Bifidobacterium Infantis in Sodatide: Strain, Dose and Evidence
Bifidobacterium infantis is one of three bacteria in Sodatide's 36 mg probiotic blend, with no CFU count or strain code on the label. Its best-known trial used strain 35624 in 362 women with IBS: only 100 million CFU a day beat placebo on pain and bloating (Whorwell 2006 (B. infantis 35624, IBS)). No study links it to weight loss.

The basics
What is Bifidobacterium infantis?
Bifidobacterium infantis is a probiotic bacterium. Its full scientific name is Bifidobacterium longum subspecies infantis, and labels often shorten it to B. infantis.
Researchers have studied it mostly for gut comfort, such as belly pain and bloating in IBS.
On the Sodatide label it comes first in the probiotic blend, ahead of Clostridium butyricum and Akkermansia muciniphila. Blend ingredients are listed by weight, largest first (21 CFR 101.36 (proprietary blends)), so B. infantis likely makes up the biggest share of the 36 mg. How big, the label does not say.
| Label name | Bifidobacterium infantis (in the 36 mg Probiotic Blend) |
|---|---|
| What it is | Bifidobacterium longum subsp. infantis · Probiotic bacterium |
| Position on the label | 4 of 5 (label order: inulin, resistant starch, then the probiotic blend; the blend lists its three strains without amounts) |
| Amount on the label | Not published (part of the 36 mg blend; no CFU count) |
| What research has used | 100 million CFU a day of strain 35624 for 4 weeks (IBS trial, 362 women) |
| Strength of evidence | IBS symptoms with one strain; no weight data |
| What it is sold for | Studied for bloating and IBS symptoms |
| Main caution | FDA warned that probiotics can cause fatal infections in preterm infants; keep away from babies. |
Dose check
How much B. infantis is in a Sodatide capsule?
The exact amount is not published. The label gives one total weight for three bacteria and no live count. With probiotics, the count is the number that matters, and a weight cannot be turned into one (NIH ODS, Probiotics (health professional)).
| Detail | Sodatide label | IBS trial |
|---|---|---|
| Strain | Not published | 35624 |
| Daily amount | Not published (part of a 36 mg blend) | 100 million CFU |
| Other bacteria in the dose | C. butyricum and Akkermansia | None |
| Fiber in the dose | 311 mg of inulin and resistant starch | None |
| Length of use | 30 capsules per bottle | 4 weeks |
| Who took it | Adults 18+, per the label | Women with IBS |
Every row differs, so the trial cannot vouch for the capsule. That is how strain research works.
The study
What did the B. infantis IBS trial find?
It found that one dose helped and the others did not. In 2006, 362 women with IBS took strain 35624 at one of three doses, or a placebo, for 4 weeks (Whorwell 2006 (B. infantis 35624, IBS)).
| Daily dose | Better than placebo? |
|---|---|
| 1 million CFU | No |
| 100 million CFU | Yes: belly pain, bloating and other symptoms; global relief more than 20% above placebo |
| 10 billion CFU | No |
The surprise is the top dose. More bacteria did not mean more relief. The plain lesson for you: a bigger number on a label is not automatically better, and a smaller one is not automatically weak.
No significant side effects showed up in that trial. It tested one strain, in one form, in women only.
Gut comfort
Does B. infantis help with bloating?
One strain at one dose eased bloating in women with IBS. Whether Sodatide's B. infantis does the same is unknown, because its strain and count are not on the label.
Think of a 37-year-old with IBS who bloats on fiber bars. The bacterium is a fair thing for her to try with her doctor's input. But Sodatide also holds 211 mg of chicory inulin, a fructan, and fructans may bother some sensitive guts. At this small amount it may not matter, but it is worth knowing.
Try one new product at a time for 4 weeks, the length of the trial. Keep a short daily note on pain, bloating and stool. If nothing changes, you have your answer. If symptoms get worse, stop and tell your doctor.
Evidence, ranked
How strong is the evidence behind Sodatide's formula?
