Creatine is one of the most researched sports supplements — effective and safe when used correctly — but a few common mistakes can blunt its benefits or cause avoidable side effects.

Why creatine works 

Creatine is a naturally occurring compound that helps regenerate adenosine triphosphate (ATP), the immediate energy source used during short, high-intensity efforts such as sprints and weight lifts. Supplementing with creatine monohydrate raises muscle creatine stores, improving strength, power, and recovery when combined with resistance training. 

Common mistakes people make

  1. Skipping daily consistency: Creatine works by saturating muscle stores — missing days or taking it only on workout days delays results. Daily dosing (even on rest days) is key. 
  2. Overdoing the loading phase: A common loading protocol (20 g/day for 5–7 days) speeds saturation but can cause stomach upset for some. A simpler alternative is 3–5 g/day from day 1 — slower, but effective and gentler on the gut. 
  3. Worrying about kidney harm without cause: In healthy adults, long-term studies show no evidence that recommended creatine doses harm kidney function; however, anyone with preexisting kidney disease should consult a physician first. 
  4. Poor product choice: Low-quality blends, proprietary mixes, or untested brands can include unnecessary fillers. Choose creatine monohydrate from a reputable maker with third-party testing. 

Timing, pairing, and dose — practical, evidence-based advice

  • Dose: 3 g/day is a practical, evidence-based maintenance target; 3–5 g/day is common. The UK nutrition authority has also recognised 3 g/day as a suitable intake for adults. 
  • Timing: Recent reviews find timing (before vs. after a workout) is not critical — what matters more is regular daily intake. If you prefer timing, taking creatine shortly before or after exercise (or with a meal) is reasonable; pairing with carbs/protein may slightly improve uptake. 
  • Hydration & GI care: Stay well hydrated and split doses if high single doses cause gastrointestinal discomfort. If you experience persistent stomach upset, lower the daily dose and avoid taking it on an empty stomach. 

Who should be cautious

Pregnant or breastfeeding people, those with known kidney disease, or individuals on medications that affect renal function should consult their doctor before starting creatine. For most healthy adults, evidence supports safety at recommended doses. 

Some helpful tips from the best doctor dietician in Dwarka, Dr. Pankaj Kumar

  • Take creatine daily (3–5 g) for reliable results — consistency beats perfect timing.
  • Loading helps speed results, but is optional; lower steady doses are effective and gentler.
  • Choose creatine monohydrate from third-party tested brands and stay hydrated.
  • People with kidney disease, pregnancy, or certain medical conditions must consult a clinician.
