The lemon, a fruit characterized by its intense aroma and tart flavor, represents one of the most valuable natural sources of ascorbic acid—commonly known as vitamin C—with concentrations in 100 grams of pulp reaching up to approximately 53 milligrams. While this vitamin remains the predominant nutrient, the fruit’s composition also includes other vitamin compounds, primarily members of the B-complex group—such as thiamine (B₁), riboflavin (B₂), and niacin (B₃)—though their quantities are comparatively modest when set against vitamin C levels. Regarding mineral content, the profile does not exhibit exceptional abundance; however, it does feature trace elements of physiological significance, including copper—essential for proper nervous system and hematopoiesis function—, iron—critical for oxygen transport within the body—, and calcium—a fundamental building block for bones and teeth—even though their concentrations remain at moderate levels.

Lemon fruit is a rich source of vitamin C. In addition to this green product, there are other vitamins, although in small quantities. B vitamins may be mentioned. Also the mineral content is not particularly high. It is primarily copper, iron and calcium. In lemons there are a large amount of bioflavonoids, which affect the functioning of the immune system. Thanks to the externally produced lime, it reduces oxidation and softens the skin. Lemons have an alkalizing effect. That is, they decompose organisms.
