CBD Hemp Oil: What To Know Before You Buy

Cannabidiol (CBD) is improving the lives of people and making life more enjoyable for those who use it.  These positive results are reflected in online forums as well as research.  

With the emerging market, and the legality of Hemp CBD across the US, the question becomes…Which companies are the best? Which ones are affordable?  How do I know which is a reputable company?  How do I know if their product is of high quality.  What does the MG on the bottle mean?  What dose do I begin with? (See how we rated each company in the tables below.)

It really is a personal decision by each person.  Some people, like myself, prefer a brand that guarantees ZERO THC, while others prefer a brand that is grown exclusively in the US.  Others will prefer a brand that promotes social conscience, proactively helps children who are sick and provides financial assistance to those in need.

The CBD Oil industry is relatively new and therefore is unregulated.  Without regulations there is very little standardization of terms when looking for a quality oil.  The terms vary from the ingredients, to the measurements, to the description, which makes it very confusing when shopping.

Before we start looking at each brand or company, let’s look at some of the research related to ADHD.

Is It Legal?

Hemp and Marijuana are similar because they both have CBD in their genetic makeup.  However, hemp has very little or only trace amounts of THC, which is the component that creates the “high” effect.

The Federal Government has established limits on legal content of THC.  The law states any product with less than 0.3% THC is legal in the United States

This means CBD Hemp Oil is legal in all fifty states. However, CBD derived from cannabis/medical marijuana is only legal in designated states. And some states have laws preventing CBD Hemp companies from shipping to their state.  Always check the fine print.

Is It Full Spectrum?

What are the ingredients?  Full Spectrum, Phytocannabinoid Rich (PCR) and Whole Plant are all the same thing.  They mean the CBD comes from all parts of the hemp plant (not just one, such as only the stalk, only the seed, only the leaves or only the flower).

Cannabinoids – CBD has many different strains and variations which provide more benefits as a whole, than any single cannabinoid alone.  In order to gain all the benefits of CBD oil, it should be full Spectrum (or Phytocannabinoid Rich, or Whole Plant).  However, if you choose to avoid all THC, you can opt for an CBD Isolate, which only includes CBD (Without other cannabinoids, including THC).

CBD Oil vs Hemp Seed Oil – There is very little to no CBD in Hemp seeds, therefore there is no benefits of CBD in hemp seed oil.  However, the seeds providenutritional value as a food source, but no value as CBD.  The process of extracting CBD from the hemp plant is more expensive and complex than extracting the oil from hemp seeds.  Hemp Seed Oil can be purchased at the grocery store or Amazon for a fraction of the price of CBD oil because it costs considerably less to extract the oil from the seeds.


Because the CBD oil industry is not regulated, there is no standardization of measurement.

Bottled CBD oils come in ounces (oz), grams (g), and milliliters (ML).  Potency (or strength) is measured in milligrams (MG) and comes PER bottle.  The bottles range from 1oz, 4oz, 15 ML, or 30 ML and more.  Since they are measured differently, how does a person compare and contrast them?

1000 MG Bottle = 500 MG Bottle

Just because a bottle reflects a high potency does not mean it is stronger than a lower potency bottle.

1000 MG CBD in 30 ML bottle has the same potency as a 500 MG CBD in 15 ML bottle.

1000 MG/30 ML = 33.33 MG of CBD per 1 ML of oil

500 MG/15 ML = 33.33 MG of CBD per 1 ML of oil.

How To Find The Exact Potency To Compare to Other Oils

The first thing you should do is convert every bottle’s measurement to CBD MG/ML

Step 1 –  find the total CBD MG on the bottle and the total ML of liquid in the bottle. (You may need to convert bottle size to ML.)

Step 2 – Divide the MG by the ML to get the amount of CBD per each ML (CBD MG/ML).

Extraction Process

CO2 extraction – This method does not require heat or solvents, and the entire spectrum of cannabinoids are retained in the blend. It is an expensive process but considered to the a cleanest process.

CO2 extraction is a process that requires skill to perform correctly, and it’s a more costly process than others, but it’s the safest method there is and it produces the highest quality products. It’s an environmentally safe element, and it’s recyclable. CO2 extraction processes don’t contribute to carbon emission increases in the atmosphere, and this process doesn’t bring any flammable petroleum based solvents (like butane) into contact with your product.

Ethanol/Alcohol Extraction – the most historically used method for cannabis/hemp extracts. It is a clean and cold extraction method that allows for optimal retention of terpenes and other sensitive compounds.

Other Factors to Consider

Founded:  How long has the company been operating?  There is experience associated with a company that has been operating since the beginning of this emerging industry.

Guarantee vs Return/Refund Policy

There is value to a Satisfaction Guarantee.  Many of these oils are expensive because of the extraction process and the cost of doing business.  If the oil does not work for you, because every individual is different, it’s less stressful to know you can get your money back if it’s not a good fit.

“Satisfaction Guarantee” is defined as – an opened and used product can be returned to the company for a refund within a set period of time.

Return/Refund Policy – The product must be unopened and in new condition to receive a refund within a set period of time.

Organic/NonGMO:   All, except two of the companies are using Organic farming practices to source their Hemp.  The remaining two companies are considered NonGMO.

Third Party Lab Tested:  All the companies listed say they are tested by independent third party labs to insure a clean Hemp product.  A company that provides batch test results is going one more step to prove the value of their oil and is considered transparent to their customers.

