I recently read a 2008 study about people with diabetes and hypertension who were treated with a combination of arginine and n acetyl cysteine (nac), two commonly available substances at online vitamin sites.
http://care.diabetesjournals.org/content/31/5/940.long
At the dosages used in this study, arginine and nac have a fairly good safety profile and from the study results, they not only lowered blood pressure, but produced side effects that were also positive such as lowering ldl cholesterol while raising hdl cholesterol (the good one) and lowering levels of adhesion molecules vcam1 and icam1. It also lowered high sensitivity crp, a common marker of inflammation in the body. Add in the antiatherosclerotic effects and it seems like a good combination so I started taking them two weeks ago. One drawback to this study is the small number of participants, but the results were striking enough to make me want to try it.
Nac by itself has hundreds of studies suggesting it has many health benefits in humans, some related to its efficacy as a potent antioxidant.
I just took my blood pressure reading and it was 123/83. I am taking more than what was used in the study, at least initially and plan to go down to the study dose after a month or so.
I take 600mg of nac with 1 gram of arginine, three times per day for a total of 1.8 grams of nac and 3 grams of arginine per day.

Lisinipril @ 20mg daily has been very beneficial for me (also an unresponder). I'm not a big proponent of pharms but if the cost is not too high and the negative side effects few, "go-for-it".

It seems like wherever I go, I run into people with hypertension/high blood pressure, so it must be fairly prevalent. Given that high fructose corn syrup and high levels of table salt in processed foods are the norm in many peoples diets, I can certainly see why high blood pressure would be a common problem. Btw, I read another 2010 rat study that suggested that the nac/arginine combo might also help offset the known hypertensive effects of a high fructose high salt diet. It was only a rat study and those don't always translate directly into human equivalency, but it is promising and worth further study in humans.

In further reading it seems like citrulline, a precursor of arginine might also be effective with nac or even with nac arginine. The safety profile of these three along with their other health benefits seems like it may be a good first line hypertensive therapy approach before trying the prescription route if people are so inclined.
To answer your question, I continued with what I was already taking as I was taking things like the potassium, magnesium, zinc, vitamin d, multi-vitamin and vitamin b complex for other health benefits other than high blood pressure reduction so I didn't want to lose out on those potential health benefits, plus there is the possibility that those supplements may have been partially controlling my blood pressure already.
I hope others are able to derive benefit from this reasonably priced and readilly available combo(nac/arginine) with the good safety profile! It is amazing to me that there were no direct follow up studies after that promising one in 2008. I guess if it isn't patentable, then funding may be hard to come by.

I also dropped my dose down to just twice a day instead of three times per day, so I am currently taking 600mg of nac with 1 gram of arginine two times per day for a total of 1, 200mg of nac and 2 grams of arginine per day which is fairly close to the dosage used in that 2008 study.

NAC is noted for its glutathione increasing potential and is itself a free radical scavenger as well as an anti-inflammatory, capable of inhibiting inflammatory cytokines and mediators like, il-1, il-6, and tnf-alpha so it maybe more than just helping to increase glutathione levels.
NAC is fairly impressive as is its safety profile. The combination with arginine seems to be very impressive. I hope it continues to work!

Evidently the human body or at least a compromised body cannot properly make the conversion of sulphur containing foods to the acetylated form of Cysteine, making this supplement quite important. I have read that NAC is first line defense in emergency care for many cases of overdose or poisonings. There are more and more studies proving many benefits of Arginine.

This more recent rodent study may give a clue why:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3877599/
Apparently NAC may help prevent high blood pressure from getting started in the first place. It's only a rodent study and that does not mean it will be the same for humans, but NAC and arginine have very good safety profiles with generally positive side effects as compared to the negatives of many BP prescriptions. There are many studies on the benefits of NAC.
It's actually pretty sad that after the original study from May of 2008
http://care.diabetesjournals.org/content/31/5/940.long
that produced such impressive results and led me to try arginine / NAC in the first place, there were no follow on studies to help confirm the efficacy of this cheap and safe combination in larger groups. If it was patentable, I'm sure it would have been a different story though.
Obviously people should not attempt this combination without their doctor's approval and supervision as high blood pressure can be dangerous and sometimes deadly.
I still use all three for different things, but not everyday anymore . The lysine was needed at the time to keep my arginine / lysine ratio in balance as I felt I was getting more frequent colds than what is normal for me when using just the arginine and NAC. Overall I would rate this combination of natural supplements very high at a level somewhat similar to the borax remedy that is frequently discussed here.

I have been taking NAC for over 2 years and noticed my blood pressure had decreased (120/76). Prior, my pressure was 140/80 even on medication. I started taking meds for Hypertension when I was 35 years old. I am now 61 and have the best blood/lipid profile ive ever had in my life. My blood pressure is the lowest I've ever had with or without meds.
I attribute this to my experimentation with NAC, Turmeric etc. My doctor did not have a clue
