Life Extension L-Arginine Caps 700 MG 200 Capsules
L-arginine is involved in many body activities, including ammonia detoxification, hormone secretion and immune modulation. Arginine is also well known as a precursor of nitric oxide (NO), a component that delivers messages between body cells and partly controls the blood circulation. As a result, when nitric oxide is synthesised by L-arginine, the arterial system is able to retain its youthful elasticity. At the same time, the immune system becomes stronger and Arginine also helps in maintaining your bones and tissues healthy. L-ornithine, a metabolite of arginine may contribute for the latter purpose too. Some studies suggest that arginine and ornithine stimulate growth hormone (GH) evidenced by an increase in muscle strength during intense workouts. Other studies show the same effect for Ornithine alone. Some studies confirm that a combination of ornithine with acetyl-L-carnitine enhanced the GH release, while a low dose of the given combination is insignificant. The minimum dose required seems to be 5-9 grams.

I have a very positive experience using Life Extension, L-Arginine Caps. I am satisfied with the effect , it accelerates the dilation of blood vessels, which also helps with erection problems. In addition, it has an excellent effect on increasing muscle mass. Such an effect is most pronounced during the night, ie. in the first hours of sleep, which is why I recommend using it just before bedtime. It also has a positive effect on melting fat deposits, but this is only possible if the diet and increased physical activity are regulated. For weight loss, a supplement alone is not enough.
A chiropractor/nutritionist held a session on l-Arginine several years ago which I attended. One of the things addressed was that it's good for the heart. So I started taking l-Arginine and take if every day. I really like the Life Extension products; not a lot of extra fillers and things in them.
Facilitates immune function and increases nitric oxide and assists in wound healing. I like the big flacon with 200 capsules. Take outside meals. Very good for male health.
+ Ve1.Good product2. no after taste3. nice quantity_ Ve1. Costly2. no. of capsules are more for good dose3. strange smellDelivery On time,
