The Basics

What Exactly Is a Postbiotic?

Probiotics are live bacteria. Prebiotics feed them. Postbiotics - the third, most advanced category are the bioactive compounds bacteria produce. A probiotic is a seed. A prebiotic is the soil. A postbiotic is the fruit: the finished product that delivers the benefit directly. Biomewise's HK L-137 is the most extensively studied postbiotic in existence - stable, unaffected by stomach acid, effective from day one.

The Problem

Why Your Probiotic
Probably Isn't Working

  • Stomach Acid

    Most probiotic bacteria are destroyed by stomach acid before they ever reach the intestines. Studies suggest up to 99% of probiotic bacteria in standard supplements die in transit.
    Problem 1

  • Colonisation

    Even if bacteria survive, they must establish a colony in your gut to have any effect. This is a slow, uncertain process that may never fully occur in many individuals.
    Problem 2

  • Inconsistency

    Live bacteria in supplements degrade over time, especially without refrigeration. The potency you see on the label may not be what you're actually consuming.
    Problem 3

Postbiotics solve all three problems. They're already active. They don't need to colonise. And they're stable at room temperature.

The Problem

Why Your Probiotic
Probably Isn't Working

  • Gut Lining Support

    HK L-137 upregulates the expression of tight junction proteins - the molecular 'glue' that holds your gut lining together. A stronger gut lining means fewer toxins entering the bloodstream and better nutrient absorption.
    Pathway 1

  • Immune Modulation

    HK L-137 activates pattern recognition receptors (TLR2) on immune cells, triggering a balanced immune response. This is why it's been shown to reduce the duration of colds and upper respiratory infections.
    Pathway 2

  • Microbiome Balance

    By improving the gut environment, stronger lining, better immune balance - HK L-137 creates the conditions in which beneficial bacteria can thrive. It doesn't add bacteria; it builds the ecosystem they need.
    Pathway 3
