Best Vitamin K products by transparent scoring (2026)
Single-ingredient products scored by public rules: dose fit, label transparency, data verification, company transparency, third-party testing. Not a measure of efficacy or safety. No paid placement.
Products ranked: 47 · Reference range: ≥ 120 mcg (source) · Updated 2026-11-01
Reference range: from 100% of the US Daily Value upward. No authority we cite sets an upper limit for this ingredient, so higher doses are not marked down. That does not mean higher doses are proven safe.
Single-ingredient products only.
Left out of this list: daily dose above 12,000 mcg (100× DV), treated as a likely label error (1); combination products (a single-ingredient list exists) (21)
