How Much CBD Should I Take? A CBD Dosage Chart by Weight and Format
Zen Bliss team · October 2026
In short: Many adults start CBD at about 10 to 20 mg a day, for example half a dropper of a 1000 mg oil (about 17 mg) or a quarter to half of a 50 mg gummy, and hold that amount for three days before changing it. A common rule of thumb is 1 to 3 mg per 10 lb of body weight a day. Health Canada's science advisory committee found 20 to 200 mg a day, taken by mouth for up to 30 days, safe and tolerable for healthy adults.
Why there is no single right amount
There is no official CBD dose for everyday use in Canada. Health Canada has not approved CBD as a health product, so there is no label dose the way there is for an over-the-counter medicine or a vitamin. What exists is a safety range and some rules of thumb.
The safety range comes from Health Canada's Science Advisory Committee on Health Products Containing Cannabis. In its 2022 review of cannabidiol, the committee found CBD safe and tolerable for healthy, non-pregnant adults at 20 to 200 mg a day, taken by mouth, for up to 30 days, as long as they talk to a pharmacist about any other medications. That is advice, not a rule, and the committee did not conclude that CBD works for any particular purpose.
Within that range, how much suits you depends on a few things:
- Experience. People new to CBD usually start lower. Regular users often take more.
- Food. CBD dissolves in fat. Taken with a meal, especially a fatty one, your body can absorb several times as much as on an empty stomach. This can matter more than your weight.
- Format. Oil held under the tongue starts sooner than a gummy. A gummy lasts a little longer.
- Body weight. It plays a part, which is why most charts start from it, but it is one factor, not a formula.
- Your body. Two people can feel the same amount quite differently.
CBD dosage chart by body weight
This chart uses the same rule of thumb as our Dose Finder: 1, 2 or 3 mg of CBD per 10 lb of body weight a day, depending on how strong an effect you want. The figures are daily amounts for someone with some experience of CBD.
| Body weight | Mild (1 mg per 10 lb) | Moderate (2 mg per 10 lb) | Strong (3 mg per 10 lb) |
|---|---|---|---|
| 120 lb (54 kg) | 12 mg | 24 mg | 36 mg |
| 150 lb (68 kg) | 15 mg | 30 mg | 45 mg |
| 180 lb (82 kg) | 18 mg | 36 mg | 54 mg |
| 210 lb (95 kg) | 21 mg | 42 mg | 63 mg |
| 240 lb (109 kg) | 24 mg | 48 mg | 72 mg |
New to CBD? Take about 40% off. A 150 lb adult aiming for a moderate amount would start around 18 mg a day instead of 30. Use it most days? You may find you need about 30% more. Either way, the Dose Finder keeps its suggestion between 10 and 200 mg a day, inside the range Health Canada's committee reviewed.
Treat the chart as a starting point. If a smaller amount does what you want, there is no reason to take more.
What each amount looks like in gummies and drops
Milligrams are easy to read on a chart and harder to measure in a kitchen. Here is how common amounts work out with our THC-free products:
| Amount of CBD | CBD Gummies (50 mg each) | CBD oil, 1000 mg (about 33 mg per ml) | CBD oil, 2000 mg (about 67 mg per ml) |
|---|---|---|---|
| about 12 mg | a quarter of a gummy | about 7 drops | about 4 drops |
| about 17 mg | between a quarter and a half | half a dropper (about 10 drops) | about 5 drops |
| about 25 mg | half a gummy | three quarters of a dropper | about 8 drops |
| about 33 mg | between a half and a whole | one full dropper (1 ml) | half a dropper |
| about 50 mg | one gummy | one and a half droppers | three quarters of a dropper |
Oil figures are worked out from the label at about 20 drops per ml. Droppers and drop sizes vary, so treat drop counts as a guide; the graduated lines on the dropper are more reliable. The lab measured a little more CBD than the label states in our current 1000 mg and 2000 mg bottles; the reports are on our lab results page.
Oil is the easier format for small or precise amounts, because you can move up a few drops at a time. Gummies are simpler once you know your amount: one piece, the same every time. To compare the two in detail, see CBD gummies vs CBD oil.
