1. Best 1:1 CBD:CBG Tincture: Medterra CBG + CBD Oil (500 mg CBG; 500 mg CBD)Price: $79.00Pros:
- Contains 500 mg CBD and 500 mg CBG
- Zero THC (These are made with CBD and CBG isolate)
- Medterra is an awesome company (see review for details) with the U.S. Hemp Authority's Seal of Approval
- Made with organic MCT oil and organically-grown hemp (Medterra is pursuing USDA organic certification now)
- Zero THC (not "full spectrum")
- Only one flavor available (citrus)
This Medterra CBG + CBD Oil stands out because it’s made with both CBG isolate and CBD isolate. So it contains 500 milligrams of CBG, plus 500 milligrams of CBD — and zero THC.
We obtained their lab results, to confirm that this tincture does indeed include such a huge amount of CBG. (Because CBG is so difficult to extract, CBG tinctures of this potency are rare.)
Many CBG aficionados like to consume both CBG and CBD together, often in this 1:1 ratio, because they believe the cannabinoids work best together — and they may both play important roles in balancing our endocannabinoid system.
(For more information on how CBG could interact with your endocannabinoid system, scroll down past these product reviews. Look for the section where we nerd out!)
This 1:1 CBG tincture is also one of the newest products from Medterra, a leading CBD company known for high-quality products and ethical business practices.
In April 2020, Medterra donated 300K worth of free CBD tinctures to frontline healthcare workers fighting the pandemic. When I told some nurse friends about it, they were able to upload their badges to Medterra’s frontline worker website, and they received free CBD tinctures in the mail, as promised. So we’re big fans of this company.
Although most of Medterra’s CBD products are made with CBD isolate, they recently began isolating CBG as well as CBD.
(The CBG is much harder to isolate, as they explain on their website, because CBG is scarce in mature hemp plants. Learn more about how CBG is produced at the bottom of this article!)
These hemp extracts are blended with organic MCT coconut oil and citrus flavor. This CBG tincture also comes in a 2000 mg strength (with the same half-and-half ratio of both cannabinoids). You can choose between the two potencies at checkout.
2. Best CBD Tincture with 30 mg CBG: Charlotte’s Web Mint Chocolate CBD Tincture (1800 mg CBD)Price: $164.99Pros:
- Contains a small amount of CBG, plus a large amount of CBD (over 1800 mg per bottle)
- Charlotte's Web is one of the most famous and longest-operating CBD companies on the market today
- This is one of the only Charlotte's Web products for which their potency reports show detectable levels of CBG
- Lab also detected CBN and CBC, two other lesser known cannabinoids
- Full spectrum hemp extract
- Charlotte's Web declined to share third-party Certificates of Analysis (COAs) with us, unlike almost every other reputable CBD company we've contacted
- Instead, they release internally-prepared reports *based* on third-party lab data
- Relatively expensive
- Not created specifically for CBG content (see top 2 products on this list for CBG products)
This Charlotte’s Web Mint Chocolate CBD Tincture stands out because it’s absolutely delicious, and it’s made by one of the most established and respected CBD companies operating today.
Plus, according to internally-produced reports based on third-party lab data, one 30 mL bottle of this tincture contains over 2100 mg CBD, and 30 mg CBG.
You might be wondering: Why “internally-produced reports based on third-party lab data?” Why not give us the data itself?
Charlotte’s Web may be the only CBD company we’ve ever contacted which swears they do conduct third-party lab testing, but declines to share the third-party Certificates of Analysis (COAs) with us. A Charlotte’s Web representative informed us that the COAs contain proprietary information.
(For more information, check out our guide to the best CBD gummies, where Charlotte’s Web products are featured prominently — because we received a free sample of their gummies, tried them out, and concluded that they’re awesome.)
Although we normally never include products without reviewing their third-party lab data, we decided that in this case, reports based on third-party data are sufficient. Because Charlotte’s Web is beloved by CBD customers across the company — and has been for many years.
Charlotte’s Web was founded in Colorado by the Stanley Brothers, who first gained fame when Dr. Sanjay Gupta’s documentary “Weed” aired on CNN.
