Mobility and Vitality in Everyday Life

The terms “vitality” and “mobility” are often associated with various aspects of physical and mental well-being. For many people, they are essential for maintaining an active lifestyle even as they age.

There are various factors that can positively influence your vitality and mobility. These include regular exercise and a varied diet. In certain life situations, dietary supplements can be a practical addition to a balanced diet.

What exactly are enzymes?

 

Enzymes are essential for countless metabolic processes in the human body: They ensure that certain biochemical reactions can proceed quickly and efficiently. These specialized proteins lower the so-called activation energy required for a specific reaction. Each enzyme is specialized for a specific substance, known as the substrate.1,3

One group of enzymes is known as proteases: They can break down other proteins and areinvolved, among other things, in the degradation and remodeling of proteins.⁴ The two enzymes bromelain and papain, found in pineapple and papaya, also belong to the group of protein-digesting enzymes.

 

Cofactors: Partners of Many Enzymes

Many enzymes are true team players: To become activated and perform their function, they require what are known as cofactors. These can be various substances, such as vitamins or minerals. For example, the trace element zinc serves as a cofactor for numerous enzymes.5

Good to know:

Zinc, biotin, and vitamin B6 for numerous bodily functions

 

Vitamins and minerals perform various functions in the human body. Some of them are involved in the same processes: For example, both zinc and vitamin B6 contribute to the normal functioning of the immune system. Biotin and vitamin B6, in turn, contribute to normal energy metabolism, normal nervous system function, and normal psychological function.2

In addition, each of the three micronutrients plays a role in other processes. Vitamin B6 helps reduce tiredness and fatigue. Zinc, in turn, supports normal cognitive function and helps protect cells from oxidative stress. Oxidative stress is triggered by highly reactive molecules—known as free radicals—and can damage cells.6

Frankincense and Turmeric in a Combo Pack

Frankincense (Boswellia serrata) and turmeric (Curcuma longa)⁷ have traditionally been valued in many cultures. Frankincense is the dried resin of trees of the genus Boswellia (Balsam family).⁸

Turmeric, or yellow root, contains curcuminoids, particularly curcumin. This plant compound is known to many people as the yellow-coloring component of the spice blend curry. Turmeric is featured in various dietary approaches—and, like frankincense, is a popular botanical ingredient in modern dietary supplements.9

What nutrients are found in wild blueberries?

Wild blueberries (Vaccinium myrtillus) are characterized by a high content of phytochemicals—specifically, polyphenols and anthocyanins. These compounds are responsible, among other things, for the intense color of these small fruits.10 With our highly concentrated berry extract—which is extracted using purely mechanical methods and without the use of solvents—these characteristic compounds are available to you year-round.

For rubyni Enzym Plus, we use only the finest brand-name ingredients:

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.

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.

Expert in nutritional medicine

For more than 25 years, my focus has been on holistic, naturopathic medicine, with a particular interest in nutritional medicine and biological topics. During this time, I have studied current research findings (e.g. on orthomolecular medicine, epigenetics, nutrigenomics, phytotherapy) in depth. From the outset, I found rubyni's philosophy of using whole fruit extracts with the complete effect profile of the entire fruit matrix exciting and convincing. That is why I was happy to take on the task of developing new products that would contain rubyni but also, in the spirit of synergistic effects, other ingredients for a specific purpose.
