Creatine has become popular for its fitness-related benefits, but more research continues to support its other health advantages. Creatine is a natural compound in the body involved in energy production that can also be taken as a supplement.
Sources
Your body automatically makes about 1 gram of creatine every day. Eating foods higher in creatine concentration can help your body maintain these stores. A diet that includes about 1 to 2 grams of creatine daily allows your muscles to reach 60% to 80% of their storage capacity.
Animal-based foods like beef, pork, fish, and lamb are significant creatine sources. A 4-ounce serving of beef (about 1/2 cup ground beef) or salmon has about 0.5 grams of creatine. Dairy products, however, have very little creatine.
Supplements
While creatine is naturally made and found in food, supplements may provide a more convenient and measurable method to increase creatine. Supplements use a concentrated form of creatine to deliver higher amounts. They are usually tolerated well, but, as with any supplement, may have mild side effects. The most common are water retention, or swelling, dehydration, and mild stomach upset. Always consult your healthcare provider or a registered dietitian nutritionist to help determine your nutritional needs.
Deficiency
Individuals at risk for creatine deficiency include vegetarians and vegans, pregnant women, older adults, and those with creatine deficiency syndromes. Research demonstrates that people who eat limited animal-based products like meat and fish have lower muscle creatine levels. Supplementation can improve physical and cognitive performance while maintaining a plant-based diet in these populations.
Women typically have lower muscle creatine levels that could further decline into late adulthood. Sarcopenia is a condition defined by this loss of muscle with age. Increasing creatine may help reduce muscle loss and deterioration for individuals with sarcopenia.
Health Promotion
An abundance of research has explored the health benefits of creatine beyond enhancing athletic performance. Some research suggests that creatine can help lower cholesterol and triglyceride levels, while other studies have found that it can have some antidepressant effects.
Creatine supports energy metabolism in the brain, reducing neuron damage. This could support recovery from a traumatic brain injury. Some studies have even shown that it can support brain health in conditions like Parkinson’s Disease. Specific populations may benefit from increasing creatine intake or supplementation. Research focused on older adults found that creatine supplementation can improve cognitive function while simultaneously increasing strength and muscle mass. It can increase exercise capability for those with cardiovascular conditions and improve metabolism in those with chronic fatigue syndrome.
Takeaways
Creatine is a naturally occurring compound essential for energy production, affecting both physical and mental performance. Supplementation is increasingly supported for the wide range of its health benefits, especially in specific populations like vegetarians and older adults.
