Immune System Tune-up
Most people reach for Vitamin C and Zinc when they feel a cold coming on, but there are two other heroes in the mix that might even help more!!!
Vitamin D and a top notch gut microbiome!
Vitamin D levels naturally drop in fall → more colds.
🐟 Food Sources (these aren’t huge, but every bit counts)
  • Fatty fish: salmon, mackerel, sardines, tuna.
  • Cod liver oil (super concentrated, but an acquired taste).
  • Egg yolks.
  • Beef liver.
  • Fortified foods: milk, plant-based milks, orange juice, cereals.
💊 Supplements
  • Vitamin D3 (cholecalciferol) is better absorbed than D2.
  • Often paired with vitamin K2 (helps calcium go to bones, not arteries).
  • Typical maintenance: 2,000 IU daily, but many need higher based on labs
Vitamin D isn’t really a vitamin—it’s a hormone precursor. Your liver and kidneys turn it into calcitriol, which regulates over 200 genes, including ones for immunity, bone health, and even mood.
The Gut!!
DID YOU KNOW: 70% of your immune system lives in your gut. That’s why gut-friendly foods (fermented or fiber-rich) are basically the Wi-Fi router for your immunity
  • Load up fermented foods (sauerkraut, kefir, miso) to prime gut immunity.
  • Take a good probiotic and fill up in good fibers
  • look into local sources that make "Fire Cider"
  • Garlic = Natural Prebiotic: Garlic, onions, leeks, and asparagus are all rich in inulin, a prebiotic fiber. Eat them → your microbes thrive → immunity thrives.
Zinc + Vitamin C + gut health = your real immune squad.
