CBD Terminology

  • Terpenes: aromatic plant compounds with a wide variety of beneficial properties (1).
  • Minor cannabinoids: CBN, CBG, CBC, and other beneficial cannabinoids found in smaller amounts in hemp. They work in synergy with CBD, enhancing its effects.
  • Hemp: non-intoxicating cannabis variety with high CBD and low THC levels (less than 0.3%).
  • Full-spectrum: whole-plant hemp extract containing multiple cannabinoids, terpenes, and flavonoids. This form of CBD is about 4 times more potent than pure CBD (2).
  • Broad-spectrum: whole-plant hemp extract similar to full-spectrum CBD, but with THC removed (may contain trace amounts).
  • CBD isolate: pure CBD with all other hemp compounds removed.

Most of the CBG oils you’ll find contain equal or higher amounts of CBD. If you’re looking for a potent product that’s rich in CBG, NuLeaf Naturals is the best option.

Its full-spectrum oil provides 60 mg of CBG per ml, one of the highest potencies you’ll find. At the same time, it still contains smaller amounts of CBD, THC, minor cannabinoids, and terpenes to make the most of the entourage effect (1).

Established in 2014, NuLeaf Naturals is one of the most trusted American CBD brands.

Our experience: Our product reviewer Antonio took 3 full servings (90 mg CBG) and felt an increased appetite for the rest of the day. He also enjoyed the strong natural hemp seed flavor.

  • Low prices
  • Comprehensive third-party testing
  • Five strength options


  • Smaller CBG concentration (relative to CBD)

We recommend CBDfx’s wellness tincture if you need to avoid THC. It combines a 2:1 ratio of pure CBD and CBG, alongside a blend of terpenes and two other ingredients with a wide range of potential health benefits: curcumin and coenzyme Q10 (3, 4). 

You can choose 30 or 60 ml bottles available in five strengths ranging from 500 to 6000 mg of CBD and 250 to 3000 mg of CBG. Depending on the strength, you’ll end up paying anywhere from $0.02 to 0.05 per mg of cannabinoids, which is well below the average price.

California’s CBDfx is one of the most popular brands on the market. It uses organic hemp grown in Kentucky to make its products and provides comprehensive third-party lab test reports.

My experience: I took one dropper (100 mg) of the 2000 mg CBD/1000 mg CBG tincture. It tasted slightly sweet with a subtle lemon aftertaste. I started feeling relaxed and cheerful in about 40 minutes but the effects were weaker than expected for such a potent tincture.

Extract Labs CBGa + CBDa Tincture (Best CBGa Oil)

  • Full-spectrum formula high in CBGa, CBG, CBDa, and CBD
  • One of the only CBGa oils on the market


  • Only one potency

This unique full-spectrum oil provides the “raw” cannabinoids CBGa and CBDa alongside their “activated” forms CBG and CBD at a 1:1 ratio. You get 500 mg of each cannabinoid, for a total of 2000 mg or 67 mg per ml.

CBGa is the first cannabinoid produced by cannabis plants and gives rise to most other cannabinoids, including CBG. It was highlighted by a January 2022 study that found that CBGa and CBDa blocked the COVID-19 virus from entering human cells.

This CBGa oil costs $0.05 per mg of cannabinoids, a low price for such a unique formula.

Founded in 2016 by army veteran Craig Henderson, Extract Labs is a reputable brand out of Colorado. Its products are sourced from local organic hemp and go through complete in-house and third-party testing.

What is CBG?

Cannabigerol (CBG) is a cannabinoid found in the cannabis plant. It’s non-intoxicating just like CBD, so it can’t get you high. CBG is considered a minor cannabinoid because most cannabis plants contain less than 1% of it.

CBG comes from cannabigerolic acid (CBGa). CBGa is considered the “mother of all cannabinoids” because it’s one of the first cannabinoids made inside the cannabis plant and turns into THCa, CBDa, and other cannabinoid acids (5). Typically, only a small amount of CBGa turns into CBG. 

However, there are some cannabis strains bred for high CBG levels. It’s also possible to get more CBG by harvesting and extracting plants at the optimal time.

What is CBG Oil?

