The best CBD oils, reviewed

What to look for

When choosing a CBD oil, weigh these factors:

• CBD type: Full-spectrum includes trace THC and the entourage effect; broad-spectrum removes THC; isolate is pure CBD.
• Third-party testing: Only buy oils with a current, batch-matched COA confirming potency and screening for contaminants.
• Potency and price per mg: Compare cost per milligram, not per bottle, and match the strength to your experience level.
• Ingredients: Look for organic hemp and a short, clean ingredient list; carrier oils like MCT or hempseed are common.
• How to dose: Hold the oil under your tongue for 60 seconds before swallowing for faster, more efficient absorption.

Safety and considerations

CBD is generally well tolerated, with possible side effects including drowsiness, dry mouth, and digestive upset. It can interact with some medications, notably blood thinners, so talk to your doctor before starting — especially if pregnant, nursing, or on prescription drugs. Full-spectrum oils contain trace THC that could affect a drug test.

Frequently asked questions

What is the best CBD oil?

Our top overall pick is Cornbread Hemp for its organic, flower-only quality, with Lazarus Naturals the best value and Medterra the best THC-free option.

How do I take CBD oil?

Place your dose under the tongue and hold for about 60 seconds before swallowing for faster absorption. Start low and adjust after a week.

Will CBD oil show up on a drug test?

Full-spectrum oils contain trace THC that can, in rare cases, trigger a positive test. Choose broad-spectrum or isolate if you’re tested.

How much CBD oil should I take?

Start with a low dose (e.g., 10–15mg) and increase gradually over a week or two based on how you feel.

The bottom line

The best CBD oil depends on what you value: Cornbread Hemp for organic quality, Lazarus Naturals for value, Five CBD for potency, and Medterra for reliable THC-free options. Whichever you choose, buy from a brand that publishes current lab results, and start with a low dose under the tongue.
