CBD Topicals Market Report – Less than 1 in 4 CBD topicals contain the amount of CBD labeled

The CBD industry has come a long way in the past few years. More and more products are tested by a third-party lab, made from higher-quality ingredients, and offered at ever-falling prices.

But one problem seems to persist: incorrect amounts of CBD. That’s what we discovered in our independent studies by sending CBD products from different brands for third-party testing at Las Vegas’ Canalysis Laboratories.

So far, we’ve done reports for CBD oils, drinks, and edibles. In this report, we extend our findings to topical CBD products, an increasingly popular category that includes balms, creams, beauty products, and more.

We tested 40 products from various popular and lesser-known CBD brands. Here’s what our investigation revealed.

Note: We’ve done similar reports for CBD prices to help you save money and figure out if you’re getting a good deal on CBD.

Summary

Most of the topical products we tested didn’t contain the correct amount of CBD, with only nine receiving our A rating. The rest were off by anywhere from 12% to 99% from the label.

These findings are similar to what we found in our previous report on edibles. This isn’t surprising as topical products are more difficult to formulate than CBD oil and typically use smaller amounts of CBD, making it harder to maintain a consistent amount.

Here’s a look at the key findings:

• Only 9 of 40 tested topical products had CBD levels within 10% of the label, which is required for an A rating
• 11 products received the worst (F) rating for being off 30% or more from the label
• The majority of the products (31 or 77.5%) contained more CBD than advertised
• Lesser-known brands were more likely to perform poorly than major companies; however, there were a couple of small or new brands that received an A

Take a look at our buying guides

With such a wide variety of available CBD products, it’s not always easy to make a choice and find the right product for your needs.

Therefore, we examined dozens of brands, comparing their prices, third-party testing results, potency, hemp quality, and other factors.

We researched CBD products for different consumption methods and for different health conditions to help you find the most suitable ones.

• Best CBD oil – We chose these CBD oils from a list of over 3000 CBD products and 150 brands, comparing them by third-party lab test results, hemp quality, reputation, price, and other criteria.

• Best CBD gummies – Because there are so many CBD gummies out there, it can be difficult to figure out which product is suitable for your needs. We’ve compiled a list of some of the finest CBD gummies on the market. For those seeking a sleeping aid, we have also compiled a comprehensive list of the best CBD gummies for sleep. We did the same for the best CBD gummies for pain.

• Best CBD capsules – One popular delivery system is CBD capsules and softgels. These are used like any other capsule or softgel, which makes it a simple, convenient way to take CBD

• Best CBD for dogs & cats – There are a wide range of CBD products for pets out there, from tinctures and treats to balms, salves, and creams. Because interest in CBD has increased, more companies are creating pet-specific CBD items, which means we’re spoiled for choice. If you’re shopping for CBD pet products, you might be overwhelmed by all the choices out there

• Best CBD for pain – Many people use CBD products for pain relief. This isn’t surprising as research has shown that CBD can help with various types of pain. As part of our research, we compared dozens of CBD products in order to determine the most effective ones for treating pain. We also created a list of the Best CBD for Arthritis.

• Best CBD for anxiety – Our team of medical doctors, nutritionists, and other health experts chose these products based on their quality, transparency, price, and other criteria. For example, all of the products we recommend are tested by a third party lab to verify their potency and safety.

• Best CBD for sleep – However, the wide variety of available CBD products can be overwhelming. That’s why we researched and compared dozens of brands to find the best CBD ones for sleep.

• Best full spectrum CBD oil – Full-spectrum CBD is a whole-plant hemp extract. It contains the complete range of cannabinoids, terpenes, flavonoids, and potentially other compounds naturally present in hemp. We used our database to compare hundreds of CBD oils based on objective criteria. In this post, we’ll review the most effective full-spectrum CBD tinctures that we found.

Accuracy Rating

We rated the accuracy of topical CBD products by comparing how much CBD they should have to the amount shown on our third-party lab test reports.

While some variation is expected from a natural product like hemp-derived CBD, it should still be within reasonable levels. Industry experts recommend that cannabis products should contain cannabinoid levels that are within 10% of the advertised amount.

As such, a CBD product should contain anywhere from 90% to 110% of the amount stated on the label to be considered accurate.

