The body is used to that,\u201d study director Dr. David Nieman said in a press release. \u201cHigh vitamin D2 levels are not a normal experience for the human body. Taking high doses of vitamin D2 caused something to happen at the muscle level that isn\u2019t in the best interest of the athletes. Now we need others to test this and see if they come up with the same results.\u201d  Researchers from Appalachian State University observed significantly more exercise-induced muscle damage in NASCAR pit crew athletes taking vitamin D2 supplements derived from Portobello mushroom powder. This finding was a surprise, as the researchers had hypothesized that supplementation would benefit athletes by reducing inflammation and improving muscle recovery. Vitamin D3 has previously been shown to improve muscle function.  \u201cJust about everyone has lower vitamin D levels in the winter,\u201d Nieman said. \u201cWe know that when you restore vitamin D levels in older people it improves their muscle function. What hasn\u2019t been documented is if the same holds true for younger adults. We were interested in seeing if increasing vitamin D in the pit crew athletes who train heavily in the off season would improve their muscle and immune function. While vitamin D2 levels in the blood increased, we found that levels of the valuable D3 decreased. And to our surprise, those taking vitamin D2 didn\u2019t have just a little more muscle damage, they had a lot more damage.\u201d  Click here to read the press release from Appalachian State.  &nbsp;  &nbsp;  &nbsp;  SmartTan.com news articles regularly report medical and scientific information to keep you abreast of current events related to UV light.
