Top 5 Intermittent Fasting Supplements

#1 Branched Chain Amino Acids (BCAAs) Supplements

There’s a lot of broscience about branch chain amino acids going around forums, etc.

As a result, there have been some people saying “Branch chain amino acids don’t work”. Well, that’s not exactly the truth, bro, especially when it comes to intermittent fasting and the fasting supplements you can take for your body when combined with adequate protein.

Alright, so it may be true that taking branch chain amino acids alongside a super high protein diet might not be worthwhile when trying to gain muscle mass. But you’re probably not trying to gain muscle mass while following an intermittent fasting diet while also not having to break your fast.

Chances are your main aim is the be in a calorie deficit to reduce body fat and increase muscle definition which is why you chose a diet like intermittent fasting in the first place. And this is where branch chain amino acids have shown to be particularly useful in clinical studies and are good supplements to take alongside solid protein sources.

A study conducted in the Journal of the International Society of Sports Nutrition found that “BCAA supplementation in trained individuals performing resistance training while on a hypocaloric diet can maintain lean mass and preserve skeletal muscle performance while losing fat mass”.

In plain English, the above conclusion means that: Branch chain amino acids can save you from losing your hard-earned muscle mass while in a calorie-deficit aiming to reduce body fat making it a good intermittent fasting supplement and a strong contender for supplements to take while fasting when combined with solid protein.

Top Recommended BCAA: Performance Lab BCAA

Finding a clean, high quality BCAA isn’t as easy as it sounds but something you need. You don’t want to just grab the first product, like fasting supplements, you see on the shelves of your local store because you want to ensure it helps with the benefits.

You might be disgusted to hear that many products on the market use pig fur or duck feathers as their amino acid sources which are reasons enough to break your fast.

That’s not a lie. In fact, a clinical study published in the American Journal of Food Sciences confirmed the above to be true and you don’t need that in any supplement let alone one for intermittent fasting because the supplements to take are ones to help you and helps your overall goals.

That’s why we use Performance Lab BCAA; it’s a completely vegan-friendly supplement great for intermittent fasting that sources its amino acids from AjiPure® which is found to be up to 6x purer than other amino acids brands. The magic is due to AjiPure® being combined with cutting edge NutriGenesis® technology, resulting in the most bioavailable BCAA we’ve seen.

Performance Lab BCAA also comes in capsules, so It doesn’t contain any artificial flavors or colors – making it the cleanest and highest quality product we’ve tested.

#2 Fat Burner Supplements

We’ve said this a couple of times already. If you’re following an intermittent fasting diet, then you’re end goal is most likely to lose body fat and fat burning supplement are great aids to help.

So, naturally, a fat burner supplement will be high on your priorities so you can see weight loss and not break a fast which are important.

But not just any burner. A fat burner that contains ingredients to further help protect your muscle mass while in a calorie deficit and aid in intermittent fasting diets so you don’t have to break your fast and leave your fasted state.

Because let’s be honest. You don’t need a burner supplement to lose body weight…simply being in a calorie deficit will get the job done. So remember that no burner supplement is a magic pill although it can work as a fasting supplement.

But what an effective fat burner should do is promote fat loss further while protecting muscle mass during fasted training – to make it perfectly suited to an intermittent fasting diet.

…and that’s exactly what Performance Lab Burn is made for.

Top Recommended Fat Burner: Performance Lab Burn

The main benefit that this burner offers is that it “helps you lose fat and keep muscle”. For us, that’s exactly what a fat burner should do – after all, no-one wants to lose hard-earned muscle mass while trying to get shredded, especially if in a diet like intermittent fasting.

To deliver this, Performance Lab Burn contains HMB; a clinical study concluded that HMB “promotes an advantageous reduction of fat mass and increase in fat-free mass”.

In order to help you burn more fat than you would normally, it contains many tried-and-tested thermogenics such as cayenne pepper extract, a staple in an intermittent fasting supplement. Which has proven to boost your metabolic rate in numerous studies (in fact, there is actually a study titled “capsaicinoids supplementation decreases perfect body fat and fat mass” to prove our point).

We appreciate that Performance Lab Burn is a science-backed fat burner and not just fueled on unproven claims.

#3 Caffeine Supplements

It’s pretty well known that many people like drinking coffee while in the fasting stage of their intermittent fasting days and also for a pre workout boost and energy.

There’s nothing really wrong with coffee. And to be honest, nothing is going to stop coffee-lovers from drinking coffee and caffeine works to kickstart your metabolism and act as a natural fasting supplement great for weight loss which is important.

In fact, the good news is that caffeine consumption doesn’t officially break a fast (unless you follow that sh*tty trend and add butter to your coffee – since that will break your fast).

