Health experts have issued a warning about the potential side effects of incorrectly taking vitamin D supplements, a common practice during the UK's darker months. While vitamin D is essential for bone and muscle health, overconsumption can lead to toxicity.
The NHS recommends a daily 10 microgram supplement from October to March, as sunlight is insufficient for vitamin D synthesis. However, Dr Kathryn Basford from Asda Online Doctor cautioned that taking more than the recommended amount can cause fat-soluble vitamins to build up in the body, leading to toxic effects.
Nutritionist Katherine Elyse Blake noted that many people assume 'more is always better,' but vitamin D requirements vary based on factors like sun exposure, skin tone, and body weight. She also warned that taking vitamin D late in the day may interfere with sleep due to its effect on melatonin production.
Consultant dermatologist Dr Aiza Jamil explained that incorrect vitamin D intake can impair skin barrier function, leading to dryness, dermatitis, and uneven skin tone. She emphasised that the skin is the primary site of vitamin D synthesis and relies on proper levels for health.
Experts advise choosing supplements wisely: tablets offer higher doses but slower absorption, sprays provide faster uptake but may contain additives, and gummies are palatable but often lower in nutrients. It is crucial to consult a doctor to determine the appropriate dose.
