rubyni® Selenium from Organic Sunflower Seed Extract
For our vegan rubyni selenium capsules, we use organic sunflower seed extract, a plant-based source that naturally contains selenium.
Selenium plays a role in various processes in your body. For example, it contributes to normal thyroid function and helps maintain normal hair and nails.1

How much selenium does your body need?
Selenium is a trace element. This means your body needs only small amounts of it—in the microgram range—but these are essential for the body and must be supplied regularly. But how much is we’re talking about?
The German Nutrition Society (DGE) provides certain estimated values for selenium. This means it assumes that this amount is sufficientto meet the human body’sneeds for this trace element. According to theDGE2 ,
- Women and pregnant women: 60 µg of selenium daily
- Men: 70 µg of selenium per day
- Breastfeeding women: 75 µg of selenium daily
This corresponds to a daily intake of about 1 µg of selenium per kg of body weight.3
The European Union (EU) recommends the same amount of selenium for both genders: 55 µg per day. The so-called Nutrient Reference Value (NRV for short) serves as a guideline in the manufacture of dietary supplements when it comes to the dosage of vitamins and minerals.4
Individual selenium requirements may vary depending on diet and lifestyle. Overall, according to the Joint Expert Committee on the Classification of Substances, no more than 300 µg of selenium should be consumed per day.5
Here’s what’s in our capsules
One Rubyni Selen capsule contains 11 mg of sunflower seed extract and provides 55 µg of the trace element. This amount corresponds to 100% of the daily selenium requirement based on the Nutrient Reference Value (NRV*).
Note: Food supplements should not be used as a substitute for a balanced and varied diet or to replace a healthy lifestyle.

rubyni® Selenium at a Glance
rubyni Selen is a dietary supplement that contains sunflower seed extract as a natural source of selenium. As a result, the trace element in our capsules is present in combination with plant-based ingredients. The sunflowers (Helianthus annuus) are organically grown.
The extraction process is gentle and uses ingredients of natural origin—such as red cabbage water, lime juice, and coconut vinegar.
The selenium content is standardized during the processing of the extract to ensure that you always receive consistent quality.
We have added organic carrot powder from Germany to our product. It is raw food quality.
Good to know:
Selenium—a trace element essential for numerous bodily functions
The amount of selenium in the human body is relatively small, ranging from just 5 to 15 mg.6 Nevertheless, this trace element plays a role in various bodily processes. For example, selenium contributes to the normal function of the thyroid gland.1 This small, butterfly-shaped gland in your neck produces hormones that are involved in various bodily functions.7
In addition, selenium helps maintain normal hair and nails, supports the normal function of the immune system, and contributes to normal sperm production.1
So-called oxidative stress is caused by free radicals. These highly reactive molecules can form in the body when it is exposed to certain external factors—such as UV radiation or pollutants. Free radicals can damage cells in the body. Selenium helps protect the body’s cells from oxidative stress.1,8
Germany: How much selenium is in our soil?
Selenium is found in both animal and plant-based foods. Cabbage, onions, asparagus, legumes, and mushrooms may contain selenium.9,10 However, the amount of selenium in plant-based foods depends on the selenium content of the soil. In Europe—including Germany—many soils are considered to be relatively low in selenium. As a result, plant-based foods grown in Europe often contain relatively small amounts of selenium. Grain products from other regions, such as the United States, sometimes have higher selenium levels.9,10,11
Selenium intake can therefore vary in plant-based diets.
In Europe, selenium may be added to animal feed to meet the animals’ needs. For this reason, animal products such as meat and eggs are generally good sources of selenium.11
What role does selenium play in the body (Health Claims)?
The trace element selenium plays a role in various bodily functions.
- contributes to normal thyroid function
- contributes to the maintenance of normal hair
- contributes to the maintenance of normal nails
- contributes to the normal function of the immune system
- contributes to the protection of cells from oxidative stress
- contributes to normal sperm formation
What makes rubyni Selen so special?
rubyni Selen provides you with plant-based selenium from a natural source in the form of an extract. We extract this trace element from organically grown sunflower seeds (Helianthus annuus). The gentle extraction process uses ingredients of natural origin, such as red cabbage water, lime juice, and coconut vinegar. Our product is supplemented with organic carrot powder grown in Germany.
Is Rubyni Selen vegan, lactose-free, and gluten-free?
Yes, rubyni Selen consists of 100% vegan ingredients in a vegetable capsule (made from hydroxypropyl methylcellulose): The selenium comes from a sunflower seed extract (Helianthus annuus). The product is supplemented with organic carrot powder. All ingredients are vegan, lactose-free, and gluten-free.
How many Rubyni Selen capsules should I take each day?
For adults, the recommended daily intake is one rubyni Selen capsule. Take one capsule with plenty of water, without chewing. Each capsule provides 11 mg of sunflower seed extract, which contains 55 µg of selenium. This corresponds to 100% of the daily value according to the NRV.
How does selenium support the body?
Selenium plays a role in many bodily processes: It contributes to the normal functioning of the thyroid gland and the immune system, as well as to normal sperm production. In addition, this trace element helps maintain healthy hair and nails. Last but not least, selenium helps protect the cells in your body from oxidative stress.
How can I meet my selenium needs?
Selenium is a trace element that you must consume regularly through your diet, since your body cannot produce it on its own. In Europe, selenium levels in the soil are often relatively low, which is why selenium levels in plant-based foods can vary. Animal products such as meat and eggs can be significant sources of selenium, as the trace element is permitted to be added to animal feed. Dietary supplements can serve as a complement to a balanced and varied diet.

EXPERIENCES THAT BUILD TRUST
Tobias Angerer
Cross-country skier
As a former professional athlete and health-conscious person, my physical performance and well-being are extremely important to me. That's why I take rubyni® with elderberries - it's now part of my daily routine. I am convinced of the positive effects of elderberries on my immune system, my energy levels and my fitness, especially during regeneration after periods of exertion.
Andrea Sokol
Phytotherapist | Nutrition and health consultant
I work as a nutrition and health consultant and am a trained phytotherapist. Transparency, sustainability and quality are very important to me. And I have to say that rubyni® has completely won me over as a brand. The capsules contain only extremely high-quality and natural ingredients whose effectiveness has been proven by studies and which provide the body with important nutrients. I have published several videos about my personal rubyni® journey on my YouTube channel Ohlala & Solala. There I tell you even more about what makes this dietary supplement so special from my point of view.
Hanna Kebinger
Biathlete
As a biathlete, I have to be fit and able to perform at the drop of a hat. I had big problems with that in the past. My body was repeatedly weakened and I had to put up with many setbacks. When I was looking for a solution to support my immune system in the long term, my naturopath introduced me to elderberries as a superfood, among other things. I now take rubyni® with elderberries every day. The capsules are also super handy when I'm on the World Cup circuit. Rubyni® is a valuable aid for me during stressful competition phases and my immune system is finally back on top form.
