Frequently Asked About Creatine

How much Creatine should I take?

The typical effective range is 5 g daily. Individual needs vary based on age, body weight, diet, and goals — start at the lower end and adjust based on response. Always consult a healthcare provider before starting a new supplement.

Creatine should be avoided or used with caution by people with None. Pregnant or breastfeeding women should consult a healthcare provider before use.

Compare Forms

5 forms

Different chemical forms vary in absorption, side effects, and best use cases. Higher bioavailability scores indicate better absorption.

Creatine Monohydrate

HIGH 100

Original, most studied form

Best for:Muscle buildingAthletic performanceCognitive function

💡 Excellent. 99%+ absorbed. Gold standard.

✅ Pros

• Most researched
• Most effective
• Cheapest
• Safe long-term

⚠️ Cons

• May cause water retention initially
• Micronized version dissolves better

📝 Best form - no need for fancy versions. Creapure is purest.

Micronized Creatine Monohydrate

HIGH 100

Finely ground creatine monohydrate

Best for:Same as monohydrateBetter mixing

💡 Excellent. Same as regular, just dissolves better.

✅ Pros

• Dissolves better
• Same effectiveness
• Less gritty

⚠️ Cons

• Slightly more expensive

📝 Same as monohydrate, just easier to mix

Creatine HCl

HIGH 85

Creatine bound to hydrochloric acid

Best for:Those with GI sensitivityLower doses

💡 Good. More soluble, may need smaller doses.

✅ Pros

• Very soluble
• Less bloating claims
• Smaller doses

⚠️ Cons

• Less research
• More expensive
• May not be more effective

📝 Marketing claims often exceed evidence

Buffered Creatine (Kre-Alkalyn)

GOOD 80

pH-buffered creatine

Best for:Those who want buffered version

💡 Good. Claims of better stability not proven.

✅ Pros

• pH buffered
• Less bloating claims

⚠️ Cons

• More expensive
• No proven advantage over monohydrate

📝 Research shows no advantage over monohydrate

Creatine Ethyl Ester

GOOD 60

Creatine with ethyl ester attached

Best for:Not recommended

💡 Poor. Converts to creatinine before absorption.

✅ Pros

• None proven

⚠️ Cons

• Converts to inactive creatinine
• Less effective
• More expensive

📝 Avoid - research shows it's less effective than monohydrate

International Society of Sports Nutrition position stand: safety and efficacy of creatine supplementation in exercise, sport, and medicine
Kreider RB, Kalman DS, Antonio J, et al. · 2017 · Journal of the International Society of Sports NutritionPosition standPubMed ↗
Reviews 500+ studies and concludes creatine monohydrate is the most effective ergogenic nutritional supplement for high-intensity exercise and lean body mass, with an excellent safety profile across populations.
Effects of creatine supplementation and resistance training on muscle strength and weightlifting performance
Rawson ES, Volek JS · 2003 · Journal of Strength and Conditioning ResearchMeta-analysisPubMed ↗
Meta-analysis of 22 trials showing creatine + resistance training increased 1RM bench press by ~6.85kg and squat by ~9.76kg vs placebo + training.
Creatine supplementation with specific view to exercise/sports performance: an update
Cooper R, Naclerio F, Allgrove J, Jimenez A · 2012 · Journal of the International Society of Sports NutritionReview
Updates evidence on creatine loading (20g/day × 5–7 days then 3–5g/day maintenance) vs low-dose slow-load protocols, confirming comparable saturation by ~28 days.

More in Performance

Other ingredients in the Performance category.

Agmatine Sulfate

Arginine metabolite with nitric oxide and pain-modulating effects. Enhances pumps.

Arachidonic Acid (ARA)

Omega-6 fatty acid that amplifies exercise-induced muscle signaling. Increases training response but also inflammation.

BCAAs

A branched-chain amino acid blend in a 2:1:1 leucine-to-isoleucine-to-valine ratio, formulated in instantized (micronized) form for improved solubility. BCAAs support muscle protein synthesis and may reduce exercise-induced fatigue, though whole protein sources provide comparable benefits at lower cost.

Beetroot / Nitrates

Dietary nitrates converted to nitric oxide for improved endurance and blood flow. Can enhance exercise efficiency.

Beta-Alanine

Increases muscle carnosine for buffering acid during high-intensity exercise. Delays fatigue in 1-4 minute efforts.

Beta-Hydroxybutyrate (BHB)

Exogenous ketone body that can elevate blood ketone levels. Used for energy, cognitive function, and supporting ketogenic diets.
