Product Information

One of the longest studies to date — lasting for 4 years — similarly concluded that creatine has no negative side effects ( 19). The human body produces some creatine naturally and it’s also present in some foods such as red meat, but only in small amounts, making supplements a good option for those who train regularly. What forms does creatine come in? Creatine supplementation can increase functionality (e.g., strength, activities of daily living, delay fatigue) and muscle mass in older adults [ 9, 10, 19, 87, 95, 109, 110]. However, the literature indicates that creatine alone (that is, without a concomitant resistance training program) is unlikely to result in substantial gains in muscle strength and functional performance [ 95, 111, 112, 113], although it does improve some parameters of muscle fatigue [ 114, 115, 116]. Likewise, most studies failed to show a beneficial effect of chronic creatine supplementation alone (≥ 30 days) on lean mass [ 98, 99, 113, 114]. For instance, we recently showed that creatine supplementation was not able to increase lean mass in postmenopausal women who supplemented with creatine (3 g/day) for 2 years, suggesting that creatine supplementation without exercise may be ineffective to prevent sarcopenia [ 99]. It is likely that increases in lean mass occasionally attributed to creatine supplementation in short-term studies (e.g., 7 days) are explained by increased body water, since creatine is osmotically active and it can sometimes induce water retention.

Creatine may also play a role in heart health. Creatine supplements have been studied as a way to improve heart muscle strength, body weight and endurance in patients who survive heart failure. Creatine may help curb high cholesterol, lower triglycerides (fats circulating in the bloodstream) and lower homocysteine levels, which are associated with heart problems and stroke. A person undergoing a creatinine test should let the doctor know if they are taking any medications, fasting, or adhering to a protein-rich diet. In 1998, a case study of a young male with focal segmental glomerulosclerosis and relapsing nephrotic syndrome was reported [ 51]. The young male, who had kidney disease for 8 years and was treated with cyclosporine (i.e., immunosuppressant) for 5 years, had recently begun ingesting creatine supplementation (15 g/day for 7 days; followed by 2 g/day for 7 weeks). Based on increased blood levels of creatinine and subsequent estimate of calculated creatinine clearance, his kidney health was presumed to be deteriorating, although he was otherwise in good health. The patient was encouraged to discontinue creatine supplementation. At this time, it was already known that blood and urine creatinine levels can increase following ingestion of creatine containing food products, including creatine supplements [ 35]. This was ignored by the authors of this case study, as was the inclusion of two investigations which demonstrated that creatine supplementation did not negatively impact renal function [ 52, 53]. The dosage of creatine during the maintenance phase, which was also ignored, was only slightly higher than the daily creatine intake of a typical omnivore’s dietary intake, or in terms of food, a large hamburger or steak per day (meat contains about 0.7 g of creatine / 6 oz. serving; see [ 54]). In response to this case study, two separate teams of experts in creatine metabolism wrote letters to the editor of Lancet [ 53, 55]. However, the notion that creatine supplementation leads to kidney damage and/or renal dysfunction gained traction and momentum.

Creatine does show promise in athletic training, particularly for high-intensity movements such as sprinting, studies show. For example, a 2013 study of 16 amateur swimmers found that those who took creatine supplements had a lower heart rate and blood lactate levels (a measure of tired muscles) after swimming sprints compared with athletes who took a placebo. These results were measured after the participants took the supplements for six days, according to the paper published in the Journal of Sports Medicine and Physical Fitness. Some small studies have shown creatine increases lean muscle mass, strength and speed. Creatine. Natural Medicines. https://naturalmedicines.therapeuticresearch.com. Accessed Nov. 13, 2020. Based on the current evidence, creatine does not cause dehydration or cramping. If anything, it may protect against these conditions. Summary Some people also confuse creatine with anabolic steroids, but this is yet another myth. Creatine is a completely natural and legal substance found in your body and in foods — such as meat — with no link to steroids ( 15). Creatine is one of the most extensively studied supplements and has been shown to increase physical performance in successive bursts of short-term, high-intensity exercise,’ says Aitken.

I wouldn’t recommend doing anything that would show minimal improvement and possible risk," says Jim King, M.D., president of the American Academy of Family Physicians. "Weigh the negatives and the benefits before you try it."Creatine supplements are likely safe for adults when taken at recommended doses. A review of scientific studies on creatine by the Institute of Medicine (IOM) Committee on Dietary Supplement Use by Military Personnel found that getting five grams of creatine a day (from food or supplements) is probably safe over the long term. However, creatine in very high doses is possibly unsafe and may harm kidney, liver or heart function, according to the NIH. IF YOU’RE LOOKING to gain muscle mass, you’ve probably been advised to do a couple things: lift weights, eat a lot of protein, and start taking a creatine supplement.

Pinto CL, Botelho PB, Pimentel GD, Campos-Ferraz PL, Mota JF. Creatine supplementation and glycemiDiet is important. Since certain meats and seafood have high levels of creatine, vegetarians—i.e., people who don’t eat those creatine-rich foods on the reg—usually see a greater response. Those whose diets are highly carnivorous may see less change.

The symptoms of type 1 diabetes may develop suddenly, but the symptoms of type 2 diabetes tend to present more gradually. You’ll know the powder is of poor quality if it’s hard to dissolve and there’s residue at the bottom of your glass after you drink it. You want the powder in your muscles, not in the glass. If this happens, try a different brand. Some people wrongly claim that creatine is an anabolic steroid, that it’s unsuitable for women or teenagers, or that it should be used only by professional athletes or bodybuilders ( 1). In older adults, creatine may boost brain function, protect against neurological diseases, and reduce age-related loss of muscle and strength ( 48). That said, use caution when it comes to taking creatine supplements if you have a history of liver or kidney concerns. A healthcare professional can help you decide whether taking creatine is right for you. SummaryOne study examined creatine use during exercise in hot weather, which can accelerate cramping and dehydration. During a 35-minute cycling session at 99°F (37°C), creatine had no adverse effects on cyclists, compared with o a placebo ( 8). Dolan E, Gualano B, Rawson ES.