Long before CBD was in every health food store, these brothers had bred a cannabis strain to produce high CBD and very low THC. They named it after Charlotte Figi, a child with severe epileptic seizures who had found relief after her parents administered their new cannabis treatment.
Now Charlotte’s Web makes its full spectrum hemp products available nationwide.
I’ve reviewed their potency reports for several of their products, and, interestingly, this was one of the only Charlotte’s Web products for which the lab detected CBG. (The lab also detected levels of CBN and CBC, two other lesser-known cannabinoids.)
Also interesting: Like most of their potency reports, it lists “.3%” for THC levels. THC is the only cannabinoid they list as a percentage — and .3% is the exact legal limit for THC in CBD products.
3. Best Broad Spectrum CBD Oil with CBG: Medterra Broad Spectrum CBD Tincture 2000mgPrice: $99.99Pros:
- Medterra was already well-known as a high-quality CBD company approved by the U.S. Hemp Authority; now they're making products with CBG.
- These broad spectrum CBD tinctures include CBD, CBG, CBN, CBC, and CBDV, plus terpenes - but zero THC
- Medterra was one of the first 13 companies to receive the U.S. Hemp Authority seal of approval
- Comes in several flavors and two different strenghts (1000mg and 2000mg)
- It's super easy to check out their lab results (they're right there on the product page!)
- Zero THC (This is not "full spectrum" CBD oil)
- Most of these bottles contain around 10 mg CBG total
- One flavor (citrus) does not appear to have any CBG after all, when we checked the test results (see review for details)
This Medterra Broad Spectrum CBD Oil stands out because Medterra recently started advertising its new CBG isolation capability. These “Broad Spectrum CBD + CBG Tinctures” are part of their CBG-inclusive product launch.
Medterra has been making amazing CBD products for years. But until now, their products were made only with CBD isolate — which, by definition, includes zero CBG.
(CBD isolate is just what it sounds like: It’s CBD that has been “isolated,” in a lab, from all other plant compounds, including terpenes and other cannabinoids.)
Some people love CBD isolate; others prefer broad spectrum or full spectrum CBD, because they believe in the “entourage effect.” (This theory suggests that CBD works most effectively with a “spectrum” of other plant compounds, the way it occurs in nature.)
Although I normally advocate for full-spectrum CBD, we loved Medterra’s CBD isolate products. (Full disclosure: I received a free sample to test out. Check out our guide to the best CBD tinctures for my full review of their 3000mg CBD isolate tincture!)
With this new launch, Medterra is still sticking to its zero-THC guarantee. That’s why these aren’t “full-spectrum” CBD tinctures: the THC has been removed.
They are, however, “broad-spectrum.” They contain other naturally-occurring cannabinoids, including CBG.
This broad spectrum CBD oil comes in a variety of flavors, and two potency levels: 1000mg and 2000mg. (The milligrams listed refer to the CBD content.) Each bottle contains 30 servings, and each serving is a dropper full of oil.
In the 2000mg version, each serving will contain 66 mg of cannabinoids, according to the product description, including “CBD, CBG, CBN, CBC, and CBDV.”
Medterra makes it super easy to check out their third-party lab results, which are conducted by Green Scientific Labs. Right on the product page, you can check out lab results for each flavor and potency.
Both the Strawberry Mint 2000mg version and the Unflavored 2000mg version contain about 10 milligrams CBG per bottle. Interestingly, the Citrus Flavor 2000mg version did not appear to include any detectable CBG. But it did include CBN and CBC. So if you’re specifically looking for CBG, you may want to check out the lab results for the flavor you have in mind. Luckily, Medterra makes that super easy!
4. Best if You’re Not on a Budget: Green Garden Gold One2One CBD & CBG Tincture (500 mg CBD; 500 mg CBD)Price: $111.99Pros:
- Contains 500 mg CBD and 500 mg CBG
- Third-party lab did not detect any THC (or any other cannabinoids), but did confirm 1:1 CBG:CBD ratio
- Green Garden Gold sources hemp from organic hemp farmers in Colorado
- Green Garden Gold does not publish test results for heavy metals, microbials, residual solvents, or pesticides
- Does not contain THC, which some experts believe may be crucial to unlocking the entourage effect (in which cannabinoids act synergistically in your body)
- Relatively expensive, compared to some 500 mg CBD tinctures (without CBG)
This Green Garden Gold One2One CBD & CBG Tincture stands out because it contains exactly equal parts CBG and CBD — but no THC.
