Hemp Oil vs CBD Oil UK: What's the Difference? | Valley CBD

Hemp oil and CBD oil are not automatically the same product. In most food contexts, plain hemp seed oil means an oil pressed from hemp seeds. It is not intended to provide a meaningful amount of CBD. CBD oil, by contrast, is specifically formulated to contain a stated amount of cannabidiol (CBD), usually by combining a CBD ingredient with a carrier oil.

The confusion comes from the loose way the phrase “hemp oil” is sometimes used online. It may refer to hemp seed oil, a hemp extract containing cannabinoids, or a CBD product that happens to use hemp seed oil as its carrier. The front label alone is therefore not enough to tell you what is in the bottle.

This guide explains how to tell hemp seed oil and CBD oil apart, how CBD strength is measured, what UK novel-food guidance says, and which label details matter when you are comparing products.

Hemp Oil vs CBD Oil: Quick Comparison

What Does “Hemp Oil” Actually Mean?

“Hemp oil” is an imprecise phrase. If you see it on a product page, check the ingredient list rather than assuming it means either CBD oil or hemp seed oil.

Three different products can all be described loosely using hemp-related wording:

• Plain hemp seed oil: an edible oil produced from hemp seeds.
• A hemp-derived cannabinoid extract: an extract produced from parts of the plant containing cannabinoids.
• A finished CBD oil: a measured CBD ingredient or extract diluted into a carrier oil, which may itself be hemp seed oil.

That last point is especially important. Hemp seed oil and CBD oil are not mutually exclusive ingredients. A manufacturer can use hemp seed oil as the carrier and add a measured CBD ingredient to it. The finished product would then be a CBD oil whose carrier happens to be hemp seed oil.

What Is Hemp Seed Oil?

Hemp seed oil is produced from the seeds of Cannabis sativa. It is sold as a conventional food ingredient and contains naturally occurring fats, including omega fatty acids.

It should not be confused with a product that has been deliberately formulated to deliver a stated amount of CBD. If a bottle is simply plain hemp seed oil, you would not normally expect it to be labelled with a CBD concentration such as 10%, 20% or 40%.

The Food Standards Agency’s current CBD guidance makes this regulatory distinction clear: hemp seeds and hemp seed oil themselves are considered non-novel foods because they have a history of consumption, whereas CBD extracts and foods to which CBD has been added are treated differently under the novel-food framework.

Read the current FSA/GOV.UK CBD novel-food guidance.

Does Hemp Seed Oil Contain CBD?

Plain hemp seed oil is not intended to be a meaningful source of CBD. That is more accurate than saying every hemp seed oil contains “zero cannabinoids”.

Commercial products can vary, and trace cannabinoids can be introduced through plant material, processing or contamination. A 2026 laboratory study of commercial hemp seed and hemp seed oil products sold in Türkiye detected cannabinoids, including CBD and THC, in a number of samples.

Read the 2026 commercial hemp seed oil cannabinoid study on PubMed.

That study does not mean every UK hemp seed oil contains detectable cannabinoids. It does show why an absolute statement such as “all hemp seed oil contains zero CBD and zero THC” is too strong without product-specific testing.

What Is CBD Oil?

CBD oil is a finished product deliberately formulated to contain cannabidiol. The CBD ingredient might be a purified isolate or a broader hemp-derived extract, depending on the product. It is then formulated with a carrier oil so the CBD can be supplied at a stated concentration.

Common carrier oils can include MCT oil, hemp seed oil and other food-grade oils. The carrier does not determine the CBD strength. The amount of CBD added to the finished volume does.

For example, an oil containing 6,000mg CBD in a 30ml bottle has a concentration of 200mg/ml. An oil containing 12,000mg in 30ml has a concentration of 400mg/ml. Those figures describe CBD concentration regardless of whether the carrier is MCT oil, hemp seed oil or another suitable oil.

Can Hemp Seed Oil Be Used to Make CBD Oil?

