Salty.
I started adding this to my coffee and it is very salty. I checked the ingredients and nothing about salt, surprisingly. It makes coffee disappointing. I hesitated on giving it 3 stars thinking I may get use to it but I may have to return. Does arginine have a lot of salt normally? I had some from another brand and it isn't salty.

Grape Juice
I see people here don't like the taste. There are no good tasting L Arginine Powder. I mix my powder with diet welches grape juice and I can barely taste the l arginine. I tried to mix it with soda and other juice before and it didn't help. I tried grape juice and it worked for me. Hope this helps.

This is unflavored but it has a heavy sodium taste.
The label states no salt. But it has a heavy sodium taste going down and even after. I've tried mixing this with different carnation instant breakfast shake packets and still has a heavy sodium aftertaste. It's hard to choke down this product. The only reason I give it two stars is because It does work but if you don't have taste buds you should be fine.

    L-Glutamine is a flavorless, easy-mixing powder and an extremely versatile free form amino acid formula. It is the most abundant, naturally occurring amino acid in muscle tissue, but it can be depleted during prolonged training. Supplementing with L-Glutamine replenishes depleted stores, to help build new lean muscle and protect hard-earned gains by supporting protein synthesis. L-Glutamine also supports acid-base homeostasis. L-Glutamine supports post-workout muscle energy repletion, volumization, and repair. This "conditionally essential" amino acid functions as a critical factor in muscle form and function.† Supports Muscle Cell Volumization And Muscle Development Taking L-Glutamine supplements will help you improve exercise performance and gain muscles. The supplement also hydrates your body cells which are critical for repair and growth. Replenishes Depleted Glutamine Levels When one is stressed, ill, or injured, the L-Glutamine levels will go down, causing your body to look for the amino acid in your muscles to fill the gap. Glutamine supplements can support faster recovery for several ailments.
