These are wonderful. I've been making natto with these spores since last summer by following emmymadeinjapan's tutorial on Youtube. I found that my digestion and energy improved immensely with the addition of natto into my diet. When I transitioned to a plant based diet four months ago natto was incredibly helpful in maintaining my energy levels. I will be reordering.