Using this benchmark, we assigned topical CBD products one of four ratings to represent their accuracy:

1. A (Excellent): independent lab tests showed CBD levels that were within 10% of what was stated on the label.
2. B (Decent): independent lab tests showed CBD levels that were within 20% of the label.
3. C (Poor): independent lab tests showed CBD levels that were within 30% of the label.
4. F (Fail): independent lab tests showed CBD levels that differed from the label by more than 30%.

CBD Third-Party Testing Explained

Third-party tests are done by an independent lab to confirm the safety and potency of a CBD product.

These tests are important when shopping for CBD because there’s no regulation preventing companies from selling low-quality products that have incorrect CBD levels or carry contaminants.

The most important third-party test is called a potency or cannabinoid profile. It shows the amounts of CBD and other cannabinoids in a CBD product to verify the company’s claims.

This is the test that we ordered for our independent reports. Verifying the potency of a CBD product is important for several reasons:

• You want to know you’re getting exactly what you paid for
• A product with less CBD than claimed will be less effective
• A product with more CBD than claimed will make it harder to figure out your dosage

Certificate of Analysis (CoA)

We purchased 40 topical CBD products and sent them to the cannabis lab Canalysis for third-party testing. The results of the tests were recorded in documents called certificates of analysis (CoAs).

Next, we compared the amount of CBD shown on the CoAs to the advertised CBD content of the product.

To give you an example, if a company sold a CBD cream that should contain 300 mg of CBD but the tests only showed 200 mg, that means it contained 33% less CBD than claimed.

This poor result would receive our F rating since you’d be getting significantly less CBD than you paid for.

How to Read CoAs

Most CBD companies publish third-party CoAs directly on their website.

This way, it’s easy for you to confirm that a CBD product is safe, reliable, and effective before buying it.

Reading a CoA may seem difficult because of the scientific jargon and abbreviations, but it’s not that complicated. The main thing to look for is the section called “cannabinoids,” “cannabinoid profile,” “potency,” or something similar.

Here, you’ll see columns and graphs with names of cannabinoids such as CBD, THC, and others, and their amounts in percentages or milligrams (mg) per milliliter (ml), gram, serving, unit, or the whole container.

If you want more info on reading CoAs, check out our detailed guide.

Summary Table

Below is the summary of the third-party test results for the 40 topical CBD products we sent to Canalysis. Most of these products were CBD creams and balms but some also came in the form of serums, toners, and other topicals.

Note that products with a minus sign under the variance column contained less CBD than stated on the label, while others had more.

Discover our list of the best CBD cream and other topicals, based on criteria such as price, company reputation, and customer service.

Disclaimer: Our report is based solely on the test findings. Test results may vary due to the natural variation of CBD levels in hemp, degradation of CBD and other cannabinoids over time, and other factors. Our findings should not be seen as conclusive, complete, error-free, or at all times methodologically or scientifically accurate.

*Total amount includes CBD and CBDA, another beneficial cannabinoid.

Conclusion

Most of the topical products we examined contained inaccurate CBD levels.

Out of 40 tested products, only 9 (22.5%) received our A rating for containing the correct amounts of CBD, whereas 14 received a B, six got a C, and 11 products received the worst F rating.

Compared to our previous reports, these findings suggest that topical CBD products are not as accurate CBD oils.

We expected this because topicals are harder to formulate, requiring the blending of CBD with many other ingredients.

On top of that, they often contain small amounts of CBD, which means that differences of even a few milligrams can have a big effect.

To illustrate this, consider a CBD cream with 500 mg of CBD and another one with 50 mg. A difference of 5 mg would change the accuracy of the first product by only 1% compared to 10% for the second one.

It’s harder to consistently provide the right amounts of CBD in a topical product, which may explain why bigger, reputable brands performed on our tests better than lesser-known companies.

We also found that some companies need to do a better job of stating what’s in their topical products.

For example, one brand didn’t clearly explain that its cream contains 500 mg of CBD and CBDA, another beneficial cannabinoid, while another only listed the amount of hemp extract.

In conclusion, if you want to buy a high-quality CBD topical, be sure to choose a leading brand and check the product’s third-party lab test results beforehand.

Detailed Test Results

CBDfx CBD Muscle & Joint Cream

CBDfx is one of the country’s leading CBD brands, so we had high hopes for their muscle & joint CBD cream.

Third-party tests showed a CBD content of 546.3 mg, which is 9.3% higher than the amount stated on the label: 500 mg.

