Do you take NAC with food or on empty stomach?

I have been taking my NAC with my antibioticsi and I take them on an empty stomach (2 hours after a meal).  Is this okay?  Or should you take NAC with a meal?  Ive read amino acids should be taken on an empty stomach as you absorb it better.

 Please advise!

I've always taken it on an empty stomach.
Started ABXi around 2/15/10 for CFSi. Positive IgGi, IgA, IgM for Cpni. Also HHV-6, CMV, EBVi. 400mg Doxyi, 250mg Azith MWF, Tinii pulses.
Could you please tell me what NACi is? I also haveCFS, HHV6, EBVi, Cpni, Positive for Lyme,MSi and a subclass 1& 4 deficiency. I'm on Amoxicillain 3-500 capi 3x day. Biaxin500 mg 2xday and just started Flagyli 2xday. I am also trying low dose Naltrexone . Just fulling my second rx of it and I see little to no difference will give it 1 more month. I'm sick as a dog watching my life pass before my eyes. Hubby also has Very High Iggi to Cpn now for over a decade.  Would sooooo love to see some imporovement going on 6 months agressive CAT. Hope I'm on the right track ...any feedback would be welcome. thanks much

 Hello kali,

some informations about NACi:< . I am sorry to hear that the improvment after 6 months of abxi is not as it was supposed to be.

Have you been tested for heavy metals? Heavy metals can be a reason why the abxi are not working as they should. 

best wishes,



Kali, If you 'hover' your cursor over that little 'I' next to some of the challenging words, you'll see a short explanation or definition appear. If you click on it, you'll get a few references to posts containing that word on this site.

NACi is N-Acetyl Cysteine, which is liver-protective. Most of us plan to take it continually, even after we finish therapy.

Interesting question. I have always taken NACi at least 2 hours away from my atb. I sometimes took it on empty stomach, sometimes with food, but I would like to know, if it can be taken with atb. Everything would be much easier then. In our country NAC is medicine, not supplement and it is written in its enclosed leaflet:

-NAC must be taken at least two hours away from tetracycline (not valid for doxycycline)

-reports about inactivation of atb by NAC are based only on in vitro trials when these two substances were mixed directly

-although above mentioned it is advised to use NAC at least two hours away from atb for safety reasons

-in vitro incompatibility was described for  polysynthetic penicillins, tetracyclines, cephalosporine and aminoglycosids

- so far incompatibility was not described for amoxicillan, doxycycline, erythromycine, thiamphenicol and cefuroxime
