BioBloom CBD Oil Bottle

BioBloom CBD Oil Review

BioBloom has created its range of oils on basic principles. Top-quality hemp, manufactured using simple research-driven methods, to produce an organic and full-spectrum product. Does such simplicity deserve its top-of-the-range price tag?

Customers and retailers seem to think that it does. It often features highly on ‘Best CBD Oils’ lists and regularly receives 5 out of 5 and 10 out of 10 reviews. Its high place and loyal following seemed to come from a combination of great customer service from BioBloom and its organic certification. While these are worthy reasons to give praise, I was still expecting an average product.

In the past, I have been reluctant to buy oils from brands that could be described as ‘premium’. Too often it feels like a higher price does not guarantee top-quality oil. However, as soon I began using it, I realised that my money had been well spent.

I can say without a doubt that this is an exceptionally high-quality CBD oil. Let’s dig deeper and discover if the BioBloom 4% drops are right for you.

Who is BioBloom?

All BioBloom products are made with raw, cold-pressed, whole-plant, hemp extract. Supercritical CO2 extraction is used to separate the cannabinoids from the plant matter. They appear to believe that with this extract at the heart of their oil range, no additives or clever marketing is required. Once I had tried the oil I had to agree. This is definitely a product where the quality speaks for itself!

BioBloom produces all its products to strict organic standards. They have received full organic certification from their local organic authority. Austrian hemp is hand-harvested and processed using sustainable chemical-free methods. The whole process is pesticide and GMO-free. Does being an organic oil guarantee you a good product though?

Organic Credentials

Organic processes on their own aren’t enough to produce a great-tasting oil that will support your health and well-being. They will give you the security of knowing that the product is safe and free from chemical nasties but that’s it.

What Biobloom have done though, is create an organic oil from a crop that won the Austrian and Hungary BIO certificate, and has met the standards to receive the UK’s Biodynamic Association Certificate and the Arge-Canna seal of quality. They’ve valued that natural product and presented it in a pure manner that respects and showcases its natural origins.

That, in my opinion, has resulted in a particularly potent and effective oil.

Unfortunately, the flip side of this is that a natural substance does not always lend itself to being easily packaged. It also doesn’t guarantee you a flavour that you want to savour or even hold under your tongue for the 60 seconds advised on the label!

Because of its simple ingredient list. BioBloom CBD oil contains 45% whole-plant hemp extract suspended in 55% hemp oil, it is at best ‘natural’ and at worst like burying your face in fermenting hay. However, as always, I embraced it as a 100% natural and vegan product that should be embraced, held my nose and swallowed.

Third-Party Lab TestsBioBloom CBD Oil Lab Results

As with many brands, BioBloom makes some strong claims about the purity and provenance of its products. When selecting this oil, I looked for third-party lab tests to see if the claims could be verified.

One certificate is accessible from the product page alongside other relevant documents. My batch number is LB04/005 and I was able to view the matching set of lab results. The collection of available lab documents showed a profile of the cannabinoids, a profile of terpenes and a contaminant screening that demonstrated that the sample was toxin-free. Disappointingly the analysis showed that it contained 3.2% CBD and not the 4% on the bottle.

As I looked further, I could see that the lab had calculated the CBD and CBDa together as 4.31%. While this does show why the oil is referred to as 4%, it could be made clearer as the bottle states 4% CBD and not 4% CBD + CBDa.) However, the site I purchased from does make it clear that it is a combination of CBD and CBDa so it is an annoyance more than anything.

The cannabinoid profile backs up that it is made with full-spectrum extract and shows a range of 9 cannabinoids, including CBDV, CBG, CBGa and Delta-9-THC. The amount of Δ9-THC was recorded as 0.08%, which is only a tiny trace but does work out at 8mg which is above the UK legal limit of 1mg per container.

The third-party lab results show that this is, without a doubt, a high-quality oil, and I’ve personally experienced its potency; however, there are a few areas that need improvement for it to receive a higher score in this area.

Ease of UseBioBloom CBD Oil Dropper

While this is a good oil its natural ingredients have given it a thick viscous quality that makes use and storage difficult. Previous versions of this product regularly leaked because the oil tended to get into the thread of the lid causing it to open spontaneously. Thankfully, that’s no longer an issue, the bottle closes well and is as close to leakproof as you’re likely to get.

The bulb-tipped dropper is relatively easy to use but it would benefit from a scale down the side to assist with measuring out a precise amount. I found that placing the drops under your tongue next to a mirror helps to improve accuracy.

While you don’t get a child-safe cap with this oil, it’s simple and relatively easy to use, even on the go.


You can probably guess my feelings on this one already. The combination of the whole plant extract and the hemp seed oil has created an earthy and intense flavour. It isn’t too bad under your tongue but as you swallow it there is a strong bitter aftertaste.

It’s a good idea to have a drink ready to wash it down.  If combining oils with strong-tasting, savoury edibles is your thing, this one is a good choice. Once combined with other strong flavours, to dilute the intensity, it adds a pleasant bass note which goes well with sharp and salty foods. If you prefer a milder flavour check out our reviews for the Cibdol 4% and Bud & Tender 1000mg.

BioBloom Potency/ Effectiveness

Even though this is a 4% oil its potency had more in common with stronger oils from other brands. Letting it rest under my tongue for 60 seconds before swallowing resulted in a calm and grounded feeling about ten minutes later.

When swallowing the recommended dose, I felt a relaxing effect at just over 30 minutes and could feel it lasting for a decent four hours. I found that it worked best for me if I used it to relax or calm down when I felt a bit tense.

Value for Money

Costing only £23.90 this is a premium oil at a relatively affordable price point. It works out at about 6p per mg of CBD which makes it cheaper than the excellent Bud & Tender (7p per mg) and CannaWell (7.5p per mg). However, it’s still significantly more expensive than budget options like Access CBD (1.4p per mg) and Vitality CBD (1.7p per mg).

Because this is an oil that is made entirely from hemp products and contains a large amount of whole-plant extract, you get a lot of hemp for your money. This does affect the taste but that taste tells you, you are getting what you’ve paid for.

Would I Buy it Again?

Yes, I would buy this oil again. The price is excellent and it was highly effective, the oil is certified organic and I found it to be very effective. As a result, it scores highly enough to be included in our best UK CBD oils article where the bar is set very high. Also, we consider it to be one of the best products in our organic CBD oil reviews article.

If what you seek is a high-strength oil, at 4% it is a long way off the threshold of 25% to be included in our list of the strongest CBD oils available in the UK.
