Professional Grade Natural Digestive Enzymes

DIGESTech® represents one of the most powerful digestive enzyme combinations on the market today. Increasing the natural enzyme levels in the stomach, it not only  break down food — helping to ease any bloating or discomfort associated with a large meal — but DIGESTech® also assists with enzymes specifically chosen to help digest all five of the major food categories — including fats, protein, carbs, lactose from dairy, and fiber — this supplement is an all-in-one professional grade digestive enzyme formulation.†

Key Ingredients




A Protein Digesting Enzyme

Proteases are enzymes that break the peptide bonds that link amino acids into the polypeptide chains form proteins, and they can also help digest proteins, and other cellular debris.†




A Carbohydrate Digesting Enzyme

Complex carbohydrates — like those found in grains, nuts, seeds, legumes, and vegetables — are just long chains of sugar molecules linked together. Amylase helps break these down into glucose that your body can use for fuel.†




A Fat Digesting Enzyme

Dietary fats are too large for the body to absorb intact. Lipase enzymes break down these fatty triglycerides into monoglycerides and fatty acids that the body can then absorb through the intestinal lining.†

and 14 Other Powerful Digestive Aids:

  • Serrapeptidase
  • • Fennel Seed Powder
  • • Ginger Root Extract
  • • Pepsin
  • • Cellulase
  • • Invertase
  • • Lactase
  • • Maltase
  • • Glucoamylase
  • • Alpha Galactosidase
  • • Phytase/Pectinase
  • • Xylanase
  • • Hemicellulase
  • • Beta Glucanase

Total Feast

“I’ll have the 16oz grass-fed tomahawk ribeye medium-rare, with the potatoes au gratin, and the broccoli with bearnaise. And I’ll start with the french onion soup and the crab stuffed mushrooms, please. ” Whether it’s a steakhouse, neighborhood Italian, or even the best damn vegan tacos you’ve ever had, we’ve all had big meals that put our digestive systems to the test. And if you haven’t, please give the Dalai Lama our regards! The result of this culinary indulgence — often colloquially described as a ‘food coma’ — slows the body down to a crawl, resulting in reduced mental capacity, and drowsiness that rolls in like a fog. An exaggeration of these symptoms can be witnessed in the recovery periods of professional competitive eaters, often lasting up to 12 hours. One of the main problems is that the stomach simply does not have the enzyme capacity to digest such an overload of food. To make matters worse, pasteurization and cooking processes remove many of the natural enzymes contained within the food itself, hindering the digestion process. DIGESTech® taken at the start of the meal can make a huge difference in mitigating the downtime after a heavy meal, allowing you to enjoy an indulgent feast with a little less of the strain put on your alimentary system.†

I love DIGESTech® because I know we have those days when we overindulge. But when I take DIGESTech® before I dive into my monster size cheat meal, I don't feel as guilty, because I know I'm giving my digestive system some help breaking down those bad carbs, heavy dairy products, and empty calories.† I even take DIGESTech® when I'm eating healthy to keep me regular! It's one of my favorite supplements!!!

Every meal I eat includes Onnit’s DIGESTech® digestive enzymes. DIGESTech® makes a noticeable difference in my body’s ability to break down and absorb the nutrients in the food I eat. I’ve tried a number of different digestive enzymes on the market, and DIGESTech® is hands down the best you can buy!

Few things are as important to total well-being as digestive health. When your gut is unhappy, your entire body is unhappy. DIGESTech® helps support the digestive system safely and gently.

DIGESTech® breaks the food down in my stomach so I reap the benefits of improved digestion . DIGESTech® is a huge support in my physical performance.

This has sneaked into the #2 spot of my favorite supplements right behind Alpha BRAIN®. You need nutrients to recover, and I need to keep my bodyweight up. Weighing 230-250lbs takes a lot of food to maintain, especially when you're eating right. So DIGESTech® is HUGE in helping me with digestion after big post-workout meals, and it gets rid of the bloated feeling.

