Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Blood Pressure Health contains 2 active ingredients. Olive leaf extract (from Olea europaea) is included for its traditional use in supporting cardiovascular health.

French Grape seed extract (from Vitis vinifera) is added for similar purposes, particularly for its potential effects on circulation and venous function. The product also contains inactive ingredients—hydroxypropyl methylcellulose, acacia gum, microcrystalline cellulose, silica, and vegetable source magnesium stearate—which are standard capsule fillers and binders that help hold the supplement together.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: support healthy blood pressure and circulation.
  • We looked for evidence on: Hypertension, Cardiovascular disease (CVD), Atherosclerosis, Hypercholesterolemia, Chronic venous insufficiency (CVI), Endothelial function — and 2 related terms.
  • The strongest evidence on file: Grape is rated "Possibly Effective" for Chronic venous insufficiency (CVI) (Natural Medicines).
  • Also on file: Grape is rated "Insufficient Reliable Evidence To Rate" for Atherosclerosis, Cardiovascular disease (CVD), Hypercholesterolemia, Hypertension.

The evidence for what these ingredients can do is limited. Grape seed extract is possibly effective for chronic venous insufficiency (that heavy, achy feeling in your legs from poor circulation), but the evidence for it reducing nausea from chemotherapy, improving hay fever, or supporting weight loss is weak—these are rated possibly ineffective.

Olive leaf extract doesn't have established evidence in our data for any of the conditions it's been studied for, including bone health, osteoarthritis, shingles, and cold prevention. The research just isn't strong enough yet to say it works for these purposes.

The evidence, ingredient by ingredient Olive Grape

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Grape seed extract is generally well tolerated in clinical studies. The most common side effects are mild—abdominal pain, diarrhea, dry mouth, stomach upset, headache, joint pain, and nausea.

A rare serious reaction (anaphylaxis to grape skin) has been reported. Some people using specific grape leaf extracts have reported sore throat and cough, though these occurred at rates similar to placebo.

Olive leaf extract also seems well tolerated when used as food and in supplements. Headache and stomach discomfort are the most reported side effects.

One person in a trial reported acne. Because concentrated olive supplements are less studied than the food form, the safety data aren't as complete.

For pregnancy, there isn't enough data on concentrated grape supplements to know if they're safe—avoid them and talk with your doctor. There's also not enough information on grape supplements while breastfeeding.

Olive leaf extract pregnancy and breastfeeding safety data isn't on file.

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 2 matched ingredients can interact with medications — Grape.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs.
  • For scale: 911 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 with your pharmacist if you take blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel, others)—there's a Moderate risk of increased bleeding. Also check if you take medications metabolized by CYP2D6, CYP2E1, or CYP3A4 enzymes, or if you take cyclosporine (an immunosuppressant) or midazolam (a sedative)—grape seed extract may change how these drugs work.

If you're on cyclosporine, space it at least 2 hours away from this supplement.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you have poor circulation or are looking to support cardiovascular health and don't take blood thinners or certain other medications, this might be worth trying—especially the grape seed part, which has some evidence for chronic venous insufficiency. But check your medications first, because grape seed extract affects many drugs.

Olive leaf extract's effectiveness isn't well established yet. Talk to your pharmacist before you start, especially if you're on any prescription medications.

French Grape (Vitis vinifera) seed extract9 drug types · 910 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, grape extracts may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that grape extracts might decrease platelet aggregation.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Ingesting grape juice with cyclosporine can reduce cyclosporine absorption.
A small pharmacokinetic study in healthy young adults shows that intake of purple grape juice 200 mL along with cyclosporine can decrease the absorption of cyclosporine by up to 30% when compared with water. Separate doses of grape juice and cyclosporine by at least 2 hours to avoid this interaction.

Likelihood Possible Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, grape juice might reduce the levels of CYP1A2 substrates.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of CYP1A2.

Likelihood Possible Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, grape seed extract may increase the levels of CYP2D6 substrates.
In vitro evidence suggests that grape seed extract might inhibit CYP2D6 enzymes. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, grape seed extract might increase the levels of CYP2E1 substrates.
In vitro and animal research suggests that grape seed proanthocyanidin extract inhibits CYP2E1 enzymes. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

It is unclear if grape seed extract inhibits or induces CYP3A4; research is conflicting.
In vitro evidence suggests that grape seed extract might inhibit CYP3A4 enzymes. However, evidence from animal research shows that grape seed extract may induce CYP3A4 in the liver. So far, these interactions have not been reported in humans.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, long-term intake of grape seed extract might decrease the effects of midazolam.
Animal research shows that subchronic ingestions of grape seed extract can increase the elimination of intravenous midazolam by increasing hepatic CYP3A4 activity. Single doses of grape seed extract do not appear to affect midazolam elimination.

Likelihood Possible Evidence D
Phenacetin

Grape juice might decrease phenacetin absorption.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of cytochrome P450 1A2 (CYP1A2).

Likelihood Possible Evidence B
Cytochrome P450 2C9 (Cyp2C9) Substrates

It is unclear if grape juice or grape seed extract inhibits CYP2C9; research is conflicting.
In vitro evidence shows that grape seed extract or grape juice might inhibit CYP2C9 enzymes. However, a small pharmacokinetic study in healthy adults shows that drinking 8 ounces of grape juice once does not affect the clearance of flurbiprofen, a probe-drug for CYP2C9 metabolism. The effects of continued grape juice consumption are unclear.

Blood Pressure Health by Terry Naturally: Common Questions

Does Blood Pressure Health by Terry Naturally interact with any medications?
Yes. Based on its ingredients, Blood Pressure Health has a known interaction with 910 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Blood Pressure Health contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
What is olive leaf extract supposed to do?
Olive leaf extract is traditionally used to support heart health and circulation, but we don't have strong scientific evidence that it works for osteoarthritis, bone health, shingles, or infection prevention. The research just isn't established yet.
What about the grape seed extract—what's it for?
Grape seed extract has some evidence showing it may help with chronic venous insufficiency, that heavy or achy feeling in your legs from poor circulation. It's less likely to help with nausea from chemotherapy, hay fever, or weight loss.
Are there side effects I should know about?
Most side effects are mild—headache, stomach upset, diarrhea, dry mouth, joint pain. Olive leaf may cause acne in rare cases. Very rarely, grape can trigger an allergic reaction (anaphylaxis). Let your pharmacist know if you experience anything unusual.
Is it safe to take during pregnancy?
There isn't enough safety data on concentrated grape supplements during pregnancy, so it's best to avoid them and talk with your doctor. We don't have safety information on file for olive leaf extract in pregnancy either—your doctor or pharmacist can give you personalized advice.
Can I take this if I'm breastfeeding?
There's not enough information on concentrated grape supplements while breastfeeding, so check with your doctor first. We don't have breastfeeding safety data for olive leaf extract, so mention both ingredients to your pharmacist.
How does grape seed interact with so many medications?
Grape seed extract affects the liver enzymes (called cytochrome P450) that break down many common medications—blood thinners, sedatives, immunosuppressants, and others. Depending on which enzyme it affects, it can either increase or decrease drug levels in your bloodstream, which changes how well the medication works.
