Are Your Vitamin D Levels Actually Where They Should Be?

You may already know that your vitamin D is low, or maybe no one has mentioned it. But here’s the thing, even if your doctor says that your levels are "normal," the levels might still be far from optimal.

On most lab reports, the reference range for vitamin D is anywhere from 30 to 100 ng/ml. But here's what they don’t always tell you. Anything under 50 is not actually ideal. So, if your levels come back at 31 or 32, you may be told that you're "fine," when in reality, your body could be functioning far below its best.

Why Vitamin D Is So Important

Vitamin D plays a crucial role in your overall health, not just for bones, but for your immune system, hormones, brain, and inflammation levels. It’s involved in:

• Modulating immune responses (which is especially important for anyone with autoimmunity)
• Supporting calcium absorption for strong bones and teeth
• Helping to maintain muscle strength and balance
• Supporting mood, brain clarity, and cognitive function

When your vitamin D levels are low, your immune system doesn’t function as smoothly, your bones may weaken over time, and inflammation can start to build. It can even affect your mood and energy levels.

Can You Just Get It From the Sun?

Yes, technically. Your body can make vitamin D when your skin is exposed to sunlight. But in real life, it’s just not that simple.

There are a lot of reasons why you may not be making enough D from sunlight alone:

• You live in a northern climate or don’t get outside regularly.
• You wear sunscreen (which blocks vitamin D production).
• You have darker skin (which naturally filters UV rays).
• It’s winter or cloudy for long stretches of time.

Even if you do get sun, it often isn’t enough to get your levels up to that 50+ optimal mark, especially if you're also not ingesting consistent food sources.

Foods That Contain Vitamin D (But Not Much)

Some foods contain small amounts of vitamin D, such as salmon, sardines, egg yolks, and fortified dairy or plant milks - but the amounts are minimal. You’d have to eat several servings per day, every day, just to make a dent.

That’s why, for most people, supplementation becomes necessary.

But Not All Supplements Are Created Equal

If you’re going to supplement, quality matters. You want a form of vitamin D that your body can actually use (such as vitamin D3, not D2), and you also want it paired with the right cofactors to help it work properly.

Why You Should Not Take Vitamin D Alone

Vitamin D helps your body absorb calcium from the food you eat or the supplements that you take, but here’s the catch:

If there’s not enough vitamin K alongside it, that calcium can end up in the wrong places such as your arteries or soft tissues, instead of your bones and teeth, where it belongs.

Let’s break it down:

• Vitamin D3 increases calcium absorption in your gut.
• Vitamin K1 and K2 help direct that calcium to the right places.
• Without vitamin K, calcium can build up in the arteries and contribute to stiffness or plaque.

So, while vitamin D is essential, taking it alone can actually create imbalances.

The Power of K1 and K2 

Vitamin K1 is often found in leafy greens, while K2 (especially MK-4) is harder to get from food. These forms of vitamin K are essential for activating proteins that transport calcium into your bones and out of your blood vessels.

K2, in particular, is what helps maintain arterial elasticity and supports long-term cardiovascular health, something that vitamin D alone can’t do.

This is why any high-quality vitamin D supplement should also include both K1 and K2.

What About GG? (And Why It’s a Big Deal)

One thing that sets certain formulas apart is a compound called geranylgeraniol (GG). GG is naturally made in the body, but levels decline with age and certain medications (such as statins).

Here’s why GG matters:

• It helps your body convert vitamin K into its most active form (MK-4).
• It supports cellular energy production.
• It helps your body make CoQ10, which is vital for heart and mitochondrial health.

In other words, GG helps make the entire vitamin D + K system work better.
