CBD Isolate is the purest supplement available. It’s a 99% pure CBD supplement derived from hemp oil. Despite its concentration, CBD isolate effects are similar to other CBD concentrates, and it can be used in a variety of ways. It can be consumed itself, added to foods and beverages, or vaporized. You can also add it to other CBD products to increase their potency.
CBD has proven neuroprotective effects and its anti-cancer properties are being investigated at several academic research centers in the United States and elsewhere. A 2010 brain cancer study by California scientists found that CBD “enhances the inhibitory effects of THC on human glioblastoma cell proliferation and survival.” This means that CBD makes THC even more potent as an anticancer substance. Also in 2010, German researchers reported that CBD stimulates neurogenesis, the growth of new brain cells, in adult mammals.
Because of recent legislation legalizing marijuana, CBD product sales have grown. People are more open to the medical benefits of the drug, especially now that CBD can be separated from THC. With popularity and interest on the rise, manufacturers have expanded their product offerings. Products typically come in two types: nutritional or medicinal products and beauty products.
First you need to realize that there are more than 70 different cannabinoids that have been identified so far and over 500 constituents of cannabis including various terpenoids and flavonoids. In fact, the US government holds multiple patents on various cannabinoids. They also hold patents defining these cannabinoids many medical benefits.  One of these cannabinoids which has shown a huge amount of potential is CBD or Cannabidiol and while its potential could not possibly be understated there is another cannabinoid making headlines as well. Tetrahydrocannabidiol otherwise known as THC.
Isolate CBD is the CBD gets its extraction from the cannabis plant without other terpenes and cannabinoids. Many users of this CBD type consider this much better than the full spectrum. They go as far enough to get this type of CBD by isolating the CBD from others themselves. They are even different dosage methods and levels for each kind of CBDs and therefore should carefully be in separation for each of the CBD types.

So which is better? Hemp derived CBD or Medical marijuana derived CBD?  I believe, given the information I have found, that the reasonable and definitive question we should ask is: What are the pros and cons of both options and, most of all, what will be best for me and fit my lifestyle. In addition, legality within the state and country you live must be taken into consideration. 
Full spectrum CBD also contains a variety of essential vitamins, minerals, fatty acids, protein, chlorophyll, terpenes, flavonoids, and fiber. When referring to CBD in the hemp plant, it’s important to understand that hemp contains a large number of cannabinoids (in trace amounts), but the main compound is cannabidiolic acid (CBDa). As CBDa is more abundant in the hemp plant, firms must decarboxylate the oil. This process heats the oil and changes CBDa into CBD.
Under federal law, cannabis (from which both CBD and marijuana are derived) is illegal everywhere, although the laws against it aren’t generally enforced in states that have legalized marijuana. Some manufacturers claim that CBD culled from legally imported industrial hemp, which has little to no THC, is fine to ship across the U.S., but many experts disagree, noting that because hemp comes from the same species as marijuana, cannabis sativa, all CBD falls under the DEA’s Schedule 1 designation. “This creative interpretation of the law runs afoul of reality,” says the Brookings Institution, a Washington, DC, think tank.
Success stories like Oliver’s are everywhere, but there’s not a lot of data to back up those results. That’s because CBD comes from cannabis and, like nearly all other parts of the plant, is categorized by the Drug Enforcement Agency (DEA) as a Schedule 1 drug—the most restrictive classification. (Others on that list: heroin, Ecstasy, and peyote.) This classification, which cannabis advocates have tried for years to change, keeps cannabis-derived products, including CBD, from being properly studied in the U.S.
Because the FDA considers CO2 extraction to be GRAS or “generally regarded as safe” for commercial extraction, this method is popular in the food industry. The stability of supercritical CO2 also allows most compounds to be extracted with little damage. In the coffee industry, supercritical CO2 is already widely accepted as safer than traditional solvents to extract the caffeine from decaffeinated coffee beans.

By formulating our products with pure, full-spectrum hemp oil, we ensure that all the cannabinoids naturally found in the plant are in the hemp oil you buy from us. This also allows the cannabinoids to interact with the endocannabinoid system in what has become known as the entourage effect: when all the ingredients in hemp oil, including the terpenes, vitamins, and range of cannabinoids are allowed to work with the body naturally, as they would in the natural plant.
As the oil is in liquid form it can be consumed orally without smoking and can be easily administered to ailing children and adults for whom it is prescribed as medication. Though hemp plant is used for several industrial products and also as biofuel, the seeds and flowers of the plant are used to produce oil that is an active ingredient in several medical therapies for humans and animals.

At least one benefit of CBD is well-supported by science: It can be effective in treating children with rare, genetic seizure disorders. Adults, children and even animals with epilepsy have been shown to benefit from the chemical too, the World Health Organization reports. There's also some evidence that CBD can help with anxiety, says Dr. Robert Carson, an assistant professor of neurology and pediatrics at Vanderbilt University who focuses on children with epilepsy. "In children, especially those with autism spectrum disorders, this may manifest as improved interactions with others," he says. Other preliminary research shows CBD holds promise for conditions including Alzheimer's disease, cancer, psychosis and Parkinson's disease – and is pretty much impossible to abuse or become addicted to, WHO says.
Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.
For applications where pure CBD isn’t required, full spectrum CBD oil is the better alternative, as it provides patients the ancillary benefits associated with the many other cannabis compounds. However, important to note, is the issue of what medical conditions are best treated by either pure or full spectrum CBD oil, given the research is in its infancy. 
Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
'If you have a health condition, or are taking any prescribed or over-the-counter medicines, always check with your doctor or a pharmacist for possible drug supplement interactions before taking CBD,' says Dr Brewer. 'This is because CBD interacts with enzymes involved in metabolising some medicines and may result in increased drug levels that could cause side effects.
Herrera and her patients aren't the only ones doling out rave reviews for CBD oil, which can be found online and in cannabis dispensaries, as well as in some grocery stores and even as an optional add-in alongside protein powder at your local juice chain. The oil has been riding the coattails of the growing legal cannabis industry, with one industry expert, Matt Karnes, telling Forbes in 2016 that he expected CBD products to become an almost $3 billion market by 2021.
