Why do women need more choline than they're getting?
A controlled feeding study found that estrogen status changes how much choline the body needs, with postmenopausal women requiring more dietary choline than premenopausal women.† Most women fall short of recommended choline intake to begin with, and that gap widens as estrogen shifts across life stages, from preconception through pregnancy and beyond.
Always consult your healthcare provider before starting any new supplement, especially during pregnancy, breastfeeding, or while managing a medical condition.
What choline actually does in the body
Choline is the body's major dietary source of methyl groups, used to methylate homocysteine to methionine via its metabolite betaine.1 It's essential for cell membrane structure, cholinergic signaling, and lipid transport from the liver.2 Most people in the United States don't consume the recommended amount of choline through diet alone.3
Why women's choline needs are tied to estrogen — the real mechanism
A controlled feeding study found that postmenopausal women, who have lower estrogen, required more dietary choline than premenopausal women, and a specific genetic variant increased the requirement further in both groups.1 This shows a real, direct relationship between estrogen and choline requirements, driven by estrogen's activation of a liver enzyme (PEMT) involved in the body's own choline synthesis.1
Where the "estrogen detox" framing overreaches the evidence
This research shows that estrogen affects how much choline the body needs and can make on its own. It does not establish that supplemental choline clears out excess estrogen, which is a claim not supported by this literature. If you've seen choline marketed as an "estrogen detox" tool, that framing goes beyond what the underlying research actually shows.

Methylated folate and choline in a prenatal formula
Choline requirements increase further during pregnancy, and choline is important for fetal growth and central nervous system development.4 our prenatal with methylated folate, choline, non-constipating iron, and algae DHA, Total Prenatal supports healthy fetal brain and spinal cord development and includes choline alongside 21 other vitamins and minerals.†
"Every nutrient your body needs in a new season of life is a reminder that you were never meant to do this on default settings. Choline was one I had never even heard of until I needed it."

What this means for how you eat and supplement day to day
- Choline is found in eggs, meat, fish, and some plant sources like cruciferous vegetables.
- Requirements shift with life stage, and increase further during pregnancy.4
- A choline-rich prenatal formula can help close a nutritional gap most women already have, rather than functioning as a "detox" tool.
- Talk to your provider about your specific choline intake if you're pregnant, breastfeeding, or planning to conceive.
Frequently asked questions
Does estrogen really affect how much choline I need?
Yes. A controlled feeding study found postmenopausal women, with lower estrogen, needed more dietary choline than premenopausal women.1
Does choline "detox" excess estrogen from the body?
No, that claim isn't supported by the research. The studies show estrogen affects choline requirements, not that choline clears estrogen from the body.
Do most women get enough choline from food?
No. Most people in the United States fall short of recommended choline intake through diet alone.3
Why does choline matter more during pregnancy?
Choline requirements increase during pregnancy because of its role in fetal growth and central nervous system development.4
What foods naturally contain choline?
Eggs, meat, fish, and some plant sources like cruciferous vegetables are common dietary sources of choline.3
Is Total Prenatal safe while breastfeeding?
Total Prenatal is designed for preconception through breastfeeding, though you should always consult your healthcare provider before starting any new supplement during pregnancy or breastfeeding.†
