Supports is higher

Support is ahead, but a single strong opposing study can change this.

Taking vitamin K2 supplements leads to the activation of vitamin K-dependent carboxylation pathways in humans.

See the scientific wording

Vitamin K2 supplementation activates vitamin K-dependent carboxylation pathways in humans.

Why this might work

Vitamin K2 enters the bloodstream from the gut, travels to bone cells, and helps an enzyme add a special chemical group to a bone protein. This change lets the protein bind to bone minerals and become active.

What the research says

2 studies

  1. Study: The effect of vitamin MK-7 on bone mineral density and microarchitecture in postmenopausal women with osteopenia, a 3-year randomized, placebo-controlled clinical trial

    Taking vitamin K2 supplements helped the body better activate a key bone protein, even though it didn't stop bone density from slowly decreasing over time. The study proves the supplement works at the biochemical level.

  2. Study: The effect of menaquinone-7 (vitamin K2) supplementation on osteocalcin carboxylation in healthy prepubertal children

    Giving kids a daily vitamin K2 pill made a key bone protein work better by activating it — and kids who took a fake pill didn’t change. So yes, vitamin K2 supplements help activate important body processes.
