I have moderately high blood pressure and this product is helping to keep it under control. Its helpful in lowering both numbers.

I'm taking L Arginine along with NAC supplement, and it has reduced my blood pressure from 160/90 to 123/60 (within a month). I am very pleased!

I have been taking L-Arginine 500MG for a very long time. My previous orders were from another company that is very slow with delivery. It seems to help with circulation. First dose I took, I could feel blood rushing into my feet. I can't say this will happen for everyone, but this is my results. I plan to continue it indefinitely. I received my order promptly. Good service from this company. Thank you!

I take it before bed and, though it's not touted as a sleep aid, it really helps me get deeper, more relaxed sleep. My spouse has had severe leg cramps at night with little found for relief over the years. He tried these before bed and...no more cramps.

We have tried many brands and this compares just as well to many others. There is only 500mg but you do get 250 capsules in the bottle. As a dietary supplement take one capsule up to three times daily with a meal. For best results I was advised by my own personal health care professional (make sure you ask your own) to take 20-30 minutes before a meal with an 8oz glass of water. There is no bad aftertaste or negative side affects that I have experienced. This product is often used to help convert food to energy providing support for endurance exercise. This dietary supplement is made in the USA. Do read the ingredients list as there is gelatin, magnesium stearate and silica as added ingredients. However, there are no added flavors, sweeteners, preservatives, sugar, starch, sodium, milk, wheat, yeast or fish.<br /><br />L-Arginine is an essential amino acid, meaning our bodies need it. You get it from red meat, poultry, fish, or dairy products but if you are a vegetarian or vegan, you probably will not get enough arginine in your diet. This amino acid is also for heart health and especially as a supplement for those with congestive heart failure. My husband is a cyclist, he also had a triple bypass a year and a half ago and I am a newbie at it. We go for hours at a time on our road bikes and my husband competes in cycling races. It can also be great for boosting energy at other times and alleviates our age related side effects and chronic fatigue. My husband at 53 especially finds this a wonderful product. For him taking L- Arginine really helps him push it more since it gives you more energy. My rides are strong and steady, without me fading. I received this product at a discount in exchange for a review of my honest and unbiased opinion.

My diabetes doctor recommended L-Arginine 500-1000 mg because I am starting to have circulation issues. He says this will help; I'm hopeful that it will!
