About the Company

Onnit is a premium U.S. company that focuses on creating general health and wellness supplements. They soared to fame after their Onnit Alpha Brain nootropic became a success. Since then, Onnit has gone on a mission to create more products that deliver great results to their users. Their Total Gut Health is a relatively new formula, and we’re eager to see what it offers.


Onnit Total Gut Health is a type of supplement that supports your digestion and gut health. But it goes even beyond that.

Since your gut and your brain are very closely linked via the vagus nerve. Onnit Total Gut Health also promotes mental wellness.

As Harvard Medical School put it: “The brain has a direct effect on the stomach and intestines. Patients who tried psychologically based approaches had greater improvement in their digestive symptoms compared with patients who received only conventional medical treatment.” (1)

Here are official claims for Onnit Total Gut Health:

  • Helps break down food & absorb nutrients
  • Aids in immune system support
  • Helps promote healthy gut flora
  • Assists with the digestion of major macronutrients
  • Why a Healthy Diet Alone May Not Be Enough

    You might wonder, why would you need a supplement for these benefits? Isn’t a healthy diet alone enough?

    It definitely is, but how many of us are able to maintain a healthy diet every day? Life gets in the way, you sometimes travel, and it’s hard to stay on top of your meal plan all the time.

    Plus, even if you eat super healthy all the time, you might not get the most out of this food if your digestion is struggling. This is where a quality supplement like Onnit Total Gut Health can really help. By promoting absorption of nutrients along with colonizing your gut with good bacteria.

    Of course, all of this sounds great. But we’re a little skeptical whenever we get our hands on a new product. So, let’s dive into the ingredient formula to see what benefits Onnit Total Gut Health really offers.


    Onnit Total Gut Health contains 15 packets. Each packet has 7 capsules. This will have you covered for 15-20 days.

    But you may wonder, what’s inside these capsules? They contain many ingredients separated into dedicated blends.

    See for yourself:

    DigesTech Power Blend is all about improving your digestion and nutrient absorption. It contains enzymes such as amylase which breaks down carbohydrates. Along with lipase which your body uses to break down and absorb fats.

    Ginger is also added for enhanced digestion. If you have nausea, ginger can help. People who’ll notice the most benefits from this blend are those that have bloating problems. These ingredients should help to prevent, or at least reduce that. (2)

    Betaine HCl

    You’ll get only one capsule containing Betaine HCl per serving. The dosage is 500mg of Betaine Hydrochloride. What Betaine does is increases your stomach acid which helps you break down foods. (4)

    However, it’s worth noting that this is the only ingredient in Onnit Total Gut Health that’s made in a lab. The other ingredients are all earth-growth.

    Probiotic Blend

    Probiotic blend comes with 1 capsule per serving.

    This blend brings more good bacteria to your gut. It brings together friendly live microorganisms to restore harmony in your gut microflora. By taking this blend, you’re essentially sending new ‘troops’ to your gut, helping it work better.

    This will translate to your cognitive function and mood. As we saw, it’s well-known that a healthy gut contributes to a healthy brain. (5)

    This probiotic blend contains the following bacteria:

    • Lactobacillus acidophilus DDS-1

    • Lactobacillus Plantarum
    • Lactobacillus rhamnosus
    • Bifidobacterium lactis

    Prebiotic Blend

    You’ll get 2 capsules of the prebiotic blend per packet.

    Whereas the probiotic blend brings new troops (friendly bacteria) to your gut, the prebiotic blend focuses on strengthening the existing microflora. Prebiotics are essentially food for your friendly bacteria. They enable them to grow stronger and more diverse. (6)

    Two key probiotics in this probiotic blend are:

    • Organic Jerusalem Artichoke Root Extract (900 mg)
    • Organic Dandelion Root (600 mg)

    Anything Missing?

    Not really. Onnit Total Gut Health is a complete digestive formula. It has all you’d want from this kind of supplement and more. Not only does it improve your food absorption, but it also enhances your gut health and promotes overall digestion.

    How to Take (Dosage)

    You’re instructed to take one packet (7 capsules) with your largest meal of the day. This will help you better utilize the nutrients and will ensure that the friendly bacteria safely arrive to your gut.

    If you have gut issues or disbalance in your microflora. It’s possible to experience some slight bloating for the first few times after taking Onnit Total Gut Health. This is expected in some users, it simply means the bad bacteria are dying off whilst the friendly guys are taking hold.

    With that said, consult your doctor if you have any doubts or experience any significant side effects. Also, don’t take any supplement, including this one, if you have or suspect a medical condition. It’s always best to get a go-ahead from a professional instead of trying things on your own!

    Side Effects

    As we mentioned, it’s possible to get bloating when introducing new friendly bacteria, or strengthening the existing ones in your gut.

    In most cases though, Onnit Total Gut Health will not lead to any side effects. It uses proven and safe ingredients that only very sensitive people might react to.

    However, as much as this product is about improving your gut health, you should make sure to eat a healthy diet. And avoid foods that could counteract its benefits. Avoid taking Onnit Total Gut Health with these foods and beverages:

    • Any kind sugar, including honey
    • Beer
    • Wine
    • Corn oil
    • Liquors
    • Artificial sweeteners
    • Horseradish
    • Rice
    • Cured Meats
    • Barley
    • Oats

    Consuming any of these together with the product might lead to food intolerance, bloating, or constipation. Worse still, it could completely block the beneficial effects of Onnit Total Gut Health.

    That’s why we’ve repeated in this Onnit Total Gut Health review that no supplement can replace a balanced diet.

    Conclusion to Onnit Total Gut Health Review

    Taking a gut health supplement can benefit all aspects of your health. From digestion, the immune system to your brain. All of the nutrients go through your gut. If the gut doesn’t work well, your cognitive strength could suffer because of it.

    Because the gut has such a profound impact on our mental state, taking a product like Onnit Total Gut Health can be just as important as taking let’s say, a nootropic.

    The difference is, you won’t notice the effects of a gut supplement immediately. Give it at least a week or so to start working. Hopefully, this Onnit Total Gut Health review provided you with the answers you were looking for.

    In any case, it’s a 5-star rating from us.
