We conducted a 12-week study to explore the effects of selenium supplementation on flu immunity in healthy adults aged 50-64. Participants were divided into groups receiving different selenium doses or no selenium at all.
The results indicated that selenium could have both positive and negative impacts on immunity against the flu vaccine, influenced by the amount and type of selenium consumed. This complexity highlights the need for careful consideration of the benefits and risks associated with selenium supplementation in boosting flu immunity.

No colds this winter

THIS STUFF WORKS! We began taking it to prevent colds/flu and for Seasonal Affective Disorder. Within two days, both my mood and alertness improved. We haven't caught a single cold, flu, or sinus infection this winter. I tell everyone about it – it really works!

Quick flu recovery

Pleasant results so far! I've been taking one capsule each morning until I acclimate. After being ill for 15 days with flu, I recovered rapidly with NAC. Soon after starting it, my energy surged – no more needing coffee! I am now back to one capsule daily and feeling great.

Awesome supplement, though perhaps a bit dodgy brand. I started using this mainly for endometriosis, and surprisingly, my period pain has significantly reduced. My children had the flu, and shockingly, I didn't catch it. This has truly been a miracle pill for me, although I encountered an issue with the last batch.

Boosts immunity
19 people found this helpful
Have not had a cold or flu since I started taking this! I would never be without it. It boosts immune health, and when I feel I am coming down with something, I take one or two NAC. As a result, I haven’t been ill for years. I ensure to sleep early and avoid refined sugars. This brand offers the best prices and is far less expensive than the GNC brand I used to buy. I, along with my mother and adult children, use iNACt. As a health educator, I see people with colds and flu daily. NAC is a key reason for my good health. My daughters used it at college, avoiding colds and flu, thus not losing class time. I also take it before flights to counteract the risk of picking up upper respiratory infections.

Effective for prevention
6 people found this helpful
Every site I consulted recommended it for prevention, and I started taking it myself. I gave some to family members exposed to the flu, including a baby and a 4-year-old who had it. Those exposed did not catch it, and the children with flu recovered within 24 hours. The initial carriers experienced full-blown flu symptoms for almost a week; one even developed pneumonia despite getting 'the shot.' This product reduces the likelihood of severe flu-induced pneumonia and is recommended from October until late spring, unlike flu shots which cannot eliminate flu. Although there was a warning regarding a small risk of lung damage, it is far less than risks associated with flu shots.
