Sodium band is the most important variable to match to your use case. Low-Mid (under 300 mg/serve) suits daily desk hydration. Mid (300-700 mg) covers most general sports drinks. High (700+ mg) suits heavy-sweat training, hot conditions, fasted training, or salty sweaters. Tiered means the brand lets you pick the sodium level (Precision Fuel & Hydration's approach).
Sugar-free posture - 'Yes' means the brand's lineup is consistently sugar-free; 'Mostly' means a sugar-free option exists alongside sugar-containing SKUs; 'Mixed' means the standard products contain sugar with sugar-free Zero variants alongside; 'No' means the brand's formulation deliberately uses sugar (cane sugar, glucose-fructose blends) as part of its design.
