Dietary supplements are more in demand than ever. But not all products are created equal: The choice of the right ingredients, dosages, and formulations determines how well a supplement is actually absorbed by the body.
Vitamin D3, magnesium, or omega-3 – you often hear about their positive effects. But to benefit from these micronutrients, it's important to choose the right form and combination. How can you recognize high-quality dietary supplements?
1. Why not every nutrient source is optimally utilized
When it comes to dietary supplements, it's not just the quantity that matters, but also the quality and form of the ingredients. Here are some examples:
✅ Magnesium oxide vs. magnesium bisglycinate
Magnesium oxide is only absorbed to a small extent, while magnesium bisglycinate has high bioavailability.
✅ Vitamin D3 & K2 in oil
Vitamin D3 is fat-soluble and is better absorbed in combination with oil than in dry form.
✅ Omega-3 in triglyceride form
This form is similar to the natural fish structure and has a higher bioavailability than ethyl esters.
Example:
Vitamin D3 is an essential nutrient for the immune system and bone health. Studies show that vitamin D3 dissolved in MCT oil has better absorption than in conventional carrier substances.

2. Three important quality characteristics for food supplements
💡 Consider bioavailability
Not all forms of nutrients are created equal. Bioavailable forms ensure that the body can efficiently absorb and utilize the nutrient.
💡 Consider synergies
Nutrients often work together. For example:
Vitamin D3 and vitamin K2 together contribute to the normal maintenance of bones by regulating calcium utilization in the body.
💡 Transparency & Purity
High-quality brands rely on tested raw materials, avoid unnecessary additives, and have their products analyzed in independent laboratories.
3. Aurum Solaris – Vitamin D3 & K2 in a highly bioavailable form
Aurum Solaris by NUVÉRA contains vitamin D3 in combination with vitamin K2 (MK-7). According to the European Food Safety Authority (EFSA), this composition contributes to the normal function of the immune system and the maintenance of normal bones.
✔️ High-dose vitamin D3 with vitamin K2 (MK-7)
✔️ Dissolved in MCT oil for improved absorption
✔️ Lab-tested quality – without unnecessary additives

Conclusion
The quality of a dietary supplement depends not only on the dosage, but also on the formulation and the synergistic effects it contains. Bioavailability, transparency, and tested raw materials are crucial.
💡 Three things you should remember:
1️⃣ Bioavailability determines absorption.
2️⃣ Synergies such as D3 + K2 play an important role.
3️⃣ Laboratory-tested quality ensures transparency and safety.
