Vitamin D Megadoses Beneficial and Safe for Elderly

Recommended Posts


High doses of vitamin D are safe for older people, according to new research that challenges the conclusions past studies that have suggested mega-doses of the vitamin pose a risk.
The findings, published in the Journal of the American Geriatrics Society, are based on an analysis of 236 nursing home residents given 20,000 IUs of vitamin D per week for a year, MedPage Today reports.
Lead researcher Timothy Green, of the University of British Columbia in Vancouver, and colleagues found that patients who took high-dose vitamin D for at least six months were able to boost their levels to appropriate concentrations without suffering ill effects.
They concluded giving high-dose vitamin D to nursing home patients is "feasible and safe and eliminates vitamin D insufficiency."
Seniors in assisted living are at risk of having low vitamin D levels because of reduced exposure to sunlight, and limited intake from food sources. Some studies have shown that giving vitamin D can reduce the risk of fractures and falls.
The American Geriatrics Society recommends 4,000 IU per day of vitamin D for older patients, but the new research suggests higher levels may offer benefits without raising risks.

I don't find that to be a "megadose". It's below the recommended daily dose.

It depends on what its prescribed for. I take 300,000 IU once a week. 

  • Vitamin D: 1 IU is the biological equivalent of 0.025 mcg cholecalciferol or ergocalciferol

      A pit bull owner is calling for a change to animal bylaws in Saanich, B.C., after her dog was viciously attacked by a cat.
      Javiera Rodriguez told CBC News a house cat attacked her pit bull while they were out for a walk with a group of six other pit bulls and their owners on Monday evening.
      "The cat actually ran towards the dogs and started swiping at [my] dog's face," Rodriguez said.
      Her three-year-old dog, Bandida, suffered scratches on the face, ears and chin. Rodriguez was also scratched in the attack. She described the cat as being average in size with white fluffy fur.
      Rodriguez said she was out for a walk with Bandida and a group of other pit bulls when the attack took place.
      Kyla Grover, the owner of two of the other dogs on the walk, said she couldn't believe what she saw.
      "At first I was just shocked that this cat would go after seven dogs," she said. "I thought it would get scared and run away but it never did."
      She said she stepped in to help halt the attack.
      "Bandida being a pit bull, I knew if something were to happen she would get blamed and I couldn't have that happen, so I just needed to get them apart," she said.
      Grover also received puncture wounds and scratches that had to be treated in an emergency room, which took  five hours she said.
      One of the owners of the cat, Del Thompson, has apologized and has paid for Rodriguez's veterinary bills.

      NEW YORK (Reuters Health) - Stand-up comedians have long joked that some things, like the actual components of chicken nuggets, are better left mysterious.

      Recently, Mississippi researchers found out why: two nuggets they examined consisted of 50 percent or less chicken muscle tissue, the breast or thigh meat that comes to mind when a customer thinks of "chicken."

      The nuggets came from two national fast food chains in Jackson. The three researchers selected one nugget from each box, preserved, dissected and stained the nuggets, then looked at them under a microscope.

      The first nugget was about half muscle, with the rest a mix of fat, blood vessels and nerves. Close inspection revealed cells that line the skin and internal organs of the bird, the authors write in the American Journal of Medicine.

      The second nugget was only 40 percent muscle, and the remainder was fat, cartilage and pieces of bone.

      "We all know white chicken meat to be one of the best sources of lean protein available and encourage our patients to eat it," lead author Dr. Richard D. deShazo of the University of Mississippi Medical Center in Jackson, said.

      "What has happened is that some companies have chosen to use an artificial mixture of chicken parts rather than low-fat chicken white meat, batter it up and fry it and still call it chicken," deShazo told Reuters Health.

      "It is really a chicken by-product high in calories, salt, sugar and fat that is a very unhealthy choice. Even worse, it tastes great and kids love it and it is marketed to them."

      The nuggets he examined would be okay to eat occasionally, but he worries that since they are cheap, convenient and taste good, kids eat them often. His own grandchildren "beg" for chicken nuggets all the time, and he compromises by making them at home by pan-frying chicken breasts with a small amount of oil, deShazo said.

      "Chicken nuggets are an excellent source of protein, especially for kids who might be picky eaters," said Ashley Peterson, vice president of scientific and regulatory affairs for the National Chicken Council (NCC), a non-profit trade group representing the U.S. chicken industry.

