The Adequate Intake for choline is 550 mg/day for adult men and 425 for adult women; a bit more if you’re pregnant (450) or breastfeeding (550). Here’s more from the Nutrition Diva podcast on choline’s important role–in particular, during pregnancy.
I’m always in favor of getting our nutrients from foods rather than supplements—especially when this motivates us to prioritize whole foods in our diets. Below is a table showing some good dietary sources of choline.
| Food | Typical Serving | Choline (mg) |
|---|---|---|
| Beef liver, cooked | 3 ounces (85 grams) | 350 |
| Chicken liver, cooked | 3 ounces (85 grams) | 250 |
| Egg yolk | 1 large | 150 |
| Lean beef, cooked | 3 ounces (85 grams) | 120 |
| Chicken breast, cooked | 3 ounces (85 grams) | 75 |
| Soymilk | 1 cup | 60 |
| Shiitake mushrooms | ½ cup | 60 |
| Edamame, shelled | ½ cup | 50 |
| Kidney beans, cooked | ½ cup | 45 |
| Tofu | ½ cup | 35 |
| Brussels sprouts, broccoli | ½ cup | 30 |
| Sunflower seeds | ¼ cup | 20 |
| Brown rice | ½ cup | 10 |
Checked several of these against the NIH ODS choline table before trusting the table, and they hold: beef liver 3 oz = 356 mg (yours 350), one large egg = 147 (150), lean beef 3 oz = 117 (120), chicken breast 3 oz = 72 (75), Brussels sprouts 1/2 cup = 32 (30), brown rice 1/2 cup = about 10 (10). The AI figures also match the IOM 1998 values (550 men / 425 women / 450 pregnant / 550 lactating).
One stray word: the sentence above the table says “good dietary sources of potassium.” The table is choline.
