Amen's Vitamin D, K2 & Zinc combines three nutrients that work in concert to support bone density, immune function, and calcium metabolism. This formulation pairs vitamin D3 with vitamin K2, a form clinically noted for directing calcium toward bones rather than soft tissue, alongside zinc for additional immune and cellular support. It's well-suited for adults looking to address multiple foundational nutrient needs in a single daily capsule.
Why It's Worth Considering: The D3/K2 pairing is a thoughtful combination, as K2 may help optimize how the body utilizes the calcium that vitamin D promotes for absorption, making this a more complete approach than vitamin D alone.

More category questions
How much vitamin D3 should I take daily?
Most functional medicine practitioners recommend 5,000 IU daily for adults with normal BMI, and up to 10,000 IU for those with obesity or severe deficiency. The Endocrine Society recommends maintaining serum 25(OH)D levels between 40-60 ng/mL. Test your levels every 3-6 months.
Is vitamin D3 better than D2?
Yes. D3 (cholecalciferol) is 87% more effective at raising and maintaining serum vitamin D levels compared to D2 (ergocalciferol). D3 also has a longer half-life. D2 is only preferred by strict vegans who cannot use lanolin-sourced D3 — lichen-based D3 is the vegan alternative.
Should I take vitamin D3 with vitamin K2?
Yes, especially at doses above 2,000 IU. Vitamin D3 increases calcium absorption from food. Without K2, that calcium can deposit in arteries instead of bones. K2 (MK-7 form) activates osteocalcin (puts calcium in bones) and matrix GLA protein (keeps calcium out of arteries).
Can I take too much vitamin D?
Toxicity is rare below 10,000 IU/day in healthy adults but possible with chronic high-dose use without monitoring. Symptoms of excess include hypercalcemia (nausea, kidney stones, confusion). Always pair high-dose D3 with K2 and test 25(OH)D levels every 3-6 months.
When is the best time to take vitamin D3?
Take with your largest meal containing fat — D3 is fat-soluble and absorption increases 30-50% when taken with dietary fat. Morning or afternoon is preferred over evening, as some studies suggest late-night D3 may interfere with melatonin production.
How long does it take for vitamin D levels to increase?
Serum 25(OH)D typically rises within 1-2 weeks of supplementation. Reaching optimal range (50-80 ng/mL) takes 2-3 months at 5,000 IU/day from a deficient baseline. Higher loading doses (10,000 IU for 8 weeks then maintenance) can accelerate this.
