The important trace element selenium
As a component of important enzymes, selenium is involved in numerous metabolic processes. For example, it is found in the antioxidant enzyme glutathione peroxidase, which helps combat oxidative stress.
Selenium also plays a key role in the production of thyroid hormones. The enzymes known as deiodinases, which convert inactive T4 into active T3, depend on a sufficient supply of selenium.
According to officially recognized health claims, selenium contributes:
- to maintain normal hair
- to maintain normal nails
- to normal thyroid function
- to protect cells from oxidative stress
- to normal function of the immune system
- to normal sperm production
Edubilys Selenium Capsules contain three different forms of selenium: selenium yeast, sodium selenite and L-selenomethionine and 45 μg of selenium per capsule.
Why selenium deficiency is becoming more common
Natural sources of selenium include fish, meat, eggs, nuts, and grains. However, soils in Europe are relatively poor in selenium, which explains the often inadequate selenium supply in many European countries (1).
The concentration of selenium in soil varies by region and is influenced by factors such as rainfall, soil pH, and agricultural practices. Intensive agriculture and the use of fertilizers without selenium further decrease the selenium content in soils. Especially in parts of Europe and China, soils are particularly poor in this trace element, which directly impacts selenium intake through food.

Three different forms of selenium for maximum effectiveness
To ensure optimal supply, edubily relies on a combination of three different forms of selenium:
Selenium yeast
This organic selenium source is produced by cultivating yeast in a selenium-containing nutrient medium. The main component is selenomethionine, supplemented by other organic selenium compounds such as methylselenocysteine.
Sodium selenite
As an inorganic selenium compound, sodium selenite is rapidly absorbed by the body but also rapidly excreted. It is particularly suitable for short-term selenium supplementation, but has only a limited effect on blood levels.
L-selenomethionine
This organic form of selenium occurs naturally in plant and animal foods. Because it is incorporated into the body's own proteins instead of methionine, it has a long-term storage effect.In addition, L-selenomethionine is particularly suitable for raising plasma selenium levels (2).

Proven quality from edubily
The edubily PURE Selenium capsules are a high-quality and reliable way to supplement the body with this essential trace element. Thanks to the excellent bioavailability of selenomethionine, effective absorption is guaranteed.
Like all products in the PURE series, edubily's selenium contains no unnecessary additives. It only contains Rice flour as a filler, as it is necessary for production reasons.
Frequently Asked Questions & Answers from Edubily
What does the body need selenium for?
Selenium is essential for the immune system, protects cells from oxidative stress and supports healthy hair, nails and thyroid function.
Is it possible to get enough selenium through food?
In Germany, selenium is one of the nutrients most frequently deficient. The reason for this is the low selenium content of the soil, which means that the foods grown there often contain very little selenium. To ensure an adequate supply of this essential trace element, it is important to include selenium-rich foods, such as Brazil nuts from the Brazilian rainforest, in your diet and consume them regularly.
Do I possibly have a selenium deficiency?
Signs of a deficiency can include brittle nails, hair loss, or increased susceptibility to infections. Inadequate selenium intake affects many people in Europe.
How long does it take for selenium to work in the body?
This depends on the individual's health status and diet. Typically, the positive effects of selenium, such as strengthening the immune system and protecting against oxidative stress, become noticeable after a few weeks of continuous intake.
Should you take selenium daily?
A daily intake of selenium is recommended to ensure a stable level of this essential trace element in the body. Since the body cannot produce selenium itself, a continuous intake through food or supplements is necessary. Regular intake helps prevent deficiency and maximizes the numerous beneficial effects of selenium.
Why do the capsules contain 3 forms of selenium?
The combination of selenium yeast, selenomethionine and sodium selenite ensures optimal bioavailability and supports the body in many ways.
How much selenium does one capsule contain?
One capsule contains 45 µg selenium.
What should not be taken together with selenium?
When taking selenium, it should be noted that high doses of vitamin C can impair the absorption of sodium selenite in the body. In contrast, the absorption of selenomethionine remains unaffected, as the selenium is tightly bound to the amino acid methionine. To ensure the best possible effect of both nutrients, it is recommended to take them at different times.
Are there any side effects?
In appropriate amounts, selenium is well tolerated and harmless for most people.However, excessive intake can cause side effects such as nausea, diarrhea, hair loss, brittle nails, and in extreme cases, even neurological impairment. Therefore, it is important to adhere to the recommended daily intake and consult a doctor or nutritionist if unsure.
Does the product contain additives?
No, it is free of any additional substances and consists only of selenium and rice flour as a filler.
Is the product vegan?
Yes, both the selenium contained and the HPMC capsule shell are vegan.
