AMINO ALL STAR – L-Arginine does so much for your body—benefitting everything from your heart to your immune health. But while your body produces this semi-essential amino acid naturally, and you can get it from certain foods, it can be hard to make enough. That’s why a high-quality supplement is so important.

SUPPORT ALREADY-HEALTHY BLOOD PRESSURE & MORE – Your body uses L-Arginine for many different purposes—including maintaining already-healthy blood pressure. Another key use is tocreate nitric oxide, a chemical that helps expand your blood vessels. Arginine also supports healthy arterial elasticity.

IMMUNE HEALTH & BIOMARKERS – L-Arginine can help maintain a healthy immune response. It’s also been associated with already-healthy levels of C reactive protein, a biomarker that is used to measure cardiovascular health, especially as you age.
