What’s Inside Total Gut Health?

How Can ONNIT Gut Health Help You Achieve Good Digestion 6

Total Gut Health has dozens of active ingredients that work together to give you healthier digestion. This includes:

  • Digestive enzymes
  • Probiotics
  • Prebiotics
  • Betaine HCl
  • Healthy yeasts

DIGESTech® Power Blend

DIGESTech® is a proprietary blend of digestive enzymes. 

It has the same compounds as ONNIT DIGESTech® and works similarly. Its primary ingredients are amylase, protease, and lipase. 

Other digestive enzymes are included in the blend, such as:

  • Alpha-galactosidase
  • Beta-glucanase
  • Cellulase
  • Glucoamylase
  • Hemicellulase
  • Invertase
  • Lactase
  • Maltase
  • Pepsin
  • Phytase
  • Serrapeptidase
  • Xylanase

Digestive enzymes break down the carbohydrates, proteins, fats, and plant fibers in food. This makes it easier to absorb their nutrients.

DIGESTech also contains organic ingredients for enhanced digestion. These include organic fennel seed powder and ginger root extract.

Fennel seed stimulates the production of bile and digestive enzymes. It relaxes the gut, reduces gas, and relieves irritable bowel syndrome (IBS).2,3

Ginger root offers many gastrointestinal benefits. It inhibits gut bacteria and nausea and speeds up food digestion.4

ONNIT Probiotic Blend

The proprietary blend contains five probiotics:

  • Lactobacillus acidophilus DDS-1
  • Lactobacillus plantarum
  • Lactobacillus rhamnosus
  • Bifidobacterium infantis
  • Bifidobacterium lactis

These probiotic strains are resistant to stomach acids. This allows them to reach the gut safely after the supplement is consumed.

Probiotics are “good” bacteria that aid food digestion and nutrient absorption. Some produce nutrients when they digest certain foods. 

They maintain a healthy gut flora by controlling the “bad” bacteria. Probiotics also help with other digestive problems, such as:5,6

  • Crohn’s disease
  • Diarrhea
  • Gut infections caused by Clostridium difficile
  • Irritable bowel syndrome (IBS)
  • Ulcerative colitis
  • Ulcers caused by Heliobacter pylori

ONNIT Prebiotic Blend

A packet of Total Gut Health will also include these prebiotics:

  • Organic Jerusalem artichoke
  • Organic dandelion root

Prebiotics are usually high-fiber foods that nourish healthy gut bacteria. Scientists believe they encourage probiotic growth and activity.

They’re different from probiotics, something they’re often confused for or conflated with. Here’s the difference between probiotics vs. prebiotics.

Prebiotics can also restore the population of good bacteria in your gut.7,8 

Betaine HCl

Betaine hydrochloride (HCl) stimulates the production of hydrochloric acid, an essential component of gastric juices.

Together with digestive enzymes and other substances, stomach acids can:9 

  • Break down food in the stomach
  • Prepare food for digestion in the intestines
  • Aid in the absorption of nutrients
  • Kill bacteria in food

Saccharomyces Boulardii

S. boulardii is an acid-resistant yeast. It can make its way to your gut without getting damaged in the stomach.

It’s gut-friendly and has probiotic qualities. It can help with many digestive problems, including:10

  • Chrohn’s disease
  • Irritable bowel syndrome (IBS)
  • Lyme disease
  • Traveler’s diarrhea
  • Ulcerative colitis

S. boulardii can also treat and prevent different types of diarrhea. This includes traveler’s diarrhea and diarrheas caused by rotavirus and harmful bacteria.10

Some people even use it for lactose intolerance.10

My Total Gut Health Review — Pros & Cons

I took the Ombre Gut Test a few months ago. My gut report said I was deficient in Bifibacterium and Lactobacillus, among others.

How Can ONNIT Gut Health Help You Achieve Good Digestion 7

To be fair, there’s no way for me to tell if my “bacteria level” is factual. But I did experience some symptoms associated with gut imbalance, such as:

  • Diarrhea
  • Fatigue
  • Poor sleep
  • Anxiety
  • Dry and itchy skin

I didn’t get the chance to try Ombre’s personalized probiotics, so I tried Total Gut Health instead. I used it for two weeks to see if it could help with my symptoms.

Things I Like About Total Gut Health

Here’s what I liked about ONNIT’s digestive supplement:

1. Minimal waste packaging

ONNIT Total Gut Health doesn’t come in plastic bottles, which I thought was strange. Instead, you get a box about the same size as a box of tea bags.

I eventually learned to love its packaging. While not 100% made of zero-waste materials, it’s still less wasteful than the usual bottle.

2. Tasteless and easy to consume

The capsule supplement has a reasonable size and smooth surface. You can easily swallow it even without water. 

It’s also tasteless and doesn’t leave an unpleasant aftertaste.

3. Safe for most diets

I personally don’t follow any diet, so I’m not picky with what I eat. That said, Total Gut Health is a good option for people with:

Since it’s soy-free, the supplement may also benefit people with hormonal imbalances that worsen with soy intake.

4. Not just a probiotic

Total Gut Health is an all-around digestive health supplement. To start off, it contains digestive enzymes and betaine hydrochloride. 

This makes food absorption easier for your digestive tract.

