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.
Microcrystalline CelluloseBinder
Plant-derived cellulose used as a binder and filler in supplements
How to Take It
Best taken in the morning
The Iron in it is what pulls this toward the morning. Vitamin B6 is easier on the stomach taken with food.
With food
Iron does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Keep it away from coffee, tea and dairy
Space it a couple of hours from Calcium, Zinc, Magnesium, Manganese and Green Tea Leaf Extract
On the label
