Creatine Loading Phase Calculator

Creatine loading is a supplementation strategy designed to rapidly saturate your muscles with creatine, a naturally occurring compound that helps produce energy during high-intensity exercise.

Loading Phase Formula: Daily dose = Body weight (kg) × 0.3 g/kg

This is typically split into 4 equal doses throughout the day for 5–7 days.

Maintenance Phase Formula: Daily dose = Body weight (kg) × 0.03 g/kg

After the loading phase, a smaller daily dose maintains elevated creatine stores.

What each variable means:

• Body weight — your current weight in kilograms or pounds
• 0.3 g/kg — the standard loading dose coefficient (approximately 20 g/day for a 70 kg person)
• 0.03 g/kg — the maintenance dose coefficient (approximately 3–5 g/day)

When to use this calculator:

• Starting a creatine supplementation program
• Adjusting doses after a significant weight change
• Deciding between loading and no-loading approaches

Practical example: A 180 lb (82 kg) person would take about 24.5 g/day during loading (split into 4 doses of ~6 g each) for 5–7 days, then switch to ~4 g/day for maintenance.

Tips:

• Take creatine with a meal or carbohydrate-rich drink for better absorption.
• Drink plenty of water — at least 8–10 glasses per day during supplementation.
• Creatine monohydrate is the most researched and cost-effective form.
• You can skip loading and just take the maintenance dose; it takes about 3–4 weeks to fully saturate muscles this way.
• Consult a healthcare professional before starting any supplement regimen.
