Taking omega-3 fish oil alongside vitamin D3 daily. Two of the most common supplement staples, often used to support heart, brain, and overall health, especially where sun exposure is limited.

Quick facts

  • 1Omega-3s (EPA and DHA) and vitamin D are the two most widely taken longevity-adjacent supplements.
  • 2Large trials like VITAL showed mostly neutral primary results with interesting subgroup signals for both.
  • 3Vitamin D status depends heavily on latitude, season and sun exposure; testing beats guessing.
  • 4Fat-soluble compounds absorb better with meals.

Why people do it

  • Covers common gaps: Low fish intake and indoor northern living make these the two most defensible defaults.

  • Cardio and inflammation interest: Omega-3 research on triglycerides is solid; broader cardiovascular findings are mixed but active.

  • Bone and immune roles: Vitamin D's core physiology is uncontroversial even where supplement trials disappoint.

Good to know

  • Not medical advice: Supplement responses and interactions are individual; people typically review their stack with a clinician, especially alongside medication.

  • Quality varies: Third-party tested brands matter in a loosely regulated market.

Common questions

Should I test vitamin D first?+

The longevity crowd generally tests before and after rather than dosing blind; levels vary enormously.

Fish oil quality matters?+

Yes: oxidation is the known issue, so fresh, tested brands and refrigeration are the practice.

Takeaway

The default stack of the longevity world: sensible gap-covering with honest, mixed trial evidence. Test, take with food, review annually.

    I keep mine simple: fish oil + D3 with breakfast. Consistency beats complexity.
