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.
