Choline is an essential nutrient found in foods such as eggs, liver, meat, fish, dairy, soy and some vegetables. It is often mentioned in relation to pregnancy, but choline is also worth reviewing during the preconception window, before conception has happened.
Choline is relevant before conception because it is involved in methylation, cell membrane structure and early cellular development, processes that are directly relevant to egg and sperm cell biology. Diet is a useful place to start when thinking about choline, since food naturally provides choline in varying amounts depending on what you eat day to day.
Food should be the first place to start when reviewing choline intake. A supplement may be worth reviewing if dietary intake is low, or if a prenatal or preconception supplement contains little choline. If you are trying to conceive, reviewing choline-rich foods can be a useful first step before deciding whether you need additional choline support.
Short answer: The best choline foods include eggs, liver, beef, chicken, fish, dairy products, soybeans, edamame, beans, broccoli, Brussels sprouts and whole grains. Eggs are one of the most practical everyday sources because the yolk contains concentrated choline. Choline is involved in methylation, cell membrane structure and early cellular development, so it may be worth reviewing as part of a personalised preconception nutrition plan.
The most useful choline-rich foods to review before pregnancy are eggs, liver, meat, fish, dairy products, soy foods, legumes, cruciferous vegetables and whole grains.
Animal foods usually provide more concentrated choline than plant foods, but plant foods can still contribute to overall intake.
Choline is involved in choline for fertility through several biological pathways that are relevant to preconception health, including methylation, cell membrane structure, phosphatidylcholine synthesis, cell signalling and lipid metabolism.1
These pathways relate closely to early cellular development and to egg and sperm cell biology, since both reproductive cells and early-stage cells rely on healthy membranes and correct methylation patterns to function normally.2
Choline is not a fertility treatment, but it is involved in biological pathways that are relevant before conception.
The European Food Safety Authority has set an adequate intake for choline of 400mg per day for adults, with higher reference values during pregnancy and lactation.4 These are population reference values, not personalised supplement instructions.
Many people may not know how much choline they are getting from food, and some preconception or prenatal supplements contain little or no choline. Reviewing your usual diet alongside your supplement routine can help identify potential gaps before deciding whether further support may be worth reviewing.
Egg yolks are one of the most practical everyday sources of choline. If someone eats eggs regularly, they may already be getting a useful contribution from food. Eggs are not required for adequate choline intake, but they are a convenient option for many people.
Liver is one of the richest dietary sources of choline, but it is not suitable or appealing for everyone. Because vitamin A intake can be a concern around pregnancy planning, liver is worth approaching carefully rather than eating frequently. If you eat liver regularly, or use supplements that already contain high levels of vitamin A, it is worth reviewing this with a healthcare practitioner.
Beef, chicken and turkey can contribute to choline intake as part of a varied diet that includes other protein sources.
Fish such as salmon, cod and tuna can contribute choline and may also provide other nutrients relevant to preconception nutrition. As with any dietary choice before pregnancy, it is worth reviewing fish intake as part of a wider, personalised nutrition plan.
Milk, yoghurt and cottage cheese can contribute smaller amounts of choline and can be a useful part of a varied diet.
Soybeans, edamame, tofu, chickpeas and beans can contribute choline, especially for people who eat fewer animal products.
Broccoli, Brussels sprouts, mushrooms, potatoes, wheat germ and whole grains provide smaller amounts but can still contribute as part of a varied diet.
The table below summarises practical choline food sources. Exact milligram values have not been included here, as this is a qualitative guide rather than a nutrient database; for verified figures, see USDA FoodData Central.5
| Food | Why it is useful | Practical note |
|---|---|---|
| Eggs | One of the most practical everyday choline sources | The yolk contains most of the choline |
| Liver | One of the most concentrated sources | Review intake carefully because liver is also high in vitamin A |
| Beef or chicken | Useful everyday protein source that also contributes choline | Part of a varied diet rather than a standalone source |
| Salmon, cod or tuna | Contributes choline alongside other preconception-relevant nutrients | Review overall fish intake as part of a personalised plan |
| Milk, yoghurt or cottage cheese | Everyday dairy foods that provide smaller, steady amounts | Useful as part of a varied diet rather than a primary source |
| Soybeans or edamame | Useful plant-based source | Helpful for vegetarian diets |
| Chickpeas or beans | Contributes to overall plant-based choline intake | Useful alongside other legumes and whole grains |
| Broccoli or Brussels sprouts | Cruciferous vegetables that provide smaller amounts | Best considered alongside other food sources, not alone |
| Mushrooms or potatoes | Everyday vegetables that can contribute small amounts | Useful as part of a varied plate rather than a main source |
| Wheat germ or whole grains | Provides smaller amounts alongside fibre and other nutrients | Useful addition to a varied preconception diet |
Some people may be able to get meaningful choline from food, especially if they regularly eat eggs, fish, meat, dairy or soy foods. Others may find it harder, especially if they avoid eggs, eat little animal protein, follow a vegetarian or vegan diet, or use a preconception supplement that contains little choline.
