I had no idea that mushrooms were a good source of vitamin D until I watched Louise Gagne’s vitamin D presentation. In her discussion she specifically mentions chanterelle mushrooms. I then found this vitamin D study involving white button mushrooms. Just so you know, it’s the ergocalciferol (D2) that is found found in mushrooms, which in Dr Holick opinion can be about 50% less effective than the Colcalciferal (D3). That being said, certainly sounds like a decent way for those with lactose intolerance or vegetarians to get vitamin D. (Personally I can’t stand mushrooms so I’ll be sticking with my Colcalciferal (D3) supplements)
