Optibac’s For Those on Antibiotics brings together three carefully selected live cultures—Lactobacillus rhamnosus Rosell-11, Bifidobacterium lactis Lafti B94, and Lactobacillus acidophilus/helveticus Rosell-52. These strains have been studied for their ability to reach the gut alive, even when taken alongside antibiotics. Each capsule provides 4.5 billion live cultures, making it simple to add to your daily routine—no fridge required.

At healf, every product is handpicked through our three-step process: Discovery, Expert Validation, and Community Testing. So you can feel confident in your choice.

Optibac specialises in strain-specific probiotics, each formula meticulously crafted with clinically backed, targeted bacterial strains. Their products address a range of health concerns, from gut permeability and immune modulation to hormone regulation and mental wellbeing via the gut-brain axis. Unlike broad-spectrum blends, Optibac focuses on precise combinations, validated by research and stability-tested for effectiveness through digestion. This approach ensures that every supplement offers deep, scientifically rigorous care for your microbiome, supporting optimal health from the inside out.
