To be certain you’re getting test results you can trust, look for a CBD oil that’s been tested by someone other than the company selling it. Independent testing companies stake their reputations on every test, so they’re not biased toward manufacturers. These third-party testers are looking to identify what’s actually in the product, whether the manufacturer likes the results or not.
If you are vaporizing CBD-dominant strains of cannabis, bioavailability is through the alveoli, tiny sacs in the lungs, clarifies Kilham. If you are taking CBD strain capsules, he suggests eating some fat or oil, like a handful of nuts or some full-fat yogurt, to improve absorption and bioavailability. Cannabinoids are fat-loving molecules. They are taken up readily into the small intestine with a bit of dietary fat.
I would recommend always going with a full spectrum oil. Some people say to use nothing but pure 100% CBD, but if you do a little research you’ll see that most doctors will say that the full-spectrum products with terpenes etc are much more potent and effective. I would only use the CBD isolate if I was concerned about an upcoming drug test (full spectrum has trace amounts of THC in it)
“Barely in its infancy, the CBD medical market is still largely unregulated; quality control is meager at best, and consumers are largely unaware what to look for when shopping …,” explains Carlos Frias of the Texas Wellness Center. Frias, who has been with the cannabis industry for more than 15 years, has seen, firsthand, the shadiness that exists in the CBD market.
For some, having more than trace amounts of Tetrahydrocannabinol (THC) might not be a big deal, but if you’re being drug tested at work, operating heavy machinery, or fall into a number of other categories, you may want to keep the THC to a bare minimum. In order to qualify as a legal hemp product, CBD oil must contain less than 0.03% THC. Look for CBD oil certified to have low levels of, or zero, THC in them. Many reputable sellers do offer products that have absolutely no THC in them at all, so if you are concerned about keeping even trace amounts of TCH out of your body, it is best to look for those products and sellers.
