How much does creatine monohydrate cost?

Creatine monohydrate costs 0.05 to 0.30 dollars per serving in 2026. A 300-gram tub of Optimum Nutrition Micronized costs 24 dollars and lasts 60 servings at 5 grams each, which is 0.40 dollars per serving.

Is creatine monohydrate safe?

Yes, creatine monohydrate is safe for healthy adults at the recommended dose of 3 to 5 grams per day. The International Society of Sports Nutrition reviewed the research in 2025 and found no adverse effects in healthy adults taking the recommended dose for up to 5 years. The most common side effects are mild stomach upset and water retention, which usually go away after a week. People with kidney disease should consult a doctor before taking creatine. The FDA does not regulate supplements, so look for a third-party tested product like Thorne NSF Certified for Sport or Optimum Nutrition, which is Informed Choice certified.

Do I need to load creatine?

No, you do not need to load creatine. A loading phase of 20 grams per day for 5 to 7 days saturates the muscle creatine stores faster, but it also increases the risk of stomach upset. A maintenance dose of 3 to 5 grams per day reaches the same muscle saturation in about 3 to 4 weeks. The right move for most people is to skip the loading phase and start with a maintenance dose. Pair the dose with a meal that includes carbohydrates, which improves absorption. Take the dose at the same time every day to build the habit.

When should I take creatine?

Take creatine at any time of day that you can stick to. The original research suggested a post-workout window, but more recent research shows that timing does not matter as long as the daily dose is consistent. The most common time is right after a workout, paired with a protein shake. The second most common time is in the morning with breakfast. The least effective time is before bed, because the muscle protein synthesis drops during sleep. The right time is the time you will stick to every day. Most people find morning or post-workout easiest.

How long does it take for creatine to work?

Creatine takes 2 to 4 weeks to fully saturate the muscle creatine stores at a maintenance dose of 3 to 5 grams per day. With a loading phase of 20 grams per day for 5 to 7 days, the saturation happens in 5 to 7 days. Most people notice a 1 to 3 pound weight gain in the first 2 weeks from water retention in the muscle, which is normal and expected. The performance gains, like one extra rep at the gym or 5% more power on a sprint, show up in 2 to 4 weeks. The right move is to take creatine every day for 4 weeks, then judge the results.
