I don't know how close they compare to the fruit, but commercial supplements use mycelated rice to make pills and there are thousands of reviews out there saying the pills help people.

There is some info here. Conclusion as I understand it is that it is not clear which is better (mycelium or fruit), but both have medicinal compounds.

If you have a colonized jar (and don't want to colonize bags), you can try to open the jar lid and place it in a mushroom monotub that has glass cup of water in it (source of humidity). It is very likely that you will get a delicious fruit to pop out of the top of the jar (I think).
