L-arginine Plus® is based on a Nobel Prize winning medical breakthrough and the discovery of nitric oxide, which some consider the most important advancement in the fight to maintain healthy blood pressure and a healthy cardiovascular system!

Studies indicate people with high blood pressure or high cholesterol may be deficient in the life-saving molecule Nitric Oxide.  Adding enough L-arginine and L-citrulline to your daily cardio regimen, helps provide more support for your heart health. Until recently the cost of supplementing your diet with these amino acids could exceed $100 per month.

But now, there's L-arginine Plus® Cardio Health Formula, an affordable alternative to the expensive products first introduced by network marketing companies.

Theresa KrenzExtremely excellent product, I love it! I feel an overall increase of energy and stamina to do tai chi and Qigong, which is low impact..does take much focus and mental coordination. I thank you for putting together the right amount of ingredients so I don't feel that over wired feeling after taking this wonderful healthy drink.

Keran Humble I bought this for my husband and he loves the way it makes him feel. He simply will not go a day without it.

Lisa Johnson Matlaf I bought this with the intentions of getting more lean. Not only has this satisfied that need, but I've been feeling more alive in general and my energy level is higher throughout the day.

Elizabeth on AmazonThis is the only L-argenine that my body absorbs. High quality and you can actually feel the difference between this brand and the other cheap ones out there. You want quality when it comes to supplements.

Golden State legend Rick Barry is one of the NBA's Top 50 players and the only player to ever lead the NCAA, ABA, and NBA in scoring.

He continues to compete and won the RE/MAX World Long Driver Championship five times, twice as grand champion.

Rick turns 72 this coming year and loves the suppoprt and energy he gets from taking L-arginine Plus®

"I won't go a day without this awesome product. Felt so good on day 1 of taking it that I haven't missed a day in over 6 months... I breath better, wake up much more alert even if I get very little sleep, and I just have an overall feeling of wellness. I buddy up and split a 6 pack with free shipping which makes the great price even better. If you aren't taking L-arginine Plus®... do yourself a favor and give it a go... peace!"
