Yes, magnesium glycinate can be taken in the morning. Taking it in the morning may help with daytime stress, muscle support, and energy without causing significant drowsiness. However, some people may find it relaxing enough to make them feel sleepy, in which case taking it at night might be better. It is generally recommended to take magnesium glycinate with food to improve absorption and reduce any potential digestive discomfort. If using it to support sleep, taking it 30 to 60 minutes before bedtime is ideal, but for other benefits, morning or split doses throughout the day are effective.
