One of the most commonly deficient nutrients is vitamin B12, especially among vegans. Vitamin B12 is an essential nutrient that the body needs to synthesize DNA, create energy, and maintain central nervous system function, according to the US health website Healthline .
Long-term vitamin B12 deficiency can cause joints to become inflamed and painful, leading to joint swelling and limited mobility.
However, the ability to absorb vitamin B12 decreases with age, making the body susceptible to deficiency of this nutrient. Therefore, people over 40 years old are at higher risk of vitamin B12 deficiency than younger people.
Long-term vitamin B12 deficiency will cause the following symptoms in the legs:
Weakness in the legs and feet
One of the warning signs of vitamin B12 deficiency is a feeling of weakness and fatigue. This condition appears especially clearly in the legs and feet, sometimes greatly affecting work and daily activities.

Therefore, a lack of vitamin B12 will affect nerve signal transmission, affecting the body's coordination of movements. People with this condition will find it difficult to maintain balance when walking.
Tingling in the legs
Vitamin B12 deficiency not only affects the ability to transmit nerve signals but also causes nerve damage. . The result is a tingling sensation like needles in the feet and hands.

Some cases of vitamin B12 deficiency will cause swelling and inflammation in the feet. Experts believe that because the body does not receive enough vitamin B12, it affects some functions in the body, leading to fluid accumulation in the legs.
Weak joints
