10 Best Cinnamon Supplements In 2025

Cinnamon supplements offer an easy way to support blood sugar control, reduce post-meal glucose spikes, and manage sugar cravings. They may also help improve insulin sensitivity or maintain metabolic balance.

Many supplements use either Ceylon cinnamon (Cinnamomum verum), a milder, low-coumarin option, or Cassia cinnamon (Cinnamomum cassia), which is more concentrated but may pose safety concerns with long-term use due to higher coumarin levels.

These products come in capsules, powders, softgels, or liquid extracts, and many include added ingredients like chromium, berberine, or alpha-lipoic acid to enhance blood sugar and insulin support.

In this guide, you’ll find 10 of the best cinnamon supplements available today, carefully selected based on ingredient transparency, third-party testing, brand credibility, and user feedback.

Side Effects Of Cinnamon Supplements

1. Liver Health Considerations

   Taking cinnamon supplements made from Ceylon cinnamon generally poses less risk of liver toxicity than Cassia due to its much lower coumarin content. However, coumarin, even in small amounts, is metabolized by liver enzymes such as cytochrome P450. High or prolonged intake might strain liver function, especially if you have preexisting liver disease. Although Ceylon cinnamon’s coumarin levels are minimal, consistent supplementation could still impact liver enzyme activity or cause mild liver stress.

2. Blood Sugar Effects and Hypoglycemia Risk

   Adding cinnamon supplements to your routine might boost insulin sensitivity and potentially decrease blood glucose levels by aiding in glucose uptake in cells and modulating insulin receptor activity. However, taking these supplements along with prescribed diabetes medications could increase the risk of hypoglycemia (dangerously low blood sugar). The bioactive compounds, such as polyphenols and cinnamaldehyde, in these products support blood sugar regulation but may amplify the effects of antidiabetic drugs. Therefore, it’s important to monitor blood glucose regularly and discuss supplementation with your doctor to avoid unwanted blood sugar drops or dizziness caused by hypoglycemia.

3. Allergic Reactions

   Cinnamon supplements might cause allergic responses, though this is uncommon with Ceylon cinnamon. The spice contains cinnamaldehyde and eugenol, compounds known to provoke immune reactions. These reactions include skin rashes, itching, or respiratory symptoms like wheezing and nasal congestion. Ingesting cinnamon in supplement form can also cause oral allergy syndrome, resulting in itching or swelling of the lips, mouth, or throat.

4. Digestive Sensitivity

   Adding Ceylon cinnamon supplements to your daily intake may sometimes cause mild digestive discomfort, such as nausea, stomach cramps, or acid reflux. This happens because cinnamaldehyde and other volatile oils in cinnamon can mildly irritate the gastrointestinal mucosa, especially if taken on an empty stomach. While Ceylon cinnamon tends to be gentler than Cassia, its bioactive compounds still stimulate gastric secretions and motility, which might upset sensitive digestive systems.

5. Oral and Throat Sensations

   Taking cinnamon supplements in concentrated powder or extract form may produce a mild burning or tingling sensation in your mouth or throat. This occurs because cinnamaldehyde, the primary essential oil in cinnamon, activates sensory receptors that detect irritants. Although Ceylon cinnamon has a lower cinnamaldehyde concentration than Cassia, if you are sensitive, you may experience this warming or tingling effect. In some cases, this sensation can trigger mild inflammation or discomfort in mucous membranes, especially if you have acid reflux or oral sensitivity.

How Did We Evaluate Cinnamon Supplements?

1. Brand Reputation

   We factored in each company’s standing with independent review platforms to assess trust, transparency, and long-term consumer satisfaction. In particular, we analyzed Better Business Bureau (BBB) ratings and Trustpilot scores to measure overall brand credibility.

   Nature’s Bounty holds an A+ rating from the Better Business Bureau (BBB), indicating a long-standing reputation for reliable customer service and consistent business practices. Although it doesn’t have a presence on Trustpilot, its established history and widespread availability support its credibility in the cinnamon supplement category.

   Similarly, Natural Factors also earns an A+ BBB rating and is known for research-backed formulations and strict quality standards.

   Carlyle holds an A-rating on the BBB, reflecting generally positive customer interactions and dependable business conduct. Horbaach also holds an A-rating on the BBB, suggesting stable operations and a reasonable level of trustworthiness. While neither brand has a Trustpilot profile, their BBB scores offer some assurance of credibility.

