How much D3 and K2 does your product have per serving (12 drops)?
There is 1,000 IU of Vitamin D3 and 25 mcg of Vitamin K2 (MK-7) in 12 drops.
What is the RDA (recommended daily allowance) for Vitamin K
Vitamin K2 doesn't currently have an established Daily Value, which is why you'll see '†Daily Value Not Established' on our label, that's standard for this nutrient, not specific to our formula. Each 12-drop serving provides 25 mcg of Vitamin K2 (MK-7), formulated to work alongside our Vitamin D3.
How long does it take for one's Vitamin D level to be normal?
Vitamin D3/K2 is designed for daily maintenance, not as a treatment for diagnosed deficiency. If you're concerned about your levels, your doctor can test and advise on what's right for you; many people take this supplement daily as part of a consistent routine to support their existing levels.
What form of D3 is used?
Our Vitamin D3/K2 supplement uses cholecalciferol from lanolin.
Does Vitamin K2 interact with blood thinners or other medications?
Vitamin K2 can interact with warfarin and other vitamin K antagonist blood thinners. If you take blood-thinning medication, talk to your doctor before starting this or any Vitamin K–containing supplement.
Is this vegan?
No. Our Vitamin D3 is sourced from lanolin (derived from sheep's wool), which is the most bioavailable and well-studied form of D3. If you're looking for a vegan D3 option, we recommend checking the label carefully, as most vegan D3 (D2 or lichen-sourced D3) has different absorption research behind it.
What's the best time of day to take it?
Vitamin D3 and K2 are fat-soluble, so they're best absorbed when taken with a meal that contains some fat. Many people find it easiest to take with breakfast or their largest meal of the day, but consistency matters more than the specific time.
Why is the bottle dark/amber-colored?
The bottle is dark to protect the formula from light exposure, which can break down potency over time. It's a packaging choice for stability, not a change to the formula itself.
What does it taste like, and how do I take it?
Shake well, then place 12 drops under your tongue or mix into water or a beverage. The MCT oil base has a mild, neutral taste, most people find it easy to take straight or blended into their morning drink.
