Ceylon Cinnamon NZ: The Truth About Coumarin, Quality & Why Not All Cinnamon Is Created Equal

Walk into any New Zealand supermarket and grab a jar of cinnamon off the shelf. Chances are, it isn't actually cinnamon — not the real kind, anyway. What you're most likely holding is Cassia, a related but distinctly different spice that's cheaper, harsher, and high in a compound called coumarin that you really don't want in large amounts.

Real cinnamon — Ceylon cinnamon, also called Cinnamomum verum or "True Cinnamon" — is something else entirely. Sourced from the inner bark of trees grown in Sri Lanka, it has a delicate, floral sweetness, a fraction of the coumarin content, and a nutritional profile that has made it one of the most studied spices in the world.

This guide goes deeper than any other cinnamon article in NZ. We cover the science behind coumarin, what the research actually says about Ceylon's health benefits, how to tell if you're being sold Cassia, and why SpiceBloom's Organic Ceylon Cinnamon is a different product entirely from what's sitting on your supermarket shelf.

The 4 Types of Cinnamon — and Why Only One Is "Real"

Most people don't know there are actually four commercial varieties of cinnamon, all from different species of the same plant family. Only one is considered true cinnamon.

Type	Species	Origin	Coumarin Level	Flavour
Ceylon ("True Cinnamon")	Cinnamomum verum	Sri Lanka	~0.004% — extremely low	Sweet, floral, delicate, citrus-like
Saigon / Vietnamese Cassia	Cinnamomum loureiroi	Vietnam	~0.22% — very high	Intensely spicy, almost burning
Chinese Cassia	Cinnamomum aromaticum	China	~0.31% — very high	Harsh, woody, pungent
Korintje / Indonesian Cassia	Cinnamomum burmanii	Indonesia	~0.07% — moderate-high	Mild but still coarser than Ceylon

To put those numbers in perspective: Ceylon contains up to 75 times less coumarin than Chinese Cassia. If you're using cinnamon every day — in your morning oats, coffee, smoothie, baking — that difference matters enormously.

What Is Coumarin and Why Should You Care?

Coumarin is a naturally occurring aromatic compound found in many plants. In small amounts it's harmless. In large or repeated doses, it can cause liver toxicity and is classified as a potential carcinogen by the European Food Safety Authority (EFSA).

The EFSA has set a tolerable daily intake (TDI) of 0.1 mg of coumarin per kilogram of body weight. For a 70kg adult, that's 7mg per day. Here's why that matters in practice:

• One teaspoon (2.6g) of Chinese Cassia powder contains approximately 8mg of coumarin — already over the daily limit for a 70kg adult
• One teaspoon of Ceylon cinnamon contains approximately 0.1mg of coumarin — well within safe limits even in large culinary amounts

This is why health authorities in Germany, the UK, and across the EU have issued specific warnings about heavy daily consumption of Cassia cinnamon — and why Ceylon is the only variety officially recommended for daily therapeutic use.

If you add cinnamon to your oats, smoothie, and coffee every morning, you want Ceylon. Full stop.

Does Organic Ceylon Cinnamon Actually Make a Difference?

Short answer: yes — and here's the honest breakdown of why.

The organic certification means the cinnamon trees are grown without synthetic pesticides, herbicides, or chemical fertilisers. When you're using a spice daily — sometimes multiple times a day — you're consuming cumulative trace residues from whatever was sprayed on the crop. Organic eliminates that risk entirely.

Beyond the safety aspect, organic farming practices also tend to produce more flavonoid-rich spice. Research shows plants grown organically often develop higher concentrations of protective phytochemicals (their natural defence compounds) because they aren't relying on chemical inputs. In cinnamon, this translates to a deeper, more complex flavour and stronger antioxidant activity.

SpiceBloom's Organic Ceylon Cinnamon is sourced from certified organic farms in Sri Lanka — the only country in the world considered the true home of Cinnamomum verum. If you want the maximum benefit from daily cinnamon use, organic Ceylon from Sri Lanka is the definitive choice.

