Discovery studies have identified many metabolites contained in human sweat. However, quantitative analysis of the sweat metabolome content remains mostly unknown. Furthermore several attributes, including rate, have been defined to affect sweat metabolite content, while other effectors, like diet, remain unknown. This study works to quantitatively define the metabolite impact caused by nutritional supplementation. To better understand the effect diet plays, a LC-MS method was developed focusing on improving resolution and peak width. While the literature provided examples of how diet affected sweat metabolite concentrations, the long-term effects of diet have not been explored. The experiment described here attempts to fill that gap. Partial data separation was found among groups ingesting high and low nutritional supplementation. Several subjects given the high nutritional supplementation had decreased sweat metabolite concentrations after twelve weeks. These results suggest nutritional supplementation can impact the sweat metabolome, and diet should be considered in biomarker discovery experimentation.