Dosage by format
| Format | Usually starts in | Typically lasts | Good to know |
|---|---|---|---|
| Oil held under the tongue for 60 seconds | 15 to 45 minutes | 4 to 6 hours | Easiest to adjust by the drop |
| Oil swallowed or stirred into food | about an hour | several hours | Behaves more like a gummy |
| Gummy | 30 minutes to 2 hours | 4 to 6 hours | Can be cut into halves or quarters |
CBD with melatonin. Our CBD Sleep Gummies carry 50 mg of CBD and 3 mg of melatonin each, and our CBD oil with melatonin about 3 mg of melatonin per full dropper in every strength. With these, the melatonin sets the limit, not the CBD: Health Canada's maximum for adults is 10 mg of melatonin a day. Take one serving 30 to 60 minutes before bed, don't combine the two melatonin products, and don't drive for 5 hours afterwards. More on our CBD for sleep page.
Delta-8 THC is dosed differently. It is psychoactive, and tolerance to THC matters far more than body weight. A first amount is usually 5 to 10 mg. See How much Delta-8 should I take?
Pets need far less than people. Our CBD Oil for Pets is weaker per drop so small amounts are easier to measure, and the Dose Finder has a dog and cat setting. For cats, see CBD for cats: what you need to know.
How to start: your first week
- Days 1 to 3: take half of your starting amount, at the same time each day, with food.
- Days 4 to 6: if you feel fine and want more, move up to your full starting amount.
- After that: change by small steps, about 5 to 10 mg at a time, and hold each step for about three days.
- Keep a short note of what you took, when, whether you had eaten, and how you felt. It makes the next change easier to judge.
Change one thing at a time. If you switch from oil to gummies, or from morning to evening, keep the amount the same for a few days so you can tell what made the difference.
When to take less, or stop
If you feel more tired than you would like, or notice an upset stomach, take a smaller amount or take it with food. If an amount that seemed fine starts to feel like too much, step back to the last one that suited you. Stop and talk to a pharmacist or doctor if anything worries you.
Side effects and safety
In studies, the side effects most often reported with CBD are tiredness, dry mouth, an upset stomach or diarrhea, and changes in appetite. They are more likely at higher amounts. High daily amounts can also raise liver enzymes, which is one reason not to go higher than you need.
- Medications. CBD can change how the liver processes some medicines; blood thinners are the usual example. Talk to a pharmacist before using CBD if you take any prescription medication.
- Pregnancy. Do not use CBD during pregnancy or while breastfeeding.
- Driving. CBD may cause drowsiness. See how it affects you before you drive.
- Legal age. For adults of legal age in their province: 18 in Alberta, 21 in Quebec and 19 everywhere else.
- Storage. Keep gummies and oils sealed and out of sight and reach of children and pets. Gummies look like candy.
- Drug tests. Tests look for THC. Our CBD isolate products contain no THC, but no seller can guarantee a test result. See Will Delta-8 or CBD show up on a drug test?
FAQ
How much CBD should a beginner take?
Many people start at about 10 to 20 mg a day: half a dropper of a 1000 mg oil is about 17 mg, and a quarter of one of our gummies is 12.5 mg. Hold that for three days before changing it.
Is 50 mg of CBD a lot?
It is a full daily amount for many adults, and well inside the 20 to 200 mg a day that Health Canada's committee reviewed. It is more than most people need to start with, which is why we suggest half of one of our 50 mg gummies at first.
How many drops of CBD oil should I take?
It depends on the bottle. In a 1000 mg, 30 ml bottle, one drop is roughly 1.7 mg, so 10 drops is about 17 mg. In a 2000 mg bottle a drop is roughly 3.3 mg. The Dose Finder converts your amount into drops for each of our oils.
Can you take too much CBD?
Side effects become more likely as the amount goes up, and Health Canada's committee only reviewed up to 200 mg a day for healthy adults over 30 days. There is rarely a reason to go near that. If you feel unwell, stop and talk to a pharmacist or doctor.
Does body weight change how much CBD I need?
Somewhat, which is why charts start from it. Experience, whether you have eaten, and the format can make as much difference, so use the chart as a starting point and adjust from there.
Can I take CBD every day?
Many people do. Health Canada's committee looked at daily use for up to 30 days in healthy adults. If you plan to take it daily for longer, or you take other medication, check with your pharmacist.
How long does CBD take to work?
Oil held under the tongue usually starts in 15 to 45 minutes. Gummies take 30 minutes to two hours because they go through the stomach.
