Key Facts

  • A liquid combination of vitamins D3 and K2 that work together to optimize how your body uses calcium
  • Supports bone density, cardiovascular health, and immune function through calcium regulation
  • Addresses the gap left by vitamin D alone: D3 helps you absorb calcium, while K2 directs it to bones instead of soft tissues and arteries
  • Liquid form enhances absorption compared to many tablet alternatives

Ingredients

Vitamin D3 (25 mcg / 1,000 IU), vitamin K2 as menatetrenone / MK-4 (200 mcg), medium chain triglycerides, mixed tocopherols.

Why We Chose This

Most people have suboptimal vitamin D levels, but taking D3 alone tells only half the story. Without K2, the calcium your body absorbs can deposit in arteries and soft tissues rather than bones — the opposite of what you want. This formulation pairs D3 with K2 in a research-backed ratio, delivered in liquid form for better bioavailability. The combination addresses a real physiological need: calcium trafficking. Clean ingredients and no unnecessary additives make this a straightforward way to support bone strength and cardiovascular health without the guesswork.

Frequently Asked Questions About Vitamin D + K2 Liquid

What is the supporting research for the benefits of vitamin D + K2 liquid?
  • Vitamin D promotes calcium absorption, while vitamin K appears to direct calcium to bone. (mechanistic review)
  • Combined D and K supplementation is associated with greater bone mineral density improvements. (clinical data review)
  • D3 and K2 supplementation is associated with significantly improved lumbar spine density. (randomized trial)
How do I take vitamin D + K2 liquid?

Take 2 drops one to three times daily, inverting the bottle to dispense individual drops.

You can add drops directly to food or mix into beverages, ideally with a meal for optimal absorption. Do not refrigerate.

Can I take vitamin D + K2 liquid with other supplements or medications?

Vitamin D + K2 liquid is generally safe to take with other supplements and medications at recommended dosages, though certain medications like statins, thiazides, warfarin, and antibiotics may interact with these vitamins. Consult your healthcare provider before combining this supplement with any medications or other supplements to ensure compatibility.

Who might benefit from taking vitamin D + K2 liquid?

Anyone with sub-optimal vitamin D levels—which includes most people—benefits from this combination for stronger bones and cardiovascular protection. Those concerned about calcium distribution and arterial health particularly gain from vitamin K2's role in directing calcium where it belongs.

How long does it typically take to notice effects of vitamin D + K2 liquid?

Most people notice improvements in vitamin D levels within a few weeks of consistent supplementation, though full benefits typically emerge over 2 to 3 months as your body reaches optimal levels. Individual timelines vary based on how deficient you were to start, so patience and consistency matter more than immediate results.
