More Details

In Japanese, ‘Mai’ means dance and ‘Take’ means mushroom, thus ‘Dancing Mushroom’. Until about 1980 Maitake was only available from the wild.

Approximately 2000 years ago, Maitake was used in Traditional Chinese Medicine for improving the health of the spleen and stomach, calming nerves and treating haemorrhoids.

In more recent animal experiments and human clinical trials, Maitake was found to have promising anti-tumor and anti-viral properties. Other therapeutic uses of this mushroom include blood pressure regulation, control of diabetes, normalizing cholesterol levels, treatment of chronic fatigue syndrome (CFS), and anti-HIV activity.

Please click here to see our authorised 'Supplement Facts' label. And then use Google to look for additional details on Maitake's therapeutic potential - you will read about the 'D-Fraction®*', the 'MD-Fraction' and others.

The d-fraction is originally a term coined in the 1980s; it referred then to a purified -fractionated- beta-glucan, bonded with a protein; a so-called 'proteoglycan'. This particular fraction showed a lot of promise because of its anti-tumor potential.

Unfortunately, neither this product nor its successor, the md-fraction (a more pure version of the d-fraction, patented in 1997) is for sale in its undiluted pure form; the production costs are probably too high (it's a 200 : 1 extract) and the fractionating process is too complex for mass-production.

Although the manufacturers prefer to keep the details as vague as possible (marketing reasons), here are some -verifiable- facts:

  • Apart from being a research-term, 'D-Fraction®' is also a trademark*, registered in 1995. Products sold with the name 'D-Fraction®' contain, according to the label 'PD-Fraction®*' (which stands for 'Pre-D-Fraction'). It is unclear what this is.
  • The commercial supplement 'D-Fraction®' has been tested against another Maitake supplement, MaitakeGold 404®* (MTG), containing diluted version of the md-fraction. The test involved many immunological parameters. MTG scored significantly better in all tests.
  • MTG is standardised for ≥ 20% beta-glucans (though not on the label). Nothing else.
    The glucan/protein ratio is not revealed, although this would be an easy and cheap way to authenticate the product as being pure (the ratio should be between ± 2 : 1 (= d-fraction purity) all the way to 99 : 1 (= md-fraction purity) according to the patents).

 Based on the existing facts we feel confident ORIVeDA Grifolan® is at least equal to, if not more potent than the best of the current commercially available Maitake products. Apart from that, the value for money is much better.
