Thanks Fren! The article on Rockwell's site states that NAC is even more effective than Vitamin D!

NAC Inhibits Viral Replication

The idea that NAC can be helpful against viral infections is not new. Previous studies have found it reduces viral replication of certain viruses, including the influenza virus. As reported by board-certified nutritionist Joseph Debé:6

“NAC was tested in a 6-month human study7 of influenza. It was a randomized, double-blind, placebo controlled trial involving 262 people. Half of the subjects received 600 mg of NAC, the other half received placebo, twice daily for 6 months.


NAC was found to improve immune function and reduce the severity of influenza infections. Both groups had similar infection rates with A/H1N1 virus influenza. However, whereas 79% of placebo-treated people had symptomatic infections, only 25% of subjects treated with NAC were symptomatic!


There were a total of 99 flu-like episodes (symptomatic periods) that occurred in 62 people in the placebo group over the 6 month study. 48% of these were classified as mild, 47% were moderate, and 6% were severe.


In the NAC group, 46 flu-like episodes occurred in 37 subjects. 72% of these were mild, 26% were moderate and only 2% severe. There were many fewer days of being bedridden in the NAC group.”

It’s worth noting that the number needed to treat (NNT) in the study8 cited by Debé is 0.5, which means for every two people treated with NAC, one will be protected against symptomatic influenza.

That’s significantly better than influenza vaccines, which have an NNV (number needed to vaccinate) of 71,9 meaning 71 people must be vaccinated to prevent a single case of confirmed influenza.** It’s even better than vitamin D, which has an NNT of 33.10 Even among those with severe vitamin D deficiency at baseline, taking vitamin D still had an NNT of 4.**

I take D3+K2, 4000 IU's a day. I've been taking it for over a year straight, with taking a day or two off every so often just to help my body regulate. I've been told by my (then) doctor in the past that I needed more Vitamin D, so I did some research and found that K2 is essential for helping the body use D more efficiently.
