Parents are happy
I bought L-arginine for my parents who are over 70 years old. They are very happy with it and want to continue to take it.

Surprisingly effective
Works surprisingly well for it's intended purpose. I have not had the problem with crumbling in pill-minders that other users have noted (humidity? lack of humidity?). These are very large caplets. While I normally have no problems with supplements or medicines, this one can be a challenge.

Turns to dust
Don't take it out of the bottle. Turns to dust within a few hours when storing in pill-minder.

Hello, does it make a difference to take 1 tablet three times a day versus taking three tablets all at once? Could I take one in the morning and two in the evening? Thanks!

BEST ANSWER: They should be taken as three divided doses, so they should be taken three separate times daily.
