Awesomely cheap, and superb in quality. These guys threw so much inside this. The ingredients in these is assured by their brand name. They have been making these for a long time. It wins over most arginine amino acids by sheer quantities. Size of the capsule is ok and these are cost efficient, which is a big plus. No foul taste or smell.

I bought this as a booster for my workout and it sure helps to increase my stamina.Being in my late 40s so my stamina is going downhill so I have been recommended to take L-Alginine. This is one of the lower price available so I tried it. It sure works after taking this for a few days. This is my third time to buy this product. I take 2 pills per day and that is enough for me.

i bought this product for my son as advised by his pediatric doctor in order to get taller during his teenage. he is taking it before sleep and after exercise. and every other day he is taking Zinc tablets. It is the cheapest product among tablets & capsules. L-arginine is considered a conditionally essential amino acid, since it is produced in sufficient quantities only in a young and healthy body. However, L-arginine protects blood vessels from the accumulation of sclerotic plaques, lowers blood pressure, improves cerebral circulation, inhibits inflammation, increases efficiency, and improves mood. L-arginine is also essential for weight loss and muscle building.

It always works well for me! Great quality as always! I’m buying it not a first time. The main ingredient is L-Arginine is a quite good for men health and also for mental health. I need to improve both. Very good value for money! Great size! Will last longer! 4 times cheaper than in Holland and Barrett in the U.K. ! Taste as usual 🤤 I also go to the gym so it’s perfect for fitness body and long workout 🏋️♀️ also it’s very essential for healthy diet as a natural supplement for our body. I usually take one tablet in the morning or before the training. Definitely will buy it again!
There is some difference when consuming this for first couple of weeks, but after that, seems insignificant. There's increase blood circulation experienced when needed and better energy level. I can also sense my muscles seems to be in better shape haha! However, seems short lived for some reason. Maybe it's my body reaction to it. Packaging wise was good and quality looks premium. Tablets are slightly bigger, some would find it harder to swallow.
I got this supplement after I read that L-arginine may benefit those with diabetes by improving glucose metabolism and insulin sensitivity. I am still trying it out and will update my review accordingly. The package looks clean and suitable for this product. Everything arrived in perfect condition.
