How to read this section

  • Match % - how closely the study matches this product (not overall scientific quality).
  • Evidence type - study design (RCT, review, etc.) and whether it is direct, category-level, or indirect.
  • What it found - short summary and quoted extract from the paper metadata. Not medical advice.
Direct product evidenceThis study closely matches this product or its active ingredient.

In plain language

A 100‑person, vitamin‑D‑deficient early knee‑OA cohort was split into vitamin D3 alone vs. vitamin D3 + virgin coconut oil for several weeks. Serum 25(OH)D rose, inflammatory markers (ESR, CRP) and cartilage degradation marker s‑COMP fell, pain (VAS) and WOMAC scores improved, and 6‑minute walk distance increased, with greater gains in the combined group. [1]

What the study reported

Verified extract — not AI generated

“Improved vitamin D status, reduced inflammation and cartilage degradation, lower pain, better functional mobility.”

How it was used

Vitamin D3 supplement (dose not specified) plus virgin coconut oil; participants also followed a home‑based knee‑OA exercise program.

Side effects noted

None reported in the abstract.

Caveats

Dose of vitamin D3 not disclosed, short‑term study, limited to early knee OA patients, not a general‑population trial.
