Vegavero

Why we love it

Supports muscle function and energy.
Contains high-quality magnesium citrate.
Vegan and additive-free.

Main Highlights

💦 MUSCLE FUNCTION AND ENERGY: Potassium and magnesium have important functions for a variety of physiological processes. They are especially important for the normal functioning of muscles, nerves and for energy metabolism. Every day, large amounts of potassium and magnesium are excreted through our sweat and must be replenished to prevent electrolyte imbalances. This is especially relevant for people who are very active.
⭐ IDEAL COMBINATION: Magnesium is tightly linked to the metabolism of potassium, which is why we combined the two minerals in one product. For our potassium and magnesium capsules we use high quality magnesium citrate and potassium citrate powders. This form is highly stable and contains significantly more elemental magnesium and potassium than other magnesium supplements. It is also characterized by a high bioavailability as the citrate mineral form is quickly absorbed by the body.
🔎 LAB TESTED: Our magnesium + potassium capsules are tasteless and thus a good alternative to magnesium and potassium tablets. We do not include anti-caking agents or other additives. In addition, we have our product analysed for various impurities. Of course, our product is suitable for vegans. Per bottle: 180 capsules. Recommended dosage: 4 capsules per day, 2 with each meal (equals 750 mg elemental potassium and 300 mg elemental magnesium).
🌿 VEGAVERO – From Nature, with Passion, For You: We respect and love nature. That's why all our supplements are vegan and free of any unnecessary artificial ingredients. We believe in the importance of guaranteeing quality and safety to our customers and therefore select our raw materials with great care. We produce our products in Germany, where they are all analyzed and certified by independent laboratories. Furthermore, we register every product with the Ministry of Health.
💓 BY YOUR SIDE: Caring for you is part of our philosophy. So, in addition to providing supplements designed for your needs, we work on unique formulas to achieve the perfect synergy of ingredients and dosages for you. If you have any queries, we are happy to advise and support you in your goals, and/or provide you with the certifications of each product and to answer all your questions.
