If you suspect that you might have a vitamin D deficiency, you may want to consider getting a vitamin D blood test done as soon as possible. Most blood labs will provide you with the results within a few days, but you also have the option to get tested at home. You can find out your vitamin D level with a very simple and easy to take at-home blood sample collection kit. If your results are above the normal range, you may want to consider taking supplements. Remember, a high level of vitamin D may result in toxicity. It’s a good idea to get a blood test regularly if you know you might be in the risk category. How Does Vitamin D Blood Test Work? The most accurate way to determine the level of vitamin D in the body is by taking a vitamin D blood test. This test effectively measures the amount of vitamin D in the blood and can offer a quick idea of whether changes in your lifestyle and diet are needed. Some people are not deficient in vitamin D, but it can be difficult to tell if they’re in the normal range, and that is why a vitamin D blood test is a good idea if you’re worried about low levels, or just want to make sure you are on the right track. Therefore the test can be incrementally helpful for those who don’t have symptoms of vitamin D deficiency as it can help them prevent any future health problems that might be triggered by low levels of vitamin D. A vitamin D blood test is a valuable way to check your vitamin D levels at home or in laboratory settings, it is totally up to you. Such a blood test can show if you are below the recommended levels, and it’s easy to get a test as you can have it delivered to your house and taken whenever you have the time. The test can be ordered online and then sent to the laboratory for analysis. A simple home vitamin D test is available from online stores and clinics. It contains a finger-prick and a vial to collect your blood. A certified laboratory will examine your blood and determine the level of vitamin D in your body. It will also give you a range of values for your level. The results of a vitamin D blood test are useful in determining whether your body needs additional vitamin D. However, the value of vitamin D is not universally accepted, and there is a great deal of debate about how to interpret the results. An inaccurately interpreted test can also result in unnecessary treatments. The excess of vitamin D in the body can damage the kidneys and other organs, and excessive amounts can lead to osteoporosis, a condition that weakens bones and increases the risk of fractures. In general, the best way to determine your level of vitamin D is to get adequate testing and talk with your health care provider about taking supplements. In general, a vitamin D blood test is not particularly useful if you’re not willing to make changes in your diet and lifestyle. Rather, it is better to seek the advice of your health care provider and start making small lifestyle changes like stopping smoking, losing weight, and staying physically active. You can also take a supplement or try eating foods that contain vitamin D. It is also important to know the right amount of sun exposure to ensure you are getting adequate amounts of vitamin D. In general, you need at least twenty minutes in direct sunlight three times a week, but this varies by season and where you live. The sun’s rays are most effective between 10 a.m. and three p.m. Depending on your location, it may be necessary to take more or less time than this. A vitamin D blood test can be ordered to screen people at a higher risk for developing a disease. This way, the doctor can determine if someone has low levels of vitamin D before they start having problems. A deficiency in this vitamin can lead to fatigue and difficulty sleeping. Laboratories use different methods and samples to calculate the level of vitamin D. You should consult your doctor if you have a lower level of vitamin D than your doctor recommends, as this might help you avoid more serious health problems in the future. Why Vitamin D Is So Important? Vitamin D is a crucial nutrient that supports a healthy immune system and supports healthy bones. The vitamin also acts as an antioxidant, neuroprotector, and anti-inflammatory, supporting the immune system, muscle function, and brain cell activity. Although the sun’s ultraviolet rays don’t contain vitamin D naturally, fortified foods and exposure to the sun can provide enough of this essential nutrient. An at-home vitamin D blood test is a quick, convenient way to determine your vitamin D level.

Debljina uzrokuje manjak vitamina D Poznato je da debjina utječe na utječe na razvoj dijabetesa tipa 2, srčanih bolesti i određenih oblika raka U nedavnom izdanju časopisa PLoS Medicine objavljena je studija koja upozorava da debljina može uzrokovati manjak vitamina D. Ova je studija, koju su proveli istraživači okupljeni u zajedničkoj suradnji pod imenom D-CarDia u okviru Britanske zaklade za srce (British Heart Foundation), prva povezala visok indeks tjelesne mase (BMI) s niskim razinama vitamina D. Studija je obuhvatila više od 42.000 ljudi iz 21 zemlje, a unutar nje istraživači su pokušali prepoznati sve genetske varijacije kojr bi mogle biti povezane s indeksom tjelesne mase i vitaminom D kako bi bili sigurni da nijedan drugi čimbenik nije utjecao na rezultate. Visok indeks tjelesne mase povezan s niskim razinama vitamina D Istraživači su otkrili da je povezanost između visokog indeksa tjelesne mase i niskih razina vitamina D svojstvena svim demografskim skupinama. Svako povećanje indeksa tjelesne mase za 10 posto uzrokovalo je padom razine vitamina D od 4,2 posto. „Pokazali smo da je povezanost između indeksa tjelesne mase i vitamina D prisutna kod svih bijelaca Sjeverne Amerike i Europe bez obzira na dob ili spol. Dokazali smo i da povećanje indeksa tjelesne mase dovodi do smanjenja vitamina D, a time i da pretilost predstavlja rizik za nedostatak vitamina D", izjavili su autori, podsjećajući kako je vitamin D nužan za zdravlje kostiju i sprečavanje bolesti poput raka, dijabetesa i visokog krvnog tlaka. Nedavno istraživanje provedeno na Sveučilištu u Kopenhagenu otkrilo je kako niske razine vitamina D mogu povećati rizik obolijevanja od srčanih bolesti i prerane smrti. „Naša studija ističe nužnost povećanja razine vitamina D kod pretilih osoba, kao i važnost praćenja i tretiranja nedostatka vitamina D kako bi se smanjili nepovoljni učinci pretilosti na zdravlje. Smanjenje pretilosti u populaciji trebalo bi dovesti i do smanjenja učestalosti nedostatka vitamina D", izjavili su autori istraživanja. Debljina i niske razine vitamina D povezane su s rizikom od dijabetesa Moguće je i da bi pretilost mogla utjecati, osim na smanjenje razine vitamina D, i na razvoj dijabetesa tipa II. Istraživači su otkrili da je rizik za razvoj inzulinske rezistencije veći kod osoba koje su i pretile i imaju nizak vitamin D, nego kod osoba kod kojih je samo jedan od tih dvaju čimbenika izražen. Shaum Kabadi i njegov tim sa Sveučilišta Dextrel otkrili su kako pretili ljudi s normalnom razinom vitamina D imaju čak 20 puta veći rizik za razvoj inzulinske rezistencije u usporedbi s ostatkom populacije. No, rizik kod pretilih ljudi s niskom razinom vitamina D veći je čak 32 puta.
