HelloPharmacist Scorecard of Red Tea Rooibos Powder by TerraVita Premium Collection

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 10, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product is just one active ingredient: red tea rooibos powder. Rooibos is a naturally caffeine-free herbal tea from South Africa made from the leaves and stems of the rooibos plant.

There are no other active ingredients and no inactive fillers listed.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Rooibos product and its label doesn't state a use — see Rooibos's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The effectiveness of rooibos for any medical condition isn't established in the data we hold. We have ratings for age-related cognitive decline, allergies, anxiety, cancer, heart disease, and diabetes — and for all of them, the evidence is insufficient to rate.

That doesn't mean rooibos doesn't work; it means the research we have isn't strong enough to say one way or another. If you're thinking about using it for a specific health goal, talk it over with your doctor or pharmacist about what the current evidence shows.

The evidence, ingredient by ingredient Rooibos

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Rooibos tea is generally well tolerated when you drink it in normal beverage amounts. That said, there's a caution: concentrated extracts (like powders you mix yourself) haven't been well studied, so use them carefully and check with your provider before regular use.

In one case report, a man who drank 10 cups daily for over a year developed liver problems and a low platelet count. While this is rare, it shows that very large, long-term doses can cause liver damage in some people.

Side effects, ingredient by ingredient Rooibos

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Rooibos.
  • The most serious interaction on file is rated Moderate.
  • For scale: 880 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check these medications before adding rooibos powder to your routine: CYP3A4 substrates (a large class covering heart, cholesterol, and some cancer drugs), ACE inhibitors (blood pressure medications), and CYP2C19, CYP1A2, CYP2D6, and CYP2C9 substrates (which includes many common antidepressants, pain relievers, and antihistamines). All of these interactions are Moderate severity — meaning rooibos could increase how strong your medication becomes.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Rooibos powder is fine as an occasional tea, but if you take any regular medications — especially blood pressure drugs, cholesterol pills, antidepressants, or heart medications — you'll want to check them against this product's interactions before starting. The enzyme-inhibiting effect could make your drugs stronger than intended.

Talk with your own doctor or pharmacist about whether it's safe for you to use regularly.

Red Tea Rooibos Powder by TerraVita Premium Collection: Common Questions

Does Red Tea Rooibos Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Red Tea Rooibos Powder has a known interaction with 879 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Red Tea Rooibos Powder contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is rooibos safe to drink every day?
In normal beverage amounts, rooibos tea is generally well tolerated. But if you're using the powder as a concentrated extract regularly, there isn't much research on that, so talk with your doctor or pharmacist first. One case report described liver damage in someone who drank 10 cups daily for over a year — so very large amounts over a long time can be risky.
Can I take this if I'm on a blood pressure medication?
Not without checking first. Rooibos can inhibit the enzyme that ACE inhibitors (a common blood pressure drug) target, which means your medication could become stronger and potentially lower your blood pressure too much. Show this page to your doctor or pharmacist before starting rooibos.
Does rooibos have caffeine?
No — rooibos is naturally caffeine-free, so it won't give you a caffeine boost or jitters.
What does rooibos actually do for your health?
The evidence we have for rooibos isn't strong enough to rate it for any specific condition — including heart health, diabetes, anxiety, and cognitive decline. You may see claims online, but the research backing them up isn't established in our data.
Can I take this with my cholesterol medication?
Animal research shows that rooibos extract increased atorvastatin (Lipitor) levels six-fold, which is a big increase. If you're on this or other statin drugs, talk with your doctor or pharmacist before using rooibos regularly — don't start it on your own.
