A woman over 40 needs vitamin B12 like air! Here are the warning signs of deficiency.

The role of vitamin B12 has been studied by scientists around the world, and studies have shown that this vitamin also has many other health benefits.

Boosts energy levels: Vitamin B12 helps transport oxygen in the blood, nourishes cells, and converts carbohydrates from food into glucose, which our body uses for energy.
Prevents anemia: Because vitamin B12 helps produce red blood cells, the risk of this condition is lower. However, when vitamin B12 levels are low, the body does not have enough red blood cells to transport oxygen to vital organs. This causes symptoms such as fatigue and weakness.
Protects the heart from cardiovascular disease: Vitamin B12 lowers levels of homocysteine, a protein that damages arteries, increases the risk of heart attack, and can lead to atherosclerosis.
Protects vision: This benefit also plays a role in regulating homocysteine ​​levels in the blood. Vitamin B12 supplementation therefore helps reduce the risk of macular degeneration, a condition that affects central vision. An American study of 5,000 women over 40 who took vitamin B12 supplements for seven years showed a 34% reduction in the risk of developing any form of the disease, compared to the placebo group, which did not see any improvement.

Protects liver cells: Vitamin B12 protects the liver by preventing fat accumulation in this part of the body.
Promotes brain health: Vitamin B12 helps protect nerve cells and forms the myelin sheath that surrounds nerve cells and brain circuits, helping transmit nerve impulses throughout the body.
Reduces the risk of birth defects: Adequate vitamin B12 levels are essential for a healthy pregnancy. Studies have shown that the fetal nervous system and brain require adequate amounts of vitamin B12 from the mother for proper development. Vitamin B12 deficiency in the early months of pregnancy can increase the risk of birth defects, such as neural tube defects. Furthermore, according to Irish researchers, maternal vitamin B12 deficiency increases the risk of premature birth or miscarriage.