- Inulin, in grams20 trials, 607 adults
At gram doses only LDL cholesterol fell overall; glucose showed no clear change. (Liu 2017 (inulin meta-analysis))
- Resistant starch22 trials, 670 people
At 8-66 g a day, judged of limited cardiometabolic benefit. (Snelson 2019 (resistant starch meta-analysis))
- AkkermansiaPilot trial, 32 adults
Insulin sensitivity improved with the pasteurized form; weight change was not significant. (Depommier 2019 (Akkermansia pilot))
- Look-alike formula76 adults with type 2 diabetes
A different 5-strain mix plus inulin, 6 capsules a day: glucose response improved, weight did not change. (Perraudeau 2020 (WBF-011 trial))
- SodatideNo study of the product
No trial of Sodatide itself, and no CFU count to compare with any study. (FTC Health Products Compliance Guidance)
Bar length shows how directly each line of evidence answers the question: will one Sodatide capsule a day help my metabolism or appetite? It is our editorial summary of the linked sources, not a score from any study.
B. infantis has no rung of its own on the ladder, because no study tested it for metabolism or appetite on its own.
The claim
Is B. infantis a weight-loss probiotic?
No study shows that. The IBS trial did not measure weight. The one trial with B. infantis in a metabolic formula, WBF-011, mixed it with four other strains and inulin, at 6 capsules a day, in 76 adults with type 2 diabetes. Glucose response after a meal improved, and body weight did not change (Perraudeau 2020 (WBF-011 trial)). The authors worked for the company that made it.
Sodatide shares three of those five strains, in one capsule, with no counts. So even that trial does not carry over. Across probiotics in general, the newest review found no effect on weight or BMI (NIH ODS, Weight loss supplements).
Safety
Is Bifidobacterium infantis safe?
For most healthy adults, probiotics are unlikely to cause harm (NIH ODS, Probiotics (health professional)). The rare serious risk is infection, and it falls on people who are very ill or have a weak immune system (NCCIH, Probiotics).
In 2023 the FDA warned that probiotics can cause invasive, potentially fatal infection in preterm infants. One death followed sepsis matched to a product containing B. infantis (FDA letter, probiotics in preterm infants). Sodatide is for adults; store the bottle out of children's reach.
Ask a doctor first if you get chemotherapy, take transplant drugs or high-dose steroids, have a central line, or recently had bowel surgery. If you are on antibiotics, they may also kill off live bacteria. Our side effects page covers the signs that need prompt care.
Keep exploring
What else should you check on a B. infantis label?
Look for three things on any B. infantis product: a strain code, a CFU count at best-before, and a storage instruction. Sodatide gives the third one only. Our guide on choosing a probiotic shows how to weigh those gaps.
You can also ask the order desk at +1 (302) 200-3480 whether a strain code or count is on file. Note what they say next to your order ID.
FAQ
B. infantis in Sodatide: questions people ask
How much Bifidobacterium infantis is in Sodatide?
The amount is not published. B. infantis is listed first in a 36 mg probiotic blend shared with two other bacteria, so it is likely the largest share by weight. The label prints no CFU count or strain code, so you cannot compare it with study doses.
What is Bifidobacterium infantis good for?
Its best evidence is for IBS symptoms. In a trial of 362 women, strain 35624 at 100 million CFU a day eased belly pain and bloating better than placebo over 4 weeks. Higher and lower doses did not, and the trial measured no weight effects.
Does B. infantis help you lose weight?
There is no evidence that it does. The IBS trial did not measure weight, and a five-strain formula containing B. infantis left body weight unchanged in adults with type 2 diabetes. A recent review of 19 probiotic trials found no effect on weight or BMI.
Which strain of B. infantis is in Sodatide?
The label does not name one. It lists the species only, with no strain code such as 35624. Because results in one strain do not transfer to another, you can ask the order desk whether a strain is on file before buying.
Is B. infantis safe for babies?
Do not give Sodatide or any adult probiotic to a baby. The FDA warned in 2023 that probiotics can cause fatal infections in preterm infants, and one death involved a B. infantis product. Sodatide is labeled for adults, and the label says to keep it away from children.
Can B. infantis cause bloating or gas?
The IBS trial reported no significant side effects. Some people do feel gassy when they start any probiotic or fiber, and Sodatide also contains inulin. If bloating gets worse or belly pain is severe or ongoing, stop and speak with your doctor.
Should I take B. infantis with antibiotics?
Ask your doctor or pharmacist about timing. Antibiotics may kill off live bacteria in a probiotic. Never stop a prescribed antibiotic to make room for a supplement, and report fever or feeling very unwell while taking a probiotic right away.
