Discover the importance of vitamin B12 in nutrition, its sources, health benefits, signs of deficiency, and recommended daily intake.
Vitamin B12, also known as cobalamin, plays a crucial role in maintaining the health of nerve cells and in the production of DNA. It is essential for the formation of red blood cells and proper brain function.
Vitamin B12 is primarily found in animal products such as meat, fish, eggs, and dairy. For vegetarians and vegans, fortified foods or supplements are recommended to meet their daily requirements.
Having adequate levels of vitamin B12 can help prevent anemia, support a healthy pregnancy, and reduce the risk of neurodegenerative diseases.
A deficiency in vitamin B12 can lead to symptoms such as fatigue, weakness, constipation, loss of appetite, and neurological issues. It is important to address a deficiency through dietary changes or supplementation.
The recommended daily intake of vitamin B12 varies by age and life stage. Adults typically need 2.4 micrograms per day, with higher amounts recommended for pregnant and breastfeeding women.
