In 2024, the EFSA NDA Panel concluded that a cause-and-effect relationship between creatine supplementation and improvement in cognitive function has not been established, noting inconsistent effects at lower doses. In the UK, creatine is generally sold as a food supplement. Manufacturers must ensure any health claims made on packaging or advertising comply with the requirements of the UK Nutrition and Health Claims Regulation (NHCR) and are substantiated to the standards of the Advertising Standards Authority (ASA). The Medicines and Healthcare products Regulatory Agency (MHRA) does not classify creatine as a medicine when marketed as a food supplement for general use.","faqs":[{"question":"Does creatine cause kidney damage?","answer":"Current scientific evidence suggests that creatine supplementation, at recommended dosages, does not cause kidney damage in healthy individuals. While it can lead to a modest, transient increase in serum creatinine levels, this is generally due to its metabolic turnover and not an indication of impaired kidney function. (Kabiri Naeini et al. 2025, meta-analysis; Antonio et al. 2021, systematic-review)"},{"question":"Will creatine make me gain weight or look 'bloated'?","answer":"Creatine can cause an initial increase in body mass, primarily due to increased water retention within muscle cells, especially during a loading phase. This is not typically fat gain. Long-term studies indicate it can increase lean body mass and reduce body fat percentage when combined with resistance training. (Antonio et al. 2021, systematic-review; Pashayee-Khamene et al. 2024, meta-analysis)"},{"question":"Is a loading phase necessary for creatine?","answer":"A loading phase, typically 20g/day for 5-7 days, can rapidly saturate muscle creatine stores. However, a lower daily maintenance dose (e.g., 3-5g/day) will achieve similar muscle saturation over a longer period (around 3-4 weeks). Both methods are effective, with the loading phase simply accelerating the benefits."},{"question":"Is creatine effective for endurance sports?","answer":"Current research suggests that creatine monohydrate supplementation is generally ineffective for improving aerobic endurance performance in trained populations. Its primary benefits are associated with high-intensity, short-duration activities. (Fernández-Landa et al. 2023, meta-analysis)"},{"question":"Are other forms of creatine better than monohydrate?","answer":"Scientific evidence indicates that creatine monohydrate is the most effective and well-researched form of creatine. No other commercially available form has consistently demonstrated superior efficacy or absorption compared to creatine monohydrate. (Kreider et al. 2017, position-stand)"},{"question":"Can creatine help with cognitive function?","answer":"Some research suggests creatine supplementation may offer beneficial effects on certain aspects of cognitive function, particularly memory, with more pronounced benefits observed in older adults.
