CBD 101: Full-Spectrum vs. Broad-Spectrum vs. Isolate — Which Is Right for You?
CBD products generally fall into three categories. Full-spectrum contains the full range of hemp compounds including trace THC (legally under 0.3% under the 2018 Farm Bill); broad-spectrum keeps most compounds but removes THC; and isolate is purified CBD alone. The so-called "entourage effect" — the idea that cannabinoids and terpenes may work better together — is a plausible hypothesis but remains scientifically unproven, so it should be treated as a marketing concept rather than an established fact.
A reputable certificate of analysis (COA) from an independent, accredited lab is one of the most useful tools for shoppers. It confirms cannabinoid content and screens for contaminants such as pesticides, heavy metals, and residual solvents. Because the FDA does not approve or verify most CBD products and quality varies widely across the market, checking a current COA that matches your product's batch is worthwhile before you buy.
Aside from one prescription CBD medication approved for specific seizure disorders, CBD products are not FDA-approved to diagnose, treat, cure, or prevent any disease. CBD can interact with medications and affect the liver, so consult a licensed healthcare provider before use, especially if you are pregnant, nursing, or taking other drugs.
