When we get an overall look at the Dr. Tobias Deep Immune Probiotics, you will find that it is a great product. There are a few very nice things about it, such as the fact that you don’t have to refrigerate the capsules, and the fact that the capsules themselves are acid-resistant. What this means is that your stomach acid won’t kill the bacteria before they do what they’re supposed to do in your body. Also, aside from the few people who didn’t notice any effect, the overall opinion is that it’s a great product which will help you with quite a few issues. The product consists of 4 bacteriophages, namely LH01 – Myoviridae, LL12 – Myoviridae, T4D – Myoviridae and LL5 – Siphoviridae. A potential downside is that the product is only for adults, rated at 18+, and it doesn’t do any good for the kids. It is also worth mentioning that you might experience side effects when using the product, such as stomach pain or bloating.

Ingredients Profile:

You will find that Dr. Tobias Deep Immune Probiotics comes with 4.4 billion CFU, in 4 different probiotic strains:

  • Bacillus Subtilis (DE111)
  • Bacillus coagulans
  • Lactobacillus acidophilus
  • Bifidobaecterium lactis

They all have their own uses, but for the purpose of this review I will focus on three of them, namely DE111, Lactobacillus Acidophilus, Bacillus Coagulans. DE111 is a clinically-tested spore forming strain, which supports the proliferation of beneficial bacteria and persist in the GI tract. Lactobacillus Acidophilus is a very useful strain. It has been tried and tested over and over again and you will find that it’s commonly used in a number of probiotic supplements. It has also been quite extensively researched, and studies have shown that it helps IBS symptoms, for example gas, bloating, diarrhea or abdominal pain. However, the other strain I’d like to talk about, Bacillus Coagulans, isn’t all that good. Even though it tends to help with traveler’s diarrhea, and it might even boost the immune function, you will see that it can create spores in the body, which could cause side effects for many people.

The product also has the PreForPro prebiotic, which feeds only the good bacteria in your body, unlike some others such as FOS, which also feed some of the bad bacteria. This is somewhat counterproductive and not very useful for your body. You won’t get that with this product though, and you don’t have to worry about it.

Allergy Concerns:

One more thing about product is that it doesn’t explicitly say whether it has any allergy concerns. If you don’t have any severe allergies, this shouldn’t be a problem for you, but if you do, you might want to think twice. What you should know, however, is that the product states that it is being manufactured in a place that might also be processing egg, peanuts, fish, crustacean shellfish, tree nuts, soy, wheat and milk. As far as I’m concerned, if you have reactions to any of these products, proceed with caution. There are also a few other ingredients, such as vegetable cellulose, medium chain triglycerides and maltodextrin. But, as mentioned above, if you don’t have any problems with allergies, you’ll be fine.


Dr. Tobias Deep Immune Optimum Probiotics comes at $22.48 currently, for a bottle of 60 pills. Considering that you need two pills per day, unlike some other products that only require one per day, the total cost comes out at $0.74 on a daily basis. This is a little on the expensive side, and above the average for a daily probiotic. However, the benefits justify the (little) higher price, so it is worth getting it anyways.


Side Effects:

Even though side effects are usually reserved for really potent products, as well as some which have allergy concerns, there are actually a few side effects with the Dr. Tobias Deep Immune Probiotics. The fact that the product is only 4.4 billion CFU means that the side effects are most probably from the added ingredients or any potential allergens which aren’t mentioned, so again, if you don’t have problems with allergies, you should be good.
