Good product. Has an excellent mix of mushrooms and at good doses. It's also reasonably priced given the ingredients and dosage. The capsule is rather large and was a little difficult for me to swallow. (That's my only complaint.) there is a slight mushroom-y taste, so keep that in mind.
The reputable company, Nature’s Plus, offers an immune formula that includes 7 mushrooms. Two capsules gives 145mg each of important medicinal mushrooms like reshi, shiitake and cordyceps. Press like if this review helped. Thanks.
