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.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.

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
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: lactose digestion support.
  • We looked for evidence on: Lactose intolerance, lactose malabsorption, dairy-induced bloating, dairy-induced diarrhea.
  • The strongest evidence on file: Lactase is rated "Effective" for Lactose intolerance (Natural Medicines).

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.

The evidence, ingredient by ingredient Lactase

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

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.

Side effects, ingredient by ingredient Lactase

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

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.

Does Lactase Enzyme by Reliable-1 Laboratories interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Lactase Enzyme. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Lactase Enzyme contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does lactase actually work for lactose intolerance?
Yes — lactase is effective for lactose intolerance. It's an enzyme that breaks down lactose, the sugar in milk and dairy, so your body can digest it more easily.
Can I take this while I'm pregnant?
The safety data suggests it's likely okay during pregnancy, but the information is limited. Talk with your doctor before taking it regularly while pregnant — they can give you personalized advice based on your health.
Is lactase safe to use while breastfeeding?
Lactase acts only in the gut, so the risk is low. However, the data is sparse — ask your doctor or pharmacist first to confirm it's right for you.
Could lactase help my baby's colic?
There isn't enough reliable evidence yet to say whether lactase helps with colic. If you're thinking about giving it to your infant, talk with your pediatrician first.
What are the side effects?
Lactase is generally well tolerated. A very rare case of allergic skin reaction and nasal/eye allergy has been reported in a worker exposed to powdered lactase over time — mention any previous enzyme allergy to your pharmacist.
