How Much Vitamin D Should You Take?

Is Your Vitamin D Where It Should Be?
Have you checked your vitamin D levels lately?
If not, now’s the perfect time.
Vitamin D isn’t just a “sunshine vitamin”—it’s a year-round guardian of your bone health, immunity, and energy levels. But here’s the catch: levels can swing wildly with the seasons, typically peaking in late summer and dipping in the darker winter months. If your levels are low now—or even just borderline—it’s a warning sign that winter could leave you truly depleted.
And surprisingly, even those who spend time in the sun can be deficient. Why? Because vitamin D absorption and utilization differ from person to person, based on everything from gut health to genetics and age.
What’s the Optimal Level?
While a level of 40 ng/mL may be acceptable, science suggests that a more optimal range is 50–60 ng/mL, measured with the 25(OH)D blood test.
Here’s a general rule of thumb:
💧 For every 1,000 IU of vitamin D3, blood levels may increase by around 10 ng/mL. That’s why it’s so important to test your levels—and retest after a few weeks of supplementation to ensure you’re getting the benefits.
Winter is a Vitamin D Desert—Are You Covered?
If you live north of Atlanta, winter sunshine just isn’t strong enough to make adequate vitamin D through your skin. That’s where a high-quality, absorbable supplement becomes essential.
Most adults need 3,000–4,000 IU per day during the colder months just to maintain a protective level. But needs vary widely—some require more, some less. That’s why a flexible and precise solution is key.

Should You Pair Vitamin D with Vitamin K?
We’re often asked whether D and K should be taken together. It’s a good question—especially since vitamin D helps you absorb calcium, and vitamin K2 helps direct that calcium to your bones, not your arteries.

One More Thing: Always Check With Your Practitioner
For most of us, adding vitamin D is simple and safe. But for individuals with health conditions such as kidney disease, high blood calcium, or lymphoma, it's essential to work closely with a trusted provider.