However, we bet you didn’t know that caffeine consumption depletes B-Vitamins. Well now you do but there are fasting supplements and ways to work around this with intermittent fasting so you take supplements while fasting to help you.

Here’s where a caffeine supplement containing B-Vitamins can come in…

Top Recommended Caffeine Supplement: Performance Lab Stim

Heard about nootropic supplements? They’re supplements that are capable of improving your cognition (helping you to think clearer and perform better mentally).

Well, Performance Lab Stim is a next-gen caffeine pill that can also be classed under the “nootropic” category of fasting supplements and will prove to be one of the better supplements while fasting to see gains.

As well as delivering clean, natural caffeine, it also provides you with all the B-Vitamins that caffeine depletes in the exact quantities it depletes them in – helping to keep you fueled nutritionally and on a solid intermittent fasting plan.

The cherry on-top is the addition of L-Tyrosine, one of the most clinically backed nootropic ingredients to further improve your cognition.

In summary, this is an advanced caffeine supplement that you can take as a coffee alternative or to give you a clean energy boost for fasted workouts. Performance Lab Stim is also designed to stack safely with their non-stim fat burner and other products.

#4 Prebiotic Supplements

Gut health is something that’s seriously overlooked when it comes to fitness and overall health and can be really enhanced by an intermittent fasting supplement.

We bet you didn’t know that a prebiotic supplement can actually promote fat loss and strengthen your immune system, did you? These are some of the reasons to commit to intermittent fasting after all keeping you in a fasted state.

In fact, a clinical study states that “almost 70% of the entire immune system” is located in the gut.

Top Recommended Prebiotic Supplement: Performance Lab Prebiotic

Performance Lab Prebiotic has made use of the nutritional technology available when it comes to gut health providing a high quality fasting supplement.

Containing Orafti® Synergy1, which has shown to have a positive effect on immune system in numerous studies, it’s also free from allergens, gluten, soy, synthetic additives which are all good signs from a quality fasting supplement for health benefits.

It’s also completely vegan-friendly, with its capsules being made from prebiotic fiber. Making it the cleanest prebiotic on the market and great fasting supplement, in our honest opinion.

#5 Multivitamin Supplement

Multivitamin supplements are arguably the most underrated in the industry. They kind of get a bad reputation from the really cheap supplements that turn your pee yellow, but are very useful when dieting like intermittent fasting where many nutrients are lost or not received.

Trust us, though. Multivitamins can offer a lot more benefits than changing the color of your urine…

When intermittent fasting, you’re having one or two less meals than you would normally (by skipping breakfast). And, more often than not, intermittent fasters are in a calorie deficit too since they often aim to lose body fat which can effect energy levels and allow for inadequate nutrients.

As a result, intermittent fasters need to obtain all their nutrients in less meals (and calories) than normal; to put that into perspective, people not keeping an eye on their calories often don’t consume the recommended amounts of vitamins and minerals which can hurt their goals of ultimate health benefits.

Therefore, multivitamins provide great “nutritional insurance” to make sure you do obtain all essential nutrients for peak health so you thrive with a fasting supplement for weight loss and the best benefits.

Top Recommended Multivitamin Supplement: Performance Lab NutriGenesis® Multi

What sets this multivitamin apart is Performance Lab’s own patented NutriGenesis®  technology; they are able to produce “nature-identical” vitamins and minerals (completely with co-factors) that your body recognizes and absorbs as actual food so all the nutrients you miss out from an intermittent fasting diet reach your body to help you lose weight and keep your energy levels high.

The result? A next-gen multivitamin that actually improves your general health and provides for one of the better supplements while fasting to help you.

Performance Lab NutriGenesis® Multi delivers over at least 100% of the daily recommended values of over 17 essential vitamins and minerals too, giving you a great fasting supplement.

It’s also extremely clean too, being free from allergens, gluten, soy, synthetic additives, GMOs – and it’s also banned substance tested too.

Without a doubt (in our honest opinion) the cleanest and highest quality multivitamin on the market and a great fasting supplement aid for those looking to take supplements.

Wrap It Up

Intermittent fasting isn’t for everyone. But we’re guessing that you’re someone who enjoys skipping breakfast since you’re reading this article and are looking to take supplements to help.

The fact is that most people who follow an intermittent fasting diet are aiming to lose body fat/weight. Since this requires you to be in a calorie deficit, you have the challenge of consuming all nutrients that you need in fewer meals and fat soluble vitamins can help.

Intermittent fasting supplements such as multivitamins will help provide you with nutritional insurance, so you don’t have to worry (as much) about getting the right vitamins or minerals through your meals and fasting period.

Supplements such as BCAAs will then help protect your hard-earned muscle mass while you’re in a calorie deficit too by providing you with solid ingredients.
