Vitamin deficiency test at Cardiff and Vale Hospitals

What is a vitamin deficiency?

A varied diet usually includes all vitamins you need. However, in developed countries vitamin deficiency can occur in:

• people with alcohol and drug dependency
• the elderly
• those with a poor diet
• vegans - vitamin D and B12 may be lacking in vegans, who eat no animal products
• people with gut disorders
• people who don't get enough sunlight. 

How do you know if you have a vitamin deficiency?

Common symptoms of vitamin deficiency include:

• shortness of breath
• tiredness
• fast heart rate
• brittle hair and nails
• hair loss
• mouth ulcers and cracks around the mouth

Vitamin supplements

Vitamin supplements should not be needed in a healthy person who has a varied diet and they can be harmful if taken in excess.

The therapeutic value of vitamins as a treatment, for example vitamin C in cold prevention, vitamin B6 for pre-menstrual tension (PMT) and vitamin E to improve well-being, is unproven . 

However, vitamins are used to treat some conditions that are not due to a deficiency such as vitamin D for the treatment of osteoporosis (combined with other treatment) and vitamin A for acne.
