Best Supplements for Heart Health

Cardiovascular disease remains the leading cause of death globally. These supplements have the strongest expert consensus for supporting heart health, backed by clinical trial data.

This content is based on expert analysis of publicly available videos, not medical advice. Always consult your healthcare provider before starting, stopping, or changing any supplement.

Top Supplements for Heart Health

1

Omega-3

4.8 /5

All 5 experts actively recommend omega-3 supplementation, making this one of the strongest consensus topics. Patrick and Attia provide the deepest mechanistic coverage, Huberman recommends 1-3g EPA for mood and cognition, Hyman lists omega-3 as a foundational supplement everyone needs, and Johnson includes omega-3 sources in his Blueprint diet.

2

Magnesium

4.1 /5

4 of 5 experts actively recommend magnesium supplementation. Patrick and Hyman are the strongest advocates, each discussing it across multiple videos. Attia recommends 300-500mg daily for bone health and personally supplements with three forms. Johnson's Blueprint stack does not explicitly include magnesium.

Strong
3

Vitamin D

3.9 /5

4 of 5 experts recommend vitamin D supplementation for those with suboptimal levels, though Attia urges caution — arguing that the health benefits attributed to high vitamin D may actually come from the outdoor lifestyle needed to achieve them naturally. Patrick is the strongest advocate, citing a 40% reduction in dementia risk.

Strong
4

CoQ10

3.7 /5

CoQ10 receives strong endorsement from Hyman, who has a dedicated deep dive and recommends it across 20+ videos as a cornerstone of mitochondrial support. Huberman mentions CoQ10 as a beneficial fertility supplement. Johnson includes CoQ10 in his Blueprint oral health protocol. Attia and Patrick do not specifically discuss CoQ10 supplementation in their analyzed content, though both emphasize mitochondrial health through other interventions.

Strong
5

Vitamin K2

3.0 /5

3 of 5 experts recommend vitamin K2 — Hyman always pairs it with D3, Patrick provides the deepest mechanism via Triage Theory, and Johnson takes D3K2 daily. Attia conspicuously omits K2 from his bone health 'big three' (calcium, D3, magnesium) despite extensive bone health content. Huberman has zero coverage.

Moderate

The Cardiovascular Protection Stack

The highest-evidence supplements for heart health:

  • Omega-3 (high EPA) — 1.5-4g EPA daily; REDUCE-IT trial showed significant CV risk reduction (Attia)
  • Magnesium — 300-500mg daily; deficiency linked to arrhythmias and hypertension (Attia, Hyman)
  • Vitamin D3 + K2 — K2 directs calcium to bones, away from arteries (Hyman, Patrick)

Common Mistakes

Taking calcium supplements without vitamin K2. Hyman warns this may direct calcium to arteries rather than bones.

Using low-quality fish oil that is oxidized. Attia emphasizes triglyceride form and proper storage.

Relying on supplements while ignoring the fundamentals: exercise, blood pressure management, and metabolic health.

Not testing your omega-3 index. Attia and Patrick recommend targeting 8-12%.
