What is AAD?

AAD stands for antibiotic-associated diarrhea. Symptoms include bloating, gas and abdominal pain. Common consequences include, running to the bathroom at inappropriate times, increased absenteeism and missing out on important events.

This condition affects up to 35% of patients taking antibiotics and can last for up to two months after the treatment. Almost all antibiotics can cause diarrhea, but the risk is higher with aminopenicillins, cephalosporins, and clindamycin.

How it works

Antibiotics kill harmful bacteria, but they also kill those that help keep you well.

Antibiotic-associated diarrhea (AAD) is a direct consequence of the killing of good bacteria and the most common side effect of antibiotic use.

When beneficial bacteria are eradicated as a consequence of antibiotic use, pathogens have the opportunity to multiply and even cause infections.

Bio-K+ Antibio Pro steps in for their protective action to help prevent AAD and even life-threatening infections like C. difficile.

Targeted release capsules

This technology ensures bacteria pass through the stomach safely, delivering maximum benefits to the intestines—where it counts.

Once ingested, the capsule travels safely through the stomach.

2. RELEASE

Bacteria are released from the capsule once it reaches the intestines, the main site of action.

3. THRIVE

Bacteria are reactivated and ready to reach their full potential throughout the digestive tract.
