This worksheet calculates label amounts; it does not prescribe an intake.

COPY THE EXACT LABEL
Product / version / flavor / label date:
Tablet count per labeled serving:
Water volume per labeled serving (mL):
Sodium per labeled serving (mg):
Carbohydrate per labeled serving (g):
Caffeine per labeled serving (mg), or record unknown:
Preparation, closure and storage directions:

CALCULATE THE PREPARED DRINK
Follow the product's mixing directions.
Bottle water volume (L) = volume in mL / 1000.
Number of labeled servings prepared:
Full-bottle sodium (mg) = labeled sodium x servings prepared.
Full-bottle carbohydrate (g) = labeled carbohydrate x servings prepared.
Full-bottle caffeine (mg) = labeled caffeine x servings prepared.
Sodium concentration (mg/L) = bottle sodium / bottle volume in liters.
Fraction consumed = amount consumed / full prepared volume.
Consumed nutrient amount = full-bottle amount x fraction consumed.
For multiple bottles, add the amounts actually consumed.

FICTIONAL EXAMPLES (not product recommendations)
A: 1 tablet in 500 mL; 500 mg sodium, 2 g carbohydrate, 0 mg caffeine.
Sodium concentration = 500 / 0.5 = 1000 mg/L.
B: 1 tablet in 750 mL; 250 mg sodium, 4 g carbohydrate, 50 mg caffeine.
Sodium concentration = 250 / 0.75 = about 333 mg/L.
Two complete bottles of B: 1.5 L, 500 mg sodium, 8 g carbohydrate,
100 mg caffeine. Half one bottle: 375 mL and 125 mg sodium.

INTERPRET
Which composition serves the activity and existing food/drink plan?
What caffeine or carbohydrate comes from other sources?
What product claim needs human evidence beyond the composition label?
Avoid forcing fluid or improvising concentrated mixtures.
For a demanding-event plan, consult an athletic trainer/sports dietitian.
