What is Stearoyl Vanillylamide ?

Stearoyl Vanillylamide is an analog of Capsaicin, a compound found in various species of Hot Pepper which is primarily responsible for the spiciness. Unlike Capsaicin, however, Stearoyl Vanillylamide is non-pungent, which actually makes it easier to use in powder-form supplements.

How Stearoyl Vanillylamide works

Stearoyl Vanillylamide has been shown to increase swimming capacity in mice, compared to mice given a placebo.

According studies: Intravenous injection of stearoyl vanillylamide (C18-VA), a nonpungent capsaicin (CAP) analog,enhances adrenaline secretion significantly and as effectively as CAP in rats. Because swimming capacity was enhanced by CAP in mice due to CAP-induced adrenal catecholamine secretion, we investigated the effects of oral administration of C18-VA on swimming capacity using an adjustable-current water pool. Male Std ddY 6-wk-old mice were fed a commercial diet for this study and one group was orally administered C18-VA via a stomach tube. 

Treated mice were able to swim longer before exhaustion than the control mice (62.9 6 5.6 vs. 49.6 6 7.0 min, P , 0.05). The swimming capacity of two groups administered C18-VA (0.02 and 0.033 mmol/kg) was significantly greater than that of those administered vehicle alone, (P , 0.05). Substance P concentration in cerebrospinal fluid, which is involved in pain transmission and is the first direct measure of pungency, was not affected by C18-VA administration. In an experiment examining the effects of C18-VA on serum adrenaline concentration, adrenaline was significantly greater in C18-VA treated mice than in controls at 2-h post-dose (C18-VA group, 26.09 6 2.82; control group 13.29 6 0.96 mg/L, P , 0.01). In a separate study free fatty acids in serum were elevated in treated mice at 2-h post-dose (P , 0.01). While serum glucose concentration was not affected. These results suggest that C18-VA increased swimming capacity of mice via adrenaline release, independent of pungency.
