I've been doing alot of research on Vitamin D, and so I fully understand how it affects your skin as well as the significant differences in RDA amounts preached by various doctors/organization. And yes, I do know that there are many factors that affect your skin and sometimes a good diet is not enough for some people. As a former athlete and current gym rat I am literally the picture of physical health, and even with a super clean and healthy diet, plenty of sleep, and no drugs or alcohol I still have crappy skin. Specifically I have extremely oily skin, and after reading the original post I am curious if anyone has had as drastic a skin reversal as he did using Vitamin D.
And I really don't understand all the questions in your post Alternativista. Most doctors are not bad at their job. Years and years of education means that they are well versed in diagnosing the majority of general problems people have. With that being said, you can't expect one person to be able to be knowledgeable about EVERY gentically possible ailment that may be presented to them. As with anything, doctors have their limitations in diagnosing things but they are not bad at their job. And as for your cholesterol comment, that's really not correct and I'm just gonna leave it at that lol.
Do you have any long term experience Alternativista using a Vitamin D supplement? How'd it work for you?
And yes greatsite18, thanks for the info. For me though, I have very little acne but just extremely oily skin. Good to hear it's working for you though. How long have you been taking it?
My comments about D were in direct response to your comment about why derms don't prescribe it. And I said nothing about their ability to diagnose anything. I was talking about how they choose to address and 'prevent' health issues.
My comments about cholesterol is correct. There's one kind. HDL and LDL are lipoproteins that carry cholesterol around so it can do its very vital functions. And neither one of them are bad. Having the wrong ratio of LDL to HDL can be a sign of a problem, but that doesn't mean LDL is the culprit.
Also, being an athlete or gym rat doesn't = healthy. It's very damaging. Healthy exercise doesn't involve gyms.
My skin cleared with my diet changes so if you are asking about any experience with D and acne, I can't tell you. But I don't think it has that much affect on oily skin. It's mostly about skin function, cell turnover, etc.
Of course it is the carriers that give the different cholesterol forms its name. Chemically, yes there is one compound to which we have given the name "cholesterol," but inside our body it is very rarely without those lipoprotein carriers. It only make sense for doctors to tell you there are two "kinds" of cholesterol, because depending on the carrier they have significant differences in characteristics. If your doctor gave you your total cholesterol number as a single metric, it'd be pretty useless wouldn't it? In this sense there are two kinds of cholesterol.
Do you have any scientific studies showing that LDL is not bad for you? I am genuinely curious. Saying that neither kind of cholesterol is bad is directly contradicting to much of the scientific information out there.
And as for your comments on exercise, I'm sorry but that is simply laughable. That's one of the problems with people today, no one wants to exert any energy and then they wonder why they are overweight, can't sleep at night, have high blood pressure, blah blah blah.... the list goes on and on. Of course it doesn't have to be in a gym, but for most people that is they only way they have access to the equipment needed for what they want to do. Running is great, don't get me wrong. But at some point light weight training or body weight work is beneficial for everybody and does things endurance exercises can't.
It's only damaging if you do it wrong by the way, which unfortunately most people end up doing before they learn the right way. But saying healthy exercise doesn't involve gyms is just ridiculous. If you were to give health screenings to a large sample of those that go to the gym and those who don't, accounting for factors such as age and sex, I hope you realize which group would have overall healthier numbers.
And I have no interest in derailing this Vitamin D thread, so this is the last I'll be debating off topic Alternativista.
