VitaDK plus: Vitamin D3 with K2, Magnesium, Zinc, and Boron – Your Sun Power Complex
Imagine you’re soaking up the sun. Your skin produces Vitamin D3 – the sunshine vitamin. But with our modern lifestyle, it’s almost impossible to produce enough of it: We spend most of our time indoors, behind windows, in cars. Even in summer, sun exposure is often insufficient.
For Vitamin D to fully work, your body needs more: Magnesium activates it. Vitamin K2 directs calcium specifically to the bones. Zinc ensures that the receptors in your cells function. Boron keeps everything available longer.
This is not just any combination. This is how nature intends it – an interplay where each nutrient strengthens the other.
VitaDK plus combines all these natural partners in a well-thought-out complex formula. For your bones, muscles, and immune system.* Complete like sunlight working from within.
When Your Sun Power Complex Supports You:
- Your daily life mostly takes place indoors: Your skin rarely sees real sunlight
- The dark months drain your energy: You feel tired, more susceptible, less stable
- You already take Vitamin D and want to ensure your body can fully utilize it
- You don’t want to deal with five separate doses and are looking for a complete solution that simply works
Why We Developed VitaDK plus:
In our therapeutic work, we’ve seen it time and again: People supplement Vitamin D – often for years – and still hardly notice a change. The reason? They lack the co-factors that activate and make Vitamin D usable. At the same time, many were tired of juggling between five different doses.
We wanted a solution that truly makes sense. A complex formula that unites all the important nutrient partners – in bioactive forms, precisely dosed, and synergistically coordinated.
VitaDK plus is the result of this conviction. Thoughtfully designed and holistically developed with years of practical experience. Made in Germany. And with the claim that your body deserves complete solutions.
We are often asked what sets our products apart from conventional supplements. The answer is quite simple: it’s the quality of the ingredients and, of course, the formulation! To allow you to check for yourself, we have compiled the most important quality criteria here.
What you should consider when buying a vitamin D product:
Are all co-factors included? (K2, magnesium, zinc, boron, not just D3 alone)
Are the nutrients in bioactive form? (Cholecalciferol instead of D2, MK-7 all-trans instead of synthetic K, citrates instead of carbonates)
Is it free from additives and allergens?o maltodextrin,o stearates, flavors, or fillers – and particularly free from lactose, gluten, soy, sugar, purine, iodine, milk, egg, yeast.
Is the dosage therapeutically well-considered? (Not just minimal care, but complete support)
Is the origin transparent? (Made in Germany, certified production, GMO-free)

Your body is a masterpiece and works best when everything fits together.
Our complex formulations think the same way: Instead of isolating individual nutrients, we combine them with their natural partners – just as nature intended. Each nutrient has its own role, but only in synergy do they unleash their full power. For your body, which deserves complete solutions.
How the nutrients in VitaDK plus complement each other
VitaDK plus is more than the sum of its parts. Each nutrient has its own task, but only in synergy do they unleash their full power. Here you can see how the synergy team works:
- Vitamin D3 (Cholecalciferol): The Director
5,600 I.U. (140 µg) per daily dose
Vitamin D3 is the central actor: It promotes calcium absorption, supports your bones, muscles, teeth, and immune system.* But without its partners, it cannot be fully activated and utilized. - Vitamin K2 (Menaquinone MK-7, all-trans): The Conductor
75 µg per daily dose
While Vitamin D ensures calcium is absorbed, K2 directs it precisely where it’s needed: into your bones and teeth – not into your blood vessels.* The all-trans form is the most bioactive and stable variant. - Magnesium (as citrate): The Activator
150 mg per daily dose
Magnesium is the switch that turns Vitamin D on in the first place. It converts D3 into its biologically active form while also supporting your muscles, nerves, and energy production.* Without magnesium, Vitamin D remains inactive. - Zinc (as citrate): The Doorkeeper
5 mg per daily dose
Zinc ensures that the Vitamin D receptors (VDRs) in your cells function properly. Only then can Vitamin D dock and exert its effect. At the same time, zinc protects your cells from oxidative stress and supports skin, hair, nails, and the immune system.* - Boron (as sodium tetraborate): The Enhancer
5 mg per daily dose
Boron is the silent hero – often overlooked – but indispensable: It improves magnesium absorption, increases serum Vitamin D levels, and extends its availability. Additionally, it is involved in numerous metabolic processes – from bones to hormones to carbohydrate metabolism.
This is synergy: Each nutrient makes the other stronger. Together they form the complete team your body needs.

Product Background
Vitamin D3 + K2 with Magnesium, Zinc, and Boron: Why Your Body Needs More Than Just Vitamin D
Do you often feel tired, lethargic, or more susceptible to colds in the winter? This could be due to your vitamin D levels. Vitamin D3 is involved in over 300 metabolic processes—from strengthening your immune system and maintaining your bones to supporting your muscles and nerves. However, vitamin D alone is not enough to work optimally.
