Don't Ditch Your Vitamin D Just Because the Sun Finally Showed Up

☀ WELLNESS INSIGHT ☀ Spoiler: your body’s relationship with sunlight is… complicated. Here’s what your skin isn’t telling you. By Dr. Jana Bunsic, D.O. • Abundance Wellness Center • Morristown, TN |
Ah, spring. The birds are back. Your neighbors are mowing again at 7am. And that golden Tennessee sun is finally gracing us with its presence. Naturally, you might be thinking: “Great — I can stop taking my vitamin D supplement now.”
Not so fast, sunshine. Here at Abundance Wellness Center, we take a root-cause, functional approach to your health — which means we don’t just treat symptoms, we follow the science. And the science says: most of us are still deficient in vitamin D, even in summer. Let’s break down why.
The Sunlight Myth Most People Fall For
Yes, your skin produces vitamin D when exposed to UVB rays. But here’s what nobody tells you about that deal:
|
70%+ of Americans are vitamin D insufficient or deficient |
SPF 15 blocks up to 93% of UVB rays your skin needs to make D3 |
10–15 min of direct sun needed daily— only when UV index is above 3 |
|
|
Here’s the kicker: Even on a beautiful sunny day in East Tennessee, if you’re wearing sunscreen (as you should be), staying clothed, working indoors, or have darker skin tones — your body’s vitamin D production drops dramatically. The sun is out. Your levels may not be. |
Myth vs. Fact: What the Sun Actually Does for You
|
✗ |
Myth: “I’m outside every day, so I’m fine.” — Being outdoors doesn’t automatically mean meaningful UVB exposure. Time of day, cloud cover, and sunscreen all matter enormously. |
|
✓ |
Fact: UVB rays — the kind that make vitamin D — are only strong enough between roughly 10am–3pm, and only when the sun is high enough in the sky. That’s a much narrower window than most people realize. |
|
✗ |
Myth: “I’d know if I were deficient.” — Vitamin D deficiency is notoriously sneaky. Fatigue, brain fog, low mood, and weak immunity often get blamed on everything else first. |
|
✓ |
Fact: Vitamin D acts more like a hormone than a vitamin — it influences over 200 genes and supports immune function, bone density, mood regulation, and cardiovascular health. This isn’t a nice-to-have nutrient. |
Why We See Deficiency Year-Round in Our Patients
At Abundance Wellness Center, we run comprehensive functional labs — and vitamin D insufficiency shows up constantly, regardless of season. Indoor lifestyles, sunscreen use, poor gut absorption, and dietary gaps all contribute. Spring sunshine is lovely, but it’s not a prescription.
The holistic truth: if your levels were low in January, a few sunny days in April aren’t going to fix them. Vitamin D is fat-soluble, meaning it needs to be stored and built back up with consistent, intentional effort.
We target an optimal functional range of 70–100 ng/mL on a 25-OH Vitamin D test — well above the conventional lab cutoff of 20 ng/mL, which is frankly just enough to keep rickets away. That’s not the bar we’re aiming for.

💊 PHYSICIAN-FORMULATED SUPPLEMENT Vitamin D3 5,000 IU By Dr. Jana Bunsic, D.O. • $14.00 • lifechangingdoc.com Delivers 5,000 IU of high-potency cholecalciferol per softgel, formulated for maximum absorption and purity. No fillers, no shortcuts. Supports immune function, bone strength, and balanced mood. Take one softgel daily with a fat-containing meal. A note on Vitamin K2: Our Vitamin D3 5,000 IU intentionally does not contain K2. Too much supplemental K2 can be problematic, and the good news is that most people can get exactly the right amount from food. Dr. Bunsic recommends 1–2 servings of dark leafy greens daily — kale, spinach, collard greens — as your natural K2 source. It’s enough to do the job without the risk of excess. Clean, precise supplementation without the guesswork is exactly why our patients choose this formula. |
Vitamin D Doesn’t Work Alone: The Foundational Health Regimen
Here’s what separates a functional medicine approach from simply popping a pill: nutrients work synergistically. Vitamin D is most effective as part of a complete nutritional foundation — and that’s exactly what Dr. Bunsic’s Foundational Health Regimen is built around. Think of it as a four-part team where every player does something the others can’t.
|
|
Vitamin D3 5,000 IU The anchor. 5,000 IU of high-potency D3 per softgel. Take with food — specifically with your fish oil — for optimal fat-soluble absorption. |
|
|
Ultra Omega-3 Fish Oil The fat that makes D3 work. 500 mg EPA + 250 mg DHA per serving, molecularly distilled for purity — free from heavy metals and PCBs. Vitamin D is fat-soluble, so pairing it with quality omega-3s at mealtime significantly boosts absorption. Bonus: supports heart health, brain function, and joint mobility.* |
|
|
Mens Multi V with Methyl B / Women’s Multi Vitamin with Methyl B The nutritional foundation. Comprehensive multivitamin with Albion™ TRAACS™ amino acid chelates for superior mineral absorption. Fills dietary co-factor gaps your body needs to actually put vitamin D to work — including methylated B vitamins for energy and cardiovascular support. Take with food alongside your D3 and fish oil.* |
|
|
Bacteria Balance Probiotic The gut that processes it all. 50 billion CFU across 12 synergistic strains. A thriving microbiome is essential for nutrient absorption — but unlike the other three products, the Bacteria Balance Probiotic should NOT be taken with meals. Take 2 capsules at bedtime, or at least 1.5 hours away from eating, so the probiotics can colonize without competing with digestion. Feed your microbiome daily with plenty of fiber — think vegetables, legumes, and whole grains — to create the internal ecosystem where good bacteria flourish.* |
The rhythm is simple: take your Vitamin D3, Ultra Omega-3 Fish Oil, and multivitamin together with a meal. Then take your Bacteria Balance Probiotic at bedtime, away from food, with a glass of water. Same four products, two simple moments in your day — and your body gets everything it needs to thrive all year long.
