What is Dr. Tobias Deep Immune Probiotics & Prebiotics, and who is it for?
Deep Immune is a daily dietary supplement sold on drtobias.com in 60, 120 and 180 capsule counts. The seller’s blog says it is “formulated with both probiotics and prebiotics, in one, easy to take, daily capsule.” The sales page describes the capsules as delayed-release and vegetarian. It says the product is shelf stable and requires no refrigeration, which the seller pitches as easy to take “wherever life takes you.”
The seller does not name a specific health problem. The sales page positions Deep Immune for “everyday digestive wellness and microbiome support as part of a healthy daily routine.” The label’s cautions, covered below, name the groups who should speak with a doctor first.
How does the seller say it works, and do probiotic and prebiotic supplements actually work?
The seller’s blog explains that probiotics are live bacteria and that prebiotics are “a type of dietary fiber that helps feed and grow good bacteria in your gut.” The blog says that taking the two together boosts the effectiveness of the probiotic. It describes PreforPro as food for the probiotics, so they can keep colonizing the gut. For how prebiotics and probiotics are said to work together, read our guide to prebiotic-probiotic synergy. These are the seller’s own statements.
Whether probiotic and prebiotic supplements work for you depends on the strains, the dose and what you want the product to do. The seller’s blog makes the strain point itself: “Every probiotic is different because of the variation in bacteria strains.” A study of one strain does not settle what another strain does. The studies behind DE111 are the key check here. The sales page calls DE111 “clinically studied.” Ask the seller for the citations before you decide.
For a wider look at what probiotic trials have tested, our page on probiotics doses used in studies (our research library) sorts the trials by strain, dose and condition.
What is in each capsule?
The Supplement Facts panel sets one serving at 2 vegetable capsules, with 90 servings per container. The table follows the groups the label uses.
| Group (as the label lists it) | Ingredient | Amount per serving |
|---|---|---|
| PreforPro prebiotic | PreforPro, made up of LH01 (Myoviridae), LL5 (Siphoviridae), T4D (Myoviridae) and LL12 (Myoviridae) | 15 milligrams |
| Probiotic bacteria | Probiotic Bacteria (4.4 Billion CFU) in total | 27 milligrams |
| Probiotic strain | DE111 (Bacillus subtilis) | Check the bottle label |
| Probiotic strain | Bacillus coagulans | Check the bottle label |
| Probiotic strain | Lactobacillus acidophilus | Check the bottle label |
| Probiotic strain | Bifidobacterium lactis | Check the bottle label |
| Other ingredients | Delayed-release capsules (hydroxypropyl methylcellulose, pectin, water) | Check the bottle label |
| Other ingredients | Maltodextrin | Check the bottle label |
| Other ingredients | Medium chain triglycerides | Check the bottle label |
The label states that the Daily Value has not been established for these ingredients. The sales page lists 4.4 billion CFU for the probiotic blend, but it also says the formula is about more than the count: “Rather than relying on CFU count alone, the formula combines clinically studied probiotic and prebiotic ingredients.” For what a CFU figure means on a label, read our guide to probiotic cfus.

Who should use it, and who should skip it or ask a clinician first?
The label gives the clearest guidance on who should check first: “Pregnant or nursing mothers, children under 18, and individuals with a known medical condition should consult a physician before using this or any dietary supplement.” If you fit one of those groups, talk with a doctor before you take it. If your immune system is weakened, read our guide to probiotic use in immunocompromised patients first, which covers safety in vulnerable groups.
What are the side effects and safety concerns?
The label’s direct safety instruction is “Do not exceed recommended dose.” It also names an allergen warning. These are the cautions printed on the product page.
| Issue | What the label says | What to do |
|---|---|---|
| Dose | Do not exceed recommended dose | Take 2 capsules a day, as directed |
| Pregnant or nursing mothers | Should consult a physician before using this or any dietary supplement | Ask your doctor before you order |
| Children under 18 | Should consult a physician before using this or any dietary supplement | Ask a doctor first |
| Known medical condition | Should consult a physician before using this or any dietary supplement | Ask your clinician, including about colitis or any condition you have |
| Allergens | Manufactured and packaged in a facility which may also process milk, soy, wheat, egg, peanuts, tree nuts, fish and crustacean shellfish | If you have a food allergy, ask the seller how it handles these allergens |
For what studies have recorded about side effects of probiotics, read our page on probiotics side effects in studies (our research library).
How do you take it, and what is the best time of day?
The sales page gives the directions: “Take 2 capsules daily, preferably with a meal, or as directed by your healthcare professional.” The seller’s blog adds: “For best results, take your supplements alongside some food and always make sure to drink plenty of water to stay hydrated.” Pick the meal you eat most consistently.
How much does it cost, and what is the total commitment?
The sales page shows one sale price, $25.99, above the size options. Check the cart before you choose a size.
| Size | Supply | Price |
|---|---|---|
| 60 capsules | 30-day supply | $25.99 sale price shown; confirm in the cart |
| 120 capsules | 60-day supply | Check the cart before ordering |
| 180 capsules | 90-day supply | Check the cart before ordering |
If $25.99 is the price for the 60-capsule size, that works out to about 87 cents a day at two capsules daily. Check the total at checkout for shipping charges. At checkout, confirm you are placing a one-time order unless you want a recurring one.

