Can You Take Supplements While Fasting: Fasting or “skip a day” feeding sharpens your concentration, burns off body fat, and increases your metabolism. When someone fasts, they refrain from eating for a prolonged time. But it’s essential to think about taking supplements while fasting. Contrary to popular belief, some fasting supplements can actively encourage your body to burn calories for energy.

The science underlying how each nutritional supplement works is explained, along with which ones you should use and which ones you should avoid.

How and When You Can Take Supplements While Fasting?

Can You Take Supplements While Fasting? The answer is yes. All intermittent fasting supplements should be consumed on an empty stomach in order to avoid breaking a fast. Be mindful of how you feel and follow these recommendations.


  • Either through fasting, detoxing, or dieting for fat loss, restriction of daily meals can result in vitamin shortages. Supplementing your fast can help restrict this deficiency and maintain your energy when fasting. 
  • Choose supplements consisting of creatine monohydrate, essential amino acids, and electrolytes to support energy levels and provide quicker recovery for muscles.

Can You Take Supplements While Fasting: What Supplements Can Be Taken? 

Below is a list of supplements you can consume while on an intermittent fast. 

  • Probiotics: Your entire body benefits from healthy gut microbes, which are suitable for health. One should consume most probiotic pills without meals during low stomach acid. For instructions from the manufacturer, look at the label of your probiotic product.
  • Creatine: Since it has no calories and has no effect on insulin sensitivity, creatine will not break your fast whether you consume it before or after exercise.
  • Electrolytes: Taking an electrolyte supplement during a fast is acceptable as long as it doesn’t feature any sugars or carbohydrates. Potassium, sodium, and calcium are examples of electrolytes.
  • Essential Amino Acids: The benefits of taking essential amino acids during a fast, especially if exercising, far outweigh the risks of breaking your fast. During exercise these EAAs will help with lean muscle retention, enhanced recovery, and help decrease soreness. EAAs will also help reduce mental and physical fatigue.

Can You Take Supplements While Fasting on an Empty Stomach?

Some supplements should not be consumed during a fast on an empty stomach. Below is a list of those supplements.

  • Curcumin and omega-3 fatty acids: Whenever consumed with food, supplements like Curcumin and Omega -3 Complex are more easily absorbed by your body. So, consume them within your period of eating.
  • Fat-soluble vitamins: Vitamins that dissolve in fat are vitamins A, D, E and K. Take these vitamins with food because they won’t disintegrate in water.
  • Gummy vitamins: Gummy vitamins are likely to break your fast since they are typically flavored and produced with gelatin, which encodes a protein. They are also usually made with a form of sugar which will break your fast.
  • Iodine: Swallow potassium iodide tablets or kelp powder with meals for optimum absorption.
  • Magnesium: Consuming a magnesium pill on an empty stomach may cause stomach aches in some individuals.
  • Protein powder:  Protein powders break fast because they are calorie-rich and provoke an insulin reaction. Reserve your powders for the time you will be eating.
  • Copper and zinc: Since these two minerals combine better, they are frequently found in tablet form and taken with food.

The Science Behind: Can You Take Supplements While Fasting?

Abstain from eating everything which disrupts your fast if you want to reap the full health advantages of intermittent fasting. That covers all calorie-rich foods, drinks, and nutritional supplements that speed up digestion or raise insulin sensitivity.


  • Long durations of fasting encourage autophagy, the mechanism by which your cells eliminate accumulated garbage.
  • For your body to work, you need energy. The metabolic state of ketosis, in which fat is burned as fuel, is facilitated by fasting. When you miss meals, your body first uses the banked glucose before switching to burning fat.
  • Fasting may also trigger the release of a specific protein, fasting-induced adipose factor (FIAF), which tells your body it’s time to start burning fat.

To sum up, you should exercise caution while taking supplements since some of them will lead you to violate your fast. While some won’t automatically end your fast, others shouldn’t be consumed on an empty stomach.
