Turmeric is having a moment. Functional food brands are adding it to everything from oat milk to face serums, and the global turmeric market is projected to surpass $5 billion by 2027. But behind the golden hype is a real and meaningful variable that most buyers ignore: curcumin content.
What Is Curcumin?
Curcumin is the primary bioactive polyphenol in turmeric root. It accounts for around 70–80% of the curcuminoid complex — the group of compounds responsible for turmeric's yellow-orange pigment and most of its purported anti-inflammatory properties.
Why Curcumin Content Varies
Raw turmeric root contains curcuminoids typically in the range of 1%–5% by dry weight, depending on variety, soil mineral profile, harvest timing, and drying method. The loamy, well-drained soils of Kegalle and Sabaragamuwa in Sri Lanka produce particularly high readings.
Our Numbers
Our Sri Lankan turmeric consistently tests at 4.2%–5.1% curcuminoids by dry weight, verified by third-party HPLC analysis. Commodity-grade Indian turmeric often tests at 2%–3%. View our Turmeric or contact our team for batch-specific COAs.
Bioavailability: The Piperine Connection
Curcumin has notoriously low bioavailability when consumed alone. Co-administration with piperine (the active compound in black pepper) increases absorption by up to 2,000% by inhibiting hepatic glucuronidation — which is why traditional Sri Lankan cuisine has always combined turmeric and black pepper.
