Tag: B vitamins and sleep

According to a study published in the journal *Cell Metabolism*, many metabolic enzymes involved in nutrient processing are most active during daylight hours, but that doesn't mean nighttime supplementation is ineffective. While some people prefer taking vitamins in the morning, taking them before bed is a feasible option for many, provided you know the potential implications.

According to nutrition experts, a multivitamin is best taken with a meal to improve absorption and prevent stomach upset. The specific time of day—morning or evening—is often less critical than ensuring you take it consistently alongside food, though some specific vitamin types are better suited for certain times.

Approximately 70 million Americans suffer from chronic sleep problems, and the timing of vitamin supplements could be a contributing factor. Taking a B complex at night can potentially interfere with your sleep due to its role in energy production, but the effect varies significantly among individuals.
