Why Vitamin D3 + K2?

Vitamin D3 and K2 are a team: D3 helps your body absorb calcium, and K2 (as MK-7, the long-acting form) helps direct that calcium to your bones — where you want it — rather than your arteries, where you don't.*

Together they support bone strength, immune function, and cardiovascular health — especially important as sunlight exposure and absorption decline with age.*

Ingredients

Per 2-softgel serving: Vitamin D3 (250 mcg / 10,000 IU) and Vitamin K2 as Menaquinone-7 (200 mcg).

No artificial dyes or preservatives. Made in FDA-registered, GMP-certified U.S. facilities.

Vitamin D3 + K2 supplement facts
How To Take

Take 2 softgels daily with a meal containing some fat — both D3 and K2 are fat-soluble vitamins, so food is essential for absorption.

This is a robust daily dose of D3; if you're unsure what level is right for you, your doctor can check your vitamin D with a simple blood test.

When will I see results?

Vitamin D levels rise steadily over 4–8 weeks of daily use — many customers report improvements in mood and everyday energy along the way.*

Bone and immune support are long-term benefits that build over months, which is why D3/K2 works best as a year-round habit.*

Are there any side effects?

D3 and K2 are well tolerated when taken as directed. Because this is a high-strength D3 dose, don't combine it with other vitamin D products without checking your total intake.

If you take blood-thinning medication (especially warfarin), talk with your doctor before taking vitamin K2 — this one genuinely matters, as K2 interacts with how those medications work.

Founded By a U.S. Army Veteran

I served four years as a U.S. Army Infantry Officer. The Army taught me one lesson I’ve never let go of: you never cut corners on the people counting on you.

That’s why I started Luma Nutrition — real clinical doses, independently tested, made in the USA. Nothing goes in these bottles that I wouldn’t hand to my own parents.

If you ever have a question about our products, reach out. I read and respond personally.
