Yes, Ceylon cinnamon is generally considered safe for daily use, and that's actually one of the main reasons people choose it over regular supermarket cinnamon. The difference comes down to coumarin, a compound that can harm your liver in large doses. Cassia cinnamon (the common stuff) contains up to 250 times more coumarin than Ceylon cinnamon.

Studies have shown doses of 0.5 to 3 grams of Ceylon cinnamon daily are safe for up to 6 months. But here's the thing: your safe limit depends on your body weight and which type you're using. A 70kg person can safely have about half a teaspoon of Cassia daily before hitting the coumarin threshold, while the same person could have over 18 teaspoons of Ceylon without concern.

DRUERA provides a free cinnamon intake calculator so you can figure out your exact daily limit based on your weight and cinnamon type. If you're adding cinnamon to your coffee, smoothies, or oatmeal every morning, knowing your personal number gives you peace of mind.

This is a bigger problem than most people realize. About 90% of "cinnamon" sold globally is actually Cassia, and many products don't clearly state which type you're getting. If the label just says "cinnamon" without specifying Ceylon, you're almost certainly getting Cassia.

Here's what to look for: Real Ceylon cinnamon sticks are thin, with multiple delicate layers that look like a rolled cigar. They're light tan in color, soft enough to crumble by hand, and have a mild, sweet aroma. Cassia sticks are dark reddish-brown, thick, hard, and hollow with a single layer. The flavor is different too. Ceylon tastes delicate and slightly sweet, while Cassia hits you with that intense, spicy kick.

With powder, it gets trickier since you can't see the stick structure. That's why sourcing matters. DRUERA sources directly from Sri Lanka (the only place true Ceylon cinnamon grows naturally) and provides laboratory documentation for every batch. When the label says Ceylon, you know it actually is.

Unfortunately, yes, this is a real concern. The FDA has issued multiple alerts about elevated lead levels in cinnamon products, and Consumer Reports found that 12 out of 36 cinnamon products they tested exceeded New York's safety threshold. Lead doesn't announce itself. It builds up silently in your body over time, and children absorb 4 to 5 times more than adults.

Heavy metals can enter cinnamon at multiple points: contaminated soil near industrial areas, old processing equipment, storage conditions, or even intentional adulteration to add color or weight. The scary part? You can't wash it off or cook it out once it's there.

DRUERA is the only Ceylon cinnamon supplier in the world that tests every harvest (3 to 4 times per year) for lead, arsenic, cadmium, and mercury through independent third-party laboratories, and publishes the results online. Test results consistently show lead levels well below the FDA's recommended limit of 2 ppm, with many harvests showing undetectable levels for all four heavy metals. You can view the actual lab reports for each batch on the DRUERA website, so you're seeing real numbers rather than vague "tested for purity" claims that tell you nothing.
