Summary of supporting evidence

In some instances, phosphate has been shown to enhance VO2max ^{2, 3}, anaerobic threshold³, and cycling TT performance.⁴ However, in the case of repeated sprints, the magnitude of benefit has been shown to be varied and unclear.⁵ Finally, there is also a large amount of contrary evidence from the same physiological and performance measures that suggests phosphate supplementation (in isolation, or in combination with other buffer agents) has no impact on exercise capacity or performance outcomes.^{6, 7, 8, 9}
