Arginine-Citrulline Sustain, 120 Tablets

The quality of this Arginine-Citrulline Sustain Supplement is exceptional. The formula combines L-arginine and L-citrulline, both of which are well-known for their ability to boost nitric oxide levels in the body. Nitric oxide plays a crucial role in improving circulation and blood flow, which translates into better performance, faster recovery, and increased energy during physical activity.

Been using this Arginine-Citrulline combo for about 4 weeks and loving the sustained release formula. Take 2 tablets before my morning workout and another 2 before evening training. The 120-tablet bottle lasts a month at this dosage, which is pretty reasonable. The sustained release really makes a difference - you can feel the effects lasting longer compared to regular arginine supplements. Love that it's vegan and uses clean ingredients. The 500mg/500mg ratio of arginine to citrulline seems perfect, and the added vitamin C is a smart touch for absorption. No stomach issues either, which can happen with other NO boosters. Definitely notice better pumps and endurance during workouts. Feel like I've found my go-to NO support supplement. Others in my gym have noticed my improved workout performance - that's when you know it's working!

Good package and dose. Ingredients are really good and quality is even better!

Hello, I am very satisfied with the product and will purchase it again when I run out. Thank you.

I brought this package for the benefit of adding blood flow to my body. I suffer from CCCA which is a type of Alopecia that causes burning in the scalp resulting in hair loss. It works. The benefit is amazing. I believe my follicles are receiving blood flow as my hair is coming in. What a surprise.

I’ve been taking Jarrow Formulas Arginine-Citrulline Sustain (2 tablets daily, 500 mg arginine + 500 mg citrulline + 10 mg vitamin C) for four weeks and noticed improved blood flow, firmer muscle pumps during workouts, and faster recovery afterward. The sustained-release tablets dissolve smoothly with water and deliver a steady nitric oxide boost without the crash of high-dose arginine alone. With 60 servings per bottle, it lasts two months at one serving per day—excellent value at about $0.40 per dose. Non-GMO, vegan, gluten-free, and made in a GMP-certified facility with third-party testing, I trust its purity. Minor note: the tablets are on the larger side, so I recommend plenty of water when swallowing. If you found this helpful, please click “Yes”!

I love that this supplement provides a steady release of nitric oxide support, helping with circulation and overall cardiovascular health.

It's easily one of the top 3 supplements that help with my ME/CFS symptoms, especially when taken before sleep, to reduce the exhaustion that my immune system causes during sleep. Jarrow offer a sustained release variant of these NOS precursors combined, which helps even more to improve availability longer during the night.

Thank you for providing such outstanding supplements! The quality is exceptional, with thoughtfully selected ingredients that offer remarkable health benefits. Your products have made a significant positive impact on my overall well-being. I also appreciate the secure and reliable packaging. Thanks again, iHerb!

Arginine and citrulline are amino acids often used for their potential benefits in promoting nitric oxide production, which can improve circulation and endurance. The main ingredients, L-Arginine and L-Citrulline, work synergistically to support nitric oxide production in the body. Since this is in capsule form, there is no taste, which is ideal.
