Most people don’t realise that choline is essential for liver function — and that inadequate intake can lead to fat accumulation in the liver within weeks.
A comprehensive review published in Nutrients (2018) highlights how choline deficiency contributes to fatty liver, impaired lipid transport, and muscle damage.

Despite its importance, surveys show that many adults fall short of recommended choline intake.
Why Choline Is Critical for a Healthy Liver
1. It prevents fat buildup in the liver
Choline is required to produce phosphatidylcholine, which helps package fats so they can be transported out of the liver. Without enough choline, fat can accumulate rapidly.
2. It protects cell membranes
Low choline reduces phosphatidylcholine levels, weakening liver cell membranes and increasing susceptibility to damage.
3. It supports methylation and detoxification
Choline-derived betaine plays a key role in homocysteine methylation and overall liver metabolism.
4. Deficiency causes measurable liver changes within weeks
In one human study, healthy men developed signs of liver dysfunction after only three weeks on a choline-deficient diet.
A Simple Way to Increase Daily Choline Intake
Sunflower lecithin is one of the easiest and cleanest ways to boost phosphatidylcholine intake — with the added benefit of being plant-based and soy-free.

The Takeaway
Given how common low choline intake is — and how quickly deficiency can affect the liver — supporting your diet with a natural source of phosphatidylcholine is a smart, proactive approach.
