Blood vessel walls can harden and then pose a risk of life-threatening cardiovascular disease. Vitamin D can loosen the hardening and repair blood vessels within a few weeks.
Vitamin D protects blood vessels
Cardiovascular diseases are known to be the most common cause of death in industrialized countries – and vitamin D deficiency is particularly widespread there. The connection between vitamin D deficiency and cardiovascular risk has long been undisputed. Because studies show several mechanisms through which vitamin D can protect the cardiovascular system from diseases.
- For example, vitamin D regulates the so-called renin-angiotensin-aldosterone system, which becomes overactive in the event of a vitamin D deficiency and narrows the blood vessels, which can contribute to hardening.
- Vitamin D also suppresses the migration of smooth muscle cells into the innermost blood vessel wall, the activation of macrophages, and the calcification of the blood vessel walls. All of these processes would otherwise thicken and harden the blood vessel walls, destroy their flexibility, lead to arteriosclerosis and ultimately result in a heart attack or stroke.
- We have also already explained here (vitamin D for the heart) that cardiovascular diseases develop as a result of chronic inflammation in the blood vessels. In addition to poor nutrition, it is a vitamin D deficiency that can lead to these inflammations, because vitamin D protects against inflammation.
- Since vitamin D also helps to regulate cholesterol levels, vitamin is important for the prevention of cardiovascular diseases in several ways.
Hardening of the blood vessel walls decreases after only 4 months
In a study by Augusta University in Georgia/USA, 70 women, all of whom already suffered from various degrees of hardened blood vessels, were given different doses of vitamin D for 4 months. This was the first randomized study of its kind. It found that vitamin D supplementation can improve the hardening of blood vessels in a dose-dependent manner.
Those participants who received the highest dose (4,000 IU) achieved the best results, study author Dr. Anas Raed. It is interesting that it is five times the amount that is officially recommended (800 IU). The health authorities apparently warn against doses that would actually be helpful and healing.
Taking 4,000 IU per day, participants experienced a 10.4 percent reduction in the hardening of the arteries in just 4 months.
“We have a significant and rapid reduction in hardening of the arteries here,” says Raed.
Officially recommended dose of vitamin D further hardens blood vessels
2,000 IU of vitamin D – still more than officially recommended – had little effect. Hardening of the arteries decreased by only 2 percent. At 600 IU (as advised by the American health authorities) there was even a slight worsening of the blood vessel situation. In the control group, which did not take any vitamin D at all, the problem increased by 2.3 percent.
Already in 2015, Dr. Dong published a study that had already shown that a dose of 4,000 IU of vitamin D was able to correct vitamin D deficiency significantly better and faster than 2,000 IU. In addition, the higher dose had a more beneficial effect on bone health.
Vitamin D for the blood vessels
dr Dong, an expert on vitamin D, advises spending at least 15 minutes in the sun every day, between 10 a.m. and 2 p.m. Sunburn must of course be avoided. According to Dong, the sun is the best source of vitamin D there is. Since many people are in offices or other premises at the time in question, vitamin D supplements are an inexpensive and safe alternative to keep blood vessels healthy.
Vitamin D can be dosed particularly easily and flexibly if you take it in the form of drops, e.g. B. vitamin D3 drops from effective nature. Just 1 drop delivers 1,000 IU.
