An Invention of Prevention: Discovering a Successful Flu Formula

The Story of Immune VF1

by Philip K. L. Lee, BSc ND

There is a myth that natural medicine typically takes too long to work.

All-natural Immune VF1 works fast to help prevent seasonal infections from developing, when taken as directed at the first onset of viral symptoms.

When I started my clinical practice many years ago, there was no supplement or procedure I could confidently recommend to my patients to prevent or alleviate their cold or flu problems. My naturopathic medical training made me aware of herbs and vitamins that can boost the body's immune system and in this way help with cold symptoms. In 2011, I started researching for herbs that had anti-viral properties, especially against cold & flu viruses.

I was determined to find solutions to prevent or resolve cold or flu fast. No one likes feeling sick for the typical 10 days of a cold or flu virus infection! Over time, I narrowed my formula down to the most effective ingredients and maximized the dosage to increase efficiency. I knew the herbs were all well studied and safe to use.  Patients have reported very effective results with VF1.

Most people that use VF1 have been able to avoid seasonal infections, either when taken at first onset of symptoms or as a preventive immune boost. Healthy people taking VF1 after getting sick can resolve symptoms within 24-36 hours typically.

Traditionally, when people get a cold/flu virus they look for whatever symptomatic relief they can find with mass-market over the counter medications and expect to suffer as usual for several days.

But if you want the real solution for seasonal infections, you need to try Immune VF1 — the professional strength anti-viral herbal supplement for fast relief.
