Excessive Vitamin D Linked to Heart Problem

Micronutrients, including the different vitamins and minerals, are needed in the body in just a small amount. However, the absence or excess of one of it can pose harm or even a disease condition. Just like vitamin D. Vitamin D is also known as calciferol. It is a one of the fat soluble vitamins that our body needs. It can be found in some foods like vegetables, fruits and dairy products. The amazing thing is that our body has an inactive vitamin D beneath the skin which requires sunlight to be active and be converted for use. Vitamin D is essential for calcium and phosphorus regulation.

With a low level of this vitamin, it may lead to a condition known as Rickets in children and Osteomalacia in adults. Both are having problems with weak bones or even malformation of bone structure. It also helps prevent Osteoporosis (brittle bones) in later life. Oppositely, vitamin D in higher quantity can cause toxicity. This is the difference between water-soluble vitamins and fat-soluble vitamins.

The latter cannot be excreted by the body easily and vice versa. In high amounts, vitamin D may lead to hypercalcemia (high calcium level) or even hyperparathyroidism (over production of parathyroid hormones). The scary part remains when tetany (uncontrollable muscle spasms due to excessive calcium level) occurs.

In a study held, author T. Jared Bunch, M.D. noted that high levels of vitamin D may cause atrial fibrillation (AF) compared to those with normal level. Patients in number of 132,000 had undergone blood test for a period of 1.5 years. It was then figured out that patients with above normal vitamin D level develop atrial fibrillation in about 2.5 times than the other. The recommended value of vitamin D that can be consumed every day is 600 IU to 4,000 IU, beyond will men excessive.

Atrial Fibrillation, on the other hand, is a heart condition wherein the heart beats irregularly. The atria, or the two upper portion of the heart, contracts in a either very fast of very slow manner. In return, the blood supply being pumped by the heart may not be enough or impeded. But this condition may or may not cause any sign. In severe cases, atrial fibrillation can lead to heart attack or stroke.

Jared Bunch explained that “the only way to know how much vitamin D you need, or if you need any at all, is by taking a blood test” . Consulting the doctor is also important in monitoring ones health.

According to the Vitamin D Council Organization, “because the body has a built in mechanism for preventing toxicity with vitamin D produced in the skin, there is no risk of vitamin D toxicity due to ultraviolet-B (UVB) exposure – whether from the Sun or a tanning bed.

Supplemental vitamin D bypasses this built-in protection and, if excessive amounts are consumed over a period of time, 25(OH)D blood levels can reach a point where toxicity is possible.”

  1. It is better to try to avoid supplements of vitamin D. Vitamin D, which is produced under the influence of ultraviolet radiation are enough for adults and children. This is one of those cases where an overdose of vitamin much more dangerous than the lack of it.

  2. Atrial Fibrillation is frequently resolved by increasing magnesium intake. What happens when Vitamin D status is increased is the body is able to absorb more calcium from the diet. Calcium tenses muscle fibres and excites brain neurones. e require magnesium to relax the muscle fibre and calm the neurone. BUT most people only get about half the daily recommended magnesium amount. So By correcting vitamin d deficiency you also correct calcium status BUT expose the deficiency status in magnesium. Afibbers is an site for those with AF and they have lots of good information on magnesium. Remember the levels of vitamin D these people had were above 100mg/l 250nmol.l almost double the 50~70ng/ml ranges humans achieve living near naked outdoors and far higher than generally achieved..

  3. If EMILY went to GRASSROOTSHEALTH website she would learn how much vitamin D3 is generally required to achieve a healthy natural vitamin d status.Just to get to around the natural level at which human milk is a complete Vitamin D replete food for human babies generally requires an extra 6000iu/daily.Of course magnesium deficiency requires more magnesium It’s no ones fault that grains now contain less magnesium than previously in the same way we have to understand the many reasons why particularly for city dwellers it’s increasingly difficult to get sufficient vitamin d from sunlight and how increase cortisol levels and corticosteroid use is depleting our Vitamin d status. Far far more people are vitamin d replete. Very few people are able to raise status above 100ng/ml and certainly those who do should check their magnesium/vitamin a/boron/vitamin K intakes.
