There are plans to test butyrate supplements as well, given preclinical evidence that butyrate reduces demyelination and enhances remyelination in the CNS
One factor that potentiates the impact of these amino acids on circulating levels of NO is the presence of a sulfur-containing compound like glutathione or N-acetylcysteine (NAC), to which NO readily binds.[40] Glutathione, which contains a thiol (a sulfur-containing functional group), binds NO, forming S-nitrosoglutathione.[41] S-nitrosoglutathione transports and circulates NO and has a half-life of tens of minutes or hours, which compares to the half-life of NO, which about is one to two milliseconds.[42] S-nitrosoglutathione also dilates blood vessels,[43] with studies suggesting it is just as vasoactive as NO.[44],[45],[46] Interestingly, levels of glutathione have also been shown to be significantly lower in patients with ED than in healthy controls, with those having both diabetes and ED having the lowest glutathione levels of all subgroups being assessed.[47] Indeed, a combination of L-arginine (1,200 mg/day) with NAC (600 mg twice daily) has been shown to significantly reduce blood pressure, simultaneously improving various markers of oxidative stress and inflammation.[48] In animals, the combination of L-citrulline and glutathione (at a 10:1 ratio) was shown to have a greater effect on nitrate and nitrite levels than L-citrulline alone.[49] Levels of nitrite and nitrate were also shown to be highest 30 minutes post-exercise in humans who were given a combination of L-citrulline and glutathione (also a 10:1 ratio) compared to placebo and either substance as a monotherapy
The inclusion of a greater number of antigenic subunits may lead to unfavorable three-dimensional structures, which could result in the loss of critical conformational epitopes
