## Description

Now L-Arginine comes in extra strength 1,000 mg tablets and is non-GMO. Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion, as well as in DNA synthesis and protein production. It is an important precursor of nitric oxide (NO) and thus plays a role in the dilation of blood vessels. The L-Arginine used in this product is pharmaceutical grade. Natural color variation may occur in this product.

## Questions & Answers

**Q: is this tested ??**
A: Yes from what a health magazine that my wife got states that it has been tested.She has been taking it for over 2 weeks now and she has lost weight from taking it.

**Q: Is this a sustained release version of L-Arginine?**
A: This is not a 'capsule' with tiny pellets inside, but rather a tablet.  It's large so I put it into a couple tablespoons of water overnight and just gulp it down followed by water.

**Q: is there an improvement in urination control at night with only 1 capsule they recommend?**
A: My husband and I started taking Solaray Olive Leaf Extract to help keep from getting the flu and within a week we both noticed we weren’t waking up in the middle the night. An unexpected positive side affect. 250mg 17% 120caps costs between $24 - 28 here’s the link and worth a try. Hope it helps...

### ⭐⭐⭐⭐ Good product but...
*by N***R on December 13, 2025*

Overall solid product as you are using one pill instead of the usual 2-3 pills. The drawback? The pills are pretty big, and I feel like I am playing Russian roulette and chancing a choking accident. They aren't capsules either, just dense pills so good luck getting it stuck in your throat. For this reason, I'm going to switch to powder instead.
