Choline is well known for its roles in brain and liver function — but growing research also highlights its influence on cardiovascular health. 

A major review published in Nutrients (2018) summarises evidence connecting dietary choline with homocysteine metabolism, methylation pathways, and overall cardiovascular function.

How Choline Supports a Healthy Heart

1. Choline helps regulate homocysteine

High homocysteine is a known cardiovascular risk factor. Choline-derived betaine acts as a methyl donor, helping convert homocysteine back into methionine. Several population studies show an inverse relationship between choline/betaine intake and homocysteine levels.

2. Choline assists in lipid transport

By supporting phosphatidylcholine production in the liver, choline helps move fats out of the liver and into circulation, improving overall lipid metabolism.

3. Choline affects gene expression linked to vascular health

Choline plays a central role in methylation reactions that influence DNA methylation — a key regulatory factor for inflammation, vessel health, and metabolic function.

4. Some studies show higher choline intake correlates with better cardiovascular outcomes

While research is mixed, several cohort studies report that individuals with higher plasma choline or betaine tend to have lower cardiovascular risk markers.

An Easy Food-Based Source of Choline

Sunflower lecithin provides phosphatidylcholine — a highly bioavailable choline source used by the body to support methylation, lipid transport, and cell membrane health.

Bottom Line

Choline doesn’t get as much attention as omega-3s or fibre, but its impact on cardiovascular health is undeniable — and many adults fall short of their daily requirements.

Supporting your diet with a natural phosphatidylcholine source is an easy step toward better heart health.
