## Description

Product Description Protein Metabolism* Muscle Maintenance* Arginine and citrulline are two amino acids that are integral to protein metabolism and utilization, as well as to the maintenance of muscle tissue.* Both are key intermediates in the urea cycle, where they participate in the detoxification of ammonia via the production of urea.* In addition, any arginine not converted to urea enters general circulation where it is distributed to various tissues and metabolized for other uses such as protein synthesis.* Natural color variation may occur in this product. Brand Story By NOW Foods

Review: NOW Sports Nutrition Arginine & Citrulline – Solid Amino Acid Support - I’ve been using the NOW Sports Nutrition Arginine & Citrulline capsules (500 mg / 250 mg) regularly, and they provide good support for my workouts and recovery. The combination of these amino acids seems to help with blood flow and muscle endurance. The capsules are easy to swallow and vegan-friendly, which I appreciate. The 120 count gives good value and lasts a while. If you want a reliable arginine and citrulline supplement to boost performance and recovery, this is a solid option.
Review: Relief from Migraines - I've suffered from migraines all of my adult life. A few years ago my doctor, although my blood pressure was on the low side of normal, put me on a blood pressure medication that gave me some relief. But I still got 2 to three migraines a month and the medication made me less tolerant to exercise. I gained almost 50lbs. My son, who is a body builder, told me about arginine and citrulline as something that would help me with my exercise tolerance. I tried it just before doing some long walks and I can't say I saw a difference so it just sat on my shelf. Then one day I saw it on the shelf and decided to look at it a bit closer. That's when I discovered that it could help with migraines. So I began taking a gram in the morning and another at night. No more migraines. None. I took myself off of the blood pressure meds and my blood pressure is still on the low side of normal. The best part is I have more energy and I've lost 10 pounds in the first month on it. I can't say enough good things about this product. It works much better than I could have hoped.

## Questions & Answers

**Q: Is it vegan?**
A: I just spoke with their nutrition department at the manufacturing plant in Bloomingdale, IL, and the arginine is derived from feathers and is thus NOT vegan.  I am bummed as I had been using this product for some time now.  Ajimoto/Ajipure pharmaceutical-grade amino acids are however vegan.  Hope this helps someone.

**Q: Does this product conflict with Lisinopril?**
A: Not sure but I did read  something. I think it was on webmd.

**Q: What does free form L Arginine and L citrulline mean?**
A: Free-form amino acids refer to single amino acids that are already in a pre-digested form and ready to be used by your body. Some nutritional products, especially amino acid blends, contain whole proteins and large peptides (chains of amino acids), which the body must first break down into smaller peptides and individual amino acids before use. For faster utilization and better bioavailability, look for free-form amino acids.

**Q: What is the prop 65 warning about ?**
A: The California Prop 65 warning may inadvertently appear on the product page. This warning does not apply to this product and can be ignored, it is no longer live on this product page upon checking.
