A forum about Transfer Factor...cool! I was doing some on-line research which is how I found you. My question is about gaining weight while taking TF. Specifically, I take Immunfactor 2 for EBV. I first took it about 2 years go when first diagnosed for a 3 month period and then one week out of the month (don't recall for how long). Eventually stopped it, slowly regained my strength and resumed my 'regular life', was even starting to exercise again...finally! I walked for 1 hour about 4 nights a week, and was feeling great, and continued to ramp up my time and speed. Well, after 3 months of walking, I started feeling sick, sore throat, swollen lymph nodes, fatigue... As hard as it is for me to understand, I guess walking is what made my EBV flair up. Walking gave me so much energy and vitality which is a great stress reducer, yet I guess it was too much stress on my body...who knows?! Anyways, so I have been on TF again for about 1.5 months, and my weight has shot up about 4-5 lbs almost overnight, and will not budge!! I am so frustrated, but I can't help but wonder if there is a link since it happened a week after starting the TF. I also started Beta Glucan again at this time. Has anyone else experienced weight gain on either of these supplements?
