☀️ Your Immune System Runs on Sunshine
But Let’s be real — for half the year, many of us barely see the sun. ☀️
Between long winters, short days, and life mostly spent indoors, Vitamin D deficiency is incredibly common in northern climates.
🧩 Why it matters:
👉 Vitamin D = simple, powerful immune support
Vitamin D helps your immune system recognize threats, reduce inflammation, and recover from stress or illness.
When levels drop too low (which they often do from October to April), your immune system can feel sluggish — or even start overreacting.
It’s amazing how many people feel a real shift in mood, energy, and immunity once they correct a deficiency — especially those of us living in places where sunshine is a luxury!
📚 What research shows:
- People low in Vitamin D are more likely to catch respiratory infections (BMJ, 2017)
- Adequate Vitamin D helps calm chronic inflammation (JAMA Network Open, 2021)
- Low Vitamin D has been linked to higher risks of autoimmune disease (Front Immunology, 2019)
💡 Simple ways to stay in range:
Ask your doctor for a 25-hydroxyvitamin D [25(OH)D] blood test
Most adults need around 1,000–4,000 IU daily (more if deficient)
Choose Vitamin D3 (not D2), and pair it with Vitamin K2 + magnesium for better absorption
Ideal range on labs: 75–125 nmol/L (30–50 ng/mL) — not too low, not too high
💬 Let’s talk:
Do you take Vitamin D year-round?
Have you ever tested your levels — or noticed a difference in how you feel when you supplement?
