Creatine is an acid naturally found in the human body that helps to provide energy to the cells. It is found throughout the body, but its primary responsibility is supplying the cells that build muscle and nourish the brain. Scientific studies have shown that human blood is actually made up of one percent of this acid. All vertebrates have creatine in their systems, with the animal kingdom producing higher levels than humans.
The body combines the amino acids glycine and arginine to produce creatine, synthesizing it mostly in the liver and kidneys. It also uses food to produce creatine, mostly when red meat is consumed, since this type of protein provides the body with additional amino acids.
Because of its ability to help the body produce more muscle mass, creatine has become a popular supplement for bodybuilders. These supplements contain high doses of amino acids that help to increase the muscle-building acid in the body naturally. The best creatine supplements are designed to be absorbed into the system faster, and remain longer, to increase the efficiency of each dose. The fast absorption reduces stomach upset, the main complaint of supplement users.
The most valuable trait of creatine is that the body will store excess levels until they are needed. This means that none of the supplement will ever be wasted. When taken regularly, supplements have been shown to make people feel more energized, improve their athletic performance and recover faster from a workout. It can even help to improve mental clarity. Because of the ability of creatine to help glucose metabolize easier, research is currently ongoing to determine the effectiveness of this type of supplement in aiding those with Type 2 Diabetes.
Since the supplements only contain natural amino acids, there are very few worries about side effects. Stomach upset was once common, but advancements in how the product is delivered into the system has eliminated much of that concern. Some individuals have proven to be sensitive to high levels of creatine, leading to asthmatic symptoms. Anyone new to the supplement should be cautious about this type of reaction and avoid taking it if they notice any wheezing or breathlessness.
