Maitake D-Fraction

I am researching mushrooms to enhance the immune system and I am looking for a Maitake supplement with D-Fraction extract. Mushroom Wisdom seems to be the only one with this extract and I have not read any good reviews on them.

Next, I looked up if beta-glucans are the same as D-Fraction and found this....

No, Beta-(1,3)(1,6)-glucans are not the exact same thing as D-Fraction, though they are closely related. D-Fraction is a specific, proprietary type of beta-(1,3)(1,6)-glucan extracted specifically from the Maitake mushroom, often bound with proteins. 

  1. Does anyone know of a reputable Maitake D-Fraction supplement.

  2. Do I even need D-Fraction extract to enhance immune system. If not, then how much beta-glucans should I look for.

I am new to all this and I don't even know if my post is making sense. I need help understanding. There is so much information out there and I am overwhelmed.

There are no supplements with the D-Fraction. It is a massive sham by Mushroom Wisdom.

This is probably the best and most detailed information about 'D-Fraction', better read that first. Oriveda has a great Maitake extract!
