CBD Oil Buyer's Guide: What to Check Before You Buy

Shopping for CBD oil shouldn't require a chemistry degree. Here's the short checklist we wish every buyer had.

1. Demand a third-party lab report (COA)

This is the single most important thing. A certificate of analysis from an independent lab — not the brand's own claims — should verify what's in the bottle. If a company won't publish COAs, or only shows a lab report for their raw ingredient instead of the finished product, walk away.

2. Check the THC content

Hemp-derived CBD products must contain less than 0.3% THC to be federally compliant. The COA should show the exact THC figure. "THC-free" broad-spectrum products should show non-detectable THC levels.

3. Read the actual ingredient list

A clean tincture needs very few ingredients: hemp extract and a carrier oil (often organic MCT coconut oil). Long lists of flavorings, sweeteners, and fillers are a sign of a product built for marketing, not quality.

4. Do the strength math

The big number on the front (500mg, 1000mg) is the total CBD in the bottle — not per dropper. A 1000mg bottle at 30ml gives you about 33mg per 1ml dropper. Our strengths guide walks through the math.

5. Watch for red-flag claims

The FDA prohibits CBD brands from claiming their products diagnose, treat, cure, or prevent any disease — and has sent warning letters to companies that do. If a brand promises miracle cures, that's not confidence-inspiring marketing; it's a compliance violation. Buy from companies that stay in their lane.

6. Compare price per mg, not per bottle

A $40 bottle with 500mg ($0.08/mg) is a worse deal than a $60 bottle with 1000mg ($0.06/mg). Divide price by total milligrams to compare honestly across brands.
