Value Sizes
Value Sizes are the larger counts of the formulas people take every day - the 120 count zinc carnosine, the 90 count aged garlic, the 60 count magnesium. More servings per bottle means a lower cost per serving and fewer reorders.
The count is printed in each listing title, and the product page states the days of supply at the labelled serving. If you are trying a formula for the first time, the smaller count is usually the better start.
