A crucially important factor to be acknowledged when considering this question is that most of the studies and research being performed on CBD use an isolated form of synthetic cannabidiol. Our whole plant, hemp derived CBD oil is different, and works in conjunction with the trace amounts of CBN, CBC, THC and other cannabinoids in hemp, which apparently has a dramatically more powerful effect than an isolated, synthetic form of CBD. According to seemingly competent sources, the serving size of isolated CBD far exceeds what’s needed from a whole plant CBD extract, the latter of which we carry. Also worth mentioning is that the weight of the person may play a role in how the CBD effects the body. A 40 pound child most likely won’t need the same amount as a 250 pound man to gain a similar result. There is a lot of room for experimentation with figuring out a good serving for you or your loved one. Phtyochemical constituents from hemp (like CBD) are some of the safest in the world, and there hasn’t been seen any major side effects that we’ve ever seen or heard of. So there is a lot of wiggle room in figuring out what works best for you. What’s necessary and what works may vary greatly from person to person. One last note on this topic that is absolutely worth sharing is that your body will build up a storage of cannabidiol in the body, which is unlike most chemicals. So unlike alcohol, which is usually absent from the blood stream and body within 24-48 hours after ingestion, cannabidiol can stay bound to the cells of the body for weeks. This is important to know because after a few weeks of using CBD oil a lesser amount may be required to gain effects similar to the original servings. So, the first few weeks are a prime time to have a high serving size, and you can incrementally lower the serving size over time while still having potentially equivalent results because of your body’s storage of CBD.
