NutricostL-Arginine (250 Grams) - Pure L-Arginine Powder - 5000mg Per Serving; 50 Servings

I just want to address some of the people who say that this tastes "disgusting"! I bought this because the brand I normally use was not available. I use L-Arginine with my chocolate flavored grass fed whey protein powder and creatine. I blend it all with either whole milk or water. This L-Arginine cannot even be detected where actually my other L-Arginine brand does have a very slight, noticeable chemical taste but nothing "horrible" or "nasty"! You have to mix this in a protein drink and not just stir it in water! Even if you did that it still doesn't have that bad of a taste at all! And, believe me, I'm an expert when it comes to protein powders and supplements like this for many years as a weight lifter and fitness/exercise enthusiast! This is good stuff! I can't taste it at all! So, those people who said how disgusting it is, you must be hypersensitive or used to drinking kool-aid or something! I can also tell that my blood flow and energy level is optimal about a half hour after drinking it.

If you are taking L-Arginine for your heart health or for body building, this is the stuff you want. It has no additives and no hydrochloride (.HCl).If you are being scared away by the bad reviews about taste or dissolving problems, don't be. If it didn't have a bad taste, which is not anywhere near as bad as some are claiming, then it would not be pure L-Arginine - the pure stuff has a slightly fishy taste. If it dissolved quickly, it would be modified with with hydrochloride (some claim this inhibits your body's ability to use it properly). Both problems are extremely easy to fix. Just add citric acid. If you want to get that naturally, use lemon juice. Otherwise, buy a bag of food grade citric acid here on Amazon. I add about the same amount of citric acid as L-Arginine, then add about 8oz of water. It will take about 60 seconds to fully dissolve, and will end up water clear. If you don't add enough, it will still have a fishy taste. If you add a bit too much it will be sour like lemonade mix (which is the way I like it). Add exactly the right amount and it won't have much of any taste at all. Best of all, citric acid is very good for you (google "citric acid benefits"). There are some reviews speculating that the addition of citric acid might damage the L-Arginine. Don't believe them. They are remembering simple physical chemistry from high school. This is actually organic chemistry - yup, the big, ugly, complex kind some of us took in college. Chemically weak acids like citric acid will not harm L-Arginine at all.Bottom line, this is the stuff you want. It's pure L-Arginine, and the cost per gram is the best you are likely to find.Cheers.

I bought this to help reduce hypertension and improve circulation. This stuff works very well. It really helps with post workout recovery and has even helped to reduce fatigue. Once scoop dissolves in water very quickly and easily with stirring. However, the flavor of this stuff is absolutely disgusting. It tastes like the ocean smells. Fortunately, it doesn't have a lingering after taste. If I wasn't able to feel the immediate positive effects of using this stuff, I would have opted for a refund. I will use it until it's gone since it works, but I'm going to try another brand to see if L-Arginine is simply a disgustingly flavored amino acid, or if it's just this brand.

Do yourself a favor and buy powdered citric acid when you purchase this and mix it in a 3:1 ratio (arginine:citric acid). Add this to water, stir until clear, add citric acid, stir until clear, enjoy.This supplement is exactly what I was looking for when considering options for L-arginine. Powdered form, 5g/serving, includes scoop. Perfect. Until I tasted it by itself in water. Holy expired year old fishy latex, batman! Words alone cannot describe how horrid the taste was. Every night was a battle against my stomach to keep this stuff down. Nothing I tried could mask the taste UNTIL I read reviews pointing towards citric acid and holy sweet 8lbs 4oz baby Jesus did that change my entire outlook on this supplement. With the right amount of citric acid, this supplement is actually a joy to take. The acidity in the citric acid counters the alkaline in the arginine and makes it palatable. Don't try this without citric acid.-1 star because of taste, but that's easily fixed with a dash of citric acid. Everything else is perfect.

I bought the 500 grams for $19.95. When you consider the amount that you get for the price, it's a great value (especially when compared to pills). There's a small scooper inside that gives you 5 grams per scoop. I lift weights, and I've noticed that my arms are even more vascular ("veiny") than they were before. My blood pressure has also decreased by a few points (though I can't guarantee that this is the cause).I've heard a lot of people complain about the taste, so here's my experience. When I first got it, I mixed it with juice or protein powder. It tasted horrible. It completely ruined and overpowered the taste of my drinks so that they no longer tasted like what they were. After about 2 weeks, I was hating the fact that I had over 400 servings left and had made up my mind that I was going back to the pills. I got tired of wasting my juice, so I decided to try chugging it down in water. Wow! Somehow, it tastes MUCH better with just water. It tastes like baking soda. If you mix it with water and chug it down, then it's not bad at all. Now, I don't mind drinking it, and I've actually started drinking it twice on some days. Now, I'll definitely buy this again and have no plans to go back to pills. I highly recommend drinking it with water. For some reason, mixing it with juice or protein powder strengthens the taste and makes it disgusting.Since it seems to work for me, is a great value and tastes ok with water, I'm giving it 5 stars.
