Time to Increase Vitamin Dby PNI on March 29, 2015 , no comment. Now that the clocks have turned back, it’s that time of year again: Cold & Flu Season. As the days become progressively shorter with less sunlight, now is a good time to increase your intake of Vitamin D to help boost your immune system. Vitamin D is commonly referred to as the “sunshine vitamin” because it’s produced in your skin in response to sunlight. Vitamin D is a fat-soluble vitamin in a family of compounds that includes vitamins D1, D2, and D3. It can affect as many as 2,000 genes in the body. If you’re under the impression that Vitamin D is mostly a nutrient for your bones you may be surprised to learn that it is vital to your health in other areas. Most people also think that vitamin D is a vitamin (hence the name), but in reality the active form of vitamin D is one of the most potent hormones in your body, and regulates more genes and bodily functions than any other hormone yet discovered. Vitamin D is produced as a pro-hormone in your skin after exposure to sunlight, and is then converted to the potent hormone form. Without this hormone, you could die: and indeed many people do die from Vitamin D deficiency-related causes. Vitamin D could rightly be described as a “miracle nutrient” for your immune system, as it enables your body to produce well over 200 antimicrobial peptides, which are indispensable in fighting off a wide range of infections. As an example of how powerful Vitamin D is for health: a Japanese study showed that school children taking vitamin D3 supplements were 58 percent less likely to catch influenza A. That’s a higher effectiveness than any flu vaccine can claim, and it doesn’t come with a barrage of potentially devastating side effects! And there are numerous other studies showing the superior effectiveness of natural strategies like vitamin D in the prevention of disease. As it’s already been stated, our bodies produce vitamin D naturally through direct exposure to sunlight, and a little can go a long way: just 10 minutes daily of mid-day sun exposure is plenty, especially if you’re fair-skinned. Besides getting vitamin D through sunlight, you can also get it through certain foods and supplements. The National Institute of Health recommends that you obtain vitamin D from all three of these sources in order to ensure adequate levels in your blood. For you guys, PNI has incorporated Vitamin D into our male support formula, Paragon. There has been some controversy over the amount of vitamin D needed for healthy functioning. Recent research indicates that we need more vitamin D than was once thought. Some sources suggest that considerably higher daily amounts of vitamin D – as high as 2000 IU per day – are needed, and many medical experts emphasize that as people age their requirements become higher than younger people. Although the exact amount may be in question, the importance of Vitamin D is not. There’s no doubt that the best defense against any disease such as the Flu is to have a strong immune system. So this Winter, increase your intake of Vitamin D and experience hopefully a healthier Winter.

Vitamin D može smanjiti mogućnost pojave raka dojke Studija naučnika s University of California iz San Diega pokazala je da kod žena sa potvrđenom visokom razinom vitamina D u organizmu, postoji i do 50% manji rizik obolijevanja od raka dojke. Čak je i blago povišena razina vitamina D bila povezana s 10%-tnim smanjenjem rizika za pojavu bolesti, utvrđeno je u istraživanju u kojem je sudjelovalo više od 120000 ispitanica. Vitamin D se u organizmu proizvodi nakon izloženosti sunčevoj svjetlosti, a prisutan je i u ribi, posebno onim vrstama koje obiluju uljem. Viši unos vitamina D se posebno preporučuje starijim osobama. Naučnici upozoravaju kako pretjerana izloženost suncu može imati negativan utjecaj na zdravlje te dodaju kako previsoka razina vitamina D u organizmu može dovesti do opasnog povećanja količine kalcija. Dakle pazite da ne pretjerujete, te održavajte optimalnu razinu vitamina D u organizmu.
