Experts have revealed the everyday symptoms which could show you have a vitamin or mineral deficiency, including cracked lips, headaches – and bad breath.
Persistent dandruff, itchy or dry skin, low mood and even stress could also be signs you need more of a certain vitamin or mineral in your diet.
Other issues which could point to a deficiency include thinning hair, a low libido, white spots on your nails and tiredness.
The findings come after a survey by Healthspan to launch its new magnesium range, found 44 per cent of Brits admit they have no idea about the different vitamins and minerals they should be consuming.
One in twenty, of the 2,000 adults polled, believe they need to be eating krill oil and vegetable oil for a healthy body, while some even said they thought kryptonite and kerosene are essential vitamins and minerals.
And almost six in ten admit they are clueless about the signs which could show they are suffering from a mineral deficiency.
Worryingly, almost half of Brits are unaware that taking medications, antibiotics and even drinking tea and coffee can all affect how you absorb vitamins and minerals.
Healthspan’s head of nutrition Rob Hobson said: “Many of these symptoms are things people put up with every day, thinking they are just par for the course.
“But often, they could be a sign that you are suffering a vitamin or mineral deficiency and simply eating foods which contain the item you are lacking could ease your symptoms.
“For example, a headache could be an indicator that you need more magnesium, vitamin B12 and B6 – something you can get from eating pumpkin seeds, prunes, banana or fortified soy milk.
“And even bad breath, while a possible sign of poor oral hygiene, could also be linked to your gut health and an iron deficiency.
“It’s important to bear in mind that your ability to absorb vitamins and minerals can also be affected by medications you are taking, such as antibiotics or the oral contraceptive pill as well as aspects of your diet such as whether you drink tea or coffee.”
