The vagus nerve is the highway between your gut and your brain. Viva Vagus supports both ends of that connection - three full-spectrum mushrooms for gut immunity and microbiome support, fermented glutamine for gut lining health, and magnesium glycinate for the nervous system calm that healthy digestion depends on.
- Digestive comfort - Less bloating, more ease, digestion that works the way it should
- Balanced gut - Smoother, more regular digestion as the microbiome finds its rhythm
- Immune resilience - The daily defense that comes from a well-supported gut-immune foundation
- Gut-brain harmony - A calmer gut contributing to a clearer, more settled mind
56 capsules | 4 Week supply (2 capsules daily)
For decades, gut health focused on probiotics and digestive enzymes. Add the good bacteria. Help break down the food. Both useful but they miss the upstream systems that determine whether the gut environment can actually support a healthy microbiome in the first place.
- Three full-spectrum mushrooms working as a system - Turkey Tail as a prebiotic fiber source, Chaga for antioxidant and cellular support, Reishi for immune balance and nervous system calm. The complete mushroom gut-immune foundation.
- Fermented Glutamine - The primary fuel source for gut lining cells. Fermented rather than synthetic - the form closest to what the body produces naturally. The gut lining support layer most formulas skip.
- Magnesium Glycinate for the gut-brain connection - Supports nervous system calm and the healthy gut motility that proper digestion depends on. The link between a settled nervous system and a settled gut.
- The vagus nerve angle - 80% of gut-brain communication travels through the vagus nerve. Viva Vagus is built around that pathway - supporting both the gut environment and the nervous system calm that vagal function depends on.
2 Capsules P/Serving | Total Serving (1405mg)
Turkey Tail - Full Spectrum (300mg) - The prebiotic foundation of the formula. Turkey Tail's PSP and PSK polysaccharides function as a natural prebiotic fiber selectively feeding beneficial bacteria including Lactobacillus and Bifidobacterium species. A well-fed microbiome supports both digestive health and the immune function that 70 to 80% of the body's immune system depends on through the gut-associated lymphoid tissue. Full spectrum fruiting body and mycelium for the complete PSP and PSK profile
Fermented Glutamine (400mg) - Glutamine is the primary fuel source for enterocytes the cells that line the gut wall and form the barrier between the digestive tract and the bloodstream. Fermented rather than synthetic produced through a natural fermentation process that produces a form the body recognises more readily. Supports the gut lining cellular health that a healthy microbiome environment depends on.
Chaga - Full Spectrum (250mg) - Antioxidant and cellular protection support for the gut environment. Chaga's polyphenols, melanin, and beta-glucans support the body's antioxidant defense in the gut — relevant because the gut is one of the highest-oxidative-stress environments in the body. Also contributes immune support alongside Turkey Tail. Full spectrum for the complete bioactive entourage including betulinic acid and inotodiol.
Reishi - Full Spectrum (250mg) - The immune balance and nervous system calm layer of the formula. Reishi supports the immune modulation that keeps the gut immune environment well-calibrated — neither underactive nor overactive. Also supports nervous system relaxation through its adaptogenic compounds, contributing to the parasympathetic state that healthy digestion and gut motility depend on. Full spectrum for the complete triterpene and beta-glucan profile.
Magnesium Glycinate (200mg) - The gut-brain connection mineral. Magnesium supports nervous system calm and healthy gut motility the rhythmic muscle contractions that move food through the digestive tract. A settled nervous system supports better digestion. Magnesium Glycinate is used specifically because it is one of the most bioavailable forms and does not cause the digestive sensitivity that oxide forms can. It is the nervous system foundation that the rest of the formula builds on.
Black Pepper Extract (95% Piperine) (5mg) - Bioavailability support for the whole formula particularly the mushroom compounds and magnesium. A small but meaningful dose ensuring the formula reaches concentrations that matter.
2 capsules daily with or before food.
Morning with breakfast is the primary recommendation gut and immune support building through the day. After lunch also works well for digestion support specifically.
1. Morning with breakfast - Take with food for best absorption of the mushroom compounds and to support the gut environment from the start of the day. The prebiotic fiber from Turkey Tail starts feeding the microbiome with the first meal.
2. After lunch option - For digestive and nervous system support specifically, taking after the main meal of the day activates the gut-brain connection support during the period when the digestive system is most active. Works particularly well on higher-demand days.
3. The evening tea ritual - Pop the capsules open and combine with Deep Dream in hot water as an evening tea. The Reishi and Magnesium Glycinate in Viva Vagus and the botanical calm blend in Deep Dream create a genuinely effective wind-down ritual that supports both gut health and sleep quality simultaneously.
4. Be consistent - Microbiome support and gut lining health both build cumulatively. The prebiotic fiber needs consistent feeding to shift the microbiome meaningfully. Most people notice the clearest difference after 3 to 4 weeks of daily use.
Stacks well with: Turkey Tail standalone for additional PSP and PSK prebiotic fiber support. Chaga for a complete antioxidant and cellular protection foundation. Peace or Shine for a complete gut-nervous system daily protocol. Deep Dream in the evening for the full gut-brain wind-down ritual.
Gut immunity & microbiome support
Turkey Tail and Chaga work together on the gut immunity layer. Turkey Tail's PSP and PSK polysaccharides act as prebiotic fiber —selectively feeding beneficial bacteria that support both digestive health and the gut-associated immune function that 70 to 80% of the body's immune system depends on. Chaga contributes antioxidant and cellular support to the gut environment. Together they create the microbial and immune foundation that everything else in Viva Vagus builds on.
system calm
Vagus nerve and nervous system calm. Reishi and Magnesium Glycinate support the nervous system calm that healthy digestion depends on. The vagus nerve carries 80% of gut-brain communication and most of it travels upward, from gut to brain. Reishi's adaptogenic compounds support the parasympathetic nervous system state that vagal function and healthy gut motility depend on. Magnesium Glycinate supports nerve signaling and the muscular relaxation involved in smooth digestive movement. A settled nervous system supports a settled gut.
Gut lining health
Fermented Glutamine supports the cellular health of the gut lining the barrier between the digestive tract and the bloodstream. Enterocytes, the cells that form this lining, use glutamine as their primary fuel source. Supporting gut lining cellular health contributes to the environment where a healthy microbiome can establish and a healthy immune response can be mounted. Fermented form for the closest-to-natural bioavailability.
Antioxidant support
The gut is one of the highest-oxidative-stress environments in the body constant exposure to food, bacteria, and metabolic processes generates significant oxidative load. Chaga's antioxidant compounds and Reishi's beta-glucans support the body's natural oxidative defense in the gut environment. This is the cellular protection layer that supports the long-term gut health that short-term probiotic use alone cannot provide.
Gut motility & digestive balance
Gut motility the rhythmic muscular contractions that move food through the digestive tract is regulated by both the enteric nervous system in the gut and the vagal signals from the brain. Supporting both the nervous system calm and the mineral foundation that motility depends on addresses digestive regularity at the source rather than symptom by symptom.
Foundation
The foundation everything else builds on.
The gut is not just a digestive organ. It is where 70 to 80% of the immune system lives. Where the vast majority of the body's serotonin is produced. Where the microbiome communicates with the brain through the vagus nerve. Supporting gut health supports immune resilience, nervous system balance, and cognitive clarity simultaneously — not because the gut directly causes all of these, but because a healthy gut environment creates the conditions where all of them function better.
