BAD news for revellers taking a fizzy vitamin C tablet to ease their hangover – as they have high levels of salt that could lead to worse ailments than hangovers.
Popular fizzy vitamin C tablets taken by millions of Britons contain more salt than two bags of crisps in a single dose, new research shows.
The fruity flavoured pills, which dissolve in water, are the most popular way to consume the supplement – and are popular after a night out to boost vitamin levels.
But those sold by many best-selling brands can contain as much salt as of two bags of Walker’s Ready Salted crisps.
The 1g of salt equates to 17 per cent of a person’s recommended upper daily limit per tablet.
Salt is a compound made up of sodium and chlorine – and sodium bicarbonate has traditionally been used to help these tablets dissolve in water, producing the ‘fizzing’ effect.
But sodium is a well-known contributor to high blood pressure, a condition affecting around 30 per cent of the UK’s population, according to the NHS.
During the research, the salt equivalent content of popular effervescent tablets, including Berroca and those sold by Boots, was examined by scientists
Of the seven products tested, Waitrose blackcurrant flavoured vitamin C effervescent had the highest salt content, equating to more than two bags of crisps.
In fact, both blackcurrant varieties (Boots, Waitrose) contained more salt (sodium) than standard orange flavoured tablets.
Adults should consume no more 6g salt a day. More than this raises their risk of high blood pressure, heart disease and stroke.
Dr Sarah Brewer, nutritional expert, said: “Heart problems are a common side effect in a diet too high in salt.”
“Too much salt will raise your blood pressure, which can lead to heart disease, stroke and heart attack.
“Research published in the American Journal of Clinical Nutrition found it takes just half an hour for one salty meal to significantly impair the arteries’ ability to pump blood around the body.”
The research in an accredited lab was commissioned by supplements firm Healthspan, who have produced their own low sodium effervescent vitamin C tablet.
