It has been a good while, I’ve had a bit of a pause, but it feels great to be testing some CBD products again. This time I’m trialling Natural Strains, a UK based brand from Liverpool. This is the first of two reviews I’ll be doing on Natural Strains, the second being on their mixed fruit bears, but first I wanted to focus on their high strength CBD oil.
What Does The Lab Test Show?
Firstly, I have to state that there was no batch code on the bottle or box, so I cannot state for certain whether it matches the batch code 281025-5 from the lab report, but the certificate of analysis is for a 6,000mg CBD oil tincture, conducted in the latter half of 2025, so I’m going to presume it’s the same batch.
Ok, so we can see from the Adact lab report that it contains 254.99mg of CBD per ml, while it’s a 30ml bottle, therefore an impressive 7,649.7mg of CBD!
On top of this, we can also see 13.86mg of CBG, which comes to 415.8mg in a full bottle. I’m a big fan of CBG, so love to see if present in a certificate of analysis. CBD and CBG are the only cannabinoids present (obviously no presence of THC in this test), making this a broad spectrum oil.
Again, assuming this COA matches the batch I have, that would provide 254.99mg of CBD in a full 1ml dropper, obviously a hefty amount, so I need to count single drops under the tongue.

You get about 20 drops from a 1ml dropper, so that makes 12.75mg per drop. During my testing period, I fluctuated up and down to see the results, going between 1 (12.7mg CBD) and 7 drops (88.9mg CBD).
Remember to take it sublingually, meaning you drop it under your tongue and hold it there for a good 45 seconds to 1 minute (depending on your patience).
I like the fact that the UK now produces 30ml bottles rather than 10ml, like it used to be, we adopted this from the Americans and I’m happy about it.
Which Carrier Oil Do They Use?
They use the gold standard (or what I personally perceive as the gold standard), MCT oil, derived from coconuts. I love MCT oil as the carrier oil for a number of reasons, firstly because it absorbs well, while it’s absorbed quite rapidly as well.
MCT doesn’t have a strong taste (some carrier oils certainly do, take my word for it), while there are a few minor fat burning benefits on top, not that the liquid level will have a huge effect here, but every little counts.
What Extraction Method Did They Use?
They use CO2 extraction on their CBD oils, which involves supercritical carbon dioxide extraction, pulling out the cannabinoids from the hemp plant, to preserve the cannabinoids and terpenes. The lab report doesn’t show terpenes so I can’t report on those figures. To be honest, most don’t, as it’s quite expensive to add the terpene report so understandably most brands don’t include this.

How Did You Sleep?
Very well thank you! I hadn’t had CBD oil for the best part of 6 weeks in the build-up to testing this, so it was nice to take some again. As always, I can’t openly state whether this had a direct connection to my sleep patterns (silly UK rules), but I can talk about how much I took and how well I slept that night.
The first night wasn’t perfect, but it’s important to remember with CBD that it has a compounding effect, by the second night I slept like a baby. I had 2 drops on day 1 and day 2. After this I did increase up to 6-7 drops per day, before the last day of testing dropping back down to 1 per day. Other than day 1, I slept really well.
How Much Does It Cost?
You can order a Natural Strains 6,000mg CBD oil bottle for £99.99, which is crazy when I think about when I entered the industry in 2019, as it would have cost you closer to £500 for 6,000mg back then. It’s great to see the prices aren’t anywhere near as steep as they used to be, making it more affordable to treat yourself.
Considering the batch showed 7,649.7mg of CBD in a full bottle, at £99.99, that would make it £0.01307 per mg of CBD…Or basically 1.3p, not bad!