That’s a great result that falls well within the 10% range needed for our A (excellent) rating.

Erth CBD Face Serum

Earth Hemp is not the biggest name in the CBD industry but that doesn’t necessarily mean its products are of low quality.

We tested the company’s CBD face serum, which should contain 250 mg of CBD. Our third-party tests revealed an actual content of 272.2 mg, which is only 8.9% higher.

That’s a great result that’s deserving of an A rating.

Lazarus Naturals CBD Lotion

Oregon’s Lazarus Naturals is one of the most respected and trusted names in the CBD industry, so we were curious to see how its products would do.

We sent the company’s CBD lotion for testing. It’s supposed to provide 300 mg of CBD and the test documents showed 317.1 mg, which is only 5.7% higher — one of the best results we saw from any brand.

The tests also showed significant amounts of other beneficial cannabinoids, confirming that this lotion is made with full-spectrum hemp extract.

Combined with the excellent results shown by the company’s CBD oil in our previous report, this proves yet again that Lazarus Naturals is one of the best companies on the market.

Koi Naturals CBD Healing Balm

Koi CBD is another established CBD brand. It’s best known for CBD vape products, so it was interesting to see if Koi’s other products match up in terms of quality.

We sent Koi’s CBD balm for third-party testing, revealing that it contained 143 mg of CBD, which is slightly lower (4.7%) than the advertised amount of 150 mg.

The tests also showed significant levels of other beneficial cannabinoids, confirming that this balm is made with full-spectrum hemp extract.

This is one of the best results that we saw, solidifying Koi’s reputation as a reliable CBD company.

Green Gorilla CBD Balm

Green Gorilla stands out for offering USDA organic-certified CBD products. But does that mean its products provide the correct amount of CBD?

Our tests showed that the company’s CBD balm contains 319.5 mg of CBD, which is only 6.5% higher than the labeled amount of 300 mg. That’s a great result.

The tests also showed notable amounts of other beneficial cannabinoids, confirming that this balm is made with full-spectrum hemp extract.

Medical Mary CBD Relief Cream

Medical Mary is a lesser-known brand with a full range of CBD products.

We sent the company’s relief cream for third-party testing. The results showed a CBD level of 510 mg, which is only 2% higher than the 500 mg stated on the label.

This is the best result out of all the brands we tested, proving yet again that a company doesn’t need to be well-known to offer excellent products.

Social CBD Muscle Rub

Portland’s Social CBD is a relative newcomer to the scene. We tested its CBD muscle rub, which is advertised to contain 50 mg of CBD. Our tests showed an actual content of 54.9 mg, which is 9.8% higher.

That’s just small enough to fall within the 10% variance range we expect from high-quality CBD products, so Social CBD gets a well-deserved A rating.

Steve’s Goods CBD Relief Balm

Steve’s Goods is known for offering hard-to-find products such as CBG oil. But what about its standard CBD product lineup?

Our tests of the company’s CBD relief balm showed 528 mg of CBD and CBDA, which is 5.6% higher than the labeled amount of 500 mg. That’s an excellent result that suggests Steve’s Goods is a reputable brand.

The tests also showed some of the highest levels of non-CBD cannabinoids we’ve ever come across, confirming that this is a high-quality, full-spectrum hemp product.

Our only criticism is that the company should make it clearer that this cream contains 500 mg of CBD and CBDA rather than just CBD.

Receptra Naturals Yoga Balm

Receptra Naturals may not be as well known as some other companies from the state of Colorado but has all the signs of a top-tier brand.

We tested its yoga hemp balm, which should contain 400 mg of CBD. It actually had 416.8 mg, which is only 4.2% higher — one of the best results we saw.

The tests also showed large amounts of other beneficial cannabinoids, although there was no THC detected, which should be present in a full-spectrum hemp product.

CBDistillery CBD Balm

CBDistillery is undoubtedly one of the giants of the CBD industry. But does that mean its products are of high quality?

We tested the company’s CBD balm, which should contain 500 mg of CBD. Our third-party tests showed 561.4 mg of CBD, which is 12.3% higher.

This is a decent result and it’s always better to get more CBD than less. Still, it’s slightly shy of the 10% variance we expect from a top-tier CBD product.

