Vitamin B12 is essential to the body’s nervous system and crucial for a healthy brain. It plays a vital role in the production of white blood cells which are necessary for immune system function.

Not getting enough B12 in your diet can lead to anemia that causes weakness and fatigue. Some people are at a greater risk than others for this deficiency based on the FUT2 gene. The FUT2 gene is involved in vitamin B12 absorption and transportation between cells.

Food sources that may be beneficial to individuals with a vitamin B12 deficiency are:

• Meat
• Fish
• Poultry
• Eggs
• Milk
• Fortified cereals

Test your genomic profile to see if you’re at risk for low vitamin B12.
