Vitamin B12: Why You Should Take It

Red blood cell production: B12 plays a crucial role in the formation of red blood cells, which carry oxygen throughout your body. Deficiency can lead to anemia, a condition characterized by fatigue, weakness, and shortness of breath.

2. Nerve function: B12 is essential for maintaining the health of your nervous system and brain. Deficiency can cause symptoms like tingling, numbness, and even dementia in severe cases.

3. DNA synthesis: B12 is involved in the production of DNA, the genetic material in your cells. This ensures healthy cell replication and function.

4. Mood and energy levels: B12 contributes to the production of certain neurotransmitters, which are chemicals that regulate mood and energy. Deficiency can contribute to fatigue, depression, and low mood.

5. Heart health: Some studies suggest B12 may help reduce homocysteine levels, a compound linked to an increased risk of heart disease. However, more research is needed to confirm this definitively.

Who needs B12?

Everyone needs B12, but certain groups are at higher risk of deficiency, including:

  • Vegetarians and vegans who don’t supplement
  • Older adults
  • People with digestive disorders that affect B12 absorption
  • Individuals who have undergone weight loss surgery

How to get enough B12:

  • Animal sources: B12 is naturally found in animal products like meat, poultry, fish, eggs, and dairy.
  • Fortified foods: Some breakfast cereals, plant-based milks, and nutritional yeast are fortified with B12.