The tests also showed significant amounts of other beneficial cannabinoids, confirming that this balm is made with full-spectrum hemp extract.

cbdMD CBD Recover Cream

CbdMD is a well-known brand of THC-free CBD products. We tested its CBD recover cream, which should provide 300 mg of CBD per container.

Our third-party documents showed a real amount of 344.4 mg, which is almost 15% higher. That’s not a terrible result, especially considering that you’re getting more CBD than you paid for.

Still, it’s outside the 10% CBD variation expected from a high-quality product.

Nanocraft CBD Muscle & Joint Stick

California’s Nanocraft CBD is best known for offering products made with nanotechnology to improve CBD’s absorption.

We tested its muscle & joint stick, which should provide 250 mg of CBD. Our third-party tests showed 287.5 mg of CBD, which is almost 15% higher.

Again, this result is not that bad. However, it’s not accurate enough for our A rating so it gets a solid B.

The documents also showed notable levels of other cannabinoids. While this is good, the tests also detected THC, which shouldn’t be present in a broad-spectrum CBD product.

JUSTCBD Relief Cream

JustCBD is best known for its wide variety of edible CBD products. But what about its topicals?

We sent the company’s relief cream for third-party testing, revealing that it contained 287 mg of CBD, which is 14.8 higher than the advertised amount of 250 mg.

While not a bad result, it still falls short of our excellent rating and scores a B.

Irwin Naturals CBD Balm

One of the largest dietary supplement brands in the U.S., Irwin Naturals recently expanded into the CBD market.

We tested its CBD balm, finding that it contained 288.6 mg of CBD instead of the 250 mg it says on the label, which is 15.5% higher.

That’s an okay result but it’s only enough to score a B, especially considering the company’s experience in making supplements.

Kanibi CBD Sports Heat Cream

Kanibi is a fairly new CBD company, having only been formed in 2019.

We examined its sports heat cream, which should have 250 mg of CBD but showed 211.2 mg on the test. That’s 15.5% less than the label.

While not a terrible result, this amount of CBD is lower than what you’re paying for, so it gets a B.

The tests also showed notable levels of other beneficial cannabinoids, confirming that this balm is made with full-spectrum hemp extract.

Karibo CBD Hand & Body Lotion

Karibo specializes in CBD skincare & beauty products so we had high expectations.

We tested the company’s CBD Hand & Body Lotion, which is claimed to have 100 mg of CBD. The tests showed an actual CBD content of 119.6 mg, which is almost 20% higher.

This result isn’t that bad, especially since you’re getting more CBD than you paid for. Still, we expect more from a brand that only sells CBD topicals.

Medterra CBD Cooling Cream

Medterra is another big name in the CBD industry. We took a look at its CBD cooling cream, which should have 250 mg of CBD.

Our third-party tests showed 293.9 mg, which is 17.5% higher. While it‘s certainly nice to get more CBD than less, this result gets a B because it’s not accurate enough.

Proleve CBD Salve

Proleve is a fairly small CBD company out of Tampa, Florida. We tested its CBD salve, which is advertised to contain 100 mg of CBD.

Our third-party testing revealed a CBD content of 84.7 mg, which is 15% lower. This result gets our B rating since it falls short of the 10% variation needed to score an A.

Nightingale Remedies CBD Relief Cream

Formed in 2015, Nightingale Remedies is a CBD brand based in Portland, Oregon.

We tested its CBD relief cream, which is supposed to have 250 mg of CBD but actually contained 296.2 mg. That’s 18.5% higher, which is not a bad result, especially as you’re getting more CBD rather than less.

Still, it’s not quite good enough for our A rating.

Additionally, the tests showed the presence of THC. This seems to dispute the company’s claim that its cream is free of THC.

Original Hemp Soothing Body Cream

Original Hemp offers all the major types of CBD products, including a cream.

We tested it through our third-party lab, showing 589.6 mg of CBD instead of the advertised amount of 500 mg.

That’s almost 18% higher, which is too big of a difference to receive our A rating.

The tests also showed significant levels of other beneficial cannabinoids, confirming that this cream is made with full-spectrum hemp extract.

PlusCBD Oil Hemp Skin Serum

One of the first brands to offer CBD oil in the U.S., PlusCBD is one of the most respected, scientifically-driven companies in the industry.

Its CBD oil performed well on our previous report, so we were curious to see if the company’s skin serum would match this.

