Supplement companies direct creatine loading when starting. Experts breakdown what creating loading is, whether or not you should do it, and side effects.
This is known as a loading phase and can come with some temporary adverse side effects, like cramping. Creatine supplement plus resistance training yielded the best results.
Experts used to recommend a roughly weeklong “loading phase” in which you consume 20 to 25 grams of creatine daily to “saturate” your muscles before dropping to a lower dose.
After the 5–7 day loading phase, muscle creatine stores are fully saturated and supplementation only needs to cover the amount of creatine broken down per day. This maintenance dose was originally reported to be around 2–3 g/day (or 0.03 g/kg/day), [ 20 ] however, some studies have suggested 3–5 g/day maintenance dose to maintain ...
Creatine-alpha-ketoglutarate is a salt formed from alpha-ketoglutaric acid (AKG) and creatine. Creatine is a mass-produced fitness supplement that is supposed to increase the user's muscle mass, strength and power. Creatine requires a delivery system for cell uptake. [citation needed] An example is arginine alpha-ketoglutarate.
In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. [ 1 ] A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life .
Phosphocreatine can be broken down into creatinine, which is then excreted in the urine. A 70 kg man contains around 120 g of creatine, with 40% being the unphosphorylated form and 60% as creatine phosphate. Of that amount, 1–2% is broken down and excreted each day as creatinine.
The idea of the creatine phosphate shuttle was suggested as an explanation for altered blood glucose levels in exercising diabetic patients. [5] The change in blood glucose levels were very similar to the alterations that would occur if a diabetic patient would receive a shot of Insulin.It was then proposed that contraction of myofibrils during rigorous exercise freed creatine which imitated ...
