CBD or CBG Isolate has no THC or other phytocannabinoids, or terpenes. Isolates are used for vaping and can be added to your food or drinks.
Many people like CBD or CBG Oil Isolate products because they have more cannabidiol or cannabigerol potency than tinctures, capsules, or edibles.
The downside is you will not get the Entourage Effect so you could be missing out on the positive therapeutic impact supplied by other cannabinoids, and terpenes.
CBD Isolates may help reduce stress, anxiety, inflammation, and muscle soreness. They can also help manage sleep and pain issues.
