FAQs

What does it do?

Vitamin D3 + K2 supports bone strength, immune function, and cardiovascular health. Together, they help the body absorb calcium and direct it to the bones while preventing buildup in the arteries, promoting balanced mineral metabolism.*

Who is it for?

This is for anyone looking to maintain strong bones, a healthy immune system, and clear arteries. It is especially helpful if you get limited sun exposure, follow a plant-based diet, or want daily support for long-term vitality.*

How soon will I feel a difference?

Many customers begin to feel improved energy and immune support within the first week. By weeks 2 to 4, bone strength and circulation may begin improving. With daily use, D3 + K2 supports long-term calcium balance and structural health.*

Is it safe to take every day long-term?

Yes, our formulation includes bioavailable D3 (as cholecalciferol) and K2 (as MK-7) for safe and effective daily use. It’s formulated to promote calcium utilization without buildup in soft tissues. As always, consult your provider if you’re taking blood thinners or managing a condition.*

What if I’m pregnant, nursing, or on medication?

Please consult your healthcare provider before using if you are pregnant, nursing, taking medication, or have a medical condition.*

Got more questions?

Week 1

You may feel a subtle increase in energy and immune support as D3 and K2 begin optimizing calcium metabolism and overall nutrient absorption.

Week 2–4

Bone density and cardiovascular rhythm may begin to feel stronger as calcium is directed toward the right tissues and away from soft vessels.

Month 2+

With consistent use, Vitamin D3 + K2 promotes stronger bones, circulatory resilience, and long-term protection from calcium misplacement and deficiency.

Build on progress

The perfect pairings

Consider pairing D3 + K2 with Plant Calcium Complex or Omega-3 for stronger bones and circulatory support, or Collagen to strengthen connective tissue and joint integrity.*

Supporting acts

Beyond supplements

It’s called a supplement for a reason. Vitamin D3 + K2 is just one part of your daily ritual for bone strength, heart health, and calcium absorption. It’s here to add to what truly matters — what you eat, how you move, and the intentional choices you make each day.

  • Eat fat-soluble nutrients

    Pair your supplement with healthy fat sources like eggs, avocado, salmon, or olive oil. These support the absorption of both D3 and K2, reinforcing their benefits for bone density, mood, and immunity.

  • Move for bone strength

    Weight-bearing exercises like walking, resistance training, or hiking help stimulate bone remodeling and density. These forms of movement work alongside D3 and K2 to support skeletal strength and cardiovascular balance.

  • Get consistent sunlight

    Safe sun exposure, especially in the morning, helps regulate your circadian rhythm and naturally supports vitamin D synthesis. These habits reinforce your supplement and help regulate mood, sleep, and immune function.

Still early but feeling good

Only a couple weeks in, but I feel good. Shipping felt a bit slow but that’s on me for ordering right before a long weekend. Love the quality of the packaging.

Dear Kevin, thank you for the feedback. We are so glad to hear it is off to a good start and that the quality stands out. We are currently shipping from a single warehouse in Los Angeles, which can add a bit of time depending on your location, especially around holidays. We appreciate your patience and are happy to have you with us. Best regards, Arken.
