Creatine Water Intake Calculator

Creatine pulls water into your muscles. Use your body weight, dose, and training load to get a daily hydration target you'll actually hit.

Most people take 3–5 g/day. Loading phase is ~20 g.

How much water should you really drink on creatine?

Creatine works by drawing water into your muscle cells, which is part of why it improves strength and recovery. The flip side: your overall fluid needs go up. If you don't replace what's pulled into your muscles, you're more likely to feel cramps, bloating, headaches, or sluggish workouts.

The simple formula

A practical baseline is 0.5–1 oz of water per pound of body weight (roughly 30–60 ml/kg). On creatine, add about 16–32 oz (500–1000 ml) on top to cover the extra water held in your muscles. Then add another 16–24 oz per hour of training to replace what you sweat out.

When does it matter most?

During a creatine loading phase (around 20 g/day for 5–7 days) your body is rapidly saturating its stores, so the hydration bump matters more. On a steady-state 3–5 g/day dose, you mainly need to keep hydration consistent.

Signs you're under-hydrated on creatine

  • Dark yellow urine throughout the day
  • Muscle cramps during or after training
  • Headaches, especially mid-afternoon
  • Bloating without changes in diet
  • Workouts feel harder than they should

A note for women in perimenopause

Hormonal shifts in perimenopause can already affect fluid balance, energy, and muscle recovery. Creatine is one of the most studied supplements for women over 40, but pairing it with steady hydration is what makes it actually work. Lila is built around this kind of body-aware guidance.

Hydration is one habit. Lila handles the rest.
