Vitamin D3: Feed
Vitamin D: How much do you need and how to ensure a sufficient supply
Vitamin D is essential for strengthening the immune system and has a positive effect on the function of the brain, the heart and mental health.
Also for the preservation of bone density and muscle health, it is essential, as it promotes the absorption of calcium, magnesium and phosphorus.
Its deficiency causes different symptoms, especially bone and muscle pain and severe tiredness.
The minimum amounts that must be taken daily to achieve adequate vitamin D levels are as follows:
Kids under one year - 400 IU
Kids up to 13 years - 600 IU
-Adults and pregnant women - 600 to 800 IU
Vitamin D is found in animal foods, vegetable sources are scarce.
The trend of vitamin D use
Since 2000, the potential health benefits of vitamin D are explored strengthened. The recommended vitamin D intake is 600 IU / day for adults to 70 years and 800 IU / day for adults over 70 years. The tolerable upper limit is 4,000 IU / day. Above this level the risk of toxic effects increases.
Using data from the baseline survey National Health and Nutrition Examination Survey trends were D-vitamin use rates in 1999-2014. Around 39,300 participants were evaluated. The average age was 46.6 years (SD: 16.8), and 51.1% were female. The prevalence of additional vitamin D intake of 1000 IU / day or more was 2013 to 2014 at 18.2% (95% confidence interval [CI]: 16.0% to 20.7%), higher than 1999 to 2000 (0.3%; 95% CI: 0.1% to 0.5%; P for trend <0.001).
Study on vitamins with 4,000 IU or more
In the period 2013-2014, the prevalence was an additional supply of 4,000 IU / day or more at 3.2% (95% CI: 2.5% to 4.0%). Before 2005-2006, the prevalence of supply was of 4,000 IU / day or greater in less than 0.1% (P for trend from 2007 to 2014: <0.001).
As for the features, it was 2013-2014 intake of 4,000 IU / day or more in women (4.2%; 95% CI: 3.0% to 5.7%), non-Hispanic whites (3.9 %; 95% CI: 3.0% to 5.1%) and those aged 70 years or older (6.6%; 95% CI: 4.2% to 10.2%) higher.
From 1999 to 2014 the number of US adults who take daily vitamin D supplements of 1,000 IU or more and 4,000 IU or more, increased. A total of 3% of the population / exceeded the tolerable limit of 4,000 IU a day and are thus exposed to potentially the risk of adverse effects and 18% have exceeded 1,000 IU / day. You can choose if you Vitamin D3 30000 IE or Vitamin D3 50000 want to buy IU doses.
Vitamin D and Multiple Sclerosis
- In recent years, relations between Vitamin D and autoimmune diseases and neoplasms were found, but they are not yet fully understood. It probably plays an important role in the pathophysiological process of multiple sclerosis, even if it is not fully understood. It is possible that low in patients with isolated demyelinisierendem syndrome (before the diagnosis of MS) serum vitamin D levels-can affect the relative risk of conversion to MS.
human metabolism
- The various scientific societies are still not in agreement on the optimal serum vitamin D levels to meet the needs of human metabolism. An in vitro study of peripheral blood cells from patients who are taking vitamin D, showed that a serum level of about 40 ng / ml of a modulating effect may have on cells of the immune system.
5,000 IU of vitamin D per day
- based on a study on healthy people, which showed that the taking of 5,000 IE vitamin D per day over a period of 15 weeks to increase the mirror to up to 60 ng / ml, became Cans of up to 10,000 IE per day considered to be sure to achieve the target of 40 to 100 ng / ml.
Side effects of vitamin D
- Side effects: The clinical image of a vitamin D-inxication can have different signs and symptoms: nausea and vomiting, anorexia, abdominal pain, constipation; Polydipsia, polyuria, dehydration, nephrolithiasis, nephocalcinose, nephrogenic diabetes insipidus, chronic interstitial nephritis, acute and chronic renal failure; Hypotension, paresthesia, mental confusion, convulsive crisis, apathy, coma; Arrhythmia, bradycardia, hypertension, cardiomyopathy; Muscle weakness, calcification, osteoporosis; Conjugate salary. Hypercalingemia is the most important side effect and indicates when it is observed in the laboratory on an inxication.
