HelloPharmacist Scorecard of Annatto Seed 450 mg 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 Jul 16, 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 contains one active ingredient: annatto, a seed extract traditionally used in cooking and sometimes used medicinally. Each capsule delivers 450 mg of annatto.

The capsule itself is made from gelatin and water, which are inactive ingredients.

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 Annatto product and its label doesn't state a use — see Annatto'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 evidence we have on annatto doesn't support its use for athletic performance, benign prostatic hyperplasia (BPH — an enlarged prostate gland), or exercise-induced muscle soreness. All of these claims carry insufficient evidence.

In other words, we don't yet have reliable data showing it works for these purposes.

The evidence, ingredient by ingredient Annatto

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.

Annatto is generally recognized as safe when used as a food coloring, but supplement doses at the strength in this product haven't been well studied. The safety notes advise caution: food amounts are likely fine, but concentrated supplement doses need approval from your doctor first.

Side effects are uncommon but worth knowing about. Annatto leaf seems well tolerated when taken by mouth, though constipation has been reported rarely.

Allergic reactions to annatto are rare overall but can happen — ranging from hives and facial swelling to severe drops in blood pressure and anaphylaxis (a serious allergic emergency). One case report linked annatto food coloring to worsening of irritable bowel syndrome (IBS) symptoms like diarrhea, bloating, and abdominal pain.

If you have a known allergy to annatto or a history of reactions to annatto-containing foods or cosmetics, don't use this product.

Side effects, ingredient by ingredient Annatto

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 — Annatto.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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.

If you take antidiabetes drugs (medications that lower blood sugar), check with your doctor or pharmacist before starting this product. Annatto may affect your blood sugar unpredictably and could make your medication less effective or raise the risk of low blood sugar.

Monitor your blood glucose levels closely.

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.

Annatto supplement is used traditionally but lacks strong evidence for the conditions listed on supplement labels. Its main concern is a documented interaction with diabetes medications, which could affect blood sugar control.

If you take any diabetes drug, talk with your doctor or pharmacist before starting — they can help you monitor your blood sugar safely. If you have a history of allergic reactions to annatto in food or cosmetics, skip this product.

Annatto Seed 450 mg by TerraVita Premium Collection: Common Questions

Does Annatto Seed 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Annatto Seed 450 mg has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Annatto Seed 450 mg 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.
Can I take annatto if I have diabetes or take diabetes medication?
Not without checking first. Animal studies suggest annatto may affect blood sugar — either lowering it further or raising it — which could interfere with how well your diabetes medication works. Talk with your doctor or pharmacist before you start; they can help you monitor your blood sugar safely if you decide to use it.
Does annatto have any known side effects?
Annatto leaf taken by mouth is generally well tolerated. Constipation has been reported rarely. Allergic reactions are uncommon but can be serious — ranging from hives and swelling to anaphylaxis (a dangerous allergic emergency). One case report linked annatto food coloring to worsening irritable bowel syndrome symptoms.
Is annatto safe to take as a supplement?
Annatto is recognized as safe as a food coloring, but supplement doses at this strength haven't been well studied. The available safety data suggests caution: food amounts are likely fine, but concentrated supplement doses like these should be approved by your doctor first.
Can I take annatto if I'm pregnant or breastfeeding?
We don't have pregnancy and lactation safety data on file for annatto supplements. Because the information isn't established, talk with your doctor or pharmacist for personalized advice before taking it.
Does annatto actually work for athletic performance or muscle soreness?
The evidence we hold doesn't support annatto for athletic performance, prostate health, or exercise-induced muscle soreness — all of these claims carry insufficient evidence. In other words, we don't yet have reliable data showing it works for these purposes.
What if I'm allergic to annatto in food or cosmetics — can I take this supplement?
No. If you've had allergic reactions to annatto-containing foods or cosmetics, don't use this supplement. Allergic reactions to annatto can range from mild (hives) to serious (severe drop in blood pressure or anaphylaxis).
