There is no universal CBD dose. This guide provides the Start Low, Go Slow method, guidelines by format (oil, capsules, infusion, vaporization), and an interactive quiz for a cautious and personalized recommendation.
Responsible information: CBD is generally well-tolerated, but there is no universal dose. Start low, increase slowly. Do not exceed 70 mg/day without medical advice. In case of medication, pregnancy, breastfeeding, or psychiatric history: consult a healthcare professional. See CBD and medications.
Start Low, Go Slow Method: the golden rule of CBD dosage
Golden Rule
Optimal dosage depends on your weight, metabolism, intensity of need, tolerance, and the format chosen. The most effective strategy: start small, observe for 3 to 5 days, then adjust in increments. Lasting effects are built over 2 to 3 weeks of regular use.
Week 1 — Minimum dose
Example: 2–3 drops of 5–10% oil, 2× per day
Observe how you feel without changing the dose
Keep a journal (time, dose, feeling)
Week 2 — Gradual adjustment
If needed, add +1 drop per dose
Allow 3 to 5 days between each step
Avoid rapid redosing
Weeks 3–4 — Stabilization
Adjust based on felt effects
Take at fixed times to stabilize
Aim for the smallest effective dose
Factors influencing dosage
Body weight: more weight may require a little more
Good to know: the most lasting "baseline" effects often set in after 2 to 3 weeks of regular use. Patience + consistency = more reliable results. See How long does it take for the effects to be felt?
Bioavailability by format: why the administration route changes everything
Comparative table
Bioavailability measures the amount of CBD actually absorbed by your body. It varies greatly depending on the format — this is a key criterion for adjusting your dose.
Soothing ritual, evening, improved absorption with fatty foods
🧴 Cosmetics (topical)
Cutaneous
Local
15–45 min
Variable
Local comfort, skin, joints — no systemic effect
Indicative data. Bioavailability varies depending on product quality, spectrum, and individual conditions.
💡 Absorption tip: for capsules and infusions, take with a meal containing fats (avocado, oil, nuts). CBD is fat-soluble: bioavailability significantly increases with lipids.
Very fast absorption via inhalation. Ideal for targeted, occasional action. Choose a verified e-liquid (COA analysis) with or without nicotine depending on your profile.
💡 Beginner's tip: try taking it in the evening for your first time. The calm environment makes it easier to observe your feelings and tolerance. See The Cannabinoid Guide.
CBD dosage by profile and need
User profiles

Important: this result is informative. In case of medical treatment, pregnancy/breastfeeding or doubt, consult a healthcare professional. See CBD and medications and CBD side effects.
For beginners, start with 2–3 drops under the tongue, 2 times a day, then gradually increase if needed. Wait 3 to 5 days between each adjustment. The number of drops equivalent to mg depends on the oil's concentration.
Can you overdose on CBD?⌄
CBD is generally well-tolerated — there is no "dangerous overdose" in common use. We recommend, however, not to exceed 70 mg/day without medical advice. In case of excess, possible adverse effects include drowsiness, dry mouth, or digestive issues. See CBD side effects.
How long does it take to feel the effects of CBD?⌄
It depends on the format: sublingual oil = 15–30 min · capsules and infusions = 45–90 min · vaporization = 5–10 min. The most lasting "baseline" effects often build up over 2 to 3 weeks of regular use. See How long does it take to feel the effects?
What oil concentration should I choose to start?⌄
For a beginner, a 5–10% oil is ideal: the dosage is easier to control and gradual adjustment more comfortable. Concentrations of 15–20% are more for regular use, and 25–30% for intense needs. See How to choose your CBD product?
Can different CBD formats be combined?⌄
Yes: for example, oil in the morning + infusion in the evening. Adjust your total dosage by accounting for all formats and stick to a gradual approach. Monitor your daily total (max 70 mg/day without medical advice).
CBD, CBG, CBN: which to choose depending on the need?⌄
CBD: versatile, basis of any well-being routine · CBG: more focused on focus, mental clarity, active day (CBG Guide) · CBN: more focused on sleep, deep relaxation (CBN Guide). They can be intelligently combined depending on the time of day. See The Cannabinoid Guide.
Full Spectrum or Broad Spectrum: what impact on dosage?⌄
A Full Spectrum product contains legal traces of THC + a full spectrum of cannabinoids and terpenes — the entourage effect can intensify effects at an equivalent dose. A Broad Spectrum or isolate product is 0% THC: useful for athletes subject to controls. See Terpenes & Entourage Effect and CBD vs THC Guide.
What time of day should I take my CBD?⌄
It depends on your objective: morning → CBG for focus/energy · daytime → CBD for stress/balance · evening → CBN for sleep/relaxation. If you're starting, try it in the evening in a calm environment to assess your tolerance without friction.
