Learn what the endocannabinoid system (ECS) is, how it helps regulate balance throughout the body, and how cannabinoids like CBD and THC interact with this remarkable communication network.
Editor's Note (2026):
Originally published in January 2025, this guide has been comprehensively updated to reflect the evolving CBD marketplace and Green Bee Life's commitment to consumer education.
In this refreshed edition, we've expanded the article beyond simply defining CBD products. You'll also learn how to understand CBD extracts, compare product formats, interpret common terminology found on product labels, and evaluate key educational resources such as Certificates of Analysis (COAs).
As research, regulations, and product innovation continue to evolve, our mission remains the same: to help people build the knowledge and confidence to make informed decisions for themselves and their families.
Walk into almost any health store or browse an online marketplace, and you'll quickly encounter terms like full-spectrum, broad-spectrum, CBD isolate, nano CBD, tinctures, softgels, gummies, and topicals. If you've ever wondered what those terms actually mean—or why they matter—you're not alone.
I remember feeling much the same way when I first began researching CBD products for my dog. It didn't take long to realize that understanding the terminology was just as important as understanding the product itself.
Fortunately, learning the language of CBD is easier than it may seem. Once you understand a few foundational concepts, comparing products and interpreting labels becomes much more straightforward. You'll be better equipped to read product labels, compare formulations, evaluate marketing claims, and choose products that align with your individual preferences and goals.
This guide introduces the terminology you'll encounter most often and explains how different CBD extracts, product formats, and common industry terms relate to one another. Along the way, we'll point you to additional Green Bee Life resources that explore topics such as How to Read a CBD Label Like a Pro, Certificates of Analysis (COAs), and CBD vs. THC in greater depth.
Cannabidiol (CBD) is one of more than 140 naturally occurring cannabinoids identified in the cannabis plant.1 9 While CBD and tetrahydrocannabinol (THC) are the two best-known cannabinoids, the plant also contains dozens of other naturally occurring cannabinoids—often referred to as minor cannabinoids—that continue to be studied for their unique characteristics and potential roles within the plant.
Today, hemp-derived CBD is available in a wide variety of product formats, including oils, capsules, gummies, beverages, topicals, pet products, and more. But choosing a product involves more than selecting a format—it's also important to understand what's inside that product.
CBD products can differ in the type of CBD extract they contain, the cannabinoids and other naturally occurring plant compounds they include, and the additional ingredients used to create the final formulation. Some products contain only CBD, while others combine CBD with cannabinoids such as CBG or CBN, botanical ingredients like lavender or valerian root, or other functional ingredients intended for specific uses.
Understanding these differences is one of the keys to comparing CBD products with confidence—and that's exactly what we'll explore throughout this guide.
If you're new to CBD—or simply looking for a deeper understanding—we recommend starting with our foundational guide, What Is CBD? There, you'll learn how CBD differs from THC, how it interacts with the body's endocannabinoid system (ECS),1 and what current research does—and does not—tell us.
products contain the same type of CBD extract. Understanding what those extracts are—and how they differ—can make it much easier to interpret product labels, compare formulations, and choose products with confidence.
In this context, an extract refers to the collection of naturally occurring compounds that remain after cannabinoids and other plant constituents are extracted from hemp.
Understanding the three primary CBD extract types can help you interpret product labels, compare formulations, and better understand what's inside the products you're considering.
Full-spectrum CBD contains CBD along with the full range of naturally occurring compounds found in the hemp plant, including minor cannabinoids, terpenes, flavonoids, and trace amounts of THC (within the legal limit for hemp-derived products in the United States). 3
Because these compounds remain together, full-spectrum CBD provides the broadest representation of the hemp plant's naturally occurring cannabinoids, terpenes, flavonoids, and other beneficial plant compounds. Many people choose full-spectrum products because they prefer a more complete, whole-plant extract and are interested in what is known as the entourage effect—the idea that naturally occurring cannabinoids, terpenes, flavonoids, and other plant compounds may interact differently together than they do individually.7 While research continues to explore these interactions, many consumers and practitioners consider the entourage effect an important reason to choose full-spectrum products.
Broad-spectrum CBD also contains CBD along with a variety of other cannabinoids and naturally occurring plant compounds, but it is processed to remove THC. This option appeals to people who want a broader cannabinoid profile while avoiding THC.
CBD isolate is the most refined form of CBD, containing only cannabidiol (CBD). During processing, the other naturally occurring cannabinoids, terpenes, flavonoids, and plant compounds are removed, resulting in a purified extract that contains CBD alone.
The comparison below summarizes the primary differences between the three most common CBD extract types.
If you've spent time researching CBD, you've probably come across the term entourage effect. It describes the theory that cannabinoids, terpenes, flavonoids, and other naturally occurring compounds in the cannabis plant may interact differently when present together than when used individually. 7
Researchers continue to study this concept, and while scientific interest remains high, our understanding of the entourage effect continues to evolve. For many people, however, it remains one of the factors they consider when choosing between full-spectrum, broad-spectrum, and CBD isolate products.

Think of it this way: Imagine listening to a single violin. It's beautiful on its own. Now imagine hearing a jazz trio, where each instrument adds depth and harmony. Finally, imagine a full orchestra, where dozens of instruments contribute to a richer, more complex performance. While no analogy is perfect, some people think of CBD isolate, broad-spectrum CBD, and full-spectrum CBD in a similar way. The more naturally occurring plant compounds that remain together, the more complex the overall composition becomes.
In addition to the three primary extract types, you may also see products labeled Nano CBD, Nano-Optimized CBD, or Nanoemulsified CBD.
Unlike full-spectrum, broad-spectrum, or CBD isolate, Nano CBD is not a different type of CBD extract. Instead, it refers to CBD that has undergone an additional manufacturing process called nanoemulsification, which reduces CBD particles into much smaller droplets.
Because CBD is naturally oil-soluble rather than water-soluble, it can be difficult to incorporate into beverages and other water-based products. Nanoemulsification allows CBD to disperse more evenly in water, making it especially useful in products such as CBD-infused drinks, drink mixes, and other liquid formulations.
Research suggests that nanoemulsion technology can improve the bioavailability of CBD by increasing its dispersion and absorption compared with conventional formulations.8 As a result, Nano CBD products may have a faster onset of action or require smaller serving sizes to achieve similar results, although individual responses and product formulations can vary.

Once you understand the different types of CBD extracts, the next step is choosing a product format that best fits your lifestyle, preferences, and intended use. While the extract determines what's in the product, the product format determines how you choose to use it.
Today, CBD products are available in a wide variety of formats for both people and companion animals. While oils, gummies, capsules, and topicals remain among the most common, manufacturers continue to introduce new ways to incorporate CBD into everyday wellness routines.
Many of these product formats are available as full-spectrum, broad-spectrum, or CBD isolate formulations. In other words, the product format and the type of extract are separate characteristics that work together to define the final product.
One of the most versatile CBD formats. Oils and tinctures are commonly taken under the tongue or added to food and beverages.

You'll also find CBD in products such as powders, honey, chocolates, bath products, and other specialty formulations as the marketplace continues to evolve.
As the CBD marketplace continues to evolve, new delivery formats will likely emerge, but understanding the difference between the extract and the product format will make it easier to evaluate future products as well.
As you compare CBD products and read product labels, you'll likely encounter the following terms. Here's a quick reference to some of the most common.