DIGESTech® Supplement Facts

DIGESTech® Ingredients


Serrapeptidase is commonly found in the silkworm helping it to breakdown its hard outer cocoon. In humans its been found to help breakdown non-living tissue and has shown anti-inflammatory properties.

Fennel Seed

Fennel seeds may provide quick and effective relief from many digestive disorders. Being rich in minerals like magnesium, they also include phytonutrients like Anethol that help to inhibit spasms in smooth muscle like the intestinal tract. And more recent studies have found consumption of fennel seeds to increase bile production and possess antimicrobial properties.

Ginger Root

Ginger root has been used as a tonic for improved digestion across cultures with a history going back to 3000 BC. Traditional uses include improved digestion, alleviating indigestion, easing nausea, vomiting, diarrhea, motion sickness, heartburn, and stomach cramps. Studies today show its effectiveness in reducing the severity of and duration of nausea. The two main phytonutrients gingerol and shogaol, are thought to stimulate the bodies flow of digestive fluids such as saliva, gastric juices, and bile.


Pepsin is a protease enzyme that breaks down proteins into polypeptides. Proteins are long peptide chains that take several stages to be broken down into their base constituent amino acids. Pepsin is the enzyme that creates those initial 'cuts.'


Amylase is an enzyme that breaks down starch into simple sugars. Complex carbohydrates like those found in grains, nuts, seeds, legumes, and vegetables are just long chains of sugar molecules linked together. Amylase helps break these down into glucose that your body can then use for fuel.


Protease are enzymes that break the peptide bonds that link amino acids into polypeptide chains forming proteins. That can also help digest the cellular walls of unwanted wastes like toxins, undigested proteins, and other cellular debris.


Dietary fats are too large for the body to absorb. Lipase enzymes break down these fatty triglycerides into monoglycerides and fatty acids that the body can then absorb through the intestinal lining.


The plants we eat have a cellular wall made primarily of cellulose, a fibrous matter that we as humans to do not create an enzyme to digest. So we have to rely on fermentation in the large intestine by our flora. Cellulase is an enzyme that breaks down cellulose into beta glucose.


Invertase breaks down sucrose into its parts, glucose and fructose. Combined with other carbohydrate digesting enzymes it can help enhance the overall digestion of starch, carbohydrates, and sugar.


Is a critical enzyme in breaking down the complex sugar lactose into glucose and galactose. Without lactase, lactose remains in your digestive tract undigested. Lactose is found in dairy products.


Maltose is a sugar that is produced as the body breaks down starches and complex carbohydrates. Maltase helps break down maltose into glucose relieving some of the burden on the pancreas and small intestine.


is a unique digestive enzyme in that it breaks off a free glucose molecule from long chain carbohydrates, starches, and maltose. Instead of breaking these long chains into smaller chains it simply 'cuts' a glucose from the end.

Alpha Galactosidase

Glycolipids are sugar-fat molecules found in foods like broccoli, cabbage, brussel sprouts, kidney beans, and lentils. These tend to be more challenging for the body to break down and can lead to gassiness and bloating. Alpha Galactosidase is an enzyme that breaks down this specific sugar-fat molecule.


Pectin is a type of polysaccharide that makes up the soft cell walls of fruits and vegetables. Think the inside of an apple. Pectinase helps digest this soft fiber cellular wall.


Is an enzyme that breaks down a specific component of a fiber called hemicellulose into a simple sugar called xylose.


Is an enzyme that helps break down hemicellulose, a type of cellulose fiber. Many common fiber rich breakfast cereals contain large amounts of hemicellulose. Hemicellulase is not produced in the human body so we rely on our intestinal flora to break it down.

Beta Glucanase

is a carbohydrate digesting enzyme that breaks down glycosidic bonds within beta-glucan. Glucans can create up to 60% of the cellular wall of many fungal organisms like Candida albicans, a major player in candida overgrowth in the G.I. tract.
