Rice FlourFiller
Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports). Rice accumulates arsenic from soil at higher rates than other grains. Used as a cheap filler — adds nothing beneficial.

The Vitamin B12 in it is what pulls this toward the morning. Take it with a meal containing fat — the vitamins D and E in it absorb poorly without one.
