When heart disease damages your arteries or blocks the heart’s blood supply, cardiologists have tools designed to stop the harm and restore blood flow. However, mainstream medicine struggles to heal deteriorating blood vessels or heart tissue.
Research conducted at Ohio State University reveals that a particular vitamin can facilitate the healing of the cardiovascular system where conventional medicine falls short.
The vitamin in question is vitamin D3, which the skin produces when exposed to sunlight. Studies at Ohio State University demonstrate that vitamin D3 aids in repairing damage to endothelial cells, which line the walls of blood vessels and heart chambers.1
This newly discovered capability is of significant importance, as no other nutrient or substance has been identified to assist in this type of repair.
Researcher Tadeusz Malinski emphasizes the significance of this discovery, stating that vitamin D3 is a cost-effective solution for repairing the cardiovascular system without needing to develop a new drug.
Malinski also notes that many heart attack patients have a deficiency in D3, which may not directly cause the heart attack but increases the risk of experiencing one.
Studies conducted by Malinski illustrate how vitamin D3 impacts endothelial cells, which play a crucial role in maintaining artery and heart health. These studies reveal that vitamin D3 significantly influences the body’s utilization of nitric oxide (NO), a molecule that affects the contraction and relaxation of artery walls, thereby regulating blood flow and preventing blood clots.
Moreover, the research indicates that vitamin D3 aids in healing cardiovascular damage resulting from conditions like high blood pressure, diabetes, and atherosclerosis. It also reduces the likelihood of heart attacks and minimizes oxidative stress that can harm arterial cells.
Malfunctioning endothelial cells can lead to conditions like high blood pressure and ischemic events such as heart attacks and strokes, but vitamin D3 can help counteract these risks.
Therefore, Malinski suggests administering vitamin D3 to individuals following strokes, heart attacks, or any other conditions involving compromised blood flow.
Recent research on the benefits of vitamin D3 suggests that it may alleviate the discomfort associated with Irritable Bowel Syndrome (IBS).
A review study conducted at the University of Sheffield in England reveals that vitamin D3 supplements can provide relief from IBS symptoms like bloating, diarrhea, constipation, and abdominal pain.2
About 15% of Americans suffer from IBS, and the Sheffield study indicates that many of them have a vitamin D3 deficiency.
As per the Sheffield researchers, individuals with IBS should undergo vitamin D level assessments.
IBS remains a challenge for modern medicine, with researchers yet to determine its exact cause, though diet rich in processed foods and chronic stress are known to exacerbate it.
However, vitamin D3 deficiency might also play a role. It is advisable for everyone to have their vitamin D levels checked through a blood test to determine the required supplementation. Evidence suggests that most individuals have significantly lower than the optimal vitamin D level of 60.
While many could benefit from high doses of D3, ranging from 10,000 to 20,000 units daily, few people follow this regimen, primarily due to misconceptions about potential toxicity at higher doses. There is still widespread ignorance surrounding this vital vitamin.