It has probiotics to promote healthy gut flora. Prebiotics also provide “food” for probiotics so they can thrive and support your digestion. 

Finally, it can help restore populations of good bacteria. Certain antibiotics can kill gut bacteria, whether beneficial or harmful.7,8

5. It uses clinically-supported ingredients

One of the company’s biggest claims is that Total Gut Health boosts your immune system.1 It seems far-fetched, but there’s science to back it up.

Studies show that a diverse gut flora regulates immune function. The immune system doesn’t work properly if gut bacteria is imbalanced.11

All other ingredients in the supplement are also supported by scientific research. 

(You can jump to the What’s Inside Total Gut Health section of my review if you missed it.)

6. It relieved my digestive issues

I took a packet (seven capsules) at lunch for two straight weeks. I didn’t feel much difference on the first three days of taking ONNIT Gut Health.

However, by day four, my bloating and flatulence were reduced. I also had less frequent bouts of diarrhea and constipation. 

Before taking the supplement, these issues used to be more frequent.

My bowel movements felt more normal towards the end of the first week. They weren’t regular, but I felt more at ease whenever I took bathroom trips.

By the second week, I started passing stool more regularly. And while it didn’t help with all of the symptoms, I felt better overall.

7. It’s made by a company that values top-tier quality

ONNIT ensures the quality of its products with these steps:

  • Ingredients come from partner farms with sustainable and humane practices
  • Products are manufactured at ONNIT’s location in Austin, TX
  • Third-party labs test products for contaminants and banned substances

Many of ONNIT’s products have the Rainforest Alliance Seal. This suggests they are socially, economically, and environmentally sustainable.

8. You get more bang for your buck

Ombre Probiotics are more affordable than Total Gut Health. That said, Total Gut Health gives you more value for your money.

If you compare their ingredients, Ombre is a single-strain probiotic supplement. The company’s only advantage is that it offers gut microbiome testing.

Total Gut Health is a complete gut health supplement that promotes overall digestive health. This makes it worth the extra cost.

Things I Don’t Like About Total Gut Health

Here’s what I didn’t like about ONNIT’s gut supplement:

1. It isn’t tailored to your needs

Total Gut Health is an over-the-counter digestive health supplement that you can buy online.

While it uses clinically proven ingredients, it has a generic formula that ONNIT expects to work on everyone.

It’s not like Ombre or Viome Gut Tests, both of which offer personalized probiotic recommendations based on your gut bacteria.

2. That’s a lot of capsules

Taking one to two capsules of your favorite supplement seems like a standard requirement. But ONNIT doesn’t ask you to take only one pill. 

You have to take seven capsules with the heaviest meal of your day. Anyone will agree it’s too much in one sitting.

Is Total Gut Health Supplement Safe?

Yes. ONNIT Total Gut Health should be safe to use. 

Many of its active ingredients exist naturally in your body. Those that don't (like prebiotics) are derived from natural foods.

ONNIT follows industry-grade standards to make sure they provide you with safe and sustainable products. Their supplement contains ingredients that are:

  • Caffeine-free
  • Dairy-free
  • Keto-friendly
  • Soy-free
  • Vegan

So, if you have a specialized or restrictive diet, you can take it with your food.

Total Gut Health is not approved by the U.S. Food and Drug Administration (FDA). However, since it’s a dietary supplement, it doesn’t require FDA approval.5

Just remember not to use this product to treat, cure, or prevent any disease, nor should you use it to replace medical treatments.1

Talk to your doctor before taking ONNIT or any nutritional supplement, especially if you’re pregnant, nursing, taking medications, or have a medical condition.

How to Use ONNIT Gut Health Supplements

If you’re an adult, you can take one (1) packet each day with your largest meal.

To use: Simply open the packet and consume all 7 capsules inside it. You can take them minutes before a meal, so the ingredients have time to take effect.

ONNIT recommends storing the supplement in a cool, dry place.1

How Much Does Total Gut Health Cost?

ONNIT sells its dietary supplement in boxes. One (1) box may contain 15 or 30 counts (cts) or packets with seven (7) capsules each.

Each count or packet includes one (1) serving and will only last a day. You can buy ONNIT Total Gut Health one-time for these prices:

  • 1 box of Total Gut Health (15 cts) — $37.95
  • 2 boxes of Total Gut Health (30 cts) — $75.90

Subscribers can ask to have ONNIT’s supplements delivered every 7 to 90 days. You also get a 15% discount, reducing its cost to $32.26 for 1 box and $64.52 for 2 boxes.

ONNIT offers free shipping for orders worth $150 and a free supplement for orders worth $200.

Are ONNIT Gut Supplements Worth It?

How Can ONNIT Gut Health Help You Achieve Good Digestion 5

Many people take their digestive system for granted. Keep in mind that every food we ingest has to pass through it.

Unless you keep it healthy, the nutrients we get from foods can go to waste.

Research on the gut microbiome continues to increase. So far, it reveals the profound impact that gut health can have on several different aspects of one's health

Elise Harlow, M.S., R.D.N.

ONNIT Total Gut Health can keep our digestive tract in shape and maintain healthy gut bacteria. 

Because of these, it can provide its promised health benefits such as:

  • Immune system support
  • Digestion of major macronutrients
  • Absorption of micronutrients

When paired with a healthy diet, you can get the most out of gut health supplements.
