Creatine Monohydrate – What, Why & How

What is Creatine?

Creatine monohydrate is a natural substance formed within the body from the amino acids methionine, glycine, and arginine. It’s stored as creatine phosphate (CP) or phosphocreatine. Creatine phosphate helps make a substance called adenosine triphosphate (ATP). ATP in turn provides the energy for muscle contractions.

The average person’s body contains around 120 grams of creatine. Aside from supplementation, foods such as beef and some types of fish, are fairly high in creatine, but a person would have consume huge amounts on a daily basis to equal what can be found in just one teaspoon of powdered creatine as a supplement.

What is it for?

During short maximal exertion bouts of exercise such as weight training or sprinting,
stored adenosine triphosphate (ATP) is the dominant energy source. It is also the immediate source of energy for muscle contractions. Muscle fibers only contain enough ATP to power a few twitches, then additional ATP must be taken in from the bodys stores. Creatine monohydrate is converted into creatine phosphate in the body to keep the ATP pool filled.
What does this mean in the real world? An increased pool of CP means faster and greater recharging of ATP and, therefore, more work can be performed for a short duration.

The Research – (Excerpt from Will Brinks Bodybuilding Revealed)
To date, research has shown ingesting creatine can increase the total body pool of CP which leads to greater generation of force with anaerobic forms of exercise,
such as weight training, sprinting, etc. Early research with creatine showed it can increase lean body mass and improve performance in sports that require high intensity intermittent exercise such as sprinting, weight lifting, football, etc. Creatine has had spotty results in research that examined its effects on endurance oriented sports such as swimming, rowing and long distance running, with some studies showing no positive effects on performance with endurance athletes.

Whether or not the failure of creatine to improve performance with endurance athletes was due to the nature of the sport or the design of the studies is still being debated. But one thing is for sure; the research is stronger in high intensity sports of short duration.
Recent findings with creatine monohydrate have confirmed previous research showing it’s a safe and effective supplement. More recent research has focused on exactly how it works, and has looked deeper into its potential medical uses.

Several studies have shown it can reduce cholesterol by up to 15%, and
may be useful for treating wasting syndromes such as HIV. Creatine is also being looked at as a supplement that may help with diseases affecting the neuromuscular system, such as muscular dystrophy (MS) and others. A plethora of recent studies suggest creatine may have therapeutic applications in aging populations, muscle atrophy, fatigue, gyrate atrophy, Parkinson’s disease, Huntington’s disease, and other mitochondrial cytopathies, neuropathic disorders, dystrophies, myopathies and brain pathologies.
The importance of creatine is underscored by creatine deficiency disorders: inborn errors of metabolism that prevent creatine from being manufactured. People born without the enzyme(s) responsible for making creatine suffer from a variety of neurological and developmental symptoms which are mitigated with creatine supplementation.
As for safety, some have suggested that creatine might increase the need for extra fluid intake to avoid potential dehydration and muscle pulls. Still, creatine has not been shown to increase either dehydration or muscle pulls in the research.
In some people, creatine may increase a by-product of creatine metabolism called creatinine, which is a crude indicator but not a cause of kidney problems. Some doctors have mistakenly thought that high creatinine levels (in athletes using creatine) are a sign of kidney problems, but that is not the case.
Creatinine is not toxic to the kidneys and most doctors are not aware that creatine may raise creatinine levels with no toxicity to the kidneys. People with pre-existing kidney problems might want to avoid creatine due to the effects it can have on this test, though creatine supplementation has never been shown to be toxic to the kidneys and the vast number, of studies to date have found creatine to be exceedingly safe.

It’s interesting to note that there has been a concerted effort by many groups and ignorant medical professionals to portray creatine as being somehow poorly researched (flatly untrue) and unsafe for long term use. They systematically ignore the dozens of studies that exist showing it’s both safe and effective. Even more bizarre, they ignore the recent studies that are finding creatine may help literally thousands of people with the aforementioned diseases. This is unscientific, unethical, and just plain immoral, in my view.

