administering to a patient being treated for a disease selected from the diseases where glutathione is involved and/or in which thiol (—SH) reduction/oxidation (redox) switches play a role, or diseases in which the antiproliferative and pro-differentiating effect, antioxidant effect, or anti-inflammatory effect of NAC is utilized, a combination consisting of one or more excipients and active agents consisting of:
(i) NAC;
(ii) selenium in the form of selenomethionine (SeMet); and
(iii) melatonin (Mel)
and/or physiologically acceptable salts thereof,
wherein the combination is administered orally at a daily dosage weight ratio of NAC to SeMet to Mel of 12,500:1:50 to 37,500:1:66.67, or the combination is administered epicutaneously at a weight percent ratio of NAC to SeMet to Mel of 50:5:1 to 300:30:1.

3 . The method of claim 1 , wherein the diseases in which the antiproliferative and pro-differentiating effect of NAC is utilized consist of benign and malignant neoplasia.
4 . The method of claim 1 , wherein the diseases in which the antioxidant effect or anti-inflammatory effect of NAC consist of one or more of: chemical and/or infectious hepatitis, chronic obstructive pulmonary disease or asthma.
5 . The method of claim 1 , wherein the diseases in which the antioxidant effect or anti-inflammatory effect of NAC is utilized consist of one or more of: vitiligo, alopecia or psoriasis.
6 . A method of providing increased efficacy of N-acetyl-L-cysteine (NAC) in the treatment of diseases where glutathione is involved and/or in which thiol (—SH) reduction/oxidation (redox) switches play a role, wherein the diseases consist of one or more of: diseases causing suboptimal immune response and/or HIV/AIDS, cataracts, radiation poisoning, mal-nutritive states, arduous physical stress, trauma, burns, bipolar disorder, major depressive disorder, or schizophrenia the method comprising:
administering to a patient being treated for a disease selected from the diseases where glutathione is involved and/or in which thiol (—SH) reduction/oxidation (redox) switches play a role, a combination consisting of one or more excipients and active agents consisting of:
(i) NAC;
(ii) selenium in the form of selenomethionine (SeMet); and
(iii) melatonin (Mel)
and/or physiologically acceptable salts thereof
wherein the combination is administered orally at a daily dosage weight ratio of NAC to SeMet to Mel of 12,500:1:50 to 37,500:1:66.67, or the combination is administered epicutaneously at a weight percent ratio of NAC to SeMet to Mel of 50:5:1 to 300:30:1.
7 . A method of providing increased efficacy of N-acetyl-L-cysteine (NAC) in the treatment of diseases in which the antioxidant effect or anti-inflammatory effect of NAC is utilized, the method comprising:
administering to a patient being treated for diseases in which the antioxidant effect or anti-inflammatory effect of NAC is utilized, a combination consisting of one or more excipients and active agents consisting of:
(i) NAC;
(ii) selenium in the form of selenomethionine (SeMet); and
(iii) melatonin (Mel)
and/or physiologically acceptable salts thereof
wherein the combination is administered orally at a daily dosage weight ratio of NAC to SeMet to Mel of 12,500:1:50 to 37,500:1:66.67, or the combination is administered epicutaneously at a weight percent ratio of NAC to SeMet to Mel of 50:5:1 to 300:30:1.
8 . The method of claim 7 , wherein the diseases in which the antioxidant effect or anti-inflammatory effect of NAC is utilized consist of one or more of: chemical and/or infectious hepatitis, chronic obstructive pulmonary disease or asthma.
9 . The method of claim 7 , wherein the diseases in which the antioxidant effect or anti-inflammatory effect of NAC is utilized consist of one or more of: vitiligo, alopecia or psoriasis.
10 . The method of claim 1 , wherein the combination is administered orally at a daily dosage weight ratio of NAC to SeMet to Mel of 32,500:1:54.
