Vitamin deficiencies
Vitamin deficiencies occur when the body lacks essential vitamins needed for proper physiological functioning, due to inadequate intake, poor absorption, or certain health conditions. Nutrition plays a real part in mood, cognitive function and physical energy, and deficiencies can show up as much in mental symptoms as physical ones.
- Persistent fatigue and low energy
- Weakened immunity, getting unwell more often
- Impaired concentration, forgetfulness or difficulty thinking clearly
- Low mood, anxiety or irritability alongside physical symptoms
- Physical symptoms such as hyper-acidity, constipation, frequent headaches or poor sleep
This is a guide, not a diagnosis. Only a qualified professional can assess.
- Nutritional assessment to understand dietary patterns and likely gaps
- Guidance on food-based ways to support vitamin intake, planned with your doctor
- Regular follow-up to track how dietary changes are working
- Coordination with your doctor where blood tests or medical treatment are needed
The care pathway
What each professional actually does here
Care for this concern is usually shared. Here is how each discipline contributes, so nothing feels like a black box.
A nutritionist assesses dietary patterns and everyday habits, then plans food-based strategies to support vitamin levels. Any specific correction is always assessed and planned together with your doctor.
