In the world of nutritional supplements, knowledge is king. It’s easy for a product to make outrageous claims but it always comes down to one question, does it work? To answer this question you can take two approaches, you can try it for yourself, or you can research. The preference I use is research. It takes time but may save money. I take a two tiered approach to researching supplements. I first look at product reviews, some are more helpful than others as you’ll find, but can be a good way to gauge overall effectiveness, and who is it helping. You can look at it from an age, health, gender, medical history, and general situation of the person writing the review. Ask yourself, was any particular group helped by the supplement? Do I fit in this group? Secondly and most importantly look at medical publications.

Many schools of medicine across the county conduct tests on the effectiveness of supplements and report the findings through medical journals. Doctors review and use these journals and as a base within their own research, ideas and treatment. Medical journals along with any government run websites are a great tool in trying to determine if a supplement is worth your time. When it comes to the case of L-arginine there has been extensive research on the topic. It’s easy to get lost on the internet when conducting research but please stay focused on medical journals and government run sites for information, as many companies that produce and sell L-Arginine products often make claims you could define as “over the top.” Below are some links to credible resources on the effects of Nitric Oxide (synthesized L-Arginine).
