Guest guest Posted January 5, 2006 Report Share Posted January 5, 2006 L-arginine together with Gingko Biloba may reduce some of the SSRI-induced sexual side-effects. I for one use it. So it was with some unease that I read the following article about possible deaths from arginine supplementation. The people in question are cardiac patients which make them quite a special subgroup, it´s a fairly small study so it could be a statistical fluke and it doesn´t state the dose having been used, but I ask whether it could be a cause for concern for those of us using the substance? Perhaps it could be a case for being careful not to use a larger dose than necessary. I take 2,5 mg per day since I started recently, just because that was recommended on the bottle. How much do people on this list currently take - what dose have you found to be of use? I recall seeing from 1 mg to 8 mg per day. Ulf " Tue Jan 3, 4:03 PM ET CHICAGO (Reuters) - Heart attack patients should avoid the dietary supplement L-arginine based on a study that was scuttled after six volunteers taking the over-the-counter supplement died, researchers said on Tuesday. The study of 153 people who had had heart attacks and continued to have symptoms of heart disease found no benefit from taking the supplement sometimes advertised as having the potential to reduce vascular stiffness. L-arginine is also sometimes touted as a treatment for hypertension, angina, heart failure and sexual dysfunction. After six months of a planned two-year study, Dr. Schulman of s Hopkins Medical Institutions in Baltimore concluded that the supplement did not reduce vascular stiffness, nor did it improve the heart's ability to pump blood. " To the contrary, we noted a possible increased risk of death in older patients after (heart attack) while taking L-arginine compared with those taking a placebo, leading to the early termination of the study, " Schulman wrote in the Journal of the American Medical Association.

Guest guest Posted January 5, 2006 Report Share Posted January 5, 2006 This is a surprising result. L-arginine is supposed to reduce blood pressure by inducing nitric oxide synthesis, and there's quite a bit of evidence that it does just that. Why it would increase death rate in heart attack survivors is very unclear. Note that of the 6 deaths, 3 were of unspecified causes. I think there needs to be much more follow up to determine what's going on. BTW, dose was 9 grams per day. I presume you mean you're taking 2.5 grams per day, not 2.5 mg?

Vornan Vernon, Yes, of course, it´s 2.5 grams per day I´m taking. Together with 100 mg of Gingko, it has a prosexual effect for me and I´m thankful for that. I agree, there is no reason to be unduly alarmed at the results from the arginine supplementation. I am experimenting, though, by reducing the dose to one gram to see if the effect holds. Are you still on arginine and what dose are you on? Ulf Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 6, 2006 Report Share Posted January 6, 2006 Hi Ulf, I take anything from 1 - 6 grams per day, sometimes a bit more. It varies depending on whether I'm gonna work out or not, stuff like that. I too am not really worried about this study.