      According to the NCC, its member producers and processors account for about 95 percent of the chicken produced in the U.S.

      "This study evaluates only two chicken nugget samples out of the billions of chicken nuggets that are made every year," Peterson said. A sample size of two nuggets is simply too small to generalize to an entire category of food, she told Reuters Health.

      Two nuggets is a small sample size, deShazo acknowledged, and some chains have begun to use primarily white meat in their nuggets - just not the particular restaurants he visited.

      "Chicken nuggets tend to have an elevated fat content because they are breaded and fried. But it's no secret what is in a chicken nugget - most quick service restaurants have nutritional information posted in the store or on their website," Peterson said.

      "And every package of chicken nuggets in the grocery store by law contains an ingredient list and a complete nutritional profile, including fat content," she said.

      The brief chicken nugget exploration was not meant to be an expos? of the chicken industry or fast food generally, but to remind consumers that "not everything that tastes good is good for you," deShazo said.

      He and his colleagues chose not to reveal which chain restaurants they visited.

      Consumers aren't necessarily being misled, since much of the nutritional information they need is readily available, he said.

      "We just don't take the time to understand basic nutritional facts."

      Residents of Terrace, British Columbia, Canada woke recently at 7:30 AM to strange loud grinding and whining noises that lasted 10 minutes. Kimberly Wookey was one of three people who recorded and uploaded videos of the sound to YouTube. While this wasn?t the first time she had heard the odd noises, it was the first time she was able to record them. After her video post Wookey received messages from other residents across the province that also heard the noise wondering what caused it.

      There are reports of similar sounds from around the world with explanations varying. Wookey told CBC News, ?Well I have heard that it could be skyquakes. It could be something from the earth?s core. It could be something magnetic, like the magnetic fields around earth. I, I really have no clue.? The Geological Survey of Canada?s Honn Kao confirmed that the noise was not from any regional seismic activity. Biologists discounted ideas that the noise came from an animal. Despite other theories that the wailing came from a train, residents insisted that it did not come from the nearby tracks.

      After all the speculation, Alisa Thompson, City of Terrace spokesperson offered an explanation saying the mystery noise came from the hockey arena parking lot where a city worker was sharpening the blade of a grader. To spread the word, the City of Terrace posted the information on their Facebook page reading in part, ?Turns out?.. it was us. A City employee was preparing a grader for some work on Lanfear hill and produced that mysterious noise with the grader blade.? But Wookey is skeptical saying, ?I?ve heard graders before and I?ve heard trains before and that sound was nothing like that.? Wookey is not alone in her doubt. Others who heard the strange noise in Terrace have been vocal, commenting on the city?s post that they just don?t believe Terrace?s explanation. Thompson said that the city would work to replicate the sound with the grader to set conspiracy theories to rest.

      Harry Black won an incredible $31.7 million in the lottery. But the way he accomplished it is even more amazing.
      As the BBC reports, Black, from British Columbia, won the money thanks to his purchasing two tickets with identical numbers.
      "This is a wonderful surprise to all of us," said Kevin Gass of the British Columbia Lottery. "While it's not known how many people buy identical tickets for a draw, it is the first time in the company's recollection that we've had this unique sort of win."
      The $63 million jackpot was ultimately split four ways. Meaning that if Black had used his winning numbers on just one ticket, the jackpot would have been split three ways and he would have walked away with a still whopping $20 million.
      Black, 66, is not only a huge lottery winner, he's also patient. The Surrey resident has been playing the same lottery numbers since he was 31?which means he waited 35 years for his enormous payday.
      Black said he has always purchased two tickets with the same numbers.
      For the record, the winning numbers were 02, 10, 17, 19, 44 and 47.
      Black already knew he was holding the winning pair of tickets since April 13, but he didn't step forward to claim the jackpot until the end of May while making plans for how he'd spend the money.
      ?After this is done, I?ve got to get out of Dodge and do something I've never done in my entire life: Go on a holiday,? he told CTV.
      Interestingly, Black said he has no plans to retire on his winnings. Instead, he?ll use the proceeds from the jackpot to build a home and go on vacation. He also plans to share some of the winnings with friends and family.
      "I already got enough toys,? he said at the press conference where he was awarded his giant lottery check. ?I worked hard for them. Maybe I?ll have time to play with them.?
      Black said he?d never won more than $10 off a single ticket before. He purchased the two winning tickets at a local Chevron gas station.
