What to skip when buying creatine
Skip proprietary blends and multi-ingredient formulas
Many supplements mix creatine with other ingredients like beta-alanine or caffeine in proprietary blends. You cannot verify the exact dose of creatine. Stick to pure creatine monohydrate, which is backed by decades of research.
Avoid flavored creatine
Flavored creatine often contains added sugars, artificial sweeteners, and unnecessary calories. Unflavored powder mixes easily with any beverage and costs less. If you dislike the taste, mix with a flavored drink.
Beware of fancy packaging and high price tags
Some brands charge $50+ for 30 servings, claiming "enhanced absorption" or "premium forms." Creatine monohydrate is the gold standard — no other form has proven advantages. Avoid expensive gimmicks.
Skip products without third-party testing
The supplement industry is loosely regulated. Without third-party testing (NSF, Informed Sport, or independent lab), you cannot guarantee purity. We recommend only brands that provide transparency.
🏆 For Most People: Optimum Nutrition Capsules or Powder
If you prefer capsules: Optimum Nutrition Capsules ($19.99) are convenient and trusted. If you want the standard dose: Optimum Nutrition Powder ($16.00) gives you 5g per serving at a great price.

Frequently Asked Questions
What is the best form of creatine?
Creatine monohydrate is the most researched and effective form. Other forms like creatine ethyl ester or buffered creatine offer no proven advantages and are often more expensive.
How much creatine should I take daily?
The standard dose is 3–5 grams per day. A loading phase of 20g per day for 5–7 days can saturate muscles faster, but it's not necessary. A maintenance dose of 5g daily is effective long-term.
Is creatine safe?
Yes, creatine is safe for healthy individuals at recommended doses. It has been extensively studied for decades. Those with kidney disease should consult a doctor before use.
Should I take creatine before or after a workout?
Timing is less important than consistency. Taking it after your workout with protein and carbs may slightly improve uptake, but the total daily dose matters most.
Do I need to cycle creatine?
No, there is no evidence that cycling creatine is necessary. Continuous daily use is safe and effective for maintaining muscle saturation.
Can women take creatine?
Absolutely. Creatine benefits women by improving strength, lean mass, and exercise performance. Studies show it is safe and effective for both men and women.
What should I look for when buying creatine?
Choose pure creatine monohydrate from a reputable brand. Look for third-party certifications like NSF Certified for Sport or Informed Sport to ensure purity and safety.
