Heart & Cardiovascular

12 products graded for this goal, sorted by strength of evidence.

Magnesium

A

A foundational mineral most people under-consume — strong for correcting inadequacy, modest (not magical) for sleep.

Sleep & StressHeart & CardiovascularMuscle & Athletic Performance

Omega-3 Fish Oil

A

EPA and DHA from fish oil have strong cardiovascular and cognitive evidence — but dose, form, and freshness matter more than most labels suggest.

Heart & CardiovascularBrain & Cognitive

Aged Garlic Extract

B

Specifically the aged (Kyolic-style) form of garlic with several RCTs showing modest but real reductions in blood pressure and cholesterol.

Heart & CardiovascularImmune

Berberine

B

A plant alkaloid with strong clinical evidence for lowering blood sugar, often compared to metformin in efficacy for glycemic control.

Metabolic & WeightHeart & Cardiovascular

Betaine (TMG)

B

A methyl donor with solid evidence for lowering homocysteine and moderate evidence for improving power output and body composition during resistance training.

Heart & CardiovascularMuscle & Athletic Performance

Citrulline Malate

B

An amino acid that boosts nitric oxide production — good evidence for improving exercise performance and blood flow, though effect sizes are moderate and study quality varies.

Muscle & Athletic PerformanceHeart & Cardiovascular

CoQ10 (Ubiquinol)

B

A mitochondrial coenzyme critical for cellular energy production, with good evidence for heart health support and addressing statin-related depletion.

Heart & CardiovascularEnergy & Fatigue

Ginkgo Biloba

B

One of the most-studied herbal supplements in history, with mixed but meaningful evidence for circulation and cognition — though the large dementia-prevention trials were negative.

Brain & CognitiveHeart & Cardiovascular

Taurine

B

A conditionally essential amino acid with solid evidence for cardiovascular protection and emerging longevity interest, though human lifespan data is still absent.

Heart & CardiovascularEnergy & Fatigue

Vitamin E (Mixed Tocopherols)

B

A fat-soluble antioxidant that protects cell membranes — essential from food, but supplementation evidence is mixed and high doses may carry risk.

Heart & CardiovascularSkin & Anti-Aging

Vitamin K2 (MK-7)

B

Directs calcium toward bones and teeth and away from arteries — promising evidence for cardiovascular and skeletal health, especially alongside vitamin D.

Heart & CardiovascularJoint & Bone

Resveratrol

C

The famous 'red wine molecule' has disappointing human translational evidence despite decades of hype — a classic case of animal data not panning out.
