Not in moderation.
If you’re enjoying a few cups of coffee or tea a day, then you can rest assured a moderate amount of caffeine doesn't cause you to lose more fluid than you ingest, says Lisa Renn, accredited practising dietitian and spokesperson for the Dietitians Association of Australia. "There is evidence that caffeine in higher amounts acts as a diuretic in some people, but moderate intake is actually not that significant," Renn says.
Conclusion: be sensible, moderate your caffeine intake and enjoy your mind and body boost. With TrueStart you can guarantee a caffeine boost whilst making sure you don’t overdose.
