The three-part CBD dosing framework
Clinicians who study cannabinoids use a simple mantra: start low, go slow, stay tolerant. Translated:
- Start low so you learn how your body responds before you feel any side effects.
- Go slow — increase in small steps every 3–5 days, not daily.
- Stay tolerant — stop increasing once you feel the effect. More isn't better with CBD; the dose-response curve is bell-shaped.
CBD dosage by weight (starting doses)
Multiply your body weight by 0.25 mg for a gentle starting dose, and 0.5 mg for a stronger one.
- 100 lb / 45 kg: 15–25 mg
- 150 lb / 68 kg: 20–35 mg
- 200 lb / 91 kg: 25–50 mg
- 250 lb / 113 kg: 30–60 mg
These are starting doses. For chronic pain or serious insomnia, adults often work up to 50–100 mg per day, split into two doses.
Dose by goal
Daily calm / mild stress
10–25 mg once or twice a day. Consistency matters more than dose size here — CBD builds up in your endocannabinoid system over about two weeks.
Sleep
25–50 mg 30–60 minutes before bed, ideally with 3–5 mg CBN. See our best CBD for sleep guide.
Joint discomfort or workout recovery
25–50 mg twice daily, plus a topical applied directly to the area. Topicals don't reach the bloodstream — you can use them alongside oral CBD without doubling your systemic dose.
Everyday anxiety before events
The often-cited 2019 Brazilian study on public speaking used 300 mg CBD 90 minutes before the event. That's on the high end — most people find 40–60 mg is enough for meetings and travel nerves.
How to read a CBD label
The number that matters is milligrams per serving, not milligrams in the whole bottle. A 3,000 mg tincture in a 30 mL bottle delivers 100 mg per full dropper — much stronger than a 750 mg bottle at 25 mg per dropper.
With gummies, always divide the bottle total by the count. A "1,500 mg" bottle of 60 gummies is only 25 mg per gummy.
When to stop increasing
If you notice any of these, hold your current dose or step down:
- Daytime drowsiness
- Dry mouth that doesn't resolve with water
- Changes in appetite
- Diarrhea or nausea
Frequently asked questions
How much CBD should a beginner take?
Most adults do well starting between 15 and 25 mg once daily. If you feel nothing after 5–7 days, increase by 5–10 mg every few days until you find a dose that works.
Can you take too much CBD?
Studies have shown doses up to 1,500 mg per day are generally well tolerated. Side effects at high doses include drowsiness, dry mouth, and changes in appetite. There is no known lethal dose in humans.
How much CBD is in one dropper?
A standard 30 mL tincture with 1,500 mg CBD contains about 50 mg per full 1 mL dropper — so 0.5 mL = 25 mg, 0.25 mL = 12.5 mg. Always check the label; concentrations vary.
Should I take CBD morning or night?
For daily anxiety or pain, split your dose morning and night. For sleep, take the full dose 30–60 minutes before bed.
