Yea, this study basically cannot be not bullshit. -> i mean the study surely is Bullshit (99.999%)
Side effects of too much Vitamin D:
Elevated Blood Levels. ...Elevated Blood Calcium Levels. ...Nausea, Vomiting and Poor Appetite. ...Stomach Pain, Constipation or Diarrhea. ...Bone Loss. ...Kidney Failure.
Although a vitamin D level of 30 ng/ml (75 nmol/l) is typically considered adequate, the Vitamin D Council recommends maintaining levels of 40'80 ng/ml (100'200 nmol/l), and states that anything over 100 ng/ml (250 nmol/l) may be harmful (6, 7).Despite the fact that more people are now taking vitamin D supplements, it\'s rare to find someone with very high blood levels of this vitamin.One recent study looked at data from more than 20,000 people over a 10-year period. It found that only 37 people had levels above 100 ng/ml (250 nmol/l). Only one person had true toxicity, at 364 ng/ml (899 nmol/l) (.In one case study, a woman had a level of 476 ng/ml (1,171 nmol/l) after taking a supplement that gave her 186,900 IU of vitamin D3 per day for two months (9).This was a whopping 47 times the generally recommended safe upper limit of 4,000 IU per day.The woman was admitted to the hospital after she experienced fatigue, forgetfulness, nausea, vomiting, slurred speech and other symptoms (9).Although only extremely large doses can cause toxicity so rapidly, even strong supporters of these supplements recommend an upper limit of 10,000 IU per day (3).
A daily intake ranging from 40,000'100,000 IU (1000'2500 micrograms), for one to several months, has been shown to cause toxicity in humans (14, 18, 19, 20, 21).
Taking 60,000 international units (IU) a day of vitamin D for several months has been shown to cause toxicity.
So 10 000 IU daily for long term seems to be upper limit And i guess 20 000 iu daily for 1 month is ok. Especially in the winter. Anyway, so i bought this,
so i will do this for a month, i want to take vitamin D anyway in the winter

But didn't everyone in the study take it daily? I also read that there wasn't much risks taking it does it mean that they lied?
The only known risk of large dosages of vitamin D 3 is excessive blood calcium levels with potential kidney damage. For that reason, individuals taking the large dosage of D 3 are advised to avoid calcium supplements.
If you want to know the issues, just do some research. For example:
I think you guessed right @Dream. I\'ve read some of Shealy\'s stuff, and he does know a lot about natural health, etc. The guy is in his 80s and looks freakin great. But I strongly suspect this has to be bullshit for the following reasons:
1. If something sounds way too good to be true, it usually isn\'t. Average gain of 0.5\" Girth from vitamins? One guy gained over an Inch in Girth? Really??
2. There is no way a successful study of this magnitude, done in 2009, would not have been followed up or replicated. It just does not make sense.
3. Shealy wrote a paper in 1995 that references another paper by Brian Richards on \"the Chartham method\" paper... remember this being discussed on thunders and pegym ... its basically jelquing and pumping...again, never replicated, results sound too good... I figured 10 years ago that was also BS. In fact, I even tried it! (ps..dont ever jelq).
If anyone wants to wager 10K USD that this will never be replicated, with a timeframe of 5 years. let me know... I accept paypal, lol.
