  Scientific explanation of taste and more

  I give this 5 stars, trusting that the powder is indeed pure L-arginine. It does indeed taste fishy (mixed into water). I did some internet research and refreshed basic biochemistry of amino acids: of the 20 amino acids, arginine is among the positively charged and has an alkaline pH, and that's why it tastes fishy and "amine-like." The addition of acid to the arginine solution will neutralize the pH, at which point it will be mostly tasteless--thus the reviews that mention adding lemon, apple cider, etc. I did this with hibiscus tea, which is a natural pH indicator, like litmus paper. The tea is bright red at acid pH and tastes quite sour. As you add L-arginine powder, the color of the tea starts to turn purple (pH neutral; gets blue towards alkaline pH). It won't taste as sour (and no fishy arginine taste--unless you add a lot of arginine and pass the pH ~7). I do hope that the arginine powder taken this way still has its efficacy. I am taking it to both help lower blood pressure (vasodilation) and to help with brain (recent study showing L-arginine reduces amyloid aggregates and improves cognition in mice). I have already seen some decrease in BP, but it could be the hibiscus tea. Hibiscus tea has numerous health benefits, but I don't want to erode my teeth enamel, or neutralize the pH with baking soda, which will add sodium and increase BP. Aiya.

  30 minute boner

  In 30 minutes you'll get an erection. It's a great sign to let you know when it's kicking in. Doesn't taste the best but that's because it's a fairly large dose compared to others. I've noticed a considerable difference in performance when working out. I'm lifting heavier and everyone notices the pump it gives definitely something you want to take before the gym. I've been taking it for a month now and I couldn't be happier with the results. Well done Nutricost I love the Isolate protein, creatine and lions mane options you guys are my favorite brand during my transformative adventure quality products, diverse options at great prices.

  This is solid craftsmanship, neutral tasting L-Arginine at a solid amount

  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.

  Disgusting taste fixed

  Does what it's supposed to but the taste is absolutely disgusting but if you add 1/4 teaspoon / one gram of citric acid the disgusting taste goes away.
