Not if your kidneys are healthy. Long-term studies up to five years show no kidney damage from creatine supplementation in healthy people. Creatine raises creatinine levels (a metabolic byproduct), which can look like impaired kidney function on a blood test, but the kidneys themselves are not affected. If you have pre-existing kidney disease, consult your doctor.

Creatine myths and safety # Creatine myths and safety: what decades of research actually say Creatine monohydrate has been studied for decades, with long-term safety data in healthy people spanning up to five years of continuous use. The International Society of Sports Nutrition classifies it as the most effective ergogenic supplement available and has published a comprehensive position stand on its safety. Despite this, myths about kidney damage, dehydration and hair loss persist, largely from a combination of outdated case reports, misunderstood mechanism, and internet repetition. Here is what the research actually says. ## The science of creatine myths and safety ### Short answer Creatine monohydrate is one of the most extensively studied supplements in sports nutrition. Long-term studies up to five years show no adverse effects on kidney function, liver function or blood markers in healthy people. The ISSN position stand reviewed the full body of evidence and concluded that intakes of up to 30 g a day for up to five years are safe and well tolerated in healthy people ([Kreider et al., ISSN position stand, 2017](https://doi.org/10.1186/s12970-017-0173-z)). The common concerns, kidney damage, dehydration, cramping, hair loss, are not supported by the evidence. The one genuine caution: if you have pre-existing kidney disease, discuss supplementation with your doctor, because creatine increases creatinine (a kidney function marker), which can confound test results even when kidney function is normal. ### The kidney myth Creatine is metabolised into creatinine, which is filtered by the kidneys and excreted in urine. Creatinine is also the standard blood marker used to estimate kidney function. When you supplement creatine, your creatinine levels rise because you are producing more of it, not because your kidneys are failing. This has caused confusion in clinical settings where elevated creatinine is flagged automatically. The research is clear: in healthy people, creatine supplementation does not impair kidney function. Studies monitoring kidney markers over years of daily supplementation show no deterioration in kidney function, although small rises in blood creatinine are commonly measured, which reflects creatine metabolism rather than kidney damage ([de Oliveira Vilar Neto et al., 2020](https://doi.org/10.1093/toxres/tfaa028)). The exception is people with pre-existing kidney disease, where the kidneys may not handle the increased creatinine load normally. If you have known kidney issues, get medical advice before supplementing. If your kidneys are healthy, the concern is a myth. ### Dehydration, cramping and hair loss Creatine draws water into muscle cells, which led to early speculation that it might cause dehydration or muscle cramps. Controlled studies have found no increase in cramping or dehydration risk ([Dalbo et al., 2008](https://doi.org/10.1136/bjsm.2007.042473)). In fact, some evidence suggests creatine may reduce the risk of heat-related illness in athletes by increasing total body water. The water retention is intracellular, inside the muscle, not subcutaneous bloating. The hair loss concern comes from a single 2009 study in rugby players that found elevated dihydrotestosterone (DHT) levels after a creatine loading phase. DHT is linked to male pattern baldness. That study ([van der Merwe et al., 2009](https://doi.org/10.1097/JSM.0b013e3181b8b52f)) has never been replicated, and no subsequent research has confirmed a link between creatine and hair loss. It remains an unsubstantiated concern from a single unreplicated finding. ### Why pharmaceutical grade matters Creatine monohydrate is cheap to produce, which means quality varies widely. Lower-grade creatine can contain synthesis byproducts including dicyandiamide (DCD), dihydrotriazine (DHT), creatinine and heavy metals. Chief's Creatine Focus+ is pharmaceutical grade, meaning every batch is tested for these contaminants. When you are taking a supplement daily for months or years, the purity of the compound matters. A few dollars saved per tub is not worth accumulating trace contaminants over time. ### How to use it Chief creatine is 3 g in one scoop, taken once a day. Research commonly uses 3 to 5 g a day for maintenance. Timing does not appear to matter; daily consistency does. It dissolves best in a warm drink and can go into water, coffee, a protein shake or a smoothie. A loading phase is optional. Steady daily dosing reaches the same muscle saturation within three to four weeks. Some people notice mild water retention or stomach discomfort in the first week, which usually settles. If you have kidney disease or any other diagnosed medical condition, or you take prescription medication, check with your doctor before starting. Creatine also raises blood creatinine slightly, which can look like a change in kidney function on a blood test, so tell your doctor you take it before testing. None of this establishes that creatine treats or prevents any condition. ## Not suited for Not suited for people with pre-existing kidney disease without medical clearance. Not suited as a substitute for medical advice if you have concerns about your kidney function. The safety record applies to healthy populations using pharmaceutical-grade creatine monohydrate at recommended doses. It does not extend to high doses, adulterated products, or populations with pre-existing conditions. Some people experience transient water retention of 1 to 2 kg when starting supplementation. ## Chief Nutrition products for creatine myths and safety  ### Creatine Focus+ Creatine Focus+: pure micronised creatine monohydrate, no fillers or stimulants, third-party tested.
