Why Choose Bio-Avail Myco?

Contains REAL Mushrooms—Not Mycelium Grown in a Lab

Bio-Avail Myco is made with real mushrooms grown primarily outdoors on natural substrates like wood logs. This is how mushrooms have been cultivated for thousands of years, and it leads to higher concentrations of active ingredients like beta-glucans, and lower levels of inactive ingredients like starch (e.g. alpha-glucan). In contrast, many popular mushroom products are not truly mushrooms, but mycelium (a different stage of the fungal lifecycle) grown in a lab on cereal grains, sawdust, straw, or compost.

Full-Spectrum Formula

Superfood mushrooms in a single, full-strength formula 

Bio-Avail Myco is a blend of mushrooms that have shown the greatest health benefits in scientific studies: reishi, chaga, lion’s mane, cordyceps, maitake, shiitake, tremella, and turkey tail. Each daily serving contains over 1,500 mg of mushrooms, which means you’re more likely to enjoy the broad spectrum of benefits that mushrooms offer. Cordyceps, reishi, and chaga are offered in an 8:1 extraction, increasing their potency and effectiveness. 

Rich Source of Beta-Glucans

A Rich Source of Beta-Glucans, Terpenes, and Other Healing Compounds

Bio-Avail Myco provides high levels (362 mg per serving!), a type of soluble fiber that promote optimal immune function, support the gut microbiota, and help maintain normal blood sugar and cardiovascular health. It also features a broad spectrum of terpenes, phenolic compounds, and essential vitamins and minerals. By using real mushrooms grown on natural substrates (rather than mycelium grown on grain in a lab), we’re able to maximize the amount of these healing compounds.

Good For You—And the Planet

You can’t have healthy humans without a healthy planet. That’s why Adapt Naturals is working toward zero plastic and landfill waste in our supply chain.

In the fall of 2023, we started transitioning our packaging to 100% compostable, stand-up pouches. They’re made from cellulose (wood pulp) and are free of PLA, BPA, PFAS, phthalates, and other harmful chemicals. They’re printed with non-toxic, compostable ink. The pouches are so clean and biodegradable that you can put them in your backyard or curbside compost bin! 

Our sustainable packaging initiative will prevent over 120,000 plastic bottles from ending up in a landfill or the oceans. Thank you for being part of the solution and helping Adapt Naturals protect the beauty of our natural environment!

Your Questions Answered

Bio-Avail Myco is best taken with food. We recommend taking two capsules in the morning with breakfast and two capsules in the evening with dinner.

We know that some people don’t enjoy the taste or texture of mushrooms—which is one of the reasons we made this supplement. You can get the benefits of eating these powerful superfoods without preparing or tasting them!

Most people see positive changes like more energy, smoother digestion and elimination, stronger immunity, clearer skin, and better mental and physical performance within a couple of weeks. 

That said, individual responses can vary based on several factors. We suggest giving Bio-Avail Myco at least three months before determining whether it is working for you.

Bio-Avail Myco is manufactured in a U.S. facility that meets the NSF’s rigorous GMP (Good Manufacturing Practices) regulatory standards.

The mushrooms in Bio-Avail Myco have a wide range of potential benefits, but in some cases, these changes can take time to develop. For this reason, we suggest that you take Bio-Avail Myco for at least three months before you determine whether it works for you. 

That said, we know that each individual is different, and we want you to be completely satisfied with your purchase. If you’re unhappy with your order for any reason, simply contact us and we’ll give you a full refund with no questions asked.

2022 study published in the journal Frontiers of Microbiology found that mushrooms are rich in essential nutrients (vitamins B1, B2, C, D, and E) and are a good source dietary of fiber, minerals (especially zinc, copper, iron, phosphorus, and potassium), trace elements, and proteins (including essential amino acids). 

Mushrooms are one of the highest dietary sources of beta-glucans, a special type of soluble fiber that is being intensively studied for its benefits on the immune, cardiovascular, endocrine, and neurological systems.

Mushrooms also contain terpenes and phenolic compounds. You might be familiar with these compounds from other plants. For example, the terpenes in the cannabis plant have received a lot of attention over the past few years, and the essential oils in plants like lavender and mint are mostly made up of terpenes.

Research on the terpenes in mushrooms is still ongoing, but studies have already shown tremendous potential benefits for immune, digestive, brain, metabolic, and heart health.
