Quick Answer
Nano pearls are small, round CBD doses. Most measure 5 mm to 10 mm across. They look like softgels or beads. Each pearl carries a set amount of CBD, with common ranges from 5 mg to 25 mg. The word "nano" describes the oil droplets inside, not the pearl size. Makers break CBD oil into droplets of 20 nm to 200 nm, then set the mix in a shell.
How Makers Build a Pearl
- Mix CBD with a carrier oil and an emulsifier.
- Push the mix through a high-pressure homogenizer.
- Coat the emulsion in gelatin, starch, or a plant gum.
- Dry the pearls and test the batch.
Droplet size drives the label claim. A 100 nm droplet has more surface area than a 5,000 nm droplet of the same weight.
Absorption and Bioavailability
Swallowed CBD oil absorbs at low rates. The National Institutes of Health reports poor and variable oral bioavailability for CBD. Published nanoemulsion trials report higher peak plasma levels than oil controls. Sample sizes are small, often under 30 people. No standard dose exists.
How to Choose the Best Pearl Jewelry for Your CBD Store
What the Label Should Show
- Milligrams of CBD per pearl
- Number of pearls per bottle
- Total CBD in the package
- Carrier oil and emulsifier names
- Batch or lot number
- Expiration date
COA Checks
Ask for a certificate of analysis from the batch on your bottle. The COA should list cannabinoid potency, residual solvents, pesticides, heavy metals, and microbials. Match the batch number on the COA to the batch number on the label. Check the lab name and test date. A result of 0.9 mg in a pearl sold as 1 mg falls inside normal lab variance.
Storage
Keep pearls in the original bottle. Heat and light degrade cannabinoids. Gelatin shells soften in humid air and stick together. A drawer at 60 F to 77 F works. Do not freeze softgels.
Legal Status
The FDA has not approved CBD for use in food or dietary supplements. One CBD drug, Epidiolex, holds FDA approval for seizures. Hemp-derived CBD with less than 0.3% THC is legal under the 2018 Farm Bill. State rules differ.
Open Questions
Long-term safety data are thin. Researchers have not set a standard dose. Nano-scale particles raise questions about tissue distribution that studies have not answered. Talk to a clinician before use if you take other medicines. CBD can change how the liver breaks down some drugs.
