Take one tablet twice a day, preferably with a meal. The tablets are not intended to be crushed, split, or chewed, so take each tablet whole and follow the stated schedule.
The package is a two-pack containing 300 tablets total. The tablets are free from gluten, preservatives, yeast, and artificial flavors; they do contain soy. Major Pharmaceuticals says it follows strict regulatory compliance standards in its formulation process.
