Ingredients & botanicals
What is actually in the cup — collagen, black tea, the warming spices and botanicals — and what the research says about each.
Chai Spices
- Cardamom: Digestion, Blood Pressure, and the Queen of SpicesCardamom is prized for its aroma and traditional use as a digestive — and trials link it to modest blood-pressure and metabolic effects. Here’s the evidence.
- Cinnamon: Cassia vs Ceylon, Blood Sugar Evidence, and How to Use ItCinnamon is more than a warming spice — trials link it to modest blood-sugar effects. Here’s the cassia vs Ceylon difference, the evidence, and the coumarin caveat.
- Ginger: Nausea, Digestion, and Joint Comfort — the EvidenceGinger has some of the strongest spice evidence — especially for nausea, with emerging data for knee osteoarthritis. Here’s what trials report and how it’s used.
- Is Cinnamon Banned in the EU? Coumarin, Cassia vs Ceylon, and Why the US DiffersCinnamon is not banned in the EU — but coumarin, a compound concentrated in cassia cinnamon, is regulated. Here’s the EU vs US picture, cassia vs Ceylon, and what it means for your cup.
Collagen
- Collagen Peptides: What They Are, How They’re Absorbed, and What the Research ShowsCollagen peptides are hydrolyzed collagen broken into short amino-acid chains the body absorbs intact. Here’s the science on bioavailability, skin, joints, and nails — and why hot tea doesn’t “destroy” them.
- Does Collagen Tea Actually Work? An Honest Look at the EvidenceCollagen peptides have real but modest trial support for skin, nails, and joints. Whether collagen tea “works” comes down to dose and consistency. Here’s a straight read of the evidence.
- Does Hot Water Destroy Collagen? The Tea and Coffee Question, AnsweredNo — collagen peptides are already hydrolyzed, so brewing-temperature water dissolves them rather than destroying them. Here’s the science behind adding collagen to hot tea or coffee.
- Is Collagen Tea Safe? A Guide by GroupCollagen peptides are generally well tolerated. For collagen tea, the main safety question is caffeine from the tea base. Here’s what adults, women, pregnant and breastfeeding people, children, and older adults should know.
Functional Botanicals
- Ashwagandha: An Adaptogen for Stress and Sleep — What the Trials ShowAshwagandha is the most-studied adaptogen, with randomized trials reporting reduced stress and improved sleep. Here’s the evidence, the doses used, and the caveats.
- The Best Adaptogen Tea: Ingredients Ranked by the Research"Adaptogen tea" is a category, not a guarantee. Here is what published research actually describes for the main adaptogen ingredients — and why standardized extracts matter more than the label.
- Turmeric and Curcumin: Anti-Inflammatory Evidence and the Bioavailability ProblemCurcumin, turmeric’s active compound, has real anti-inflammatory and osteoarthritis evidence — but is poorly absorbed on its own. Here’s the science and the black-pepper fix.
