HelloPharmacist Scorecard of Apple 450 mg 4:1 Extract 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
This product contains one active ingredient: apple extract, a 4:1 concentrate of apple fruit supplying 450 mg per capsule. The capsules themselves are made with gelatin and water as inactive ingredients.
Does it work?
Couldn't assess
The evidence for apple extract isn't established in the data we hold. We have effectiveness ratings for several uses — Alzheimer disease, cancer, dental plaque, diabetes, and diarrhea — but all are marked as having insufficient reliable evidence.
That means the research so far doesn't support a clear claim for any of these conditions.
How safe is it?
Well-documented data
Whole apples are well tolerated and safe when eaten in normal amounts. The most common side effects from apple products are bloating and flatulence.
Rarely, people allergic to other fruits in the Rosaceae family — apricot, almond, plum, peach, pear, and strawberry — can also be allergic to apples, occasionally resulting in a serious allergic reaction called anaphylaxis. Apple seeds contain cyanide and can cause serious harm if ingested in large amounts.
For pregnancy and breastfeeding, there isn't enough data on concentrated apple extracts to know either way — whole apples as food are considered safe in both, but supplements haven't been well studied. Talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding.
Meds to double-check
Major interaction found
Before taking this product, double-check with your pharmacist if you take OATP substrate drugs (a large class including fexofenadine, atenolol, and aliskiren), blood pressure medications, diabetes medications, or lithium. Apple extract can significantly lower the blood levels of several of these, which may reduce their effectiveness.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This product is a single-ingredient apple extract with no proven effectiveness for the conditions listed in our data. If you take any blood pressure medications, heart medications, diabetes medications, or lithium, don't start this without checking your exact drugs first — the interactions are significant and can reduce how well your medications work.
A quick conversation with your pharmacist will tell you whether it's right for you.

Apple 450 mg 4:1 Extract by TerraVita Premium Collection Drug Interactions
HelloPharmacist Interaction Report
Apple 450 mg 4:1 Extract by TerraVita Premium Collection has documented interactions with a significant number of medications.
The most serious concern is with a large drug class called OATP substrates — medications that rely on a specific transport system in your intestines to be absorbed. Apple extract can block that transport, cutting their blood levels by up to 78%, which may make them less effective.
Common OATP substrates include fexofenadine (Allegra, an allergy medication), atenolol (Tenormin, a heart and blood pressure drug), and aliskiren (Tekturna, a blood pressure medication).
Read the full breakdown — every affected drug type, severity by severity
Apple extract may also interfere with blood pressure control if you take antihypertensive drugs (blood pressure medications), and it could raise your blood glucose, which may affect how well diabetes medications work. There's also a case report of apple juice decreasing lithium levels — important if you take lithium for mood disorders, since low levels can be unsafe.
Altogether, these interactions span 297 individual medications. Even if you don't recognize a drug name, the categories above cover many common prescriptions.

For each ingredient in Apple 450 mg 4:1 Extract with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Apple Extract
Organic Anion-Transporting Polypeptide Substrates (Oatp)
Concomitant consumption of apple juice can significantly decrease oral absorption and blood levels of OATP substrates.
Research shows that consuming apple juice inhibits OATP, which reduces bioavailability of oral drugs that are substrates of OATP. Fexofenadine, atenolol, and aliskiren are substrates of OATP. Clinical research shows that coadministration of apple juice decreases bioavailability of fexofenadine by up to 78%, aliskiren by 63%, and atenolol by up to 82%. These effects appear to increase with larger quantities of apple juice. It is thought that apple juice might affect OATP for only a short time. Therefore, separating drug administration and consumption of apple juice by at least 4 hours might avoid this interaction.
Aliskiren (Tekturna, Rasilez)
Concomitant consumption of apple juice can significantly decrease oral absorption and blood levels of aliskiren.
Pharmacokinetic research shows that coadministration of apple juice 200 mL along with aliskiren 150 mg decreases the bioavailability of aliskiren by 63%. Apple juice seems to inhibit organic anion transporting polypeptide (OATP), which is involved in drug uptake in the gut, liver, and kidney. It is thought that apple juice might affect OATP for only a short time. Therefore, separating drug administration and consumption of apple juice by at least 4 hours might avoid this interaction.
Antidiabetes Drugs
Theoretically, consuming apple juice with antidiabetes drugs might interfere with blood glucose control.
Clinical research suggests that consuming apples or drinking apple juice can raise blood glucose levels, with the effects of drinking apple juice being more significant than consuming apples.
Antihypertensive Drugs
Consuming apple juice with antihypertensive drugs might interfere with blood pressure control.
Some clinical evidence suggests that consuming apple and cherry juice can increase blood pressure in elderly patients.
Atenolol (Tenormin)
Concomitant consumption of apple juice can significantly decrease oral absorption and blood levels of atenolol.
Pharmacokinetic research shows that coadministration of apple juice 600-1200 mL decreases levels of atenolol by 58% to 82% in a dose-dependent manner. Apple juice seems to inhibit organic anion transporting polypeptide (OATP), which is involved in drug uptake in the gut, liver, and kidney. It is thought that apple juice might affect OATP for only a short time. Therefore, separating drug administration and consumption of apple juice by at least 4 hours might avoid this interaction.
Fexofenadine (Allegra)
Concomitant consumption of apple juice can significantly decrease oral absorption and blood levels of fexofenadine.
Pharmacokinetic research shows that coadministration of apple juice 400-1200 mL along with fexofenadine 60-120 mg decreases bioavailability of fexofenadine by up to 78%. Coadministration with smaller quantities of apple juice (150 mL or less) does not appear to affect the bioavailability of fexofenadine. Apple juice seems to inhibit organic anion transporting polypeptide (OATP), which is involved in drug uptake in the gut, liver, and kidney. It is thought that apple juice might affect OATP for only a short time. Therefore, separating drug administration and consumption of apple juice by at least 4 hours might avoid this interaction.
Lithium
There is some concern that concomitant consumption of apple juice might decrease oral absorption and blood levels of lithium.
In one case report, a patient had an undetectable serum lithium level when lithium citrate was administered with apple juice. When lithium was administered with an alternative beverage, the lithium level became detectable and the patient demonstrated clinical improvement.
