Rooibos and Diabetes: A Naturally Supportive Choice

Managing diabetes often means paying close attention to daily habits, particularly food and drink. Rooibos tea, a naturally caffeine-free herbal infusion grown only in South Africa, may be a helpful addition to a diabetes-friendly lifestyle.

At Carmién Tea, we’ve worked with rooibos from soil to sip for over two decades. Our teas are organically farmed, Fairtrade certified, and packed at source with full traceability. Rooibos has long been celebrated for its health-supporting properties, and research is beginning to show its potential role in helping manage blood sugar levels.

How Rooibos May Support Blood Sugar Balance

One of rooibos’s most unique compounds is an antioxidant called aspalathin. According to early laboratory studies, aspalathin may help lower high blood sugar levels and improve insulin resistance, both key concerns for people with type 2 diabetes (Dludla et al., 2017). While most of this research has been conducted on animal or cellular models, the findings are promising and support rooibos’s growing reputation as a naturally beneficial beverage.

Importantly, rooibos is naturally sugar-free and contains no caffeine. This makes it an ideal option for regular consumption, especially when managing energy levels and avoiding blood sugar spikes (WebMD, 2022). Unlike sweetened beverages or caffeinated teas, rooibos offers hydration and flavour without added stress to the system.

When to Drink Rooibos

  • Rooibos is gentle and versatile enough to be enjoyed throughout the day. Here are some common moments to include in your routine:
  • Morning: Start the day with a warm cup of rooibos. Its smooth, earthy flavour provides comfort without the stimulation of caffeine, helping you ease into the day calmly.
  • After meals: Drinking rooibos after eating may support digestion and help reduce oxidative stress caused by post-meal blood glucose fluctuations (Dludla et al., 2017).
  • Afternoon break: Rooibos is a helpful alternative to sugary or caffeinated drinks during the afternoon slump. Its natural sweetness makes it a satisfying option without needing sugar.
  • Before bed: Because it contains no caffeine, rooibos is safe to drink in the evening. It can help you wind down without interfering with sleep.
  • Hot days: Rooibos also makes an excellent cold brew. Steep it for 20 – 30 minutes and let it cool to enjoy it as a refreshing, sugar-free iced tea. It’s a practical and hydrating alternative to sugary soft drinks, especially for those watching their glucose levels.

May Support Heart and Metabolic Health

Beyond blood sugar, rooibos may also benefit heart health. Studies suggest it may help lower LDL (bad) cholesterol, increase HDL (good) cholesterol, and improve overall blood vessel function (Healthline, 2023; Medical News Today, 2022). These are particularly important for people with diabetes, who face a higher risk of cardiovascular complications.

A Simple, Sustainable Option

Rooibos is not a treatment for diabetes, but it may offer daily support as part of a balanced lifestyle. It’s easy to prepare, well tolerated, and backed by decades of traditional use. In fact, studies have found no known side effects from drinking rooibos, even over the long term (Snijman et al., 2005).

At Carmién, we grow and pack our rooibos in the Cederberg mountains, ensuring quality and care in every box. Our range includes pure rooibos and functional blends, all caffeine-free and sustainably packaged. Whether enjoyed warm or chilled, rooibos is a naturally supportive choice for your wellness routine.