CBG oil is a CBG-rich version of CBD oil. It can contain pure CBG, a specific mix or ratio of CBG and CBD, or CBG-rich full-spectrum hemp extract.

The CBG is dissolved in MCT oil or another carrier oil to improve its absorption and taken under the tongue like a regular CBD tincture.

Most people use CBG oil to boost their mood, relieve anxiety and pain, improve energy, focus, and motivation, and support overall well-being.

Some of the CBG:CBD tinctures we received and tested to help write this review.

CBG Oil Benefits

CBG has many potential health benefits. Although it’s seen less research than CBD, early studies have shown promising results:

  • A 2016 study in rats found that CBG can stimulate appetite (6)
  • A 2013 study in mice reported that CBG improved inflammatory bowel disease (7)
  • According to a 2017 review paper, CBG may have anti-inflammatory, pain-relieving, antibacterial, antidepressant, and anticancer properties (8)
  • Two animal studies of multiple sclerosis (MS) found that CBG and its derivatives improved neuroinflammation (9,10)
  • A 2015 study reported that CBG protected neurons from damage in mice with Huntington’s disease (11)
  • A 2019 petri dish study found that the combination of CBD and CBG reduced neuroinflammation better than either cannabinoid alone (12)
  • A 2010 study found that CBG strongly activates a2 adrenergic receptors, suggesting that it may have pain-relieving, sedative, and antihypertensive effects (13)

Additionally, a 2021 survey of 121 cannabis users who smoked CBG-dominant cannabis strains found that it was most commonly used to treat anxiety (51.2% of users), chronic pain (40.9%), depression (33.1%), and insomnia or poor sleep (30.7%).

Most participants said their symptoms were “very much improved” or “much improved” with CBG-rich cannabis. Additionally, 73.9% said CBG-rich cannabis was better than prescription medicine for pain, 80% for depression, 73% for insomnia, and 78.3% for anxiety (14).

According to leading cannabis researcher Dr. Ethan Russo, CBG also has “a strong anti-anxiety effect.”

While this list of CBG’s potential benefits is impressive, more high-quality human research is needed to fully understand its therapeutic effects.


Both CBG and CBD are non-intoxicating cannabinoids. They have some similar effects, like anti-inflammatory, anti-anxiety, and pain-relieving properties (15). However, CBG also has some distinct effects.

For example, whereas CBD appears to slightly suppress appetite, CBG may have the opposite effect (16). Another interesting finding is that CBG blocks the serotonin (5HT1A) receptor, whereas CBD activates it (13, 17).

CBG Oil Dosage

The right CBG oil dosage depends on your body weight, genetics, the benefits you’re looking for, the formula you’re using, and other factors. In short, there isn’t a one-size-fits-all dosage.

Health experts recommend the “start low and go slow” approach to cannabinoids (18). Start with a 5-10 mg dose of CBG oil and wait two hours to see the effects. If it’s not enough, try a bigger dose next time. Repeat this method until you find the dosage that gives you the desired effects.

Alternatively, you can start with the dosage suggested by your CBG oil.

CBG Oil Safety & Side Effects

Although research is lacking, studies suggest that CBG may have some side effects and interactions. For example, it might interfere with drugs that act on serotonin, such as SSRI antidepressants (10).

The most common side effects reported in a survey of CBG-rich cannabis users were dry mouth, sleepiness, increased appetite, and dry eyes (14). But all of these side effects can’t be attributed to CBG alone, since cannabis contains many other cannabinoids and terpenes.

It’s best to talk with your doctor before taking CBG oil products, especially if you’re on any prescription medications.

How We Chose CBG Oils

I began with a list of about 20 CBG oils from reputable CBD brands. Next, I narrowed down the options to about 10 oils by using the following criteria:

  • Third-party testing (to verify the CBG content and lack of contaminants and check levels of minor cannabinoids and terpenes)
  • Type of CBG (full-spectrum is ideal, but some people may prefer THC-free products)
  • Potency (to avoid products that are too weak)
  • Hemp source (to ensure the plants used to extract the CBD are of high quality)
  • Company reputation (to find a trustworthy brand)
  • Price (to get a good deal)

Then, I tested the remaining 10 oils, taking them all during the day since CBG products are usually recommended for daytime use (in my own experience, CBG has uplifting and possibly energizing effects which make it a great boost during the day).