Buy from the seller’s own site, through the Product Page, where the sale price and size options appear.
Look-alike listings can copy the name and label.

If anything differs, email support@drtobias.com before you pay.
How does it compare with other options, including doing nothing?
| Option | What it involves | What the guides say |
|---|---|---|
| Deep Immune | One daily routine, 2 capsules with a meal | The seller says it is designed for everyday digestive wellness and microbiome support |
| Fermented foods | Yogurt, kefir, sauerkraut, kimchi, miso, pickles or kombucha | The seller’s blog lists these as probiotic food sources, and says cheese, kefir and some yogurts contain both prebiotics and probiotics |
| Prebiotic fiber foods | Foods such as bananas and asparagus | The seller’s blog says inulin feeds good bacteria; Cleveland Clinic notes high-fiber foods such as beans and broccoli can cause more gas at first |
| Over-the-counter options | Antacids, magnesium supplements, probiotics, psyllium husk or laxatives | Cleveland Clinic lists these as options for treating most causes of bloating at home |
| Walking and eating habits | A walk after meals, eating slowly, chewing with your mouth closed, drinking water | NHS and UCLA Health both list these habits |
| A dietitian | An elimination diet or low-FODMAP diet, guided by a professional | Cleveland Clinic says a dietitian can help you identify your food sensitivities |
| Doing nothing | Waiting to see if it passes | Cleveland Clinic says bloating “usually goes away after a while,” but see a provider if it lasts more than a week |
The do-it-yourself version of a probiotic routine means buying fermented and fiber foods, portioning them and remembering to eat them every day. The capsule is the done-for-you version: one daily routine with the count and strains already set. Whether that suits you is your call.
Bloating questions: signs, causes and quick relief
Many readers searching for probiotics are also dealing with bloating, so here are the short answers. Cleveland Clinic’s bloating guide says bloating “happens to almost everyone” and is usually harmless, though it can disrupt your day.
What are the signs of bloating?
NHS bloating guidance says you may be bloated if your tummy feels full or bigger than usual, you have tummy pain or discomfort, your tummy is rumbling or making noises, or you are farting more than usual. Cleveland Clinic adds frequent burping.
Why am I so bloated in my belly?
Excess gas is the most common cause, according to Cleveland Clinic. Gut bacteria produce gas as they break down carbohydrates. Harvard Health’s bloating tips lists swallowing too much air, certain foods such as beans and cabbage-family vegetables, food intolerances, a slowing digestive system, and conditions such as SIBO and IBS. If bloating lasts more than a week, see your healthcare provider.
Why does my belly look big, like I’m pregnant?
Cleveland Clinic says abdominal bloating can occur during your period, during pregnancy and during perimenopause, because estrogen causes water retention. Recent weight gain around the abdomen is also on its list of causes. If you think you could be pregnant, a clinician can check.
What relieves bloating fast, and is there a five-minute fix?
Harvard Health says there is “no magic way to instantly relieve gas,” so plan on a few options rather than one instant fix. Harvard Health says the most popular over-the-counter option is simethicone, which helps break up gas bubbles. It adds that these products may help with occasional bloating but there is no good evidence any work. The NHS suggests you massage your stomach from right to left to release trapped wind, and UCLA Health says a walk of about 10 minutes or 1,000 steps after eating reduces gas and bloating better than medication.
What drinks help with bloating?
The NHS recommends you drink plenty of water. It also advises you not to drink lots of fizzy drinks, alcohol or caffeine in coffee and tea. Cleveland Clinic lists carbonated drinks among things to cut back on.
When should bloating be checked by a clinician?
See your healthcare provider if bloating lasts more than a week, is very painful, or comes with fever, vomiting, bleeding, weakness or unexplained weight loss, according to Cleveland Clinic. The NHS also says to see a GP if you feel bloated regularly or have bloating with unintentional weight loss.
Questions to ask your clinician
- Is a probiotic with a prebiotic appropriate for my health history, including any condition such as colitis?
- Do any of my medicines or supplements interact with these ingredients?
- Would a dietitian help me find food triggers for my bloating?
- Which of my symptoms should be checked sooner rather than later?
Before you order: a short checklist
- Email support@drtobias.com for the refund and returns terms in writing.
- Confirm the price of the 120- and 180-capsule sizes in the cart.
- Check shipping charges and whether a subscription or recurring order applies.
- Ask the seller for the studies behind DE111 and for the amount of each strain; check the bottle label.
- Read the allergen warning if you have a food allergy.
- Talk with a clinician if you are pregnant or nursing, under 18, or have a known medical condition.
Frequently asked questions
Is it the number one rated probiotic on the market?
Compare the strains, CFU amounts and price, and check how any ranking was made before you decide.
Can I take probiotics if I have colitis?
The label says individuals with a known medical condition should consult a physician before using it. Colitis is a medical condition, so ask your doctor or gastroenterologist before you order.
What should you not mix with probiotics?
If you take any medication, ask a pharmacist or your clinician to check before you add the capsules.
Is there a downside to taking probiotics daily?
The label’s direct limit is “Do not exceed recommended dose,” which means 2 capsules a day.
Who should not take it?
The label names three groups: pregnant or nursing mothers, children under 18, and individuals with a known medical condition. It says these people should consult a physician before using it.
