Very satisfied with the quality-price ratio!

I chose the Vitacost version because 300 tablets at the 1,000 mg concentration are enough for a long time. I take them before training and feel a much better pump and increased resistance to effort. The pills are quite large, but with enough water they are swallowed without problems. I highly recommend!

I bought this arginine supplement for my husband, on the advice of a doctor, for additional support of blood circulation and overall tone. I decided to try it. It has a high dosage of 1000 mg per tablet; they're large but easy to swallow. My husband says he feels good when he takes it, especially the feeling of energy and overall tone, and he's able to better handle workouts (and he's 65+). There are plenty of tablets in the package, so they'll last a long time.

1000 mg of L-arginine in a convenient daily dosage of one tablet. Vitacost offers a 300-day supply in one bottle. This means almost 10 months of circulatory support.

I bought this because it contains ingredients necessary for children's growth. It doesn't have a particular size, taste, or scent, but it is fine to eat without any aversion.

I take L-arginine, one tablet daily, for three months, for my cardiovascular system. I'm happy with the quality. After a month of taking it, my heart pain subsided and my blood pressure stabilized. The tablets are large and don't have much of a smell. I recommend them.

Not satisfied

It smells like alcohol, which is unacceptable and ruins the taste. My son refused to use it.
