Full spectrum vs broad spectrum vs isolate
Full spectrum, broad spectrum and isolate are the three central CBD types — they differ in cannabinoid profile, THC content, taste and entourage effect. Which type belongs in which product line, what the choice means for compliance, and what to watch when buying wholesale: this B2B comparison sets it out.
The three CBD types at a glance
CBD can be produced from the hemp plant in three fundamentally different spectra. The difference lies not in the CBD itself but in which other plant compounds remain in the finished product. Full spectrum preserves the complete natural profile including traces of THC, broad spectrum removes the THC specifically, and isolate reduces everything to pure CBD. That single decision affects THCcompliance, taste, dosing accuracy and target market.
| Criterion | Full spectrum | Broad spectrum | Isolate |
|---|---|---|---|
| Cannabinoids present | all natural cannabinoids (CBD, CBG, CBN and others) | a wide cannabinoid profile, but THC removed | CBD only, no further cannabinoids |
| THC content | traces below the limit (usually 0.2 to 0.3%) | no detectable THC | free of THC (around 99% pure CBD) |
| Terpenes / entourage effect | fully preserved, strongest entourage effect | largely preserved, entourage effect without THC | no terpenes, no entourage effect |
| Taste / smell | strong, typically hempy, earthy | mildly vegetal, subdued | neutral, free of taste and smell |
| Drug-test risk | low, though THC is detectable in principle | very low (no detectable THC) | practically none |
| Ideal audience / use case | natural positioning, premium oils | THC-sensitive markets wanting a full profile | precise formulations, cosmetics, food |
Compact definitions are also in the glossary, under full spectrum, broad spectrum and isolate.
Full spectrum: the complete plant profile
Full-spectrum CBD contains the hemp plant's entire natural range of active compounds: besides CBD also minor cannabinoids such as CBG and CBN, plus terpenes and flavonoids — and traces of THC. It is precisely this complete profile that underlies the entourage effect, the synergistic interplay of the plant compounds.
Full-spectrum goods are obtained gently, by CO2 extraction, for instance, and often processed further into a cannabinoid-rich distillate The typically hempy, earthy taste is characteristic and, for many end customers, a mark of naturalness. Because full spectrum carries traces of THC, it remains EU-compliant only where the finished product stays below the applicable THC limit — evidenced by a current certificate of analysis.
Strength: the strongest entourage effect and a credible natural positioning. Limit: traces of THC are present in the finished product and can in principle be detected in sensitive drug tests.
Broad spectrum: a wide profile without THC
Broad-spectrum CBD is the middle course: it preserves the wide cannabinoid and terpene profile of full spectrum, but goes through an additional processing step in which the THC is removed specifically. The result is a product without detectable THC that still benefits from a reduced entourage effect.
For many B2B applications that is ideal: broad spectrum suits THC-sensitive markets and audiences that require a THC-free profile without giving up the variety of plant compounds entirely. In taste it is milder than full spectrum but keeps a slightly vegetal note. Here too the actual profile is set out by the COA for the batch.
THC removed
No detectable THC, with the cannabinoid profile preserved.
Entourage preserved
Terpenes and minor cannabinoids largely remain.
Market flexibility
Suitable for THC-sensitive target markets and product lines.
Isolate: pure CBD, dosable exactly
CBD isolate is the purest form: around 99% crystalline CBD, obtained by purifying the extract further until all other cannabinoids, terpenes and flavonoids are gone. It therefore contains no THC and triggers no entourage effect — but it is neutral in taste and smell and can be dosed to the milligram.
This neutrality makes isolate the most versatile raw material for own brands: it disappears into any formulation in terms of flavour and delivers CBD quantities that can be declared exactly. That makes it the first choice for precise formulations, THC-free requirements and applications where a hemp taste would get in the way. More on the definition in the isolate entry in the glossary.
In short: isolate sacrifices the entourage effect in favour of maximum purity, dosing accuracy and neutrality — ideal for isolates as a raw material and for white label formulations.
The entourage effect
The entourage effect describes the idea that cannabinoids and terpenes acting together can behave differently from a single isolated substance. Several plant compounds, on this view, complement one another as an overall matrix. This interplay is relevant only for full and broad spectrum, since only these types bring a wide profile with them — isolate by definition contains no further cannabinoids or terpenes and therefore cannot trigger an entourage effect.
Important for retailers: The entourage effect is a neutral concept and must not be communicated as a therapeutic promise. Disease-related health claims are not permitted. Stay with factual, product-related statements and refer to the certificate of analysis.

Which type for which product?
The choice of spectrum depends on product type, target market and compliance requirements. A rough guide for the most common product lines:
Oils and tinctures
Full spectrum for a natural positioning, broad spectrum for THC-free markets.
Flowers
Full-spectrum character — typically hempy aroma and the complete profile.
Cosmetics
Isolate or broad spectrum — neutral, easy to formulate, free of THC.
Food
Isolate for exact dosing; observe the novel food status for products taken orally.
Rule of thumb: where a natural story and the maximum entourage effect matter, the route leads to full spectrum. Where a THC-free profile comes first, broad spectrum is the answer. Where purity, exact dosing and neutral taste count, isolate is settled. In every case the product category determines the regulatory obligations.
Buying wholesale
In B2B purchasing it is not the label that counts but the evidence: which spectrum type is actually delivered is established by the certificate of analysis (COA) for the batch — including the cannabinoid profile and the THC value. Look additionally for standardised production under GMP and a gentle CO2 extraction.
COA per batch
The cannabinoid profile and THC value evidence the spectrum type delivered.
