Evidence-based nutrition
We read the studies. You get the answers.
The research depth of PubMed. The reading experience of a magazine. The simplicity of pressing play.
Cold water sits in your stomach longer than warm water. The physiology is measured and direct: cold temperature suppresses gastric contractions, the rhythmic churning that pushes fluid toward your small intestine where absorption happens. At 2°C, those contractions slow and stay suppressed for over an hour. Warmer water moves through. Ice-cold water sits.
Sodium before exercise genuinely improves performance. Not in the theoretical, it-should-work-on-paper sense. In the measured, replicated, 14 to 26 percent longer before exhaustion sense. The numbers behind the pre-workout salt trend are real, and they're larger than most supplement ingredients can claim.
Carbonated water makes carbonic acid in your stomach, and acid near bones sounds like trouble. The proof seems obvious — cola drinkers show measurably lower bone density, and cola fizzes the same way your sparkling water does. Whether carbonated water reduces mineral absorption feels settled before you've looked at a single number.
