Arginine is an amino acid found in all proteins that promotes preservation of lean body mass so you lose fat and not muscle. We have found that it contributes to a feeling of satisfaction in hunger. (See What does arginine do?)

It is best to take it as a dietary supplement roughly 30 minutes before physical workout. Alternatively, it should be ingested on a relatively empty stomach either late in the evening or early in the morning. See similar questions...

As with most nutrients, I recommend taking breaks from use. In the case of arginine, it appears to be safe to take for extended periods as long as the dose is less than 2 grams a day. See similar questions...

Dear Dr. Sahelian, I appreciate the sound advice and education that you provide. I have one question and I understand that by responding you are NOT in any manner obviating the need for me to get direct advice from my own physician. More than 25 years ago I had bypass surgery. I have NOT had a recent heart attack. However, I do have aortic stenosis. I have been taking 500 mg of L-arginine twice per day. Is the L Arginine harmful, maybe helpful or irrelevant? Thank you and keep up the good work. See similar questions...

I have not come across any studies that indicate arginine ornithine lysine together help promote health. I don't see any clinical reason why l arginine would cause or prevent a tumor. As to arginine cream, I can't imagine enough being absorbed to have a clinical effect. See similar questions...

We really can't say since each person responds differently and we have no idea of your health condition. As a rule, Passion Rx is potent by itself and there is little need to take any other supplements the same day. These are excellent questions and at this time I don't know the precise answers to your questions but will search for research that explores the supplement arginine nitric oxide connection. I am not impressed with arginine for erection problems. See similar questions...

A byproduct of the arginine intake is an increased energy which allows you to get more exercise which increases endurance. Arginine also increases the production of your natural Human Growth Hormone. See similar questions...

The disturbances leading to cancer cachexia remain to be unraveled. Preliminary evidence suggests that arginine availability in cancer is reduced. However, no valid data are available on plasma arginine concentrations in cancer patients. Objective: We aimed to determine whether there is evidence for disturbed arginine metabolism in cancer.

The amino acid L-arginine does NOT cause transfer of herpes among individuals, and will NOT promote herpes in someone who is not infected. In addition, scientific studies do NOT support the "street tale" that dietary intake of L-arginine may be involved in activating herpes in those who are infected. See similar questions...

It depends on how much you plan to take. If your dose is 1 to 5 g, the capsule works. If you plan to take more than 5 grams of arginine, then the powder is more efficient. See similar questions...

Q. I have followed your career since my wife and I heard you at a book review at the La Quinta Hotel some six or eight years ago. I would like to call your attention to a problem I had recently with taking l arginine in quantitity (6 g per day) over several months, I came down with rosacea, which cleared up when I stopped taking it and with standard treatment by a dermatologist.

ArginMax is formulated to allow these ingredients to work in concert, resulting in a synergistic effect that exceeds the benefits possible with any single one of these ingredients, and at a lower dose of the individual ingredients. In addition, the Daily Wellness Company formulates ArginMax using only highly standardized grades of ingredients. There is sound scientific basis for the mechanisms of action of ArginMax as it relates to the Nitric Oxide pathway. See similar questions...

Niteworks? is a patent-pending formula that combines a unique blend of L-Arginine and L-Citrulline. Through Dr. Ignarro's work, we learned that L-Citrulline (a virtually unknown amino acid) in combination with significant amounts of L-Arginine will essentially recycle Nitric Oxide, thus allowing longer action of this heart-protecting compound. D-Alpha Tocopherols are fatsoluble antioxidants that neutralize free radicals to help sustain Nitric-Oxide production in the body. See similar questions...
