Chronic fatigue, aversion, and susceptibility to infections are symptoms that may be related to a deficiency of this amino acid. The body can produce it on its own, but sometimes it needs much more.
Among the amino acids, it is one of the most important, also due to its role in the body's growth process. Its deficiency can cause lasting negative effects, making it all the more worthwhile to learn what it is and what it does.
What is histidine?
"Relatively exogenous" amino acid - this is how it is defined. In simple terms, this means that although it is produced in the body, only a fully developed adult can produce sufficient amounts. Children and adolescents need additional support in the form of histidine in their diet to be able to function properly. to develop.
Chemically, it is classified as an aromatic and basic amino acid, and importantly, it is a glucogenic amino acid, meaning it can be converted into glucose. It is a precursor to the synthesis of carnosine, which has antioxidant properties, and histamine, which is responsible for wound healing and regulating blood sugar levels. smooth muscle tone. It also participates in hemoglobin synthesis.
What does histidine give us?
Primarily, it is an amino acid essential for the development of a young organism. In infants' diets, histidine supplied through mother's milk allows for proper Metabolism, and therefore weight gain and the proper functioning of all processes. As an amino acid, it participates in the protein formation process, which influences muscle building. In adults, proper histidine levels accelerate recovery after activity and improve performance. When leading an active lifestyle, it's worth paying attention to histidine levels, as they are associated with fatigue.
Histidine also affects the immune system, protecting us against infections and slowing down their development. Its preventive effect on nerve cells and the circulatory system has also been demonstrated. - m.in. in preventing cardiac arrhythmia. Its effect on the digestive system is also important, as it releases gastrin in the stomach, which is responsible for digestive processes and the extraction of nutrients from food.

This amino acid also has properties that protect us from the harmful effects of UV radiation, preventing further damage and the development of skin diseases. It also plays an important role role in cleansing the body of heavy metals such as mercury and lead.
Thanks to its presence, we metabolize trace elements in the body, such as copper, iron, and zinc. It helps form ferritin, iron molecules essential for energy production. Histamine, produced by histidine, plays a crucial role in immune responses, especially in allergies.
What are the effects of histidine deficiency?
Not only does histidine itself have a significant impact on our functioning, but it is also a precursor to many other substances. Its deficiency in the body will therefore have a double impact. on our functioning. It will be most easily noticed by factors such as pale skin, weakness, or anemia. If we are bothered by lethargy, even the slightest physical exertion causes enormous (disproportionate) fatigue, and the energy to act is minimal, it is very likely that we are suffering from deficiency of this amino acid. This can also be seen in the fact that all attempts to rest do not bring the expected results and do not eliminate the feeling of fatigue.
If histidine deficiency will occur during the growth of the organism, it can happen This may manifest as slower weight gain or even stunted growth. It is crucial to monitor the levels of this amino acid during development.
Excess histidine in principle, it is not dangerous for the body, but it may be associated with copper deficiency, the level of which should be monitored should also be observed with longer supplementation. Exceeding the recommended daily doses may cause side effects such as drowsiness or impaired cognitive function. Exceptional The situation is a genetically determined disease called histidemia, i.e., a congenital disorder of histidine metabolism. Patients should closely monitor their histidine levels, especially those obtained from food.
What could be the source of histidine?
Adults primarily benefit from it from food, hence it is important to follow a varied diet. Pork, poultry, eggs, milk and fish are rich in this amino acid.. We will find her too in legumes, bananas, sesame and pumpkin seeds. Histidine supplementation is also possible using preparations available in pharmacies and containing it in their composition: alone or in combination with other amino acids.
Recommended daily doses of histidine have not been determined yet, it is assumed Therefore, this is considered an individual factor. When using dietary supplements, follow the manufacturer's instructions. Although excessive consumption does not cause negative effects, it is worth consulting a doctor before starting supplementation to ensure the recommended dose and the absence of contraindications, such as interactions with medications.
Histidine should not be used by pregnant women, breastfeeding mothers, people with folic acid deficiency, or kidney and liver diseases.
Summary
Histidine is extremely important in early life and during puberty., due to its impact on development. However, its proper levels are essential throughout life, especially when engaging in athletic activity. This amino acid is essential for protein production, blood cell production, and maintaining immunity.
Histidine will help exercisers increase their performance and reduce fatigue, so its deficiency should be supplemented especially by those with above-average activity. Although the adult body has the ability to produce it, supplementation is worth considering in certain cases, remembering that dietary supplements are not a substitute for a well-diversified diet, but merely a supplement.
