Why I Don’t Recommend Vitamin D Supplements as a Naturopathic Doctor (And What I Do Instead)

Vitamin D has become one of the most commonly recommended supplements in modern health care. Low energy? Take vitamin D. Feeling down? Take vitamin D. Labs a little off? Take vitamin D.

It’s often treated like a harmless, one-size-fits-all solution. But here’s the truth: Just because something is popular doesn’t mean it’s foundational. And just because something is “low” on a lab doesn’t mean your body is asking for more of it in pill form.

As a naturopathic doctor, I don’t routinely recommend vitamin D supplements. And when I explain why, it usually surprises people.

Let’s talk about it.

Vitamin D Isn’t Actually a Vitamin

One of the most important things to understand is that Vitamin D behaves more like a hormone than a vitamin.

It plays a role in immune function, mood, bone health, and inflammation. But the body doesn’t just “use it” like a nutrient you eat.  It regulates it, converts it, activates it, and stores it in very specific ways.

Which means…

When levels are off, it’s often not a deficiency problem. It’s a regulation problem.

Low Vitamin D Is Often a Symptom—Not the Root Cause

In my clinical experience, when someone has low vitamin D, I don’t immediately think, “You need more vitamin D.”

I think:

Why isn’t your body making or activating it properly?

What’s happening in your liver or kidneys (where activation occurs)?

Are you inflamed, stressed, or depleted?

Are you actually getting sunlight but not utilizing it?

Are you mineral deficient?

Do you have gut issues?

Is your body full of toxic metals?

Because here’s what I see over and over again:

You can give someone vitamin D supplements…and their body still doesn’t know what to do with it.

Sunlight Is the OriginalMedicine

Vitamin D is meant to come from sunlight interacting with your skin, not from a capsule. The vitamin D in the capsule is  a synthetic hormone that is quite different from vitamin D that your body creates on it’s own.

That process does more than just “increase a number” on your labs. It:

Signals your circadian rhythm

Regulates your nervous system

Supports hormone balance

Anchors your body to natural cycles

When we bypass that process and go straight to supplementation, we miss the bigger picture. We’re trying to replace a full-body experience… with a single nutrient.

More Isn’t Always Better

Because vitamin D is fat-soluble, it accumulates in the body. And in practice, I’ve seen that more is not always better. Supplementation with vitamin D, especially high doses, can completely deplete your magnesium and potassium levels.  These are two super important minerals that you need so that you don’t have a heart attack.

Over-supplementation can:

Disrupt calcium balance

Contribute to calcification in tissues

Create imbalances with otherminerals (especially magnesium)

And here’s where this gets even more important, magnesium plays a critical role in vitamin D metabolism. Yet many people are already deficient. As we know, magnesium deficiency is incredibly common and tied to stress, poor sleep, and blood sugar imbalance. So what happens when we push vitamin D without addressing magnesium? We create more imbalance, not less.

The Supplement Industry Isn’t Built on Individualization

Another layer to this conversation is quality and intention. Not all supplements are created equal. In fact, many are poorly absorbed, contaminated, and/ or filled with unnecessary additives

And without proper guidance, people often take supplements they don’t actually need, which can do more harm than good. This is why I don’t believe in blanket recommendations. Your body isn’t generic and your protocol shouldn’t be either.

What I Do Instead

Instead of defaulting to vitamin D supplements, I focus on helping the body restore its ability to regulate itself.

That looks like:

1. Reconnecting with Sunlight

Getting consistent, natural light exposure, especially in the morning.

2. Supporting Mineral Balance

Ensuring adequate magnesium and other cofactors so the body can actually use what it has.

3. Reducing Inflammation + Supporting the Liver

Because activation of vitamin D depends on internal health not just intake.

4. Detox heavy metals

A toxic body will suck your vitamin D dry

5. Looking at the Whole Person

Sleep, stress, digestion, nervous system—all of it matters.

This Isn’t About Avoiding Supplements

There are absolutely times and places where supplementation can be supportive.

But it should be intentional, personalized, and root-cause driven Not just, “Your level is low—take this forever.”

A Different Way to Think About Your Health

Your body is not deficient by default. It’s communicating.

And when we slow down enough to listen, we often find that what looks like a deficiency is actually an invitation to go deeper. To restore rhythm. To rebuild resilience. To support the systems that were designed to keep you well in the first place.
