Low B12. Normal Blood Count?
Many people associate vitamin B12 deficiency with anaemia.
That’s understandable. B12 plays an important role in red blood cell production, and anaemia is one of the classic signs of deficiency.
What is less widely understood is that vitamin B12 also supports the nervous system.
In some individuals, neurological symptoms such as tingling, numbness, balance difficulties or brain fog may develop before obvious changes appear in routine blood count markers.
This is why healthcare professionals consider more than a single blood result when assessing B12 status. Symptoms, medical history, medications, dietary patterns and additional investigations may all contribute to the bigger picture.
If persistent symptoms are affecting your quality of life, they deserve proper assessment rather than being ignored or dismissed.
Understanding the signs of vitamin B12 deficiency can help people seek the right support and appropriate medical guidance.

Before The Positive Test: Folate Already Matters
Many women begin thinking about folate after seeing a positive pregnancy test.
What surprises many people is that some of the most important stages of early fetal development occur before a woman even knows she is pregnant.
The neural tube, which later develops into the brain, spinal cord and central nervous system, begins forming very early in pregnancy. This is why adequate folate intake before conception is so important.
Folate plays a key role in DNA synthesis, cell division and tissue growth. During early pregnancy these processes are occurring at an extraordinary rate as the foundations for healthy development are being established.
In the UK, women who could become pregnant are generally advised to take 400 micrograms of folic acid daily before conception and throughout the first trimester. Folate can also be obtained from foods such as leafy greens, lentils, chickpeas, beans, citrus fruits and fortified foods.
Pregnancy planning isn’t always possible, but understanding the importance of folate before conception can help support healthy fetal development during those crucial first weeks.
If you know someone who is planning a family, this information could be valuable for them.

Vitamin B12: The Message Carrier
Vitamin B12 does far more than support energy levels.
It plays a critical role in nervous system function, red blood cell production, DNA synthesis, methylation and cognitive health.
Low B12 status has been associated with fatigue, neurological symptoms, impaired cognition and megaloblastic anaemia.
Higher-risk groups include:
• Vegans
• Vegetarians
• Older adults
• Certain digestive conditions
• Long-term metformin users
One of the most fascinating aspects of B12 is that it works alongside folate in DNA synthesis and homocysteine metabolism, making both nutrients essential for healthy cellular function.
