HelloPharmacist Scorecard of Rice Protein 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.

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: rice protein at 450 mg per capsule. Rice protein is derived from rice grains and used as a plant-based protein source.

The capsule also contains gelatin and water as inactive ingredients.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Rice Protein's overall clinical evidence instead.

Moderate

Some clinical evidence supports Rice Protein for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Food allergies — rated "Possibly Effective" (Natural Medicines).

Rice protein has possibly effective evidence for helping with food allergies — though this is an unusual use for a protein supplement and would depend on your specific situation. For exercise-induced muscle soreness and muscle strength, the evidence we hold isn't reliable enough to say whether it works.

If you're considering it for one of those reasons, that's a conversation to have with your doctor or a sports nutritionist.

The evidence, ingredient by ingredient Rice Protein

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.

Rice protein is generally well tolerated when taken by mouth in healthy adults. In rare cases, especially in infants and young children, it's been reported to cause enterocolitis — inflammation of the small intestine with symptoms like vomiting, diarrhea, and dehydration.

Although rice protein is considered hypoallergenic, allergies to rice proteins have been reported, both from topical use and when taken by mouth. For pregnancy and breastfeeding, the data on concentrated rice protein supplements is limited.

Whole food rice is fine, but concentrated supplements haven't been well studied in these situations. Talk with your doctor or pharmacist before taking this during pregnancy or while breastfeeding to decide what's right for you.

Why this rating?

Ace Inhibitors (Aceis)

In laboratory research, hydrolyzed rice protein inhibits angiotensin-converting enzyme (ACE). In animal research, the inhibition of ACE is correlated with a reduction in systolic blood pressure. So far, this effect has not been shown in humans. Theoretically, concomitant use of rice protein and ACE inhibitors may increase the risk of blood pressure becoming too low. Use with caution. ACE inhibitors include benazepril (Lotensin), captopril (Capoten), enalapril (Vasotec), fosinopril (Monopril), lisinopril (Prinivil, Zestril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), and trandolapril (Mavik).

Rice Protein 450 mg by TerraVita Premium Collection: Common Questions

Does Rice Protein 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Rice Protein 450 mg has a known interaction with 23 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Rice Protein 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 this if I'm pregnant?
Concentrated rice protein supplements haven't been well studied in pregnancy. Whole rice as a food is fine, but for a supplement, talk with your doctor or pharmacist first — they can give you personalized advice based on your situation.
Is rice protein safe for kids?
Rice protein is generally well tolerated, but in rare cases — especially in infants and young children — it's been reported to cause enterocolitis (intestinal inflammation with vomiting and diarrhea). If your child has digestive issues or a history of food allergies, mention it to your pediatrician before giving them this supplement.
Can I be allergic to rice protein?
Yes. Although rice protein is considered hypoallergenic, allergies to rice proteins have been reported. If you've had rice allergies before or notice symptoms like digestive upset after taking this, stop and talk with your doctor.
Does this actually help with muscle soreness?
The evidence we hold isn't reliable enough to say whether rice protein helps with exercise-induced muscle soreness. If that's your goal, ask your doctor or a sports nutritionist — they may have other options to discuss.
Can I take this while breastfeeding?
Concentrated protein supplements like this one haven't been well studied during breastfeeding. Whole rice as food is likely fine, but check with your doctor or pharmacist first to make sure it's right for you.
