Overview
['Life Extension positions this as a dual action mineral capsule, combining 99 mg of potassium with 250 mg of magnesium in an extend release form, in a 100 count vegetarian capsule bottle. The unflavored capsule is labeled gluten free and non-GMO, which broadens who can reasonably consider it.', 'The extend release magnesium angle is the main differentiator the manufacturer highlights, aimed at buyers who want the two minerals released over a longer window rather than all at once. At close to 20 dollars for 100 capsules, it sits at a mid range price point for a combined mineral formula from a well known supplement brand.', 'This listing has drawn a large amount of feedback, with a 4.6 rating from 6,600 reviews, even though the reported 400 units bought in the past month is more modest. Because this combines two minerals with a specific release profile, it is worth discussing with a healthcare professional before adding it, especially alongside other supplements.']
