10 Best Heart Health Supplements
Heart and circulation supplements range from well-labeled single ingredients to formulas with drug-like claims. Some of them, such as red yeast rice and nattokinase, interact with common heart medications, so a precise label matters for safety as well as value.
We ranked hawthorn, nattokinase, plant sterols, red yeast rice, arjuna and other heart and circulation formulas sold on iHerb by label quality. Fish oil and CoQ10 have their own rankings.

Top 10 ranked
#ProductScoreFormServingsPrice
How we ranked them
Every product is scored 0–100 from its label data in the NIH Dietary Supplement Label Database: dosage transparency (35 points - are amounts stated per ingredient, or hidden in a proprietary blend?), label completeness (25), formulation cleanliness (25 - fillers, dyes, titanium dioxide and other non-active ingredients) and ingredient profile (15). The Top 10 admits only products scoring 60 or higher; among those, products with a verified retail listing are shown first so the list is one you can act on. No brand can pay to be included or moved up.
Forms and dosage
- Plant sterols and stanols
- Studied at about 2 g a day; one of the better-evidenced ingredients in this group.
- Nattokinase
- An enzyme measured in fibrinolytic units (FU). It may increase bleeding risk with blood thinners.
- Red yeast rice
- Can contain monacolin K, chemically identical to the statin lovastatin. The FDA treats products with significant amounts as unapproved drugs.
- Herbal extracts (hawthorn, arjuna, garlic)
- Should state extract amount and standardization.
How much to take
Plant sterols around 2 g per day; nattokinase is labeled in FU, commonly 2,000 FU per serving. Herbal doses are product-specific. Anyone on blood pressure, cholesterol or blood-thinning medication should check with a clinician first.
Who it's for
Adults with a specific, clearly labeled ingredient in mind and a clinician aware of what they take.
What to watch out for
Red yeast rice without a stated monacolin content, nattokinase or garlic with anticoagulants, and blends that make blood-pressure claims without disclosing amounts.

80Frequently Asked Questions
Is red yeast rice the same as a statin?
It can contain monacolin K, which is chemically the same as lovastatin, in varying amounts. That is why it should not be combined with statins without medical advice.
Why are fish oil and CoQ10 not here?
They have their own rankings. This one covers other heart and circulation products.
How are heart health supplements ranked?
Products are ranked by SupplementScore, which evaluates label quality across four categories: dosage transparency (35 pts), label completeness (25 pts), formulation cleanliness (25 pts), and ingredient profile (15 pts). The score is based on data from the NIH Dietary Supplement Label Database, not marketing claims.
Does a higher score mean the supplement is more effective?
No. The SupplementScore measures label quality, how transparent, clean, and well-documented a product is. It does not measure clinical efficacy, bioavailability, or third-party testing. A higher score means better label practices, not guaranteed results.
How many heart health supplements were analyzed?
We analyzed 2,171 heart health products from the NIH DSLD database, which contains label data for over 116,000 dietary supplements sold in the United States.
