According to scientists, citrulline may contribute to increasing training efficiency, increasing the concentration of nitric oxide in the blood and intensifying the effect of so called muscle pump. 

Citrulline malate has strong hygroscopic properties (it clumps), this is a natural feature. 

There is no added artificial anti-caking agents or substances that block this process. Caking doe not affect this product in any way, no chemical reactions occur and citrulline malate is still the same. The raw material is already quiet clumpy, during production special grinders are used to bring it to loose form so the packaging process can take place, this starts to clump again few hours after this point.
