The Shocking Truth About Vitamin D: It’s More Than a Vitamin

Are You Suffering From Low Vitamin D?

Imagine this: You’re dragging yourself through the day, even after getting a full 8 hours of sleep. Your mood is unpredictable—one minute you're snapping at your kids, the next you're feeling emotional for no reason. Coffee isn’t cutting it, and brain fog has become your daily companion. On top of that, you’ve been catching every cold that comes your way, and losing those stubborn pounds seems impossible.

Sound familiar? You might be dealing with low Vitamin D levels.

Most people think Vitamin D is just for bones, but it’s actually a powerful hormone that affects everything from your immune system to your mood, weight, and even hormones. And unfortunately, most women are walking around with dangerously low levels without even knowing it.

Vitamin D: More Than Just a Bone Booster

Vitamin D plays a role in so many critical areas of your health. It’s not just for strong bones. In fact, Vitamin D helps regulate key hormones like estrogen and testosterone, which makes it especially important for women during perimenopause and menopause.

But that’s not all! Vitamin D is crucial for maintaining a healthy immune system, and it also plays a big part in regulating your mood. Low levels of Vitamin D have been linked to depression and anxiety, which is why it’s often referred to as the “sunshine hormone.”

And here’s where it gets even more interesting—Vitamin D can impact weight management. When your levels are low, it can slow your metabolism and even throw off your hunger signals. Think of it as your body’s fuel gauge—when it’s out of sync, it’s hard to lose weight.

Why Are We All So Deficient?

You’d think with all the time we spend outside, we’d have plenty of Vitamin D, right? Wrong. Our modern lifestyle keeps us indoors more than we realize, and even when we do go outside, we’re usually slathering on sunscreen (which blocks the very UV rays we need to make Vitamin D!). Plus, food sources of Vitamin D are limited, so it’s tough to get enough from diet alone.

According to research, an estimated 1 billion people worldwide are deficient in Vitamin D. That’s a massive number! So, it’s not just about bones—it’s about overall health, hormones, and even your waistline.

Symptoms of Low Vitamin D

How can you tell if you might be low on Vitamin D? Here are some common symptoms to look out for:

  • Constant fatigue

  • Frequent illness

  • Muscle weakness or aches

  • Mood swings or feelings of depression

  • Difficulty losing weight

If any of these sound like you, it might be time to get your Vitamin D levels checked. Want to hear more about these symptoms and how Vitamin D could be the answer you’ve been looking for? Watch the full video to learn more about these hidden symptoms!

The Real-Life Power of Vitamin D

I’ve seen firsthand how powerful Vitamin D can be. Let me share a quick story about a woman I knew—a horse farmer in her 40s who spent plenty of time outdoors. One winter, she started getting sick frequently and was always tired. Her doctor found a concerning lump in her neck, but after some blood work, it turned out her Vitamin D levels were dangerously low.

After a short course of high-dose Vitamin D, her symptoms improved, the lump disappeared, and she avoided an unnecessary surgery. That’s how powerful this hormone can be.

How to Boost Your Vitamin D Levels

If you think you’re low on Vitamin D, the first step is testing. Ask your doctor for a 25-hydroxyvitamin D test, which will give you a clear picture of your levels. The goal is to get your levels between 50-80 ng/mL for optimal health. In functional medicine, we aim for this range because it’s where you’ll feel your best.

And if sunlight isn’t giving you enough, supplementation may be key. I always recommend Vitamin D3, which is the most bioavailable form. For many people, adding Vitamin K2 is helpful too—it ensures calcium goes to the right places in your body, like your bones, and not your arteries.

Get Your Vitamin D Checked

Have you been feeling tired, moody, or unable to lose weight? You might be dealing with a hormone imbalance, and Vitamin D could be the missing piece.

If you’ve been struggling and your doctor keeps telling you everything is "normal," it might be time to dig deeper.

II get it. I’ve been there myself, and I know how frustrating it can be when you know deep down that something just isn’t right.
