Best Time to Take Lion's Mane

Since Lion's Mane may have an energizing effect on some individuals, it is generally recommended to take it earlier in the day to avoid any potential disruption to sleep patterns. However, if you find that it has a calming effect on you, taking it closer to bedtime may provide more restful sleep. The effects of Lion's Mane can vary from person to person, so it's essential to pay attention to how your body responds to determine the best time for consumption.