I made sure to take breaks of at least a day between using CBG to avoid any potential tolerance. Next, I chose the final five CBG oils based on efficacy and the above factors.

Read on for a detailed explanation of why these criteria matter and how to use them.

Look for Third-Party Tested Brands

You should only buy from brands that have their products tested by an independent lab. Potency tests verify that you’re getting as much CBG and other cannabinoids as you should.

Meanwhile, contaminant tests check for pesticides, heavy metals, residual solvents, and other harmful substances.

Look for brands that provide complete third-party potency and contaminant test results. We also recommend checking the test documents yourself to make sure your CBG oil contains the right amount of CBG.

Type of CBG Oil

There are three types of CBG oil:

  • CBG isolate oil, which contains only pure CBG and no other active ingredients.
  • A mixed product that contains a specific ratio of pure CBG and CBD isolate.
  • Full-spectrum CBG oil, which contains a certain amount of CBG alongside CBD and other hemp cannabinoids and terpenes.

If you’re looking for the greatest effects, we recommend full-spectrum CBG oil because it maximizes the entourage effect synergy between cannabinoids and terpenes (1). 

But if you want to avoid THC, go with CBG isolate oil or a mixed CBG/CBD product with zero THC.

Consider Potency

Potency is how many milligrams (mg) of cannabinoids are in a milliliter (ml) of oil. The higher the number, the stronger the product. For CBG oil, this number will either be the amount of pure CBG or the combination of CBG, CBD, and potentially other cannabinoids.

For example, an oil providing 25 mg of CBD and 25 mg of CBG per ml has a combined potency of 50 mg/ml.

We generally recommend high-potency (40+ mg/ml) CBG products because they’re convenient for both new and experienced users. 

Advanced users need stronger products to meet their dosage requirements, while beginners can take fewer drops to feel an effect. So try to look for CBG oil with a potency of 40 mg/ml or higher.

Check the Hemp Source

Since CBG is derived from hemp, the way it’s grown has a big impact on product quality.

Look for companies that use organic hemp and clearly tell you where and how it’s grown. The best hemp sources in the US include Colorado, Kentucky, and Oregon. European countries like Denmark and the Netherlands are also known for top-tier hemp quality.

It’s even better if the company grows and extracts its own hemp or has USDA organic certification.

Company Reputation

When compiling our list of the best products, we look for established brands with positive customer reviews to make sure you’re getting a high-quality product.

We also consider the company’s transparency, which includes revealing its hemp source, third-party test results, and other information that shows trustworthiness.


We look for high-quality CBG oils at a reasonable price. We also help you compare the prices and value of products by listing the price per milligram (mg) of cannabinoids. The average price for CBG oil is about $0.12 per mg.


Is CBG better than CBD?

CBG may be more suitable than CBD for some uses, such as relieving pain or improving your mood. However, it’s far too early to say anything conclusive as more research is needed.

Does CBG boost energy?

Some people who take CBG report feeling more motivated, energetic, and focused, which is why many CBG products are marketed for daytime use. It’s possible that this has something to do with CBG’s effects on adrenergic and serotonin receptors. But there isn’t enough research evidence to substantiate these effects.

How do you take CBG oil?

You can take CBG oil the same way as a regular CBD tincture. Fill the dropper, place the desired number of drops under your tongue, and hold for at least a minute before swallowing.

Does CBG oil help with pain?

Early research suggests that CBG may have pain-relieving effects (8). However, more studies are needed.

Is CBG legal?

Like all hemp-derived cannabinoids, CBG is completely legal.

Where can I buy CBG oil?

You can buy CBG oil in physical stores and online. We recommend the online option because it’s much easier to find high-quality, third-party tested products at affordable prices.

  1. Can’t believe you don’t include Amyris owned brand Terrasana CBG + Squalane oil here? Though it’s not labeled for internal use. This is a brand to watch, as Amyris can bring the rare cannabinoids to market at one of the lowest prices around, with incredible purity and more sustainably than traditional cannabis harvesting methods.

    Not to mention research has shows Squalane boosts skin absorption of CBG by a massive 10-40x compared to other low cost oils that are traditionally used in many of these products….

    Please reach out to Amyris to learn more.
