Run down? Energy levels low? Many of us are already choosing to supplement our dietary plans with vitamins D and B50 complex. Here we explain why…

At this time of year, it often feels like a long slog until summer. The dreary weather makes our bodies more susceptible to colds and flu and we could all do with a pick me up to bolster our immunity and combat the dreaded SAD.


Vitamin D (also known as vitamin D3) can improve our mental health, reduce fatigue and charge up our energy levels. Vitamin D is made by our bodies when we are exposed to sunlight so deprivation in the winter months can lead to a condition known as Seasonal Affective Disorder.

Research has shown that our vitamin D receptors are in the same area of the brain associated with depression.  Studies have shown a link between vitamin D deficiency and depression, with research finding that those participants with depression also had low levels of vitamin D. The same analysis found that, statistically, people with low vitamin D were much more prone to depression.



Vitamin D plays a key role in boosting the immune system and research has shown that supplementation with vitamin D can significantly prevent some acute respiratory tract infections.



Playing an important part in the regulation of calcium and phosphorus levels in the blood, vitamin D is essential to keep bones healthy and strong.  



Our B vitamins work in the ‘engine room’ of our bodies, helping convert our food into fuel by breaking down fats and carbs and allowing us to stay energized throughout the day. They also play an important part in our body’s enzyme systems, regulating metabolism and our endocrine system.

Significantly, many of these water-soluble B vits can’t be absorbed and stored in our body and should be replaced every day through diet or supplementation. Many of us choose to supplement with vitamin B50 complex for this very reason. A vitamin D complex includes:

Thiamine (B1) – for a healthy heart and nervous system.

Riboflavin (B2) – the ‘food into fuel’ converter to maintain energy levels.

Vitamin B6 – another energy convertor which maintains a healthy metabolism, nerve function, liver function as well as skin and eye health.

Vitamin B12 – maintains a healthy heart and nervous system and is also essential for adrenal fatigue, multiple metabolic functions and hormone balance.

Folic acid – vital in helping the body to maintain and produce new cells.

Pantothenic acid (B5) – helps the body to create red blood cells.   


Lifestyle, age and limited sun exposure can all play a part in how deficient in vitamin D or B vitamins you may be. Take our quick and easy lifestyle survey here to find out what may be missing from your day-to-day nutrients.
