helps stimulate energy levels along with other amino acids.

I'm an African American male in my low 50s and woke up one day to find I had elevated BP. An estimated 40% of blacks suffer from high BP and in my search for a solution, I learned about perfusia it in Kowalski's book, "The Blood Pressure Cure," which is itself a great book which I also recommend. He gives the science behind BP control and what we know about alternative meds. In fact, an M.D., Kowlaski does not reject pharmaceuticals but says they should be the last resort. I agree with him. Remember the enemy is not pharmaceuticals but high BP. Kowalski gives a raft of safe, "natural" supplements backed by research to try. Thus, I began to systematically explore them one by one about 8 months ago. I figured something had to work. When I began experimenting with perfusia my BP was 135/92 at home. This may not sound very high, in fact, it is borderline. But keep in mind this was the median BP which means half were above this figure and half below. After using perfusia for about four months, I took after 25 BP measurements over two weeks at home and I found my median BP had dropped to 121/79. I had also began exercising regularly (I got a gym membership and walked for one hour five days a week); I practiced slow breathing (almost everyday for 20 min); and I increased my K:Na (potassium-sodium) ratio to 5:1, again all per Kowalkski. While I cannot say with 100% certainty that perfusia is the sole explanation for my BP drop, the fact is that I had been exercising and slow breathing prior to perfusia with no positive results. Perhaps perfusia works optimally with these other things. I don't know. In any case, they are my insurance policy, kind of a layered strategy. What I find interesting is that after some research many of the things in Kowalski's book work by increasing NO (nitrous oxide) in the endothelium of the blood vessels which relaxes them. Exercise, increasing K, polyphenols in vegetables, etc. do this. L-arginine which is the main ingredient of perfusia is an NO precursor. What makes perfusia different is that it is time-released. Apparently, ordinary L-arginine is metabolized very quickly to be of any practical use. Thus, the claim is you can't go out and use any L-argine supplement, although I don't know if this is really the case since I haven't tried any other L-arginine supplement. Perhaps most importantly, I seem to have had no side effects (knock, knock). Finally, the cost of this product is not cheap. However, cost is probably on par with pharmaceutical BP meds which are infamous for their negative side-effects. They are horrible. You can do the research and see for yourself what others are saying and what the data shows. So for me, perfusia is a bargin, all things considered.

This is a very simple purchase. And I’ve only been using this for a few days.

Thorne is a quality product. They don’t sell useless junk vitamins that you can get off the shelves of local retailers.

I have purchased several L-arginine supplements, and so far this is the one that has worked best for me. It is perfect.

I like the quality of this product but it is rather expensive. Capsules are easy to swallow. Needs to be taken on an empty stomach for best results, as do most amino acids.

BOTTLE ALMOST EMPTY...NO CHANGE AT ALL
