Total CBD
The main mg figure often describes the CBD stated for the whole bottle, pack or container. It is not automatically a per-serving figure.

Four Strength Details That Are Easy To Confuse
Several figures may appear together. Each answers a different question, so keep them separate when comparing products.
Essential context
Size Or Count
Bottle volume, product weight or the number of equal pieces gives the total CBD figure the context needed for comparison.
Like for like
Concentration
CBD per ml or per gram shows how the stated total relates to a product’s volume or weight when the label supplies enough information.
Measured formats
Per Unit Or Stated Serving
Gummies, capsules and drinks may state CBD per item or serving. Check whether the brand’s stated serving contains one unit or several.

This result explains the label maths only. It is not a serving recommendation. Follow the current product label.
Worked examples
How The Label Maths Works
These examples show arithmetic only. They do not recommend a serving and must not replace the actual product label.
01
CBD oil
1,000mg In A 10ml Bottle
1,000mg÷10ml=100mg/ml
This compares concentration. Use the label’s own drop or stated-serving information because drop size is not universal.
02
CBD gummies
300mg Across 30 Equal Gummies
300mg÷30=10mg each
This works only when the stated total is distributed evenly. Check whether the brand’s stated serving contains one gummy or more.
03
CBD capsules
600mg Across 60 Equal Capsules
600mg÷60=10mg each
Per-capsule CBD and the brand’s stated serving are different details. Read both before making a comparison.

Current UK consumer guidance
The FSA Advises Healthy Adults Not To Exceed 10mg CBD A Day From CBD Food Products
The FSA currently advises healthy adults not to consume more than 10mg CBD per day from CBD foods and food supplements in total. Treat this as a recommended maximum, not a personal target or serving recommendation.
CBD Food Products
For healthy adults, the FSA advises a maximum daily intake of 10mg CBD from CBD foods and food supplements in total. Count relevant sources across the whole day.
Maximum, Not A Target
Treat 10mg a day as the FSA’s recommended maximum for healthy adults using CBD food products, not as a target to work towards or a universal serving instruction.
Vulnerable Groups
The FSA advises vulnerable groups—including under-18s, people taking medication, those trying to conceive, and people who are pregnant or breastfeeding—to avoid CBD unless under medical direction.
Strength questions
CBD Strength & Serving FAQs
Clear answers about label figures, comparison maths and the boundary between product information and personal advice.
Does the largest mg number tell me the serving size?
No. The largest mg figure often describes total CBD for the whole product. Check the bottle or pack size, per-unit information and the brand’s stated serving directions separately.
How do I compare two CBD oils?
Compare total CBD with bottle volume, then calculate CBD per ml where both figures are clearly supplied. Also check CBD type, ingredients, flavour and the current label directions.
Can I calculate CBD per drop from CBD per ml?
Only when the product supplies a reliable drop volume or drops-per-ml figure. Drop size can vary between droppers and products, so do not assume a universal conversion.
What does the FSA’s 10mg figure mean?
For CBD food products, the FSA currently advises healthy adults not to consume more than 10mg CBD per day in total. Treat this as a recommended maximum, not a personal target or a universal serving instruction.
Can this calculator tell me how much CBD to use?
No. It converts figures already stated on a product label into a common comparison unit. Follow the current product label and seek qualified medical advice if you need guidance specific to your circumstances.
