Why We Love It

Delivers live, thriving bacteria.
Offers clinically proven effectiveness.

Main Highlights

📈 MULTIPLIES & COLONISES – Bio–Alive is different. Each probiotic vial (6,000,000,000 CFU) is equivalent of taking a dose of 300,000,000,000 CFU of pills or powder. This ability to deliver thriving bacteria is what makes Bio-Alive so special. Our probiotics are exceptionally effective in smaller doses because our bacteria are alive and multiplying. 98% reach the gut alive; It’s why you can feel the difference!
🧫 BACTERIA THAT'S ALIVE & THRIVING – With Bio-Alive probiotics our smart (prebiotic & postbiotic enriched) liquid complex doesn’t trigger digestion. That means we're able to use energetic and multiplying bacteria. Most probiotics are typically freeze-dried to ensure the bacteria within them survives through the stomach. This means the majority of the bacteria end up lethargic with only 2-3% actually active. With Bio-Alive, ALL our thriving bacteria are able to multiply and deliver transformative results.
🔬 CLINICALLY PROVEN – University College London carried out an independent study on leading formulas containing bacteria. The study subjected each probiotic to three tests. These assessed if the bacteria arrived in a live state, survived stomach acid transit and thrived in the target area of the gut. Liquid-Complex Probiotics like Bio–Alive were the only formulas to pass all three tests and deliver transformative results.
👨‍🔬 FORMULATED BY DR EMANUEL PALECO – He’s the driving force and visionary behind the Institute of Medical Physics. After earning his education in Quantum Nuclear Engineering and mastering in Biology, Nutrition, and Sports Science, he went on to lead research in Genetics and Transdermal Delivery. In a career that has circumnavigated the globe, Dr. Paleco has spent over 30 years revolutionising the industry and training physicians globally.
