Is It Safe to Drink Apple Cider Vinegar While Pregnant?

We don't recommend it. Find out why in this article.

Alongside green smoothies and kombucha, apple cider vinegar is one of the most popular drinks among wellness enthusiasts these days.

Many claim that drinking apple cider vinegar prevents indigestion and leg cramps, which, if you are pregnant, may sound all-too-familiar.

But is it safe to drink apple cider vinegar during pregnancy?

In this article, we’ll outline our position on apple cider vinegar during pregnancy. We’ll explain the reasons for our stance and list its benefits, risks, and the science behind it all, to help you make an informed decision.

Key Takeaways

  • Apple cider vinegar (ACV) is made from apple juice or cider mixed with yeast, which ferments the sugars in the fruit, forming alcohol, and then more bacteria are mixed with the alcohol, turning it into acetic acid.
  • There are two types of ACV, unfiltered and filtered, and it can also be pasteurized or unpasteurized. Unfiltered and unpasteurized ACV contains sediment and beneficial bacteria called “the mother” which is believed to be responsible for most of the health benefits.
  • Consuming ACV during pregnancy should be done with caution. ACV can cause heartburn, trouble with digestion and it is best to avoid unpasteurized ACV during pregnancy.
  • Pregnant women should consult with their healthcare provider before consuming ACV.

What Is Apple Cider Vinegar?

Apple cider vinegar (ACV) is essentially apple juice or cider mixed with yeast, which ferments the naturally occurring sugars in the fruit, forming alcohol.

After the initial fermentation, more bacteria are mixed with the alcohol, turning it into acetic acid (1).

Types Of Apple Cider Vinegar

There are two basic kinds of ACV – unfiltered and filtered. ACV can also be pasteurized or unpasteurized.

Processing removes sediment and bacteria to make filtered and pasteurized apple cider vinegar, respectively. Typically, filtered ACV is also pasteurized. The product is a clear, amber-toned liquid.

Pasteurization refers to mildly heating the ACV to destroy live bacteria (2). The process of filtration, though, involves removing sediment.

Unfiltered apple cider vinegar does not undergo additional filtration, so it may be cloudy due to the sediment and “the mother.” And often, unfiltered ACV is also unpasteurized — just raw.

“The mother” is a mixture of acetic acids and beneficial bacteria that occurs naturally in the fermentation process. It’s a strand-like residue in the vinegar and is believed to be responsible for most of the health benefits.

One of the most well-known brands of unpasteurized apple cider vinegar is Braggs. It is widely available in health stores and on Amazon.

What To Know About ACV

Health and wellness enthusiasts believe apple cider vinegar is beneficial for a variety of ailments.

Keep In Mind

Some of these claims are more stories than anything else as they haven’t been proven in scientific studies, but others are backed by medical research. So, take ACV information with a grain of salt, and don’t hesitate to check with your healthcare provider when in doubt.
  • Diabetes: Scientific studies have shown ACV can lower blood sugar levels and improve insulin sensitivity when consuming certain foods. Still, you should only use it for blood sugar control under the guidance and supervision of your doctor. This is especially important if you are already taking blood sugar-lowering medications. ACV can help with blood sugar control but not replace the therapy your doctor prescribes (3).
  • Digestion: When consumed regularly, apple cider vinegar can also help detoxify your body. It contains probiotics that support gut health, improve bowel function, and balance your body’s pH levels. Optimal pH balance and gut health can relieve conditions such as constipation and acid reflux. It is thought that taking 1-2 tablespoons of ACV in a big glass of water can help with morning sickness or nausea, but there is no scientific proof for this (4). Nevertheless, there’s a possibility that ACV can actually cause heartburn and trouble with digestion, especially digestion of starch-rich ingredients like potatoes. Either way, make sure to avoid unpasteurized ACV during pregnancy.
  • Weight Loss: When consumed before meals, ACV helps you feel full, so you may eat less and keep your calorie intake down. However, pregnancy isn’t the time to diet or try to lose weight. Instead, focus on eating a diet of well-balanced, nutritionally dense foods to nourish yourself and your growing baby.
  • Common Cold: Many pregnant women are uncomfortable taking over-the-counter medications for cold and sore throat symptoms. Since ACV has immunity-boosting and antibacterial properties, it could be an option to fight these symptoms. You can make a soothing drink by mixing one part ACV, five parts warm water, and 2-3 tablespoons of honey. Still, make sure to avoid unpasteurized ACV during pregnancy, and if you want to avoid drinking it altogether, you can try making an ACV gargle for your sore throat (5).
  • Leg Cramps: Sleep disruption due to leg cramping is common in pregnancy. This may be caused by low potassium levels and pressure on the circulatory system from the growing uterus. ACV is high in potassium can help alleviate this discomfort.

In addition to consuming apple cider vinegar, many people also use the substance topically — for everything from dandruff treatment to foot deodorizers!

Thanks to its antibacterial and anti-inflammatory properties, these common pregnancy skin concerns might benefit from a small amount applied topically:

  • Warts.
  • Varicose Veins.
  • Eczema and Acne.

If you have varicose veins, you can use ACV as an add-on to conservative treatment, such as elevation. Just make sure you don’t apply it to broken skin (6).

Still, ACV is a weak acid, and it can cause skin irritation. So, if you decide to apply it to your skin, make sure you use small doses (always use it diluted: two parts ACV to one part water). Apply it first to a small part of your skin (this also helps check for an allergic reaction), and don’t keep it on too long. If it starts feeling uncomfortable beyond a slight burning sensation, remove it right away. Never use it on open wounds or genital warts (7).

While there is a lot of talk about the health benefits of ACV, it’s worth noting that ACV can interact with certain medications (including laxatives, which some moms with constipation might be taking). It can make symptoms of a pre-existing ulcer worse and can affect teeth enamel. Consuming too much can also cause serious electrolyte disbalances.

A Word Of Caution

Healthcare professionals recommend pregnant women should avoid consuming unpasteurized foods due to the risk of food poisoning. No proven or assumed health benefits can outweigh the possible health risks for you and your baby.

Unpasteurized apple cider vinegar — which is often unfiltered — still contains the “mother,” along with potentially beneficial enzymes and bacteria.

Important To Remember

Pregnant women are at a higher risk for foodborne illnesses due to hormonal changes and lowered immune system function. This is one reason to avoid unpasteurized foods. Remember that while you are pregnant, your baby still does not have a fully developed immune system, and some of the bacteria can cross the placenta.

Symptoms of food poisoning can be flu-like, including fever, muscle aches, nausea, vomiting, and diarrhea. Headaches, stomach pain, and dehydration can also occur.

However, there are foodborne illnesses such as listeriosis, toxoplasmosis, or salmonellosis, which not only affect mom but can cause serious complications for the unborn baby (8). The bacteria causing listeriosis, toxoplasmosis, or salmonellosis might not be in all unpasteurized apple cider vinegar, but the risk is present.

That’s why it is important for mom-to-be to consult her doctor or midwife to decide if she should consume ACV during pregnancy and get advice on the product choice.

You may wonder whether pasteurized ACV still has the potential to aid with the above-listed health issues. The truth is, research studies have not been able to confirm whether all potential benefits of ACV are lost after pasteurization.

ACV Use In Pregnancy

Apple cider vinegar may be a hot wellness trend, but it might not be right for you, especially during pregnancy.

Claims that apple cider vinegar can cure a wide variety of ailments are promising. However, many have yet to be scientifically proven. We need more research to confirm all of its risks and benefits.

Until then, rest, try to enjoy your pregnancy — despite the discomforts, and take the cure-all apple cider vinegar claims with a grain of salt.