7 Science-Backed Health Benefits of Ceylon Cinnamon

1. 🩸 Blood Sugar Regulation — The Most Studied Benefit

Ceylon cinnamon contains compounds that mimic insulin and improve insulin sensitivity at the cellular level. Multiple peer-reviewed studies have found that regular cinnamon consumption can meaningfully reduce fasting blood sugar levels in people with type 2 diabetes or insulin resistance. The key compounds responsible are cinnamaldehyde and proanthocyanidins — both found in significantly higher concentrations in Ceylon than in Cassia, and both preserved when cinnamon is cold-milled rather than heat-processed.

2. 🔥 Powerful Anti-Inflammatory Action

Chronic low-grade inflammation is now recognised as an underlying driver of most modern diseases — from heart disease to Alzheimer's. Ceylon cinnamon's cinnamaldehyde actively inhibits inflammatory proteins including NF-kB, one of the primary inflammation signalling pathways in the body. Its anti-inflammatory profile is comparable to ibuprofen in some in-vitro studies — without the gastrointestinal side effects.

3. 🧠 Cognitive Protection and Brain Health

Two compounds in Ceylon cinnamon — cinnamaldehyde and epicatechin — have been shown in research to inhibit the aggregation of tau proteins in the brain. Tau protein aggregation is one of the hallmarks of Alzheimer's disease. While more human trials are needed, the preliminary science is compelling enough that cinnamon is now being seriously studied as a neuroprotective food.

4. 💓 Heart Health and Cholesterol

Regular Ceylon cinnamon consumption has been linked in clinical studies to reductions in LDL cholesterol and triglycerides, while maintaining or slightly increasing HDL (the "good" cholesterol). The polyphenols in Ceylon cinnamon also support arterial elasticity, reducing blood pressure over time.

5. 🦠 Broad-Spectrum Antimicrobial

Cinnamon's essential oils — particularly cinnamaldehyde and eugenol — are strongly antimicrobial. Research has shown effectiveness against Listeria, E. coli, Salmonella, and even some strains of Candida albicans. This is why cinnamon has historically been used in food preservation and why it's a traditional remedy for gut infections.

6. 🌿 Digestive Support

Ceylon cinnamon stimulates the secretion of digestive enzymes, supports healthy bowel motility, and reduces gas and bloating. A small cup of cinnamon tea after a heavy meal is one of the oldest and most well-validated digestive remedies across Ayurvedic, Chinese, and European herbal traditions.

7. ⚡ Antioxidant Potency — Ranking Among the Highest of Any Food

In ORAC (Oxygen Radical Absorbance Capacity) testing, cinnamon consistently ranks among the top 10 most antioxidant-rich foods on earth — above blueberries, dark chocolate, and most leafy greens. These antioxidants neutralise free radical damage linked to cancer, accelerated ageing, and metabolic disease.

How to Tell If Your Cinnamon Is Fake (Cassia Test at Home)

This is one of the most useful things you can know as a consumer — and almost no NZ article covers it. Here are three easy ways to check:

🔍 The Scroll Test (for quills/sticks)

Break a cinnamon quill in half and look at the cross-section. Ceylon quills are tightly rolled with multiple thin, papery layers — like a rolled newspaper. Cassia quills have a thick, single-layer roll or a hollow curl. If the cut end looks like a single thick ring, it's Cassia.

🎨 The Colour Test

Ceylon cinnamon powder is a light tan-brown colour — almost like a warm sand. Cassia is much darker — a deep reddish-brown. If your "cinnamon" looks like dark chocolate, it's almost certainly Cassia.

🧪 The Iodine Test

Mix a small amount of cinnamon powder in water and add a drop of iodine solution. Ceylon cinnamon will turn only slightly brown-blue, indicating low starch content. Cassia will turn a deep, dark blue-black because of its higher starch content. This test is used by food scientists and is genuinely reliable.

