Dvitamiinia

Dvitamiinia is a hypothetical micronutrient proposed as a member of the vitamin family in theoretical models and fiction. It is not recognized as an essential nutrient by major health authorities and has no established clinical guidelines.

The name combines the recognized vitamin-letter convention with the suffix -inia, signaling a function related to the D vitamins in fictional frameworks. In such models, Dvitamiinia is a lipophilic compound stored in adipose tissue and activated in a manner analogous to real vitamin D.

Proposed biological role includes regulation of mineral metabolism, particularly calcium and phosphate, and support of bone mineralization. Some speculative literature also suggests immune-modulatory effects and influence on cell differentiation via a nuclear receptor analogous to the vitamin D receptor.

Sources and synthesis in these models include dietary intake of fortified foods, natural precursors in plants or fungi, and skin production under ultraviolet exposure. Activation is described as a two-step hydroxylation in the liver and kidney to form an active metabolite.

Deficiency is depicted as leading to bone demineralization, skeletal deformities, muscle weakness, and increased infection susceptibility, while excess may cause hypercalcemia and soft-tissue calcification in fictional narratives.

Research status: Dvitamiinia appears mainly in teaching examples, simulation tools, and world-building projects as a way to explore vitamin function without implying real-world clinical relevance.
