I have been looking into different things to try and strengthen my immune system, i have a few things on my to do list. Saw my doc today and he suggested a product called Ribraxx and the way he explained it was that they have taken the active ingredients out of rice bran and mushroom extract but, when i priced it, it came to over $200 for 30 sachets and the dose is between 1-3 sachets a day, its suppose to increase nk cells etc and supposedly has good science behind it. Sounds like a good product but not at that price. Immunovir is on my list and i have a script from my doc but, i think im going to put it on hold for another month or so as i have seen iherb have AHCC Jarrows brand on a good special, 30x500mg for $18. The doses i have seen in studies using AHCC is around that 2000mg. So 4 bottles should last a month and cost $75. So my immune modulation plan is AHCC 1000mg twice a day with astragalus extract 1000mg twice a day. Lets see what happens next. I am increasing antivirals doses for awhile too. cheers!!!
