Expert Tips

At the first sign of onset of a cold (scratchy throat, sneezing) or flu (sore throat, body aches, fever, chills, sweats) – start these supplements and treatments as soon as possible. 

 

Vitamin D: Take 50,000 – 100,000 international units daily up to 3 days max (20,000-50,000 international units daily for children). While vitamin D toxicity is rare, it’s wise to check your baseline levels and periodically test if you are taking high doses for extended periods. 

 

  • A superior source of Vitamin D is sublingual (under the tongue) using 10,000 international units daily. 

 

  • For ongoing vitamin D supplementation, take one Ortho Molecular K-force Vit D/K2 5,000/180 by mouth with food daily.  

 

Vitamin C: Take 1,000 mg every 4 hours, if your stomach can tolerate it. 

 

  • 1000 mg per tsp of Quicksilver Scientific Liposomal Vitamin C. Hold under your tongue for 30-60 seconds then swallow. 
  • Use 3-4 times daily for acute illness, once daily for general immune support. 

 

Zinc: Take 30-60 mg daily for a week. 

 

  • Take Quicksilver Scientific Immune Active Zinc Ionophore, which contains quercetin to help drive zinc intracellularly where it is needed for immune support.  

 

Vitamin A: Take 30,000-100,000 IU sublingual daily for 3 days. 

 

  • Use Genestra brand “A-mulsion.” One drop = 3,000 IU, so take 30 drops (90,000 units) under the tongue daily for 3 days. 

 

Nasal Washing: This is a safe, inexpensive and non-invasive way to prevent viral infections with many options including: 

  • Saline – Research supports the effectiveness of basic nasal irrigation using saline (salt water), which can be administered using a Neti Pot or bulb syringe. There are numerous online resources providing guidance on this practice. Add a pinch of baking soda to the saline solution to helpreduce any potential discomfort from the irrigation. 

 

  • Povidone-iodine nasal spraysShown to effectively decrease viral load.  

 

  • Xclear – Combines Xylitol (inhibits viruses from adhering to the mucosal lining of the nose) and Grapefruitseed (GSE) Extract, which is a known antimicrobial. 

 

  • Dosing – For all nasal sprays, use one squirt in each nostril twice daily (more often with known exposure or high-risk settings). 

 

Argentyn-23 Throat Spray + Nasal Spray: Follow instructions on the bottle and spray to the back of the throat and gargle with it.

  • This is colloidal silver which kills EVERYTHING and is a must-have at home during cold and flu season. 

  •  One squirt in each nostril twice daily. 

 

Biocidin liquid: Essential if you develop a viral infection in the lungs or if you have a home nebulizer.  

  • Nebulize 1cc of normal saline with 10 drops of Biocidin liquid or ½ cc of normal saline and ½ cc of food grade hydrogen peroxide. 

 

Andrographis (optional): Known for its anti-inflammatory, antiviral and immune-boosting effects, take 60 mg (which is three times the normal dose) of andrographis extract capsules three times per day.  

 

Elderberry (optional): This can reduce the severity and duration of cold and flu symptoms. Try DaVinci liposomal Elderberry extract 2 mL daily (hold under the tongue for 30-60 seconds then swallow. 

 

Oscillococcinum: A homeopathic supplement by Boiron used at the first sign you suspect influenza (especially if it’s going around, or folks at home, school or workplace have had it). 

 

Cold Calm: This homeopathic supplement by Boiron is perfect if you suspect the common cold. Other homeopathic treatments are Meteoric Iron Prunus Immune Support Pellets by Uriel Pharmacy. 

 

Essential Oils: Try “Thieves” by Young Living or “On Guard” by doTerra. Both oils are known for their disinfectant and immune-boosting properties. Diffuse the house with these regularly to purify the air in your home. 

 

Disinfectant: Try making your own, chemical-free disinfectant at home. 

  • Get a 12-ounce brown spray bottle from Amazon and fill it ¾ with reverse osmosis or distilled water and ¼ with vinegar.  

  • Leave a little space and add 1-2 drops of liquid dishwashing detergent and about 30 drops of Thieves essential oil or On Guard by doTerra.  

  • Use this mixture to spray down doorknobs, fridge/freezer handles, faucets, and any surfaces frequently touched to help eliminate germs. 

Fire Cider: This is a traditional tonic made from spicy and pungent ingredients steeped in vinegar.  

  • You can find recipes online or purchase at a health food store; however, I steep a combo of apple cider vinegar, garlic, ginger, and cayenne. 

 

Remember, staying informed about the latest health recommendations and adjusting your habits accordingly can make a substantial difference in staying healthy throughout the season. By prioritizing these strategies, you empower yourself to navigate the season with greater resilience and well-being. Here’s to a healthy and flu-free season ahead!
