Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place.

HelloPharmacist Scorecard of Lactase Enzyme by Reliable-1 Laboratories
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
Low disclosure
This product contains one active ingredient: lactase, an enzyme that breaks down lactose (the sugar in milk and dairy products). Lactase works directly in your digestive system, helping your body process dairy so you can eat and drink it without discomfort.
The remaining ingredients — microcrystalline cellulose, croscarmellose sodium, magnesium stearate, silica, and colloidal silicon dioxide — are inactive ingredients used to form and stabilize the product.
Does it work?
Strong evidence
Lactase is effective for lactose intolerance, meaning it helps people who have trouble digesting lactose digest dairy products. The evidence for its use in prematurity and colic isn't established well enough for us to rate it — the data we hold shows insufficient reliable evidence on both counts.
How safe is it?
Well-documented data
Lactase is generally well tolerated when you use it as directed. The facts note that safety during pregnancy is likely okay, though the data is limited — talk with your doctor before taking it regularly while pregnant.
For breastfeeding, lactase acts only in the gut, so its risk is low — but because the data is sparse, ask your doctor or pharmacist first. A very rare case of allergic skin reaction and allergic rhinoconjunctivitis (allergy of the nose and eyes) has been reported in a laboratory worker exposed to powdered lactase over time; if you've had a previous allergy to lactase, mention it to your pharmacist.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredient we checked. Lactase works only in your digestive tract and doesn't affect how your medications are processed.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
Lactase is a straightforward option if you have trouble digesting dairy products and want an enzyme boost with your meals. It's generally well tolerated and doesn't interact with medications.
If you're pregnant, breastfeeding, or have a history of enzyme allergies, talk it over with your doctor or pharmacist to make sure it's right for you.
