About this supplement

Biotin Dicalcium Phosphate is a stable, water-soluble complex combining biotin (vitamin B7) with dicalcium phosphate (a calcium salt of phosphoric acid). This specific chemical form serves as a dual-purpose ingredient in dietary supplements, providing both the essential vitamin biotin and supplemental calcium and phosphorus minerals. The complex enhances stability compared to free biotin and improves mineral bioavailability. Biotin functions as a coenzyme for carboxylase enzymes involved in fatty acid synthesis, gluconeogenesis, and amino acid metabolism. Dicalcium phosphate acts as a source of calcium and phosphorus for bone health and cellular functions. This combination is particularly used in formulations targeting hair, skin, nail health, and bone support.

How much to take

Typical amount
Typically 2,500-10,000 mcg (2.5-10 mg) of biotin component daily, providing corresponding amounts of calcium and phosphorus. Often found in multivitamin or hair/skin/nail formulations.
Suggested range
30-10,000 mcg daily (biotin component); calcium and phosphorus content varies with complex ratio

Technical details â–¼

Formula

C10H16N2O3S·CaHPO4 (complex representation)

Physical properties

Typically appears as a white to off-white crystalline powder. Odorless. Soluble in water (biotin component is water-soluble; dicalcium phosphate has limited solubility). Stable under normal storage conditions. Hygroscopic potential varies with exact formulation.

How it’s made

Produced synthetically through chemical complexation of synthetic biotin (typically manufactured via chemical synthesis starting from fumaric acid or other precursors) with pharmaceutical-grade dicalcium phosphate (produced by reacting calcium carbonate with phosphoric acid). The process involves controlled precipitation or co-processing to form a stable, homogeneous complex.