Guest guest Posted January 6, 2006 Report Share Posted January 6, 2006 Here is a post from another board I'm on that confirms my suspicions that the arginine study was bogus. Vornan Below is Bill Sardi's analysis of the nonsensical conclusion that came out that made arginine look bad for cardio patients. We are all under attack by the drug companies who are paying to create bad studies that make nutrients look bad. They are doing this, just as Karl Rove does it for Bush, by outthinking the public and the medical people who DO NOT actually do in-depth analysis, but rely on a scan of a headline from a source they " trust. " We are under attack -- the attack on our long-term health. We are like cattle that they feed on. They don't want us to be so healthy we don't need to take drugs. They want to maintain us in a state where we need doctors and drugs. We will continue to see nonsensical studies that would seek to undermine our confidence in safe, beneficial non-toxic nutrients, and herbs. Watch for them and be wary of them. Mooney www.michaelmooney.net www.medibolics.com *********************************************** Should The Public Be Wary of Arginine Supplements 2006-01-05 - Knowledge of Health, Inc. By Bill Sardi The headline report at WebMD said " Don't take L-arginine for Heart Attack. " I don't know of a person undergoing a heart attack who would think of reaching for arginine pills, let alone be able to swallow 9 grams of this amino acid while attempting to gasp for breath and deal with the crushing chest pain. But that's what the headline said. It sounds like somebody is attempting to scare the public away from arginine pills. I Wonder why? Arginine has been marching towards greater acceptance for treatment of a variety of cardiovascular disorders in recent published studies. The Journal of Nutrition suggests human studies begin using arginine among adults with high blood pressure, since arginine is required to produce nitric oxide, a transient gas that dilates (widens) blood vessels and helps to control blood pressure. [Journal Nutrition 134: 2807-11S, 2004] But the January 4 issue of the Journal of the American Medical Association (JAMA) put a halt to the enthusiasm for arginine with the announcement that supplementation resulted in the deaths of six patients versus none in an un-supplemented group. [The Journal of the American Medical Association, January 4, 295: 58-64, 2006] Contrary reports To the contrary, when researchers in Poland provided 3000 milligrams of arginine, 3 times a day for 30 days, to people following the onset of symptoms of a heart attack, 24% of patients given arginine experienced shock, pulmonary edema or a second heart attack, versus 27% in the untreated group. The researchers report that " no serious adverse events were observed during arginine supplementation. " [Kardiology Poland 62: 421-27, 2005] Of course, this study wasn't heralded in news reports. Statistically it could be said the Polish doctors demonstrated a 13% reduction in adverse cardiac events following a heart attack. Let's take a look at another recent study. When arginine is infused into patients with poor circulation during coronary artery bypass graft surgery, 18 of 20 patients had their cardiac rhythm return to normal spontaneously versus only 4 of 20 untreated patients who had to undergo electric shock (defibrillation) to get their heart rhythm to return again. [international Journal Cardiology 97: 93-100, 2004] Before we go any further, readers need to understand how arginine works. The body must control the internal diameter of the arteries. Physical activity increases the demand for oxygen, increases the heart rate, and could raise blood pressure, but the blood vessels compensate by dilating (widening). The blood vessels cannot dilate properly without sufficient amount of arginine, an amino acid, which is required for production of a transient gas called nitric oxide. Nitroglycerine pills also generate nitric oxide to dilate blood vessels. [Cellular Molecular Biology 51: 307-20, 2005] Bottom line, arginine is essential for human health. Confusion So is arginine good or bad? Actually, patients with coronary artery disease who experience mortal outcomes are more likely to have high levels of an inhibitor of nitric oxide, dimethylarginine, which is a by-product of arginine. [Circulation Research 97: 53-59e, 2005] But here's the confusing part. When animals that have been genetically engineered so that they don't produce nitric oxide are subjected to a heart attack, they experience a better outcome. The provision of arginine worsens their condition. The decrease in the heart pumping action (ejection fraction) and increase and the enlarged size of the left ventricle of the heart are less severe after a heart attack in mice that cannot produce nitric oxide. In the post-heart attack period, a shortage of nitric oxide improves heart function. [American Journal Physiological Heart Circulation Physiology 289: H2616-23, 2005] But of course, this is an abnormal condition where the normal control of nitric oxide via arginine has been removed. So it doesn't apply to humans undergoing a heart attack. The body attempts to product just the right amount of nitric oxide, not too much, not too little, and more when needed. A recent study shows that 9000 mg of arginine given to patients with coronary artery disease did not increase levels of nitric oxide bioavailability. [Circulation 101: 2160-64, 2000] This is because the body produces it upon demand, such as with increased heart rate, etc. A person can pour all the arginine they want down their throat, it will only produce more arginine if the person is deficient in this amino acid. Which is what the researchers retrospectively now surmise who wrote the Journal of the American Medical Association report. The patients in the JAMA study were sufficient in arginine. The missing information But there are some facts missing that the public needs to be aware of. The patients in the American Medical Association report were being given other medications, aspirin (which depletes folic acid and vitamin C), a beta blocker (which slows the heart rate), an ACE inhibitor (to control blood pressure via artery dilation), and a statin cholesterol-lowering drug that depletes the body of coenzyme Q10, an antioxidant needed for heart muscle energy. It's no wonder arginine had no effect upon the ejection fraction (the measure of blood pumped out of the ventricles of the heart). The patient's were on three drugs that impair heart function! The production of nitric oxide is countered and controlled by dimethylarginine. [Hepatology 42: 1255-57, 2005] Researchers in Korea found higher levels of dimethylarginine after heart attacks, which is associated with cardiac risks. They also attempted to measure whether dimethylarginine, a by-product or arginine, which inhibits the overproduction of arginine, is influenced by medications (like the one's used in the JAMA study), but the numbers of patients taking various medications were too small to develop any conclusions. [American Journal Cardiology 95: 729-33, 2005] Proper conclusion The conclusion of the study published in the Journal of the American Medical Association should have been, if a person has experienced a heart attack, and they are on all the deleterious standard medications which are not essential for human health, and which deplete the body of nutrients essential for cardiovascular health, then maybe they shouldn't take arginine, because there may be some kind of incompatibility. However, it would have been nice to see what arginine could have done all by itself, without the drugs to interfere. Arginine in Russian experiment Before the public is frightened away from arginine, let's go to Russia, where researchers used arginine in an animal experiment. Russian doctors experimentally induced heart attacks in animals. When a heart attack was induced and arginine was administered, cardiac output, blood pressure and heart rate were stabilized and 80% of the animals survived in the arginine group versus 33% in the non-arginine group. [bulletin Experimental Biology Medicine 139: 384-87, 2005] Arginine in France So, finally, researchers in France were looking for an agent that would augment and enhance nitric oxide production when taking statin cholesterol-lowering drugs. Researchers in Paris demonstrated in animals that the combination of arginine with a statin cholesterol-lowering drug significantly " hinders the spread of arterial plaques " over the use of statin drugs alone and " opens a new era of therapeutic strategy. " [ls Biol Clin 63:443-55, 2005] It seems these days, any time a nutrient or herbal agent appears it could replace more expensive and problematic drugs, a news headline soon appears slamming the nutrient or herb. I'm wondering if the public is becoming suspicious of these news reports and the pseudo-science that is behind them? - Bill Sardi Copyright 2006 Knowledge of Health, Inc.

