Healthy Origins - L-瓜氨酸 10.6 盎司（300 克）

Many other companies source from overseas (China) but they do not. I contacted the company to verify where the raw product is sourced from. They said "L-Arginine and L-Citrulline raw material is processed in the United States. The starting raw material for L-Citrulline and L-Arginine fermentation is glucose from corn syrup. The corn is harvested in the U.S.A." Really appreciate their transparency and I think they have a more trustworthy and better value product.

Takes a little while to dissolve in water but virtually no taste and good quality.

Scoop may be at the bottom of the container, so you may need a long handled fork or such to find it. The product did not have much of a taste initially, but does have a somewhat unpleasant after taste though not enough to discourage it's use if I find it beneficial. Today is the first day I've used it; if I remember I'll update this review with more information later.

The powder on the left is Healthy Origins and the right is another brand. I keep coming back to Healthy Origins citrulline powder because it has absolutely no flavor. There is no weird aftertaste compared to other brands I have experimented with.

When this powder is mixed with water it is completely colorless and tasteless. The powder mostly dissolved but there was a little residue left over (see photo). The fact that it is colorless and tasteless means it can be combined into any drink. To test the effects on Nitric Oxide production I used NO indicator strips to test before and a couple of hours after drinking it. The indicator strips originally indicated "Low" and were in the "Optimal" range after using this mix. I sometimes find with a NO supplement it may take a couple of days to notice a difference. If you decide to try it, give it 2-3 days to try it out.
