An organic compound, made from the amino acids arginine, glycine, and methionine, creatine is arguably the most popular and well-known athletic supplement in history. First discovered in 1832 by French scientist, Michel Eugene Chevreul, creatine supplements became available to the general public in the early 1990’s.

Since then, creatine continues to be a “must have, must use” supplement for athletes involved in purely explosive strength and power types of exercise: weightlifters, bodybuilders, track and cycling sprinters, CrossFit athletes, football players, and others. Additionally, for all athletes, including endurance athletes, creatine is a staple during off-season weight training workouts, as its use permits the athlete to do more work during reps or sprints, leading to greater gains in strength, muscle mass and performance.

How Creatine Benefits You

While most people tend to relegate creatine’s use to the types of athletes mentioned above, or during off-season weight training, there are many benefits of creatine that all athletes can enjoy all season long. Creatine is also proving to very much be a “go to” overall health supplement for all people (including older people), athletes and non-athletes alike.

Helps muscle fibers heal and rebuild stronger post-exercise. As we all know, exercise creates micro-tears in the muscle fibers. During the recovery period, we want these micro-tears to heal and become stronger. Creatine (protein as well) assists in this all-important process as it helps activate satellite cells— specialized stem cells located within skeletal muscles—which help the micro-tears heal.

Helps reduce exercise-induced soreness. In one study involving well-trained runners competing in a 30k race, the researchers looked at inflammatory and muscle soreness markers—creatine kinase, lactate dehydrogenase, prostaglandin E2, and tumor necrosis factor-alpha—in the runners prior to and after the race. In the control group (no creatine) all the runners had sizable increases in all four inflammatory and muscle soreness markers, while the creatine-supplemented runners had significantly lower levels of all four markers. The researchers concluded, “These results indicate that creatine supplementation reduced cell damage and inflammation after an exhaustive, intense race.”

Has antioxidant properties. Research has shown that creatine increases the activity of antioxidant enzymes and has the capability to eliminate reactive oxygen species (ROS) and reactive nitrogen species (RNS) free radicals. Creatine protects two different and important cellular targets, mitochondrial deoxyribonucleic acid (mtDNA) and RNA against oxidative damage. In addition, creatine has been shown to cause other related effects that help the cell to survive and function under oxidative stress.

Multiple brain health benefits. The conclusion of a review of numerous brain specific studies with creatine supplementation (“Heads Up” for Creatine Supplementation and its Potential Applications for Brain Health and Function), states: “Creatine supplementation can increase brain creatine content, which over time may help explain some of the promising effects on measures of brain health and function. Specifically, creatine supplementation has been shown to improve measures of cognition and memory (primarily in aging adults) and decrease symptoms of sleep deprivation in human and animal populations. Creatine supplementation also shows promise for alleviating some symptoms of TBI (Traumatic Brain Injury), including concussion, and characteristics of muscular dystrophy in humans. The efficacy of creatine for treating symptoms of depression and anxiety is also encouraging but clinical trials examining the effects of creatine (independent of pharmacological interventions) on these mood disorders are needed before a consensus can be reached.”

Cardiovascular health support. While studies on creatine’s effects on healthy human hearts are still ongoing, in animal studies, creatine supplementation restored ATP levels in animals subjected to energy-reducing cardiac stress, while also reducing markers of heart muscle exhaustion. This beneficial effect was also seen in unstressed animals. Studies on humans with chronic congestive heart failure have shown that creatine supplementation increases creatine phosphate levels in their muscles, thus allowing them to perform significantly better on strength and endurance testing compared to those not supplementing with creatine.

Protection against age-related decrease in muscle mass and strength, and bone mass, aka sarcopenia. The abstract of a study (Effectiveness of Creatine Supplementation on Aging Muscle and Bone: Focus on Falls Prevention and Inflammation) states: “Sarcopenia, defined as the age-related decrease in muscle mass, strength and physical performance, is associated with reduced bone mass and elevated low-grade inflammation. From a healthy aging perspective, interventions which overcome sarcopenia are clinically relevant. Accumulating evidence suggests that exogenous creatine supplementation has the potential to increase aging muscle mass, muscle performance, and decrease the risk of falls and possibly attenuate inflammation and loss of bone mineral.”

How to Take Creatine

More and more people over 50 are discovering what science has confirmed for decades: This supplement fights sarcopenia, improves cognition, supports cellular energy levels, and protects the muscle mass that aging insists on stealing. But what few people realize is that taking creatine the wrong way is almost as ineffective as not taking it at all.

The problem is that most people start supplementing without truly understanding how it works. The following elaborates on 10 mistakes that 90% of people over 50 make when taking creatine.

