A recent survey reveals that the vast majority of parents – 92 per cent – have bought vitamins for their children over the past year. This total includes multivitamins from Boots, £260; probiotics sachets, £480; £75-ish on the vitamin D mouth sprays; around £100 spent on manuka (what are they feeding those bees, rare orchids?). The real wallet-killer is the omega-3, in the form of jelly sweets shaped like fish. I pop several capsules and pills, from high quality omega-3 to a multivitamin, to magnesium glycinate in the evening before bed. Added to the mix is a potion including thyme and apple cider vinegar, a fizzy vitamin C drink and a vitamin D spray.
