2. Verma Farms
One of the top brands in CBD out, Verma Farms has been winning awards left and right for the past couple of years, with 2021 as no exception.
What Verma does well provides a solution that helps set the standard for how CBD oils should go. Starting out with very intent-driven oils like Focus, Chill, and Boost, they began diversifying their lineup to include more fruit-flavored varieties as well, such as Lemon Lime, Pineapple, Strawberry, Watermelon, Mango, and Peach. As all of them use natural, vegan ingredients, they’ve stripped down their offering to host only the standards but doing it well, sourcing all their oil’s materials from inside the US.
An overall great brand, Verma Farms is an easy number one for any CBD fan out there, no matter how much they’ve done.
3. BATCH CBD
BATCH brings something to the CBD industry that few other brands offer: radical transparency. From local home-state hemp sourcing, virtual or in-person facility tours, and easily scannable lab results printed on every product, BATCH ensures you’re getting exactly what you pay for.

Sustainability is also a key focus for BATCH. Their motto, Loyal to the Soil, means choosing eco-friendly packaging, recyclable shipping materials, and planting one tree for every purchase made.

Observer ranked Colorado Botanicals as the #1 CBD company to buy from in 2021, and after learning more about this forward-thinking brand, we understand why.
The company sets itself apart from other CBD companies in two key ways – its proprietary purification process and its intense focus on terpenes. Most CBD brands use high heat to remove chlorophyll, fats, and waxes from their products, but this approach burns off all the terpenes and other essential compounds in CBD. Instead, Colorado Botanicals uses a pharmaceutical chemical separation process that leaves terpenes intact while simultaneously removing all traces of THC.
Terpenes matter because they have a host of healing properties and, when terpenes are present with cannabinoids, receptor activity is higher, meaning more powerful CBD effects. Because Colorado Botanicals’ purification and extraction process naturally retains hemp-derived terpenes, they don’t need to add them from other plants. When terpenes are added (versus preserved), they can dilute the final product and introduce unwanted compounds, resulting in less effective CBD.
However, what really stood out was Colorado Botanicals’ transparency about the amount of terpenes in its CBD. The brand’s broad-spectrum products are tested by third-party labs (ProVerde Laboratories, SC Labs, and FESA Labs), its lab results are posted on its website, and those results show that its products actually contain terpenes. We’ve reviewed a lot of CBD companies, many of whom claim to have terpenes in their products, but it’s extremely rare to encounter a company that shows proof.
Even more impressive, its products are manufactured in an ISO 9001:2015, cGMP-compliant facility, ensuring its product offering meets the highest available standards.
Our favorite Colorado Botanicals product is the brand’s 750 mg Broad Spectrum CBD Oil, which contains 25mg of CBD per serving and comes unflavored or in a delicious peppermint flavor. The brand also sells 1,500mg and 3,000mg bottles as well as gummies, topicals, softgels, and pet products. Additionally, all Colorado Botanicals products are backed by a 60-day risk-free trial. Regardless of which item you pick, you’re getting amazing value, high quality, and a truly excellent product.

A Few Notes to Keep in Mind as You Shop
As you set about your CBD oil shopping in 2021, remember that you never have to settle for less than the best when it comes to supporting and maintaining your own wellness.
Not only are there CBD oil companies out there making amazing and innovative products, you can most definitely find a company that aligns with your values as well.
Whether you are concerned about the environment or social justice, there is something in the CBD industry for you.
And you don’t have to bust the bank to get the wellness you deserve. While CBD prices can vary wildly, you can find a product that meets your needs without costing a fortune.
Why do CBD prices vary so much?
There are plenty of reasons that CBD from one company may cost one price, and something that seems exactly the same from a different company costs a drastically different amount.
One thing to keep in mind is that while some products cost more because a manufacturer is using more expensive products or has invested more in production costs, price does not necessarily indicate quality.
Sometimes CBD companies are more concerned with profits than customers, and they may be inflating the price unreasonably.
Other CBD companies may import the hemp used to make their CBD. The expense related to importing raw materials can lead to a higher-priced finished product.
Sometimes, however, the higher price is justified. When a company invests a significant amount in developing superior products, its products may be a little more expensive.
Companies that have gone through the USDA organic certification process, or companies that use premium ingredients are good examples of companies that have justifiably higher prices.
How to Compare the Cost of Your CBD
There are so many different types of CBD oil out there, and they come in different bottle sizes and concentrations. This makes it difficult to compare one product to another, but it’s nothing a little simple math can’t fix.
You want to look at how much a product costs per milligram of CBD it contains. The easiest example to give would be to compare the cost of a 1000 mg bottle of CBD to a 750 mg bottle of CBD. (These are not intended to reflect an actual product, but to illustrate an example):
1000 mg of CBD $100
CBD costs $0.10/mg
750 mg of CBD $55
CBD costs $0.07/mg
You can use this technique even if you are comparing the price of two completely different products, and it is a way to figure out which formats are most cost-effective.
Keep in mind that the formula may influence the cost of a CBD product as well. CBD oils that are made with CBD isolate are generally less expensive than oils that are made with a broad or full-spectrum formula.
What’s the Difference Between CBD Formulas?
When you are looking for the right CBD for your needs, it's best to keep the difference between the formulas in mind.
CBD Isolate contains only CBD. There are no other cannabinoids present, and it is the least likely formula to contain traces of THC as well.
Full-Spectrum CBD is also commonly referred to as whole plant extract. This means that the process makes use of all the beneficial cannabinoids found in the hemp plant including THC (the intoxicating substance found in cannabis plants).
Full-Spectrum CBD may contain anywhere between zero THC, and 0.3 percent THC.
Hemp is federally legal, and adults 21 and over have a right to choose whether they want to use CBD that contains up to 0.3 percent THC, as long as it was derived from hemp.
Broad Spectrum CBD is the best of both worlds. It contains all the beneficial cannabinoids found in the hemp plant, minus the THC.
In addition to CBD, broad-spectrum CBD may contain CBG, CBN, and CBC, as well as terpenes and other molecules.
Is CBD Legal?
CBD was made federally legal by the Farm Bill (also known as the Agricultural Improvement Act) of 2018. It was this bill that officially took hemp off the list of controlled substances.
States are able to create their own laws surrounding hemp and its derivatives, and some may restrict who can purchase and possess CBD, THC concentrations, and formats.
It’s a good idea to always check the laws in your state before making any new purchases.
How Do I Know if My CBD is Accurately Labeled?
You should always be on the lookout for a certificate of analysis that goes with your product. This provides confirmation that your CBD oil has been lab-tested, that it is free of contaminants and toxins, and that it has the advertised concentration of cannabinoids.
If the company you are shopping with does not display a certificate of analysis on its website, you should still be able to request one by contacting customer service. If you don’t get a response, steer away from the company.
