Best Supplements for Heart health
4 evidence-based options for heart health, summarized from the research: what they do, how to dose them, and how they work together.
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.
Combinations to know
How these supplements pair with each other and beyond.
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.
Folate (B9) + Iron
Both folate and iron are needed for healthy red blood cell production. Deficiency in either causes anaemia.
Folate (B9) + Magnesium
Magnesium is a required cofactor for many methylation enzymes; low magnesium can limit the benefit of folate supplementation.
Folate (B9) + L-Tryptophan
Folate supports the methylation cycle needed to recycle and activate neurotransmitter cofactors.
Folate (B9) + L-Tyrosine
Methylation via folate is required to activate cofactors in catecholamine synthesis.
L-Arginine + Magnesium
Magnesium supports vascular smooth muscle relaxation alongside nitric oxide from arginine.
