The supplements industry is basically snake-oil so far as I can tell. Unless you have a known deficiency, or a horrifically unbalanced diet, as far as anyone can tell they're a waste of time and money.

"... so far as I can tell."

Look - anyone of us can just spout our opinion. What separates HN is that people take the time to explain their reasons and often credentials. If you said, "Here's why and BTW I've worked in this industry as an XYZ for 25 years" - your opinion might matter. But as stated you've just stated your own personal opinion as though it is fact. Downvoted for that reason.

You must be thinking of HN from a few years back, it's basically just a discussion site these days AFAICT.

My opinion wasn't on the supplements by the way, it's on the industry. The industry which in Europe has to include disclaimers in all its advertising to the effect of "this stuff might be useful for the elderly and those on restricted diets" because there's no evidence for anything. The industry which heavily resists any effort to regulate it various medical claims in the same way actual medicines are regulated. It's shady as hell.

I assumed this was common knowledge.

Diet issues are one of those things that are really easy to miss. You can easily get used to feeling a little worse every day until significant issues sneak up on you. With that in mind a basic multivitamin is a cheap option.

You don't need to taken them every day, one multi vitamin ever other day or even one day a week can actually help with a lot of issues over the long term. Much like exercise consistency is more important than a few years of excess.

PS: I have actually been referred to a nutritionist due to medical issues.

So basically... vitamin D and probably not much else.
Re:Nutrition: Vitamins on trial by Nursie on Thursday July 03, 2014 @04:37AM (#7982089)
If you have a known deficiency, sure, but a quick web search will show you that it's arguable what level is deficient, and that it's arguable that supplementation has a good effect on anyone that's not suffering from a few specific conditions.

So I'll repeat - unless you have a known deficiency or a restricted diet, they're a waste of time and money, and the industry is snake-oil.

While I agree, at least for Vit. D, the issue is what is considered 'deficiency' is quite low by doctors/blood tests. I don't remember the values, but even doctors that a few years ago laughed (yes, laughed) on my wife and mine face because we we concerned about it and the effects of low Vit. D in her pregnancy are now recommending to their patients some supplementation even for known normal levels. (One doctor told us the only concern for low Vit. D levels were for the +65 year olds for example)

But real clinical evidence is still pretty shaky at best. Like 5 years ago there was a lot of hype about Vitamin D and a lot of hope that new studies would conclusively show value in supplementation, but it didn't turn out that way, e.g. http://www.medscape.com/viewarticle/819670
Re:Nutrition: Vitamins on trial by icelancer on Thursday July 03, 2014 @05:06AM (#7982153)
It is also dependent on your profession and location. If you are a collegiate or professional athlete living in the Northern US where sunlight exposure is generally bad for 6 months out of the year, then while your Vit D levels may just be below-average (but nothing major for a normal human), this could be a real issue regarding athletic performance.

Supplementation and testing must always be taken in context. The average sedentary human does not have the same caloric needs as the aspiring professional athlete, nor do they have similar supplementation needs either.

Re:Nutrition: Vitamins on trial by BSousa on Thursday July 03, 2014 @06:28AM (#7982300)
I fully agree. Athletes, pregnancy, high-stress jobs, depression, etc. Each have different concerns and specific nutrition focusing on them can be quite efficient at mitigating symptoms/improving results. Also location as you mentioned and genetics as well can influence the requirements of certain nutrients.

This

I don't remember the exact numbers, but if the sun is out there, around 10min (or maybe up to 30min) under the sun with light clothing will give you the needed Vitamin D dosage.

Now, in high latitude winter, the time needed is in the order of hours. With heavier clothing this becomes much harder.

Re:Nutrition: Vitamins on trial by vanderZwan on Thursday July 03, 2014 @05:12AM (#7982161)
My parents are general practicioners, and for the last few years they have basically been told that the rule of thumb is to assume everyone is vitamin D deficient until proven otherwise (where "works outside in the sun all day" is an example of proven otherwise).
Re:Nutrition: Vitamins on trial by streptomycin on Thursday July 03, 2014 @10:01AM (#7983096)
That doesn't mean that they have evidence that supplementation would actually help people. The currently available data says it could help, could do nothing, and could harm: http://www.medscape.com/viewarticle/819670
Re:Nutrition: Vitamins on trial by eitally on Thursday July 03, 2014 @07:32AM (#7982457)
I have regularly read that all it takes is 15-30 minutes of direct sun exposure per day to generate the RDA of vitamin D. Is that inaccurate (as someone who slathers his kids with sunscreen I would really like to know)?
Re:Nutrition: Vitamins on trial by fizgig on Thursday July 03, 2014 @09:11AM (#7982814)
Here's a nifty calculator that tells you vitamin D values for exposure times taking season and latitude into account.

Re:Nutrition: Vitamins on trial by vanderZwan on Thursday July 03, 2014 @07:49AM (#7982497)
I don't know the answer to that. However, assuming you are correct, I live in a country where direct sun exposure is a rare commodity even in summer, so the recommendation to my parents could still make sense then.

>>or a horrifically unbalanced diet

Heh, have you seen the average US citizen's diet? I think a significant percentage of diets among USA inhabitants can be called "horrific" without being an exaggeration.

We have stuff like this happening... http://www.heartattackgrill.com/heart-attack-grill.html

"Over 350lbs? Eat for Free!!!" ---Seriously, that's a policy of this business.

Re:Nutrition: Vitamins on trial by arrrg on Thursday July 03, 2014 @09:18AM (#7982861)
So, I mean, the food on there is probably not the healthiest (the unhealthiest thing about it are probably the portion sizes, though, not anything it contains) and it might be a bit unbalanced from a macronutrient point of view (though I’m not even sure about that, maybe it’s a bit low on proteins and a bit high on fats, also, including the sodas it’s certainly high on sugar and very probably also high on salt) but I’m not sure you would end up with any deficiencies by eating that stuff. Meat, cheese, vegetables, bread. It’s all in there. The vegetable part is a bit small, but that’s about it.

In terms of variety burgers really aren’t that bad. It would be much more concerned about getting too much of something, not too little.
