At Now Health, many of our patients are working on two important goals at the same time:
It’s common to wonder whether supplements like vitamin D, vitamin K, or products such as AlgaeCal are safe when taking a blood thinner.
The answer depends on which medication you take and your individual health picture—but most people can support bone health safely with a thoughtful plan.
Let’s walk through it together.
Bone loss accelerates after menopause and later in life. For many Alaskans, long winters, less sun exposure, and reduced outdoor activity make bone support even more important.
Strong bones are about more than density. They depend on:
Supplements are only one part of the picture.
This is where confusion often starts.
Warfarin works by blocking vitamin K–dependent clotting factors.
Because of this, large changes in vitamin K intake can affect INR levels.
Patients on warfarin need a consistent intake of vitamin K and guidance before adding supplements.
Examples include Eliquis, Xarelto, Pradaxa, and Savaysa.
These medications work differently. They directly block clotting proteins and are not affected by vitamin K intake.
That means moderate vitamin K from food or supplements usually does not interfere with these medications.
This is an important distinction.
Vitamin D supports:
There is no meaningful interaction between vitamin D and Eliquis or similar medications.
At Now Health, we usually aim for a vitamin D level in a functional range that supports bone and immune health, then adjust dosing based on labs.
Vitamin K helps activate proteins that move calcium into bone instead of soft tissue.
In patients on Eliquis or other DOACs:
In patients on warfarin, vitamin K intake must stay consistent.
Most AlgaeCal formulas contain:
For patients on Eliquis, these ingredients are generally safe when:
However, calcium supplements are not always necessary. Many people can meet their needs through food, and excessive calcium may not be helpful.
This is where individualized care matters.
We look more closely when someone has:
In these cases, we adjust the plan carefully.
Instead of jumping straight to supplements, we usually take these steps:
Vitamin D, calcium, magnesium, kidney function, and bone density when appropriate.
Protein intake
Strength training
Balance work
Outdoor activity when possible
Even short winter walks with traction cleats help more than people realize.
Only what is needed, at doses matched to labs and symptoms.
Vitamin D and vitamin K at typical doses do not increase bleeding with Eliquis.
Still, any patient on anticoagulation should report:
These deserve prompt evaluation.
Supporting bone health while taking a blood thinner is not only possible—it is important.
The key is a steady plan that includes:
No one-size-fits-all approach works here.
We created a Now Health two-page guide called:
👉 “Bone Health Supplements While on Blood Thinners”
It includes dosing ranges, safety checklists, and questions to ask at your visit.
