I started taking it for energy… turns out, it might be the quiet MVP of staying healthy.

I really appreciate you checking out my blog! Just so you know, some of the links in this post are affiliate links.

There’s absolutely no pressure to buy anything, but if you do, it genuinely helps support the time and love I put into writing these posts.

Let me start by saying: I didn’t exactly plan to become someone who reads the back of supplement bottles. I used to walk past the vitamin aisle like it was haunted—so many bottles, so many promises. Fish oil. Zinc. Something called ashwagandha. No thanks.

But then one day, I was scrolling through social media (as one does), and saw yet another person talk about how Vitamin D changed their life. More energy. Less brain fog. Fewer colds. Even better moods. I rolled my eyes a little but… kept reading.

And then—I kid you not—I saw a study headline: “Vitamin D may improve cancer treatment outcomes.”

Now, I don’t have cancer. I’m not even chronically ill. But that headline stopped me in my tracks. Because if something is strong enough to help people going through actual treatment, what could it do for me, just trying to survive meetings and not forget where I left my phone?

So I Did a Little Digging (and by that I mean obsessive Googling)

Turns out, Vitamin D isn’t just about bones or sunlight or “something your mom tells you to take.” It’s a full-on immune system hype-man. Research links healthy Vitamin D levels with:

• Stronger immune response

• Lower inflammation

• Better mood

• Reduced risk of certain cancers, heart disease, and even type 2 diabetes

One study I found from Harvard mentioned that people with higher Vitamin D levels had a lower risk of colon cancer. Another showed that low levels were common in people who struggled with fatigue. I was like—wait. Is this why I’ve been dragging myself through the day even after 8 hours of sleep?

I Got My Levels Tested (Spoiler: They Were Trash)

I went to my doctor and asked for a quick blood test. Sure enough, I was at 18 ng/mL—well below the “healthy” range of 30–50. She told me that a huge chunk of the population is Vitamin D deficient and doesn’t know it. Especially if:

• You work indoors (hi, 9–5 life)

• You wear sunscreen religiously (good for skin, not for D)

• You live in a cloudy area or it’s winter

• You have darker skin, which naturally blocks some UV rays

Check, check, check, check.

Enter: My Amazon Shopping Binge

I went online and found myself staring at 12 million Vitamin D products. Gummies, softgels, drops, even sprays. I tried a few, and here’s what actually stuck:

1. Sports Research Vitamin D3 5000 IU with Coconut Oil

☀️ Buy it here

This one’s my MVP. It’s got over 100,000 reviews and the softgels are tiny—easy to take, even when I’m running out the door with a protein bar in my hand. The coconut oil helps with absorption since Vitamin D is fat-soluble.

2. NOW Supplements Vitamin D-3 & K-2

🧠 Buy it here

K2 works hand-in-hand with D3 to make sure calcium goes to your bones, not your arteries. If you’re going higher dose, this combo is clutch.

3. MaryRuth’s Vegan D3 Drops

🌱 Buy it here

Great if you don’t do pills or prefer a plant-based option. I keep this one at my desk and add a drop to my water bottle during Zoom calls.

So…What Happened After I Started Taking It?

Okay, let me be real: it wasn’t a dramatic overnight miracle. I didn’t suddenly become a glowing, radiant being with boundless energy and abs.

BUT…

Within 2–3 weeks, I noticed I wasn’t hitting that 3 p.m. slump quite as hard. I was sleeping better. My brain wasn’t as foggy during morning meetings. And—this one surprised me—my mood just felt a little lighter.

I also didn’t get sick the way I usually do when the seasons change. No sore throat, no sniffles, no “ugh, is this allergies or am I dying?” moment.

And yeah, maybe it was placebo at first. But when I rechecked my levels three months later, they were back in a healthy range. So something was clearly working.

The Best Part? It’s Cheap, Easy, and Low-Lift

There’s a lot of health advice out there that feels… exhausting. Juice cleanses. Hardcore workouts. Giving up coffee (don’t even suggest it).

But Vitamin D? It’s one capsule a day. Or one drop under the tongue. That’s it. I can handle that.

And I like knowing I’m doing something good for my body without having to reorganize my entire life. Some days I even take it while still half-asleep and crawling toward the coffee maker. Mission: accomplished.

Quick Tips If You’re Gonna Try It:

1. Get your blood levels checked first. It’s a simple 25(OH)D test and your doc can help you decide how much to take.

2. Take it with food—ideally something with a little fat to help absorption.

3. Don’t overdo it. More isn’t always better. Stick to your doctor’s advice or the product’s dosage.

4. Track how you feel. Everyone’s different. You might notice changes in sleep, energy, mood, or immune health.

Final Thoughts: Sunshine You Can Swallow

I never thought a little yellow vitamin would become part of my daily routine. But here we are.

I still don’t have a fancy pill organizer or a “wellness altar” (although that does sound very LA chic). But I do have a tiny bottle of Vitamin D on my nightstand that reminds me: small things matter.

And sometimes, the smallest things make the biggest difference.

☀️ Now excuse me while I go stand in a patch of sunlight like a sleepy cat.
