The most effective type of CBD oil for you will depend on your specific needs and reasons for using CBD. Our bodies are different from one another, so one person’s reason for buying CBD oil tinctures might not be the same as yours. Based on your needs and preferences, you might find full-spectrum CBD to be the best fit since it contains CBD and secondary cannabinoids like THC to offer whole-body benefits from the entourage effect. Broad-spectrum CBD and CBD isolates may be more effective for those who are more cautious about THC content. CBD isolate is pure CBD without any other hemp compounds, but broad-spectrum CBD includes certain whole-plant hemp compounds, minus the THC.
