What role does ATP play in the body and how can you boost it?

ATP: fuel for cells

Throughout the day, the body needs energy to perform multiple functions. For this, it uses a nucleotide called adenosine triphosphate (ATP), which serves as a kind of fuel for the cell, powering all its reactions (1).

During its hydrolysis, ATP releases one of its three phosphate ions for conversion into adenosine diphosphate (ADP): in doing so, it makes usable energy available to cells. In specific terms, ATP hydrolysis generates between 7 and 15 calories.

Adenosine triphosphate: a source of energy for everything!

While ATP is known mainly in the sports world, where athletes try to optimise the metabolic processes enabling its production, it’s important to understand that adenosine triphosphate is actually crucial for every function in the body.

Digestion, respiration, thermoregulation, maintaining blood concentrations, hormone production, brain function, acting on enzyme mechanisms, etc: ATP is truly multifunctional.

However, the body stores very little ATP, and thus biochemical reactions are constantly being activated to maintain ATP levels (2).

The different mechanisms of ATP synthesis

Aerobic metabolism

At rest, or during low to moderate intensity exercise when energy needs are modest, the body uses oxidation of carbohydrates and fats in the mitochondria (the cells’ ‘powerhouses’) to replenish ATP: this is ATP production by aerobic metabolism (3).

The most efficient mechanism, this can be thought of as a huge reservoir of energy with a low flow, and is therefore the best option for endurance exercise.

Lactic anaerobic metabolism

When exercise intensity reaches a moderate level, cells use glucose to produce ATP. As the intensity of the activity means greater flow rates, the pyruvate and hydrogen ions produced by glycolysis will undergo lactic fermentation, resulting in the production of lactate ions (4).

Alactic anaerobic metabolism

Finally, during short but very intense exercise (sprinting, weightlifting, etc.), it’s alactic anaerobic metabolism which is the preferred mechanism for producing ATP.

This type of metabolism relies on phosphocreatine as the ‘raw material’ for the reaction. However, the body’s phosphocreatine reserves are naturally very low which is why this system is only prioritised for intense but short bursts of exercise: think of it as a tiny reservoir with a huge flow.

Thus a key natural method of boosting ATP production is to engage in regular, moderate exercise. Endurance training (jogging, brisk walking, low-intensity cycling, etc) stimulates aerobic metabolism efficiency and enables ATP to be replenished more quickly and effectively in cells (5).

It’s also important to maintain a healthy and balanced diet sufficient to allow the body to produce ATP.

Supplements that boost ATP production

ATP capsules

For fatigue, loss of concentration and similar issues, you can take ATP capsules!

Adenosine triphosphate can actually be produced in a laboratory in a way that’s completely safe and usable by the body. So if you need to, try taking Peak ATP, a patented ATP formulation.

Creatine

The reason creatine is recognised for increasing performance during successive bursts of short, high-intensity exercise, as well as for improving the effects of resistance training on muscle strength in the over-55s, is precisely because it acts to renew ATP (6-7).

A close relative of amino acids, creatine is involved in cell energy metabolism and is primarily found in muscle and brain cells.

In cells, creatine combines first with a free phosphorus ion, and then - under the effect of the enzyme creatine kinase - this phosphorus ion combines with a molecule of ADP to form a new ATP molecule.

Effectively, therefore, creatine enables ATP to be renewed, hence its ability to increase physical performance during successive short and intense bursts of exercise: in the brief rest phases, creatine helps replenish ATP.

Creatine is therefore another excellent supplement for providing more ‘fuel’ for everyday life!

Additional supplements good for ATP production

We should also mention supplements containing D-Ribose, a major component of ATP (8). L-carnitine, meanwhile, helps transport long-chain fatty acids in the mitochondria to generate ATP (9).
