It’s up to you and how CBD oil impacts your body. Some people prefer taking it in the morning, as it helps them wake up and boosts their levels of productivity. Other people stick to night-time usage, as it relaxes them and makes them feel drowsy and ready for bed. Other people take it in both the morning and the evening. In short, there’s no ‘right’ time of day to take CBD oil – you should take it whenever works best for you.
