Top Prebiotic Supplements for Weight Loss

Use our expert guide to pick the best prebiotic supplement for weight loss, more energy and better digestive health.

Gut Health and Your Ability to Lose Weight

Studies show that being overweight puts you at a greater risk of dysbiosis - an unhealthy balance of gut bacteria.

What’s more, researchers recently discovered overweight people lack certain beneficial bacterial strains that are abundant in lean people.

When your gut microbiome is overrun with harmful bacteria it creates a toxic environment leading to chronic inflammation.

As inflammation spreads through the body it becomes the major cause of high blood pressure, heart disease, diabetes and cancer.

As well as wrecking havoc on your immune system a gut imbalance impacts your ability to lose weight. Poor absorption of nutrients essential for metabolism cause energy levels to plummet and the release of hormones that reduce food cravings are compromised.

The bottom line is unless you can re-balance your gut bacteria you'll never be able to reduce the food cravings that are keeping you fat and putting you in greater risk of chronic disease.

6 Reasons Prebiotics Could Help You Lose Weight

More research tells us that prebiotics, not probiotics are key to restoring balance to your digestive system. And for good reason. Here's 6 of them...

  • Prevents the hunger hormone Ghrelin turning you into a binge eater
  • Produce food that feed and multiply your probiotic bacteria.
  • Nukes pro-inflammatory cytokines that weaken insulin resistance and promote fat storage.
  • Improves absorption of vitamins essential for metabolism and energy storage
  • Helps regulate the release of the fat shrinking hormone HSL
  • High fiber content of prebiotics slows down digestion time making you feel fuller for longer

How to Choose the Best Prebiotic Supplement to Lose Weight

Prebiotic supplements have boomed in recent years and the trend is set to continue as more scientific evidence reveals how essential prebiotics are to digestive health.

Prebiotic products come in either capsules are powder and both have different advantages.

With powder you can mix it in with drinks, smoothies or cereal. Capsules and pills are convenient especially when travelling.

The growing popularity of prebiotic supplements has resulted in an overwhelming choice available.

Sadly, most of these contain substandard fibers and are full of additives and bulking agents.

When choosing the best prebiotics for weight loss there are 5 key criteria to look out for.

4 Key Criteria that Influence Prebiotic Potency

Fiber Diversity

Prebiotic supplements containing only one fiber are ineffective.

Here's why...

Oligofructose is made from tiny molecules that ferment quickly in the right side of the colon. In contrast, inulin has larger molecules and ferments at a slower rate in the left colon. In order, for the whole colon to benefit you need a prebiotic supplement that contains fibers that act on the left and right side of the colon. 

Clinically Tested Ingredients:

You want prebiotics fibers that are extensively studied and show evidence that they have promoted the growth of probiotic cultures bifidobacteria and lactobacilli.

The most widely tested prebiotics are Fructo-oligosaccharide (FOS), Oligofructose-Enriched-Inulin (OEI), Galacto-oligosaccharides (GOS) and Xylo-oligosaccharides (= XOS).

Recently, acacia gum is has become a potent contender to FOS and OEI. In addition to stimulating probiotic bacteria growth, its high fiber content makes it an effective appetite suppressant and it could even help lower cholesterol levels.


Choose a prebiotic supplement that's 100% plant based, organic and free of additives.

Artificial sweeteners, fillers and bulking agents will only interfere with the prebiotics and kill off beneficial bacteria.

3rd Party Tested:

This helps to confirm accuracy of the dietary ingredients listed on the supplement facts panel and confirms that their supplements are free from certain additives and ingredients.


In a nutshell, the best prebiotic supplements deliver top grade, clinically researched ingredients at price that offers good value of for money.

It shouldn't contain easy accessible prebiotics that you can find at your local store. A supplement containing artichokes or garlic is not a good use of your money.
