Convenient one capsule per week.
Vegan vitamin D from lichen.
Supports bones and immune function.

Main Highlights

✅ 1 CAPSULE PER WEEK*: Our vitamin d3 k2 depot offers the perfect dosage for easy and convenient intake: just one vegan capsule per week. Other vitamin d tablets provide critically high dosages or are very impractical to take (e.g. 1 capsule every 25 days).
🔎 VEGAN HIGH DOSE VITAMIN D: Non vegan vitamin D3 is obtained from sheep fat, a process that is very resource-intensive and unfortunately is associated with animal suffering in industrial animal husbandry. That's why we use vegan vitamin D3, which is isolated from lichen, whose structure and effect are completely identical to conventional D3.
⭐ STRONG DUO: Our high dose vitamin d and k2 vitamin K2 together play an important role in the normal maintenance of bones and teeth. They contribute to the absorption and incorporation of calcium into the bone and tooth matrix. Vitamin D is also of great importance for the normal function of muscles and the immune system.
🥼 LABORATORY TESTED: Our D3 k2 vitamin supplements are produced in Germany in accordance with HACCP quality standards. We test our k2 vitamin d capsules for microbial contamination, heavy metal residues and active ingredients. Our d3 and k2 vitamin product is GMO-free, free from synthetic additives and suitable for vegans. Per bottle: 60 capsules - a convenient one year supply.
💓 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.
