Introduction
Have you ever noticed you feel happier after spending time in the sun? That warm, good feeling isn’t just in your head. Something real is happening in your body—and it has to do with vitamin D3!
Many people today spend lots of time indoors, working on computers or using phones. This means they may not get enough natural vitamin D, which is super important for your health.
At On Point Chiropractic, we care about helping you stay healthy by asking good questions. One great question is: Am I getting enough vitamin D3? Let’s learn what vitamin D3 does, how you can get it naturally, and when vitamin D supplements might help.
What Is Vitamin D3, Anyway?
Vitamin D3 (also called cholecalciferol) is a vitamin your body needs to stay strong and healthy. It helps your body use calcium for strong bones and teeth. It also supports your immune system, keeps your mood balanced, and plays a role in your energy levels.
The amazing part? Your body can actually make vitamin D3 from sunlight!
Natural Sources of Vitamin D3
The best way to get vitamin D3 is through sun exposure. When the sun’s UVB rays hit your skin, your body begins making D3 on its own. Around 10–30 minutes of sun a few times a week is usually enough, depending on your skin tone, where you live, and how much time you spend outside.
There are also foods with vitamin D3, like:
- Fatty fish (like salmon or tuna)
- Egg yolks
- Fortified foods like milk or cereal
But most people don’t get enough D3 from food alone, which is why sunlight (and sometimes supplements) are important.
Who Might Need a D3 Supplement?
Many people have vitamin D deficiency without even knowing it. You might need extra help from a vitamin D3 supplement if:
- You’re indoors most of the time
- You live in a place with cold or cloudy weather
- You have darker skin (which blocks more UVB rays)
- You wear sunscreen often (which can block vitamin D)
- You are older or have certain health conditions
- You eat a plant-based diet (with no animal sources of D3)
A high-quality vitamin D3 supplement can help keep your levels steady and support your overall health.
Why Sunshine Still Matters
Even if you take a vitamin D3 supplement, the sun still does more for your body. Natural light helps with your sleep schedule, makes you feel happier by boosting serotonin, and encourages you to move around outside.
Sunshine and movement are key parts of wellness—especially when paired with the right nutrients.
Conclusion: Support Your Health with Vitamin D3