Yes. Hemp seed oil can act as the carrier in a CBD formulation.

This is not just a theoretical distinction. An FSA safety assessment for a specific CBD-isolate novel-food application describes highly purified CBD isolate dissolved and standardised in hemp seed oil. That illustrates the difference between plain hemp seed oil and hemp seed oil with CBD deliberately added to it.

See the FSA safety assessment describing CBD isolate in hemp seed oil.

So if somebody asks, “Is hemp seed oil the same as CBD oil?”, the best answer is: not by itself — but hemp seed oil can be one ingredient in a CBD oil.

How to Tell Whether an Oil Actually Contains CBD

Do not rely on the word “hemp” on the front of the bottle. Instead, check the measurable information.

• Total CBD: look for the stated amount of CBD in milligrams for the bottle.
• Bottle volume: total CBD only becomes meaningful when you also know how much liquid is in the bottle.
• CBD concentration: this may be shown as a percentage, mg/ml or both.
• Ingredient list: look for the CBD ingredient or extract and the carrier oil.
• Directions and serving information: these should let you understand the amount of CBD supplied by the product.
• Laboratory information: check what sample was actually tested and which cannabinoids were measured.

A label that simply says “1,000mg hemp oil” is not the same as saying the product contains 1,000mg CBD. The milligram figure needs to identify what it is measuring.

CBD Strength Is Not the Same as “Hemp Strength”

CBD strength should be compared using CBD concentration, not the amount of hemp-related wording on the label.

A useful calculation is:

CBD in mg/ml = total stated CBD in the bottle ÷ bottle volume in ml

For Valley CBD’s current 30ml oil range, that gives:

These are concentration figures, not recommended serving sizes. If you want a fuller explanation of percentage, total milligrams and mg/ml, see our CBD Oil Strength Guide.

Hemp Oil vs CBD Oil Price: Why the Shelf Price Can Mislead

Plain hemp seed oil and CBD oil are not like-for-like products, so comparing only the bottle price can be misleading.

If a product contains no deliberately added CBD, there is no meaningful “price per mg of CBD” to compare. For CBD oils, shoppers can compare products more fairly by looking at the total stated CBD, bottle volume and price per mg, then considering ingredients and testing information separately.

A lower-priced bottle labelled “hemp oil” is therefore not automatically a bargain alternative to CBD oil. First establish whether the bottle actually contains a declared amount of CBD.

What Should a CBD Lab Report Tell You?

Laboratory information can help clarify what a product or ingredient contains, but the scope of the report matters.

Check the sample description, batch or reference information, cannabinoid panel, units and laboratory reporting limits. Also check whether the report covers a raw ingredient or the finished consumer product. Those are not the same thing.

Terms such as “not detected” or “below LOQ” describe the result of a particular analytical method on the sample tested; they should not automatically be converted into a universal guarantee of absolute zero.

UK Rules: Hemp Seed Oil and CBD Oil Are Treated Differently

The FSA’s current guidance draws a clear regulatory line between conventional hemp-seed foods and CBD ingredients.

Hemp seeds, hemp seed oil and other established hemp-seed-derived foods are considered non-novel because there is evidence of consumption before May 1997. CBD extracts themselves, and foods to which CBD is added — including hemp seed oil with added CBD — are considered novel foods.

The FSA also makes clear that appearing on its public CBD list does not itself mean a product has been formally authorised or endorsed. This is why this guide does not describe a Valley product as “FSA approved” or use an application claim as a shortcut for product quality.

Read the FSA/GOV.UK explanation of the current CBD product list.

Can Hemp Seed Oil or CBD Oil Affect a Drug Test?

It is not responsible to give a blanket drug-test guarantee based only on a product category.

Plain hemp seed oil is not intended to supply meaningful amounts of cannabinoids, but research has detected trace cannabinoids in some commercial hemp seed oils. CBD products can also vary in their controlled-cannabinoid content depending on the extract, formulation, manufacturing and testing.

