The Active Ingredient Is: Bone Support

Bone Support is a dietary ingredient blend that's designed to support normal bone function through a bioavailable mineral and cofactor mix. The formula brings in marine calcium via Aquamin with essential vitamins and minerals to help skeletal processes.

This blend includes bioavailable marine calcium, vitamin D3, vitamin K2 and strontium, sourced to support absorption and integration within the body's natural bone maintenance pathways.

What Does Bone Support Do?

Bone Support participates in normal calcium utilisation and supports the synergy of calcium with vitamin D3 and vitamin K2, which are factors linked to bone health maintenance in scientific contexts. Dr. Kaneki of the University of Tokyo found that absorbable calcium alongside D3 and K2 can influence bone-related outcomes.

By contributing to the body’s mineral balance and cofactor interactions, it helps with mechanisms involved in bone density maintenance rather than delivering a disease-specific outcome, in line with EFSA-style expectations.

This supplement isn't intended to diagnose, treat, cure, or prevent any disease.

The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also called cholecalciferol, is a fat-soluble nutrient important for keeping calcium metabolism and bone health on track.

This version is often supplied as cholecalciferol in supplements and is linked to aiding calcium uptake and delivery to support bone mineralisation.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium uptake and mineralisation in bones, contributing to normal bone function. This input aligns with EFSA guidance on vitamin D and bone health and supports general immune function in line with established recommendations.

By enabling calcium utilisation, Vitamin D3 works alongside other nutrients in bone metabolism as part of a balanced diet.
