How to Supplement with Real Food: Vitamin B12
Health Benefits of Vitamin B12
1. Red Blood Cell Production
Vitamin B12 is crucial for the formation of healthy red blood cells. Low B12 can lead to megaloblastic anemia, causing fatigue and weakness.
2. Brain & Nervous System Support
B12 maintains the health of nerve cells and supports brain function. Deficiency has been linked to memory problems, confusion, and even increased risk of dementia in older adults.
3. Energy Metabolism
While B12 doesn’t directly provide energy, it helps convert food into glucose—supporting energy production at the cellular level.
4. DNA Synthesis
It is essential for the proper synthesis and repair of DNA and RNA, making it vital for growth and development.
5. Heart Health
B12 helps lower homocysteine, an amino acid linked to increased cardiovascular risk when elevated.
