Four softgels daily of single-sourced anchovy oil (2:1 EPA/DHA ratio), 4,000 IU D3, and 120mcg K2 MK-7—the trio most midlife women are deficient in. Re-esterified to triglyceride form for better absorption, grass-fed gelatin capsules, third-party tested for purity. Reviewers report no stomach upset or fishy burps; main complaint is the large pill size and four-per-day dosing frequency.
Omega-3 supplementation has robust RCT support for cardiovascular outcomes and triglyceride reduction, particularly at higher doses (≥2g EPA/DHA daily). Vitamin D3 shows RCT evidence for bone health and immune function, especially in deficient populations. Vitamin K2 has mechanistic and observational support for bone and cardiovascular health, though fewer large RCTs. The combination is rational but no single RCT directly tests all three together; the verdict reflects the strength of evidence for each component individually.
Omega-3 fatty acids (EPA/DHA, eicosapentaenoic/docosahexaenoic acid) reduce systemic inflammation and support cardiovascular and neurological function. Vitamin D3 regulates calcium homeostasis and immune function. Vitamin K2 activates osteocalcin and matrix Gla protein, directing calcium to bone and away from soft tissues. Together, the combination is proposed to support bone health, cardiovascular function, and inflammation control.

“BACKGROUND: Randomized controlled trials (RCTs) assessing use of long-chain omega-3 polyunsaturated fatty acids (LC-OM3), primarily eicosapentaenoic acid, and/or docosahexaenoic acid have shown mixed results.”

Omega-3 RCTs show modest cardiovascular benefit in primary prevention and mixed results in secondary prevention (REDUCE-IT and STRENGTH trials had divergent outcomes). Vitamin D3 benefit is clearest in deficient individuals; supplementation in replete populations shows smaller effects. Vitamin K2 human RCT data is limited compared to K1; most evidence is observational or mechanistic. The synergistic claim (that all three together amplify benefit) lacks direct human trial support. Dosing and bioavailability of K2 forms vary widely.
