Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Cardio Care contains 4 active ingredients. Vitamin B3 (niacin) is a B vitamin that plays a role in energy metabolism and has been studied for cholesterol and cardiovascular support.

Hawthorn extract comes from the berries and leaves of the hawthorn plant and has a long history in heart health formulations. Pine bark extract, also called maritime pine, is a source of compounds called proanthocyanidins.

Motherwort extract is derived from the motherwort plant and has been used traditionally for heart and circulation support. The capsules also contain cellulose as an inactive ingredient.

Evidence for Intended Use · database check

Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: heart and cardiovascular health support.
  • We looked for evidence on: Angina, Arrhythmia, Atherosclerosis, Cardiovascular disease (CVD), Congestive heart failure (CHF), Heart failure — and 4 related terms.
  • The closest evidence on file: Maritime Pine is rated "Possibly Ineffective" for Hyperlipidemia (Natural Medicines).
  • Also on file: Niacin is rated "Ineffective" for Cardiovascular disease (CVD).
  • Also on file: Motherwort is rated "Insufficient Reliable Evidence To Rate" for Arrhythmia, Heart failure, Hypertension.

The evidence for these ingredients is mixed and depends on what you're taking the product for. Vitamin B3 is likely effective for pellagra (a B3 deficiency disease) and possibly effective for HIV-related cholesterol problems and metabolic syndrome.

Hawthorn extract shows insufficient reliable evidence for angina, anxiety, heart rhythm issues, atherosclerosis, heart disease, or cognitive function—meaning we don't yet have solid data to know if it works for these. Pine bark extract is possibly effective for osteoarthritis and chronic venous insufficiency (poor circulation in the legs) but possibly ineffective for high cholesterol.

Motherwort extract is possibly effective for bleeding but shows insufficient evidence for the other conditions we hold data on. Overall, if you're considering this product for a specific heart or circulation concern, talk with your doctor or pharmacist about whether the evidence supports its use for your situation.

The evidence, ingredient by ingredient Niacin Hawthorn Maritime Pine Motherwort

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin B3 from food and normal supplements is well tolerated, but high-dose niacin—the kind in cardiovascular formulas—commonly causes flushing (up to 70% of users), stomach upset, and elevated liver enzymes. Rare serious effects include liver damage, muscle problems, and vision changes.

High-dose niacin should be avoided in pregnancy unless prescribed; normal amounts in food and prenatal vitamins are fine. Hawthorn extract is generally well tolerated in studies, but because it affects the heart, medical supervision is important if you have a heart condition.

It's not recommended in pregnancy or while breastfeeding due to insufficient safety data. Pine bark extract is generally well tolerated; common side effects include stomach upset, dizziness, and vertigo.

It's possibly safe in pregnancy but best avoided while breastfeeding. Motherwort extract is generally tolerated short-term by healthy adults but may cause diarrhea or stomach irritation, and can trigger contact dermatitis or sun sensitivity if it touches your skin.

It's considered likely unsafe in pregnancy because it may stimulate the uterus, and there isn't enough safety data for breastfeeding.

Vitamin B315 drug types · 729 drugs

Alcohol (Ethanol)

Concomitant use of alcohol and niacin might increase the risk of flushing and hepatotoxicity.
Alcohol can exacerbate the flushing and pruritus associated with niacin. Large doses of niacin might also exacerbate liver dysfunction associated with chronic alcohol use. A case report describes delirium and lactic acidosis in a patient taking niacin 3 grams daily who ingested 1 liter of wine. Advise patients to avoid large amounts of alcohol while taking niacin.

Likelihood Probable Evidence D
Allopurinol (Zyloprim)

Theoretically, niacin might antagonize the therapeutic effects of uricosurics such as allopurinol.
Large doses of niacin can reduce urinary excretion of uric acid, potentially resulting in hyperuricemia. Doses of uricosurics such as allopurinol might need to be increased to maintain control of gout in patients who start taking niacin. People who have frequent attacks of gout despite uricosuric therapy should avoid niacin.

Likelihood Probable Evidence C
Anticoagulant/Antiplatelet Drugs

Theoretically, niacin may have additive effects when used with anticoagulant or antiplatelet drugs.
Several cases of clotting factor synthesis deficiency and coagulopathy have been reported in patients taking sustained-release niacin. Also, thrombocytopenia has been reported in patients treated with niacin or niacin plus lovastatin.

