Free 'I Love Bacteria' T-shirt

Culturelle Probiotics is giving away T-shirts with "I (heart) bacteria" on the front by filling out an online form.

And what is a probiotic, you might ask?

The company's Web site has plenty of information on what they are, including that a Culturelle capsule each day helps support good digestion, regularity, enhances the immune system and helps to return you to optimal health.

Our bodies are filled with billions of bacteria, and some are good and some are bad. If too many bad bacteria take over, they can compromise digestion and your immune system. Probiotics can help restore balance.
