People are always asking, “what health supplements should not be used with CBD?” CBD is perfectly safe to use with most health supplements. CBD is unlikely to interact negatively with most herbal or nutritional supplements. There are a few exceptions.

Supplements that have a sedative effect, reduce blood pressure, or lower blood sugar may increase the chances of side effects from CBD due to the similar side effects of the supplements. For example, taking an herbal supplement like Gymnema, an herb that lowers blood sugar, along with CBD, may increase CBD’s effects on blood sugar, which might make the combination stronger than desired. This combination, while not dangerous, could leave you feeling dizzy or lightheaded.

You need to be cautious about combining CBD with other supplements if you have underlying medical conditions.
