October 30, 2009 Reviewer: Phillip in California I have been using the bulk L-arginine powder for several years. If you mix it with an equal amount of milk and French Vanilla creamer, it doesn't taste too bad! Couple of oz of each works for me. Experiment a little. Was this review helpful to you?

L-Arginine tastes bad, but the caps only have about 500mg. 1998 Nobel winners for medicine say that 4000mg or more are needed for best effect. That's a lot of caps. I'll find a way to take the powder. This is the best price for pure product that I have found. Was this review helpful to you?

But it works...I guess I'll find alternative ways to take it to not make it taste so bad. I gave this product a 3 rating because of the taste; but as far as the supplement goes - thumbs up!

You better try some capsules or another form of arginine. Was this review helpful to you? Yes  No See more reviews
