Vesper Mushrooms, a Portland, Oregon-based supplement brand, sells its Gut-Brain Axis Bundle as a pairing of two liquid double-extract tinctures: Lion's Mane and Turkey Tail. The brand's pitch is straightforward — "your brain and your gut talk to each other more than most people do," and this bundle is framed as supporting that connection.
According to Vesper, Lion's Mane is included for its associations with neuroplasticity, memory, and focus, while Turkey Tail is included for gut microbiome and immune support. Both extracts are made from fruiting-body-only mushrooms — no mycelium or grain fillers, per the brand — infused with wild huckleberries, and dual extracted for bioavailability. Ingredients listed are Lion's Mane and Turkey Tail fruiting body extract, wild huckleberry, distilled water, and organic wheat ethanol. Vesper states its mushrooms are grown in-house in the USA and third-party tested for purity, though these are brand claims rather than independently verified certifications.
The bundle is listed at 1.707.000₫, discounted to 1.573.000₫ (roughly USD $64 down to $59 at current conversion rates, though actual checkout currency may differ by region), and currently shows a 5.0 rating on the product page. Suggested use is 1–2 full droppers of each extract daily, taken under the tongue or mixed into tea or a smoothie.
For shoppers already interested in functional mushroom supplements, this bundle offers a two-in-one entry point covering both cognitive and gut-health angles rather than committing to a single extract. As with any supplement, it's worth checking in with a healthcare provider before adding it to a routine, especially alongside other medications.
