About $0.08 per serving across 42 tracked selenium products, ranging from $0.05 for the best deals to $0.10 for premium options.
Is the cheapest Selenium the best one to buy?+
Not always. The cheapest is sometimes cheaper because of the form — magnesium oxide costs less than glycinate per gram but absorbs at a fraction of the rate. Weigh cost-per-dose against form bioavailability and third-party testing, not price alone.
