Many people experience periods of fatigue. It is often caused by stress, a busy lifestyle, or insufficient sleep, but if the tiredness persists, there may be other explanations.
Researchers examined 602 healthy adults. Participants answered questions about their energy levels and motivation, while the researchers analyzed various substances in their blood. The results were published in the journal Nutrients cited by Prevention.
Important nutrients
Among other things, the researchers examined homocysteine, which often increases when the body lacks certain B vitamins.
The study showed that people with high levels of homocysteine typically had lower levels of specific vitamins.

Men reported fatigue more frequently, while women were more likely to experience low motivation.
However, experts emphasize that fatigue is not always caused solely by vitamin deficiencies. If symptoms persist, individuals should consult their doctor.
Chronic fatigue
If a vitamin deficiency is suspected, a blood test can provide answers. Diet may also play a role.
Vitamin B12 is found in foods such as fish, meat, eggs, and dairy products, while folate is found in green vegetables, beans, lentils, and citrus fruits.

People with low levels of vitamin B12 and folate were at greater risk of chronic fatigue.
The researchers therefore believe that these vitamins may be worth investigating in people experiencing persistent, unexplained fatigue.
