Do Supplements Promote Intermittent Fasting?

Supplements promote intermittent fasting by treating dietary shortages, helping with hunger control, giving energy, promoting gut health, and maybe increasing metabolism and fat loss. But it’s necessary to remember that dietary supplements shouldn’t always be seen as a substitute for a healthy diet and an active way of life.

While supplements can support intermittent fasting, their effectiveness will depend on how each individual responds to them. The best course of action is to consult with a medical professional to find out which supplements are appropriate for your unique needs and fasting-related goals.

Do Supplements Break a Fast?

Calorie, carbohydrate, or protein-containing supplements can break a fast and disturb the fasting state. This is because ingesting these foods defeats the objective of fasting by inducing metabolic processes and influencing insulin levels.

A fast is likely to be broken by supplements like multivitamins with additional sweets or fillers, protein powders or meal replacement drinks, and specific calorie-rich, fat-based supplements. These dietary supplements deliver nutrients that can trigger insulin release, ending the fasting state.

However, some supplements are typically regarded as fasting-friendly since they have low to no calorie, carbohydrate, or protein content. For instance, simple water, mineral supplements without extra calories or sweets, electrolyte supplements without added sugars and non-nutritional supplements such as caffeine tablets or herbal teas without added sugars.

It’s vital to remember that different fasting regimes could have different supplement requirements. Additionally, many circumstances, including the exact supplement contents, the length and kind of fasting, and individual physiological reactions, might affect how supplements affect fasting. 

Which Supplements can Break Your Fast?

  • Protein Powder Supplements: Most protein powders have a single serving of roughly 15 grams of protein, 100 calories, and 5 grams of carbohydrates. Any calorie-containing substance will end fast. Protein supplements are frequently employed to increase muscle mass and facilitate post-workout recovery from exercise. 
  • Gummy Vitamins and Supplements: Gummy vitamins and supplements are frequently prepared with extra sugar, calories, and ingredients like collagen and gelatin, that result in ending a fast. Supplements with coatings or additions can additionally end a fast.
  • Herbal Supplements: A few herbal or dietary supplements might include caloric components that could impact insulin sensitivity. Supplements containing additional sugars, syrups, or other high-calorie components are a few examples. It’s essential to read the description and select supplements believed to be calorie-free or specially designed for fasting.
  • MCT Oil: Although MCT oil contains calories and is abundant in coconut oil, it breaks down differently than other kinds of fats. Because MCT oil does not boost the body’s insulin synthesis, it is unlikely to affect how well the human body burns fat. While breaking your fast with MCT Oil won’t immediately affect the health advantages of intermittent fasting, it constitutes a high-calorie snack.

What Supplements can Prevent You from Breaking Your Fast? 

Due to their often low or absent calorie, carbohydrate, or protein content, certain supplements are less likely to disrupt a fast. These consist of the following:

  • Electrolyte Supplements: Electrolyte supplements for fasting are typically safe because they don’t include calories or sweets. They can support electrolyte balance maintenance and guard against deficits.
  • Plain Water: Keeping hydrated during fasting is essential, and drinking plain water has no substantial calories or nutrients that might interfere with the fast.
  • Black Coffee: The query “does coffee break a fast” concerns many individuals. So, since coffee has few calories and has little effect on insulin levels, it is typically not thought to break a fast, especially black coffee, without any sweets or additions. It’s crucial to remember that putting cream, sugar, or other high-calorie additions to your coffee will ruin your fast.
  • Green Tea: Due to its low-calorie content and potential health advantages, unsweetened green tea is another favorite beverage during a fast.
  • Herbal Tea: Many herbal teas, including chamomile or peppermint tea, are considered safe to consume while fasting because they don’t have any calories or caffeine.
  • Healthful Fats: Throughout the fast, specific individuals sip coffee that contains MCT oil, ghee, coconut oil, or butter. Oil may keep you going until your next meal while breaking a fast yet keeping you in ketosis.
  • Bone Broth: This abundant nutritional source can aid in replacing electrolytes depleted while merely drinking water for extended periods.
  • Apple Cider Vinegar: Some individuals discover that consuming water diluted with 1-2 teaspoons (5–10 ml) of vinegar made from apple cider will help them keep hydrated and curb appetites when fasting.

These supplements don’t significantly affect insulin levels or activate critical metabolic processes. Thus they are typically classified as fasting-compatible. It’s crucial to remember that everyone reacts to these supplements differently and that some fasting programmes may have particular rules on utilizing them.


As we are near the end of our investigation on do supplements break a fast, it becomes apparent that different supplements have different impacts on how quickly you can break a fast. Others with little or no calories, like electrolytes and simple water, are less likely to break a fast, although other supplements containing calories, carbs, or proteins can. It’s critical to realize that every person reacts differently and that different fasting programmes may have different supplement recommendations.
