Cinnamon
An honest look at the most-asked-about kitchen spice, and the gap between clinical doses and a cup
No tea cures or treats diabetes, and cinnamon is not a substitute for medication. That said, cinnamon is one of the more researched kitchen spices: pooled trials have linked it to a modest reduction in fasting blood glucose, at gram-scale doses far above a cup of tea, and it has antioxidant and antimicrobial research interest too. Sippo Stay Awhile is a warm, cinnamon-led cup to enjoy as part of a balanced lifestyle, honestly described.
Cinnamon is the kitchen spice people ask about most, usually because of the diabetes question, so let's answer it honestly up front: no tea cures or treats diabetes, and cinnamon is not a replacement for medication. With that clear, cinnamon is genuinely one of the more researched culinary spices, and Stay Awhile is a warm, cinnamon-led cup, so here is the measured version.

What's inside, and why
Found in: Stay Awhile teaEmergingCinnamomum
The star. Pooled trials have linked cinnamon to a modest reduction in fasting blood glucose, with a smaller, inconsistent effect on longer-term markers (Allen et al., 2013; Akilen et al., 2012), plus antioxidant and antimicrobial research interest. Those trials used gram-scale doses, far more than a cup of tea, so we cite the research, not a promise.

Real dried apple gives the cup a natural, baked-apple sweetness with no added sugar, the comforting body of the blend.
Found in: Stay Awhile teaTraditionalSyzygium aromaticum
A whisper of warm clove, rich in eugenol, rounds out the cinnamon with depth and a traditional spiced character.

A soft, sweet, toasted note that makes the cup unmistakably Stay Awhile, balancing the warming spice.

Cinnamon is one of the more researched kitchen spices. Pooled trials have linked it to a modest reduction in fasting blood glucose (Allen et al., 2013; Akilen et al., 2012), and it has antioxidant and antimicrobial research interest. Honestly though, those trials used gram-scale standardised doses, far more than a cup of tea, so we describe cinnamon as a researched and delicious spice, not a treatment for anything.
No tea cures or treats diabetes, and cinnamon is not a substitute for diabetes medication or medical advice. Research is interested in cinnamon and blood-sugar response, but at concentrated doses and with inconsistent effects on long-term markers, and a cup of tea is not a clinical dose. We cover this fully in our cinnamon and blood sugar guide. Never change a prescription based on a tea.
For most people a cinnamon tea is a gentle everyday drink. Cassia cinnamon contains coumarin, best not consumed in very large amounts, but a normal cup is fine. If you are pregnant, on medication or managing a condition, check with your doctor.
Warm and cosy: real cinnamon and clove, baked-apple sweetness, and a soft toasted-coconut twist. Comforting rather than spicy-hot, with only a gentle lift from a touch of green tea.
Cinnamon, honestly
Cinnamon and blood sugar is the question that brings most people to cinnamon tea, so let's answer it honestly: no tea cures or treats diabetes, cinnamon is not a substitute for medication or medical advice, and you should never manage blood sugar with a cup of tea. With that boundary set, the research is still genuinely interesting.
Cinnamon is one of the more studied culinary spices. Pooled analyses have linked it to a modest reduction in fasting blood glucose, with researchers interested in its polyphenols and their effect on glucose handling (Allen et al., 2013; Akilen et al., 2012). It also has antioxidant and antimicrobial research interest. It is a real, if modest, signal that has held attention for over a decade.
Here is the honest gap. Those trials used gram-scale standardised cinnamon, often the equivalent of a teaspoon or more of concentrated extract daily over weeks, and even then the effect on longer-term markers was small and not consistently significant. Stay Awhile is a balanced spiced cup in which cinnamon is the lead flavour, not a measured dose. So it is a tea built on a researched ingredient, not a blood-sugar intervention.
Enjoy Stay Awhile as a warm, comforting, no-added-sugar cup you genuinely like, as part of a balanced lifestyle. Swapping a sugary hot drink for an unsweetened cinnamon cup is a small, real upgrade. If blood sugar is something you manage, keep working with your doctor and mention cinnamon to them, since it can interact with some medicines. For that question specifically, our cinnamon and blood sugar guide goes deeper.

Pooled trials found cinnamon was associated with a modest reduction in fasting glucose, with a smaller, inconsistent effect on HbA1c. Trials used gram-scale cinnamon doses, far more than a spiced tea contributes; cited for the ingredient's research interest only.
Akilen, R., Tsiami, A., Devendra, D., & Robinson, N. (2012). Cinnamon in glycaemic control: Systematic review and meta-analysis. Clinical Nutrition, 31(5), 609-615. https://doi.org/10.1016/j.clnu.2012.04.003
Pooled trials found cinnamon was associated with improved glycaemic control. Trials used gram-scale doses far above a spiced cup, and effects on HbA1c were not consistently significant, so framed as research interest, never a treatment.
