Find Your Health Zen


Intermittent fasting, a popular diet trend for weight loss and overall health enhancement, involves abstaining from food for an extended period. While fasting can offer numerous benefits, such as improved insulin sensitivity and increased fat burning, it is crucial to ensure that you are still getting the necessary nutrients during this restricted eating window. This is where supplements come into play. In this article, we will explore the best time to take supplements during fasting and discuss some specific supplements that can support your overall well-being.

The Best Time to Take Supplements

During fasting, it is essential to time your supplement intake strategically to maximize their benefits. The ideal timing may vary depending on the type of supplement and your specific health goals. Here are some general guidelines:

  1. Creatine: Creatine is an amino acid powerhouse that supports muscle growth and enhances exercise performance. It is recommended to take creatine either before or after your workout, regardless of whether you are fasting or non-fasting. This ensures that your muscles receive the necessary fuel for optimal performance.
  2. CBD and MCT Oils: CBD and MCT oils are popular supplements known for their potential benefits in reducing stress and promoting relaxation. It is best to consume these oils during your eating window to aid with digestion and absorption.
  3. Amino Acid Supplementation: Amino acids play a crucial role in various bodily functions, including cognitive performance and emotional well-being. One amino acid that can help combat fatigue and stress is L-tyrosine. It can be taken in the morning on an empty stomach to boost dopamine, adrenaline, and norepinephrine levels.
  4. Electrolyte Supplements: Electrolyte imbalances can occur during fasting, leading to fatigue, muscle cramps, and dehydration. Supplementing with electrolytes like magnesium can help maintain proper fluid balance and support muscle function. It is best to take electrolyte supplements with water, preferably during your eating window.
  5. Curcumin: Curcumin, the active compound in turmeric, possesses potent anti-inflammatory and antioxidant properties. Taking curcumin with a source of fat, such as fish oil or avocado, can enhance its absorption. Consider consuming curcumin during your eating window for optimal benefits.
  6. Probiotics: Probiotics are beneficial bacteria that support gut health and promote digestion. To maximize their efficacy, it is recommended to take probiotic supplements with a meal during your eating window.

Who Should Avoid Certain Supplements?

While supplements can be beneficial for many individuals, certain populations should exercise caution or avoid specific supplements altogether. It is important to consult with a healthcare professional before starting any new supplementation regimen, especially if you have:

  1. Chronic Heart Conditions: Individuals with chronic heart conditions should take precautions with certain supplements, such as excessive caffeine or stimulants, as they may worsen heart symptoms.
  2. Kidney or Renal Issues: Some supplements may put additional strain on the kidneys. People with kidney or renal issues should avoid supplements that could potentially worsen their condition.
  3. Food Disorders: Individuals with food disorders should seek guidance from healthcare professionals to ensure the safe and appropriate use of supplements during fasting.
  4. Difficult-to-Control Diabetes: People with diabetes may need personalized advice regarding specific supplements that can help manage their condition effectively and safely during fasting.
  5. Children, Seniors Above 70, Pregnant, and Lactating Women: These populations have unique nutrient needs and should consult their healthcare providers before introducing any new supplements.
  6. People Recently Discharged from the Hospital: Post-hospital discharge, it is crucial to follow healthcare professionals' guidelines regarding supplement intake, as certain supplements may interfere with medications or recovery processes.


While intermittent fasting can have numerous health benefits, it is essential to prioritize nutrient intake during the fasting window. Taking supplements strategically can help bridge the nutrient gaps and support your overall well-being. Ensure you consult with a healthcare professional before incorporating new supplements into your fasting routine, especially if you fall into any of the above-mentioned population groups. By properly timing and selecting supplements, you can optimize your fasting experience while nourishing your body with the necessary nutrients.
