About this item
Product details
Doctor’s Best L-Arginine supplies an amino acid vital in the synthesis of nitric oxide, which is an essential compound that helps blood circulation. Arginine-derived nitric oxide benefits wound healing and overall circulation, and has been shown to help increase mental acuity, immune function, and memory.* Research suggests that L-Arginine supplementation helps increase muscle mass and may also positively be beneficial in improving endurance as it is a precursor to creatine, which helps supply energy to all cells of the body.* At Doctor’s Best, we lead with science. Our products are backed by research and crafted using pure ingredients carefully sourced from around the globe. Since 1990, we have dedicated ourselves to providing highly effective nutritional supplements that enable you to live a healthier lifestyle. We want nothing more than to see you and your family thrive!

Keeping It Real
Mixes well with smoothies, cereal, yogurt, and almost anything and leaving no aftertaste. I bought this several times before and will continue to.

Cost effective but hard on the taste buds!
This is definitely cheaper than tablets but the taste is very unique. I recommend you put some water in your mouth and then pour a scoop into your mouth and swallow. I do not recommend adding it to a shake or other drink since the taste is so strong.
