Because it forms an integral part of the name chosen for our company ‘Phosphore Santé’ [(re)discover why here], phosphorus deserves an article of its own.
Phosphorus is essential to the proper functioning of our bodies, although it is often overshadowed by more high-profile minerals such as calcium and magnesium. Yet its role is just as crucial in keeping us in good health.
Phosphorus is the chemical element with atomic number 15 and symbol P.
It is the second most abundant mineral in the body, after calcium, and is mainly stored in bones and teeth. This mineral is essential for a number of vital biological functions. It is found in the body in the form of phosphate , surrounded by four oxygen atoms.
Phosphorus plays many roles in the body, including the following:
Phosphorus is a key component of bones and teeth. Together with calcium, it contributes to their solidity and structure. A phosphorus deficiency can weaken bones, increasing the risk of fractures and osteoporosis.
Phosphorus is crucial in the production of ATP (adenosine triphosphate), the main source of energy for cells. This molecule is essential for numerous metabolic reactions, supporting all bodily functions, from heartbeat to muscle contractions.
This mineral also plays an active role in the synthesis of nucleic acids (DNA and RNA), the molecules responsible for transmitting genetic information and cell repair. It is therefore essential for tissue growth and regeneration.
The membranes of the body's cells are made up of phospholipid bilayers, and therefore of phosphorus.
Finally, phosphorus plays a role in maintaining blood pH by neutralising excess acid or alkali.
Phosphorus is naturally present in good quantities in many common foods. The main food sources include dairy products, meat, fish and eggs, as well as certain vegetables, wholegrain cereals and seeds (squash, sunflower). For most adults, a balanced and varied diet is sufficient to cover phosphorus requirements.
In conclusion, phosphorus is a mineral that is essential for many vital processes in the body. As well as strengthening your bones and teeth, it plays a central role in energy production and cell repair. Ensuring a sufficient intake of phosphorus is therefore essential for maintaining good overall health.
