    I have recently started taking vitamins and I've been taking them every other day... Should I be taking them everyday or is this ok?

    it depends what vitamins you are taking, what your diet is like, and what your nutritional needs are

    some personal recommendations-

    don't use multivitamins, instead buy individual vitamins.

    Multivitamins are a gimmick. They are full of huge volumes of the cheap vitamins, but are often completely lacking in the hard to get ones.

    multivitamins often have disproportionate levels of B vitamins, and usually lack one or two of the B vitamin complex. This is disasterous because the body gets rid of all B vitamins equally when there is an excess of one. Taking B vitamins in disproportionate amounts will cause deficiency.

    Too much unused calcium will give you kidney stones

    if you are taking calcium make sure that you are also getting vitamin D(or getting plenty of sun) and magnesium(bananas are my favorite source)

    too much of many nutrients can be bad, but a few of them are not

    vitamin A, C, D and E, to the best of my knowledge, have no negative characteristics

    K will help your blood clot, so if you are at risk of heart disease be a little cautious, but if you are anemic - have at.

    so again, I recommend buying individual vitamins, and avoiding multivitamins. Some things are good to combine, like your B vitamin complex, try to find one that has ALL the B vitamins, in proportionate levels. Another pill that has calcium, magnesium and d is handy. Another pill that covers your electrolytes and iron is also handy, but make sure your not getting insane levels of things.

    I like to cut my vitamins in half, and instead of taking them once or twice a day, I'll take half as much twice as often.

    There is a lot to learn, and lots of opinions to avoid(take for example mine)

    not true and which are the hard ones to get that you're thinking of? It is hard to overdose on B vitamins, so there is little harm in taking too much.

    vitamin A, C, D and E, to the best of my knowledge, have no negative characteristics
    Wrong, vitamin A in large doses raises liver enzymes and causes liver injury, it can very rarely cause cirrhosis. This is relevant when treating people with bad acne vulgaris with vitamin a cream. Their liver blood tests must be monitored to check for liver injury from the treatment.

    K will help your blood clot, so if you are at risk of heart disease be a little cautious, but if you are anemic - have at.
    That is poor advice, ignore that. It would only be relevant if you were put on anticoagulant therapy such as warfarin or had a genetic clotting defect.

    I always believe that a well-balanced food comprising fish, bread, rice, vegetables + fruits in variety should be more than enough to provide all the nutrients. Vitamins are just supplement and not necessarily need to be taken unless under special circumstances when maybe you are sick, under job stress or recovering from sickness. Even then I only concentrate on vitamin C.
    Life can only be meaningful if you have the luxury to do what you love to do most.

    Yes you can use vitamins every day (about 30 days period and then have a about 1-2 months pause) if you choose natural vitamins complex with all vitamins and mineral material recommended standard of the day)
    And choose vitamins in that period of the year when you have not well-balanced food. Specially in winter when you get less vitamins from food. Or when you feel tired and so on.
    I choose the type of vitamins where is all needed vitamins and mineral materials. and feel much better. :wink:

    And additionally has been linked to increased rates of birth defects. Cardiac abnormalities if I am not mistaken.

    Far as I know, the jury is very much out on whether there's any significant benefit (or harm) to regular consumption of vitamins for healthy people. If you have a specific vitamin deficiency, then there's an obvious need for supplementation. But this is something that you'd need to have diagnosed by a GP (don't assume because you're "run down" that this is something that you need to fix with pills). There's also a well documented benefit to folic acid for pregnant women, but that's hardly applicable to most people, most of the time.

    That's about it for the definite benefits. I have heard that the AMA officially recommend some supplementation, but as far as I know they're amongst the few such associations who feel confident to do so. Studies looking at cold and flu resolution with Vit C supplementation show basically no benefit. Some studies have even shown marginal decreases in lifespan with a fairly normal dose of your average mix of antioxidants. I think the Cochrane Library has some meta analyses on that. But otherwise a balanced diet with fresh food should remove all need for daily supplementation regardless of the season.

    The concept that our food contains less vitamins than it "used to" is a bit hokie I think. I've never seen an actual study that demonstrates this to be true, though I'd happily read one if anyone has a link. I won't be reading any dodgy natural/organic propaganda websites though. Something peer reviewed.

    I agree that multivitamins perk me up when I remember to take them.

    Does anyone else have data on MV being cheap ass products?

    Every pregnant woman should be taking folic acid, it's required for DNA replication and a minor deficiency causes serious birth defects. There has been a marked decrease in the amount of birth defects in Canada since the government mandated the addition of folic acid to all cereal products.

    Perhaps I was unclear- by not being applicable to everyone most of the time, I was referring to the non-pregnant. I'm aware of the importance of folic acid in neural tube development during pregnancy.

    Placebos perk people up too, so long as you don't tell them they're placebos.

    Varied diet, good fluid intake, minimise alcohol intake, get good regular sleep. There are no pills that have been convincingly shown to help study.

    One can become mentally unstable while traveling in the vast world of supplements. Upon adding up all the vitamins people will tell you that "you must have" you will easily find yourself consuming 50+ pills a day. Not to worry however, because as soon as you take away all those which might in time come to harm you, you will be left with none at all, because everything is harmful in some fashion. You're best bet is to find a good dieting guru, blindly ignore everyone else, and practice the golden rule of dieting and exercise, which is, namely, Consistency.

    Or you could use a quasi-mystical approach like I do. For example, doughnuts bought to support cancer awareness are beneficial to you, while fruits bought from countries that use children as soldiers are bad for you. "Good" and "Bad" are entirely placebo, because I'm nearing 200-pounds, most of it goodwill, little of it muscle.
    Begin at the beginning and go on till you come to the end; then stop.

    Well - Glucosamine supposedly is not proven to have any special effect.

    But I sure know it when I haven't been taking it for a few days!
    I would have to find the original study that was done.
    In the meantime, I'm gulping it down until I find proof that it is merely a 7-year long Placebo effect.
