My Personal Story

What began as a personal search for better health, quickly turned into a passion, and eventually, a mission.

Most likely, like many of you out there, I was looking for answers considering my physical health: for me that meant not being sick all the time, a relieve for my chronic sinusitis, not being able to gain weight caused by IBS and I can carry on my list. Eventually my search to improve my health led me to 4Life and it's innovative Transfer Factor products.

At first I was very sceptical (as I always am) but after struggeling with my physical health and it being a major problem in my day to day life, I figured it was worth a shot. The results surprised me and soon, I knew I had to share this with others. This is where it all began for me.
