Real Quality

Why Beta-Glucans Matter

Beta-glucans are the primary active compounds in mushrooms that support immune function.* Most mushroom products don’t list beta-glucan content, but we do.

Beta-Glucans indicate an authentic mushroom product versus myceliated grain products that contain high levels of starch (Alpha-Glucans) instead.

Real Mushrooms offer potency you can trust, in every capsule.

We use only 100% mushroom (fruiting body)—no grain, no mycelium, no fillers.

This product has received the Purity-IQ™ Verified Mushroom Identity Certification—a cutting-edge genomic testing standard that confirms we use the correct mushroom species and nothing else.

Frequently Asked Questions

5 Defenders™ is a blend of organic mushroom extracts designed to help support overall well-being, resilience, and immune system health.

It is the product that most new customers begin with Real Mushrooms.

While single-mushroom supplements can be helpful for targeted needs, they often address just one slice of the wellness picture. Real Mushrooms' 5 Defenders™ blend, however, supports:

  • Innate and adaptive immune function†
  • Oxidative stress resilience†
  • Calm, balanced energy†
  • Gut and microbiome health (through Turkey Tail's prebiotic-like effects)†

The blend is derived from 100% organic mushrooms, not mycelium fermented grain, so you get potency without compromise: no starch, no fillers, just the active compounds your body can actually use.

Ergothioneine is a sulfur-based amino acid. Amino acids are important compounds that help the body build proteins. Ergothioneine was discovered in 1909 by Charles Tanret, a French pharmacist and chemist.

This compound holds powerful antioxidant potential, helping to protect cells from oxidative damage. Certain mushrooms, including some of our products, are known to contain high levels of ergothioneine naturally.

Tanret was examining the ergot fungus, which had recently been responsible for destroying crops, and he discovered the compound by using a purification process. The amino acid name ergothioneine originates from this fungus. While the ergot fungus may damage crops, the amino acid it contains helps essential functions in the human body.

All our mushroom extracts are from the leading supplier of organic mushroom extracts: Nammex. They have over 40 years of mushroom growing experience and were one of the first companies to bring organic functional mushroom extracts to North America.

Their ingredients go through rigorous quality control and are tested twice for heavy metals, agricultural chemicals and microbial contamination to ensure they meet all standards for dietary supplements of this nature. All of their extracts are made from certified organic mushrooms (fruiting bodies), organically grown or wildcrafted from deep within mountain regions of China.

Mushrooms used for dietary supplements are seldom grown in North America since they are too expensive. China is the leading supplier of mushrooms worldwide and supplies over 90% of the world’s mushrooms. 

It has a rich history of mushroom use as both food and medicine and is the birthplace of mushroom cultivation, with shiitake being farmed in the early 1200s. China is one of the only places in the world where you can get 100% organic mushroom (fruiting body) extracts that can be sold at an affordable price.

The products are identical. The only difference is how you want to consume them.

2 capsules is equivalent to roughly a 1/2 tsp of the mushroom powders.

In terms of potency and efficacy, both the capsules and powders are equally effective at delivering.

The capsules are great for travel, whereas the powder can be added to recipes or mixed in coffee, tea or bone broth.
