What is BioCeuticals D3 + K2 Spray and who is it for?
BioCeuticals D3 + K2 Spray is an oral liquid combining cholecalciferol (vitamin D3) and menaquinone-7 (vitamin K2 as MK-7) in a convenient spray format. It delivers both nutrients in a single daily dose, making it a practical option for people who prefer liquids over capsules or tablets, or who need flexibility in how they take their daily vitamins.
This formulation suits people focused on bone health, teeth mineralisation, and healthy cardiovascular system function as part of their daily routine. The spray format is straightforward to use and easy to adjust dose by dose as directed by a healthcare professional.
Fairfield Nutrition Thoughts
Vitamin D3 and K2 are frequently considered together because they share relevance to bone mineralisation and healthy cardiovascular system function, and BioCeuticals has a long track record of formulating to practitioner standards. The spray format makes dose flexibility straightforward without requiring a healthcare professional to recount capsules, and the 50 mL bottle provides a meaningful supply at the stated concentrations of 0.1387 mg cholecalciferol and 250 mcg menaquinone-7 per mL. BioCeuticals is a well-regarded Australian practitioner brand, and this formulation reflects their consistent approach to combining nutrients with overlapping indications in a single, practical delivery format.
Why This Formulation / How It Works
Cholecalciferol (Vitamin D3)
Cholecalciferol is the form of vitamin D produced in skin exposed to sunlight and the form found in animal-source foods. Each mL of this spray contains 0.1387 mg of cholecalciferol. Vitamin D3 supports healthy immune system function, helps maintain bone mineralisation, supports bone strength, and maintains healthy cardiovascular system function.
Menaquinone-7 (Vitamin K2 as MK-7)
Menaquinone-7 is a long-chain form of vitamin K2. Each mL of this spray contains 250 mcg of menaquinone-7. Vitamin K2 supports bone health, aids healthy bone development and growth, and helps maintain teeth mineralisation.
Oral Liquid Spray Format
The spray format delivers both active ingredients as an oral liquid, allowing the dose to be measured in mL and adjusted as directed by a healthcare professional. The 50 mL bottle provides a practical supply for ongoing daily use.
