CBD oil is well-known for its benefits and helping to calm the nervous system, thus relieving unnecessary anxiety and mental stress. High potency CBD tinctures 3000 mg, 1 dose may be 30mg. So 3000mg provides 100 doses. For many people this is a three month supply, and for others it’s a six week supply. Cbd single dose of 3000 mg is a waste of product because studies suggest that the best dose to relieve anxiety and stress is 200 mg total per day with much less benefit at higher doses.
