Dr. Michael Murray recommends only MaitakeGold 404, the authentic patented maitake mushroom formula of powerful immune-enhancing compounds developed by Dr. Hiroaki Nanba of Japan.

The "Certified Bioactivity" seal guarantees that each batch of MaitakeGold 404 is proven and certified to activate immune cellular response.

All Natural Factors products are manufactured in accordance with the Government of Canada's Good Manufacturing Practices (GMP), among the highest standards in the world.

Suggested Use

For daily immune support, take 1 capsule (15 mg) per day. For advanced immune support take 1 mg for every 2.2 pounds of body weight or as directed by a health professional.

Calculate: Body weight divided by 2.2, multiplied by 1 mg = dosage. e.g. 140 lb. would equal 4 capsules per day. Best if taken on an empty stomach.

Rice powder, gelatin capsule (gelatin, purified water), magnesium stearate (vegetable grade).

Wonderful Product

Posted by Reviewer1638725 on Feb 05, 2010

My mother is a cancer patient who has been taking these for seven years to bolster her immunity; we think they are a wonderful product. These were used in a Sloan Kettering trial on breast cancer patients, and it was through a doctor at the Integrative Center there that we found out about these.

I didn't buy the Gold 404 expecting to see any results. I bought it because I have cancer in my family, and I want to attack a cancer cell before it becomes an issue. I have seen the results of Maitake Gold 404 and I am impressed. I take it as a prophylactic.

Tool For Beating Cancer!

Posted by Reviewer1994791 on Feb 25, 2009

My husband used this during Chemo Treatments. He didn't have the side effects he would have had without it and six weeks later he is now cancer free! NO MORE LYMPHOMA! He continues to use a lesser amount to keep him cancer free! My mom is also using this while on chemo for a brain tumor. She is also seeing the results and won't go without it!
