Rooibos tea, also known as redbush tea, is a caffeine-free herbal tea that has grown in popularity in recent years due to its potential health benefits and lack of caffeine. For many, it's a great choice because of it's taste and nutrition.
However, like with anything you consume, it's important to know the positives and the draw backs. We'll look at whether rooibos is truly caffeine-free and explore the different things you might want to know before making it a regular part of what you drink.
Is Rooibos Tea Completely Caffeine-Free?
Yes, rooibos tea is naturally caffeine-free, making it a good choice for those looking to reduce or eliminate caffeine from their diet. Rooibos comes from the leaves of the Aspalathus linearis plant which contains no caffeine. Unlike traditional teas like black tea, green tea, and white tea that derive from the Camellia sinensis plant and contain varying amounts of caffeine, rooibos does not.
Benefits of Drinking Rooibos Tea
Helps You Sleep Better
The caffeine in drinks like coffee and traditional teas can make it harder to fall asleep and reduce sleep quality by interrupting the body's circadian rhythms. Rooibos is naturally caffeine-free, so it avoids any caffeine-related sleep disruption. This makes rooibos a good choice to drink in the evenings when you want to wind down for bedtime.
Reduces Stress, Anxiety, and Headaches
Caffeine stimulates the release of cortisol and epinephrine, hormones associated with the "fight or flight" stress response. Too much caffeine can overstimulate this response, leading to jitteriness, anxiety and tension headaches. Switching to the caffeine-free alternative of rooibos tea can help calm this stress response, easing anxiety symptoms and preventing caffeine-triggered headaches.
Good for Hydration
Staying properly hydrated is essential for all aspects of health, but drinking plain water constantly can be boring. The herbal infusion of rooibos adds flavor and variety while still hydrating the body effectively like water, as it is 98% water. Rooibos provides hydration plus therapeutic plant compounds not found in plain water.
Rich in Antioxidants
Antioxidants like aspalathin and quercetin in rooibos tea help prevent cell damage from free radicals, which are unstable molecules linked to chronic disease, inflammation and aging. These antioxidants support the body's natural defenses and may lower oxidative stress which plays a role in heart disease, cancer progression, liver disease, diabetes and neurodegenerative diseases.
Improves Heart Health
The antioxidant effects of rooibos protect LDL cholesterol from becoming oxidized. When LDL cholesterol becomes oxidized it is more likely to stick to artery walls and form plaque, raising heart disease risk. Rooibos may help prevent this oxidation and inhibit the progression of atherosclerosis.
Aids Digestion
Compounds in rooibos serve as antispasmodics, helping to reduce spasms, cramps and discomfort in the gastrointestinal tract. By soothing intestinal muscles and easing inflammation, rooibos shows potential to relieve constipation, cramping, nausea and other digestion issues in preliminary studies.
Considerations and Side Effects of Drinking Rooibos Tea
Blood Pressure Effects
Those with hypotension or low blood pressure may want to exercise some caution with rooibos. Limited evidence indicates rooibos may lower blood pressure which could exacerbate hypotension symptoms like dizziness or fainting.
Contains Trace Amounts of Aluminum
The aluminum content of rooibos is concerning for some consumers. However, the aluminum in rooibos occurs naturally and studies show the body absorbs very little aluminum from tea. But those with kidney disease may want to limit intake.
Rare Allergic Reactions
There have been a handful of reported cases of allergic reaction to rooibos involving hives, difficulty breathing, and other symptoms. Allergies appear to be rare but those with plant or food allergies should use caution when first trying rooibos tea.
Can Stain Teeth Over Time
Like coffee, soy sauce, beet juice and other dark liquids, rooibos contains pigments that can stain teeth over time with heavy use. Proper dental hygiene and brushing helps prevent staining.
How Much Rooibos Tea Should You Drink Per Day?
Rooibos tea is likely safe to consume in normal amounts but there is no official guideline for daily intake. Caffeine-free herbal teas like rooibos do not cause the same issues as overconsuming caffeinated beverages.
However, there are many recommendations to follow. Since rooibos is high in antioxidants, it’s best to start with 1-2 cups per day to assess tolerance. Most healthy adults can safely consume up to 4 to 6 eight ounce cups of rooibos tea per day. This provides sufficient antioxidant intake without exceeding advised aluminum limits. Those with medical conditions should follow the advice of their doctor.
Drinking more than 10 eight ounce cups of rooibos tea could result in aluminum consumption exceeding the Tolerable Daily Intake (TDI). Too much aluminum from any source is unhealthy over the long-term Drinking 1-4 cups per day seems reasonable for most healthy people to take advantage of the potential benefits of rooibos while limiting risk.
