Vitamin D + K2 Liquid

Thorne Vitamin D + K2 Liquid provides 1,000 IU (25 mcg) of vitamin D3 and 200 mcg of vitamin K2 as MK-4 per two drops, in an MCT-oil base. It’s a convenient option for people who prefer drops over another capsule. Product details

Vitamin D helps your body absorb calcium and supports normal muscle and immune function. Vitamin K helps activate proteins involved in bone health and normal blood clotting. They have complementary jobs, but that doesn’t mean everyone needs extra amounts of both. Vitamin D · Vitamin K

My wife and I both take this. It has a place in our household—not just on my store shelf. That’s our personal routine, not a recommendation that everyone needs extra vitamin D and K.

Before adding vitamin D, I want to know what’s already in your routine. Your multivitamin may have gotten there first.

Let’s talk about it.

I like the flexibility of drops. They’re easy to count, don’t add another capsule, and allow smaller dose adjustments when there’s a reason to make them.

But flexibility isn’t an invitation to freestyle the dose.

For those of us eating less on a GLP-1, paying attention to nutrition makes sense. That doesn’t automatically mean the medication has depleted vitamin D, or that everyone needs this bottle.

When there’s a clinical reason to check vitamin D levels, the results can help guide treatment. Routine testing isn’t recommended for every otherwise healthy adult. I’d rather have a reason for the test and the supplement than chase a number because the internet told us to. Testing guidance

Already taking Basic Nutrients 2/Day? Read this part.

Two capsules already provide 2,000 IU of vitamin D3 and 400 mcg of total vitamin K. Adding two drops of this liquid brings those supplement totals to 3,000 IU of vitamin D3 and 600 mcg of vitamin K. That’s arithmetic—not a recommendation to take both. Multivitamin label

And because these vitamins come together, increasing the drops increases both D and K2. If someone needs only more vitamin D, a combination product may not be the best fit.

My reason for carrying it is choice: a liquid option for someone with a clear reason to supplement. It’s not an automatic add-on to the multivitamin, and it doesn’t replace the multivitamin’s other nutrients.

Thorne’s directions are two drops one to three times daily, or as recommended by your healthcare professional. The appropriate amount depends on what you already take and why you’re supplementing.

Invert the bottle and let it dispense individual drops. Count drops, not a dropperful. It can be added to food or a beverage. Do not refrigerate. Directions

For most adults, the usual vitamin D upper limit is 4,000 IU daily from food and supplements combined, unless a clinician is supervising a different dose. Taking the highest label dose alongside a multivitamin can exceed that amount. Intake guidance

If you take warfarin or another vitamin K antagonist, don’t start this product or change your vitamin K intake without your anticoagulation clinician’s guidance. Vitamin K can change how that medication works. Interaction guidance
