Experienced CBD Users
If you use CBD oil regularly and find that lower concentrations — 10%, 20%, or 30% — are no longer meeting your needs, our 40% oil provides the next level of potency without increasing the volume of oil you need to take.

What Is Valley CBD 40% Broad Spectrum CBD Oil?
Our 40% broad spectrum CBD oil is one of the highest-concentration CBD oils legally available in the UK. The 40% figure refers to the proportion of pure CBD extract within the total liquid — meaning 40% of every drop is active CBD.
In a single 30ml bottle this delivers 12,000mg of total CBD. At approximately 20mg per drop, even experienced users need very few drops per dose — making each bottle extraordinarily long-lasting and excellent value per milligram.
Formulated with premium MCT (medium-chain triglyceride) oil as the carrier, our formula offers superior absorption compared to hemp seed oil alternatives. MCT oil enhances the rate at which CBD is taken up through sublingual tissue, ensuring more reaches your bloodstream from every drop.
Unlike many ultra-potent oils, ours has been specially formulated to remove the bitter, harsh aftertaste common in high-concentration CBD — making it pleasant to take every single day.

What makes broad spectrum different from full spectrum or isolate?
Broad spectrum CBD oil retains the full range of cannabinoids, terpenes, and plant compounds naturally found in hemp — but with all THC completely extracted and removed. This gives you the entourage effect (where multiple cannabinoids work together more effectively than CBD alone) without any trace of THC, making it the preferred choice for those who require absolute confidence in a 0.0% THC result.

Who Should Use High Strength Broad Spectrum CBD Oil?
Our 40% broad spectrum CBD oil is designed for a specific type of user. Because of its exceptionally high potency, it is most suitable for those with prior CBD experience — or those with specific needs requiring a higher daily milligram intake.
High-Demand Lifestyles
Athletes, physical labourers, and individuals managing high-stress environments often require a higher daily CBD intake. Our maximum-strength broad spectrum formula is built for those with demanding recovery and wellness needs.
Value-Conscious Buyers
At 40% concentration you need far fewer drops per dose than with lower-strength oils. The cost-per-milligram of CBD is significantly lower than buying multiple bottles of 10% or 20% oil — making this the smart long-term choice.
How To Use
Dosing Guide: 40% High Strength CBD Oil
Each drop contains approximately 20mg of CBD. Start with a single drop and adjust gradually over 1–2 weeks until you find your optimal daily amount. Always place drops under the tongue for maximum absorption.
| Goal | Drops | CBD |
|---|---|---|
| General Wellness & Daily Balance | 1 drop | ~20mg |
| Stress Relief & Chronic Support | 2 drops | ~40mg |
| Deep Sleep & Recovery | 3 drops | ~60mg |
| Maximum Strength Dose | 4–5 drops | 80–100mg |
FSA Guidance: The UK Food Standards Agency recommends a maximum of 10mg CBD per day for healthy adults. Consult your GP before use if you are pregnant, breastfeeding, or taking prescription medication.
01
Place Under the TongueUse the pipette to drop oil directly beneath your tongue onto the sublingual tissue, where capillaries allow rapid absorption into the bloodstream.
02
Hold for 60–90 SecondsDon't swallow immediately. Holding the oil under your tongue for at least 60 seconds significantly improves absorption compared to swallowing straight away.
03
Take Consistently DailyCBD works best with regular use. Many users prefer mornings for focus and energy, or evenings for sleep and recovery support.
04
Start Low, Go SlowNew to 40% strength? Begin with one drop (20mg) and wait 7–10 days before increasing. Everyone's endocannabinoid system responds differently.
What Makes Valley CBD's 40% Broad Spectrum Oil Different?
Not all high strength CBD oils are equal. The quality of source hemp, the extraction method, and the carrier oil all determine how effective — and how safe — the final product is. Here's what sets Valley CBD apart.
Organic Hemp Source
Our CBD is extracted from organically cultivated hemp grown without pesticides, herbicides, or synthetic fertilisers — ensuring the cleanest possible starting material for our high strength oil.
Supercritical CO₂ Extraction
We use supercritical CO₂ extraction — the gold standard in the industry. This solvent-free process preserves the full range of cannabinoids and terpenes that make our broad spectrum formula effective.
Third-Party Lab Tested
Every batch is independently tested by an accredited laboratory. Results verify CBD potency, confirm 0.0% THC, and screen for heavy metals, pesticides, and microbial contamination. Certificates available on request.
Premium MCT Carrier Oil
MCT oil (coconut-derived) is chosen for its superior bioavailability. It significantly enhances CBD absorption compared to hemp seed oil, meaning more CBD reaches your system from every single drop.
FSA Compliant
Fully compliant with UK Food Standards Agency guidelines and produced in a GMP-certified facility. You can take Valley CBD's 40% oil with complete confidence in its safety and legality.
No Harsh Aftertaste
Specially formulated to remove the bitter, grassy aftertaste common in ultra-high-potency CBD oils. Smooth, natural tasting, zero-calorie, and keto-friendly — a pleasure to take every day.

40% Broad Spectrum CBD Oil — FAQs
Broad spectrum CBD oil contains CBD alongside a wide range of other naturally occurring cannabinoids (such as CBG, CBC, and CBN) and terpenes — but with all THC completely removed. This allows you to benefit from the entourage effect of multiple cannabinoids working synergistically, without any THC content whatsoever.
40% CBD oil means that 40% of the total liquid in the bottle is pure CBD extract. In a 30ml bottle, this equates to 12,000mg of total CBD — one of the highest concentrations available in the UK.
Each drop of our 40% broad spectrum CBD oil contains approximately 20mg of CBD. A full 30ml bottle contains approximately 600 drops and 12,000mg of total CBD.
Yes. Our 40% broad spectrum CBD oil is fully legal in the UK. It contains 0.0% THC, is FSA compliant, and is produced from legally cultivated industrial hemp. It is sold and regulated as a food supplement.
