Hidden Health Crisis: Tiredness Linked to Vitamin Deficiencies
4 Jan
Summary
- Tiredness and brain fog can signal B12, iron, or folate deficiencies.
- Vitamin B12 is crucial for nerve protection and efficient brain signaling.
- UK plans to fortify white flour with folic acid by end of 2026.

Persistent fatigue, cognitive fog, and tingling sensations may indicate underlying nutrient deficiencies rather than mere stress. Vitamins B12, iron, and folate are critical for brain function, nerve health, and oxygen transport, and their depletion can significantly impair daily activities.
Specifically, vitamin B12 is vital for nerve protection and efficient brain signaling; low levels can lead to memory issues and balance problems, increasing fall risks in older adults. Iron deficiency hinders oxygen delivery, first affecting high-energy tissues like the brain, causing light-headedness. Folate supports cell growth and red blood cell production, with declining levels particularly noted among teenagers.
To address these issues, the UK government is set to fortify white flour with folic acid by the end of 2026, targeting common bread and baked goods. While dietary changes can help correct folate deficiencies, iron often requires supplements due to absorption complexities. Vitamin B12 needs may be met through supplements or injections, especially for vegans, older adults, or those on specific medications. Prompt diagnosis via blood tests and appropriate intervention can lead to significant recovery within weeks.
