Nattokinase has been investigated for its anti-atherosclerotic effects, with a large 1,062-participant clinical study demonstrating significant reductions in carotid intima-media thickness and plaque size at high doses (10,800 FU/day over 12 months).

A randomized trial in dyslipidemics showed that 100–200 mg/day of ubiquinol significantly improved flow-mediated dilation (FMD) of the brachial artery and increased nitric oxide bioavailability. CoQ10 also reduces LDL oxidation, which has direct anti-atherogenic relevance.

Valyl-prolyl-proline (VPP) is a fermented milk-derived lactotripeptide that inhibits ACE, reducing blood pressure and improving endothelial function. Combined with IPP in meta-analyses of RCTs, VPP contributes to significant reductions in SBP (−4.8 mmHg) and DBP (−2.2 mmHg). The 2024 PMC vascular review listed lactotripeptides (including VPP) among arterial health nutraceuticals.

Niacin (nicotinic acid) at pharmacologic doses (1,500–3,000 mg/day) raises HDL-C by up to 35%, reduces triglycerides and LDL-C, and reduces lipoprotein(a), directly addressing atherogenic lipid burden on arterial walls. Niacin also improves FMD and reduces carotid intima-media thickness in clinical trials. It has been used for arterial and lipid-related conditions since the 1950s.

Folate (the natural form of vitamin B9) reduces homocysteine levels, protecting the arterial endothelium from hyperhomocysteinemia-induced damage. A 2022 network meta-analysis included folate among vitamins assessed for arterial stiffness reduction. Clinical trials show folate supplementation improves FMD and reduces arterial oxidative stress.

5-Methyltetrahydrofolate (5-MTHF), the active form of folate, directly reduces homocysteine levels protecting arterial endothelium and improves endothelial NO availability. Unlike folic acid, 5-MTHF bypasses the MTHFR enzyme step, making it effective even in MTHFR polymorphism carriers who cannot efficiently convert folic acid. Clinical trials show improvements in FMD and reduction in PWV.

Vitamin C (ascorbic acid) is an antioxidant that improves endothelial function and arterial stiffness by scavenging reactive oxygen species that degrade NO. A randomized, double-blind crossover trial in hypertensive patients (1 g vitamin C plus 400 IU vitamin E, 8 weeks) significantly improved brachial FMD and reduced pulse wave velocity. A 2017 review confirmed multiple mechanisms linking vitamin C to arterial destiffening.

Vitamin D may improve endothelial function, reduce arterial stiffness, and decrease atherosclerosis risk by inhibiting the renin-angiotensin-aldosterone system and reducing vascular inflammation. A 2022 network meta-analysis included vitamin D3 (cholecalciferol) among vitamin supplements assessed for arterial stiffness reduction via PWV. Multiple observational studies associate vitamin D deficiency with increased arterial stiffness.

Vitamin D3 (cholecalciferol) is the most bioavailable form of vitamin D studied for arterial health. It inhibits the renin-angiotensin system, reduces vascular inflammation, and improves endothelial function. A 2022 network meta-analysis of 22 RCTs specifically included cholecalciferol among supplements assessed for arterial stiffness reduction.

Vitamin E (tocopherols) protects arterial walls from oxidative stress-induced endothelial dysfunction. A randomized crossover trial showed combined vitamins C and E (400 IU/day) significantly improved brachial FMD and reduced arterial stiffness (PWV and AIx) in essential hypertensive patients. Mechanistically, vitamin E inhibits LDL oxidation and reduces endothelial expression of adhesion molecules.

Vitamin K (particularly menaquinone/K2) activates matrix Gla-protein (MGP), which inhibits vascular calcification by directing calcium away from arterial walls. A 2017 Disease Markers review confirmed vitamin K's mechanisms include reversing arterial calcification and reducing arterial stiffness. Epidemiological data link higher vitamin K intake to lower aortic calcification scores.

Watermelon-derived L-citrulline improves endothelial function and reduces arterial stiffness by increasing nitric oxide production, enhancing vasodilation. Clinical trials show reductions in aortic pulse pressure, carotid augmentation index, and wave reflection in prehypertensive and hypertensive adults.

Zeaxanthin is a xanthophyll carotenoid that co-occurs with lutein in greens and accumulates in the arterial wall, reducing LDL oxidation, inhibiting arterial macrophage foam cell formation, and reducing arterial oxidative stress. Like lutein, it is supported by mechanistic and observational evidence for arterial protection, though large isolated RCT data are lacking.

Allium tuberosum (garlic chives) contains similar organosulfur compounds and flavonoids to garlic (Allium sativum) and has been used in East Asian traditional medicine for cardiovascular support. Limited scientific studies show some lipid-lowering and antioxidant vascular properties, but direct clinical evidence for arterial health is substantially weaker than garlic.

Cordyceps (Cordyceps sinensis/militaris) has been used in traditional Chinese medicine to improve circulation, vitality, and cardiovascular function. Preclinical studies show Cordyceps polysaccharides and cordycepin improve arterial blood flow and have anti-inflammatory effects in vascular tissue. Limited human clinical data suggest modest cardiovascular benefits, classified primarily as traditional use.

Maca (Lepidium meyenii) is a Peruvian root traditionally used by Andean populations to improve circulation, stamina, and cardiovascular vitality at high altitude. Preclinical data suggest macaenes and macamides have vasodilatory effects. Limited and mixed human clinical evidence exists; the traditional use for circulatory support is well-documented.

Pomelo (Citrus maxima/grandis) is a citrus fruit rich in naringenin, naringin, and vitamin C with arterial-protective properties similar to grapefruit. Traditional use in Southeast Asian medicine for cardiovascular and lipid conditions is documented. Limited scientific data exist for pomelo specifically; evidence is primarily extrapolated from its bioactive composition.

Reishi (Ganoderma lucidum) has been used in East Asian traditional medicine for cardiovascular support for over 2,000 years, classified as a tonic for heart and circulation. Preclinical studies demonstrate anti-atherosclerotic effects including inhibition of platelet aggregation, LDL oxidation reduction, and anti-inflammatory vascular effects. Human clinical evidence for direct arterial endpoints is limited.

Rosemary (Rosmarinus officinalis) has been used in European herbal medicine for circulatory and cardiovascular support since antiquity. Its bioactives (carnosic acid, carnosol, rosmarinic acid) activate Nrf2, inhibit NF-κB, reduce LDL oxidation, and have anti-thrombotic effects relevant to arterial health. The scientific evidence derives primarily from in vitro and animal studies.

Baicalin from S. baicalensis has demonstrated anti-atherosclerotic effects in preclinical research, inhibiting oxidative modification of lipids and inflammatory plaque progression. Clinical use in China for cardiovascular conditions including atherosclerosis is documented. No standalone human RCT for arterial health with skullcap has been verified.

S. japonica has been traditionally used for arteriosclerosis, documented in classical TCM pharmacopeias and ethnopharmacological reviews. Rutin and quercetin mechanistically support arterial integrity by inhibiting LDL oxidation and reducing capillary fragility. Preclinical evidence supports anti-atherogenic effects, though clinical trials are absent.
