About this supplement
Calcium Metabolism and the D3-K2 Relationship
Bone is a living tissue continuously broken down and rebuilt throughout life, with calcium as its primary structural mineral. Vitamin D plays a central role in calcium metabolism, supporting its absorption from food in the intestine and helping regulate circulating calcium levels. Vitamin D status varies considerably across populations, particularly in northern latitudes where sunlight-driven Vitamin D synthesis in the skin is limited for extended periods of the year. Vitamin K2 in the MK-7 form is involved in the activation of calcium-regulating proteins including osteocalcin, produced by bone-forming cells, and Matrix Gla Protein, both of which require Vitamin K2 for activation. The interaction between D3 and K2 is therefore relevant not only to how much calcium is absorbed but to how it is subsequently distributed in the body.
Vegan D3 From Lichen: A Rare and Considered Choice
Almost all Vitamin D3 supplements use cholecalciferol derived from lanolin, a byproduct of sheep's wool. D3 + K2 uses cholecalciferol sourced from Cladonia rangiferina, a lichen and a plant-based source with equivalent bioavailability to standard D3. For anyone vegan, vegetarian or attentive to ingredient sourcing, it is a meaningful distinction and one that most D3 products on the market do not offer.
MenaQ7®: The Gold Standard for Vitamin K2
Not all Vitamin K2 is the same. D3 + K2 uses MenaQ7®, a patented K2 MK-7 ingredient developed by NattoPharma and the most clinically studied Vitamin K2 available. At 750µg per serving (1,000% NRV), it is included at a dose that reflects the seriousness of the formula, not the minimum needed to put K2 on a label. MenaQ7® is the reference standard used by serious supplement formulators worldwide.
100µg D3 at 2,000% NRV: A High-Strength Daily Dose
Each serving delivers 100µg of Vitamin D3, equivalent to 4,000 IU. Vitamin D insufficiency is among the most commonly identified nutritional findings across European populations, and a high-strength daily dose ensures meaningful intake regardless of sun exposure or dietary sources.
Advanced Microgranule Technology
D3 + K2 uses coated microgranules engineered for ingredient stability, no capsules and no tablets. Take the granules directly with water, or mix into yoghurt, juice, a smoothie or breakfast food. Do not mix with hot food or drinks.
Frequently asked questions
Is a scoop included?
Yes. One level scoop is your full daily serving.
How long does one container last?
30 servings, a full month supply at the recommended daily dose of one scoop.
Why take D3 and K2 together?
Vitamin D3 supports calcium absorption from food. Vitamin K2 MK-7 is involved in the activation of proteins that direct where calcium is deposited in the body. Together they address both sides of the calcium metabolism process. Taking them in a single daily scoop is more practical than managing two separate products.
Why vegan D3 from lichen?
Most D3 supplements use cholecalciferol derived from lanolin, a byproduct of sheep's wool. D3 + K2 uses cholecalciferol from Cladonia rangiferina, a lichen, with equivalent bioavailability. For anyone vegan, vegetarian or paying attention to ingredient sourcing, the distinction is meaningful.
What is MenaQ7® and why does it matter?
MenaQ7® is a patented Vitamin K2 MK-7 ingredient developed by NattoPharma, the most clinically studied K2 ingredient available. It is the form used in most serious K2 research and the reference standard for premium K2 supplementation. At 750µg per serving, it is included at a meaningful dose.
Can I take D3 + K2 alongside other GetTested supplements?
Do not combine with other supplements containing high levels of Vitamin D or Vitamin K. If you are taking blood thinners or anticoagulant medication, consult a healthcare professional before use as Vitamin K affects blood clotting.
Who should not take D3 + K2?
Not recommended for children, during pregnancy or breastfeeding unless advised by a healthcare professional. Consult a healthcare professional before use if you are taking anticoagulant or blood-thinning medication, other medication, or have a medical condition. Do not exceed the recommended daily dose.
How should I store it?
In the original sealed packaging, in a dry place away from light at +5 to +25°C.