These two anti-inflammatory cannabinoids coexist in this tincture in equal amounts, as the name “One2One” suggests.
We have not seen this 1:1 CBD:CBG ratio in any other products. If you want to discover how these synergistic cannabinoids can help support your body and mind, this is the CBG tincture for you.
These third-party lab results by Altitude Consulting found that one bottle of this tincture contains 513 mg CBD, and 513 mg CBG. The lab did not detect any THC, or any other cannabinoids.
Plus, Green Garden Gold sources their hemp from organic hemp farms in Colorado.
But such an innovative, clean product doesn’t come cheap. In fact, according to Forbes, CBG is among the most expensive cannabinoids to produce.
That explains why this high-CBG tincture is more expensive than many CBD tinctures.
5. Best CBG Gummies: Green Garden Gold CBG Gummies (Zero CBD, Zero THC)Price: $39.99Pros:
- Made with CBG isolate (no THC; no CBD)
- Third party lab results confirm that each gummy contains over 16 mg CBG
- Perfect for anyone who wants to see how CBG may interact with their endocannabinoid system differently than CBD
- Main ingredient is corn syrup
- Not vegan (contain gelatin)
- New product, so no customer reviews available yet
These Green Garden Gold CBG Gummies stand out because they’re actually made with CBG isolate. That means they don’t contain any other cannabinoids — no THC, and no CBD.
These are the only CBG products we’ve seen made with CBG isolate. (And Green Garden Gold refers to them as the “world’s first.”)
These third-party lab results confirm that no cannabinoids (aside from CBG) were detected when these gummies were tested. The lab found that each gummy contained over 16 mg CBG.
If you’re interested in trying CBG — and you want to discover how CBG may interact with your endocannabinoid system differently than CBD — these gummies could be perfect for you.
We have reached out to the company for more information on their CBG extraction process. We’ll update this review when we have more information!
6. Best With .02% CBG: Mana Botanics CBD Oil (300 mg)Price: $60.00Pros:
- Third-party lab results show .02% CBG, as well as 1.1% CBD (and .05% THC)
- Ingredients grown on sustainable farm in Hawaii (where they're based)
- All other ingredients (locally-grown macadamia nut oil, turmeric, vanilla) are certified organic
- This is a smaller company, which doesn't have many customer reviews (yet)
- Not ideal for anyone who doesn't like turmeric (or vanilla)
- Not certified organic, although they are working towards certification now (have moved away from livestock operations on their farm)
Mana grows ingredients at their own farm on the Big Island of Hawaii, where the company is based. Hawaii is known for its volcanic soil, which is rich in minerals and nutrients.
Mana Botanics also grows other crops, as part of their commitment to regenerative agriculture and community wellness.
Their farm also serves as a wellness retreat. You could actually go see the ingredients in this tincture being grown (organically). That’s a whole new level of transparency for a CBD product.
All the other ingredients, including macadamia nut oil, turmeric, and vanilla, are certified organic.
Other strengths are also available, as well as a coconut oil version that’s nut-free.
7. Best Mood-Boosting CBD Tincture With 18 mg CBG Per Bottle: Eco Sciences ECODrops “Boost” Tincture (1500 mg CBD)Price: $134.99Pros:
- Contains nearly equal amounts of THC and CBG (about 17 mg of each cananbinoid per bottle)
- Also contains over 1500 mg CBD
- Eco Sciences posts batch-specific third-party lab results on their website (and makes it easy to view several batches' results for any product you're interested in)
- The test results do not appear to include results for heavy metals, pesticides, residual solvents, or microbials (just potency results only)
- Relatively expensive
- Not specifically formulated to contain CBG (it's just there, because it's truly "full spectrum" CBD oil)
The Eco Sciences ECODrops “Boost” Tincture stands out because it includes 1500 mg CBD, as well as 18 mg CBG (and 17 mg THC).
We haven’t seen any other full spectrum CBD oil with its THC and CBG content so close to equal.
This CBD oil also includes a terpene blend formulated to help improve your mood.
