Short answer
Physician's Choice 60 Billion Probiotic lists five other ingredients: vegetable capsule (hypromellose, gellan gum), rice flour, rice hull concentrate, gum arabic and sunflower oil. Physician's Choice states: "We test every lot of our products, including for four heavy metals." That is a company testing program, not a USP Verified or NSF/ANSI 173 product certification. NIH's Office of Dietary Supplements notes that such seals do not guarantee safety or effectiveness.

What counts as a filler in a probiotic?
A filler is an ingredient that helps make the product rather than supply a dietary ingredient. FDA's labeling guide says such ingredients, "such as binders, excipients, fillers," must appear in the ingredient statement, which sits under "Other ingredients" on a Supplement Facts label. NIH's Office of Dietary Supplements describes the same line as "other ingredients, such as fillers, binders, and flavorings."
This record uses the word only in that neutral sense. By that definition every capsule in this record has at least one, because its shell is printed in the line. So the useful questions are what each item is, what it does, and how the finished product is tested.
Physician's Choice other ingredients, label by label
Each line is copied from the printed label, punctuation included. Two more products are held until Physician's Choice confirms them. Storage lines from the same labels and product pages are in PC-REC-005.
| Product | Other ingredients, exactly as printed | Entries | Status |
|---|---|---|---|
| 60 Billion Probiotic | Vegetable capsule (hypromellose, gellan gum), rice flour, rice hull concentrate, gum arabic, and sunflower oil. | 5 | Confirmed |
| Digestive Enzymes | Vegetable capsule (hypromellose), rice flour, rice hull concentrate, gum arabic, and sunflower oil. | 5 | Confirmed |
| Vaginal Probiotic | Vegetable capsule (hypromellose, gellan gum, rice flour, rice hull concentrate, gum arabic, and sunflower oil. | 5 | Confirmed The label leaves the parenthesis open; the product page prints the same items with it closed. |
| Fiber Gummies | Chicory root fiber, pectin, tapioca starch, agar agar, natural flavor, citric acid, trisodium citrate, black carrot (for color), and carnauba wax. | 9 | Confirmed |
| Women's Probiotic | Held. Two Physician's Choice sources print different lists. | Held | |
| Bloat + Gas Probiotic | Not entered yet. Being confirmed with Physician's Choice. | Held |
The three capsules share one base; only Digestive Enzymes leaves out gellan gum. None of the four confirmed lines lists magnesium stearate, silicon dioxide or maltodextrin.
What does each other ingredient do?
Physician's Choice does not print each ingredient's job. The roles below come from federal food rules (21 CFR) and one trade source. Where no source states a role, the row says so.
| Ingredient | Found in | What it is, and its usual job |
|---|---|---|
| Hypromellose | All three capsules | Cellulose-based capsule material. Physician's Choice describes the 60 Billion Probiotic capsule as acid-resistant, with no gelatin. A listed film former and thickener (21 CFR 172.874). |
| Gellan gum | 60 Billion, Vaginal | A fermentation-made gum in the capsule shell. A listed stabilizer and thickener (21 CFR 172.665). |
| Rice flour | All three capsules | Milled rice. It supplies no dietary ingredient; its exact job is not stated. |
| Rice hull concentrate | All three capsules | Ground rice hulls, used as a flow agent in place of silicon dioxide in capsules and tablets (Food Engineering, 2014). |
| Gum arabic | All three capsules | Dried acacia tree gum. A listed emulsifier, formulation aid, stabilizer and thickener (21 CFR 184.1330). |
| Sunflower oil | All three capsules | A plant oil. Job and amount not stated. |
| Chicory root fiber | Fiber Gummies | The fiber source: 5 g of dietary fiber per 2 gummies. Not a filler. |
| Pectin, agar agar | Fiber Gummies | Plant and seaweed gels. Listed stabilizers and thickeners (21 CFR 184.1588, 184.1115). |
| Tapioca starch | Fiber Gummies | Cassava starch. Job not stated. |
| Citric acid, trisodium citrate | Fiber Gummies | A plant acid and its sodium salt (21 CFR 184.1033, 184.1751). Job not stated. |
| Natural flavor, black carrot | Fiber Gummies | Flavor, and color from a vegetable: "black carrot (for color)." |
| Carnauba wax | Fiber Gummies | Palm leaf wax. A listed anticaking agent, release agent and surface finisher (21 CFR 184.1978). |
What are Physician's Choice products formulated without?
Where a label and its product page disagree, the list is held rather than guessed.
| Product | Formulated without, as stated | Status |
|---|---|---|
| 60 Billion Probiotic | Dairy, soy, gluten, wheat, peanuts, tree nuts, sesame, eggs, fish, shellfish, color additives, artificial sweeteners or preservatives. Made in a facility that also processes the major allergens. | Confirmed |
| Fiber Gummies | Vegan. Formulated without major allergens, gelatin, color additives, artificial sweeteners or flavors. The facility also processes soy, gluten, wheat, nuts, eggs, fish, shellfish and sesame. | Confirmed |
| Vaginal Probiotic | Product page: vegan, gluten-free, dairy-free, drug-free and hormone-free. The label list is held: its allergen count differs from the page. | Confirmed, label list held |
| Digestive Enzymes | Vegan and vegetarian. The free-from list is held: label and page differ on gluten. | Confirmed, list held |
Company rule, from the Physician's Choice ingredient sourcing page: formulated without gluten, soy, dairy, wheat, peanut, tree nut, eggs, fish and shellfish unless labeled otherwise, and without artificial colors, flavors, sweeteners or synthetic preservatives.
