Other Ingredients (3)
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.
LeucineFlow Aid
Branched-chain amino acid used as a processing aid
Microcrystalline CelluloseBinder
Plant-derived cellulose used as a binder and filler in supplements
How to Take It
Best taken in the morning
Many people prefer B-vitamins earlier in the day; take with food to avoid nausea.
With food
ALA 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.
On the label
Take 3 capsules daily, preferably with meals, or as directed by a your health practitioner. May take in divided doses.
General guidance based on the ingredients, not a substitute for the label or your doctor.