👅 The Taste Test

True Ceylon cinnamon dissolves easily on the tongue and leaves a sweet, slightly citrusy, mild warmth. Cassia has a harsh, spicy, almost burning quality. If your cinnamon makes your mouth tingle uncomfortably, it's Cassia.

Organic vs. Premium (Non-Organic) Ceylon: Which Should You Choose?

Feature	🌿 Organic Ceylon Cinnamon	⭐ Premium Ceylon Cinnamon
Cinnamon Type	100% Cinnamomum verum (True)	100% Cinnamomum verum (True)
Certified Organic	✅ Yes	❌ No (conventional farming)
Pesticide-Free	✅ Certified	Not certified
Origin	Sri Lanka 🇱🇰	Sri Lanka 🇱🇰
Best For	Daily health use, children, pregnancy	Everyday cooking & baking
Price From	NZD $9.95 / 100g	NZD $4.59 / 50g

Our recommendation: If you're using cinnamon primarily for health and wellness — daily in drinks, supplements, or as a therapeutic spice — choose Organic Ceylon. If you're using it predominantly in baking and cooking where the amounts are smaller and organic certification isn't a priority, Premium Ceylon is excellent value.

How Much Ceylon Cinnamon Should You Take Per Day?

This is something no other NZ cinnamon guide covers properly, so let's be specific:

• General wellness: ½ to 1 teaspoon (1–2.5g) per day is well-supported by research and considered very safe with Ceylon
• Blood sugar support: Studies showing significant effects used 1–3g per day (½ to 1.5 tsp), taken with meals
• Culinary use: There's no meaningful upper limit for Ceylon in normal cooking — its coumarin level is so low that you'd need to eat many tablespoons daily before approaching any concern
• Children: Small culinary amounts (a sprinkle on oats or in baking) are completely safe. Therapeutic doses should be discussed with a GP
• Pregnancy: Normal culinary use is safe. Avoid large therapeutic doses during pregnancy

Compare this to Cassia: European health authorities advise against consuming more than ½ teaspoon of Cassia daily for adults due to coumarin. For children, the safe limit is lower still.

Frequently Asked Questions: Ceylon Cinnamon in NZ

Is the cinnamon at Countdown/New World/Pak'nSave actually Ceylon?

Almost certainly not. The vast majority of supermarket cinnamon in NZ — regardless of brand — is Cassia, usually from Vietnam or China. It may simply say "cinnamon" with no further detail. True Ceylon will always be labelled with its origin (Sri Lanka) and the term "Ceylon" or "True Cinnamon." If the label doesn't specify, assume it's Cassia.

Can I use Ceylon cinnamon if I'm diabetic?

Ceylon cinnamon is one of the most studied natural interventions for blood sugar management. Many people with type 2 diabetes or insulin resistance include it as part of their daily routine. That said, it should complement — not replace — your prescribed medication and dietary plan. Always speak to your doctor before making changes to your diabetes management.

Does Ceylon cinnamon expire?

Stored correctly (cool, dry, away from light and moisture), Ceylon cinnamon powder stays fresh and potent for 2–3 years. Quills can last even longer — up to 4 years. Always reseal tightly after opening.

Is Ceylon cinnamon safe for dogs?

Yes — in very small amounts, Ceylon cinnamon is considered safe for dogs and is sometimes used in pet treats. Cassia cinnamon in larger amounts is not recommended for pets. As always, consult your vet before introducing anything new to your pet's diet.

Where is the best place to buy Ceylon cinnamon in NZ?

For quality you can trust, SpiceBloom is NZ's go-to source — both Organic Ceylon Cinnamon Powder and Premium Ceylon Cinnamon Powder are sourced directly from Sri Lanka, packed fresh weekly in Auckland, and shipped fast across New Zealand.

What's the difference between Ceylon cinnamon powder and quills?

Same spice, different form. Powder blends seamlessly into drinks, smoothies, and baked goods. Quills are better for slow infusions — teas, mulled wine, poached fruits, rice dishes, and stocks — where the whole bark gradually releases its oils. Many people keep both.
