Fatigue isn’t simply about feeling tired. It can be a persistent drain on your motivation, focus, and overall well-being, affecting every aspect of your life. The trick is knowing that if you’re constantly running on empty despite getting enough sleep and managing your stress, your body may be missing something vital: essential nutrients like vitamin D and vitamin B12.

These essential vitamins play a central role in energy production, mood regulation, and immune function, making them a major cornerstone of optimal health.

Why Are You Always Tired?

Many people dismiss fatigue as a result of a busy lifestyle, but in reality, low levels of vitamin D and B12 are some of the most common (and often overlooked) causes of fatigue in adults.

These deficiencies are more widespread than most realise:

Vitamin D deficiency is prevalent in up to 20% of UK adults, especially in the winter months, due to limited sunlight.
Vitamin B12 deficiency affects around 6% of adults under 60, and up to 20% of those over 60, according to NHS data.

When these levels drop, the effects can be profound: chronic fatigue, poor concentration, muscle weakness, low mood, and even immune dysfunction - an unfortunate combination for anyone, but particularly problematic for the modern UK city resident.

The Role of Vitamin D and B12 in Energy Production

Both vitamin D and B12 are essential for maintaining steady energy levels and supporting your body’s physical and mental performance. Vitamin D, often referred to as the "sunshine vitamin," plays a key role in mitochondrial function - the process your cells use to produce energy. When vitamin D levels are optimal, your cells are better equipped to generate the energy your body needs.

It’s also important to note that Vitamin D helps regulate the amount of calcium and phosphate in the body, which are needed to keep bones, teeth and muscles healthy. It also supports the immune system and has been linked to improved mood and emotional resilience. On the other hand, vitamin B12 is crucial for the formation of red blood cells, which are responsible for transporting oxygen throughout the body. A good oxygen supply means your muscles and brain can function at full capacity. B12 also supports the nervous system and helps to clear brain fog, enhance focus, and reduce the mental fatigue that often accompanies low energy.

When either of these vitamins is depleted, your body struggles to function efficiently. Energy levels dip, cognitive clarity fades, and even the simplest tasks can feel exhausting. And unfortunately, no amount of caffeine or extra sleep can compensate for a true nutritional deficiency.

So when you boost your energy with our IV infusions, you’re actually boosting everything you need in your body for a healthy, active lifestyle.

Why Choose IV Drips Over Oral Supplements?

While oral supplements can be beneficial, they often take longer to be absorbed and may be less effective in individuals with digestive issues or poor nutrient absorption. That’s where IV vitamin therapy makes all the difference.

At Body Brilliant, our Vitamin D and B12 IV drips deliver nutrients directly into your bloodstream, bypassing the digestive system for maximum absorption and rapid results. Many of our clients report feeling more energised, focused, and mentally sharp within hours of treatment.