The aim is not to assume everyone needs a choline supplement, but to understand whether your usual diet and current supplement routine are likely to cover your needs. It may be worth taking time to review your choline intake before pregnancy, particularly if your diet is limited in the food groups above.
Vegetarian and vegan diets can include choline, but the most concentrated sources are often animal-based. Plant-based choline sources include:
People following vegetarian or vegan diets may want to review choline intake more deliberately, especially when preparing for conception. This does not mean vegetarian or vegan diets are inadequate overall, simply that choline intake may benefit from more deliberate planning around plant-based sources.
Choline and folate are different nutrients, but both are involved in methylation-related pathways. Choline does not replace folate, and folate remains a core preconception nutrient. For more detail on folate specifically, see folate vs folic acid.
Many people focus on folate first, but choline may need separate review because many prenatal supplements contain little choline. For people also reviewing PCOS (PMOS), insulin signalling or supplement combinations, our guide to choline and inositol for fertility explains how these nutrients differ.
A choline supplement may be worth reviewing if your diet is low in choline-rich foods, your prenatal or preconception supplement contains little choline, or you want targeted support as part of a personalised fertility nutrition plan.
This may be worth considering if:
Zita West Choline provides 400mg choline per daily serving and is designed to support choline intake as part of a wider preconception nutrition plan. Choline is involved in methylation, cell membrane structure and early cellular development.
Shop nowCholine intake can be reviewed during the three-month preconception window alongside other nutrients, diet, lifestyle and supplement routines. Sperm development takes roughly 70 to 90 days, and egg maturation and the follicular environment are influenced in the weeks before ovulation.
This does not mean changes guarantee outcomes. It simply provides a useful planning window for reviewing diet and nutrient intake, including other fertility nutrients to review before pregnancy.
Eggs, liver, meat, fish, dairy, soybeans and legumes are among the foods that contribute most to choline intake. Egg yolks and liver are especially concentrated sources, but not everyone eats liver, and it is worth reviewing liver intake carefully because of its vitamin A content.
Yes. Eggs, especially the yolk, are one of the most practical everyday sources of choline. Choline is involved in methylation and cell membrane structure, both relevant before conception.
Some people may be able to get meaningful choline from food, especially if they regularly eat eggs, fish, meat, dairy or soy. Others may find it harder if they avoid eggs or animal foods, or if their prenatal contains little choline.
Choline may be worth reviewing before pregnancy because it is involved in methylation, cell membrane structure and early cellular development. For a broader overview, see choline for fertility.
No. Choline and folate are different nutrients, although both are involved in methylation-related pathways. Choline does not replace folate, and folate remains a core preconception nutrient. See our guide to folate vs folic acid for more detail.
Not necessarily. Vegetarian and vegan diets can include choline, but some of the most concentrated sources are animal-based, such as eggs, liver, meat, fish and dairy. People who avoid these foods may want to review plant-based choline sources more deliberately, including soybeans, edamame, tofu, chickpeas, beans, broccoli, Brussels sprouts, potatoes, mushrooms, wheat germ and whole grains.
Not everyone needs to supplement. A choline supplement may be worth reviewing if someone eats few choline-rich foods, avoids eggs or animal products, uses a prenatal with little choline, or wants targeted support as part of a personalised preconception nutrition plan. Personalised guidance from a healthcare practitioner or fertility nutrition specialist is recommended.
The European Food Safety Authority has set an adequate intake for choline of 400mg per day for adults, with higher reference values during pregnancy and lactation. This is a population reference value, not personalised supplement advice.
Liver is one of the richest choline food sources, but it is also high in vitamin A. If you regularly eat liver, use high-vitamin-A supplements, or are actively trying to conceive, it is worth getting personalised advice on how liver fits into your diet.
Eggs are likely the most practical everyday source for many people who do not eat liver, especially because the yolk contains concentrated choline. Fish, meat, dairy, soybeans, edamame, legumes and whole grains can also contribute.
Choline is involved in methylation, cell membrane structure and early cellular development, which are relevant before conception. However, it should not be presented as a fertility treatment or a guarantee of improved outcomes.
Choline is relevant to male fertility nutrition because it is involved in cell membrane structure and methylation, and some research has explored genes involved in choline metabolism in relation to sperm concentration.3 This should not be read as evidence that choline-rich foods improve sperm count or motility. Men trying to conceive may want to review choline intake as part of a wider nutrition and lifestyle plan.
Sperm development takes roughly 70 to 90 days, while egg maturation and the follicular environment are influenced in the weeks before ovulation. Reviewing choline intake around three months before trying to conceive is a useful planning window for reviewing diet and supplement routines, not a guarantee of improved fertility outcomes.

No, a man cannot be "too old" to conceive in the way a woman can, but age does matter. Sperm is produced fresh on a roughly 70–90 day cycle, which means quality is not fixed. Even after a disappointing semen analysis, many men in their 40s and beyond can make meaningful improvements to count, motility, morphology and DNA integrity. Age raises certain risks, but it rarely closes the door.
