How it's calculated
Price per 100 мг — the cost of 100 мг of the substance in a single product, calculated based on the ingredients listed on the label. The “Form” column indicates how well the substance’s form is absorbed. In the “By Price (Adjusted for Form)” sort, the price is divided by a form coefficient (ranging from 0.5 to 1): the poorer the form, the higher the final cost; “Best Forms” lists only the optimal forms. The table includes products with a listed price; discontinued products are excluded.
