In the world of nutrition and preventative health, few nutrients have attracted as much attention as vitamin D in recent years and for good reason. Once primarily associated with bone health, we now know that vitamin D plays a much broader role, influencing everything from immune function to muscle strength, mood regulation and potentially even chronic disease risk. Emerging research continues to link low vitamin D levels with a range of health issues, including autoimmune conditions, infections, cardiovascular disease, and even certain cancers.¹ ²

Yet despite its importance, suboptimal levels of vitamin D or even outright deficiency remain surprisingly common and often go unnoticed. Many individuals may not realise they’re lacking it until symptoms such as fatigue, low mood, frequent infections or bone pain begin to emerge. The good news? Vitamin D is safe, inexpensive and easy to supplement. While the scientific literature continues to explore whether low vitamin D levels directly cause these issues or are simply associated with them as markers of poor health, teasing out causation from correlation can be complex. Nonetheless, given its favourable safety profile, low cost and potential benefits this is one supplement that many consider worth taking as a precautionary measure. It’s also the one I personally choose to take all year round.
