"Mushrooms are some of the strongest natural immune modulators known to man, and maitake is my favorite mushroom. It contains beta-glucans whose unique molecular structure allows them bind to and activate key immune cells, like NK (Natural Killer) lymphocytes. However, most mushroom products on the market today use processing methods like grinding, which can easily damage the structure of the beta-glucan. This product uses traditional hot-water extraction, the only method proven to not damage the shape and structure of the beta-glucans. I know its a bit pricey, but I highly recommend it for people with weakened or challenged immune systems. I take this in the wintertime and whenever I need a little extra immune support." - Jiying

There are no references for Maitake in the Chinese herbal texts. However, Japanese herbalists have long used Maitake tea as an adaptogen, to help balance the various systems and functions of the body in times of stress.
Most importantly, the Maitake polysaccharides have been found to balance, stimulate and support the immune system, the bodies’ internal defense system against external invaders. These were the properties that made Maitake valuable in Japanese herbalism, and it was this traditional use that caught the attention of modern researchers.*


MaitakeGold 404 is a potent Maitake mushroom extract developed by Dr. Hiroaki Nanba, PhD., the inventor of Maitake nutraceuticals. MaitakeGold represents such a significant improvement in Maitake formulations that it was granted a U.S. Patent (U.S. Patent # 5,854,404), and is the only Maitake supplement that carries Dr. Nanba’s personal endorsement.

Maitake is the only medicinal mushroom that can be hot water extracted and sold in a liquid form and still provide an effective dose for immune support. MaitakeGold 404 is a hot water extract preserved in glycerin, offering an alcohol free supplement for immune support.*

The other liquid mushroom supplements on the market are preserved in alcohol and are called tinctures, also known as “cold water extracts”. These products contain very low levels of active compounds, including the key immuno-modulating compounds, the polysaccharides, that define a mushroom as medicinal. This is because tinctures are processed at room temperature, far below the temperatures required for hot water extraction. Tincturing works for plants but not mushrooms or mushroom mycelium.

Medicinal mushrooms are prepared as hot water extracts in 100% of the herbal and scientific references for a reason, it is the only preparation method capable of releasing the active compounds from the indigestible cell walls of mushrooms and mushroom mycelium and into a bioavailable form.


In the early 1980s, Dr. Hiroaki Nanba, a professor of microbiology and an expert mycologist at Kobe Pharmaceutical University, was intensively studying the medicinal properties of various mushrooms. During this time much of his attention was devoted to the popular Shiitake mushroom. However, his research showed him that Maitake had a unique molecular structure that exhibited greater immune activating power than the other medicinal mushroom extracts he had been working with.*

He also discovered that the immune benefits Maitake provided worked well when the extract was taken orally. The highly concentrated beta glucan extract from Shiitake, known as Lentinan, only worked when injected.*
In 1984, Dr. Nanba isolated an important Maitake fraction (or specialized component) that stimulated macrophages. According to the studies this Maitake fraction also had the ability to directly enhance the activity of Natural Killer (NK) cells and to change NK precursor cells into activated NK cells.*
Using a special extraction method these Maitake fractions were concentrated to produce a standardized liquid polysaccharide extract containing beta-1,6 1,3 glucan, now sold under the brand name MaitakeGold 404. Later in his research, Dr. Nanba patented the extraction process for MaitakeGold 404®.
