What to Know Before You Dose

This guide is for educational purposes only and isn’t medical advice. Talk to a licensed clinician—especially if you have liver disease, take prescription meds, are pregnant or breastfeeding, or have a history of substance use or serious mental health conditions.

• Interactions: CBD can affect drugs metabolized by CYP3A4/CYP2C19 (e.g., warfarin, clobazam, SSRIs, benzodiazepines). Always consult your prescriber.

• Legal note (USA): Hemp-derived CBD (<0.3% THC) is federally legal; state laws vary. Check local regulations.

CBD Dosage Chart by Weight & Experience

The values below use these general guidelines:

Beginner: 0.2 mg/kg/day

Intermediate: 0.5 mg/kg/day

Experienced: 0.8 mg/kg/day

Note: 1 kg ≈ 2.2 lb. Do not exceed 1 mg/kg/day unless advised by a clinician.

How to split doses

• If your total is under 30 mg/day: take once daily with food.
• If your total is 30–60 mg/day: take morning and evening.
• Over 60 mg/day: split into 2–3 doses and consult a clinician.

Beginner Dosing: A Simple 3-Step Plan

1. Days 1–7: Take the beginner amount from the chart once daily. Track how you feel 2–4 hours later and the next morning.
2. Days 8–14: If needed, increase by 5–10 mg/day. Keep a daily log of energy, mood, sleep, and any side effects.
3. After 2 weeks: Maintain your effective dose. If you exceed 1 mg/kg/day or need rapid escalation, consult your clinician.

Consistency beats intensity. CBD often works best after steady daily use for 1–2 weeks.

Real-Life Example

Jess, 34 (160 lb/73 kg), CBD-naïve: The chart suggested 15 mg/day. She started with a 30 mg/mL oil at 0.5 mL nightly (≈15 mg). After 5 nights, she noted milder evening tension but wanted a little more support, so she increased to 0.6 mL (≈18 mg). Within 10 days, she reported more restful sleep and kept a steady 18 mg nightly without daytime grogginess.

Practical Dosing Conversions

Oils/Tinctures

• Check label: total mg per bottle ÷ bottle size (mL) = mg per mL.
• Example: 900 mg in 30 mL = 30 mg/mL. Full dropper (1 mL) ≈ 30 mg; half dropper ≈ 15 mg.

Gummies & Capsules

• Pre-measured: 10 mg, 20 mg, or 25 mg each are common. Start with one and adjust weekly.

Topicals

• Mostly local effects; not ideal for calculating systemic dosing.

Quality Checklist: Choose Products You Can Trust

• COA: Independent lab results matching the product’s batch. Verify CBD mg and THC < 0.3% for hemp products in the USA.
• Spectrum: Full-spectrum (contains trace THC), broad-spectrum (THC-free), or isolate (CBD only). If drug-testing is a concern, choose broad-spectrum or isolate.
• Transparent labeling: Clear mg per serving, serving size, ingredient list, and contact info.

Timing, Onset, and What to Expect

• Onset: Oils: 30–90 minutes; gummies/capsules: 60–120 minutes.
• Peak: 2–4 hours after dosing; steady benefits often build over 1–2 weeks.
• With food: Taking CBD with a meal (especially some fat) can increase absorption and consistency.

When to Talk to a Clinician

• You take prescription medications with interaction risks (anticoagulants, anti-seizure meds, certain antidepressants, etc.).
• You have liver disease or plan to use higher/long-term doses.
• You’re pregnant, trying to conceive, or breastfeeding.
• You experience persistent side effects or no benefit after 3–4 weeks.
