Creatine is a compound that is naturally produced by the human body and can also be obtained from protein-rich foods like meat, fish, and cow's milk. It is a popular supplement used to increase muscle mass, strength, and exercise performance. While creatine is not a steroid or testosterone booster, it is important to note that its long-term use as a supplement has not been extensively studied. Creatine supplementation is allowed by sports organizations and is commonly used by athletes to enhance their physical performance. It may also have therapeutic benefits for certain health conditions, such as improving muscle function in fibromyalgia patients and potentially attenuating brain atrophy in HD patients. Additionally, creatine may be useful for individuals following an energy-restricted diet as it can help maintain muscle mass and promote fat loss. However, it is always recommended to consult a healthcare provider before taking any supplements to ensure they are safe for your individual needs.

What You'll Learn
Creatine is a compound that your body naturally makes
Creatine is also obtained from protein-rich foods such as meat, seafood, and cow's milk. Vegetarians, who may not obtain enough creatine from their diet, can take creatine supplements to increase their intake. Creatine monohydrate is the most common and well-researched supplement form and is supported by hundreds of studies. It is also the cheapest, most effective, and safest option.
Creatine supplements are often used by athletes to increase strength, improve performance, and aid in recovery. Creatine aids in the production of adenosine triphosphate (ATP), which is a source of energy that muscle cells use during exercise. While creatine supplementation does not directly build muscle, it can help maintain muscle mass and promote fat loss when combined with resistance training and a well-balanced diet. This makes it a useful strategy for managing adult-onset obesity and age-related sarcopenia, or loss of muscle mass and power.
Some research also suggests that creatine supplementation may have therapeutic benefits for certain health conditions. For example, it may help improve muscle function in fibromyalgia patients and attenuate brain atrophy in patients with HD. Additionally, creatine may reduce symptoms and slow the progression of some neurological diseases, although more research is needed in this area.

Creatine is found in protein-rich foods like meat and seafood
Creatine is a naturally occurring compound in the human body. It is produced by the liver, kidneys, and pancreas and is found in muscle cells, where it helps produce energy for the body. It is also an amino acid (a protein building block) that can be sourced from certain protein-rich foods.
Creatine is found in meat, seafood, and poultry. Fish, cows, pigs, and chickens store over 90% of their creatine in their muscle tissue. The amount of creatine in seafood and meat varies by species, with some fish, such as herring, containing more creatine. Cooking can cause a decrease in creatine content, and the longer the cooking time, the greater the decrease. However, a good amount of creatine moves to the juice of the meat during cooking, so it may be beneficial to use this juice in a sauce or pour it over the meat.
Meat is the main natural dietary source of creatine, which is why vegetarians tend to have lower creatine stores. For those who don't eat meat, vegetarian sources of creatine include dairy products such as milk and cheese, while vegan sources include seeds (pumpkin, sesame, and pistachio), spirulina, seaweed, watercress, and spinach.
Creatine supplements are also available and are often used by athletes to boost muscle growth and recovery and improve exercise performance. However, it is recommended to speak with a healthcare provider before taking any supplements.

Creatine supplements are used to increase muscle mass and strength
Creatine is a compound that your body naturally produces in the liver, kidneys, and pancreas. It is also found in protein-rich foods, particularly meat. As such, vegetarians and vegans tend to have lower creatine stores and may benefit from taking creatine supplements.
Creatine is a popular supplement used to increase muscle mass and strength. It is the most effective supplement for increasing muscle mass, with research showing that it can double your strength and lean muscle gains compared to training alone. It does this by causing changes within muscle cells, signalling your body to build new muscle proteins. Creatine is also one of the few supplements proven to increase power. One study found that it improved cycling sprint performance by 17% and increased bench press 1-rep max by 18 lbs (8 kg). Another study found that it added 5.7 lbs (2.6 kg) of muscle mass, 24 lbs (11 kg) to the bicep curl, and 70 lbs (32 kg) to the leg press (1-rep max).
Creatine is also beneficial for women, helping them to tone up and increase strength. One study found a 60% greater increase in lean mass in women taking creatine compared to a group that only strength-trained. Additionally, a review of over 150 studies reported an average 2.2% increase in lean body mass and a 3.2% decrease in body fat for those taking creatine.
Creatine is also used to improve performance and speed up recovery from intense exercise. It is a natural energy source for muscle contraction, helping to maintain a continuous energy supply to the muscles during intense exercise. It does this by increasing phosphocreatine levels, which increases ATP (adenosine triphosphate) energy production. ATP is the most basic form of energy in body cells and is a key fuel source for high-intensity exercise.

Creatine may be unsafe for people with kidney disease
Creatine is a compound that the body naturally produces in the liver, kidneys, and pancreas. It is also found in protein-rich foods. Creatine supplements are commonly used to increase muscle mass, boost strength, and enhance exercise performance. While creatine is generally considered safe for most people, there may be risks associated with creatine use for individuals with kidney disease.
Creatine supplements may transiently raise serum creatinine levels, which could be misinterpreted as a sign of kidney disease. This is particularly true if the individual is also consuming a high-protein diet, as this can further increase blood urea nitrogen levels, leading to potential overdiagnosis of chronic renal failure. Therefore, it is recommended that individuals with chronic kidney disease or those taking potentially nephrotoxic medications avoid creatine supplements.
Additionally, there have been rare reports of rhabdomyolysis (breakdown of skeletal muscle tissue) and sudden kidney failure in individuals taking high doses of creatine for extended periods. One case study described an athlete who consumed more than 10 grams of creatine daily for six weeks and experienced these adverse effects. As a result, it is generally advised that individuals with kidney disease, high blood pressure, or liver disease refrain from taking creatine supplements.
While creatine is generally well-tolerated, it is always advisable to consult a healthcare provider before taking any dietary supplements, especially for those with pre-existing medical conditions. Further research and longer-term studies are also warranted to comprehensively understand the effects of creatine supplementation on kidney function.

Creatine may help treat high blood sugar and heart disease
Creatine is a popular supplement used to increase muscle mass, boost strength, and enhance exercise performance. It is also one of the cheapest and safest supplements available. It is naturally found in foods like red meat and fish, and it can also be taken as a dietary supplement, with the most common and well-researched form being creatine monohydrate (CM).
Creatine may help treat high blood sugar by improving glucose metabolism and increasing insulin sensitivity. Research suggests that creatine can increase insulin sensitivity and induce glucose uptake by muscle cells, which can lead to lower blood sugar levels. This effect is more pronounced when creatine is combined with other glucose-lowering medications or exercise. However, it is important for diabetics to be cautious when taking creatine as it can increase water retention and dehydration, and may affect the body's response to insulin. Diabetics should closely monitor their blood glucose levels and may need to adjust their medication dosages when taking creatine.
Creatine may also help treat heart disease, particularly cardiovascular disease (CVD). CVD is a common condition that affects approximately 120 million Americans and can result in significant healthcare costs. Creatine supplementation has been shown to positively affect vascular parameters of arterial stiffness and atherosclerosis in older individuals, which may offer clinical benefits in the management of CVD. Additionally, creatine supplementation has been found to reduce chronic inflammation and improve control of hyperglycemia and dyslipidemia, which are risk factors associated with the development of CVD.
Further research is needed to confirm the efficacy of creatine in treating high blood sugar and heart disease, particularly in the form of larger, longer-term, controlled trials. However, the existing evidence suggests that creatine may offer potential therapeutic benefits in these areas.
