*Not all products in this category have an EFSA-approved health claim. Products with an EFSA claim are described as such in the text. For the other products, they are grouped under this theme based on traditional use or product formula. For specific health questions, we recommend consulting a doctor or orthomolecular therapist.

Cardiovascular health is not one supplement — it's a thoughtful stack that combines the most fundamental cofactors for the cardiovascular system. Omega 3 (EFSA-recognized), Q10 (mitochondrial), magnesium (rhythm), vitamin K2 (calcium routing) — plus for specific issues berberine for cholesterol and turmeric for inflammation modulation.
Which cardiovascular stack is right for you?
| Situation | Stack | Time |
|---|---|---|
| General prevention 40+ | Omega 3 + Q10 + magnesium + K2 | Daily |
| Statin user (Q10 recovery) | Q10 ubiquinol + omega 3 | Daily |
| Cholesterol theme | Berberine + omega 3 + turmeric + psyllium | Daily |
| Blood pressure theme | Magnesium + potassium-rich diet + omega 3 | With doctor |
| Family history of heart & vessels | Broad stack + lifestyle | Ongoing |
What is heart & vessels?
The cardiovascular system includes the heart and blood vessels — transported by blood that carries oxygen, nutrients, and hormones. Its health depends on: heart muscle function (cofactors Q10, magnesium), elasticity of blood vessels (omega 3, vitamin C, magnesium), healthy cholesterol profile (berberine, omega 3, psyllium), healthy blood sugar (berberine, magnesium), and no unwanted calcium deposits in vessels (vitamin K2).
The basic cardiovascular stack is omega 3 + Q10 + magnesium + vitamin K2. Omega 3 (EPA + DHA, 250 mg/day minimum for EFSA heart claim) is the most robustly supported. Q10 is essential for mitochondrial energy in the heart muscle — especially relevant for those 50+ and those using statins (statins suppress endogenous Q10 production). Magnesium supports heart rhythm. Vitamin K2 ensures that calcium is deposited in bones and teeth, not in blood vessel walls.
For specific issues, there are additional options. For elevated cholesterol, berberine (clinically researched for LDL reduction via a different mechanism than statins) can support. For chronic inflammation (associated with cardiovascular issues), turmeric may be useful. For specific fibrinolysis issues, there is nattokinase — but only after medical consultation due to interaction with blood thinners.
Important note: cardiovascular supplements are not a substitute for medication. For high blood pressure, high cholesterol, or heart rhythm disorders, medical care remains the basis. Supplements are complementary, and with medication use (statins, blood thinners, blood pressure medication), prior consultation with a doctor or pharmacist is essential — especially for high doses of omega 3, K2, nattokinase, and berberine.
Heart & Vessels and EFSA — what is scientifically recognized?
EFSA has not recognized an overarching cardiovascular claim. However, there are components with relevant recognized claims:
"DHA and EPA contribute to the normal function of the heart." (250 mg/day)
"Magnesium contributes to normal muscle function." (heart is a muscle)
"Potassium contributes to the maintenance of normal blood pressure."
"Vitamin K contributes to normal blood clotting."
Thresholds apply to daily intake that provides at least 15% RI.

How to use heart & vessels?
Simple basic approach to cardiovascular health:
- Standard cardiovascular base: omega 3 + Q10 + magnesium + K2.
- With statin use: ubiquinol Q10 to compensate for statin-induced suppression of endogenous Q10.
- For cholesterol issues: berberine + omega 3 + turmeric.
- For blood pressure: magnesium + potassium-rich diet (no potassium supplement without medical consultation).
- Vitamin K2 prevents calcium deposition in blood vessel walls — especially with high calcium supplementation.
- Always combine with diet, exercise, weight management, and not smoking.
- With anticoagulant use (warfarin, NOACs): high doses of omega 3, K2, and nattokinase require consultation.
Myths and misconceptions about heart & vessels
Myth 1: "A pill solves cardiovascular issues."
Supplements are a complement to lifestyle, not a replacement.
Myth 2: "The more supplements, the better."
Stacking doesn't work — choose a targeted stack and give it time.
Myth 3: "Supplements work acutely for cardiovascular health."
Cumulative effect, allow 4-8 weeks.
Myth 4: "All brands are equal."
Quality varies greatly — choose premium for targeted effect.

Frequently asked questions
Which supplements for heart and vessels?
Omega 3 + Q10 + magnesium + K2 — basic. Plus berberine and turmeric for specific issues.
Omega 3 for the heart — does it work?
EFSA-recognized claim 250 mg EPA+DHA/day.
Q10 with statins?
Statins suppress endogenous Q10 production. 100-200 mg ubiquinol supplementation.
Berberine for cholesterol?
Clinical research positive. EFSA claim not recognized.
Magnesium for the heart?
Crucial for heart rhythm — magnesium deficiency can cause arrhythmias.
K2 for the vessels?
Directs calcium away from blood vessel walls to bones/teeth.
Is Nattokinase safe?
With anticoagulant use: never without doctor's consultation.
Turmeric for heart?
Anti-inflammatory profile — especially relevant for chronic inflammation issues.
Potassium supplement?
Avoid without medical consultation — risk of hyperkalemia. Prefer potassium-rich diet.
For high blood pressure?
Medical care is paramount. Magnesium and omega 3 are supportive.