It’s supposed to have 50 mg of CBD but our tests showed 58.4 mg, which is 16.8% higher.

That falls short of the 10% difference expected from an accurate product. Still, it’s an okay result because this product has a low CBD strength.

The tests also detected many other cannabinoids, verifying that this serum is made with full-spectrum hemp extract.

Seabedee Relief Cream

It’s always interesting to see how smaller CBD brands measure up to the big names of the industry. One such brand is Seabedee, whose relief cream should contain 500 mg of CBD.

The tests showed that it carries 578.9 mg, which is almost 16% higher. That’s an okay result but it’s not good enough to receive our A rating.

The tests also showed notable levels of other cannabinoids, confirming that this cream is made with full-spectrum hemp extract.

Elixinol CBD Hemp Balm

One of the first and most established CBD companies out there, Elixinol is a truly global CBD brand.

As such, we expected good results from its CBD hemp balm. The label says it should provide 50 mg of CBD but our third-party tests showed 59.2 mg, which is 18.5% higher.

That’s a decent result, especially given the low CBD strength of the cream.

Although the tests also showed notable amounts of other cannabinoids, there was no THC or THCa, which should be present in a proper full-spectrum hemp extract.

CBDMedic Arthritis Aches & Pain Relief Ointment

CBDMEDIC specializes in CBD-infused topicals for specific health concerns. It was also recently acquired by CBD giant Charlotte’s Web, so we expected good results.

We tested its arthritis aches & pain relief ointment, which should have 200 mg of CBD but actually contained 251.1 mg.

This result is 25.5% off from the advertised CBD level, which is quite significant. As such, it gets our C rating.

Avid Hemp CBD Chill Gel

Florida’s Avid Hemp has a wide product lineup, including six topicals.

We looked at the company’s CBD chill gel, which should provide 100 mg of CBD. Our third-party tests revealed that it contains 122.6 mg of CBD, a difference of 22.6%.

This falls under our C rating since it’s more than 20% off from the advertised level of CBD.

The tests also detected other beneficial cannabinoids, confirming that this balm is made with full-spectrum hemp extract.

MAXCBD Eye Cream

MAXCBD is a lesser-known CBD brand based in Florida. We tested its eye cream, which should carry a small amount of CBD: 25 mg.

Our tests showed an actual content of 30.1 mg, which is 20.4% higher.

Although that falls within our C rating, it’s not that bad of a result given the low CBD strength of this product.

The tests also showed other beneficial cannabinoids, confirming that this balm is made with full-spectrum hemp extract.

Sunmed Daytime Lotion

Sunmed is a brand better known for its franchise of “Your CBD” stores found across the country.

We looked at its daytime topical lotion, which should carry 30 mg of CBD but showed 37.7 mg on our third-party tests.

Percentage-wise, that’s not a good result, since it is 25.7% higher than the label. Still, we can’t be too critical since this lotion has a low CBD strength.

The tests also showed significant levels of other cannabinoids, confirming that this lotion is made with full-spectrum hemp extract.

Plant People Relief Body Cream

The relief body cream from Plant People is one of the most potent topical products we looked at, so we were curious to see if its CBD content matched the label.

It’s supposed to provide 750 mg of CBD but our third-party tests showed 928.3 mg of CBD, which is 23.8% higher.

That’s not the greatest result, especially given the high CBD strength of this product, so it gets a C.

The tests also detected other cannabinoids, verifying that this cream is made with full-spectrum hemp extract.

Veritas Farms Eye Cream

Veritas Farms is yet another major brand coming from the heart of the U.S. hemp industry — Colorado.

We examined its eye cream, which should have 100 mg of CBD. Our tests showed an actual content of 125.3 mg, which is 25% higher.

Again, while we do like to get more CBD than less, 25% is a fairly large difference so this product gets our C rating.

The tests also detected other cannabinoids, verifying that this cream is made with full-spectrum hemp extract.

7 Point Naturals Hemp Oil Moisturizer

Seven Point Naturals is a brand that we haven’t come across before, so we didn’t have high expectations from its hemp oil moisturizer.

It’s supposed to contain 500 mg of CBD but our tests showed only 1.2 mg. That’s 99.8% less than what it should be, which is easily the worst result in our report.

That’s well-deserving of our F rating.

