Doctor's Best High Absorption Magnesium, 200mg

Doctor's Best takes a science-catalogue approach to its labelling, and its High Absorption Magnesium is typical of the house style: magnesium at 200mg, in tablet form, offered as 120-tablet and 240-tablet bottles.

The two counts split neatly between a standard bottle and a double-size one for longer stretches between orders. As with the rest of the brand's single-ingredient range, there is nothing to prepare — tablets are taken as the label directs. Both sizes are listed in our Vitamins and Health category.

• Dose: 200mg magnesium per serving
• Sizes: 120 and 240 tablets
• Brand: Doctor's Best
