Let’s explore the probiotic supplements in the table above and find out what they have to offer.

#1. Performance Lab Prebiotic: The Best Probiotic Supplement 2020

Performance Lab Prebiotic is unrivalled in the prebiotic supplements world. It boosts the levels of a group of gut bacteria called Bifidobacterium. The bacteria help the body to break down dietary fibre and enhance the uptake of minerals and nutrients into the bloodstream.

Performance Lab Prebiotic is not only boots probiotics but also supplies soluble fibre to your body. The soluble fibre helps to enhance metabolic and microbiome functions.

To better understand how Performance Lab Prebiotic works, let’s explore its ingredients.



The main ingredient in Performance Lab Prebiotic is Inulin-FOS. Inulin-FOS is extracted from chicory root. Inulin-FOS is known to have a high dietary fibre content. It boosts the existing probiotics in your body. It causes them to grow, develop, and multiply. The result is more stable and reliable microbiome functions. Inulin-FOS also has high dietary fibre content. Dietary fibre plays a lot of important roles in the stomach.

Other ingredients include;

  • Pullulan
  • Rice Concentrate

Pullulan is found in the NutriCaps capsules that hold the actual supplement. Pullulan is a low-calorie food additive. It helps to retain the performance lab prebiotic supplement longer in the stomach.  Pullulan is low-digesting and will stay in the stomach for longer.  That way, more probiotics find a way to attach themselves to the stomach.

Rice concentrate is simply ground rice hulls. It is used as the base for the prebiotic supplement. It plays a similar role to that of pullulan.

How Performance Lab Prebiotic Works

Performance Lab Prebiotic is a cut always a cut above other probiotic supplements. Its action touches on the following body functions.

  • Digestion – The probiotics group known as Bifidobacterium finds their way into the intestines. They help to enhance digestion and metabolism. The result is better food breakdown, and more nutrients intake. The bacteria contribute to the production of enzymes that are used to breakdown foods and nutrients.
  • Pathogen resistance – We’ve mentioned that Inulin-FOS is the main ingredient. When fermented in the gut, it produces lactic acid and slightly increases the acidity levels. Bad bacteria cannot thrive in an acidic environment. Pathogens such as coli and Candida albacans are eliminated.
  • Immunity – Enhanced probiotics promotes the proliferation and synthesis of immune cells. Immune cells such as macrophages and lymphocytes are activated. They then stay on standby to provide defence whenever it’s required.
  • Nutritional status – The slightly acidic environment promotes the uptake of minerals and nutrients into the bloodstream. Essential minerals such as iron, magnesium, calcium are properly synthesized.
  • Heart health – We’ve mentioned that you get a lot of dietary fibre from Inulin-FOS. The fibre helps to bind cholesterol in the stomach. It prevents its uptake into blood vessels. The cholesterol is then flushed out of the system during excretion.
  • Weight control – Inulin-FOS suppresses a hunger hormone known as ghrelin. You end up feeling less hunger, but the little you take is utilized efficiently.
