Goli Probiotic+ vs Olly Probiotic + Prebiotic: strains, prebiotic amounts and sugar
Goli Probiotic+ lists Bacillus subtilis DE111 with a postbiotic and 50 mg of prebiotic. Olly lists Bacillus coagulans with 1.5 g of prebiotic blend. Here are both labels.
Both of these gummies combine a spore-forming probiotic with a prebiotic. They use different strains, very different amounts of prebiotic, and different serving sizes. The planned comparison for this slot was with another brand whose label we could not source from the NIH database, so we used Olly’s, which is recorded there.
Where these numbers come from
The Goli column is from the Supplement Facts information on Goli’s own product page, read in October 2026. The Olly column is from the label record for that product in the National Institutes of Health Dietary Supplement Label Database, entered in June 2023. Manufacturers change formulas, so check the bottle in your hand before relying on either column.
Gummy Verdict earns a commission if you buy Goli through our links and nothing from Olly. That is a reason to be careful, so this page compares what is printed on the two labels and does not name a winner. We have not tasted or lab-tested either product.
The two labels, per day at the suggested use
| Goli Probiotic+ | Olly Probiotic + Prebiotic | |
|---|---|---|
| Gummies per day | 3, once daily | 1 |
| Probiotic strain | Bacillus subtilis DE111 | Bacillus coagulans MTCC 5856 |
| Probiotic amount on the label | 10 mg | 33 mg |
| CFU count | Not on the page we read | Not in the label record we read |
| Prebiotic | 50 mg of xylooligosaccharides | 1.5 g blend of FOS, inulin and xylitol |
| Postbiotic | 20 mg of heat-treated Lactobacillus paracasei MCC1849 | None listed |

| Total sugars | 5 g | 1 g |

What is actually different
The strain
Both are spore-forming Bacillus species, which is what makes a probiotic practical in a gummy: spores survive heat, storage and stomach acid. Both labels name the strain, which is the first thing to look for. The strains are different organisms with separate research, and results for one do not transfer to the other. See do probiotic gummies survive.
Milligrams, not CFU
Research on probiotics reports doses in colony forming units. In the sources we read, both products give the probiotic by weight. The two weights cannot be compared with each other, because a milligram of one probiotic ingredient can hold a very different number of live cells from a milligram of another. Check each bottle for a CFU count and whether it is guaranteed through expiration.
The prebiotic amount
This is the largest difference on paper. Olly lists a 1.5 g prebiotic blend. Goli lists 50 mg of xylooligosaccharides, which is one thirtieth of that weight. Studies of prebiotic fibers generally used gram amounts.
Two cautions on Olly’s figure. It is a blend, so the amounts of FOS and inulin are not given separately. And the blend includes xylitol, a sugar alcohol used as a sweetener, which is not usually counted as a prebiotic fiber. The label’s 1 g of dietary fiber suggests the fiber portion is about that. See prebiotic, probiotic or postbiotic on a label.
The postbiotic
Goli includes a heat-treated strain of Lactobacillus paracasei, named with its code. Olly’s label does not list a postbiotic. Research on postbiotics is newer and specific to each preparation.
Sugar and serving size
Goli’s serving is three gummies with 5 g of sugars. Olly’s is one gummy with 1 g. Over a month that difference is about 120 g of sugar.
Which label fits which person
- You want a probiotic, a prebiotic and a postbiotic in one product: Goli’s label lists all three.
- You want the larger prebiotic amount: Olly’s label.
- You are limiting sugar, or want one gummy a day: Olly’s label.
- You are sensitive to sugar alcohols or to inulin and FOS, which cause gas in some people: Goli’s smaller prebiotic amount is less likely to.
- A doctor recommended a specific strain: buy that strain, whichever product has it.
- You avoid gelatin: Goli is set with pectin. Check the Olly ingredient list on the bottle.
What the evidence supports
For healthy adults, the evidence that a daily probiotic improves how digestion feels is limited and strain-specific. Published trials of DE111 in healthy adults reported that it was well tolerated, with digestive measures largely unchanged. The NIH notes that much about probiotics remains unproven. Fiber from food has stronger evidence for gut health than either gummy.
Who should check with a doctor first
People with a weakened immune system or a serious illness should speak to a doctor before taking any probiotic. Pregnant and breastfeeding women should ask their health care provider. Persistent digestive symptoms need a medical assessment, not a supplement.

Common questions
Which probiotic strain does each use?
Goli lists Bacillus subtilis DE111. Olly lists Bacillus coagulans MTCC 5856.
Which has more prebiotic?
Olly lists a 1.5 g blend that includes xylitol. Goli lists 50 mg of xylooligosaccharides.
Which has less sugar?
Olly lists 1 g per day. Goli lists 5 g per three-gummy serving.
Do they state CFU?
Not in the sources we read. Both give the probiotic in milligrams. Check the bottle.
Can I take both?
There is no reason to. One daily probiotic is enough, and combining them adds sugar and prebiotic.
