Understand choline and choline targets in the Nutrient Explorer

What it is

Choline is an essential nutrient that doesn’t fit neatly into one of the broad categories of essential nutrients (vitamins, minerals, essential fatty acids, and essential amino acids). 

What it does

Choline is a chemical precursor for two of the common phospholipids in cell membranes, and it’s a primary component of acetylcholine, which is one of the most abundant neurotransmitters. Finally, choline is an important methyl donor.

Recommended intake

The recommended intake of choline is 550mg per day for men and 425mg per day for women. Dietary choline intake should not exceed 3500mg per day.

Likelihood of tracking completeness: Very low

Choline is not a nutrient that food manufacturers are required to disclose on nutrition labels. The vast majority of food and beverage manufacturers do not voluntarily list choline content on nutrition labels, so most branded products in the MacroFactor database lack information on choline. So, if you’d like to accurately track your choline intake, you’ll need to make a point of mostly tracking “common foods,” which come from research-grade databases that have full nutrient reporting.

Likelihood of insufficient intake: High

In the US, the average choline intake is about 275mg/day for women, and 400mg/day for men.

Signs of deficiency/insufficiency

There aren’t obvious signs of insufficient choline intake. True choline deficiencies are rare because your body can generally synthesize enough choline to avoid gross deficiency. But, a choline deficiency can cause non-alcoholic fatty liver disease, muscle damage, and neurological symptoms (since a choline deficiency decreases acetylcholine production).

Good sources

Egg yolks, fish, liver, and shellfish are particularly good sources of choline. Legumes in general, and soybeans in particular, are good vegan sources of choline.
