HelloPharmacist Scorecard of Delayed Release L. Acidophilus by Nature's Sunshine

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 1 active ingredient.

This product contains one active ingredient: Lactobacillus acidophilus, a live probiotic strain that's meant to support healthy gut bacteria. It's delivered in a delayed-release capsule, which helps the organisms survive stomach acid so they reach your intestines intact.

The capsule also holds some inactive ingredients — hypromellose, water, cellulose, and magnesium stearate — that serve as the capsule shell and a small amount of lubricant.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: friendly bacteria for intestinal tract health.
  • We looked for evidence on: Antibiotic-associated diarrhea, Bacterial vaginosis, Clostridioides difficile infection, Colic, Constipation, Irritable bowel syndrome (IBS) — and 4 related terms.
  • The strongest evidence on file: Lactobacillus Acidophilus is rated "Possibly Effective" for Antibiotic-associated diarrhea (Natural Medicines).
  • Also on file: Lactobacillus Acidophilus is rated "Possibly Effective" for Bacterial vaginosis, Irritable bowel syndrome (IBS).
  • Also on file: Lactobacillus Acidophilus is rated "Insufficient Reliable Evidence To Rate" for Constipation, Lactose intolerance, Necrotizing enterocolitis (NEC), Postoperative infection.

The data shows Lactobacillus acidophilus is possibly effective for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. For atopic disease (allergic conditions), the evidence suggests it's possibly ineffective.

For acute respiratory distress syndrome, there isn't enough reliable evidence to say either way. The strength of evidence varies, so results aren't guaranteed across all these conditions.

The evidence, ingredient by ingredient 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 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.

Lactobacillus acidophilus is generally well tolerated in healthy adults and children. That said, the data are limited in some areas, so check with your doctor before use.

Because it's a live organism, there's a theoretical concern that in rare cases it might cause infection in certain patients — cases of bacteremia, sepsis, and other serious infections have been documented, though most appear linked to bacteria moving from other parts of the body where they naturally live. When taken by mouth, especially combined with other probiotics, some people report mild gastrointestinal side effects like stomach discomfort, bloating, gas, or diarrhea, but these are uncommon.

There is no pregnancy or lactation safety data on file for this ingredient.

Side effects, ingredient by ingredient 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 1 matched ingredient 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 — taking them at the same time as this probiotic may reduce how well L. acidophilus works, so space out your doses and ask your pharmacist for timing guidance. Use the search tool on this page to check your specific medications before you start.

The bottom line

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

This probiotic may be worth considering if you have IBS, antibiotic-associated diarrhea, or certain bacterial infections — the evidence is modest but promising. If you're on antibiotics, time your doses carefully and talk to your pharmacist.

Anyone with a weakened immune system or serious underlying health condition should check with their doctor first.

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.

Delayed Release L. Acidophilus by Nature's Sunshine: Common Questions

Does Delayed Release L. Acidophilus by Nature's Sunshine interact with any medications?
Yes. Based on its ingredients, Delayed Release L. Acidophilus 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?
Delayed Release L. Acidophilus 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.
Will this work if I'm taking an antibiotic?
Not if you take them at the same time. Antibiotics kill the live organisms in this probiotic, so you need to space them out. Ask your pharmacist how many hours to leave between doses — this is really important for the probiotic to work.
What are the common side effects?
Most people tolerate this well. Rarely, people report mild stomach discomfort, bloating, gas, or diarrhea when they start — these are uncommon and usually temporary. If they don't settle down, talk to your pharmacist.
Is it safe for kids?
The data show it's generally well tolerated in children, but the evidence is limited. Talk with your child's doctor before you give it to them.
Can I take this while pregnant or breastfeeding?
There isn't enough safety data on file for this ingredient in pregnancy or lactation. Talk with your doctor or pharmacist for personalized advice.
How does delayed release help?
The delayed-release capsule protects the live organisms from stomach acid so they can reach your intestines, where they're meant to work. Regular capsules would break down too early.
