A postbiotic is a preparation of inanimate (non-living) microorganisms and/or their components that confers a health benefit on the host. This is the formal definition established by the International Scientific Association for Probiotics and Prebiotics (ISAPP) in 2021. In simple terms, postbiotics are the bioactive compounds that bacteria produce — the finished, active product that delivers the benefit, without needing the bacteria to be alive.

Probiotics are live bacteria. They must survive your stomach acid, travel to your gut, and establish a colony before they can do anything. Studies suggest up to 99% of probiotic bacteria in standard supplements die before reaching the gut. Postbiotics are already in their active form — they don't need to survive, colonise, or grow. They begin working immediately upon absorption.

HK L-137 stands for Heat-Killed Lactiplantibacillus plantarum L-137. It is a specific strain of bacteria that has been heat-treated to render it non-living, then standardised into a consistent, stable postbiotic preparation. It is the most extensively studied postbiotic in existence, with 15+ peer-reviewed clinical trials published over 15 years in journals including the Journal of Nutrition, European Journal of Nutrition, and Frontiers in Medicine.

Yes. The heat-killing process is precisely what makes HK L-137 a postbiotic rather than a probiotic. The heat treatment standardises the bacterial cell wall components — particularly the peptidoglycan and lipoteichoic acid - into a consistent, stable preparation. These cell wall fragments are what interact with your immune receptors and gut lining. The clinical benefits of HK L-137 come from these structural components, not from the bacteria being alive.

Biomewise Postbiotic Gummies are mixed berry flavoured, with a natural sweetness from the pectin-based gummy base. They are not overly sweet and have no artificial aftertaste. Most customers describe them as genuinely enjoyable - one of the reasons the daily habit is so easy to maintain.

No. Unlike many probiotic supplements, Biomewise postbiotic gummies are shelf-stable and do not require refrigeration. Store in a cool, dry place below 25°C, away from direct sunlight. This makes Biomewise ideal for travel, gym bags, desk drawers, and any on-the-go lifestyle.

Biomewise is free from the 14 major allergens: gluten, dairy, soy, eggs, nuts, peanuts, sesame, celery, mustard, lupin, molluscs, fish, crustaceans, and sulphites. The product is manufactured in a GMP-certified facility with allergen controls in place.

Biomewise is formulated for adults aged 18 and over. If you are considering giving any supplement to a child, please consult a paediatrician or GP first.

We recommend consulting your GP or midwife before taking any supplement during pregnancy or breastfeeding.

Most customers notice improved digestion within 1–2 weeks of consistent daily use. Reduced bloating is typically the first benefit reported. By week 4, most customers experience better energy levels, clearer skin, and improved overall wellbeing. Individual results vary - consistent daily use gives the best outcomes.

We offer a 30-day money-back guarantee. If you are not satisfied with your results after 30 days of consistent daily use, contact us at info@biomewise.co for a full refund. No questions asked.

Yes. Biomewise is designed to complement your existing supplement routine. Many customers take it alongside protein powder, creatine, multivitamins, and omega-3s. If you are taking prescription medication, consult your GP before adding any new supplement.

The benefits of postbiotics are maintained through consistent daily use, similar to how the benefits of a healthy diet are maintained through consistent healthy eating. Most customers choose to continue taking Biomewise as part of their daily wellness routine. If you stop, the benefits will gradually reduce over time.

Every Biomewise bottle includes a unique QR code that links to the Certificate of Analysis (COA) for that specific batch. The COA shows the exact test results for active ingredient potency, heavy metals (Lead, Arsenic, total metals), and microbiological safety (E. Coli, Salmonella, Staph aureus). You can verify that the bottle in your hand has passed every safety and quality test.

Every batch of Biomewise is tested by an independent, ISO-accredited third-party laboratory. We do not use in-house testing for our published results. The testing laboratory is independent of our manufacturing facility and has no commercial relationship with Biomewise beyond the testing contract.

Biomewise is manufactured in a GMP (Good Manufacturing Practice) certified facility. The facility is registered with the relevant regulatory authorities and undergoes regular independent audits. Full manufacturing details are available on request.

GMP (Good Manufacturing Practice) is a system for ensuring that products are consistently produced and controlled according to quality standards. GMP certification means the manufacturing facility has been independently audited and verified to meet strict standards for hygiene, equipment calibration, ingredient traceability, and quality control

Active ingredient potency is verified in every batch by our independent testing laboratory. The Certificate of Analysis for each batch - accessible via the QR code on your bottle - includes the verified potency results for all active ingredients. This is the only way to truly verify that what's on the label is what's in the bottle.
