Most clinical trials on dates and labor use deglet noor or medjool dates, the two varieties most widely available in grocery stores. The specific type matters less than the amount: roughly 70 to 75 grams per day (about six dates), starting around 36 to 37 weeks of pregnancy. That’s the dose and timing consistently linked to shorter labor and a higher chance of going into labor on your own.
Which Varieties Work Best
The largest studies used common commercial varieties, primarily deglet noor and medjool. Deglet noor dates are the smaller, drier, amber-colored ones often sold in boxes or bags at standard grocery stores. Medjool dates are larger, softer, and chewier, usually sold individually or in small containers in the produce section. Both deliver the same key components: natural sugars for energy, fatty acids that support labor-related hormones, and calcium that helps uterine muscles contract.
There’s no clinical evidence that rarer or more expensive varieties like ajwa, khudri, or barhi offer additional benefits for labor. If you can find them and enjoy the taste, they’re fine. But you don’t need to order specialty dates online. Whatever is on the shelf at your local store will match what researchers actually tested.
How Many to Eat and When to Start
The most-studied protocol is 70 to 75 grams of dates per day, which works out to about six deglet noor dates or three large medjool dates. Start at 36 or 37 weeks and continue daily until labor begins. In clinical trials, two weeks of consistent consumption was considered the minimum for any meaningful effect, so starting earlier in that window gives you more time to benefit.
You don’t need to eat them all at once. Many women spread them throughout the day: a couple with breakfast, a few as an afternoon snack, or blended into a smoothie. Chopped dates stirred into oatmeal or yogurt are another easy option if eating them plain gets repetitive.
What Dates Actually Do During Late Pregnancy
Dates appear to work through several pathways that prepare your body for labor. The fatty acids in dates stimulate production of prostaglandins, hormone-like compounds your body needs to soften and thin the cervix before contractions begin. Dates are also rich in calcium, which helps the smooth muscle of the uterus contract more effectively. And there’s evidence that compounds in dates help your uterine muscle respond better to oxytocin, the hormone that drives contractions.
The result is a cervix that’s more “ready” when labor starts. In one study of 210 women, those who ate 75 grams of dates daily arrived at the hospital with significantly better cervical readiness scores: 7.6 on average compared to 5.1 in the group that didn’t eat dates. That difference can mean the difference between being sent home to wait and being admitted in active labor.
What the Research Shows About Labor Outcomes
The headline finding across multiple trials is a higher rate of spontaneous labor. In one study, 84% of women who ate dates went into labor on their own, compared to 61% of women who didn’t. That’s a meaningful gap, especially for first-time mothers hoping to avoid medical induction.
The need for synthetic oxytocin (used to start or speed up contractions) also dropped. Only about 33% of the date group needed it, versus 51% of the control group. A meta-analysis pooling data from several trials found that date consumption shortened the early phase of labor by an average of 4.6 hours and the pushing stage by about 8 minutes. The early labor reduction is the more noticeable benefit for most women, since that’s the long, exhausting stretch of contractions before active labor kicks in.
These findings are consistent but come from relatively small studies, mostly involving first-time mothers. The effects for women who’ve given birth before are less well studied, though the biological mechanisms would apply regardless.
Dried vs. Fresh Dates
Most dates sold in the U.S. and Europe are technically dried or semi-dried, and that’s exactly what researchers used. Fresh dates (the yellow or red ones picked before full ripening) are harder to find and haven’t been specifically studied for labor outcomes. Stick with the soft, brown dates you’d find at any grocery store. Whether the package says “dried” or not, these are the ones used in the research.
Avoid dates coated in added sugar or syrup. Date syrup and date paste also haven’t been studied as substitutes, and the processing may alter the fatty acid content that’s thought to drive the prostaglandin effect. Whole fruit is your best bet.
Sugar Content and Gestational Diabetes
Six dates contain roughly 50 to 60 grams of sugar, which is a significant amount. For most pregnant women, this is well tolerated, especially when eaten alongside protein or fat to slow absorption. But if you have gestational diabetes or are monitoring blood sugar closely, the picture is more complicated.
Research on dates and diabetes has not specifically included pregnant women, so there’s no clear safety data for this group. The glycemic index of dates varies by variety (medjool tends to be moderate, in the mid-40s to low-50s range), but the sheer sugar load in six dates per day could affect blood sugar management. If you’ve been diagnosed with gestational diabetes, talk to whoever is managing your blood sugar before adding dates to your daily routine. You may be able to eat a smaller amount, or you may need to skip them entirely depending on how well your levels are controlled.
Practical Tips for Daily Consumption
- Weigh rather than count. Dates vary in size. A kitchen scale set to 70 grams is more reliable than counting six dates, especially if you’re using large medjools.
- Pit them first. Whole dates with pits are cheaper, and removing the pit gives you space to stuff them with nut butter or cream cheese for a more filling snack.
- Blend them into smoothies. Two or three dates blended with milk, banana, and a spoonful of peanut butter makes the daily dose easy to get in one sitting.
- Store at room temperature. Dried dates keep for weeks in a sealed container. Refrigeration firms them up, which some people prefer, but it’s not necessary.
Consistency matters more than timing within the day. The benefits in the research came from eating dates every day for at least two to three weeks before delivery, not from eating a large amount on any single day.
