How we calculate this

Baseline

  • 35ml of water per kilogram of bodyweight (daily baseline).
  • Add 250ml if moderately active, or 500ml if very active.

Climate adjustment

  • Moderate climate: baseline ×1.10.
  • Hot climate: baseline ×1.20.

Caffeine and alcohol offset

  • +150ml for every coffee or caffeinated drink.
  • +150ml for every alcoholic drink.

Sachet guidance

  • Moderate to very active, or 2+ caffeine servings: we suggest 2 sachets.
  • Hot climate: we suggest at least 1 sachet in your day.
  • Otherwise 1 sachet covers most people.
