Calculating the proper dosage for CBD oil can depend on several factors, including your weight, the condition you’re treating, the concentration of CBD in the oil, and individual factors like tolerance.

Here’s a general way to calculate your CBD Oil Dosage:
1. Start with your weight
A common rule of thumb for CBD dosage is 1-6 mg of CBD per 10 pounds of body weight.
- Low dosage: 1-2 mg per 10 lbs
- Medium dosage: 3-4 mg per 10 lbs
- High dosage: 5-6 mg per 10 lbs
2. Find your dosage
Use your weight to determine the starting dosage. For example, if you weigh 150 pounds:
- Low dose: 15 mg (150 / 10 = 15; 1 mg x 15)
- Medium dose: 30 mg (150 / 10 = 15; 2 mg x 15)
- High dose: 45 mg (150 / 10 = 15; 3 mg x 15)
3. Know the concentration of CBD in the oil
CBD oil is typically sold with a certain concentration, such as 300mg, 500mg, or 1000mg of CBD per 30mL bottle.
For example, if you have a 1000mg CBD oil in a 30mL bottle, each 1mL of oil contains approximately 33.3 mg of CBD (1000mg ÷ 30mL).
4. Calculate how much oil you need
If your desired dose is 30 mg and you have a 1000mg bottle with 30mL, here’s how to calculate:
- If 1mL contains 33.3mg, then you would need about 1mL of oil to get a 30mg dose.
5. Adjust based on your experience
Start with a low dose and gradually increase if needed. Monitor how you feel and how your body reacts to CBD over a few days to calculate your CBD Oil Dosage correctly.
Example Calculation
- Weight: 160 lbs
- Desired dose: 20 mg (medium dose)
- CBD oil concentration: 1000mg/30mL bottle
- 160 lbs / 10 = 16 (starting point for the dose in mg)
- Desired dose: 20 mg (for a medium dose)
- 1000mg/30mL = 33.3mg per 1mL
- 20 mg ÷ 33.3 mg per mL = 0.6 mL of oil (about 2/3 of a dropper, depending on the dropper size)
Key Reminder
- Start low, and increase slowly over time.
- Consult a doctor, especially if you’re taking other medications or have health conditions.