Mistake number one, getting scared by the scale at the beginning. When creatine begins to act in the body, it pulls water into the muscle cells in a process called intracellular hydration. This mechanism is central to how the supplement works and represents exactly what you want to happen. Muscles become more voluminous, better nourished, and have greater capacity to produce energy during workouts. Weight gain from creatine is not accumulated fat. It is simply functional hydration of muscle tissue.

Mistake number two, getting worried because of blood test results. Creatine is a natural byproduct of creatine metabolism in the body and is one of the main markers used by doctors to assess kidney function. Under normal conditions, the kidneys filter creatine from the blood efficiently and its levels remain within an established reference range. When you supplement with creatine, creatine levels in the blood can rise mildly to moderately even if your kidneys are functioning in perfect health. A doctor sees the elevated number, associates it with kidney risk, and recommends stopping. Creatine, when used at recommended doses by adults with healthy kidney function, does not cause kidney damage. The increase in creatine in these cases is called a functional elevation, not a pathological one.

Mistake number three, taking insufficient doses out of fear of side effects. Creatine works through progressive muscular saturation. For it to produce real effects on performance, recovery, and the protection of lean mass, the muscles need to reach a minimum concentration level of phosphor-creatine. Doses below three grams daily are unlikely to reach that threshold in adults with average muscle mass. The scientifically supported recommended daily dose is 3 g to 5 g of creatine monohydrate. There is no evidence that doses above 5 g bring additional benefits for most people, and anything below 3 g will likely be insufficient to produce the expected results.

Mistake number four, not increasing your hydration. Creatine and water are inseparable. Since creatine pulls fluids into the muscle cells, fluids have to be increased. After age 50, the perception of thirst naturally decreases due to changes in the hypothalamic mechano-receptors responsible for signaling dehydration. In simple terms, your body starts asking for less water than it actually needs.

Mistake number five, taking it on an empty stomach. This is the most common mistake of all. Many adults over 50 follow intermittent fasting routines or simply have no appetite when they wake up and end up taking creatine alone without any food accompanying it. From a safety standpoint, this causes no problem, but from an efficiency standpoint, it can represent a real loss of potential. Studies on creatine absorption show that the presence of insulin in the blood significantly facilitates the transport of creatine into muscle cells and the main stimulus for insulin release is the ingestion of carbohydrates, and to a lesser degree proteins. Whenever possible, take creatine together with a meal or snack that contains some source of carbohydrate or protein.

Mistake number six, choosing cheap brands without certification. Products without independent quality certification may contain impurities, heavy metals in concentrations above acceptable levels, inconsistent dosages, and cross-contamination with other substances.

Mistake number seven, overdoing it because you feel stronger. When creatine starts to take effect, the feeling is motivating. For someone who had been feeling limited by the natural wear of the years, this improvement can seem like a green light to accelerate much more than they should... and that is exactly where one of the most harmful mistakes you can make lies. Muscles respond relatively quickly to training stimuli and supplementation, but tendons, ligaments, and joint cartilage adapt at a much slower pace. And this creates a window of vulnerability that can result in overload injuries, tendonopathies, and joint pain.

Mistake number eight, using a loading phase when it's not needed. The loading phase, also called the saturation phase, is a strategy that consists of taking high doses of creatine, generally between 15 g and 20 g per day, divided into four to five servings throughout the day during the first 5 to 7 days. The goal is to saturate muscular phosphor-creatine stores more quickly than the conventional maintenance protocol would allow. In theory, this works. In practice, for most people over 50, it is unnecessary and counterproductive.

Mistake number nine, giving up too soon. Creatine is not a stimulant. It does not produce an immediate feeling of energy, focus, or euphoria like caffeine does. Its mechanism of action is fundamentally different. It works at the cellular level, progressively increasing phosphor-creatine stores in the muscles which improves the capacity for ATP during high intensity efforts. This saturation process is gradual and takes time with the maintenance protocol of 3 g to 5 g per day. Complete saturation can take 3 to 4 weeks. Commit to at least four to six weeks of consistent daily use before making any assessment. 

Mistake number ten, using it to replace bad habits. This is perhaps the most philosophical mistake on the list, but also one of the most harmful in terms of real results. Creatine is an amplifier, not a savior. It enhances what already exists. If the foundation is solid, it improves results significantly. If the foundation is fragile, it does not have enough power to compensate for the deficits. Treat creatine for what it truly is, an optimization tool for those who already have a solid foundation of healthy habits. Sleep well, eat enough protein, train regularly, manage stress, and stay properly hydrated. With that foundation in place, creatine can make a real and measurable difference in your quality of life after age 50.
