rubyni® Magnesium

Magnesium for strong bones, muscles and nerves

Do you suffer from calf cramps at night, feel constantly tired or have a nervous twitch in your eye? Then you could be missing something very basic: Magnesium.

This vital mineral supports your body in many important tasks. It helps your muscles and nerves to work properly and is a real treasure in the fight against tiredness, as it controls your energy levels. Together with calcium, magnesium also strengthens your bones and teeth.

In total, magnesium is involved in more than 600 processes in the body – this means that your metabolism cannot function smoothly without sufficient quantities of this vital substance. Many enzymes need magnesium to fulfil their task. With rubyni® Magnesium you can cover your needs naturally.

rubyni® Magnesium can help you to cover your daily requirement of this vital substance from a natural and purely plant-based source. Our vegan capsules contain high-quality organic green algae extract. This provides you with a whole complex of valuable magnesium compounds that can be easily absorbed by your body. This means that our magnesium has good bioavailability.

How much magnesium does your body need?

The German Nutrition Society (DGE) recommends an intake of 300 milligrams of magnesium per day for women and 350 milligrams for men.5 The European Union (EU) recommends a slightly higher daily dose of 375 milligrams for both sexes. This is the so-called nutrient reference value, or NRV for short. It is used as a guide in the manufacture of food supplements when it comes to the dosage of vitamins and minerals.6

The daily requirement for magnesium is higher, particularly with increased physical activity, elevated blood sugar levels and in stressful phases of life.2,4

The best supply with rubyni® Magnesium

Just two rubyni® Magnesium capsules provide you with 10 milligrams of this important mineral – and thus make an additional contribution to a balanced diet. This corresponds to 72% of the daily requirement according to NRV*.

Recommended intake: Magnesium can be taken at any time of the day, regardless of meals. We recommend that adults take one capsule of rubyni® Magnesium per day in the morning and one in the evening – with sufficient water and without chewing.

Note: The stated recommended daily intake must not be exceeded.
*Nutrient reference value (for adults according to the Food Information Regulation (FIR))

Good to know:

The body can’t function without magnesium

Magnesium is the fourth most common mineral in the human body after calcium, sodium and potassium. Many processes in your body are only possible if you have a sufficient supply of this vital substance, as more than 600 metabolic processes rely on this mineral.1

For example, cell division and the body’s own production of protein (protein synthesis) only function properly with sufficient magnesium.1,2 Magnesium is also particularly important for the electrolyte balance and therefore the transmission of stimuli in the nervous system as well as muscle contraction – and therefore also for a regular heart rhythm, normal vascular tone and normal blood pressure are also dependent on a sufficient supply of this vital substance.

In addition, magnesium not only contributes to normal energy metabolism and thus to reducing tiredness and fatigue: The mineral is also needed for normal psychological function.1 A magnesium deficiency can promote depression, for example.7 If you are under stress, your muscles tense up and you need more magnesium.4 A sufficiently high magnesium level helps against such cramped muscles. The vital substance is also needed for the production of the sleep hormone melatonin.8

Magnesium also ensures healthy bones and teeth, for which it is an important building block.9 And did you know that your defences can be impaired if your body has too little magnesium available?10

Magnesium can be found in many foods that are part of a balanced diet: For example, the mineral is found in wholemeal products, pulses, green leafy vegetables, nuts and seeds as well as fish and seafood.2

As a supplement, rubyni® Magnesium can help you meet your daily magnesium requirements from a natural source.

convinced by rubyni®

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 elderberry - it's now part of my daily routine. I am convinced of the positive effects of elderberries on my immune system, my energy balance and my fitness, especially during regeneration after periods of stress

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 convinced me as a brand. The capsules contain only extremely high-quality and natural ingredients whose effectiveness has been proven by studies and which supply the body with important nutrients. On my YouTube channel Ohlala & Solala I have published some videos about my personal rubyni® journey. There I share even more about what makes this supplement so special from my point of view.

As a biathlete, I have to be in top shape and perform to the letter. I had big problems with that in the past. My body was always weakened and I had to accept many setbacks. When I was looking for a solution to support my immune system permanently, I found elderberries as a superfood through my alternative practitioner. In the meantime, I take rubyni® with elderberries daily. The capsules are also super handy when I'm on the road in the World Cup. rubyni® is a valuable help for me in stressful competition phases and my immune system is finally back on top.

For more than 25 years, my focus has been on holistic, naturopathic medicine, with a particular interest in nutritional and biological topics. During this time, I have intensively studied current research findings (e.g. on orthomolecular medicine, epigenetics, nutrigenomics, phytotherapy). I found rubyni's philosophy of using total extracts with the complete efficacy profile of the entire fruit matrix exciting and convincing from the very beginning. That's why I was happy to take on the task of developing new products that would contain rubyni , but at the same time - in the sense of a synergism of effects - other ingredients for a specific purpose. rubyni® Visio now contains carefully coordinated ingredients that are specially formulated to meet the specific needs of the eyes. Valuable plant extracts and micronutrients have been combined to form a high-quality dietary supplement. This helps to maintain eye health and support vision.
