Advanced Plant Peptides

Just like proteins, peptides are made up of amino acids; they’re just smaller. Whereas proteins are typically made up of 50 or more amino acids, peptides contain between 2 and 50. Researchers are finding that the smaller these molecules are, the more targeted their function. Peptides help maintain, reinforce, and repair your gut barrier, which protects you from the germs and toxins in your food and environment.* Peptides also provide antioxidant support to protect the structures of your gut from free radical attack.* Additionally, they help regulate important processes, including detoxification — one of the major functions of the gut.*

Activated Enzyme Blend

Enzymes are simple proteins found within each living cell. There, they spark various biological reactions, including digestion. Previlli’s Activated Enzyme Blend contains digestive enzymes that help break down all components of food — protein, carbohydrates, starches, fats, fiber, and sugar. As a result, it reduces bloating, abdominal discomfort, gas, and toilet trouble, while also supporting enhanced nutrient absorption.*

Immunell™ Nucleotides

Found in certain foods, breast milk, and all living cells, nucleotides are small, biological molecules that are critical to many physiological processes. These plant molecules provide building blocks for the fast-renewing tissues of your gut and immune system.* That’s important, since your gut is constantly shedding millions of worn out old cells and replacing them with shiny new ones. In fact, it takes just 2-4 days for the cells of your gut lining to turn over!


This amino acid occurs in the same plants where caffeine is found. It counteracts the effects of caffeine, because it has a calming effect on the brain.* But L-theanine is not a sedative. In fact, it activates mental energy, attention, and focus.* L-theanine also supports important elements of core gut architecture.* For instance, it benefits the gut microvilli, which are responsible for nutrient absorption.*

Polyphenol Blend

Polyphenols are healthful compounds found in plant foods. They support the structures and functions of your gut in numerous ways.* Polyphenols reinforce your gut barrier, act as a food source for good gut bacteria, and provide powerful antioxidant capacity to protect your core gut architecture — the actual anatomy of your gut.*

Apple fruit extract (75% polyphenols), Cranberry fruit (6% quinic acid), Purple Sweet Potato fruit (2.5% anthocyanins), Mango leaf extract (95% mangiferin), Indian Barberry bark extract (97% berberine), Cocoa seed extract (providing 12% theobromine), Quercetin, Avocado fruit extract, Skullcap root extract (85% baicalin), Passion Flower extract (3.5% flavonoids, Blueberry fruit extract (2.5% anthocyanins), Pomegranate fruit extract (40% punicalagins), Puredia Seaberry™ (Sea Buckthorn fruit), Turmeric rhizome extract (95% curcuminoids).


Typically, prebiotics act as food for beneficial gut bacteria, increasing their numbers. This prebiotic works in a completely unique way. It attaches to unwanted bacteria and destabilizes their cell walls, making room in your GI tract for the good guys.* In a human clinical study, PreforPro® was shown to positively influence the microbial population of the gut, while also producing beneficial effects on cholesterol and immune response.*


How much you weigh is associated with the composition of your gut bacteria. People with more gut bacteria from the Bacteroidetes phylum and fewer from the Firmicutes phylum tend to be slimmer on average than folks with the reverse ratio. That’s probably because Firmicutes bacteria can extract up to 30% more calories from the same gram of food! PrecticX™ is a prebiotic fiber that shifts the balance of gut bacteria to favor those found in leaner individuals, so you absorb fewer calories from your food.  Learn More

Proprietary Fermented Superfood Infusion

Superfoods are whole foods, typically derived from plants, that are naturally exceptionally high in nutritional value. When foods are fermented, their nutrients become more bioavailable, meaning your body absorbs even more of the goodness they contain. Fermented superfoods also have a prebiotic effect, because they act as a healthy snack for your microbiota.*

This organic trace mineral complex may improve the length of your microvilli, tiny gut structures that increase your gut surface area and aid nutrient absorption.* Unlike macro-minerals, which your body needs in larger quantities, trace minerals are so powerful, they are only needed in small amounts.

Vitamins and Minerals

  • Vitamin A: This essential vitamin is necessary for manufacturing mucin, which covers the cells of your gut barrier in a gooey film that’s like a fly trap for germs and toxins.*
  • Vitamin D: This essential vitamin plays a role in your mucosal immune system, which guards the vast surface area of your GI tract against invaders.*
  • Pantothenic acid: This essential vitamin (B5) helps turn the food you eat into the energy you need.*
  • Zinc and Selenium: These essential minerals are needed for gut health; deficiencies in either mineral can increase your gut permeability.*