Likelihood Possible Evidence D
Antidiabetes Drugs

Niacin can increase blood glucose levels and may diminish the effects of antidiabetes drugs.
Niacin impairs glucose tolerance in a dose-dependent manner, probably by causing or aggravating insulin resistance and increasing hepatic production of glucose. In diabetes patients, niacin 4.5 grams daily for 5 weeks can increase plasma glucose by an average of 16% and glycated hemoglobin (HbA1c) by 21%. However, lower doses of 1.5 grams daily or less appear to have minimal effects on blood glucose. In some patients, glucose levels increase when niacin is started, but then return to baseline when a stable dose is reached. Up to 35% of patients with diabetes may need adjustments in hypoglycemic therapy when niacin is added.

Likelihood Probable Evidence B
Antihypertensive Drugs

Theoretically, niacin may increase the risk of hypotension when used with antihypertensive drugs.
The vasodilating effects of niacin can cause hypotension. Furthermore, some clinical evidence suggests that a one-hour infusion of niacin can reduce systolic, diastolic, and mean blood pressure in hypertensive patients. This effect is not observed in normotensive patients.

Likelihood Possible Evidence B
Bile Acid Sequestrants

Bile acid sequestrants can bind niacin and decrease absorption. Separate administration by 4-6 hours to avoid an interaction.
In vitro studies show that colestipol (Colestid) binds about 98% of available niacin and cholestyramine (Questran) binds 10% to 30%.

Likelihood Possible Evidence D
Gemfibrozil (Lopid)

Theoretically, concomitant use of niacin and gemfibrozil might increase the risk of myopathy in some patients.
A case of myopathy from concomitant use of niacin and gemfibrozil has been reported. Niacin alone has also been associated with cases of myopathy. Using gemfibrozil with niacin might further increase the risk of developing myopathy.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use of niacin and hepatotoxic drugs might increase the risk of hepatotoxicity.
Niacin has been associated with cases of liver toxicity, especially when used in pharmacologic doses. Sustained-release niacin preparations appear to be associated with a higher risk of hepatotoxicity than immediate-release niacin.

Likelihood Possible Evidence D
Hmg-Coa Reductase Inhibitors ("Statins")

Theoretically, concomitant use of niacin and statins might increase the risk of myopathy and rhabdomyolysis in some patients.
Some case reports have raised concerns that niacin might increase the risk of myopathy and rhabdomyolysis when combined with statins. However, a significantly increased risk of myopathy has not been demonstrated in clinical trials, including those using an FDA-approved combination of lovastatin and niacin (Advicor).

Likelihood Possible Evidence D
Probenecid (Benemid)

Theoretically, niacin might antagonize the therapeutic effects of uricosurics such as probenecid.
Large doses of niacin reduce urinary excretion of uric acid, potentially causing hyperuricemia. Doses of uricosurics such as probenecid might need to be increased to maintain control of gout in patients who start taking niacin. People who have frequent attacks of gout despite uricosuric therapy should avoid niacin.

Likelihood Probable Evidence C
Sulfinpyrazone (Anturane)

Theoretically, niacin might antagonize the therapeutic effects of uricosurics such as sulfinpyrazone.
Large doses of niacin reduce urinary excretion of uric acid, potentially causing hyperuricemia. Doses of uricosurics such as sulfinpyrazone might need to be increased to maintain control of gout in patients who start taking niacin. People who have frequent attacks of gout despite uricosuric therapy should avoid niacin.

Likelihood Probable Evidence C
Thyroid Hormone

Theoretically, niacin might antagonize the therapeutic effects of thyroid hormones.
Clinical research and case reports suggests that taking niacin can reduce serum levels of thyroxine-binding globulin by up to 25% and moderately reduce levels of thyroxine (T4). Patients taking thyroid hormone for hypothyroidism might need dose adjustments when using niacin.

Likelihood Probable Evidence D
Transdermal Nicotine (Nicoderm)

Theoretically, concomitant use of niacin and transdermal nicotine might increase the risk of flushing and dizziness.
Niacin and nicotine can both cause flushing and dizziness.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is limited evidence that niacin may increase the anticoagulant effects of warfarin.
In a case report, a patient on warfarin developed an elevated international normalized ratio (INR) of 3.9 after taking niacin for two weeks. The patient's INR was previously stable, ranging between 2 and 3 in recent months, and no other medication changes were identified. The elevated INR returned to therapeutic range within 4 days following the discontinuation of niacin.

