Registry ingredients

Structured entries from our supplement intelligence registry (not personalized recommendations).

  • Omega-3 EPA/DHA (fish oil / re-esterified triglyceride)fatty acid

    Evidence tier: high·Typical label range: Supplements often 250-2000 mg combined EPA+DHA/day; Rx omega-3 acids grams.

  • Vitamin D3 (cholecalciferol)vitamin

    Evidence tier: high·Typical label range: Maintenance often discussed around 600-800 IU/day (IOM context) vs higher prescriptions for deficiency - toxicity is possible at sustained very high doses.

  • Vitamin K2 (MK-7 menaquinone)vitamin

    Evidence tier: medium·Typical label range: No RDA separate from K1; MK-7 labels often 45-180 mcg.

What this stack claims

Marketed as a ‘foundational’ longevity trio covering lipids, vitamin D repletion, and vitamin K ‘balance’.

Biological logic

EPA/DHA affect triglycerides and membrane composition; vitamin D is steroid-hormone-like in physiology; K2 participates in vitamin-K-dependent protein carboxylation relevant to bone/vascular biology. Taking fat-soluble nutrients with a fatty acid source can aid absorption practically.

Evidence level

Registry tier for this stack: MEDIUM

EPA/DHA evidence is strongest for high triglycerides (often at prescription doses) and for general cardiovascular risk discussions with clinicians - not for everyone at low dose as a miracle shield. D3 value depends on status. K2 add-on is mechanistically interesting but not universally required.

Risks

Bleeding caution with anticoagulants/antiplatelets at higher omega-3 intakes; vitamin D excess; K/warfarin coordination; fish allergy; rancid oil quality issues.

Final verdict

A **coherent intake pattern** for some clinician-guided plans, but **oversold** as a default ‘everyone should’ stack without labs, diet context, or medication review.

FAQ

Should these be taken together at the same meal?
Often yes for absorption comfort (fat-soluble vitamins with dietary fat / oil capsule), but timing matters less than consistency and dose appropriateness.
Is algae oil interchangeable here?
For many people, algal EPA/DHA can substitute for fish oil; product EPA/DHA content and quality still matter.
Does this replace statins or BP meds?
No. It is not an exchange for prescribed cardiometabolic therapy.