Guest guest Posted January 6, 2006 Report Share Posted January 6, 2006 I hope all this stuff is exposed in michael moores next film. Some people have recovered Mike and some people improve with certain treatments its all very complicated.When asked by my doctor if i was depressed i simply said " no " . If i didnt i knew the next words out of his mouth would be blaming sexual dysfunction on depression instead the pills he gave me. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 8, 2006 Report Share Posted January 8, 2006 I´m sorry if I caused any unnecessary commotion by quoting that arginine supplementation study on cardiac patients. However, for my own part it was good writing about it because seeing that subsequent analyis by Sardi, displayed on this list, certainly helped put my mind to rest about arginine. Vornan, you mentioned varying doses of arginine. Why would it vary depending on whether you exercise? (I assume you mean exercise by " working out " , and not sexual activity - the latter I would understand if it were the cause of a varying dose!). Before I started arginine/biloba, Viagra/Cialis was of some help, but I´m uncertain whether they help now. Perhaps they are not additive to arginine because they target a similar pathway.

Guest guest Posted January 8, 2006 Report Share Posted January 8, 2006 Yes, by " working out: I mean exercise :-) If only sex was a workout! Right now it much more of a cuddling/spooning type of thing. But seriously, I do increase the dosage of arginine on the days I lift weights. Say a few grams about an hour before working out. Viagra or Cialis could be additive to arginine because although they both increase NO, they do it through a different mechanism. I'm not sure I would recommend it though.

Guest guest Posted January 10, 2006 Report Share Posted January 10, 2006 Hi Ulf, Techically speaking viagra et al. don't increase NO levels. Nitric oxide (NO) activates the enzyme guanylate cyclase which results in increased levels of cGMP, resulting in increased inflow of blood and an erection. Viagra et al. work by blocking the breakdown of cGMP (by inhibiting PDE5, which is responsible for degradation of cGMP in the penis). So viagra doesn't actually increase levels of NO, but rather increases erection strength further downstream of the pathway. In theory combining arginine with viagra would work because the arginine would generate more NO leading to more cGMP, and then the viagra would block the breakdown of the cGMP. Though I'd be wary of priapism from overloading the system. It's not something I would try myself.

Guest guest Posted January 10, 2006 Report Share Posted January 10, 2006 ....and I think arginine would always be the safer option of the two because it is a natural amino acid, whereas viagra is obviously something that doesn't normally exist in the body. -- In SSRIsex , " v0rnan19 " <vornan19@g...> wrote: > > Hi Ulf, > > Techically speaking viagra et al. don't increase NO levels. > > Nitric oxide (NO) activates the enzyme guanylate cyclase which > results in increased levels of cGMP, resulting in increased inflow > of blood and an erection. > > Viagra et al. work by blocking the breakdown of cGMP (by inhibiting > PDE5, which is responsible for degradation of cGMP in the penis).
