My husband takes 2 caps daily to help lower his blood pressure. It was running a little high and his doctor was starting to be concerned now after 3 months continued use it is normal again.

Thanks for your feedback!

Fantastic combo!

Ornithine is a precursor to Cituline which has been proven to assist with the uptake of Arginine. The two work synergistically together!

Thanks for your feedback!

Works so well for stomach aches due to proteins - take about 4 caps at a time (2-3 times a day) until your stomach ache is gone. This has been a lifesaver for me!
