Inosine is a natural element for the human body, and it is directly involved in the vital processes taking place in it. It's found in the skeletal muscle and the myocardium.

Inosine is a purine nucleoside and a precursor to adenosine triphosphate (ATP). ATP is the energy currency of cells, as it is a substance that stores and transfers chemical energy. It is not metabolized, meaning this is a pure, ready-to-use biochemical energy for bodily cells.

ATP transfers energy to the cells, turning into adenosine diphosphate (ADP). The constant levels of ATP in cells is relatively low, being used up in the 1st few seconds of intensive anaerobic exercises.

This means that continued and strenuous training uses up the energy reserves in the body very quickly, leading to fatigue and a drastic drop in efficiency. As such, the body has to constantly produce ATP from fats, glucose and amino acids.

The inosine, in turn, has an excellent antihepatotoxic function, which means it improves oxygen supply to the erythrocytes, while at the same time increasing its absorption by working muscles.


This becomes a key factor in boosting sports performance in sports that are focused entirely on developing endurance.

Benefits of Inosine

Inosine finds application as a crucial cardioprotector in prophylactics of numerous cardiovascular diseases. The high temperatures during the summer months, excessive sweating and increased consumption of liquids make the use of inosine a must. It is superb protector of the cardiac muscle when it is highly strained.

American scientists have proven that inosine can be helpful in the treatment of stroke. It is an effective prophylactic and preventative measure against liver diseases.

Inosine possesses a powerful immunostimulant capability, shortens the duration of certain viral infections, as well as the occurrence of relapse.

Inosine is a high quality food supplement, and when combined with L-carnitine it helps to provide energy to the heart and skeletal muscles, while at the same time boosting endurance.

Many trainers recommend inosine as the perfect stimulant and required supplement for extended and intensive workouts.

Inosine plays an extremely important role for bodybuilders. It plays a direct role in muscle protein synthesis and carbohydrate metabolism.

For this reason, inosine is exceptionally crucial while building muscle mass. As well, it quickly neutralizes accumulated lactic acid, restores tired muscles and enhances the effectiveness of the workout.

Sources of Inosine

The best sources of inosine are brewer's yeast and organ meat, such as animal liver, brain and kidneys. Commercially, inosine is available in the form of dietary supplements - on its own or in combination with other supplements.

Recommended Doses of Inosine

The recommended dose of inosine is 1.5-2 mg before a workout. Since inosine is not an essential nutrient, a person can't have a deficiency of it but those who actively work out do need it.

Dangers of Inosine

In general there are no observable side effects of taking inosine. However, unused inosine in the body is turned into uric acid, which is not good for people suffering from gout. There are no known interactions of the supplement with other medicines.
