Can lactose-free foods -- like like lactose-free milk -- and lactase enzyme supplements really help people with lactose intolerance? They may -- but it depends on how much enzyme activity is in the supplement and how much lactose has been removed from the food.
 
ConsumerLab.com selected and tested ten different lactase supplements and three popular brands of lactose-free milk. The testing showed one lactase supplement with so little activity as to be of questionable value. But ConsumerLab.com also found many supplements that met their claims and may be helpful. The three lactose-free milks had no detectable lactose but only two provided a significant amount of vitamin D.
 
ConsumerLab.com found that an equal amount of lactase enzyme (enough to help with a high lactose meal) cost as little as 8 cents to as much as $6.79 depending on the brand of lactase supplement.
 
In this comprehensive review of lactase supplements and lactose-free milks, you'll get test results and quality ratings for 13 lactase supplements and 3 lactose-free milks, as well as information about one other lactase supplement similar to another that was tested. You'll learn:
  • Which lactase supplements (including lactase drops) and lactose-free milks passed or failed testing 
  • How lactase supplements and lactose-free milks compare on quality, ingredients, and cost, and which best save you money
  • The dose of lactase needed to reduce symptoms of lactose intolerance and how to properly take lactase supplements
  • What to expect with lactose-free milk vs. regular milk
  • Strategies and lactose-free food choices to reduce lactose in your diet and treat lactose intolerance
  • What to consider when treating lactose intolerance and potential side-effects of lactase
