8 ounces. our 27 puond dog gets two scoops per day (scoop comes i n jar) and it lasts about one month.

How long does this last?

It depends on the size of your dog or cat. My dog is 93 pounds. I give him just a little under a Tbsp. a day on his dry kibble mixed with water. One jar will last me about one month. This is the largest serving size at 2 1/2 scoops. If you dog is smaller it will last longer.

Why does this product have warning: california’s proposition 65 ??

Mushroom Complex contains naturally-occurring lead that is found in low amounts in some of the plant-based ingredients we use in the supplement. Lead is naturally present in the soil, and as such, it can accumulate in certain plants. Dr. Mercola is aware of this but feels that the benefits that can be gained from taking the product far outweigh any risk associated with the minute amounts of lead in the product.

Why are so many different mushrooms used in this one?

I believe that this combination gives the advanced immune support that is needed for an anti-cancer regimen. The Reishi especially is known in Japan to actually reduce the size of cancer tumors. I'm using this on my dog who has had adrenal carcinoma and is doing very well.
