A clearer way to choose CBD oil in the UK
CBD oils can look similar while differing in their contents, labelling and regulatory status. Use the label, the FSA’s public list and a batch-specific lab report to make a more informed comparison.
If you are comparing CBD oils, a high-strength label or a “full spectrum” claim does not tell you on its own what is in the bottle or whether the product is on the Food Standards Agency’s public list. Start by checking how much CBD you would take, then see whether the paperwork matches the product and its batch. The checks below also explain the FSA’s current daily advice, why the older 70 mg figure still appears, and how to spot claims that deserve a closer look.
What should you check before comparing CBD oils?
Begin with the product’s regulatory status, not its marketing claims. In England and Wales, the Food Standards Agency (FSA) says CBD foods need novel food authorisation to be sold legally. Its public list covers products linked to applications progressing through the process; the FSA says inclusion is not an endorsement, does not mean a product has been fully assessed for safety, and does not guarantee authorisation. Search for the exact product, not just the brand, on the FSA’s CBD guidance and public list.
The FSA also advises healthy adults to limit CBD from food to 10 mg a day. The 70 mg figure is older interim advice from 2020, not the current limit: the FSA replaced it after new evidence, as its updated advice explains. Check the label for CBD per serving and count any CBD from other foods or supplements towards your daily total. The FSA’s advice is precautionary, not a recommended dose or a promise of benefit. If you take medication, are pregnant or breastfeeding, trying to conceive, or under 18, the FSA advises against consuming CBD unless under medical direction.

What should the label and lab report tell you?
Look for the total CBD in the bottle and the amount per serving. “Strength” can be expressed in different ways, so check the actual milligrams (mg), bottle volume and suggested serving rather than comparing percentages or marketing terms alone. If the serving size is unclear, or you cannot work out how many milligrams it contains, you cannot reliably track your intake against the FSA’s advice.
A certificate of analysis (COA) is a laboratory report of a tested sample. Prefer a report that identifies the same product and batch number as the bottle, gives a test date and shows measured CBD and other cannabinoids, including THC. A report without a matching batch number, one that only gives a generic company name, or one that cannot be opened is weak evidence about the contents of the bottle you are considering. A COA can help check what a sample contained; it does not prove that a product is authorised, suitable for you or effective.
Do full-spectrum, broad-spectrum and isolate mean the same thing?
No. These terms describe different extract profiles, but labels alone may not tell you precisely which cannabinoids are present. “Full spectrum” generally refers to an extract containing CBD and other naturally occurring plant compounds, potentially including THC. “Broad spectrum” usually describes an extract with multiple cannabinoids but with THC removed or reduced; “isolate” refers to highly purified CBD. Ask what the seller means by the term and check whether the COA supports the claim.
Do not assume that “THC-free” or “full spectrum” guarantees a particular legal status or test result. Check the actual cannabinoid results for the product’s batch and the official rules that apply to the product. CBD food products remain subject to novel food requirements regardless of which spectrum label a seller uses.
How can you compare products without being led by the headline claim?
Compare like with like: CBD per bottle, CBD per serving, the carrier oil and ingredients, the batch-specific test information, and the exact FSA list entry. A lower price per bottle does not necessarily mean better value if the CBD amount or serving information differs. Likewise, “natural”, “premium” or “high strength” are not substitutes for clear quantities and verifiable product details.
Be wary of products that promise to treat or prevent a condition, imply that stronger is automatically better, or make dramatic claims about sleep, stress, pain or athletic recovery. The NHS notes that CBD supplements do not come with a guarantee of good quality or health benefits. Avoid relying on testimonials or influencer recommendations as evidence of what a product contains or what it will do for you.
How do you put your choice into practice?
Before buying, check the exact product on the FSA list, read the full label, and compare its stated CBD content with a report for the same batch. If the report, quantity or product identity cannot be verified, treat that as a reason to pause rather than fill in the gaps with a seller’s reassurance. Keep in mind that an FSA list entry is not final authorisation.
If you decide to use a CBD food product, follow the FSA’s current advice and count all CBD consumed that day. Do not treat 70 mg as a target: it is the superseded figure. If you take medication or fall into another group for whom the FSA advises against CBD, speak with a healthcare professional before considering it.
What should you review after choosing an oil?
Keep the packaging and note the product name, batch number, serving amount and the date you started. If the company changes its formula or batch, an earlier lab report may no longer describe what is in the new bottle. Recheck the report and official product listing rather than assuming that a familiar brand name means the details are unchanged.
Stop and seek appropriate advice if you experience an unwanted effect. Do not increase the amount because a product has not produced a noticeable result: CBD’s effects and safety are not established by a label claim, and more is not automatically better. For other forms of CBD use, such as CBD vaping, the route and product differ, so the checks for an oil do not answer every safety or legal question.
Frequently asked questions
Does being on the FSA’s CBD list mean a product is approved?
No. The FSA says products on its public list are linked to applications progressing through the novel foods process, but they have not been fully assessed for safety and inclusion is not an endorsement or guarantee of authorisation. Check the list as one part of your decision, not as proof that a product is approved or suitable for you.
Is full-spectrum CBD oil legal in the UK?
The words “full spectrum” do not establish whether an oil can legally be sold as food or a food supplement. CBD food products require novel food authorisation, and product status depends on the specific product and applicable rules. Check the product’s FSA list status and current official guidance rather than relying on a spectrum label or a seller’s general claim.
Can CBD affect medicines or cause side effects?
It may. The FSA advises people taking medication not to consume CBD unless under medical direction, and notes that people who are pregnant, breastfeeding, trying to conceive or under 18 should also avoid it. If you take medicines or have health concerns, speak to a healthcare professional before using CBD; a lab report cannot establish whether it is safe for you.
