What is CBDa? The raw form of CBD, explained
If you've ever squinted at a lab report and seen CBDa sitting next to CBD, you're not alone in wondering what it is. Short version: it's the form of CBD the hemp plant actually makes.
The plant makes the "a" version
Living hemp doesn't really produce CBD directly. It produces cannabidiolic acid — CBDa. The "a" stands for acid: CBDa carries an extra carboxyl group (a carbon, two oxygens and a hydrogen) bolted onto the CBD molecule.
Heat turns CBDa into CBD
Apply heat and CBDa loses that carboxyl group as carbon dioxide. That process is called decarboxylation ("decarbing"), and what's left is CBD. It's the same reason raw flower tests high in CBDa, while heated extracts test high in CBD.
Why lab reports list both
A certificate of analysis (COA) measures each compound separately, so you'll often see CBD and CBDa as two lines. Many labs also show a "total CBD" figure, usually worked out as CBD + (CBDa × 0.877). The 0.877 accounts for the weight lost when the carboxyl group leaves. Our guide How to read a COA in 60 seconds walks through the rest of the report.
Where you'll find it at Rooted Remedy
Our 1000mg vape pens and pods blend CBD isolate, CBDa and CBG with aromatic terpenes. We add CBDa for a fuller cannabinoid profile, not just one cannabinoid on its own. Check each batch's numbers on our lab results page.
What we won't tell you
You'll find plenty of big promises about CBDa online. We're not allowed to make health claims, and we wouldn't anyway. What we can say: it's a natural part of the hemp plant, it's chemically distinct from CBD, and it's measured on our lab reports.
