6 Best Vitamins to Prevent Calcium Plaque in Your Arteries and Heart

todicamp

Heart health is a critical aspect of overall well-being, and maintaining healthy arteries is key to preventing heart disease. Calcium plaque buildup in arteries can lead to atherosclerosis, a condition where the arteries become narrow and stiff. This can significantly increase the risk of heart attacks and strokes, making it essential to find ways to keep arteries clear. Understanding the role of certain vitamins in preventing arterial calcification is a crucial step in this process.

 

In this article, we’ll explore the top 6 vitamins with proven benefits for keeping your arteries healthy and plaque-free.

1. Vitamin D3

 

Vitamin D3 Known as the “sunshine vitamin”, Vitamin D helps regulate calcium absorption and supports immune function. Studies show it also suppresses inflammatory cytokines implicated in atherosclerosis while stimulating proteins that prevent plaque calcification.

 

Individuals with vitamin D deficiency have significantly higher coronary artery calcium scores compared to those with optimal levels. Ensuring adequate blood levels of vitamin D through sun exposure, food sources and supplementation appears protective against plaque accumulation.

 

How Vitamin D3 Protects Arterial Health

 

Vitamin D3, specifically, is the form of vitamin D produced in the skin during sunlight exposure. Multiple research studies demonstrate that vitamin D3 helps prevent atherosclerosis and arterial calcification through several mechanisms:

 

  • Regulates Calcium Metabolism: Vitamin D3 maintains healthy levels of calcium and phosphate, preventing calcification of soft tissues. It enhances intestinal absorption of calcium, while at the same time enabling the kidneys to excrete excess calcium. It stimulates the production of osteocalcin, a protein hormone that helps deposit calcium into bones and teeth where it belongs.

 

  • Reduces Inflammation: Vitamin D3 lowers levels of inflammatory cytokines including IL-6 and TNF-a. Chronic inflammation is known to damage arterial walls and promote plaque formation.

 

  • Inhibits Vascular Cell Growth: Vitamin D3 derivates known as analogs can restrict the multiplication of vascular smooth muscle cells. The vitamin D receptor also controls genes involved in cellular proliferation, differentiation, and apoptosis. The uncontrolled growth of these cells contributes to atheromatous plaques within arteries.

 

  • Protects Endothelial Function: The endothelium is the inner arterial lining crucial for maintaining vascular health. Vitamin D3 has been shown to improve endothelial function by reducing endothelial oxidative stress and increasing nitric oxide bioavailability. Vitamin D3 preserves endothelium-dependent dilation and nitric oxide signaling. Endothelial dysfunction is tied to the development of atherosclerotic disease.

 

Multiple clinical studies reveal that adults with adequate 25(OH)D levels above 30 ng/mL have significantly lower coronary artery calcium scores and slower plaque progression over time versus those who are vitamin D deficient.

 

Additional studies have also shown that high-dose vitamin D supplementation (around 4000 IU daily) causes a decrease in arterial stiffness compared to placebo, suggesting a reduction in vascular calcification.

 

Aim for at least 2,000-4,000 IU daily of vitamin D3 to meet general health guidelines. Testing your 25(OH)D blood levels can also help determine your ideal dosage for optimizing cardiovascular protection.

2. Vitamin K2

 

Vitamin K2 Found in fermented foods and animal products, vitamin K2 or menaquinone activates proteins that help remove calcium from arteries and soft tissues, depositing it preferentially into bones and teeth.

 

The vitamin K-dependent matrix Gla protein is the main inhibitor of vascular calcification. Vitamin K2 activates matrix Gla protein, which can regress arterial calcification by blocking new calcium crystal formation and promoting osteoclastic action to break down calcified tissue.

 

A landmark Rotterdam study on 4,800 adults without heart disease found that participants with high K2 intake had a 52% lower risk of severe aortic calcification and 57% lower death risk from heart disease over 10 years. This highlights vitamin K2’s protective importance in preventing cardiovascular events.

 

How Vitamin K2 Prevents Arterial Calcification

 

Several mechanisms explain how this fat-soluble vitamin inhibits calcium deposition within arterial walls:

 

  • Activates MGP Protein: Vitamin K2 uniquely activates matrix gla-protein (MGP), which protects soft tissues from calcification. It transports calcium directly out of arteries.

