Why does vitamin B complex make me sleepy?

Vitamin B complex is a group of 8 B vitamins that play an essential role in maintaining a healthy body. Vitamin B is known to be involved in the production of hormones, energy metabolism, and the development of new cells.

This can lead to a temporary rush of energy followed by an “energy crash,” causing the body to become fatigued and lead to sleepiness. Another side effect can be increased anxiety due to the energy rush.

Additionally, Vitamin B is known to affect cognitive functioning, including concentration and focus, which can also contribute to feelings of tiredness and drowsiness. Therefore, it is usually recommended to take B complex vitamins with food and reduce the overall dosage to avoid side effects.
