Bison Botanics CBD isolate oil tinctures contain zero THC. We use MCT oil as a carrier which means our isolate tinctures have little to no taste or odor. All of our tinctures come with graduated droppers that will allow for easy portion control. We have all of our tinctures third-party lab tested for potency. If you have any questions about the difference between CBD isolate oil tinctures and full spectrum CBD oil tinctures feel free to reach out to us.