 

  • Inhibits Irregular Crystallization: Arterial plaque contains irregular nanocrystals that induce inflammation and plaque rupture. Matrix Gla protein activated by vitamin K2 can inhibit the growth and aggregation of these dangerous crystals. It suppresses crystallization, promoting calcium solubility so it won't solidify into hazardous deposits.

 

  • Synergizes Vitamin D3 Activity: As mentioned, vitamin K2 perfectly complements vitamin D3 functions for shuttling calcium into proper areas like bones while preventing it from accumulating in places it shouldn’t - like blood vessels.

Among a cohort of postmenopausal women, research showed that adequate intake of both vitamins D3 and K2 more than halved the progression of coronary artery calcification compared to women deficient in both nutrients over three years.

 

Alongside calcium metabolism, vitamin K2 has been found to beneficially impact vascular stiffness. Supplementation with vitamin K2 for six weeks significantly decreased arterial stiffness in healthy postmenopausal women.

 

For optimal cardiovascular protection, health experts recommend 90-120 mcg daily of bioavailable vitamin K2 along with vitamin D supplementation. Testing your vitamin K2 levels can also help determine your perfect personal dosage.

3. Magnesium


After calcium and potassium, magnesium is the most abundant dietary mineral in the human body and plays essential roles in muscle, nerve, and cardiovascular function. Research suggests magnesium offers unique benefits for preventing calcium-related stiffening of arteries associated with atherosclerosis.

 

How Magnesium Prevents Arterial Calcification Here's a closer look at the mechanisms behind magnesium's protective cardiovascular effects:

 

  • Regulates Calcium Balance: Over 300 enzymes in the body require magnesium to properly catalyze reactions, including those that maintain calcium homeostasis. As the body’s calcium regulator, magnesium competes with calcium for reabsorption in the kidney tubules. This prevents hypercalcemia while stimulating calcitonin to deposit excess calcium into bones. Magnesium prevents excess calcium accumulation in soft tissues like blood vessels and arteries.

 

  • Prevents Cardiovascular Calcification: Studies utilizing coronary artery calcium (CAC) scores show individuals with low serum magnesium levels exhibit 2-3 times faster CAC volume progression over one year compared to those with adequate magnesium status. Magnesium intake is also associated with having a lower thickness of the inner two layers of the carotid arteries. This confirms magnesium inhibits atheromatous plaque formation.

 

  • Supports Vascular Flexibility & Function: Magnesium helps blood vessels remain flexible and relaxed by mediating vascular smooth muscle function. It regulates calcium spiking in vascular smooth muscle cells to prevent arterial rigidity. It stimulates the production of prostacyclin PGI2, a compound that prevents dangerous blood clots and atherosclerotic lesions within arteries.

 

Given the research, consuming adequate magnesium is crucial for keeping your cardiovascular system healthy and plaque-free. Studies show that increased magnesium intake can slow the progression of coronary artery calcification.

 

Supplementing with approximately 350-500 mg daily of bioavailable magnesium glycinate, malate or citrate forms can support healthy magnesium levels without GI side effects.

 

Also include magnesium-rich foods like spinach, Swiss chard, pumpkin seeds, almonds, and legumes regularly in your diet.

4. Phytic Acid


Found abundantly in grains, nuts, seeds, and beans, phytic acid or phytate plays important yet overlooked roles in human health. Research now shows it can help deter soft tissue calcification too.

 

Also known as IP6, phytic acid is the storage form of phosphorus in plants. It has a unique structure that allows it to bind strongly to minerals like calcium, iron, and zinc.

 

This same mineral-chelating ability enables IP6 to extract calcium directly from hydroxyapatite deposits found in arterial plaque and other tissues. Studies demonstrate it also inhibits the formation of new hydroxyapatite crystals.

 

Its effectiveness at reducing calcification makes phytic acid a promising supplemental therapy for atherosclerosis prevention and treatment.

 

How Phytic Acid Prevents Atherosclerosis

 

Multiple research studies have examined phytic acid’s ability to prevent atherosclerotic lesions within animal models:

 

  • Rodent studies show phytic acid injections reduce aortic plaque lesions by 60-70% compared to lesion size in control groups.

 

  • Rabbits fed diets containing 2-3% phytic acid develop 70% less fatty lesion coverage in their aortas relative to positive controls.

 

  • Chickens given phytate compounds exhibit nearly 10 times reductions in abnormal calcium deposition within arteries versus untreated poultry.

