Whether you’re new to CBD or refining your routine, this guide helps you understand label-led starting amounts across oils, capsules, edibles, vapes and topicals.
Consistency matters more than “high strength” — the aim is to find a sensible starting range, track what you’re taking using mg per serving, and adjust gradually.
UK-Focused • Label-Led • Information Only (Not Medical Advice) • FSA Precautionary Guidance Included
Begin with a small amount and increase gradually over time. The aim is to find the lowest amount that suits your routine.
Not just “total CBD” on the front of the pack — mg per serving is the clearest way to compare.
Example: 600mg in a 30ml bottle equals 20mg per ml. Your product label (or product page) should help you estimate per serving.
Try the same serving size for several days before changing anything. Consistency makes comparison easier.
Oils, capsules, edibles and vapes can feel different depending on how they’re used. Choose a format that fits your lifestyle and preferences.
If you’re pregnant, breastfeeding, taking medication or managing a health condition, speak with a healthcare professional before using CBD.
Use this chart to estimate a starting range based on body weight and a chosen strength band.
Treat it as general guidance (not medical advice). Always check your product label for mg per serving, and adjust gradually over time.
Estimate a sensible starting range using your weight and a preferred strength band. Then convert that range into real servings by checking your product label for mg per serving (or mg per ml for oils).
Enter your body weight and preferred strength to get a personalised dosage recommendation. Use this as a gentle starting point and adjust slowly over time.

Start low and increase slowly as needed.
This calculator provides general guidance only and is not medical advice. Individual responses vary. Start low, increase gradually, and follow product label serving information. UK FSA precautionary advice recommends healthy adults limit CBD from food to 10mg per day. Under-18s, people who are pregnant/breastfeeding/trying to conceive, and anyone taking medication should speak to a healthcare professional before using CBD.
Check the total CBD (mg) and bottle size (ml). Divide total mg by total ml to get mg per ml. Then use the label’s suggested serving (for example, 0.5ml) to estimate mg per serving. If your product page lists mg per serving, use that as your primary reference.
Timing varies by format and by person. Oils and vape products are typically faster, while capsules and edibles can take longer. Start with a consistent routine and compare gradually.
More is not always better. Start low and increase gradually. The FSA’s precautionary advice recommends healthy adults limit CBD from food to 10mg per day. If you feel unsure, speak to a healthcare professional.
CBD itself is not intoxicating. Products can vary by spectrum type and cannabinoid profile, so always check the label and product information.
CBD products sold in the UK must meet specific requirements, including limits around controlled cannabinoids and accurate labelling. We recommend choosing reputable retailers and checking labels carefully.
