Vitamin D is the ‘sunshine vitamin’. This vital nutrient is produced naturally by our bodies in the summer months, but during the winter it can be difficult to get enough – especially for people over the age of 65. That’s why the NHS recommends that everyone take a vitamin D supplement from October to April.
VITAMIN D+ from FutureYou combines vitamin D with sunflower oil and comes in a liquid capsule to boost absorption, so we know that it is an effective way to boost your intake – but what results can you expect after just eight weeks? Our team decided to find out.
Our test results
Four members of the FutureYou team submitted a blood sample to an independent laboratory, to measure their vitamin D levels. After taking VITAMIN D+ for eight weeks, they took a second sample to provide a comparison.
Anyone with less than 50 nmol/L is considered to be vitamin D insufficient. The first test revealed that, despite exercising, eating a healthy diet and spending time outdoors, Tim, Sam and Lucy were all under or close to this crucial figure.
After eight weeks of taking Vitamin D+, they were all comfortably within the normal range – a fantastic result.
Our small experiment showed that supplements are a good way to address a lack of this important nutrient.
Why is vitamin D important to your health?
Dr Nicholas Shenker PhD FRCP, is a consultant rheumatologist at Addenbrooke’s Hospital in Cambridge and a member of the medical advisory board at Cambridge Nutraceuticals. He writes:
"Vitamin D enables mineralisation of newly formed bone, and plays an important role in muscle function. Sun exposure is crucial for its formation. In the summer, you should spend 10 minutes outside between 10am and 3pm on a clear day, three times a week, to generate enough. It is also found in fatty fish, fish oils, liver and eggs. In the UK, margarine, powdered milks and cereals are often fortified with vitamin D.
"If you are low in vitamin D, it can cause a condition known as osteomalacia in adults and rickets in children. Too little calcium in your bones will cause them to become ‘soft’ and more likely to fracture. Less severe vitamin D deficiency, sometimes termed vitamin D insufficiency, may still lead to secondary hyperparathyroidism, bone mineral loss, muscle weakness, and falls and fragility fractures in older people.
"There is good evidence that taking 25μg daily is safe, and it has been shown to increase life expectancy in an elderly population."