 

The calcium chelation capabilities of phytic acid are believed to inhibit calcification by suppressing apatite crystal growth and nucleation.

 

Population studies associate high dietary phytate intake with up to 65% decreased atherosclerosis progression in humans over two years as well. Exact mechanisms are still being unraveled but likely relate to IP6 limiting calcification and crystallization within atheromatous plaque lesions

.

To boost your phytic acid intake, emphasize beans, lentils, nuts, seeds, whole grains, and isolated phytate supplements in your regular diet.

5. Vitamin C

 

Known for its immune-boosting properties, vitamin C or ascorbic acid also contributes to cardiovascular health in the following ways:

 

  • Improves Cholesterol Levels: With its antioxidant activity, vitamin C protects LDL cholesterol particles from oxidation—a key early step in atherosclerosis development. Human trials show just 500 mg/day of supplemental vitamin C decreases oxidized LDL by over 30% while raising HDL “good” cholesterol levels by 5-15% on average.

 

  • Stabilizes Arterial Plaque: Accumulating data demonstrates that patients with low vitamin C levels exhibit a faster progression of coronary artery plaque than those with higher intake levels. By protecting lipids and proteins against oxidative damage, vitamin C prevents endothelial injury and inflammation that destabilizes plaque. Sufficient vitamin C may help stabilize or retard atherosclerosis advancement.

 

  • Lowers Cardiovascular Risk: Several large-scale studies reveal a relationship between higher blood vitamin C concentrations and reduced prevalence of stroke, coronary artery disease, and cardiovascular death. Analysis of 85,000 adults found those with the highest plasma vitamin C had a 42% lower risk for stroke.

 

Through its potent antioxidant effects, vitamin C averts LDL oxidation involved in early atherosclerosis while improving endothelial function for overall vascular protection.

 

While more research is warranted, current evidence indicates vitamin C protects against atherosclerosis while optimizing several risk factors for adverse cardiovascular events like myocardial infarction and stroke.

 

Aim for at least 500mg daily of vitamin C through a combination of citrus fruits, peppers, broccoli, kiwi, and possibly supplementation if deficient.

6. Vitamin E

 

Known primarily for its antioxidant properties, vitamin E may also help individuals with peripheral arterial disease or PAD slow atherosclerotic progression.

 

How Vitamin E Impacts PAD

 

PAD involves the narrowing of leg arteries from plaque accumulation, causing pain, poor wound healing, and mobility issues.

 

The HOPE-2 trial had PAD patients supplement daily with 200 IU vitamin E and this group showed an average of 5.8% increased treadmill walking distance after one year while the placebo group declined by 10.5%.

 

Beyond improving endothelial vasodilation and arterial stiffness, vitamin E is believed to protect PAD patients through its ability to inhibit LDL oxidation and oxidative damage driving atherosclerosis.

 

So vitamin E shows potential benefits for those with PAD, however...

 

Limitations Exist

 

Larger studies on vitamin E supplementation like HOPE-TOO faced challenges demonstrating protective cardiovascular effects:

 

  • While 200 IU vitamin E modestly reduced coronary artery calcium scores, it failed to significantly protect against heart attack, stroke, or cardiovascular death over 7 years.

 

  • Concerns emerged over increased heart failure risk among certain segments taking high-dose (400+ IU) long term. This requires further research before drawing conclusions.

 

Despite promising data on vitamin E improving PAD symptoms, larger trials have been unable to confirm clear cardiovascular benefits. More research is still needed to establish its efficacy.

 

So while vitamin E holds promise for improving some facets of PAD and atherosclerosis, its optimal dosing and ability to prevent adverse cardiovascular events remains controversial until more evidence clarifies its effects.

 

Conclusion


Atherosclerosis leading to heart attack and stroke remains a leading cause of morbidity and mortality worldwide. Complications often result from plaque calcification and calcium deposition within arterial walls over time.

 

Fortunately, research shows certain vitamins like D3, K2, magnesium, phytic acid, and vitamin C can inhibit soft tissue calcification and reduce plaque progression through various mechanisms.

 

Ensuring adequate intake of these vitamins through dietary sources and possibly targeted supplementation may provide additional protection against life-threatening cardiovascular complications.

 

As always, consult your doctor about advanced lab testing and personalized nutritional advice for keeping your arteries healthy and plaque-free long into older age.
