365 by Whole Foods Market

Our verdict

365 by Whole Foods Market works out to $0.07 per serving of potassium, at 99mg per serving in tablet form. That puts it around the median of the 35 potassium products we can price per dose, where the typical serving costs $0.06, a Value Index of 0.8 where the median product is 1.0. One container lasts 250 days at the label dose of 1 serving a day, about $2.04 a month. We could not verify a third-party certification for 365 by Whole Foods Market in a public registry.
