Most people have never heard of choline.
That is part of the problem. It is one of the most important nutrients in the human body and one of the most consistently underconsumed. It does not have a catchy reputation. It does not trend on wellness social media. It just quietly does some of the most essential work in your body every single day.
Here is what it actually does and why most people are not getting enough of it.
What Choline Actually Does
Choline is an essential nutrient. The body produces small amounts on its own but not nearly enough to meet its needs. The rest has to come from food.
It serves several critical functions simultaneously.
Every cell membrane in your body contains phosphatidylcholine, a fat that choline is a primary building block of. Without adequate choline, cell membrane integrity suffers. That is not an abstract concern. It affects every tissue in the body.
Choline is the precursor to acetylcholine, one of the most important neurotransmitters in the nervous system. Acetylcholine is directly involved in memory formation, learning, and muscle contraction. When choline is low, acetylcholine production drops. The effects show up as brain fog, poor recall, and difficulty concentrating.
Choline is also essential for fat metabolism in the liver. It enables the liver to process and export fat rather than accumulate it. Research has found that a diet deficient in choline causes fatty liver and muscle dysfunction within weeks. In one study, 77 percent of men and 80 percent of postmenopausal women developed liver or muscle damage after just weeks on a choline-deficient diet.
Who Is Most at Risk
Despite how essential choline is, most people are not meeting the recommended intake. Studies consistently show that the majority of adults fall short, with the gap most pronounced in pregnant women, older adults, and people eating primarily plant-based diets.
Pregnant women have the highest choline needs of any group. Choline is used rapidly by the developing fetal brain during gestation. The American Academy of Pediatrics recognizes choline as a brain-building nutrient and specifically calls for adequate intake during pregnancy. Most prenatal vitamins do not contain meaningful amounts of it. Most pregnant women do not know they are deficient.
Older adults face a compounding problem. Choline requirements do not decrease with age but dietary quality often does. Research suggests adequate choline intake is associated with better cognitive function in older people, which makes the widespread deficiency in that demographic particularly significant.
People with certain genetic variants, estimated at around 50 percent of the population, have higher choline requirements than the standard recommendations account for. For these individuals, standard dietary intake is not sufficient regardless of how carefully they eat.
Why Most Diets Fall Short
Choline is found almost exclusively in animal foods. Eggs are the most well-known source. Liver is the most concentrated source available by a significant margin.
A single three-ounce serving of beef liver delivers around 330mg of choline. The adequate intake for most adults is 425 to 550mg per day. One serving of liver covers the majority of that requirement in a form the body absorbs efficiently.
The shift away from organ meats over the past sixty years removed the most reliable dietary source of choline from most people's plates. Eggs partially fill the gap but most people are not eating enough of them to compensate fully. The result is a population that is quietly deficient in a nutrient that supports brain function, liver health, cell integrity, and fetal development.
Plant foods contain very little choline and in forms that are less bioavailable than animal sources. For people eating primarily plant-based diets, deficiency is not a risk. It is a near certainty without deliberate supplementation.
The Simplest Fix
Getting adequate choline does not require a complicated supplement stack.
Beef liver is the most direct solution. It delivers choline in its natural whole food form alongside the cofactors that support its absorption and utilization. Nothing is isolated, nothing is synthetic. It is simply the food that contains the most of what you need.
Our Beef Liver is one ingredient. Grass-fed, freeze-dried, nothing added. Three capsules delivers a meaningful dose of choline alongside B12, retinol, heme iron, copper, and folate. It is the most nutrient-dense single food available and choline is one of the clearest reasons why.
If you are experiencing brain fog, difficulty concentrating, or you are pregnant or planning to be, choline is one of the first things worth looking at. Not because it is a trend. Because it is essential and most people are not getting enough of it.
