Frequent Questions And Answers About CBN (Cannabinol)

What is CBN?

CBN, or Cannabinol, is a key cannabinoid found in hemp and is often included with other cannabinoids like CBD (Cannabidiol) and CBG (Cannabigerol) during the hemp extraction process. It is considered to be one of the "Big Six" cannabinoids and is found in small concentrations in Full Spectrum and Broad Spectrum CBD Oils.

In recent years an emerging body of clinical research has shown that CBN oil has a wide array of health benefits and may provide pronounced therapeutics effects.

While the effects of CBN differ from those of its well-known cannabinoid counterparts THC and CBD, clinical studies indicate that Cannaibinol possesses mild psychoactive effects and acts as a mild sedative, making it a popular natural medicine because it acts directly on endocannabinoid system receptor sites and neurotransmitters in the central nervous system.

Recent technological advances have made it possible to isolate CBN cannabinoids in significantly larger concentrations than previously available during the extraction process so that it can now be taken independently of other cannabinoid compounds like CBD.

CBN oil for sale online and through retail stores is available in various forms. Cannabinol can usually be found in Full Spectrum CBD Oil blends, but often in very small amounts that are well below the effective clinical dosage range. Our Zero High™ brand pure CBN oil isolate is one of the best CBN products available because it utilizes an extraction process that isolates only cannabinol in concentrations of 99%, resulting in a CBN oil that contains no additional cannabinoid, terpene, or plant compounds.

How much CBN (Cannabinol) should I take?

Clinical studies and clinical human trials indicate that CBN can be taken safely and with positive benefits in dosages ranging from 10 milligrams to 100 milligrams per day.

CBN oil products come in varying strengths, or concentrations but knowing which strength CBN formula to take is really easy to determine.

If this is your first time using Cannabinol, the best CBN product approach to take is starting with a lower dosage amount and working your way up until you find just the right amount for your specific needs.

This process, known as titration, will help you to identify the right daily intake based on your body's individual response to CBN.

The varying milligram amounts in our CBN oil products signify low (150-300mg), mid-range (750mg), high (1500mg) and maximum (3000mg) dose concentration. Each unique formula provides a higher dose of cannabinol— the active ingredient in our CBN oil products — per 1 mL dropper.

150MG CBN Oil
5 milligrams per mL (milliliter)

300MG CBN Oil
10 milligrams per mL

750MG CBN Oil
25 milligrams per mL

1500MG CBN Oil
50 milligrams per mL

3000MG CBN Oil
100 milligrams per mL

To determine your ideal daily intake you can follow the following titration guidelines:

  • Utilize the included graduated dropper measurements and begin with taking between 5 to 10 milligrams of CBN oil. Wait between 1 to 2 hours to identify your body's response.
  • Increase the number of milligrams in your next dose if necessary until effects become apparent.
  • Do not exceed 100 milligrams of CBN in any 24 hour period without first speaking with your doctor.

We've created our formulations with ease-of-use in mind.

You'll find that each bottle of our CBN oil contains 30 milliliters (mL). If taking 1mL daily, your bottle will last approximately 30 days.

The amount of CBN you take on a daily basis will depend on your individual response to the formulation. For some, 10 milligrams before bedtime is enough, while others may take up to 100 milligrams of CBN at a time.
