CBD Dosage Chart: The Short Answer
There is no official CBD dose. Not for sleep, not for anxiety, not for general wellness. What a dosage chart gives you is a starting range. For most adults new to CBD, that range is 5 to 10 mg once or twice a day, held steady for about a week before you adjust. Prescription CBD is the only form with published, fixed numbers, and that is a separate conversation with a doctor.
Everything below is a starting point, not a prescription. Your body will tell you more in two weeks than any chart can.
Why Online Dosage Charts Disagree
Search five charts and you will get five sets of numbers. Few of them are wrong. Dose depends on things no chart can see:
- Body weight and body fat
- How fast your liver processes cannabinoids
- Product type (oil, capsule, gummy, topical)
- Delivery method (under the tongue, swallowed, inhaled, rubbed on skin)
- What you are trying to address
- Other medications you take
- How consistent you are day to day
CBD also has a biphasic effect. Low doses and high doses can produce different, even opposite, results. More is not automatically better.
Starting Amounts by Goal
These ranges come from a mix of clinical research, product labeling, and what customers report back. Use the low end first.
Daily wellness
5 to 15 mg per day, once or twice. Plenty of people stay here and never move up.
Anxiety and stress
10 to 25 mg per dose. Clinical studies on anxiety have used single doses in the hundreds of milligrams, far above what a retail tincture serving delivers. Those studies were supervised, so do not copy a number off a headline.
Sleep
15 to 50 mg, taken 30 to 60 minutes before bed. If a higher dose leaves you groggy the next morning, cut it in half and try again.
Pain and inflammation
10 to 50 mg per dose, two to three times a day for ongoing issues. For one sore joint or a stiff back, a topical with 200 to 500 mg per container applied to the area is a reasonable first stop.
Seizure disorders
Prescription only. The approved drug Epidiolex is dosed by weight, roughly 5 to 20 mg per kilogram per day split into two doses, and only a neurologist should set that number.
The Weight-Based Rule of Thumb
You have seen the 1 to 6 mg per 10 pounds formula. A 150 pound adult lands somewhere between 15 and 90 mg a day, which is a 6x spread. That formula came from consumer charts, not clinical trials. Keep it as a sanity check on the high end, not as a target.
Do the Label Math Before You Buy
Two numbers matter: total milligrams in the bottle and total volume. A 30 mL tincture with 1500 mg works out to 50 mg per mL. If a full dropper is 1 mL, a half dropper is 25 mg. Some droppers hold 0.5 mL, so read the packaging. With capsules and gummies, look at milligrams per piece, not per bottle. A 1000 mg jar of gummies with 20 pieces is 50 mg each, and that is a big first dose.
Run this math in the store. A bottle that sounds strong can turn out to be 8 mg per serving, which means you are paying for carrier oil.
How Long to Wait Before Adjusting
Under the tongue: 15 to 45 minutes to onset, peak around 1 to 2 hours. Swallowed oil or edibles: 1 to 2 hours, with effects that can stretch to 6 hours or longer. Inhaled: minutes, shorter duration. Give any new dose 3 to 7 days before you decide it is not working. Bumping up daily is how people end up overshooting.
Signs You Took Too Much
- Drowsiness or heavy fatigue
- Dry mouth
- Loose stools or stomach upset
- Lightheadedness
- Foggy, flat mood
These are not usually dangerous on their own, but they are your cue to drop back to the last dose that felt fine. If you take blood thinners, seizure medication, thyroid medication, or anything with a grapefruit warning, talk to your prescriber first. CBD uses some of the same liver enzymes as those drugs.
Keep a Simple Log
Date, product, milligrams, time taken, and how you felt at the one hour and four hour marks. That is it. Three weeks of notes tells you more about your dose than any chart on the internet.
When to Call a Doctor Instead
Skip the chart if you are pregnant or breastfeeding, under 18, on prescription medication, or managing a condition that needs actual treatment. CBD is not a substitute for care, and the research on long term daily use is still thin.
