CLEVELAND, OH — The large tubs of powdered supplements found in gym lockers and specialty health stores have long been associated with young bodybuilders looking to bulk up. Local medical experts say that is no longer the case. According to Dr. Fred of Cleveland 13, creatine is quickly moving into the mainstream as a tool for healthy aging, women's health and cognitive function. It is not a steroid, a hormone or a stimulant, but rather a compound the body produces naturally and sources from meat and seafood. Most of the body's supply is stored in skeletal muscle to regenerate ATP, which provides the quick bursts of energy needed for sprinting or lifting heavy objects. While researchers have known for decades that the supplement can improve performance during repeated bouts of high-intensity exercise, the focus is shifting toward how it supports the brain's enormous energy demands. Dr. Fred notes that creatine, stored as phosphocreatine, essentially increases the energy reserve available for both physical and mental tasks. This does not mean it acts as a magic pill. To see muscle benefits, a person still has to perform resistance training. The supplement simply amplifies the results of that hard work. This amplification is becoming a critical talking point for the aging population. As people get older, they face sarcopenia, which is the natural loss of muscle mass and strength. This decline can eventually affect a person's ability to climb stairs, carry groceries or catch themselves during a fall. Dr. Fred explains that for a 65-year-old, muscle mass is less about aesthetics and more about maintaining independence. Recent evidence suggests that combining creatine with strength training can help older adults fight back against that physical decline more effectively than exercise alone. The conversation is also expanding to include women, particularly those navigating menopause. Traditionally marketed toward men, creatine is now being studied for its impact on bone health and body composition changes in postmenopausal women. Dr. Fred points to a 2026 systematic review and meta-analysis that examined the effects of creatine monohydrate specifically in this demographic. While some users worry about weight gain, it is often just water retention in the muscles rather than fat. That initial scale increase usually subsides over time. Cognitive health is the latest frontier for this research. The brain is metabolically expensive and requires constant energy to function. Randomized controlled trials have looked at how creatine affects memory and processing speed, with promising results, especially in older adults or during times of high metabolic stress. It is important to note that the supplement is not a cure for dementia, and it will not make a person smarter overnight. Dr. Fred warns that social media influencers often get ahead of the actual science by making "miracle" claims that have not been fully established. Safety remains a top priority for those considering new supplements. A common concern involves kidney health, but Dr. Fred says that for healthy adults using recommended doses, there is no evidence of damage. Confusion often stems from a blood marker called creatinine, which is used to estimate kidney function. Supplementing can sometimes cause a spike in those levels on a lab report without actually causing harm. It is vital to tell your doctor about your supplement regimen so that results can be interpreted accurately. For those interested in trying it, the advice is to keep it simple. Dr. Fred recommends avoiding expensive, "exotic" blends or proprietary versions such as creatine hydrochloride, which he describes as a scam designed to get people to spend more money. Plain creatine monohydrate is the most extensively studied and effective form. A standard dose is 3 to 5 grams per day, and there is no need for a "loading phase" in which high amounts are taken for a week. Consistently taking a small dose will saturate the muscles over time without causing the gastrointestinal issues often associated with higher amounts. While the supplement is not necessary for everyone, especially those with a perfect diet and sleep schedule, it offers a low-cost way to support muscle and brain health. Most people can take it at any time of day, though mixing it with a simple carbohydrate such as fruit juice can help with absorption. Anyone with pre-existing kidney conditions should consult a health care provider before starting a new regimen.
