This novel idea has created a massive following of buffered creatine users all over the world! Instagram , YouTube. Creatine is undoubtedly one of the most renowned and widely utilized supplements in the history of our industry. In scientists determined the average human body contained about grams of creatine, of which 95 percent was found to be stored in muscle tissue.
Then, in , the first known scientific study was published in the Journal of Biological Chemistry discussing how creatine promoted weight gain and increased nitrogen balance.
In the late s, Dr. I remember I used to cycle it on and off throughout the year but now I take it basically year round without issue. Like you I see no issue with it, but an interesting counterpoint was put to me recently after a friend listened to the World of Muscle podcast on supplements. Essentially the idea is that if these supplements are taken in isolation, they may deplete the body of other nutrients as these nutrients are used up to digest the artificial supplements.
Excuse the pun, but food for thought! So what is creatine and where did it come from? By it was clear to scientists that Creatine worked From to experiments with animals helped uncover the muscle-enhancing effects of creatine. Like this: Like Loading Other Posts You May Enjoy.

Pingback: What is Creatine? Pingback: Creatine - Adamant Fitness. Some young athletes may not recall the controversy that surrounded creatine in the late s, when the substance was briefly implicated -- though later found not to be a factor -- in the deaths of three college wrestlers.
Thousands of young athletes across the country have decided that a substance that promises to give them a competitive edge -- on the field and, for some, in the chase for a college athletic scholarship -- is worth it, even if it means bending the rules. In recent years, any concerns over creatine have been overshadowed by the controversy over steroids, an illegal substance, and ephedra, an herbal supplement that was legal until the federal government banned its sale earlier this year after linking its use to more than deaths.
Although ephedra and steroids have received most of the attention, school officials, medical researchers and amateur and professional athletes have quietly debated the use of creatine, which has continued to rack up strong sales. With its benefits well-established and potential dangers merely anecdotal, creatine has become the table salt of the performance-enhancement world. Among sports supplements, only protein powder is more popular.
Creatine supplementation began several decades ago in the Soviet Union and gained worldwide attention in , when several British Olympians used it during the Barcelona Summer Games. The same year, researchers in Sweden reported in the British medical journal Clinical Science that creatine supplements could indeed increase muscle creatine levels.
Former St. Days before boxer Oscar De La Hoya fought Felix Trinidad in , a public relations photo of his favorite supplements showed a bottle of creatine. In , however, three college wrestlers enrolled at three universities died within a six-week span while on crash weight-loss diets.
When autopsies determined all three athletes had been using supplemental creatine, which promotes weight gain, the FDA vowed to investigate its role in the fatalities. A review by the federal Centers for Disease Control and Prevention found that exercise in high temperatures and severe fluid restriction had caused lethal hyperthermia and vascular collapse in each of the wrestlers.
Creatine was not a factor, the researchers found. Other alarms were raised. A case study published in the New England Journal of Medicine in told of a year-old man who suffered kidney trouble one month after going on creatine, and then recovered after he stopped using the supplement. Media coverage of creatine quickly soured. Scientists have performed hundreds of studies, some following creatine users for as long as five years; none have found convincing evidence linking it to heart attacks or any other ill effects in healthy people, said Jeff Volek, an assistant professor of kinesiology at the University of Connecticut.
The significance of creatine supplementation and the subsequent increase in muscle and athletic performance must first be prefaced with an introduction to some general metabolic concepts. Many metabolic processes in the body, such as the ones involved in sprinting and weightlifting, have energy requirements. Essentially, ATP is the money that employees, the chemical reactions, are compensated with.
ATPs unique capacity as a vehicle for energy transfer can be explained by its molecular structure. ATP is a molecule consisting of an adenine, ribose, and most importantly, a triphosphate unit. The bonds between the phosphate groups store large amounts of energy and are what makes ATP so effective. When a chemical reaction demands it, one phosphate bond is cleaved in ATP and energy is released, driving the chemical reaction to proceed.
The symbol indicates that this reaction can occur in two directions and is dependant on the amounts of each of the components in the reaction. Hydrolysis, the insertion of water into ATP, causes the release of three components: adenosine diphosphate ADP , which is ATP without one phosphate group, inorganic phosphate P i , the one phosphate group that is released during the reaction, and energy, which is utilized by the cell.
ATP is generated by various metabolic processes in the mitochondria and is used at various sites throughout the cell. Using an elevator is no hassle, but hiking up the stairs does require work much like a chemical reaction that requires an input of energy.
So where does this energy to hike up the stairs come from? What food does for hiking up the stairs is what ATP does for causing chemical reactions to occur. In reality, skeletal muscle only stores enough ATP to power a couple seconds worth of high-intensity exercise.
As a result, ATP needs to be either replaced or resynthesized on an ongoing basis in muscle. Creatine can replenish these stores of ATP, and that is the basis for why it is used as a supplement. Creatine can be phosphorylated in a similar way to ADP. The process is mediated by an enzyme called creatine kinase. Since ATP is limited in the cell, creatine acts as a holder for high-energy phosphate groups similar to a bank account.
Creatine phosphate, however, migrates to muscle fibres. As ADP is generated from muscle contraction, creatine phosphate regenerates ATP allowing for further contraction according to the following reaction:.
