For instance, antacids that contain sugar may cause an insulin response, which could break your fast.

Antacid Vs. Other Medications

Compared to other medications, antacids are generally considered safe to take during intermittent fasting. However, some medications, such as antibiotics or prescription medications, may need to be taken with food, which could break your fast. It is important to consult with your healthcare provider before taking any medication during intermittent fasting.


In summary, antacid does not contain any calories and does not break intermittent fasting. However, some types of antacid may contain sugar and other additives that could have an impact on your fasting goals. If you are uncertain about the ingredients in your antacid, it is best to consult with your healthcare provider or a registered dietitian. Remember, the key to successful intermittent fasting is to stay consistent and committed to your plan.

Frequently Asked Questions

Intermittent fasting has become a popular dieting trend for weight loss and overall health. However, many people are still confused about what breaks a fast and what doesn’t. In this article, we will answer some common questions about whether antacids break intermittent fasting.

What are antacids?

Antacids are medications that help relieve heartburn, acid reflux, and indigestion. They work by neutralizing stomach acid, which can help reduce symptoms. Common types of antacids include calcium carbonate, magnesium hydroxide, and aluminum hydroxide.

While antacids can be helpful for managing digestive issues, they may have an impact on fasting. Some antacids contain sugar or other additives that could break a fast. It’s important to read the label and talk to your doctor if you have any concerns.

Can I take antacids during intermittent fasting?

Technically, taking antacids during intermittent fasting will break the fast. However, the impact on your overall progress will depend on how strict you are with your fasting regimen. If you are doing intermittent fasting for weight loss, taking antacids may not have a significant impact on your results.

However, if you are fasting for other health benefits, such as improved insulin sensitivity or autophagy, it’s best to avoid taking antacids during your fasting window. Instead, try to manage your symptoms with lifestyle changes or natural remedies.

What are some natural remedies for heartburn and acid reflux?

If you are experiencing heartburn or acid reflux during your fasting window, there are several natural remedies you can try. Drinking water or herbal tea can help soothe the digestive system and reduce symptoms. Chewing gum can also stimulate the production of saliva, which can help neutralize stomach acid.

Avoiding trigger foods, such as spicy or fatty foods, can also help reduce symptoms. Additionally, practicing stress-reducing techniques, such as meditation or deep breathing, may help manage symptoms caused by stress.

How long should I wait to take antacids after breaking my fast?

If you do need to take antacids after breaking your fast, it’s best to wait at least an hour before doing so. This will give your body time to digest your meal and resume normal digestive function. Taking antacids too soon after breaking your fast may interfere with your body’s natural digestive process.

It’s also important to note that if you are taking any medications or supplements, you should talk to your doctor before starting intermittent fasting or taking antacids.

What are the potential side effects of taking antacids?

While antacids are generally considered safe, they may have some side effects. Common side effects of antacids include constipation, diarrhea, and stomach cramps. Long-term use of antacids may also affect the absorption of certain vitamins and minerals, such as calcium and vitamin B12.

If you are experiencing any side effects from taking antacids or have concerns about their impact on your fasting regimen, talk to your doctor.

Do NOT Take These Supplements When Fasting (please trust me on this)

In conclusion, while antacids may contain calories and therefore technically break a fast, they are unlikely to have a significant impact on your overall fasting goals. If you are using intermittent fasting primarily for weight loss, taking an occasional antacid is unlikely to derail your progress.

However, it is important to note that some antacids may contain ingredients that are not recommended during a fast, such as artificial sweeteners or preservatives. It is always best to consult with a healthcare professional before incorporating any new medications or supplements into your fasting routine.

Ultimately, the decision to take antacids during a fast is a personal one that should be made based on your individual needs and goals. By staying informed and paying attention to your body’s responses, you can make the best choices for your health and well-being.