Likelihood Possible Evidence D
Aspirin

Large doses of aspirin might alter the clearance of niacin.
Aspirin is often used with niacin to reduce niacin-induced flushing. Doses of 80-975 mg aspirin have been used, but 325 mg appears to be optimal. Aspirin also seems to reduce the clearance of niacin by competing for glycine conjugation. Taking aspirin 1 gram seems to reduce niacin clearance by 45%. This is probably a dose-related effect and not clinically significant with the more common aspirin dose of 325 mg.

Likelihood Likely Evidence B
Vitamin B3 full monograph & interactions

Pine Bark Extract3 drug types · 327 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, maritime pine bark extract might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Clinical research suggests that maritime pine bark extract inhibits platelet aggregation. However, the clinical significance of this effect is unclear.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, maritime pine bark extract might increase the risk of hypoglycemia when used with antidiabetes drugs.
One clinical study shows that maritime pine bark extract decreases blood sugar in patients with diabetes being treated with antidiabetes agents. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence B
Immunosuppressants

Theoretically, maritime pine bark extract might decrease the effectiveness of immunosuppressant therapy.
In vitro and animal research suggests that maritime pine bark extract has immunostimulant activity. This effect has not been reported in humans.

Hawthorn Extract6 drug types · 191 drugs

Nitrates

Theoretically, concomitant use might cause additive coronary vasodilatory effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.

Likelihood Probable Evidence D
Phosphodiesterase-5 Inhibitors

Theoretically, concomitant use might result in additive vasodilation and hypotension.
Hawthorn might inhibit PDE-5 and cause vasodilation.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research shows that hawthorn can inhibit platelet aggregation. However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract. However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans.

Likelihood Possible Evidence D
Beta-Blockers

Theoretically, concomitant use might cause additive effects on blood pressure and heart rate.
Some evidence shows that hawthorn might lower blood pressure and heart rate.

Likelihood Possible Evidence D
Calcium Channel Blockers

Theoretically, concomitant use might cause additive coronary vasodilation and hypotensive effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, hawthorn might potentiate the effects and adverse effects of digoxin.
Hawthorn appears to improve cardiac output; however, hawthorn does not appear to affect digoxin pharmacokinetics. Case reports suggest that at least one species of hawthorn root extract (Crataegus mexicana) may produce adverse effects similar to digoxin and can cross-react with digoxin assays, leading to falsely elevated plasma digoxin levels.

Cardio Care by Herbs SRA: Common Questions

Does Cardio Care by Herbs SRA interact with any medications?
Yes. Based on its ingredients, Cardio Care has a known interaction with 1,030 medications, including 14 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cardio Care contains 4 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.
Can I take this if I'm pregnant or breastfeeding?
The safety data advises against motherwort in pregnancy because it may stimulate the uterus. Hawthorn and pine bark lack enough safety information, so they're best avoided during pregnancy and lactation unless your doctor directs otherwise. Vitamin B3 is fine at normal food and prenatal vitamin amounts, but high-dose supplements should be avoided. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy or breastfeeding.
What's the most common side effect I might experience?
Flushing—a warm, red feeling in the face and neck—is the most common side effect, occurring in up to 70% of people taking higher doses of vitamin B3. You may also experience stomach upset, including nausea, heartburn, or diarrhea. These effects often improve within a couple of weeks and may be reduced by taking the product with food.
Is this safe if I have heart disease or high blood pressure?
Because this product contains ingredients that affect blood pressure and heart function, anyone with a heart condition or on heart medications needs medical supervision. Don't start this product without discussing it with your doctor or pharmacist first, especially if you take nitrates, blood pressure drugs, or other cardiac medications.
Can I take this with my blood thinner?
Multiple ingredients in this product—vitamin B3, hawthorn, and pine bark—may increase bleeding risk when combined with blood thinners or antiplatelet drugs. Check with your doctor or pharmacist before combining them; your dosing may need adjustment or monitoring.
Will this raise my blood sugar?
Vitamin B3 can raise blood glucose levels, and pine bark extract may lower it. If you take diabetes medication, the mixed effects mean you should monitor your blood sugar closely and talk with your doctor or pharmacist before starting this product.
What does each ingredient actually do?
Vitamin B3 is a B vitamin involved in energy metabolism and has been studied for cholesterol support. Hawthorn extract and motherwort extract are traditional botanicals used in heart formulas. Pine bark extract is a source of compounds called proanthocyanidins and has been studied for circulation and joint support. None of these has strong evidence for treating specific heart conditions, so discuss your goals with your doctor or pharmacist.