The Problem: Modern Lifestyle and Vitamin D Deficiency
Vitamin D is the only vitamin that your body can produce itself—but only with sufficient sunlight on the skin. Due to our modern lifestyle with many hours indoors, long workdays in the office, and the use of sunscreen, natural production is often not possible. Especially in the winter months from October to March, sunlight in Germany is too weak to produce enough vitamin D. It is also difficult to meet the requirement through diet—vitamin D is only found in significant amounts in a few foods like fatty fish, eggs, and mushrooms.
No wonder many people today have low vitamin D levels. Studies show that about 60% of the population in Germany is not adequately supplied with vitamin D. The result: fatigue, weakened immune system, muscle and bone complaints.
The Solution: Synergy Instead of Single Substance
VitaDK plus was developed by dr.reinwald vital as a well-thought-out complex formula that combines vitamin D3 (cholecalciferol) with its most important co-factors: vitamin K2 (MK-7, all-trans), magnesium, zinc, and boron. Why is this combination so important?
Vitamin K2 ensures that the calcium absorbed through vitamin D is incorporated into the bones and teeth—not the blood vessels. Magnesium activates vitamin D into its biologically active form and simultaneously supports your muscles, nerves, and energy production. Zinc enables the function of vitamin D receptors in almost every body cell and strengthens your immune system. Boron improves the absorption of magnesium and prolongs the availability of vitamin D in the body.
What Makes VitaDK plus Special:
- Substantial Amount: 5,600 IU of vitamin D3 per daily dose (2 capsules)—optimal for maintaining a healthy vitamin D level
- Bioactive Forms: Cholecalciferol (D3), menaquinone MK-7 all-trans (K2), citrates (magnesium, zinc) for maximum bioavailability
- Synergy Complex: All co-factors in one product, no need for individual supplements
- Premium Quality: Made in Germany, without additives, non-GMO
- Orthomolecular Approach: Developed by therapists for holistic care
Consumption Recommendation for Optimal Absorption
For optimal absorption, it is recommended to take VitaDK plus with a meal containing some fat, as vitamins D and K are fat-soluble. A handful of nuts, some avocado, or a tablespoon of olive oil is sufficient to support absorption.
VitaDK plus combines the most important micronutrients for the immune system, bones, muscles, and energy in a natural, high-quality complex formula that your body can optimally utilize.
FAQ & Frequently Asked Questions about VitaDK plus and Vitamin D
Even those who live in sunny regions or spend a lot of time outdoors can have a low vitamin D level. The body’s own production depends not only on sunlight but also on skin type, age, season, and lifestyle. In Germany, sunlight from October to March is too weak for sufficient vitamin D production. Additionally, sunscreen (important for skin health!) prevents vitamin D formation. A targeted supplement with VitaDK plus can help meet the daily requirement year-round.
Vitamin D3 promotes calcium absorption. Vitamin K2 directs this calcium specifically into bones and teeth – not into blood vessels. Magnesium activates vitamin D into its biologically active form. Together with zinc (opens the vitamin D receptors) and boron (extends the availability of vitamin D), an optimal synergy for bones, muscles, and the immune system is created – exactly what VitaDK plus offers.
VitaDK plus contains 5,600 IU (140 µg) of Vitamin D3 per daily dose (2 capsules). This corresponds to a therapeutic dosage that aligns with the recommendations of leading vitamin D experts and is designed to maintain or optimize a healthy vitamin D level—especially during the sun-poor months.
VitaDK plus is designed for daily consumption and provides a safe, balanced combination of Vitamin D3, K2, Magnesium, Zinc, and Boron. An overdose is only possible with consistently extremely high amounts (>10,000 IU daily over months) and is hardly realistic at the recommended dosage of 2 capsules daily. The included co-factors also support the safe utilization of Vitamin D in the body.
VitaDK plus is ideal for those who:
- get little sunlight (office work, indoor lifestyle)
- need additional support in the winter months (October to March)
- have an increased need (e.g., from age 40, during pregnancy/breastfeeding, with athletic stress)
- want to specifically support their bones, muscles, and immune system
- value quality: bioactive forms, vegetarian, without additives, Made in Germany
VitaDK plus contains no animal additives. However, the vitamin D3 is derived from lanolin (wool wax) and is therefore not completely vegan, but suitable for vegetarians. The capsule shell is made of plant-based cellulose.
Take 2 capsules daily with a meal containing some fat (e.g.,
uts, avocado, olive oil) – ideally at breakfast or lunch. Vitamin D3 and K2 are fat-soluble and are optimally absorbed this way. Many take VitaDK plus in the morning, as vitamin D can provide energy – but taking it at noon or in the evening is also possible.
