First described in the scientific literature in 1950, folinic acid was originally known as the "citrovorum factor" due to its growth-promoting properties in bacteria. This essential compound has since become more commonly known by its pharmaceutical name, leucovorin. Its ability to rescue healthy cells from the damaging effects of certain medications is a cornerstone of modern medical treatments.

According to extensive medical literature, calcium folinate is not the same as folic acid, though both are forms of the essential nutrient vitamin B9. The core difference is their metabolic state, with calcium folinate being an active compound while folic acid is a synthetic form requiring conversion by the body.

According to the National Institutes of Health, delayed administration of leucovorin rescue beyond 40 hours after methotrexate can lead to permanent tissue toxicity. The primary benefit of calcium folinate lies in its crucial role as a detoxifying agent, counteracting the harmful effects of specific chemotherapy drugs like methotrexate.

Folinic acid dosage varies dramatically depending on the specific medical condition, with regimens ranging from prophylactic use to intensive rescue therapy following chemotherapy. Therefore, there is no single answer to how much folinic acid per day is appropriate for every individual.

Folinic acid, an active form of vitamin B9, plays a critical role in cellular processes, including DNA synthesis and repair. Unlike synthetic folic acid, this compound is immediately usable by the body without the need for enzymatic conversion, making it uniquely valuable in various medical treatments.
