Are There Any Health Supplements That Can't Be Used With CBD?

Most health supplements are perfectly safe to use with CBD. It’s unlikely for CBD to interact with most nutritional or herbal supplements — with a few exceptions.

Supplements that reduce blood pressure, reduce blood sugar, or produce a sedative effect may increase the chances of side effects from CBD due to similarities in their effects.

For example, taking CBD with a herbal supplement like gymnema (herb for lowering blood sugar) may increase the effects of CBD on blood sugar and make the combination too strong. While not inherently dangerous, this combination could make you feel dizzy or lightheaded.

It’s especially important to be cautious about combining CBD with other supplements if you have underlying medical conditions.