If a workplace, roadside or sporting test has serious consequences for you, check the rules that apply to that test and the actual product evidence rather than relying on phrases such as “hemp seed oil can never show up” or “THC-free guarantees a pass”.

What Type of Oil Does Valley CBD Use?

Valley CBD’s current oral CBD oils are formulated using CBD isolate with an MCT-based carrier. They are therefore CBD oils, not plain hemp seed oils.

Using isolate and MCT is a formulation choice. It does not mean that hemp seed oil is a poor food oil, nor does it mean an isolate-based CBD food is medically superior to another CBD format.

The useful distinction for a shopper is simply this: Valley’s current bottles contain a deliberately measured CBD ingredient and state their CBD concentration clearly.

Current UK FSA Guidance on CBD Intake

The Food Standards Agency currently advises healthy adults to limit CBD consumption from food to 10mg per day. This daily guidance applies regardless of whether the CBD is carried in MCT oil, hemp seed oil or another food format.

The FSA advises people under 18, those who are pregnant, breastfeeding or trying to conceive, and people taking medication to avoid CBD unless appropriately advised under medical direction.

The FSA also states that there are currently no authorised health claims for CBD food products. That is why this comparison focuses on ingredients, labelling, concentration and regulation rather than claiming that CBD oil treats pain, anxiety, poor sleep or another health condition.

Frequently Asked Questions

Is hemp oil the same as CBD oil?

Not necessarily. “Hemp oil” is ambiguous. Plain hemp seed oil is an oil made from hemp seeds, while CBD oil is deliberately formulated to contain a stated amount of CBD. Hemp seed oil can also be used as the carrier in a CBD oil.

Does hemp seed oil contain CBD?

Plain hemp seed oil is not intended as a meaningful source of CBD. However, trace cannabinoids have been detected in some commercial hemp seed oils, so an absolute “zero cannabinoids in every product” statement is not justified without product-specific evidence.

Is CBD oil made from hemp seeds?

The CBD ingredient itself is not produced by simply pressing hemp seeds. A CBD ingredient or extract is produced separately and can then be formulated into a carrier oil. That carrier can be hemp seed oil, MCT oil or another suitable food-grade oil.

Can hemp seed oil be used as a CBD carrier?

Yes. Hemp seed oil can be used as the carrier into which a measured CBD ingredient is formulated. Once CBD has been deliberately added, the finished product is no longer simply plain hemp seed oil.

Which is stronger: hemp oil or CBD oil?

The question only makes sense if “hemp oil” actually contains a stated amount of CBD. Plain hemp seed oil is not normally sold as a CBD-strength product. For CBD oils, compare total CBD, bottle volume, percentage and mg/ml.

Is hemp seed oil a novel food in the UK?

FSA guidance says hemp seed oil itself is not novel because of its established history of consumption. CBD extracts and products to which CBD is added are treated as novel foods.

Can hemp seed oil guarantee a negative drug test?

No product category should be used as an absolute drug-test guarantee. Plain hemp seed oil is not intended to contain meaningful cannabinoid levels, but trace cannabinoids have been detected in some commercial products and test policies vary.

How do I know if I am buying actual CBD oil?

Look for a clearly stated CBD amount, bottle volume, concentration, full ingredient list and appropriate laboratory information. Do not assume a large “mg” number next to the word “hemp” means the same number of milligrams of CBD.

Bottom Line: Hemp Oil vs CBD Oil UK

Plain hemp seed oil and CBD oil are different products, even though both can come from the hemp plant. Hemp seed oil is a conventional seed-derived food oil and is not intended as a meaningful source of CBD. CBD oil is deliberately formulated to contain a measurable amount of cannabidiol.

The most important detail is that hemp seed oil can also be used inside a CBD oil as the carrier. That is why the words “hemp oil” on their own are not enough.

If you are comparing CBD products, check the actual CBD milligrams, bottle volume, mg/ml or percentage, ingredient list and laboratory information. Those details tell you far more than a vague hemp-related product name.
