Is wheatgrass safe during pregnancy?

What does the evidence say about wheatgrass during pregnancy?

1. The FDA specifically advises pregnant women to avoid raw sprouts of any kind, including alfalfa, clover, radish, and mung bean, because bacteria can get inside the seed before it even sprouts, which makes contamination essentially impossible to wash off. 1
2. The same FDA guidance tells pregnant women to avoid fresh-squeezed juice sold by the glass at farmers markets, juice bars, or roadside stands unless it's been pasteurized or gone through another safety step, which is exactly how a fresh wheatgrass shot is typically prepared and served. 1
3. The mechanism behind sprout-related outbreaks is that contamination lives inside the seed itself: pathogen levels can exceed 10 million per gram of sprouts grown from a contaminated seed batch without any visible change, and applying chlorinated water or other disinfectants to the seeds or sprouts fails to eliminate the bacteria. 2
4. Wheatgrass itself is a genuine source of nutrients, including protein, fiber, chlorophyll, vitamins A, B, C, and E, and minerals like iron, calcium, and magnesium, which is part of why it's a popular add-in even though the fresh-juiced form carries the same food-safety concerns as other raw sprouted products. 3
5. In one of the few human trials using wheatgrass juice, adult patients drank about 60 mL (roughly 2 ounces) a day for several months with good adherence and no serious reported problems, though that study wasn't in pregnant women and doesn't stand in for pregnancy-specific safety data. 4

Is wheatgrass safe in each trimester?

• First trimester. There's nothing trimester-specific about wheatgrass in the first trimester. The same raw-juice, sprouted-seed caution applies from the very start of pregnancy through the end.
• Second trimester. The caution stays the same in the second trimester. If you're craving the ritual of a green juice, a pasteurized green juice blend or a cooked or well-processed alternative sidesteps the specific contamination concern that applies to fresh wheatgrass.
• Third trimester. Nothing changes late in pregnancy either. Fresh, unpasteurized wheatgrass juice stays in the same avoid-if-possible category as raw sprouts and juice-bar juice all the way through delivery.
