Vitamin K1 (Phylloquinone)

Phylloquinone is the primary dietary form of Vitamin K, found naturally in green leafy vegetables and also produced synthetically for supplementation. It plays a fundamental role in the activation of proteins involved in blood coagulation and bone mineralisation. As a fat-soluble vitamin, it requires dietary fat for optimal absorption, which is relevant when formulating gummies with lipid-based carriers.

Brands choose phylloquinone for its well-established safety profile, low cost, and strong consumer recognition. It is a staple ingredient in bone health and daily wellness formulations, often paired with Vitamin D3 and calcium. Its neutral taste and heat stability make it particularly well-suited for gummy manufacturing.

Origin and history

Vitamin K was discovered in 1929 by Danish scientist Henrik Dam, who identified it as a factor necessary for blood coagulation. The name derives from the German "Koagulationsvitamin." Phylloquinone (Vitamin K1) was isolated from alfalfa in 1939, and its chemical structure was elucidated shortly after. It has been used in dietary supplements since the mid-20th century.

Industrially, phylloquinone is produced through chemical synthesis, typically via condensation of phytol with menadione. The synthetic process yields a product of high purity and consistency, which is essential for supplement manufacturing. It is supplied as a viscous oil, often stabilised with antioxidants and encapsulated for use in gummies and other formats.

Scientific overview

Phylloquinone functions as a cofactor for the enzyme gamma-glutamyl carboxylase, which activates Vitamin K-dependent proteins. The most well-characterised of these are clotting factors (II, VII, IX, X) in the liver and osteocalcin in bone. This dual role explains its two authorised health claims: normal blood clotting and maintenance of normal bones. The body stores limited amounts of Vitamin K, making regular dietary intake important.

Bioavailability of phylloquinone is enhanced when consumed with dietary fat. In gummy formulations, the ingredient is typically dispersed in a lipid carrier to improve absorption. The synthetic form (phytonadione) is bioequivalent to the natural form and is the standard used in supplements. Phylloquinone is stable under normal processing conditions and does not degrade significantly during gummy manufacturing.

From a manufacturing perspective, phylloquinone is heat-stable and soluble in the lipid phase of gummy formulations. It does not require special handling beyond standard good manufacturing practices. Its low cost per serving makes it an economical choice for mass-market formulations. The ingredient is compatible with most common gummy excipients and does not interact negatively with other vitamins at typical use levels.

Phylloquinone is a cost-effective and well-recognised ingredient for bone health and daily wellness gummies. Consumer awareness of Vitamin K is high, particularly in the context of bone health alongside Vitamin D and calcium. The ingredient's neutral taste and heat stability make it straightforward to formulate into gummies without flavour masking or stability concerns. Brands targeting older demographics or women's health frequently include phylloquinone in their formulations.

From a formulation perspective, phylloquinone is one of the easiest vitamins to incorporate into gummies. It does not degrade under heat, has no significant taste issues, and is soluble in the lipid phase. The main consideration is ensuring homogeneous distribution throughout the gummy batch, which is achieved through standard emulsification techniques. Cost is minimal, allowing brands to include meaningful doses without impacting margin.

Pack copy must be disciplined. Only the two EFSA-authorised claims are permitted on EU labels: "Vitamin K contributes to normal blood clotting" and "Vitamin K contributes to the maintenance of normal bones." No disease claims are allowed. Certification status (vegan, kosher, halal) depends on the selected raw material and supplier documentation. DAT confirms certification status per project and batch before final label claims. Shelf-life claims are confirmed per project with stability data.
