How much magnesium does your body need?
Magnesium is found in many foods that are part of a balanced diet: For example, this mineral is found in whole-grain products, legumes, green leafy vegetables, nuts, and seeds, as well as in fish and seafood.2
The German Nutrition Society (DGE) recommends a daily intake of 300 mg of magnesium for women and 350 mg for men.2 The European Union (EU) recommends a slightly higher daily dose of 375 mg for both genders. This is known as the Nutrient Reference Value, or NRV for short. It serves as a guideline in the manufacture of dietary supplements when it comes to the dosage of vitamins and minerals.3,4
Individual magnesium needs can vary depending on diet and lifestyle.

Magnesium – a mineral essential for numerous bodily functions
Magnesium is one of the most abundant minerals in the human body and plays a role in various metabolic processes. For example, magnesium helps maintain electrolyte balance.1,5 The term “electrolytes” refers to various minerals that are dissolved in the blood, among other places. Various processes in your body depend on the electrolytes being in balance.6
Magnesium also helps reduce tiredness and fatigue.1 However, you probably associate this nutrient more with your muscles. And rightly so: Your muscles work by contracting and relaxing. Magnesium plays a role in regulating these movements and supports normal muscle function.1,7,8,9
What does magnesium have to do with your bones?
Did you know that a large portion of the magnesium in your body is found in your bones? They contain more than 50% of this mineral and serve as a magnesium store. Bones are living tissue that is constantly being renewed throughout your life. Magnesium helps maintain normal bones.1,7,9,10

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.
