The minerals in our diet: sulfur

Sulfur  is essential for life, in fact it is present in our cells. This macromineral is an important component of three amino acids that are responsible for forming proteins as well as the recognized thiamine, as vitamin B1. Sulfur is present in  keratin , which is a protein substance in the skin, nails and hair, it participates in the synthesis of collagen  (an element that holds cells together). The sulfur absorbed by the digestive system being separated from the amino acids that contain it, to later be transported to the bloodstream and to the cells of the body and hair.

Functions it performs:

These are some of the functions that sulfur performs in the body:

  • It is responsible for maintaining the necessary supply of  oxygen in our brain.
  • It collaborates with the liver for a  correct bile secretion.
  • It collaborates with the B vitamins to ensure  the health of the nerves.
  • It is an integral part of the amino acids that help to  build tissues.
  • It is essential for  keratin and collagen to be synthesized.
  • Its role is of relevance in the  respiration of organic tissues.
  • It favors the  transport and balance of other minerals  in the body.
  • It actively collaborates in the treatment of problems that affect the  skin, nails and hair.
  • It is also involved in the  metabolism of lipids and carbohydrates.
  • The correct functioning of insulin The insulin  molecule consists of two chains of amino acids connected to each other by sulfur bridges, without which insulin could not carry out its biological activity.
  • The  synthesis of  important metabolic intermediates , such as glutathione.
  • Vitamin B1 and the  conversion of biotin , which in turn are essential for the conversion of carbohydrates into energy.
  • Detoxification  of the body.


Its deficiency can cause:

Its lack can cause a series of disorders in the body, these are some of them:

  • It can cause some  weakness in the nails, skin and hair.
  • It can have a lot to do with  problems that affect the joints.
  • It prevents our body from being able to  purify itself normally.
  • It can produce an  incorrect bile secretion.
  • It can produce  alterations of the nervous system.
  • It can cause an  imbalance  in our body  of other minerals.
  • It can cause growth retardation due to its relationship with protein synthesis  .
  • Alterations in lipid and carbohydrate metabolism may occur  .


Precautions and data to take into account:

Its excess can cause  mild diarrhea.

Sulfur can be found frequently in nature in the form of sulfides. During various processes, sulfur bonds harmful to animals and humans are added to the environment. These harmful sulfur bonds are also formed in nature during various reactions, especially when substances that are not naturally present have been added. Sulfur compounds have an unpleasant odor and are often highly toxic. In general, sulfurous substances can have the following effects on human health:

  • Neurological effects and behavioral changes
  • Impaired blood circulation
  • Heart damage
  • Effects on eyes and sight
  • Reproductive failures
  • Damage to the immune system
  • Stomach and gastrointestinal disorders
  • Damage to liver and kidney functions
  • Hearing defects
  • Hormonal metabolism disturbances
  • Dermatological effects
  • Asphyxia and pulmonary embolism



The recommended daily dose is not stipulated, therefore a regulated diet is the only insurance of its correct dose. Although the excessive incorporation of sulfur contained in food is not considered toxic, the ingestion of inorganic sulfur through products not recommended by medical professionals is dangerous.

Its excess is eliminated by the body through urine.

Synergistic nutrients:

Its combination with this group, and more with vitamin B1; enhances its effect:

  • Group B vitamins.

Foods rich in Sulfur:

Here are some of them:

Dried beans and other legumes, garlic, hazelnuts, onion. Brussels sprouts, kale, asparagus, dried fruit, beans, wheat germ, sprouts
