I have a long term infection and weakened immune system. Since I've been taking this product my immune system has been much stronger. I've even been around many sick people but haven't got anything. I take 1/4 tsp every day either in hot choc, coffee, or mixed with other shrooms in milk and hot water. I woke up one morning feeling like I was getting something so I took it 3 times that day and was fine the next day. I quite like the taste, it has a malty smell. I can't be without it.