Charlotte’s Web CBD Balm

Charlotte’s Web is one of the first and biggest CBD brands out there, so we had high expectations from its CBD balm.

This topical should provide 150 mg of CBD but our tests showed 197.7 mg, which is 31.8% higher.

Unfortunately, that’s a poor result that falls squarely within our F rating, especially given the company’s stellar reputation.

The tests also showed significant amounts of other cannabinoids, confirming that this balm is made with full-spectrum hemp extract.

Envy CBD Soothing Balm

Envy CBD offers a wide variety of topical and skincare CBD products. We tested its CBD soothing cream, which should have 200 mg of CBD.

Our third-party tests showed 290 mg, which is almost 45% higher.

While it’s nice to get more CBD than you paid for, this much of a difference is simply too big and gets our F rating.

The tests also showed significant amounts of other beneficial cannabinoids, verifying that this balm is made with full-spectrum hemp extract.

CBD Living CBD Salve

CBD Living is better known for its CBD-infused water but also offers other products, including topicals.

We tested its CBD salve, which is supposed to contain 100 mg of CBD but our tests showed 139.3 mg.

That’s almost 40% higher than the label, which is a fairly poor result, even if you’re getting more CBD than you paid for.

CBD American Shaman CBD Face Cream

CBD American Shaman has one of the widest product lineups on the market. But what does that mean for their accuracy?

We looked at the company’s CBD face cream, which is advertised to carry 60 mg of CBD. The sample we sent for testing came back with 80.3 mg of CBD, which is 33.8% higher.

We can cut the company some slack since 60 mg is a low CBD strength, so even a small difference in milligrams of CBD can throw off the accuracy by a large percentage.

Still, that’s not the greatest result.

The tests also showed notable amounts of other cannabinoids, confirming that this cream is made with full-spectrum hemp extract.

A88CBD Bath Salts

A88CBD is a brand owned by the Alkaline Water Company.

We sent its bath salts for third-party testing, revealing that they contained only 13.2 mg of CBD — 91.2% lower than the advertised amount of 150 mg.

That’s one of the worst results we saw out of any topical product.

However, the tests also showed notable amounts of other beneficial cannabinoids, confirming that this product is made with full-spectrum hemp extract.

Hemplucid CBDA Body Cream

Hemplucid is a reputable, established CBD company, so we had high hopes for its body cream.

One of the most potent topicals we tested, it’s supposed to contain a combined 1000 mg of CBD and its precursor compound CBDA.

However, the test results revealed an actual content of 1322.2 mg, which is 32.2% higher.

We certainly like getting over 300 mg of CBD/CBDA for free but this result is too far off the mark so it falls under our F rating.

However, the tests also showed notable amounts of other beneficial cannabinoids, confirming that this product is made with full-spectrum hemp extract.

Kushly CBD Facial Toner

Kushly is the sister brand of PureKana, a fairly well-known CBD company.

We tested its CBD facial toner, which is advertised to have 20 mg of CBD — the lowest potency out of any product in our report.

The tests showed an actual CBD content of 3.2 mg, which is 84.1% lower. That’s a disappointing result, even after considering this product’s low CBD strength.

Minted Leaf Pain Relief Cream

We haven’t tested products from Minted Leaf before, so we wanted to see how this brand measured up to the big names.

We sent its pain relief cream for third-party testing, revealing that it contained 41.9 mg of CBD (out of a total of 49 mg of cannabinoids).

Unfortunately, Minted Leaf doesn’t clearly state this cream’s CBD content. All we know is that it’s supposed to contain 150 mg of hemp extract.

In this case, we have to give the company a poor score for not providing clear information about their product.

Verified CBD Relief Rub

Verified CBD was founded by a former pharmacist, so we were hoping to see accurate CBD levels.

We tested the company’s relief rub, which should have 75 mg of CBD. However, the results showed only 15.8 mg of CBD, which is almost 80% less.

That’s one of the worst results we saw, even after accounting for the relatively low CBD strength of the product.

Smilyn CBD Salve

Smilyn Wellness is a relatively new brand out of California. It showed great results on our edibles report, so we wanted to extend our findings to the company’s topical products.

We sent Smilyn’s CBD salve for third-party testing. It should have 500 mg of CBD but our tests showed only 263.1 mg: a difference of 47.4%.

That’s almost 50% less than what it should be, which is a poor result that’s well-deserving of our F rating.
