Vitamin D is essential for strong bones and teeth, healthy muscles and many other benefits to keep you in tip-top health. We can get it from sunny summer days and some foods. It’s easy to become deficient, so we need to take supplements in the darker months or depending on our ethnicity. Let’s take you through why it’s important, and how you can boost levels.

Everyone goes through phases of feeling unmotivated or lacking in energy – it can be part of life’s normal ups and downs. But if fatigue and lethargy persist without obvious cause – you're not working long stressful hours or have a new baby – then perhaps you need to consider an underlying cause.

As the days get shorter and the temperature cools, it can be tempting to curl up on the sofa with some comfort food and a binge-worthy box set. But we are not naturally hibernating animals, so it’s important to understand why your energy levels may dip while your appetite increases, and address it with healthy choices. The doctors at Healthwords will always encourage a healthy balanced diet over and above taking supplements, and the more colourful and varied your meals, the more nourishing nutrients you are getting. But there are times that supplements may be helpful or even vital. There is less choice of fresh foods over winter, and less sunshine to naturally make vitamin D, plus fighting off colds and flu means our immunity needs to be in tip-top condition. Let's talk you through the challenges of winter and how to counter them to keep you healthy in mind and body.

There are many possible symptoms of vitamin D deficiency, although it is also possible to have no symptoms at all. Here in this article, Healthwords will walk you through both what Vitamin D does, why it is so important and what the symptoms of vitamin D deficiency are so that you can be on the lookout.
