great value for money at less than 7p per day,a slightly lower potency for those wishing to \'top up\' their multi,a safe but relevant level for long term use ,convenient one-a-day source in soft veggie capsulesthis is the lowest strength vitamin e we offer, but don\'t be fooled in to thinking this is low potency. in fact the official nrv for vitamin e is 12mg, whereas this product delivers 168mg (or 250iu) per capsule. the reason for this huge difference is that the nrv\'s represent the minimum amount of a nutrient required for health, and is often less than the level recommended by nutritionists. certainly, many studies on vitamin e have been conducted at even higher levels and we are confident that vitamin e is very safe to take at levels that exceed the nrv.vitamin e is known to be one of the body\'s most important antioxidants and this product can be taken alongside any of our multis. the vitamin e is naturally sourced from vegetable oil.