And unlike many CBD companies that post batch-specific lab results, you don’t have to wait until you have a package in your hand (ie. after you’ve already bought it) to look at the lab results for the product you’re interested in.
You can review several batches of this tincture. And if you look at the potency results for the most recent batch, you’ll see that it contains over 1500 mg CBD (as advertised), plus 17 mg THC and 18 mg CBG. (And, in case you’re interested, it also contains 5 mg CBV, 96 mg of CBN, and 71 mg of CBC.)
If you’re looking for a full spectrum CBD oil with enough of all the lesser-known cannabinoids to maximize their synergy in your body, this is the tincture for you. It even includes 5 mg of CBL, a truly under-the-radar cannabinoid.
What's the difference between CBG vs CBD?
Cannabigerol (or CBG) is often referred to as the "mother cannabinoid," because it is the precursor to CBD and THC. As the plant matures, its CBG converts to THC and CBD.
So in mature cannabis plants, CBG is usually found only at very low levels. This is part of why CBG is so hard to produce -- and why most CBD companies don't offer it. (For more on why it's so difficult to obtain, scroll down.)
Like CBD, CBG attaches to receptors in our endocannabinoid system. Our endocannabinoid system is a network of cells and receptors in our body, which helps regulate several bodily functions, including pain, mood, appetite, and memory.
The endocannabinoid system is vital to your health -- whether you consume cannabis or not. Our body produces its own molecules that are nearly indistinguishable from the cannabinoids found in cannabis. These endogenous cannabinoids are called "endocannabinoids." (For further reading, I highly recommend The Botany of Desire, by best-selling author Michael Pollan.)
Today, scientists are discovering that problems in our endocannabinoid system may be responsible for numerous health problems. For example, people suffering from post-traumatic stress disorder (PTSD) have been found to have impaired endocannabinoid systems.
Researchers are discovering the myriad benefits of balancing your endocannabinoid system. Of course, more research is needed.
CBG oil vs CBD oil
Like CBD, CBG binds to cannabinoid receptors in your body, which are found in your brain, nervous system, and other vital organs.
But when it comes to certain receptors and channels in our bodies, CBG can be more (or less) potent than other cannabinoids. Read on for more of the existing research from peer-reviewed studies.
What are the main CBG benefits?
There have been few CBG studies (if any) conducted on humans, and the FDA regulates what we can and cannot say about CBG benefits.
But we can tell you about the existing peer-reviewed studies on animals and cells.
For example, two studies indicate that CBG may help protect our brains from the effects of aging.
In 1992, Italian scientists found that CBG has neuroprotective effects. By studying the effect of CBG on cells in vitro, they discovered that CBG can protect against both neuroinflammation and oxidative stress -- two main reasons our brains deteriorate as we get older.
In 2015, researchers in Spain treated mice with CBG. (The mice had forms of Huntington's Disease, a neurogenerative disorder that afflicts humans.) They found that "CBG was extremely active as a neuroprotectant," and reduced certain markers of the disease in mice brains.
This opened new avenues, the researchers concluded, for using CBG to treat neurodegenerative disorders.
CBG may also hold promise for treating chronic pain.
In 2010, Italian scientists working with GW Pharmaceuticals measured the effects of several cannabinoids on cells that make up important pathways in bodies. (These channels produce the sensations we experience as pain and discomfort.)
They found that CBG (when combined with other cannabinoids with which it normally occurs in plants) was most potent on certain ion channels, including the one that translates to the sensation of cold and cold pain. It also inhibited two other major channels associated with the experience of pain.
"In particular, CBG-BDS, due to its ability to inhibit both MAGL and NAAA, and antagonize TRPM8, should be tested in the future in animal models of chronic pain," the scientists working with GW Pharma concluded.
In English, please?
CBG holds a lot of promise for chronic pain sufferers -- and at least one major pharmaceutical corporation is already looking into it.
Interestingly, CBG by itself had a limited impact on these bodily channels.
"A ‘CBG-free’ CBG-BDS was found to be inactive per se," the researchers wrote, "but when added to pure CBG, the activity of CBG-BDS was restored and this compound was significantly more potent and efficacious at antagonizing TRPM8 than pure CBG, thus pointing to a synergistic effect between this cannabinoid and some of the components of its corresponding Cannabis extract."
