These names describe what is in the extract. Broad spectrum keeps multiple hemp compounds while removing THC during processing; full spectrum includes THC; isolate separates CBD from the other compounds. The lab report tells you what was measured.
Extracts, explained
Three profiles. A clearer decision.
| What matters | Broad spectrum | Full spectrum | Isolate |
|---|---|---|---|
| Extract profile | CBD with other hemp compounds; THC is removed during processing. | CBD with other hemp compounds, including THC. | CBD separated from the other hemp compounds. |
| Why choose it? | A multi-compound extract with THC removed during processing. | A person may specifically want a THC-containing extract. | A person may prefer a CBD-only ingredient. |
| What to verify | Lot-specific THC result and the test’s detection limit. | Measured THC amount, serving size and applicable rules. | CBD purity, other ingredients and contamination tests. |
| Our choice | The format we choose for our CBD oil range. | Not the extract type of our CBD oils. | A CBD-only extract for people who prefer a single cannabinoid. |
A spectrum name is the starting point.
Find the right sample
Match the product name and lot code. An old report for a different lot does not certify the bottle in your hand.
Read the THC result
“ND” means not detected under that test’s detection limit. It is not a universal zero, and it is not a promise about a drug test.
Look beyond cannabinoids
Potency and safety panels answer different questions. Read which contaminants were actually tested and the reported result.
Make it practical
Our broad-spectrum choice.
We choose broad spectrum for a multi-compound hemp extract with THC removed during processing. It is a straightforward fit for our Calm, Peace and Sleep oil range.
A good report lets you check the THC result and other tested compounds. Your priorities, the ingredients and the measured results can guide the choice.
What about the “entourage effect”?
The idea is that cannabis compounds may work together. It is a research question, not a shortcut to proving a retail bottle works better. Human outcomes depend on the formulation, amount, person and outcome studied.
For shopping, put identifiable ingredients and an actual report ahead of a broad superiority claim. See our product and editorial standards.

Calm. Peace. Sleep. Compare the three oils.
Three concentrations. The same 30 mL bottle size. Compare the amount you measure, not just the number on the front.
Calm
500 mg CBD oil
16.7 mg CBD per mL · 30 mL
Single bottle
$34.00
$6.80 per 100 mg CBD
Peace
1,000 mg CBD oil
33.3 mg CBD per mL · 30 mL
Single bottle
$59.00
$5.90 per 100 mg CBD
Sleep
3,000 mg CBD oil
100 mg CBD per mL · 30 mL
Single bottle
$124.00
$4.13 per 100 mg CBD
Calm, Peace and Sleep describe our routine choices. They are not different medical treatments, and a higher concentration does not guarantee a stronger effect.
Your questions
A few useful answers.
Is broad spectrum THC-free?
It is processed to remove THC. Use the actual lot result and detection limit to understand a particular sample; the spectrum name alone is not enough.
Does full spectrum always make someone feel high?
Effects depend on the actual THC amount, serving, person and other factors. Read the measured THC result rather than assuming an effect from the label term.
Can isolate work?
CBD itself has been studied, including purified prescription formulations. That does not establish the effect of every retail isolate product, but it also does not justify calling isolate ineffective.
