Frequently asked questions
Why compare cost per dose instead of price per bottle?
Bottles differ in serving size and strength. A cheaper bottle can cost more per day if you need two or three capsules to reach the same dose.
Which number should I enter for minerals?
Use the elemental amount, for example the magnesium or zinc content, not the weight of the whole compound such as magnesium glycinate.
