About Joe Costello CNC

In order to help people reach their fitness goals, I have personally tested and reviewed hundreds of supplements to find the best of the best!

Hi, everyone! I’m Joe Costello

I’m not just a supplement analyst. I’m an extremely qualified one! I am a Certified Nutrition Coach (CNC) and actually received my certification directly from the National Academy of Sports Medicine. I am also a Nutrition & Wellness Consultant, certified by the American Fitness Professionals Association (AFPA). I specialize in sports nutrition and dietary supplement development, which is actually where my career started! My first job ever was literally in a supplement factory in Chicago called Nutrivo.

Through my 10 years of experience in the supplement industry, my training as a Nutrition Coach, my training as a Nutrition & Wellness Consultant, my experience in a high level football program, and my personal fitness journey, I have learned everything there is to know about supplements. But don’t take my word for it! The more you read on this site, the more you will realize exactly how well versed I am in nutrition and supplementation.

So, Who Am I?

I have worked in the sports nutrition industry for over 10 years. I started out as a laboratory assistant in a supplement manufacturing facility, where I would quite literally help formulate supplements from scratch. That experience is what makes me so good at evaluating Supplement Facts Panels, dosage sizes, ingredient efficacy, etc.

Ultimately, I believe my CNC certificate, NWC certificate, E-Books, fitness programs, and supplement manufacturing experience make me a highly credible and knowledgeable supplement analyst, which is why you can trust that my supplement reviews are accurate. After all, I am very literally a certified expert when it comes to supplements!

So, What Is The Purpose of This Site?

I have written over a hundred reviews on this site using the Supplement Facts Panel analysis formula I developed myself throughout my many years of developing and evaluating supplements. I also personally test many of the supplements I review and often factor my personal experience into my reviews. Prior to entering the nutrition industry, I was a football player (linebacker for those who are curious) and graduated from the University of Iowa. The reason I am bringing up my experience in a football program is because I learned a TON from my coaches about proper nutrition and supplementation. I wouldn’t be where I am today without them. That experience helped contribute to my vast amount of knowledge regarding which supplements are effective, and which ones are not.
