T. J. Clark Liquid  Creatine Sulfate Advanced Formula: 

Half our creatine is created through natural synthesis in our bodies, and half is taken in with food. The creatine is transported through the blood stream, via the liver, pancreas and kidneys to the muscles, where up to 95 per cent of it is stored. The remaining 5 percent assumes vital functions in the areas of the heart, retina and brain. 

For the production of energy our body burns, amongst others, fats and breaks down carbohydrates. This process, called metbolism, releases energy which is stored in the ATP molecule (Adenosine Triphosphate). This energy is absolutely vital for the functioning of the cells in our body. Moreover, muscle contraction is directly linked to the supply of ATP-Molecules. During the contraction, a phosphate molecule splits off. The so-called ADP molecule (Adenosine Diphosphate) remains behind. 

To be able to produce and transfer energy once again, ADP and phosphate molecules must bond with each other again. Creatine binds with the split-off phosphate molecule. Thus, with the help of the enzyme creatine kinase, energy rich phosphocreatine is produced, which is now transported back to the ADP molecule. 

In this way, creatine helps keep our personal source of energy continuously "bubbling over".  

How much energy does a person need? 

Every 154 pounds (70 kg) of body weight contains about 120 grams of creatine. Not all that much for a substance responsible for important bodily functions. On average, 1-2 grams per day are available to us for our "normal" activities. An increased mental or physical load, or stress raises the daily creatine requirement quite significantly. 

About half of our normal creatine requirements are taken in with food. To ensure an optimal formation of creatine, we would have to eat 500g of raw fish or meat every day. Vegetables, fruit and carbohydrates contain only traces of creatine. Thus, those who prefer vegetarian foods or, are on a diet, could have a permanently inadequate provision of creatine. "Feeling low" is thus no surprise in such cases, but rather a logical consequence.  

What is valid for vegetarians, also applies to older people: their bodies show a definite lower storage of creatine. For two reasons:  

1. The capacity for creatine storage drops.. The consequence: a more rapid decrease in performance. 
2. Older people eat demonstrably less. As a result, creatine intake by way of food is reduced. 

Those who wish to retain their performance capacity with increasing age, therefore have a considerably increased
requirement for additional creatine.
