Is creatine monohydrate just as good as more expensive forms?
Creatine monohydrate works at least as well as more expensive alternatives and is the most thoroughly documented safe choice. Choose monohydrate and skip the expensive variants.
Creatine monohydrate works at least as well as all more expensive variants. That is the short version, and the evidence for it is reasonably strong. A systematic review of 17 studies compared alternatives such as creatine citrate, malate, ethyl ester, nitrate and pyruvate with a placebo. None of those forms consistently outperformed monohydrate for muscle performance or body composition. Only three studies compared an alternative directly with monohydrate, which makes firm conclusions difficult.
If you want to take creatine for muscle strength or lean mass during resistance training, take 3 to 5 grams per day for at least 8 to 12 weeks. Check the label: it should literally say 'creatine monohydrate'. Powder or capsules makes no difference. Whether you take it with carbohydrates does not matter for the muscle effects. A loading dose speeds up the build-up but is not necessary. Whether the brand is expensive or cheap makes no difference either: monohydrate is already the cheapest form.
One variant stands out negatively: creatine ethyl ester. It is converted into creatinine in the gastrointestinal tract. As a result, a blood test may incorrectly suggest that your kidneys are failing. This effect does not occur with monohydrate. Furthermore, in a study of patients with creatine transporter deficiency, creatine ethyl ester did not lead to any measurable improvement in brain function or creatine levels in the brain after twelve months. Creatine ethyl ester is therefore not only no improvement, it has active disadvantages.
At 3 grams per day, creatine monohydrate is considered safe for healthy adults. Known side effects include temporary fluid retention and occasionally gastrointestinal complaints or muscle cramps. At higher doses or in combination with other supplements, cases of liver and kidney problems have been reported: more is therefore not automatically better. For most alternative forms, safety data are scarce and specific concerns have been identified for some. Creatine monohydrate is not worth your money if you buy a more expensive alternative: that alternative has no proven benefit.
Based on a systematic review of 17 RCTs (PMID 36000773), an established consensus source on creatine efficacy (PMID 23851411), a safety review by competent authorities (PMID 28019093), a case report on CEE and creatinine (PMID 21411845), and a small clinical trial in four patients (PMID 19955008).
Do you need to do a loading phase with creatine?
A loading phase is not necessary, but it does speed up the build-up of creatine in your muscles. Choose a loading phase if you want fast results, or simply take 3 to 5 grams daily if you have more patience.
Why don't doctors always recommend creatine?
Creatine monohydrate is well supported for strength sports and its safety profile in healthy adults is reassuring, but safety data for children and teenagers are lacking and some proven applications are more limited than the marketing suggests.
What is best not to combine with creatine?
Combining creatine with caffeine powder adds nothing to your performance and increases the risk of gastrointestinal complaints; ready-made pre-workout blends with many ingredients carry additional risks due to possible contamination and unknown long-term effects.
Does creatine cause hair loss?
Current research shows that creatine does not raise DHT and has no effect on hair follicle health. There is no need to avoid creatine out of fear of hair loss.
What does creatine monohydrate do for your health?
For strength and muscle mass during high-intensity training, creatine monohydrate (3 to 5 g per day) has the strongest evidence base of any dietary supplement. In endurance sports it offers no benefit, and if you have a kidney condition you should discuss its use with your doctor first.
Does creatine work better with carbohydrates?
Carbohydrates probably increase the uptake of creatine into the muscle cell via insulin, but when compared against a placebo in research this does not translate into better performance. Add carbohydrates if you want to load, but do not automatically count on extra training results.
