As someone who developed lactose intolerane during early adulthood, I did not want to have to take a pill before every meal with dairy products involved - that just seemed very inconvenient to me.
I found Digestive Advantage Lactose Defense Formula while looking for information about lactose intolerance online. They offered a free sample on their website, and I was amazed at how well the product works!
You take one capsule once daily (the packaging states some people may need to start with 2 capsules daily for up to 2 weeks to get the desierd effects) - I take mine in the morning when I first get up. It allows you to eat as much dairly as you want all day with no stomach discomfort or any other side affects. I have found that it is best to allow at least 30 minutes between taking Lactose Intolerance Therapy and having any dairy - it will still work all day, but needs some time to process before your body will handle daily without any problems.
This product has been a life saver - no longer do I have to avoid ice cream, milk, or cheese pizza, I just take one very small caplet in the morning, and enjoy any food I want!
