10. Vitamin B12
Vitamin B12 declines in the body as a person ages. Lack of this vitamin can lead to mobility issues and problems in cognitive functions later in life.
Alas, this vitamin is found only in animal foods. Vegetarians can get their supply from dairy foods. However, vegans may find it difficult to get this vitamin.
Vitamin B12 is found in ample amounts in meat, poultry, eggs, and dairy.
You must take supplements in case you don’t eat the above foods.
