Coffee and Vitamin Pills

In these health-conscious times, millions of wash down a vitamin pill as part of their breakfast routine. But it seems you may be wasting your time. Researchers claim swallowing vitamin supplements with tea or coffee can wipe out all the good they do. The heat in the drinks can dramatically reduce the effects of tablets, and even kill the ‘friendly’ bacteria in probiotics.

In a study conducted by the University of East Anglia, England, it was found that hot drinks and food such as porridge inhibit the absorption of iron by up to 73 per cent. Around 46 per cent of British adults take daily vitamin supplements, and 70 per cent of those who do take them with breakfast. Now experts suggest waiting at least an hour before consuming hot food or drink after taking tablets. Coffee can reduce iron absorption by up to 80 per cent if drunk within an hour of a meal. Very hot drinks can also inactivate some vitamins, and kill live probiotic bacteria. To ensure beneficial bacteria survive, a professor of food microbiology at the University of Reading, advises washing down supplements with water or milk. Breakfast is still the best time to take pills, as the gut has rested overnight and is therefore more receptive.

Researchers at the University of Turku, Finland, emphasised that ‘It’s important to begin taking probiotics from the moment you start antibiotics and continue for a few weeks after finishing the course.’