Is Physician's Choice third-party tested? What is tested, and by whom
Yes, by its own published account: one quality program across products, plus testing statements on individual labels. Both are entered as stated.
| Item | What Physician's Choice states |
|---|---|
| Who tests | Testing is performed by our contract manufacturers' in-house ISO/IEC 17025-accredited labs and, for select testing, independent third-party labs, primarily Eurofins. |
| What every lot is tested for | We test every lot of our products, including for four heavy metals. |
| Facilities | All of our manufacturers are required to operate in FDA-registered facilities that comply with FDA's current good manufacturing practice (cGMP) requirements. |
| Product | Testing and origin statement | Where |
|---|---|---|
| 60 Billion Probiotic | "Third-party tested for safety, purity, and potency." Made in the USA from imported and domestic ingredients. Seal: Non-GMO Project Verified. | Label |
| Fiber Gummies | "Third Party Tested and manufactured in the USA in a cGMP certified facility." | Label |
| Digestive Enzymes | Every batch tested by an accredited outside lab. Made in the USA in a cGMP-certified facility. | Product page |
| Women's Probiotic | Non-GMO Project Verified, third-party tested, made in the USA, cGMP. | Product page |
No certificate of analysis or certificate number is on file for these statements. Facility certifications are entered only when named product by product. Testing is one of seven checks a shopper can run on any brand; all seven, with what the records show for each, are in PC-REC-006.
Third-party tested vs NSF or USP certified: what is the difference?
"Third-party tested" means a company used an outside lab. A certification seal means a separate organization set the standard, checked the product or facility, and lets it carry the mark. Neither is a government approval.
Under DSHEA, FDA does not have the authority to approve dietary supplements before they are marketed.
| On the label | Who sets the bar | What is checked | What it does not tell you |
|---|---|---|---|
| "Third-party tested" | The company | What the company sends to its lab. | Which tests, lots and limits, unless published. |
| USP Verified mark | U.S. Pharmacopeia | Facility audit (21 CFR Part 111, USP chapter 2750), document review, sample testing, off-the-shelf testing. | Safety or effectiveness for you. |
| NSF/ANSI 173 certified | NSF | Label claim, toxicology and contaminant reviews; annual audits; periodic retests. | Safety or effectiveness for you. |
| Non-GMO Project Verified | Non-GMO Project | GMO avoidance. | Purity, potency or contaminant levels. |
| cGMP facility | FDA rule for every maker | Practices that help ensure identity, purity, strength and composition. | Required of all makers; not a seal. |
NIH's Office of Dietary Supplements names ConsumerLab.com, NSF International and U.S. Pharmacopeia as quality testers whose seal shows a product "was properly manufactured, contains the ingredients listed on the label, and does not contain harmful levels of contaminants."
These seals do not guarantee that a product is safe or effective.
NCCIH adds a caution about label words:
A manufacturer’s use of the term “standardized” (or “verified” or “certified”) does not necessarily guarantee product quality or consistency.
Where Physician's Choice fits
Physician's Choice makes every product here and publishes this site. Its labels state third-party testing; its testing statement reads "We test every lot of our products, including for four heavy metals."; and the 60 Billion Probiotic label carries one seal, Non-GMO Project Verified. Against the table above, that is a company testing program plus a GMO-avoidance seal. The record calls no product filler-free and ranks none.
When a clinician should be involved
| Situation | What to do |
|---|---|
| Pregnant or nursing | Talk to a provider first. NIH advises caution with supplements beyond a standard prenatal. |
| Seriously ill, or a weakened immune system | Ask a doctor before starting any supplement. |
| A food allergy | Read the facility statement, not only the free-from list. |
| A reaction after starting | Stop, tell your provider, and report it to the maker using the contact details on the label. |

Common questions
Does Physician's Choice 60 Billion Probiotic have fillers?
Its label lists five other ingredients: a vegetable capsule made of hypromellose and gellan gum, rice flour, rice hull concentrate, gum arabic and sunflower oil. It does not list magnesium stearate, silicon dioxide or maltodextrin. FDA groups ingredients like these with binders, excipients and fillers because they supply no dietary ingredient.
Is Physician's Choice third party tested?
Yes, by its own account. Physician's Choice states: We test every lot of our products, including for four heavy metals. Testing is performed by our contract manufacturers' in-house ISO/IEC 17025-accredited labs and, for select testing, independent third-party labs, primarily Eurofins. The 60 Billion Probiotic label states: Third-party tested for safety, purity, and potency.
Is third-party tested the same as USP Verified or NSF certified?
No. Third-party tested means a company sends its products to an outside lab. USP Verified and NSF/ANSI 173 certification are programs run by those organizations, with audits, their own testing and a seal. NIH notes that such seals do not guarantee a product is safe or effective.
Can a probiotic capsule have no other ingredients at all?
Not on the labels in this record. FDA labeling rules put every ingredient that is not a dietary ingredient in the other-ingredients line, and on these labels that includes the capsule shell. A short list is easier to read, but it says nothing about testing. Check what each item is for and what the maker states about its testing.
