High quality, reasonable price. L-Arginine has benefits for muscles, energy production, reproductive system because it enhances blood flow, perfect for detox. Good size, no taste, easy to swallow. I am taking 1500mg between meals twice a day as a part of anti candida protocol. If you want to build muscles, this supplement is must-have along with healthy diet and workout.

Arginine supports the production of Nitric Oxide gas (NO) inside of our blood vessels and NO relaxes the muscle of the arteries subsequently dilating them and reducing the blood pressure inside. According to the natural integrated and holistic medical science, it's best to combine L-Arginine with L-Citrulline (another Amino Acid) in the ratio 4 to 1 like taking 2000mg of L-Arginine with 500mg of L-Citrulline. It's much better solution than to take Big Pharma blood pressure meds having dangerous side effects. I use to have elevated BP in the range of 160/90 and even after taking prescription drugs, my BP was still around 145/85. Since I started to take L-Arginine (about 2000mg) my BP has dropped to 125/72, however, it would take a little time - about 2-3 weeks or even more. ALSO ,Huge pills so take caution. Other then that I'm rating them 5 stars because they help me last longer in bed and it makes me harder. I've taken Viagra (probably generic) and these worked better. I'll be buying more when I run out

I find a lot of people who don't eat well and are often running at their limits. This vitamin has everything they need to improve their health, immunity, quality of life, well-being, mood. It's an excellent supplement with noticeable improvements in strength and energy. I find it invaluable for my everyday routine!

Been an iHerb customer for 10 years. Had heart surgery 8 years ago and has an auto-immune disease. One of my top high quality supplements. 👍🏻

I decided to leave a review. I saw on the Internet this product. I was looking for it for a long time and now I found it. I didn't expect, but that's exactly it. I don’t regret it.

I take L-arginine because I have hypothyroidism. I took it on my own, and also together with Nac and Inosiol, with whom I work in synergy. I am happy because for me this is probably one of the best amino acids for stimulating follicles and fast hair growth. I also go to the gym and it helps me keep my muscles overloaded after the gym. I always keep it in stock !!! I recommend !!!

Excellent quality. Convenient packaging. I order not the first time. L-arginine is an essential amino acid in most cases. In an adult and healthy person, arginine can be produced by the body. At the same time, for children and adolescents, the elderly and sick people, this amino acid is really indispensable, since the level of its synthesis is often insufficient. The biosynthesis of arginine is carried out from citrulline under the action of arginine succinate synthase and arginine succinate lyase.

I am mostly vegetarian and L-arginine is an amino acid naturally found in red meat, poultry, fish, and dairy, therefore a wonderful supplement for my lifestyle. I sense better circulation and wellbeing when taking it. I find Now Foods to be a company that provides quality at an affordable price for this product. I take 2 caps per day with a meal.

This L-arginine supplement has helped me massively in reducing my blood pressure. Just like almost all now foods products, the quality is great. The benefits from its ingredients are incredible and can be noticed after measuring my blood pressure. I don't use it for training like some athletes do with their workouts and fitness, but I use it as part of my regular diet. Capsule size is reasonable and has no taste which is also good.

Perfect easy to swallow size capsule. Keeps me fit and energetic. Best quality product I have found. Just the right dose and plenty in the package. Benefit to stay heart healthy. The veg capsules make this a good supplement choice for animal friendly consumers. Keeps my workouts going strong. Great addition to a healthy diet.
