What is the recommended dosage for Lactase?

General: 3,000-9,000 FCC lactase units per dairy serving; Severe Intolerance: 9,000-12,000 FCC units per dairy serving; Moderate Intolerance: 6,000-9,000 FCC units immediately before dairy consumption

What are the side effects of Lactase?

Potential side effects include: Generally very well-tolerated with minimal side effects, Rare allergic reactions to fungal-derived enzyme (Aspergillus source), Mild abdominal discomfort in rare cases.

What is lactase and how does it work for gut health?

Lactase is a digestive enzyme that breaks down lactose, the sugar found in milk and dairy products, into glucose and galactose for absorption. People with lactose intolerance produce insufficient lactase naturally, leading to bloating, gas, cramping, and diarrhea when consuming dairy. Supplemental lactase taken with dairy-containing meals may help prevent these symptoms by providing the enzyme the body lacks.

What is the recommended dosage of lactase?

Lactase supplements are typically dosed at 3,000-9,000 FCC (Food Chemical Codex) units per serving, taken with the first bite or sip of dairy. The required dose depends on the amount of lactose consumed and individual sensitivity levels. Some individuals may need to take additional doses with larger dairy servings or extended meals.

Are there side effects or interactions with lactase?

Lactase supplements are considered very safe with no significant side effects or drug interactions. They work locally in the digestive tract and are not systemically absorbed. Individuals with galactosemia should avoid lactase supplements, as the enzyme produces galactose from lactose breakdown. Lactase does not address dairy allergies, which involve immune responses to milk proteins rather than lactose sugar.

About

Lactase is a beta-galactosidase enzyme that breaks down lactose (milk sugar) into glucose and galactose in the small intestine. For individuals with lactase deficiency, taking supplemental lactase before consuming dairy may help prevent undigested lactose from reaching the colon, where bacterial fermentation causes gas, bloating, and diarrhea. Research suggests exogenous lactase may reduce lactose intolerance symptoms by 70-80%.

How It Works

Beta-galactosidase enzyme that hydrolyzes lactose disaccharide into glucose and galactose monosaccharides in the small intestine, preventing undigested lactose from reaching the colon where bacterial fermentation produces gas (H2, CO2, CH4) and causes osmotic diarrhea.
