You’ve swapped your regular coffee for a mushroom-infused brew, hoping to tap into the cognitive-enhancing, stress-reducing, and immune-boosting power of functional fungi. But are you actually getting all the benefits you’re paying for? The secret lies in a complex-sounding but crucial concept: bioavailability.
Simply put, bioavailability is the degree to which a substance is absorbed and used by the body. When it comes to mushroom coffee, it’s the key that unlocks the full potential of every cup. You can have the most potent Lion’s Mane or Reishi, but if your body can’t absorb the active compounds, you’re missing out on the magic.

In this deep dive, we’ll explore the science behind mushroom coffee bioavailability, from the critical role of extraction methods to the best time to drink your brew for maximum absorption. Get ready to become a more informed consumer and unlock the true power of your functional mushroom habit.
The Science of Bioavailability: Why Extraction is Non-Negotiable
To understand mushroom coffee bioavailability, we first need to talk about chitin. The cell walls of mushrooms are made of this tough, fibrous substance—the same material that makes up the exoskeletons of insects and crustaceans. Our bodies lack the enzyme chitinase, which is needed to break down chitin effectively. [2]
This means that if you were to simply grind up raw mushrooms and put them in your coffee, you wouldn’t be able to access most of their beneficial compounds. The beta-glucans, triterpenes, and other powerful phytonutrients would remain locked away inside the indigestible chitin.
This is where extraction comes in. As Skye Chilton, a mushroom expert at Real Mushrooms, explains:
“By using common extraction techniques, we can break down this chitin and give our bodies easier access to the beneficial compounds.” [2]
Extraction is the process of using solvents—typically hot water, alcohol, or a combination of both—to dissolve the chitin and release the bioactive compounds. This makes them bioavailable, meaning your body can absorb and utilize them.

Without a proper extraction process, you’re essentially drinking expensive fiber. This is why it’s crucial to choose a mushroom coffee that uses high-quality, professionally extracted mushroom powders. The difference in bioavailability is significant, and it’s what separates a truly functional beverage from a marketing gimmick.
Hot Water vs. Dual Extraction: Which Unlocks More Benefits?
Now that we know extraction is essential, let’s get into the specifics. You’ll often see mushroom products labeled as “hot water extract” or “dual extract.” The method used can dramatically impact which compounds you’re getting.
Hot Water Extraction
This is the most common and traditional method. Think of it like making tea. The mushrooms are simmered in hot water for an extended period, which dissolves the water-soluble compounds. This method is particularly effective for extracting beta-glucans, the powerful polysaccharides known for their immune-modulating and anti-inflammatory properties.
For mushrooms like Lion’s Mane, Cordyceps, Turkey Tail, Shiitake, and Maitake, a hot water extraction is often sufficient, as their primary active compounds are water-soluble. [2]
Dual Extraction
Dual extraction involves a two-step process: first, an alcohol extraction, followed by a hot water extraction. The alcohol is used to pull out the non-water-soluble compounds, such as triterpenes and sterols. These compounds are responsible for many of the adaptogenic and cognitive benefits found in mushrooms like Reishi and Chaga.
However, there’s a crucial trade-off. The alcohol used in dual extraction can cause the beta-glucans to precipitate (solidify) and be filtered out. Research from Nammex, a leading mushroom ingredient supplier, shows this can lead to a significant loss of these vital polysaccharides. In one test, a Reishi hot water extract contained 26.23% beta-glucans, while a dual extract of the same mushroom had only 5.5%. [2]
The Takeaway: For Reishi and Chaga, a dual extract is necessary to get the full spectrum of benefits, including the valuable triterpenes. For most other functional mushrooms, a high-quality hot water extract will provide a more potent dose of beta-glucans. At Vital Pour, we believe in using the right extraction method for each mushroom, which is why our Clarity Brew is formulated to maximize the bioavailability of every ingredient.
Timing Your Sip: When to Drink Mushroom Coffee for Maximum Absorption
Beyond the extraction method, when and how you drink your mushroom coffee can also influence its bioavailability. While research is still emerging, some general principles can help you get the most out of every cup.
Morning vs. Evening
Most experts recommend drinking mushroom coffee in the morning or early afternoon. This is partly due to the caffeine content, which can interfere with sleep if consumed too late in the day. However, there’s also a connection to our natural circadian rhythm. Some studies suggest that consuming adaptogens in the morning can help regulate our stress response throughout the day.
For those looking to enhance focus and mental clarity with mushrooms like Lion’s Mane, a morning dose makes perfect sense. It can help you start your day with a cognitive edge. If you're using mushroom coffee for its calming and sleep-promoting benefits (from mushrooms like Reishi), you might consider a decaffeinated version in the evening. However, be mindful of the potential for digestive upset, as we'll discuss next.
With or Without Food?
This is a topic of much debate. Some sources suggest that taking mushroom supplements on an empty stomach can lead to faster absorption. The logic is that without any other food to compete with, the active compounds can be more quickly processed by the body.
However, for some people, consuming mushroom extracts on an empty stomach can cause digestive discomfort or nausea. This is particularly true for those with sensitive stomachs. A 2024 study published in Pharmaceuticals noted that polysaccharides in mushrooms can sometimes cause adverse effects in individuals with conditions like SIBO (Small Intestine Bacterial Overgrowth). [1]
Furthermore, some compounds are fat-soluble, meaning they are better absorbed when consumed with a source of fat. For example, the triterpenes in Reishi and Chaga may have enhanced bioavailability when taken with a meal that includes healthy fats like avocado, nuts, or olive oil.
Our Recommendation: Listen to your body. If you tolerate mushroom coffee well on an empty stomach, that may be the most efficient way to absorb its benefits. If you experience any discomfort, try having it with a light breakfast. The most important thing is consistency. As a registered dietitian quoted by the Cleveland Clinic advises, tracking your symptoms is key to finding what works best for you.

The Bottom Line: Making Every Sip Count
Unlocking the full potential of your mushroom coffee comes down to more than just the mushrooms themselves. It’s about understanding the science of bioavailability and making informed choices. From ensuring your product uses proper extraction methods to experimenting with timing and food pairings, you have the power to maximize the benefits of your daily ritual.
Remember, not all mushroom coffees are created equal. Look for brands that are transparent about their extraction methods and provide third-party testing to verify the levels of active compounds like beta-glucans and triterpenes. While the research on mushroom coffee specifically is still growing, the evidence is clear: the quality and processing of the mushroom extracts are paramount.
As the Cleveland Clinic notes, while the hype may be ahead of the science, there’s little harm in trying mushroom coffee if you’re curious and don’t have any underlying health issues. [3] By applying the principles of bioavailability, you can ensure you’re not just drinking a trendy beverage, but truly investing in your well-being.
