Life Extension L-Arginine Caps, 700 mg - Promotes Arterial Health - Gluten-Free, Non-GMO - 200 Capsules
Key item features
- 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 to create 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.
- Ingredients matter – We use only pure, high-quality ingredients. The majority of our products are non-GMO and gluten-free—and a Certificate of Analysis is available for every one.
- Live your healthiest life - For over 40 years, we’ve been developing advanced, effective formulas made with the highest standards and based on the latest scientific findings. We believe the answers to a healthier, richer life are within reach, and that rigorous scientific research is the path to get us there. That’s why so many of our nutritional formulas are designed using specific ingredients and amounts based on scientific studies.

Superb Skin Supplement
I'm am more than thrilled with the results of all my supplements that I've chosen to purchase from Life Extension. I have girls more than half my age now asking me to email them my list of Life Extension products so they can age like me. SO happy with the results that adding L-Arginine have produced. When I combined it with Lysine and Proline, my skin looked years younger.

Helps with blood flow.
I work out regularly. I use L-Arginine to help with my blood flow. It helps to keep my capillaries open so I can work out harder without having adverse effects on my blood flow. [This review was collected as part of a promotion.]
