What is creatine and what is it for?




Creatine is a natural chemical compound that our body is capable of metabolizing through the joint action of certain amino acids, being responsible for synthesizing it by vital organs such as the liver, pancreas and kidneys. Our own body generates a minimal amount of creatine, which is stored mainly in the muscle and brain tissues . That amount is insufficient for the development of our vital functions, so we obtain what we lack through the intake of foods that can provide it, which are mainly meat and fish.

In addition, creatine can also be taken in supplements or food supplements that can be of great help in certain circumstances, such as deficiency states derived from some pathology, and in cases in which extra doses may be necessary, especially when performing an activity. intense sports.




In general, the benefits of creatine in relation to physical exercise are sufficiently contrasted, especially in sports activities that involve explosive or high-intensity exercises that require great effort in a short period of time and, therefore, generate a high demand for Energy. In this sense, creatine supplements provide benefits in sports, but, in addition to sports, creatine can provide other benefits, many of them still pending studies to confirm them.

When and how to take creatine

As we have indicated, the intake of food in a varied and balanced diet provides the creatine that the body needs naturally. When taking creatine supplements, it is always advisable to consult a doctor or nutritionist in advance, to establish its suitability and the appropriate doses.




In general, creatine may be advisable when doing hard training or demanding physical tests. The ideal is to divide your intake into at least 2 shots a day . A good guideline would be, for example, a drink at breakfast (to have extra energy) and another after training, to promote optimal recovery after the effort, although it must be insisted that each athlete (and each person) will have some specific needs that will make creatine intake advisable at a specific time. The important thing to remember is that this supplement should be taken with plenty of fluids ; water, juices, infusions, energy drinks… so that it really promotes muscle development, avoiding dehydration.

Regarding the recommended dose, it will also depend on the characteristics, the physical form and the activity that each person develops, although the general guideline is between 2 – 3 grams/day for a healthy adult who begins taking this supplement . It is important to remember that continuous intake of creatine should not last more than a month. After this time, the body needs a more or less prolonged ‘rest’ before taking it again.
