Bitters are concentrated aromatic extracts traditionally used to flavor cocktails or as digestive aids. They are created by infusing potent botanicals in a solvent, resulting in a complex, often bitter, liquid seasoning. Expectant mothers should generally avoid consuming bitters. This recommendation stems from two primary safety concerns: the presence of alcohol and the unknown effects of concentrated herbal ingredients on a developing fetus.
Understanding the Composition of Bitters
The base of nearly all traditional bitters is a high-proof alcohol solvent used to extract and preserve botanical compounds. Most commercial cocktail bitters contain 35% to 45% alcohol by volume (ABV), comparable to many distilled spirits.
The second component is a complex blend of botanicals categorized as bittering agents and aromatics. Bittering agents, such as gentian root, cinchona bark, or quassia, provide the characteristic intense bitter flavor. Aromatic spices like cinnamon, clove, cardamom, and citrus peels are added to create the product’s unique flavor profile.
The Primary Safety Concern: Alcohol Exposure
The Centers for Disease Control and Prevention (CDC) and major medical associations advise that no amount of alcohol use is known to be safe during pregnancy. This guidance is based on the risk of Fetal Alcohol Spectrum Disorders (FASDs), which can cause lifelong physical, intellectual, and behavioral disabilities.
A common bottle of bitters contains a high percentage of alcohol, even though a single serving is typically only a few dashes. While these trace amounts contribute minimally to a beverage’s final alcohol content, the medical consensus is to abstain completely. Medical professionals recommend complete avoidance because alcohol metabolism varies greatly, making it impossible to predict the exact effect on the fetus.
Herbal Ingredients and Pregnancy Risks
Beyond the alcohol content, the highly concentrated botanical extracts in bitters pose a secondary risk due to a lack of safety data. Bitters often contain herbs like wormwood, angelica root, and high concentrations of cinnamon or clove oils, which are not rigorously tested for safety during gestation. The concentration of these compounds in an extract is significantly higher than in culinary use or teas.
Certain herbs used in bitters have been historically associated with emmenagogue or abortifacient properties. This means they can potentially stimulate menstrual flow or contractions when consumed in concentrated doses. Examples of concentrated herbs that require caution include wormwood and gentian root, which are common bittering agents. Without extensive human studies, the potential for adverse effects on fetal development cannot be definitively ruled out.
The regulatory environment also contributes to the uncertainty surrounding the safety of herbal products during pregnancy. Many bitters are regulated as flavorings, which are considered “Generally Recognized As Safe” (GRAS) for the general population. However, this designation does not equate to safety specifically for pregnant women, and manufacturers are not required to conduct the same extensive testing as for pharmaceutical drugs.
Safer Alternatives for Flavoring and Digestion
Individuals seeking the flavor complexity of bitters for mocktails can look for non-alcoholic alternatives made with vegetable glycerin instead of ethanol. These glycerin-based products offer a similar aromatic profile without the associated alcohol risk. Non-alcoholic extracts, simple syrups, and fresh citrus zests can also add depth and balance to beverages.
For digestive support, safer, well-studied alternatives are available. Ginger root, in doses up to 1 gram per day, has been shown to be effective and safe for relieving pregnancy-related nausea. Peppermint or chamomile tea may also provide mild digestive relief. Pregnant individuals should consult a physician or midwife before introducing any new herbal remedy to their routine.
