Best Supplements for Heart health
13 evidence-based options for heart health, summarized from the research: what they do, how to dose them, and how they work together.
Berberine
A plant alkaloid with drug-like effects on blood sugar.
Coenzyme Q10 (CoQ10)
A mitochondrial antioxidant for cellular energy and heart health.
Folate (B9)
The active B vitamin behind methylation, mood, and pregnancy health.
L-Arginine
The nitric oxide precursor for blood flow and cardiovascular health.
L-Citrulline
A superior nitric oxide booster that outperforms arginine for pumps and endurance.
Omega-3 (Fish Oil)
Anti-inflammatory fats for heart, brain, and joints.
Psyllium Husk
A soluble fiber for regularity, cholesterol, and blood sugar.
Taurine
A conditionally essential amino acid for the heart, muscles, and calm focus.
TMG (Trimethylglycine)
A methyl-donor cousin of glycine for homocysteine, liver, and power.
Vitamin B1 (Thiamine)
The energy metabolism cofactor that keeps nerves and muscles firing.
Vitamin B12 (Cobalamin)
The methylation and nerve-health vitamin that protects the brain and blood.
Vitamin B3 (Niacin)
The NAD+ precursor that supports energy, cholesterol, and cellular repair.
Vitamin B6 (Pyridoxine)
The neurotransmitter cofactor behind mood, sleep, and homocysteine metabolism.

Combinations to know
How these supplements pair with each other and beyond.
Folate (B9) + TMG (Trimethylglycine)
TMG provides a folate-independent route to remethylate homocysteine (via BHMT), complementing the folate/B12 pathway, useful when folate cycling is impaired.
Folate (B9) + Vitamin B12 (Cobalamin)
Folate and B12 work as a pair in the methylation cycle. B12 is required for folate to re-enter active circulation; deficiency in either disrupts both.
Folate (B9) + Vitamin B6 (Pyridoxine)
B6 and folate work together to lower homocysteine and support methylation balance.
L-Arginine + L-Citrulline
L-Citrulline converts to arginine in the kidneys far more efficiently than oral arginine; the two share the same nitric oxide pathway.
Vitamin B12 (Cobalamin) + Vitamin B6 (Pyridoxine)
B6, B12, and folate form the homocysteine-methylation trio; imbalance in any one disrupts the others.
Coenzyme Q10 (CoQ10) + Omega-3 (Fish Oil)
Both support cardiovascular health and are frequently combined in heart-focused regimens; CoQ10 also helps protect omega-3 fats from oxidation.
Frequently asked questions
What are the best supplements for heart health?
The most-researched options are Berberine, Coenzyme Q10 (CoQ10), Folate (B9), L-Arginine, L-Citrulline, Omega-3 (Fish Oil), Psyllium Husk, Taurine, TMG (Trimethylglycine), Vitamin B1 (Thiamine), Vitamin B12 (Cobalamin), Vitamin B3 (Niacin), and Vitamin B6 (Pyridoxine). Each is summarised with its benefits, typical dosing, and the strength of the evidence behind it.
How were these heart health supplements chosen?
These are the supplements in the Vital Matrix library most commonly used for heart health, graded by the strength of human evidence. See our methodology for how we grade the research.
Can you combine supplements for heart health?
Yes, several pair well. For example, Folate (B9) and TMG (Trimethylglycine): TMG provides a folate-independent route to remethylate homocysteine (via BHMT), complementing the folate/B12 pathway, useful when folate cycling is impaired.
