Physician’s Choice Probiotic: A Buyer’s Guide

What Physician’s Choice probiotic is

Physician’s Choice is a US supplement brand with a line of probiotic capsules and gummies. Its best-known product is the 60 Billion Probiotic, a once-a-day capsule with 10 bacterial strains and a small dose of prebiotic fiber. The line also includes a Women’s Probiotic, a 100 Billion Probiotic and a Bloat + Gas Probiotic.

This guide compares only what the brand publishes on its product pages and Supplement Facts panels (labels checked October 2026), plus the published research on the strains it names. Prices and formulas change, so check the current label before you buy.

Ultimate Gut is published by Ultimate Health Solutions, which sells a yogurt maker, probiotic capsules and an inulin fiber supplement. None of the products reviewed here are ours, and these brands don’t pay us.

One point about the name: “Physician’s Choice” is a brand name. It does not mean doctors prescribe the product or that it was tested in a clinical trial. The brand says its formulas were developed with its own team of doctors, which is a different thing from published evidence.

What’s in the 60 Billion Probiotic

According to the Supplement Facts panel on the brand product page, one capsule holds a 220 mg probiotic blend that the brand says delivers 60 billion CFU (colony-forming units) at expiration, not just at manufacture. It also has a 150 mg prebiotic blend of organic inulin from Jerusalem artichoke and chicory plus organic acacia fiber. The capsule shell is hypromellose and gellan gum, which the brand describes as acid-resistant.

The printed label lists species names only and does not show how much of each strain is in the blend. The product page adds the strain codes, which matter because probiotic research is done on specific strains, not whole species.

Strain (as the brand lists it)AmountHuman research we found on this strain
Lacticaseibacillus paracasei Lpc-37Not listed (part of the 60 billion CFU blend)Two stress trials in healthy adults, with mixed results
Bifidobacterium lactis Bl-04Not listedOne cold-virus challenge trial; no effect on colds
Ligilactobacillus salivarius Ls-33Not listedOne 12-week trial in teens with obesity; no change in inflammation or metabolic markers
Lacticaseibacillus casei Lc-11, Lactobacillus acidophilus La-14, Lactiplantibacillus plantarum Lp-115Not listedWe did not find trials testing these strains alone for bloating or regularity
Bifidobacterium bifidum Bb-06, B. longum Bl-05, B. breve Bb-18, Lactobacillus bulgaricus Lb-87Not listedWe did not find trials testing these strains alone for bloating or regularity

What the research on these strains shows

The strain with the most human data here is Lpc-37. In a 2020 trial of 120 healthy adults, about 17.5 billion CFU a day for five weeks did not meet the study’s main goal, a smaller heart-rate rise during a lab stress test. People taking it did report less perceived stress. A larger 2023 trial gave Lpc-37 or a placebo to 190 university students for 10 weeks before exams and found no effect on stress, mood or anxiety. Both studies were run or funded by the company that makes the strain.

For Bl-04, a randomized trial had 334 healthy volunteers take the strain or a placebo for 28 days before being exposed to a common cold virus. Colds developed in 56% of the Bl-04 group and 50% of the placebo group, which was not a meaningful difference.

For Ls-33, a 12-week trial in 50 teenagers with obesity found no differences in inflammation markers, blood sugar, cholesterol or body measurements compared with placebo.

None of these studies tested the Physician’s Choice capsule itself, and each used one strain at its own dose rather than a 10-strain mix. We did not find a published human trial of the finished 60 Billion Probiotic. Its digestive claims, such as easing occasional bloating and supporting regularity, carry the standard note that the FDA has not evaluated them.

Probiotics as a group do have some solid evidence in one area. A 2019 Cochrane review of 33 trials in children found that probiotics taken with antibiotics cut antibiotic-associated diarrhea from 19% to 8%, rated moderate-certainty evidence. But the NIH Office of Dietary Supplements notes that effects vary by strain, so a group result does not tell you whether a particular blend will help you.

Other Physician’s Choice probiotics

  • Women’s Probiotic: 50 billion CFU from six species (L. plantarum, L. paracasei, L. casei, L. gasseri, L. acidophilus and B. lactis), a prebiotic blend, 60 mg D-mannose and 50 mg cranberry fruit powder (CRANDOR), per its Supplement Facts panel. The label names species, not strains. See our guide to probiotics for women for how strain choice matters here.
  • Bloat + Gas Probiotic: a different kind of product. Its label lists 2 billion CFU of Bacillus subtilis (OPTIBIOME BS50), tributyrin (CoreBiome), acacia fiber, artichoke leaf, ginger root, and the enzymes lactase and alpha-galactosidase. Our tributyrin supplement guide covers that ingredient.
  • 100 Billion Probiotic: the brand describes 100 billion CFU from 16 strains with organic prebiotics in a delayed-release capsule. A higher count does not mean better results; the NIH Office of Dietary Supplements says higher CFU counts alone don’t necessarily mean greater health benefits.

What it costs

One capsule is one serving. In October 2026 the brand page listed the 60 Billion Probiotic at roughly $0.61 to $0.69 per serving on subscription, depending on how many bottles you order. One-time prices are higher, and the brand runs frequent discounts, so the number you see may differ.

How to choose and use a probiotic like this

  • Start with your goal, then find the strain: the research supports specific strains for specific uses. NCCIH notes that a benefit from one kind of Lactobacillus doesn’t mean another will do the same. Look for a strain code that was tested for your concern.
  • Prefer CFU at expiration: counts drop over time, and the NIH Office of Dietary Supplements says some experts favor labels that state the count at the expiration date. Physician’s Choice does this for the 60 Billion Probiotic.
  • Look for a named testing seal: the brand says the product is third-party tested and Non-GMO Project Verified but does not name the testing lab. A seal such as the USP Verified Mark means an outside group checked that the product contains what the label says.
  • Expect some gas from the fiber at first: inulin and acacia are fermentable fibers. Mayo Clinic notes that adding fiber too quickly can cause gas, bloating and cramping.
  • Give it a fair trial, then decide: if nothing changes after several weeks, there is little reason to keep paying. Our article on taking too many probiotics covers stacking products.
  • Consider food first: yogurt and kefir with live cultures are another way to get probiotics. See our comparison of probiotic capsules versus yogurt and our list of probiotic foods.

Keep in mind that dietary supplements are not approved by the FDA before they reach store shelves; the FDA says it has no authority to approve them before they are marketed.

Who should check with a doctor first

Probiotics have a long record of apparently safe use in healthy people, according to NCCIH, though gas is common at first. The risk of harm is greater in people with severe illnesses or weakened immune systems. The NIH Office of Dietary Supplements notes that reported bloodstream infections linked to probiotics mostly involved people who were severely ill, in intensive care, or had a central venous catheter. Premature infants should not be given probiotics without medical advice. If you are pregnant, breastfeeding or take regular medication, ask your clinician before starting.

A probiotic is not a fix for ongoing gut symptoms. See a doctor promptly if you have diarrhea that lasts more than 2 days, a high fever, severe belly or rectal pain, black or bloody stools, frequent vomiting or signs of dehydration, as NIDDK advises.