One question that often comes up regarding creatine is whether or not the loading phase is required. Originally, the advice for getting optimal results was to load up on creatine followed by a maintenance dose thereafter. This advice was based on the fact that the human body already contains approximately 120 grams of creatine (as creatine and creatine phosphate) stored in tissues and to increase total creatine stores, one had to load for several days in order to increase those stores above those levels.
The idea also seemed to work well, in practice, with people noticing considerable increases in strength and weight during the loading phase. All was not perfect however as many people found the loading phase to be a problem, with gastrointestinal upset, diarrhea and other problems. At the very least, loading was inconvenient and potentially expensive.
The need for a loading phase was a long held belief, but is it really needed to derive the benefits of creatine? The answer appears to be no, as both research and real world experience have found the loading phase may not be needed after all. A 1996 study compared a loading phase vs. no loading phase among 31 male subjects.
The subjects loaded for 6 days using 20 g/day and a maintenance dose 2g/day for a further 30 days. As expected, tissue creatine levels went up approximately 20 percent and the participants got stronger and gained lean mass. Nothing new there! And, not surprisingly, without a maintenance dose creatine levels went back to normal after 30 days. Then the group was given 3g of creatine without a loading dose. The study found a similar but more gradual increase in muscle creatine concentrations over a period of 28 days. The researchers concluded:
“…a rapid way to creatine load human skeletal muscle is to ingest 20 g of creatine
for 6 days. This elevated tissue concentration can then be maintained by
ingestion of 2 g/day thereafter. The ingestion of 3 g creatine/day is, in the long
term, likely to be as effective at raising tissue levels as this higher dose.”

A more recent study done in 1999 found that 5 g of creatine per day without
a loading phase in 16 athletes significantly increased measures of
strength, power, and increased body mass without a change in body fat
levels (whereas the placebo group showed no significant changes).
The researcher of this 1999 study concluded:
“…these data also indicate that lower doses of creatine monohydrate may be
ingested (5 g/d), without a short-term, large-dose loading phase (20 g/d), for
an extended period to achieve signifi cant performance enhancement.”
So, if you have suffered through the loading phase in the past thinking it
was the only way to maximize the eff ects of your creatine supplement, it
appears you can rest assured you don’t have to go through all that hassle.
A 3 – 5 gram per day dose over an extended period of time will probably do
the same thing.

Which Creatine is best?

Aside from the obvious price differences, there are also several different types of Creatine in the form of creatine monohydrate, creatine citrate, creatine phosphate, tri-creatine malate, creatine-magnesium chelate and even liquid “ creatine serum”. The newest at the moment being Creatine Ethyl-Ester which is apparently the next best thing. The Problem here is that the overwhelming majority of research to date on the effects of creatine and muscle mass/performance used the monohydrate form and most creatine found in supplements and food is in the monohydrate form.

That fact alone should do it, or the fact monohydrate is the cheapest and easiest to obtain supplement should persuade you away from the lesser tested variations.
Many of these companies try to claim monohydrate is poorly absorbed or that it makes you bloat or hold water – However there is yet to be studies performed side-by-side to compare the differences and the research just simply hasn’t been performed to make these bogus claims. We basically have one of the most researched supplements known to man, shown to be safe, effective and cheap and yet for some reason people are still being drawn toward the new fancy unproven products. I’m not for a moment saying they are not effective, just that they are untested over time. Stick with what we know works!

The Effects Of Alcohol On Building Muscle

After the Christmas/New Year binge, I thought this might be an eye opener!3797775113_9493454735-468x292

Most of us associate the effects of alcohol on the body with the heart, lungs, liver, brain, memory, etc. And when asked about the effects to our training goals, most people will refer to the beer belly.

Drinking a lot of alcohol will cause you to store too many calories as fat. Some people go for low calorie drinks or diet mixers (i.e diet coke) and feel that by making this choice the only bad effects of the alcohol (increased fat storage) will be minimized. The fact is, only about 5% of the calories from alcohol are stored as fat! The effects of alcohol on the body are far more damaging than the number of empty calories in some alcoholic drink.

1: Alcohol really affects the amount of fat your body can and will burn for energy.

