This supplement has helped lower my BP, eased joint pain and negated some of the ongoing side effects from my prescription meds.

It's been over a decade since I accidentally stumbled across some studies that showed L-Arginine helped men perform better sexually due to the way it affects nitric oxide in the body (I worked in a medical department at the time, though I wasn't yet a registered nurse). I'm a Gen Xer, I guess (born 1967) and was always a tomboy, so I have a lot of male friends. I like to share knowledge, especially little known knowledge. So I told all of them, hey, guess what I read...?

Well, now it's apparently common knowledge, but it wasn't for each guy I told, when I told them! Privately they have all come and thanked me later and most have reported success. One was on SSRI antidepressants that totally killed his libido and his functioning. He started supplementing with L-Arginine and gushed to me like a year later that I saved his relationship with his girlfriend (now his wife). Another of my friends is a body builder and fitness model (wow, this makes me sound way cooler than I am -- weird) so he knew the benefits of supplementing but not about L-Arginine's other benefits. Yet another friend has told me (and so has my boyfriend, not that I wouldn't have noticed myself!) that the quantity and quality of his, uh, emissions is increased by L-Arginine supplementation.

I discovered, over time, that L-Arginine has a lot of other health benefits (due to the way it acts on nitric oxide in the body... go figure! jk!). It ALSO has the power to be female Viagra (but back then I really didn't have any problems in that department; my antidepressants were not SSRIs) so, ladies, help yourself.

We're all 10+ years older now and by all reports, L-Arginine seems to help a lot -- even me. I'm 45 now and have no evidence (yet) of menopause.

I've noticed a lot of fat burn when taking these. While I wouldn't say they are a "miracle" pill they help burn and synthesize protein. Work well with regular diet and exercise. Great for building muscle. Since starting them, I've cut 20lbs and gained a decent amount of muscle. Great supplement to help get into shape.
