Why it matters
Why take vitamin D
Vitamin D works more like a hormone than a vitamin, and low levels are common, especially if most of your day is spent indoors. K2 makes sure the calcium vitamin D helps you absorb ends up where it belongs.
Your immune system
Vitamin D supports healthy immune function.*
Mood and balance
Vitamin D supports healthy mood and hormonal balance.*
Healthy arteries
K2 helps keep calcium where it belongs, supporting healthy arterial function.*
Take it with a meal that has some fat in it, since both D3 and K2 are fat-soluble.
The evidence
D3 absorbs calcium. K2 decides where it goes.

Read the full research summary
D3 and K2 work as a system. Vitamin D3 increases calcium absorption from the gut. Vitamin K2 activates osteocalcin and matrix GLA protein, proteins that anchor calcium into bone and prevent its deposition into arterial walls. Together, they direct calcium where it belongs.
The K2 in this formula is MenaQ7, a patented MK-7 form developed by NattoPharma, Norway, protected by U.S. and Canadian patents. MK-7 has a half-life of over 72 hours, meaning one daily dose maintains active K2 levels continuously.
At 5,000 IU, D3 is dosed at the clinically relevant level for raising and sustaining serum vitamin D in the optimal therapeutic range. We recommend monitoring serum levels every 60 to 90 days when supplementing at this dose.

Questions
Good to know.
Why take D and K together?
Vitamin D helps you absorb calcium, but it doesn't decide where that calcium goes. K2 (MK-7) directs it toward your bones and away from your arteries, so the two work best as a pair, the way your body uses them.
Is 5000 IU of D safe daily?
For most adults, yes, 5000 IU is a common daily dose used to correct the low levels that are widespread today. If you have a known condition or take other supplements, it's worth confirming with your doctor.
Should I take it with food?
Yes. Both D3 and K2 are fat-soluble, so take your softgel with a meal that contains some fat for the best absorption.
Should I test my vitamin D level?
Yes, it's easy to track. A simple blood test shows where you stand and how you respond over time, which makes dialing in the right dose straightforward.
