A CBD product may be broad-spectrum biocbd+ or isolate. A pure isolate has no other cannabinoids; a broad-spectrum product contains THC along with the other cannabinoids, such as CBG and CBN. Broad-spectrum products are generally more effective than isolates, due to what is called the entourage effect. However, many people prefer the taste of isolates.

The best way to buy CBD is from a company that sells products made from hemp grown domestically and third-party tested. The best brands also follow good manufacturing practices, a standard similar to the FDA’s for pharmaceuticals or dietary supplements. Look for a company that posts a certificate of analysis on its website for each batch.

CBD Dosage: Finding the Right Amount for Your Needs

Most clinical trials suggest that CBD can help relieve pain, including arthritic pain. It can also reduce anxiety, at least in small doses, although more research is needed. It can also improve sleep and decrease depression and psychosis. It has the potential to interact with certain medications, such as corticosteroids (like prednisone) and tofacitinib (Xeljanz), and may reduce the effectiveness of some antidepressants, such as amitriptyline (Elavil).

To ensure your CBD is free of contaminants and works effectively, look for a company that uses pharmaceutical-grade extraction methods. This process separates the gooey cannabinoids from other molecules, such as lipids and terpenes. Poor extractions can leave behind chemical solvents, such as butane or ethanol, which can taint the CBD with THC and can be dangerous if you’re taking prescription drugs or working in a job that conducts random drug testing.
