Raloxifene and Vitamin K2: what the published research says

PubMed indexes 2 records that name Raloxifene and Vitamin K2 together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Raloxifene and Vitamin K2. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

2 studies naming Raloxifene and Vitamin K2.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Prospective evaluation of Vitamin K2, Raloxifene and their co-administration in osteoporotic rats.

European journal of pharmaceutical sciences : official journal of the European Federation for Pharmaceutical Sciences · 2011 · PMID 21575717

Animal study

“In summary, the groups R, K and R+K had significantly higher ultimate strength and less susceptibility to fracture than ovariectomized controls. In summation, Vitamin K2 treated groups (either in single or combined with Raloxifene) had considerable biomechanical performance and reproductive tissue profile indicating that this agent is prospectively effective in osteoporosis management.”

Tasci et al. · From the abstract

Names both Raloxifene and Vitamin K2 in its title.

Raloxifene and vitamin K2 combine to improve the femoral neck strength of ovariectomized rats.

Calcified tissue international · 2005 · PMID 16059775

Animal study

“Therefore, raloxifene and vitamin K2 had complementary effects on bone resorption and formation activities, respectively, resulting in a reproducible, significant improvement of femoral neck strength. These rat data suggest interesting therapeutic possibilities that may require clinical verification.”

Iwamoto et al. · From the abstract

Names both Raloxifene and Vitamin K2 in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Raloxifene, Vitamin K2, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
