A vitamina D aumenta a sua imunidade?

As the days begin to get cooler and the amount of sunlight begins to fade, our ability to naturally get the ideal amount of vitamin D in sunlight begins to diminish. Even in the summertime, especially in the northern hemisphere it’s particularly tough to receive your entire quota of vitamin D.

Vitamina D

In reality vitamin D deficiency is widespread in the UK, with 1 in 5 adults with low levels. We are living in a time where sunlight exposure is considered by some to be a health menace. In an effort to decrease skin cancer, we’ve encouraged people of all ages to wear sunscreen and protective clothing and invest more time in shaded locations. Sensible sunlight without sunscreen it a fantastic way to up ingestion of vitamin D without burning. This will not unduly raise the danger of skin cancer.

Yet the complex cancers associated with vitamin D deficiency such as ovarian, esophageal, breast, breast, thyroid and prostate cancer far outweigh skin cancer diagnosis. Over three fourths of the advanced cancer patients have low levels of vitamin D. Research suggests that vitamin D has anti-tumour properties, regulating genes involved in the multiplication and spread of cancer cells. Vitamin D was wrongly categorised as a vitamin, in reality it’s not a vitamin at all.

Hormonal factor

It’s a steroid hormone which affects virtually every cell in your body. From your heart to your mind, to your immune system, keeping optimal vitamin D levels is extremely important. Vitamin D is a crucial anti inflammatory hormone. Vitamin D is essential for insulin secretion, so is a significant part of glucose metabolism. Those individuals with a very low blood (serum) degree have a greater risk of cardiovascular disease.

Vitamin D prevents the intrusion of calcium into cardiovascular cells from the bones, increases HDL cholesterol and reduces LDL cholesterol. It helps control the hormone renin, which regulates blood pressure and decreases the growth of vascular smooth muscle that narrows arteries, also raising immune tolerance and reducing inflammation.

Supplementing with vitamin D is a significant health essential. The sort of vitamin D supplement is critically important, physicians often prescribe vitamin D2 (ergocalciferol) supplements, rather than D3 (cholecalciferol). There are numerous biological mechanisms that lead to the superior absorbability and efficacy of Vitamin D3. In the liver, as a result of a distinct hepatic enzyme, vitamin D3 is more easily metabolized to a bioactive form of vitamin D, which can be easily converted into its hormone type in the kidneys. It takes much more time to create this hepatic conversion with vitamin D2.

Clearly, these kinds of vitamin D are not the same, and so the excellence of vitamin D3 supplements is important to understand. There’s no recommended intake in the UK except the older (400 iu or 10 mcg every day). The concern about toxicity of vitamin D in high levels is because of the potential of extra calcium, which can cause plaques in blood vessels. The expert panel on minerals and vitamins in the UK acknowledges 4000 iu daily as a safe dose.

Tomar nota

Human trials have shown 10,000 iu daily to be secure and a 5 year research indicates 40,000 iu is not likely to be toxic.

  • Fatty fish, such as tuna, mackerel, and salmon.
  • Foods fortified with vitamin D, like some dairy products and soy milk. Vitamin D may affect glucose levels.

Caution is advised if you’re taking diabetes medicine by mouth or insulin, you should be monitored closely by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary. Vitamin D may influence blood pressure and related medications. Vitamin D may interfere with how the body processes certain drugs using the liver’s”cytochrome P450″ enzyme system. Because of this, the amount of the drugs may be changed from the blood and can cause altered effects or adverse reactions. The very same responses apply to herbs and other nutritional supplements for blood sugar control, blood pressure and other support systems. Consult your doctor and pharmacist about potential interactions.
