How We Ensure Every Calm Leaf Product is Lab-Tested
When it comes to choosing CBD, trust is everything. With so many products on the market, it can be difficult to know which ones are safe, legal, and truly effective. At Calm Leaf, we believe transparency is key — that’s why every single product we sell is lab-tested before it reaches your hands.
Here’s how we make sure you always get premium CBD flower UK customers can rely on.
Why Lab Testing Matters
Not all CBD products are created equal. Without proper testing, you risk buying something that:
❌ Contains higher levels of THC than legally allowed
❌ Has little or no CBD despite the label
❌ May include pesticides, mould, or heavy metals
Independent lab testing ensures every product is safe, compliant, and exactly what it claims to be.
Independent Third-Party Testing
At Calm Leaf, we don’t just rely on our own checks. We work with accredited third-party laboratories to test every batch of our CBD flower. These labs examine:
🧪 Cannabinoid profile – accurate levels of CBD and THC
🌿 Purity – free from harmful chemicals or contaminants
🌸 Consistency – ensuring every strain meets our strict quality standards
This gives you confidence that what’s on the label is exactly what’s in the product.
Certificates of Analysis (COAs)
We believe our customers deserve full transparency. That’s why we provide Certificates of Analysis (COAs) for our products. These easy-to-read lab reports clearly show:
CBD content
THC levels (always within UK law)
Proof of quality and compliance
It’s just another way we show our commitment to being a trusted UK CBD supplier.
