The issue with selenium is that very few people actually know how much they consume each day. Many people assume they eat a balanced diet… without having visibility over their actual intake. That’s exactly why the Veg’Up Nutrition app helps you easily track your vitamin and mineral intake, including selenium, to make sure your diet truly meets your needs.
