Everything you need to know about CBD, our products, dosage, lab testing and UK delivery.
CBD basics
CBD (cannabidiol) oil is a natural extract from the hemp plant blended with a carrier oil such as MCT or hemp seed oil. It is non-intoxicating and used by many people as part of a daily wellness routine.
Answer goes here.
Our CBD is extracted from industrial hemp (Cannabis sativa L.) grown for low THC content. Hemp is the same plant species as cannabis, but cultivated to legal hemp standards.
Hemp seed oil is pressed from the seeds and contains little to no CBD — it's a nutritional oil rich in omega fatty acids. CBD oil is extracted from the flowers, leaves and stalks and contains active cannabinoids.
Full spectrum contains the full range of naturally occurring cannabinoids, including trace THC within legal limits. Broad spectrum keeps the supporting cannabinoids and terpenes but has THC removed.
It's the idea that cannabinoids and terpenes work better together than in isolation. Full and broad spectrum products are formulated to preserve this synergy.
Using CBD
Place the drops under your tongue, hold for 60–90 seconds, then swallow. This sublingual method gives the fastest and most efficient absorption.
Start low and build up. Most people begin with 10–25mg per day for 5–7 days, then adjust based on how they feel. Take our Calm Leaf Quiz for a personalised starting point.
1500mg in 30ml works out to roughly 5% CBD. Each 1ml dropper contains around 50mg.
No. CBD is non-intoxicating. Our products contain THC within UK legal limits and will not produce a psychoactive 'high'.
CBD is generally well tolerated. Some people report mild effects such as drowsiness, dry mouth or changes in appetite. If anything feels off, lower the dose or stop and speak to your doctor.
CBD can interact with certain medications. If you take prescription medicine, are pregnant or breastfeeding, please check with your doctor before using CBD.
Drug tests look for THC, not CBD. Our products contain only trace THC within UK limits, but no test is guaranteed — if you're tested for work, broad spectrum or isolate options carry the lowest risk.