This is more evidence for the"entourage effect." But the entourage effect is a theory normally associated with CBD. (Experts suggest that CBD is more effective when consumed with other cannabinoids, including small amounts of THC.) This study points to this same synergy -- but applied to CBG.
CBG may also hold promise for sufferers of Irritable Bowel Syndrome (IBS) and colon cancer, according to studies conducted on mice.
In 2013, researchers in Italy experimented with CBG on mice with symptoms of Irritable Bowel Disease (IBD). They found that “CBG could be considered for clinical experimentation in IBD patients.”
In 2014, these scientists experimented with CBG on models of colon cancer in mice. They found that CBG inhibited both tumor growth and colon cancer progression in mice.
So what is CBG good for?
Due to FDA regulations, we can't legally tell you how CBG can help you.
But if you want to make your own decisions based on these studies explained above, you could experiment with CBG. (And if you're interested in anecdotal accounts of its mood-boosting effects, keep reading!)
Should I stock up on CBG products right now?
That's up to you! Try to pay attention to what CBG dosage helps you feel better. And keep in mind: Just because CBG alleviated IBS and colon cancer in mice, that doesn't necessarily mean it will relieve your IBS (or stop your tumor growth).
And just because CBG had a neuroprotective effect on mouse brains, doesn't necessarily mean it will protect your brain against neurological diseases.
But animal and cell studies are often the precursors to clinical trials on humans. And scientists are advocating for clinical trials for CBG.
In fact, the U.S. National Institutes of Health (NIH) is already researching the use of minor cannabinoids, including CBG, as a treatment for pain.
But federal agencies and Big Pharma are unlikely to share any of their findings with us anytime soon. So individuals and smaller companies are taking matters into their own hands.
We spoke with Mansal Denton, the nootropic advisor to a new supplement company called Sovereignty, which aims to make CBG products available to the public soon.
The company conducted a survey of hundreds of people who consumed their sample products. Seventy percent of respondents experienced mood-enhancement or euphoria after taking their products, Denton said.
"Through our surveys, experiences and lab partners, we've noticed higher amounts of CBG seem to cause euphoria," he explained. He'd noticed this effect after taking CBG himself, too.
Denton theorized that this may have something to do with anandamide, one of the endogenous cannabinoids produced by our bodies. Anandamide is so important to our mood regulation that it is often called the "bliss molecule."
And in that GW Pharma study (summarized above), researchers found that CBG may impact anandamide uptake.
For evidence of CBG's mood-boosting properties, more research is needed. But that doesn't mean you can't try it yourself.
Do any of these products contain pure CBG oil?
Yes! The CBG gummies reviewed above contain CBG isolate. That means it's CBG that has been isolated from other plant compounds (like CBD or THC).
Why is CBG oil so expensive?
There are very few companies currently selling CBG products. The CBG tincture and CBG gummies reviewed above are among the few commercially-available products available today.
Some companies which previously offered CBG products have stopped selling them.
"Finding a reliable, safe source at the time was very difficult," says Michael Harinen, Chief PR and Communications Officer at Bluebird Botanicals, which also stopped carrying its CBG tincture due to a lack of studies about its safety.
It also requires an enormous amount of plant material, because CBG occurs in such minute amounts in hemp plants.
"Plants must either be harvested early," Harinen explains, "or bred specifically to reduce the enzyme that will break CBG down. The former method means low yields and there aren't many cultivars of the latter."
Will there be more CBG oil for sale soon?
Some plant scientists are working on breeding plants with higher levels of CBG.
Others theorize that therapeutic cannabinoids will one day be cultivated in labs -- no plants needed. (Researchers have already produced cannabinoids using genetically altered yeast cells.)
Until then, CBG is likely to remain expensive -- and relatively rare.
Why did you include CBD oil products that aren't packed full of CBG?
As we discovered from the peer-reviewed research summarized above, CBG may work synergistically with other cannabinoids found in hemp plants.
It's a new twist on the theory of the "entourage effect," which is normally used to advocate for taking full spectrum CBD (or broad spectrum CBD) instead of CBD isolate.
It turns out the same theory may apply to CBG. And who's to say what ratio of CBG to CBD (and/or THC) is right for you?
