The world hailed Intermittent Fasting as Ozempic before Ozempic. 

This phenomenal fad has taken the fitness world by storm over the past few years. Multiple transformative stories have been shaped by it, many doctors swear by it, and some people are suspicious of its magical effects. 

We’re not here to tear down the idea - it’s an easily implementable dietary shift that minimizes calorie consumption through eating windows. Great!

The benefits range from fat loss to metabolic flexibility, but here’s the kicker: while fasting can work wonders for your body, it can leave you nutrient-depleted if not done right. 

The solution? Supplements. Well, the right ones.

If you’re on a weight loss journey, supplements are your secret weapon to sustainably tackle your goals – keeping up energy levels, balancing your electrolytes, and ensuring your body never misses out on any essentials 

In this blog, we’re going to dive into the best supplements to help ace intermittent fasting. Ready to upgrade your fasting game? Let’s get it

Do We Need Supplements During Intermittent Fasting?

The short answer? No.

The real answer? You don’t need a knife to cut into a steak. 

But it sure as hell speeds up the process!

Zoom out and think about fasting. You're essentially giving your body a break from food for extended periods—whether that’s 12 hours, 16 hours, or even longer. While fasting, your body enters a fat-burning state, boosts insulin sensitivity, and even enhances cellular repair.

The catch? You still need nutrients to function optimally.

So while supplements are not mandatory, you better know your stuff.   

The aim is to make your fast sustainable and safe, and certain supplements can help keep your body in balance while you fast.

Top 5 Supplements To Support Intermittent Fasting

Let’s cut to the chase: during a fast, you want to stay in a fasted state, which means no insulin spikes, no calories, and no digestive processes kicking off. That said, there are several fasting-friendly supplements!

1. Electrolytes: Your Extra Edge

Fasting, especially during longer periods, can cause electrolyte imbalances, leading to headaches, fatigue, and dizziness. Sodium, potassium, and magnesium are key players here. Staying consistently hydrated with an electrolyte supplement helps maintain the balance.

• Why it matters: When you fast, your insulin levels drop, causing your kidneys to excrete more sodium and water. Taking a potent electrolyte supplement can ensure you avoid such annoying pitfalls.

• Pro Tip: Look for electrolyte supplements that are calorie-free and sugar-free to avoid breaking your fast. You’ll find one on our site.
  

2. Magnesium: Your Sleep & Stress Buddy

Magnesium is another must-have. This mineral plays a role in hundreds of bodily functions, from supporting heart health to calming the nervous system. Plus, it’s a fasting favorite because it also helps ease the cramping that can come with electrolyte imbalances. Our Max Magnesium is a fan favourite for this reason!

• Why it matters: It’s particularly helpful for people who fast regularly and want to avoid sleep issues or muscle cramps.

• Pro Tip: Magnesium Glycinate is a popular choice for its absorption and calming effects without upsetting your stomach.

3. Multivitamins: A Nutrient Safety Net

While multivitamins can be a gray area during fasting (some have small amounts of calories), taking a fasting-friendly multivitamin that doesn’t contain sugars or fillers is generally safe.

• Why it matters: Fasting reduces the variety of nutrients your body gets. A good multivitamin bridges that gap, ensuring you're not missing out on essential vitamins like vitamin D, zinc, and B-vitamins, which help with energy levels and immunity.

• Pro Tip: Opt for a whole-food-based, fasting-friendly multivitamin.

4. Green Tea Extract: Boost Fat Burn

Green tea extract contains powerful antioxidants and catechins, including EGCG, which may enhance fat-burning effects during fasting.

• Why it matters: Studies suggest that EGCG increases fat oxidation, helping you burn more fat in the fasted state.

• Pro Tip: Drink green tea or take a green tea supplement during your fast. Just make sure it’s in a pure form without added sugars or calories.

5. Probiotics & Prebiotics: Keep The Gut Happy

Gut health is crucial during fasting, as long periods without food can alter gut bacteria. Probiotics help maintain healthy gut flora, while prebiotics feed the beneficial bacteria.

• Why it matters: Healthy gut bacteria can improve digestion, mental clarity, and even fat metabolism—all while you’re fasting.

Tips On Staying Full For Longer

Before diving deeper into supplements and fasting, it’s important to understand what to actually EAT in between your fasting windows. 

Because supplements can help here too! 

The math is simple: load up on protein + fiber. 

Protein shakes (like our premium plant protein range) or diets heavy in protein are an excellent way to feel fuller for longer. So load up on protein. 

Secondly, nail your fiber intake, which most of the world really doesn’t.  Potent fiber also helps you feel fuller for longer while aiding digestion so you definitely don’t want to skip it in meals. If you’re searching for a smart supplement here, our Fenulean Trim Tonic ® will work perfectly.  

The Best Supplements For Your Eating Window

While the previous list helps you during your fast, there are also supplements that work best when taken during your eating window, enhancing the benefits of fasting:

• Omega-3 Fatty Acids: To support heart health and reduce inflammation. Our 4x Strength Outshine Omega-3 works well.  

• Vitamin D: Especially for those fasting in low-sunlight areas or during winter months.

• Protein Powder: For muscle repair and recovery after workouts.

Final Thoughts: Enhancing Your Fast

The right supplements can elevate your intermittent fasting experience from "surviving" to "thriving." Whether you’re fasting for mental clarity, fat loss, or just a reset, the key is to keep your body balanced. 

From electrolytes to magnesium, green tea to probiotics, these supplements will help you get the most out of your fasting routine.

Remember: fasting doesn’t mean starving your body of everything. It’s about balance—and supplements help fill the gaps wherever needed.

Stay sharp, stay balanced, and fast smarter, not harder.

The Bottom Line

The best supplements for intermittent fasting depend on your specific needs—whether it’s electrolytes for hydration or green tea extract for fat burning. Choose supplements wisely to enhance your fast without breaking it, and always listen to your body. Happy fasting!
