Optimum Nutrition Creatine can boost your workout results by up to 15%. Athletes and gym-goers have trusted this supplement for years. If you want to get stronger, more powerful, and build more muscle, knowing how to use this product correctly is important.
What Is Optimum Nutrition Creatine?
Optimum Nutrition Creatine is a high-quality supplement made by one of the most trusted brands in fitness. Their product is known for being pure and effective.
Creatine is a natural compound found in some foods and made by your body. It helps create energy during short, intense activities like lifting weights or sprinting. According to the Mayo Clinic, it’s one of the most researched supplements available.
| Form | Purity | Mixing | Serving | Size |
|---|---|---|---|---|
| Micronized powder | 99.9% pure | Mixes easily | 5g (1 teaspoon) | 600g (120 servings) |
The Micronized Creatine Powder is their main product. It dissolves better than regular creatine, making it easier to drink and for your body to use. For information on how supplements fit into a balanced diet, check out our article on 12 Best Mediterranean Diet Dinners.
How Optimum Nutrition Creatine Works
Creatine increases your body’s energy stores. It helps your muscles produce more ATP, which is the fuel your muscles use when working hard.
During intense exercise, your muscles quickly use up their energy. With more creatine, you can:
- Do more reps
- Lift heavier weights
- Recover faster between sets
- Keep your intensity up during workouts
Research from the International Society of Sports Nutrition confirms that creatine is one of the most effective supplements for improving exercise performance and building muscle. For natural ways to boost performance, also see our article on 15 High Protein Vegetarian Snacks That Boost Energy.
Benefits of Optimum Nutrition Creatine
Muscle Growth and Strength
Optimum Nutrition Creatine helps build muscle in two ways: it lets you train harder, and it pulls water into muscle cells, creating a better environment for growth.
Studies published in the Journal of the International Society of Sports Nutrition show that people taking creatine while weight training gain 2-4 more pounds of muscle than those not taking it.

Better Power Output
Athletes in power sports (sprinting, jumping, weightlifting) see great benefits from creatine. Research published in the Journal of Strength and Conditioning Research shows it can improve performance in these activities by 5-15%.
Faster Recovery
Creatine may help reduce muscle damage after hard workouts, helping you recover faster. This means you can train more often, leading to better results over time.
Brain Performance
New research from Frontiers in Psychology suggests creatine may also help brain performance, especially during stressful tasks or when you’re tired. While most people use it for physical benefits, this mental boost is an interesting extra advantage. For more on brain health, see our article 10 Science-Backed Ways to Boost Your Brain.
How to Use Optimum Nutrition Creatine for Best Results
How Much to Take
The most research-backed way to take creatine follows two phases:
Loading Phase (Optional):
- 20g daily (4 servings of 5g each) for 5-7 days
- Spread throughout the day
- Quickly fills your muscles with creatine
Maintenance Phase:
- 3-5g daily (1 serving)
- Can be taken any time
- Keeps creatine levels high
Many people skip the loading phase and just take 5g daily. This works too but takes longer (about 3-4 weeks) to reach full effect.
When to Take It
Research published in the Journal of the International Society of Sports Nutrition shows that taking creatine consistently matters more than when you take it. However, there are three common approaches:
- Before workout: Taking it 30 minutes before exercise may help during your workout.
- After workout: Some evidence suggests taking it after your workout might be slightly better due to increased blood flow to muscles.
- Same time daily: Taking it at the same time each day ensures your creatine levels stay consistently high.

What to Mix It With
Optimum Nutrition Creatine dissolves best in warm liquids but can be mixed with:
- Water (simplest)
- Juice (sugar may help absorption)
- Protein shakes (convenient if already using protein)
- Pre- or post-workout drinks
The micronized formula helps prevent the grittiness sometimes found with regular creatine.

Common Questions About Optimum Nutrition Creatine
Will it cause water retention or bloating?
Some users experience mild water retention during the first week, especially during a loading phase. This is normal and temporary. The extra water in muscles actually helps with strength gains. Most water weight is held inside muscle cells (making muscles look “fuller”) rather than under the skin (looking “bloated”).
Do I need to take breaks from using creatine?
Current research says taking breaks isn’t necessary. Studies following people using creatine for up to four years show no bad effects. Your body naturally makes and breaks down creatine, so supplementing appears safe for long-term use.
Can women take Optimum Nutrition Creatine?
Yes. Women benefit from creatine similar to men, getting increased strength and power. Despite some myths, creatine doesn’t make women look “bulky” because of their different hormones. Many female athletes use creatine to improve performance and recovery.
Will it affect my weight loss goals?
Creatine has no calories and won’t directly impact fat loss. However, the increased training intensity it enables can help burn more calories. The added lean muscle can also increase your metabolism, potentially helping fat loss over time. Any initial weight gain is water in muscle tissue, not fat.
How does it compare to other brands?
Optimum Nutrition is known for strict quality testing and consistency. Their micronized formula typically mixes better than generic brands. Independent testing organizations like Labdoor have consistently ranked Optimum Nutrition Creatine highly for purity and accuracy.

Getting the Best Results with Optimum Nutrition Creatine
To maximize your results:
Food Combinations
- Take with carbs: Research suggests taking creatine with carbohydrates may help it get into muscles better.
- Protein pairing: While not required, taking creatine with protein may be convenient and support overall muscle building.
- Drink enough water: Increased water intake (at least 8-10 glasses daily) helps the creatine work better.
Training Adjustments
Modify your workouts to use the benefits of creatine:
- Do more sets: With better recovery between sets, try adding 1-2 extra sets to exercises.
- Increase weights gradually: As strength increases, slowly increase weights.
- Focus on big exercises: Exercises like squats, deadlifts, and bench press benefit most from creatine.
Possible Side Effects and How to Avoid Them
Most users experience no side effects from Optimum Nutrition Creatine. Some occasionally reported effects include:
- Stomach discomfort: Taking smaller doses throughout the day can help. The micronized form is designed to reduce this issue.
- Dehydration: Creatine pulls water into muscles, so staying well-hydrated is important.
- Muscle cramps: Usually related to not drinking enough water rather than the creatine itself. Proper hydration can prevent this.
- Weight gain: This is mostly water weight in muscles and actually helps performance. It’s not fat gain and typically amounts to 2-4 pounds.
