Creatine: The Complete Evidence-Based Guide
Creatine is the most researched supplement in history. Here is what it does, what it does not do, how to take it, and which form to buy.
What Creatine Actually Does
Creatine monohydrate increases the availability of phosphocreatine in your muscles. Phosphocreatine donates a phosphate group to regenerate ATP during high-intensity, short-duration efforts. In practical terms: creatine lets you do 1 to 2 more reps at a given weight, recover slightly faster between sets, and sustain power output for a few seconds longer. Over weeks and months, those extra reps compound into measurably more training volume, which drives measurably more muscle growth.
The effect is modest per session but significant over time. A meta-analysis of 22 studies found that creatine supplementation increased strength gains by approximately 8% and lean mass gains by approximately 14% compared to placebo over training periods of 4 to 12 weeks. This is not a miracle supplement. It is a small, consistent, compounding advantage that works for virtually everyone.
How to Take It
5 grams of creatine monohydrate per day. Every day. With any meal. That is the entire protocol. The loading phase (20 grams per day for 5 to 7 days) saturates your muscles faster but is not necessary. Taking 5 grams daily reaches full saturation in about 3 to 4 weeks. The loading phase just gets you there sooner. If bloating or stomach discomfort is a concern, skip the loading phase and let it build gradually.
Timing does not matter. Pre-workout, post-workout, with breakfast, before bed. The research shows no significant difference in outcomes based on timing. Consistency matters. Take it daily, every day, including rest days. Creatine works by maintaining elevated muscle stores, not by providing an acute effect per dose.
Which Form to Buy
Creatine monohydrate. Not creatine HCL, not creatine ethyl ester, not buffered creatine, not creatine nitrate. Monohydrate is the form used in virtually all positive research. The other forms are marketing differentiation, not scientific improvement. They cost more and do not perform better. Buy the cheapest creatine monohydrate powder from a reputable brand. Look for the Creapure logo if you want verified purity, but generic monohydrate from established supplement companies is fine.
Do not buy creatine gummies, creatine-infused pre-workouts (the dose is usually too low), or creatine in capsules (you pay more for less product). Powder dissolved in water or mixed into a shake is the most cost-effective delivery method by a significant margin. Five grams costs approximately 5 to 10 cents per day with bulk powder. At that price, creatine is the highest return-on-investment supplement you can buy. It is safe, it works, and it is cheap. Take your 5 grams and go train.
