Our bodies produce vitamin D naturally when exposed to sunlight. Additionally, we also get the vitamin from certain foods and from supplements.

Nevertheless, large numbers of people in the UK are deficient in vitamin D. In a study released earlier this year, around 50 percent of Brits were found to be lacking sufficient levels of vitamin D.

While around one in six report taking a supplement, one pharmacist has issued a warning about potentially taking too much.

The dose of vitamin D supplements can vary. Though lower doses tend to be included in multivitamins, people can also supplement with higher doses in the forms of tablets, sprays and gummies, depending on their level of deficiency.

It is crucial, however, not to take too much.

Jana Abelovska, Superintendent Pharmacist at Click Pharmacy, explained to Surrey Live: “The best way to get vitamin D is through your diet, supported by supplements like tablets, capsules, gummies or sprays that you use directly into your mouth.
