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.

Lowers your Blood pressure.
Great product to lower your blood pressure without the use of prescription medication. I've been on prescription meds, Lisinopril for hypertension and controlled for awhile at 5mg but I recently changed to Losartan due to the cough getting worse from side effects of lisinopril. But losartan isn't as effective and my BP was not controlled and I refuse notice to continue with higher dosage or add another pill for BP. I found L-Arginine which was recommended by one of the associates at Warwick Store (Norm). I've been recommending not to others.

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.
