Our lack of an acute alkalotic shift in acid-base balance contrasts with other recently published work by König and colleagues [3]. These researchers presented significant increases in both blood and

urine pH following acute multi-mineral supplementation in both males and females. The discrepancy between studies may illustrate the large variation between manufacturer recommendations on dosage administration levels and supplement contents (Table 1), as selleck inhibitor high concentrations of potassium contained within such supplements has shown to effect acid-base regulation to varying degrees [4]. Despite the high concentrations of metabolizing anions in fruits and vegetables in general and their purported role in absorption of H+ [3], EG may not contain sufficient levels of pro-alkalizing nutrients to enhance blood-buffering capacity after a single ingestion [3, 6]. As previously addressed, inducing acute increases in blood buffering capacity for performance enhancement via exogenous buffer ingestion often results in increased gastrointestinal (GI) distress [2, 7]. An

underlying aim of the current report was to not only use the NaHCO3 condition to compare acute blood buffering changes, but also to address the potential side-effect LY2606368 issue. Although our standard dose was on the low end of NaHCO3 doses [1, 7], we felt that for a preliminary study this would be sufficient for comparison with the EG condition. Similar to other reports [2, 8], we observed a large degree of variability between Protirelin individuals for incidence and severity of symptoms between conditions (Figure 2). We acknowledge that this observation is based on a 0.1 g·kg-1 and not a 0.3 g·kg-1 NaHCO3 load, and that the GI distress reported in other studies in all likelihood resulted from the higher overall load of NaHCO3. However,

we believe that future studies observing the chronic ingestion of EG do not need to consider GI distress in their methodologies. In conclusion, acute ingestion of Energised Greens™ has only minor affects on blood acid-base regulation at rest and at 9 g would not induce sufficient changes in blood buffering capacity. Further research is warranted to investigate the potential chronic or dosage related loading effects of this product and other fruit and vegetable extracts upon blood acid-base regulation.
