How to Strengthen Your Immune System Before Cold and Flu Season: Habits, Supplements, and IV Therapy

This is one of my favorite times of the year to write about health—because there’s so much to say when it comes to protecting your immune system as the weather cools and the holidays approach. Between cozy nights, seasonal treats, and kids bringing home every sniffle from school, this is the season where preparation makes all the difference.

The truth is, waiting until you feel that first scratchy throat is too late. Now is the time to ground yourself in healthy habits, prepare your supplement cabinet, and set your immune system up to be strong, resilient, and ready for whatever the season throws your way. At Peak Health Institute, we want to make that easier, which is why we’re offering 15% off select immune supplements all month long.

Why Immune Prep Matters Now

Cooler weather means more time indoors, less vitamin D from sunshine, and more exposure to circulating viruses. Pair that with sugary holiday treats, stress, and busy schedules—and you’ve got the perfect storm for lowered defenses. Supporting your immune system before illness strikes gives you the resilience to recover faster and, in many cases, avoid illness altogether.

Top 5 Habits to Strengthen Your Immune Health

1. Prioritize sleep: Aim for 7–9 hours to let your body repair and recharge. Being in sleep debt lowers your natural killer cells and your immune systems robust ability to manage a virus.
2. Balance nutrition: Reduce processed sugar and load up on colorful fruits and vegetables full of antioxidants. Now is a great time for a 30 day elimination diet to clear out any yeast or
   bacterial overgrowth before we jump full fledged into the holiday season!
3. Stay hydrated: Proper hydration supports cellular function and lymphatic flow. Remember, hydration is not just water. Minerals play an integral part in being adequately hydrated. At PeakHealth Institute, one of our fan favs is Quinton Isotonic as it packs all of the essential minerals your cells need for optimal function.
4. Move daily: Regular exercise boosts immune surveillance and resilience.
5. Stress management: Meditation, breath work, or simple walks calm the nervous system and improve immune readiness.

Trust me, your habits matter a lot more than you think. There is no dodging every single germ during this time of year, but the stronger your immune resiliency is, the lesser intensity and duration of any pesky upper respiratory infections.

Top Supplements to Support Your Immune Health

When symptoms hit, the last thing you want is to scramble for what you need. Here are our top recommendations for a strong immune arsenal this season:

• Immune Charge: A potent blend to activate the body’s defenses during early signs of illness. This is a great preventative daily supplement and I always double up for a few days when I feel those first signs of illness coming on.
• Vitamin D3: Essential for immune function, especially as sunlight decreases.
• 5 Defenders (Comprehensive Immune Support): Mushroom-based immune support with broad-spectrum benefits. This is a great daily staple during the fall and winter months.
• OrthoMune: A great daily support including vitamin C, vitamin D, zinc, Quercetin, and NAC. Not only is this a great daily immune support but it decreases inflammation and supports respiratory health as well.
• Viracid: Supports rapid immune activation and shortens illness duration. This one I start at the sign of cold or flu.
• Virakid: Kid-friendly formula to support your children’s immune defenses. This one is a friendly chewable kids vitamin and has the added bonus of making their tongue purple which definitely increases compliance!

Remember as always, it’s important to discuss these formulas with your provider to determine which are best suited for your body and be sure they don’t interact negatively with any medications you’re currently taking.
