HelloPharmacist Scorecard of Ultra Dairy Support by Vitabase

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 5 active ingredients.
  • “Proprietary Enzyme Blend” is a proprietary blend — the label gives one combined amount (220 mg) without saying how much of each component you get.

Ultra Dairy Support contains 5 active ingredients. Three are digestive enzymes: Lipase helps break down fats, Lactase breaks down the milk sugar lactose, and Proteases (protein-digesting enzymes) work on proteins.

The fourth ingredient is Lactobacillus acidophilus, a beneficial bacteria (probiotic) that supports gut flora. The fifth is Lactobacillus rhamnosus, another probiotic strain.

The capsules also contain inactive ingredients including cellulose and water to hold everything together.

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: Helps digest dairy-containing foods.
  • We looked for evidence on: Lactose intolerance, Dairy digestion, Lactose malabsorption, Post-dairy bloating.
  • The strongest evidence on file: Lactase is rated "Effective" for Lactose intolerance (Natural Medicines).
  • Also on file: Lactobacillus Acidophilus is rated "Insufficient Reliable Evidence To Rate" for Lactose intolerance.

Lactase in this product is rated Effective for lactose intolerance — it's the best-studied ingredient here. Lactobacillus acidophilus is rated Possibly Effective for irritable bowel syndrome (IBS), the digestive tract infection H. pylori, antibiotic-associated diarrhea, and bacterial vaginosis.

For Lipase, Proteases, and Lactobacillus rhamnosus, the evidence in our data either isn't established or is rated Insufficient Reliable Evidence — meaning we don't have enough good research to say whether they work for their intended purposes.

The evidence, ingredient by ingredient Lipase Lactase Proteolytic Enzymes (proteases) Lactobacillus Acidophilus

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Overall, the ingredients are generally well tolerated. Lipase, Lactase, and Proteases don't have major safety red flags in adults, though people with serious digestive conditions should use Lipase only under medical guidance.

Lactobacillus acidophilus is safe in healthy adults and children. Rare allergic reactions to proteases have been reported in occupational settings; if you have a known sensitivity to enzymes, mention it.

Pregnancy and breastfeeding: Lactase is rated Likely Safe in pregnancy. Lipase, Proteases, and Lactobacillus acidophilus have limited safety data — there isn't enough research to know either way, so talk with your doctor before using during pregnancy or while nursing.

We don't hold pregnancy or breastfeeding data for Lactobacillus rhamnosus.

Side effects, ingredient by ingredient Lipase Lactase Proteolytic Enzymes (proteases) Lactobacillus Acidophilus

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 4 matched ingredients can interact with medications — Lactobacillus Acidophilus.
  • The most serious interaction on file is rated Moderate.
  • For scale: 182 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Antibiotic drugs are the main medication type to watch — a Moderate interaction with Lactobacillus acidophilus means they might reduce the probiotic's effectiveness if taken at the same time. Space your antibiotic and this supplement several hours apart.

For Lactobacillus rhamnosus, we couldn't check interactions because we hold no data for it, so mention that ingredient when you talk to your pharmacist.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help if you're dealing with lactose intolerance or digestive discomfort, especially if you're on antibiotics or have IBS — but effectiveness varies by ingredient. The big thing to watch: if you're taking antibiotics, time them away from this probiotic so the medication doesn't kill off the beneficial bacteria.

Check with your pharmacist about your specific medications before starting.

Antibiotic Drugs

Theoretically, taking Lactobacillus acidophilus with antibiotic drugs might decrease the effectiveness of L. acidophilus.
L. acidophilus preparations usually contain live and active organisms. Therefore, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and L. acidophilus preparations by at least two hours.

Ultra Dairy Support by Vitabase: Common Questions

Does Ultra Dairy Support by Vitabase interact with any medications?
Yes. Based on its ingredients, Ultra Dairy Support has a known interaction with 182 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Ultra Dairy Support contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Will this help my lactose intolerance?
Lactase, one of the enzymes in this product, is rated Effective for lactose intolerance — that's the one with the most solid evidence. It breaks down lactose (the milk sugar) so your body can digest it better.
Can I take this while I'm on antibiotics?
You can, but timing matters. Antibiotics can kill the live Lactobacillus acidophilus in this product, making it less effective. Ask your pharmacist how many hours apart to take them — usually spacing them several hours helps.
Is it safe to take while I'm pregnant?
Lactase is rated Likely Safe in pregnancy. The other ingredients — Lipase, Proteases, and the probiotics — don't have enough research to know either way, so check with your doctor or pharmacist before starting, especially if you're using it regularly.
Can I breastfeed while taking this?
Lactase and Lactobacillus acidophilus are considered low-risk while breastfeeding, but the data are limited. Lipase and Proteases have little safety information for nursing — ask your doctor or pharmacist before you start, since they can give you personalized advice.
What does the Proprietary Enzyme Blend contain?
The facts don't break down what's in that blend — it's listed as a proprietary formula, so the exact combination isn't detailed. The other enzymes listed separately (Lipase and Proteases) are your main active enzyme ingredients.
Are there any side effects?
Most people tolerate it well. Rarely, proteases can trigger allergic reactions in sensitive people. The probiotics might cause mild gas, bloating, or stomach upset in some folks, but that's uncommon. No serious adverse effects have been reported in adults in our data.
