HelloPharmacist Scorecard of Lactase Enzyme 250 mg by KAL
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
KAL Lactase Enzyme 250 mg is a single-ingredient supplement containing lactase, the enzyme that breaks down milk sugar (lactose). The rest of the capsule is made up of inactive ingredients: gelatin, sunflower seed oil, glycerin, lecithin, titanium dioxide, and sorbitol — common fillers and capsule materials.
Does it work?
Strong evidence
Lactase is effective for lactose intolerance — it helps your body digest dairy when your own lactase production is low or absent. For other uses like prematurity or colic in infants, the evidence isn't established enough in our data to rate it one way or the other.
How safe is it?
Well-documented data
Lactase is generally well tolerated when you use it as directed. A rare case of allergic contact dermatitis and nasal allergies has been reported in someone exposed to powdered lactase at work, so if you know you're allergic to lactase itself, this product isn't for you.
In pregnancy and breastfeeding, the safety data suggests it's likely safe, though the research is limited — because it works only in your gut and doesn't enter your bloodstream in significant amounts, talk with your doctor or pharmacist first if you want to use it regularly while pregnant or nursing.
Meds to double-check
No known interactions
No interactions are documented in our data for the medications we could check.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.
This is a straightforward choice for anyone whose body doesn't break down lactose well — it's an enzyme that does the work your digestive system can't. Because lactase stays in your gut and doesn't interact with medications in our data, it's generally a low-risk option.
If you're pregnant, nursing, or have any concerns about allergies, a quick word with your pharmacist or doctor is worth it.
