Creatine 101: Part 1
Every man, woman, and child (without renal implications) should be supplementing with creatine monohydrate alongside their well-rounded diet.
Yes, it is that important. If creatine was ever considered to become a nutrient I would have no problems with it.
It's usages in both athletic and clinical applications has shown consistent promise for the past few decades.
Not only is it the most widely studied supplement in the world, it may also be one of the most comprehensive in terms of benefits to health. The list of benefits is LONG.
Another great feature is that it has virtually NO negative side effects despite what non-credible media sources have said over the years. Most reported issues with creatine likely have to do with the consumer not fully diluting the creatine in solution or potentially not being hydrated in the first place.
So how does it benefit you? Here's a paraphrased list:
• increases muscle strength during training
• increases lean tissue (muscle) from training as a byproduct of increased work output/volume
• may prevent athletic injuries 
• may prevent depression
• may prevent certain forms of cancer due to DNA protection [4,5,6]
• may prevent brain trauma or injury (think about your kids that play contact sports) 
• may be beneficial to select medical conditions (Alzheimer's, Parkinson's, *Huntington's) [9, 10, 11]
• may enhance cognition particularly in vegetarians or omnivores that are creatine deficient [12,13]
Any of these features sound intriguing? By the way, creatine monohydrate is dirt cheap. In this review, I'll discuss the basics of what you need to know on creatine.
What is creatine?
Creatine is an ergogenic aid (performance-enhancing) that is synthesized in the liver and pancreas and is derived from three amino acids: glycine, arginine, and methionine . It is part of phosphocreatine and is used anaerobically to initiate high-intensity activity. However, stored phosphocreatine suffices to support activity for only several seconds and must be resynthesized for use in similar subsequent activities . Creatine is naturally occurring in foods such as meat, fish, and milk.
Creatine Distribution in the Body
Creatine phosphate is broken down via creatine kinase to yield a phosphate group to adenosine diphosphate to make adenosine TRIphosphate again (remember that you need adenosine triphosphate for energy).
OR in equation terms
ADP + CP-->(creatine kinase) -->ATP+ C
I'm a visual person. This chart should help you envision the glory of creatine's works. Below is an example of which energy pathways are being activated by the duration and demand of the event.
The multiple energy pathways operate do not operate alone. They can all be working together at any given moment pending the intensity and duration of the event. For example, imagine pacing yourself on a run when all of a sudden, the finish lines comes in sight.
What happens next? You're picking up the pace! That's when creatine kicks in to help increase power output when you need it most.
Have your lifts in the gym ever hit a plateau? That's an easy job for creatine. I've got a cool story about that for another time!
Imagine this scenario: what if you or your kids play a contact support with the possibility of a traumatic brain injury? There's evidence (7) that creatine could mitigate the damage from a blow to the head.
Convinced yet? Great! You can find some HERE on Amazon and help make my family a small commission from your purchase ; )
