Lactose Intolerance

Nutrients connected to Lactose Intolerance

A link means the body needs the nutrient for this, or that low intake is linked to it. It does not mean extra supplements help if your intake is already adequate; each link shows how strong the evidence is.

• Digestive enzyme supplementsPreliminary or mixed

  NIDDK says lactase tablets or drops can help some people manage symptoms; the NHS says a lactase supplement may reduce or prevent symptoms for some people. Lactase does not raise the body's own lactase, and children and pregnant or breastfeeding women should check with a doctor first.

• Cow's MilkDocumented risk

  Milk contains lactose and can cause belly pain, bloating, gas and diarrhea in lactose-intolerant people.

• YogurtClinically supported

  Yogurt is often better tolerated than milk by people with lactose maldigestion. NIDDK lists yogurt among easier dairy foods.

• Aged CheesePreliminary or mixed

  NIDDK says hard cheeses such as cheddar and Swiss contain less lactose than other dairy foods and are easier to tolerate.

• Cultured ButtermilkDocumented risk

  Buttermilk contains milk sugar; amounts tolerated differ by person.

• Skyr & QuarkDocumented risk

  Lactose amounts vary with how the product is made; tolerance differs by person.

• Lassi & AyranDocumented risk

  Yogurt is easier to tolerate than milk for many people; lassi and ayran were not tested, so tolerance differs.

• Whey Protein PowderDocumented risk

  Concentrate keeps some lactose. Many people with lactose intolerance tolerate some lactose, and the amount differs between people.

• CalciumDeficiency link

  People with lactose intolerance are often at higher risk of low calcium intake.

• KefirPreliminary or mixed

  Kefir improved lactose digestion in one small trial of 15 adults.
