Lactase (Digestive Enzyme)
Helps to digest lactose and relieve symptoms of lactose intolerance.
Also known as: Lactase Enzyme
Overview
Lactase is a digestive enzyme that breaks down lactose, the sugar found in milk and dairy products. Individuals with lactose intolerance do not produce enough lactase, leading to digestive symptoms like bloating, gas, and diarrhea after consuming dairy. Lactase supplements provide the enzyme externally, allowing for the proper digestion of lactose and the prevention of these uncomfortable symptoms.
Key Benefits
Prevents Bloating and Gas
By breaking down lactose, lactase prevents it from fermenting in the gut, which is the cause of gas and bloating.
Reduces Diarrhea
Proper lactose digestion prevents the osmotic effect that draws water into the intestines, thus preventing diarrhea.
Allows for Dairy Consumption
Lactase supplements enable individuals with lactose intolerance to enjoy dairy products without discomfort.
Dosage & How to Take
The dosage of lactase is measured in FCC (Food Chemical Codex) units. A typical dose is 3000-9000 FCC units, taken just before the first bite or sip of a dairy-containing meal. The exact dose needed can vary depending on the individual's level of intolerance and the amount of lactose in the meal.
| Purpose | Dose | Notes |
|---|---|---|
| Mild Intolerance | 3000 FCC units | For small amounts of dairy. |
| Moderate to Severe Intolerance | 6000-9000 FCC units | For larger meals containing dairy. |
Best Time to Take
Must be taken immediately before consuming dairy for it to be effective.
With or Without Food
Must be taken with the first bite of food or drink containing lactose.