Sourced:  Where is the Hemp grown?  I’m very much on the fence with this one.  I love that hemp is sourced in the US, because I’m a bit patriotic and I love my country and I want to support locally grown crops.  However, Europe is more forward thinking in terms of organic farming practices by banning toxic chemicals and substances the US still uses.  European grown hemp may be cleaner than American grown.  But here’s the flip side….In my research I found that some European growers may actually obtain their crop from China which is not known for organic farming practices.

“Zero THC” Products:  There are several companies that market products which include ZERO THC (the substance that creates a “high” in cannabis) such as HempMeds, HempWorx, FarmaceuticalCBD and Green Roads.  The US federal government has set a  max of 0.3% THC a product can have to be legal in the states.  So every CBD Hemp Oil product sold online, without a prescription, has 0.3% THC or less.

The stars were applied based on each of the following categories.  Founded 2014 or earlier, Satisfaction Guarantee, Organic, Independent Lab tested, Financial Assistance Program, Full Spectrum, and CO2 Extraction, and provide batch lab results to customers.   1 star (⭐️) per category if applicable.

Rule Of Thumb

The most important thing to remember is to always start at a very, very low dose so the body can adjust.  Slowly increase your dosage over time until you see your desired results.  Every person and body is different, so do not try to compare your dose to someone else.

Pros:  NuLeaf ships internationally thru it’s website without any red-tape.  They ship to the European Union, Switzerland, China, Japan, Australia, Mexico, Canada, and more.  I love that they offer pet oils as well.  They use organic farming practices, no artificial ingredients added, just pure CBD oil.  Their oil is full spectrum.

Cons:  Not much variety in products or potency.  NuLeaf only offers one potency of 50 mg/1 ml.  The only variety is the size of the bottle.


Pros:  Lots of variety in products, including skincare, Zero THC products, various potency levels.  Hemp meds is a full spectrum oil, sourced in Europe.

Cons:  They are NonGMO instead of organic.  HempMeds only ships to the US.


Pros:  Affordable options with various potency levels. They offer a 90 Day Satisfaction Guarantee so you can return the bottle if you don’t see any benefit. Hemp sourced in Denmark.

Cons:  No variety of products. Relatively new company that was founded in 2016.

Diamond CBD:

Pros:  Large variety of potency and CBD products including gummies, candy and even Cake Pops and Honey Sticks.  Also promotes pet products infused with CBD.

Cons:  New company founded in 2017. Could not find on website if Diamond CBD is a full spectrum oil.

Farmaceutical CBD:

Pros:  Large variety of products including gummies, capsules and lipbalm as well as oil.  I love the samples of almost everything that is affordably priced for consumers to try.

Cons:  Relatively new company founded in 2017.  Not using CO2 Extraction.

Bluebird Botanicals:

Pros:  Longevity in the market – founded in 2012.  Large variety of products including pet products. Uses organic farming practices.  Affordable prices.  Offers Financial Assistance programs to the disabled, low-income and/or US veterans. Provides Lab Results per batch on website.

Cons:  Does not ship to South Dakota and no “Satisfaction Guarantee”.  Does not use CO2 Extraction.


Pros:  Large variety of products.  Offers “Zero THC” products.

Cons:  It’s a Multi-Level-Marketing Company, founded in 2017, and new to the CBD market.  Users can not order from website unless they have a reference name.  Very little information is included on the website and what is there seems inaccurate, contradicting and/or confusing.  The legal limit of THC is 0.3%, not .03%.  It’s unclear if HempWorx uses supercritical, sub-critical, or CO2 Total extraction, but it’s CO2, at least. In the FAQ regarding Hemp Seed Oil vs High CBD Hemp extracts (not from seed), seems to contradict the ingredient label which reflects “PCR Hemp (Seed) Oil”, since the contents and descriptions are not standardized across brands, this could simply be a unclear description issue. The Satisfaction Guarantee is 30 Days from Order date, not the date you receive, so if it takes two weeks to ship, you only have two weeks to find beneficial dose, which is not enough time.  I’ve heard numerous complaints regarding harassment from the company to sell, sell, sell, once you buy.  Probably best to just avoid this company.

Charlotte’s Web (CWHemp):

Pros:  This company has been around since the beginning.  They catapulted CBD oil into the spotlight by helping improve the life of Charlotte.  CW Hemp has a 30 day Satisfaction Guarantee and was founded in 2011.  Offers pet products. Provide Lab Results per batch upon request.

Cons:  The raw hemp they harvest is not organic.  There is almost no information on the website regarding how the hemp is extracted, where or how it’s grown (Colorado), when the company was founded, or if the oil is a full spectrum oil.

Haleigh’s Hope:

Pros:  Utilizes organic farming practices.  Has longevity in the market since founded in 2012.  Offers Low Income Assistance Program.

Cons:  Cannot determine from website if oil is full spectrum.  The potency is listed as a ratio of CBD to THC (20:1), without a disclosure of potency per MG.  Can not convert to a MG/ML unit.

Green Roads:

Pros:  Green Roads practices organic farming practices and  the only brand that promotes a full spectrum oil plus a pure crystalline isolate 99% to create an entourage effect.  The company was founded in 2011, therefore has lots of longevity in the market. Provides lab reports online, but not per batch.

Cons:  Does not ship internationally.
