Ferritin

Ferritin — is a protein that plays a key role in iron metabolism in the body. It serves as the primary storage form of iron, ensuring its availability for various physiological processes.

Ferritin is found in the cells of the liver, spleen, bone marrow, and other tissues, as well as in the blood, where its level can serve as an indicator of iron stores in the body.

Functions of Ferritin

The main functions of ferritin include:

• Iron storage: ferritin accumulates iron in a safe form, preventing its toxic effects on cells.
• Regulation of iron metabolism: ferritin controls the level of iron in the blood, ensuring an adequate supply for the body’s needs.
• Immune function: ferritin may participate in immune responses, helping the body fight infections.

Normal Ferritin Levels

Normal ferritin levels can vary depending on age, gender, and health status.

On average, for men, ferritin levels range from 20 to 500 ng/ml, while for women — from 20 to 200 ng/ml.

Low ferritin levels may indicate iron deficiency, which can lead to anemia, while high levels may indicate inflammatory processes or diseases.

Causes of Low Ferritin Levels

Low ferritin levels can be caused by various factors, including:

• Iron deficiency in the diet.
• Blood loss (e.g., during menstruation or injuries).
• Diseases affecting iron absorption (e.g., celiac disease).

Causes of High Ferritin Levels

High ferritin levels may be associated with:

• Chronic inflammatory diseases.
• Liver diseases.
• Hemochromatosis — a hereditary condition in which there is excessive accumulation of iron in the body.

Ferritin and the Keto Diet

The keto diet, based on high fat intake and low carbohydrate intake, may influence ferritin levels.

Since the keto diet often includes iron-rich foods such as meat and fish, it may help maintain normal ferritin levels.

Conclusion

Ferritin — is an important protein that helps the body manage iron stores. Maintaining normal ferritin levels is critically important for health, and its levels can be regulated through proper nutrition and lifestyle.

If there is suspicion of iron deficiency or excess, it is recommended to consult a doctor for diagnosis and dietary adjustments.