   CleanNutra stands out for its 3.8/5 Trustpilot rating based on 600+ reviews. Though not listed on the BBB, this level of user feedback suggests moderate customer satisfaction and a reasonably active support system, making it a mid-tier but transparent option.

   Nutricost, with a B+ BBB rating and no Trustpilot presence, ranks slightly lower. It has decent credibility but lacks consistent consumer visibility across review platforms.

   Puritan’s Pride receives a 1.4/5 on Trustpilot based on over 200 reviews, by far the lowest among all reviewed brands.

   On the other hand, Nature’s Nutrition, Nutra Harmony, and Piping Rock Super do not currently have Trustpilot reviews or BBB ratings, making it difficult to assess their reputation or accountability.

2. Value For Money

   We compared the cost per capsule alongside quality indicators like cinnamon type, dosage, added ingredients, and potential third-party testing to identify real value.

   Nutricost offers the best value with 240 capsules for $17.97 ($0.075 each), making it highly economical. Carlyle follows closely with 120 Ceylon cinnamon capsules for $9.99 ($0.083 each), delivering rare affordability for true cinnamon. Horbaach also stands out with 150 Ceylon capsules at $14.23 ($0.095 each), striking a strong balance between type and cost. Nature’s Bounty offers 100 capsules for $9.49 ($0.095).

   Piping Rock provides a good blend of price and added value with 120 Ceylon-based complex capsules at $14.59 ($0.12 each). Puritan’s Pride, at $7.79 for 60 capsules ($0.13 each), includes chromium, offering functional support beyond basic cinnamon. Nature’s Nutrition charges $18.92 for 120 capsules (~$0.16 each), a bit pricier but potentially backed by third-party testing, which may appeal to more cautious buyers.

   Nutra Harmony’s Ceylon cinnamon costs $19.89 for 60 capsules ($0.33 each), offering fair but unremarkable value. Natural Factors’ WellBetX comes in at $20.95 for 60 capsules ($0.35 each), priced higher likely due to standardization or added support claims. CleanNutra ranks lowest in value with 60 Ceylon capsules for $39.95 (~$0.67 each), nearly double the cost of mid-range alternatives without clear justification.

Frequently Asked Questions

1. Which type of cinnamon is safest for long-term use?
   Ceylon cinnamon (Cinnamomum verum) is considered safer for long-term use due to its low coumarin content. Cassia cinnamon, although more common and potent, can raise liver toxicity risks with chronic use.
2. Are there any risks of liver damage from cinnamon supplements?
   Yes. Cassia cinnamon has high coumarin content, which may be hepatotoxic in large doses or with prolonged use. Ceylon cinnamon is preferred for people concerned about liver health.
3. Can cinnamon supplements help reduce sugar cravings?
   Cinnamon may help reduce sugar cravings by moderating blood glucose fluctuations, which can stabilize appetite and prevent rebound hunger caused by post-meal glucose spikes.
4. Is cinnamon extract more effective than ground cinnamon capsules?
   Cinnamon extracts standardize active compounds like cinnamaldehyde and polyphenols, offering more consistent potency than ground bark. This can result in more predictable therapeutic effects in clinical applications.
5. Why do some cinnamon supplements include chromium?
   Chromium is often paired with cinnamon to enhance glucose metabolism. The combination may offer synergistic effects on insulin function, but it requires careful dose balancing.

Final Words

Cinnamon supplements offer a natural way to support blood sugar regulation, metabolic function, and antioxidant defense, especially if you’re looking for gentle, plant-based support.

However, while many of the products featured in this list offer quality sourcing, thoughtful formulations, and third-party testing, results can vary from person to person.

It’s important to remember that cinnamon, particularly in doses exceeding 3 grams daily or when derived from Cassia, may contain elevated levels of coumarin that could impair liver enzyme function and increase hepatotoxic risk with long-term use.

If you have liver concerns or are on blood-thinning medications, speak with your healthcare provider before starting any supplement. Even Ceylon cinnamon, which is considered safer, isn’t entirely risk-free, especially when combined with other metabolic enhancers like chromium or berberine. Factors like your current blood sugar levels, digestive tolerance, and medication routine should guide your decision.

Cinnamon supplements can complement your wellness routine, but they aren’t a standalone solution. Always aim for a balanced diet, consistent physical activity, and medical guidance alongside supplementation.
