I use NOW brand L-arginine powder. It comes in a large container and is fairly inexpensive. The powder has an unpleasant bitter taste. I buy empty gelatin capsules (also NOW brand, in the triple zero size, which holds about 1500mg). So when I take the L-arginine, I put the powder in an empty capsule first.
It's quite a bit cheaper to do it that way, as opposed to buying it already in the capsules. |
