Creatine is one of the most popular and effective sports nutrition supplements. It is commonly used by athletes and bodybuilders to build muscle, increase strength, and improve performance. However, creatine offers a variety of health and cognitive benefits that extend far beyond the gym. Here are 10 lesser known effects of creatine supplementation.
1. Improves Cognitive Function
Creatine is not just for muscle heads. Supplementing with creatine can actually boost brain power and cognitive function.
A study from the University of Sydney found that creatine improved cognitive function in elderly individuals, enhancing both mental and physical performance. Creatine increased brain energy metabolism and improved memory.
Other studies confirm these mental boosts. Short-term creatine use can enhance cognitive tasks like memory, reasoning, and intelligence. This suggests creatine could have wide-ranging positive effects on cognitive ability for people of all ages.
Some research also shows creatine may reduce stress, anxiety, and improve mood and sleep quality by helping the body produce more energy.
2. Strengthens Bones
Creatine increases muscle mass, which can in turn lead to greater bone density. Studies show creatine boosts bone mineral content, important for bone health and strength.
It does this by enhancing calcium absorption and protein synthesis. Both are vital for strong bones.
As we age, bone density declines. Weight lifting is one of the most effective ways to maintain bone density, because the direct pressure and muscle tension triggers bone thickening and strengthening. Amazingly, creatine assists this bone-building process and reduces the risk of osteoporosis.
3. Decreases Inflammation
Creatine lowers levels of pro-inflammatory cytokines like tumor necrosis factor alpha and interleukin-6. It also reduces oxidative stress markers, further cutting inflammation.
One mechanism is creatine’s ability to lower cyclooxygenase activity and inflammatory hormones like leukotrienes and prostaglandins. This antioxidant effect helps prevent chronic diseases tied to inflammation like heart disease, diabetes, cancer, and Alzheimer’s.
4. Reduces Muscle Soreness and Fatigue
By increasing phosphocreatine production, creatine delays fatigue by providing muscles with more energy. It assists in regenerating ATP, the key energy molecule cells use.
Greater phosphocreatine stores allow more ATP synthesis to fuel muscles. Creatine also reduces muscle damage, a primary cause of soreness.
Studies confirm creatine increases muscle creatine content and decreases muscle damage. This speeds recovery from exercise and reduces protein breakdown and soreness.
5. Boosts Athletic Performance
Creatine is most known for improving athletic performance. But this goes far beyond muscle size and strength.
Studies show creatine enhances sprinting, jumping, throwing ability, and more. This directly benefits sports from volleyball to boxing. Increased strength and power advantages athletes beyond bodybuilders.
Creatine also boosts endurance, allowing athletes to perform at peak levels for longer periods before hitting exhaustion. Enhanced reaction times help athletes respond and decide faster under pressure.
6. Increases Water Retention
When creatine enters a muscle cell, it draws water in as well. This cellular hydration is one way creatine builds muscle.
Added water weight places pressure against muscle cell membranes and cytoskeletons. This signals anabolism and increased protein synthesis.
Creatine also raises phosphocreatine stores, which generate more energy and force output by muscle cells. Together, these effects enhance muscle growth.
After a week of creatine loading, expect to gain 1.5-3.5 lbs of water weight. Muscles will look instantly larger and fuller.
7. Assists Diabetes Management
Creatine improves insulin sensitivity and blood sugar control, aiding diabetes management. This is due to increased phosphocreatine production assisting glucose uptake by muscles.
Studies also show creatine boosts insulin sensitivity, helping diabetics better control blood sugar. However, diet and exercise remain the most crucial components of diabetes treatment. Consider creatine an added bonus.
8. Lowers Blood Pressure
Creatine enhances heart muscle efficiency, lowering blood pressure and heart rate because the heart doesn’t have to work as hard. It also improves overall vascular health.
9. Reduces Body Fat
By building muscle mass, creatine raises resting metabolic rate because maintaining all that extra muscle burns additional calories. This stimulates fat loss.
While creatine may increase body weight through water retention, it simultaneously lowers body fat percentage. Remember, fat loss and weight loss are not the same.
Diet mainly drives fat reduction, but creatine’s muscle-boosting and metabolism-enhancing effects contribute as well.
10. Protects Against Neurological Diseases
Creatine may help treat neurodegenerative disorders like Alzheimer’s and Parkinson’s. It also shows promise for Huntington’s disease and traumatic brain injuries.
This neuroprotective ability is linked to increased phosphocreatine in the brain supplying energy. More research is needed, but creatine clearly supports brain function and could contribute to neurological disease treatment.
How Creatine Works Inside the Body
Now that you know some of creatine’s lesser-realized health perks, let’s examine what happens biologically when you take it as a supplement.
Natural Creatine Production
Creatine is produced naturally in the body from the amino acids glycine and arginine. We get these amino acids by eating protein sources like red meat and fish.
But taking supplemental creatine boosts levels far beyond what’s obtained from food or synthesized in the body alone.
Phosphocreatine is a molecule that stores and donates energy to cells, especially muscle cells. Creatine increases phosphocreatine stores, allowing muscles to create more energy and force.
ATP is the key energy molecule that cells use to power biological processes. Creatine enhances ATP synthesis by helping regenerate it. More ATP means more fuel for muscles to contract with intensity.
Drawing Water Into Muscle Cells
As mentioned, creatine pulls water into muscle cells when entering them. This stimulates anabolism and protein synthesis in several ways:
Added cellular hydration places pressure on membranes and cytoskeletons
Increased pressure signals the body to reinforce muscle cells
Reinforcing muscle cells requires increased protein synthesis
More protein synthesis equals more muscle growth
Reducing Protein Breakdown
Creatine lowers muscle cell breakdown by reducing oxidative stress, inflammation, and other catabolic pressures. This preserves existing muscle.
Increasing Protein Synthesis
Greater protein synthesis combined with less protein breakdown is the formula for building muscle. Creatine enhances protein turnover rates to favor anabolism over catabolism.
Additional Keys for Unlocking Creatine’s Muscle-Building Potential
Supplementing with creatine can produce significant muscle and performance benefits. But a few additional factors are needed to maximize its effects.
Creatine works best alongside challenging weight training. The mechanical tension of lifting heavy signals your body to reinforce muscle. Creatine provides raw materials for growth, but tension is the catalyst.
High Protein Intake
Consuming adequate protein is crucial when taking creatine, as amino acids are the building blocks of new muscle. Shoot for around 0.7-1 gram of protein per pound of body weight daily.
Insulin helps shuttle creatine into muscles, so eating carbs can boost results. Try 25-50 grams of carbs an hour before workouts. Post-workout carbs also help.
Drink plenty of water, at least 0.5 ounces per pound of bodyweight. Creatine pulls water into muscle cells, so staying hydrated supports its effects.
Optimal Creatine Supplementation Guide
Follow these research-backed guidelines for the best results from creatine:
Start with a loading phase of 20 grams per day (split into 4 doses of 5 grams) for 5-7 days. This saturates muscles quickly.
After loading, take 3-5 grams once per day. Even just 3 grams maintains saturation.
Take creatine shortly before or after workouts on training days. On rest days it can be any time.
No need to cycle creatine! Stay on it continuously even after loading to maintain results.
Creatine monohydrate is most proven for safety and efficacy. Other forms like creatine HCL are fine too.
Creatine is a safe, natural supplement that builds muscle, fuels athletic performance, and offers widespread health benefits like cognitive enhancement, reduced inflammation, better bone density, and neuroprotective effects.
If you weight train or compete in sports, creatine should be a staple supplement. But anyone can benefit from this versatile compound.