In a study done by the American Journal of Clinical Research, It was concluded that just a mere 24g of alcohol consumption showed whole-body lipid oxidation (the rate at which your body burns fat) decreased by as much as 73%!
When alcohol goes through the liver, the by-product is called Acetate. Acetate puts the brakes on fat burning in a massive way. Your body can use many types of fuel. Protein, carbohydrates and fat. In many cases, the fuel used is dictated by its availability, your body will use whatever is available so as your acetate levels increase, your body burns more acetate as fuel. What this means is fat burning takes a back seat. Basically a) You have a few drinks. b) Your liver metabolizes that into acetate. c) Your body uses the acetate for fat as fuel.

2: It leads to an increase in your appetite.

In another American Journal of Clinical Nutrition study, there was evidence to suggest that consumption of alcohol leads to an increase in appetite over that of any other carbohydrate type drink. Researchers over in the Research Department of Human Nutrition and Center for Advanced Food Studies in Denmark concluded that consumption of alcoholic beverages, and wine in particular, may enhance total energy intake at a meal relative to a soft drink, when served with no restriction.

3: It decreases testosterone and increases cortisol levels.

A study of 8 healthy male volunteers observed that after drinking alcohol, the effects of a significant decrease in testosterone and an increase in cortisol (a muscle destroying hormone) lasted up to 24 hours. So if you are serious about building muscle and burning fat, you want all the free testosterone levels you can get and you want to reduce cortisol in any way you can. That means go easy on the booze as it does affect your hormone levels. Worse still the effects are worse if you exercise before drinking – So don’t drink on training days! Not shocking is a study done by the Department of Radiology, Sahlgrenska Hospital, Goteborg, Sweden that determined increased waist to hip ratio of alcoholics may include not only changes in adipose tissue, but also in muscle tissue distribution – Fatter around the middle and less muscle, not ideal!

 4: It decreases vitamin and mineral absorption.

When you consume large quantities of alcohol, your liver is working overtime converting the alcohol to acetate and any vitamins and minerals that it might process are taken up by the detoxification process. Alcohol interferes with the metabolism of most vitamins, and with the absorption of many nutrients. Alcohol stimulates both urinary calcium and magnesium excretion. This just means that you’ll get less of a benefit from the “healthy” meal you may be consuming. Food in the stomach will compete with ethanol for absorption into the blood stream. It is well known that alcohol competes and influences the processing of nutrients in the body.

5: It decreases protein synthesis of type II fibers.

This means the actual building of muscle is slowed down by 20%+ or more. This included a 35% decrease in muscle insulin-like growth factor-I (GF-I).

6: It increases dehydration.

A common side effect of alcohol is dehydration. Alcohol is a diuretic. Drinks containing 4% alcohol tend to delay the recovery process. Considering how important water is to muscle building and general health, it’s clear that dehydration can put a real damper on your progress. After alcohol consumption the first thing you might want to do is drink coffee. But that’s a diuretic as well. How to avoid dehydration? Drink more water!

7: It reduces sleep

Alcohol consumption, especially at the times when you would normally sleep, can have effects on the quality of sleep. Clearly high quality sleep is extremely important to the rebuilding and growth process of muscle. Without proper rest and recovery, your gains will be affected. Alcohol consumption can also induce sleep disorders by disrupting the sequence and duration of sleep states and by altering total sleep time as well as the time required to fall asleep.

8: You won’t make PR’s with a hangover!

Obvious really, but if you plan on drinking on a Friday night in excess then the squat session you normally do on Saturday morning will take a hit. It takes a bit to recover, your body to detoxify and for you mentally to be prepared to workout. Not to mention you need energy for the workout ahead. Sure you can hit the weights but , it’s not going to be a great session.

For more evidence in the November 2004 issue of the International Journal of Obesity a study on the effects of moderate consumption of white wine on weight loss was done. Each group consumed 1500 calories. 150 calories came from white wine in one group and 150 calories from grape juice in another. The conclusion: An energy-restricted diet is effective in overweight and obese subjects used to drinking moderate amounts of alcohol. A diet with 10% of energy derived from white wine is as effective as an isocaloric diet with 10% of energy derived from grape juice. It’s simple: Moderation is the key!

So basically the effects of alcohol on your body when it comes to building muscle and burning fat are quite clear. It is a lot more than just some extra calories stored as fat. If you drink too much, it can upset your goals for a lot longer after your head has hit the pillow and you’ve gone to sleep.
