Oriveda's focus is on selling well-researched medicinal mushroom extracts of superior quality.

As a business we are focused on providing our customers with the best possible products, value-for-money and service. We are serving customers in over 85 countries.

Our business is based on common sense and pragmatism. We feel that every claim of quality should be backed up with hard facts.

All our products are tested by independent objective laboratories, not just for safety but in particular for active ingredients. You don't have to take our word for it when we claim premium quality - you can verify it. We share our test reports with our customers.

For some bullet-points just click here.

• Therapeutically speaking, ORIVeDA extracts are the most powerful extracts available worldwide, with guaranteed levels of the most important bioactive components and the highest bioavailability possible. And this is not just a marketing statement.

Our authorized supplement facts labels and Google make it easy to compare our products with others. As said, our Certificates of Analysis from independent third party laboratories are available here.

• Since we started as a business we have always emphasized the use of extracts, being the only reliable way to accomplish therapeutic effects.

Already in 2012 we started specifying beta-glucans (the main active ingredient of most medicinal mushrooms) on our supplement fact labels. This was a time when 95 % of mushroom supplements had zero specifications (not being extracted) and the rest mentioned 'polysaccharides' at best, a broad term covering a lot of non-bioactive compounds, in the core unsuitable as a quality marker. Currently beta-glucans are widely accepted as a quality marker, using an AOAC-validated test method.

• We are the first ones specifiying cordycepin as a quality marker for Cordyceps and the first and only ones to specify the NGF-promoting compounds for which Lion's Mane is known - the terpenes. In short, we have set and pointed out quality standards since we started. This approach makes it easy for consumers to choose the right stuff and they're less likely to be deceived by marketing tricks. Make sure to check our FAQ for additional details.

• The value-for-money you get with our products is excellent. Not only are our prices often lower than others, but the level of bioavailable active ingredients in our extracts is also much higher, in some instances over three times higher than the best of the rest. So, instead of spending $ 90 on “product X” you only have to spend $ 30 on our product for the same therapeutic potential.
And on top of that, as said before, we guarantee the bioavailability of the bioactives; your body can absorb and digest them 100%, so the therapeutic potential is maximal. And all these claims can be verified - objective third party test results are available here.

• In SE-Asia medicinal mushrooms have been used for many centuries. These countries therefore contain probably the best-informed and most critical consumers. We are proud to be able to claim that we are currently the only Western company selling mushroom extracts on a large scale to this region.
• A lot of the research on which our products' reputation is built is available and can be downloaded for free from the resources-section of our site.

• We ship to almost all countries in the world, except warzones.With only a few exceptions, shipping is free for website orders, worldwide. We usually ship orders the next day.

• We offer maximum personal service: we are online 7 days a week and your questions will be answered in great detail. Those questions are important: they help us develop new ideas and products. Keep them coming!

• Our newsletter (2 - 3 times p/year) is offering more than just updates and marketing. We often include complete monographs related to our product-line and include discounts for subscribers. Register today!

About Maitake

Oriveda Maitake

Maitake's therapeutic potential has been researched intensively since the late 1970s. It was the hype of the day during the 1990's, a reputation based on promising research results. Below is a list of the main targets of this research; due to legal restrictions we can't give more details. Take notice: this list should not be interpreted as a list of medical claims !

Our research section has several interesting publications, free to download.

Before you start using Google, read the other entry on this page: 'Why ORIVeDA's Grifolan ?' or, even better, read this extensive background article.

  • • Maitake's anti-viral and anti-tumor potential (in vivo, in vitro and clinical tests)
  • • Maitake's cardiovascular effects
  • • The effect on the Chronic fatigue syndrome (CFS)
  • • General balancing of the immune system. Maitake is considered 'King of Immunity'
  • • The effect on diabetes. Maitake contains a natural alpha glucosidase inhibitor, which lowers blood sugar
  • • Blood pressure regulation
  • • Anti-cancer adjuvant - using purified Maitake extracts together with regular treatment seemed to improve the effects considerably.

  • • Side effects and safety

    Because Maitake has immune-balancing properties, it should not be used together with immune-suppressants, like those prescribed after a transplant.
    The blood sugar lowering effects can cause temporary fatigue in those that are highly susceptible. In general these people are also very susceptible to e.g. caffeine and alcohol, or are diabetics. Taking the extract together with a sugar containing liquid can neutralise this effect.

    In general Maitake is safe to use, even in high doses and for extended periods of time.

ORIVeDA's Maitake Grifolan®

Oriveda Maitake

First of all, click here to see our authorized '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:

more details...

  • 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 (according to that same test rapport and a follow-up) a 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).
  •  
  • MTG is sold only in liquid form; 1 gram of extract dissolved in 30 ml of liquid. The recommended daily dosage is 8 - 16 drops daily, which equals 19 - 77 mg MTG.
    The optimal dosage of this extract is, according to independent research (a clinical trial), 7 mg/kg bodyweight/day (e.g. a 60 kg person should take ± 420mg daily), which is significantly more.
  •  
  • ORIVeDA's Grifolan® is standarised for ≥ 35 % beta-glucans, has a glucan/protein ratio of 2.5 : 1 (equals the original d-fraction) and can deliver the recommended daily dosage for optimal immunological effect easily. Because the extract used in the research was more pure than any commercially available product, the dosage should be adjusted accordingly: we recommend at least 4 - 8 capsules per day (each with ≥ 150 mg beta-glucans) if maximum therapeutic potential is needed. (The standard dose for normal immune support is 2 capsules daily.)

Summarizing: 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.
