CBD Oil Dosage: How Much Do I Take?
There is no specific number for what dose of CBD oil to take, because the dose of CBD oil is a sliding scale that’s different for everybody.
The best way to find the right dose for your body is to start with a very low dose (2 mg, for example) and increasing by 2-5 mg per serving until you find the dose that works for you.
It’s hard to predict the optimal dose without using CBD for yourself, but there are a few general ranges for different people based on metrics like age and weight to help make an educated guess as to the correct dose.
It’s better to start with a lower, ineffective dose and build up to a higher, effective dose gradually. You don’t want to take way too much the first time and experience uncomfortable side effects for the rest of the day.
General Rule of Thumb for Choosing a Dosage Strength:
Low strength → 1 mg CBD per 10 pounds (0.2 mg/kg)
Medium strength → 3 mg CBD per 10 pounds (1.0 mg/kg)
High strength → 6 mg CBD per 10 pounds (1.5 mg/kg)
It’s important to note that this measurement is in pure CBD, not CBD oil.
Doses of CBD by Weight & Strength (in mg)
Weight (lbs) Low Strength Medium Strength High Strength
100 lbs 10 mg 30 mg 60 mg
125 lbs 13 mg 38 mg 75 mg
150 lbs 15 mg 45 mg 90 mg
175 lbs 17 mg 52 mg 105 mg
200 lbs 20 mg 60 mg 120 mg
225 lbs 22 mg 67 mg 135 mg
250 lbs 25 mg 75 mg 150 mg
Ask Yourself: “What am I Taking CBD for Exactly?”
This is an important question to ask because it will guide you in the direction of the right dose to take.
Recommended Strength by Condition
General health → low strength
Nausea → low to medium strength
Chronic pain → medium to high strength
Sleep disorders → medium to high strength
Anxiety → medium to high strength
Epilepsy → high strength or pharmaceutical grade
Cancer → high strength or pharmaceutical grade
Migraines → low to high strength
Dosing CBD: You'll need these 4 steps to dose properly:
The easiest way to start dosing is to find where you fall in the Weight & Strength chart above, start dosing with the low strength and build your way up from there.
Never start at the high strength if you've never used CBD oil before. If you want to get even more accurate with your dosing, follow the 4 steps below.
Step #1: Determine the Potency of Your CBD Oil The first step is to look at the CBD oil you have and determine its potency. Sometimes the manufacturers will make this super easy for you, and tell you the concentration of CBD per mL of oil. However, in most cases, this isn’t provided and you may need to do some quick calculations for yourself.
This may seem intimidating at first, but it’s actually pretty simple. All you need to do is enter the numbers into the formula below. Here’s What You Need to Take Into Account:
Bottle size (in mL)
Amount of CBD listed on the bottle (300 mg, 600 mg, 1000 mg)
Use This Formula to Calculate Potency: [CBD IN MG] ÷ [BOTTLE SIZE IN ML] = [CBD IN MG/ML] Let’s use an example. Lakeside offers an oil that advertises 600 mg. The bottle size is 1oz (30 mL). Let’s put this into our formula: [600 MG] ÷ [30 ML] = [20 MG/ML CBD]. Our Answer: 20 mg CBD for every 1 mL of liquid.
You can compare this to the reference chart above to see how much oil you’ll need to get the desired strength of CBD, to determine your dose. Now that we know this, the next step is to see how much fluid the dropper holds. This will make dosing much easier later.
Step #2: Measure the Volume of Your Dropper The dropper is the part of the bottle that’s used to dole out the CBD oil. It usually comes with a squeezable head and a glass tube.
It makes it easy to give exact doses of CBD oil in drop doses.
Most droppers are designed to hold exactly 1 mL of fluid. You should end up somewhere around 20 drops. Keep this number in mind for the next step.
Step #3: Calculate Your Dose So now you need to decide on the dose you’re going to take. Here’s the General Rule of Thumb for Dosing According to Weight & Strength:
Weight Metric Low Strength Medium Strength High Strength
Imperial (pounds) 1 mg every 10 lbs 3 mg every 10 lbs 6 mg every 10 lbs
Metric (kilograms) 1 mg every 4.5 kg 3 mg every 4.5 kg 6 mg every 4.5 kg
How To Calculate Dose From Your Weight [YOUR WEIGHT IN POUNDS] ÷  x [DESIRED STRENGTH IN MG] = [YOUR DOSE]
If you prefer metric, the formula changes only slightly: [YOUR WEIGHT IN KG] ÷ [4.5] x [DESIRED STRENGTH IN MG] = [YOUR DOSE]
Here’s an example of this in practice: Let’s say you’re a 170-pound male, and you’re looking for a medium strength dose. You need to first divide your weight in pounds by 10 to see how many sets of 10 you have in your weight.  ÷  = 17. Now you simply multiply 17.5 by the medium strength dosage guideline, which in this case is 3.  x [3 mg] = 51 mg CBD So a good starting dose for you would be about 52 mg CBD per day in this case.
Step #4: Tweak The Dose To Match Your Body This is one of the most important steps. Let me tell you why. As mentioned earlier, everyone responds to CBD oil differently. This means that you need to assess how it affects you individually, rather than going off the experiences of everyone else. Your friend may find the right dose at 20 mg, while you may require far more, or far less. The only way to really identify this is to start with the dose calculated above, and then tweak it from there.
