What is CBD and How Does it Work?

Cannabidiol (CBD) is a naturally occurring compound found in the resinous flower of cannabis, a plant with a rich history as a medicine going back thousands of years. Today the therapeutic properties of CBD are being tested and confirmed by scientists and doctors around the world. A safe, non-addictive substance, CBD is one of more than a hundred “phytocannabinoids,” which are unique to cannabis and endow the plant with its robust therapeutic profile.

CBD is closely related to another important medicinally active phytocannabinoid: tetrahydrocannabinol (THC), the compound that causes the high that cannabis is famous for. These are the two components of cannabis that have been most studied by scientists.

The Endocannabinoid System (ECS)

The endocannabinoid system (ECS) is the body’s built-in communication network that helps regulate physiology, mood, and everyday functions. CBD supports this system by interacting with cannabinoid receptors throughout the body—including the central nervous system, immune system, and organs.There are two main receptor types: CB1 and CB2. Cannabinoids activate these receptors to trigger cellular responses that support homeostasis (balance).

  • CB1 receptors are mostly in the brain, spinal cord, and central nervous system, and influence pain sensitivity, mood, sleep, memory, and motor control.
  • CB2 receptors are mainly in the immune system and help regulate inflammation, which may reduce discomfort and support recovery from overexertion or injury.

Benefits of CBD

CBD, when applied topically, works directly where your body needs it most. Instead of circulating through the bloodstream, topical CBD interacts with receptors in the skin to help soothe localized discomfort, ease muscle tension, and calm irritated areas. Many people use CBD creams and balms to support recovery after physical activity, relieve everyday stiffness from long hours at a desk, or promote overall skin balance. Because it’s applied directly to the target area, topical CBD offers focused support without systemic effects—making it a convenient, plant-based option for daily comfort and mobility.

What are Cannabis Terpenes?

Terpenes are what you smell and taste when you handle a hemp product and understanding how they work will deepen your appreciation for cannabis. Secreted from the same glands that give us cannabinoids like CBD and THC, terpenes are aromatic oils that color cannabis strains with distinctive flavors like citrus, berry, mint and pine. Terpenes may play a key role in differentiating the effects of various cannabis strains. Some terpenes may promote relaxation and stress relief, while others could potentially boost focus and acuity.

What's the Difference

Full-spectrum CBD products contain the complete range of cannabinoids and beneficial compounds naturally found in the hemp plant, including up to 0.3% THC—the federally legal limit—which helps create the “entourage effect,” meaning the cannabinoids work together to enhance overall effectiveness; however, because they contain trace amounts of THC, there is a possibility of testing positive on a drug test. Broad-spectrum CBD products also include multiple cannabinoids and beneficial hemp compounds but are processed to contain essentially 0.00% THC, while still delivering the entourage effect. CBD isolate products, on the other hand, contain only purified CBD that has been separated from all other hemp compounds—including THC, terpenes, and waxes—resulting in cannabidiol alone; Muscle MX does not offer isolate products because we believe full- and broad-spectrum formulations that preserve the entourage effect provide the most effective benefits the hemp plant can offer.

FDA REGULATIONS ON CBD

The US Food and Drug Administration (FDA) currently prohibits all manufacturers of CBD products from making any claims about their potential to treat specific health conditions. Health claims are only permitted when approved by the FDA and based on accepted clinical trials. Because CBD is still new to the market, many clinical trials are still in process.

IS ALL CBD THE SAME

Not all CBD is created equal. With more than 3,000 CBD brands on the market, product quality can vary significantly based on hemp sourcing, extraction methods, formulation standards, and third-party testing. At Muscle MX, we prioritize premium hemp extract, advanced formulation techniques, and clean, natural ingredients to deliver high-quality CBD products you can trust. The rapid growth of the CBD industry has led to an influx of low-quality options, which is why it’s essential to look for key indicators of excellence: third-party lab testing with accessible Certificates of Analysis (COAs) verifying CBD potency, cannabinoid profile, THC compliance (under 0.3%), and purity from pesticides, heavy metals, and residual solvents; transparent ingredient lists featuring organic hemp and non-synthetic additives; and full seed-to-sale transparency outlining how the hemp is grown, extracted (such as CO₂ extraction), and formulated for maximum safety, consistency, and bioavailability. When choosing CBD for pain relief, muscle recovery, mobility support, or overall wellness, quality, compliance, and transparency make all the difference—and that’s the Muscle MX standard.

IS CBD LEGAL

Hemp-derived CBD is federally legal in the United States under the 2018 Farm Bill, which removed hemp from the list of controlled substances and reclassified it as an agricultural commodity. Hemp is legally defined as cannabis containing no more than 0.3% THC (the intoxicating compound in marijuana) on a dry-weight basis. Because CBD itself is non-intoxicating and does not produce a “high,” hemp-derived CBD products that meet this THC threshold are federally lawful. However, CBD can also be extracted from marijuana, which remains federally illegal, and individual state laws may impose additional restrictions on the sale, possession, or use of CBD products. Additionally, the FDA continues to regulate how CBD may be marketed, particularly in foods, beverages, and dietary supplements.
