Choosing the best potency comes down to preference. The 300 mg bottle is a great way to experience first-hand the effects of taking CBD. Think of it like a multivitamin. The 600 mg bottle provides a significant health boost for people wanting to get more from CBD. This is our most popular oil. Finally, 1000 mg is our most powerful oil. This product has been formulated for people that have a specific health effect in mind and want to achieve it fast.
