Here is something very interesting. A quality amino acid manufacturer Kyowa Hakko came out with a combo of L-arginine and L-citrulline and showed that it increased nitric oxide bio availability in the body. See study here. But on the website they do not give you supplement companies whom you can buy this from. Thus I did the grunt work for you . Here is the brand you must buy in order to get the Kyowa Hakko L-citrulline and Ajinomoto L-Arginine and not some cheap chinese amino acids.
Here is the brand of l-arginine and l-citrulline that I recommend.
TAKING IT A STEP FURTHER WITH MY REVIEWS BY RECOMMENDING A BRAND!
Remember I’m a supplement expert with over 15 years experience in buying and manufacturing supplements. Anyone can recommend a supplement but isnt the next question always, “What BRAND is the best?”. Well that is the problem. You have sites like examine.com that tell you about the ingredients but stop there. That is pretty much worthless because you have no clue what to BRAND to BUY after that. So you’re left with searching forums and asking self-proclaimed experts or looking at reviews that most of the time are biased. The real answer is to ask an expert like myself. Asking questions on a forums only gets you amateur consumer responses which is quite frankly a ridiculous way to take a recommendation with something you’re putting into your body. But you’re in luck because I am a REAL supplement expert. I have over 10 years dealing with FDA lawyers, manufacturing consultants, employing dietary supplement experts, knowledge of the Code of Federal Regulations 111’s for dietary supplements, and much more! I am a qualified supplement expert manufacturer, not just a science guy. I am the real deal when it comes to recommending quality supplements because I take it a step further and recommend a brand and give you the reason(s) why!
