Other Ingredients (6)
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.
MaltodextrinBinder
Spikes blood sugar faster than table sugar (glycemic index 85–105). Research links it to gut bacteria changes that may promote intestinal inflammation (Nickerson et al. 2015). Used as a cheap filler — adds nothing beneficial.
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Gum AcaciaBinder
Natural plant gum (acacia) used as a binder, stabilizer, and emulsifier in foods and supplements
HypromelloseCapsule
Plant-derived capsule material from cellulose
Mixed TocopherolsAntioxidant
Natural vitamin E used as preservative
How to Take It
Best taken in the morning
The Vitamin B12 in it is what pulls this toward the morning. Take it with a meal containing fat — the vitamin A in it absorbs poorly without one.
With a meal containing fat
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
Adults, as a dietary supplement, take one (1) capsule daily.
General guidance based on the ingredients, not a substitute for the label or your doctor.
