Vitamins can increase risk of death?

You may have seen various news reports today about a Danish study on antioxidants. Headlines state things like Vitamins may increase risk of death – study. Well, I've obtained a copy of the actual study. It was a meta-analysis, meaning it reviewed lots of other studies and tried to do an overall analysis. The researchers' conclusion? 

Treatment with beta carotene, vitamin A, and vitamin E may increase mortality. The potential roles of vitamin C and selenium on mortality need further study.

The study is titled Mortality in Randomized Trials of Antioxidant Supplements for Primary and Secondary Prevention: Systematic Review and Meta-analysis by Bjelakovic et.al. (27) and published in the February issue of JAMA – the Journal of the American Medical Association

Now, let me say upfront I'm not a fan of this type of study. Meta-analysis can easily be confounded by the different types of studies included. For example, two-thirds of the studies included in the Bjelakovic paper involved people with heart disease, cancer or other risks who were being treated to see if the supplements helped. In other words, they were being used to see if vitamins, and in particular anti-oxidants, were an effective treatment - not whether they had a preventative effect. It's already been fairly well established that, for example, beta-carotene has a negative effective on mortality of smokers. There's even been a possible mechanism for this established. Treatment studies are not necessarily applicable to prevention. The studies also covered an enormous range of dosage. The Vitamin A studies included had dosages ranging from 1333 to 2 IU (American RDA for adult males is around 3IU/day). Some studies also gave mutliple supplements, some gave single supplements. All in all, in my opinion, the extreme lack of homogeneity raises questions about the validity of a meta-analysis approach.

Having said all of that, there is one section at the end of the study that is of interest to Nutrilite and Nutriway users and Quixtar and Amway IBOs –

Because we examined only the influence of synthetic antioxidants, our findings should not be translated to potential affects of fruits and vegetables.

One of the key features of Nutrilite and Nutriway products is the use of plant concentrates rather than synthetics. When the science supports it, some synthetics are used to boost levels of particular nutrients, but the key ingredients come not out of a chemistry laboratory but from fruits and vegetables. That's the Nutrilite Difference and probably one of the reasons why Nutrilite keeps topping consumer satisfaction surveys.

  2. Hello, Are there any side effects to amway’s nutrilite hair, skin and nails vitamin? And is it FDA approved?

    1. Why would it need FDA approval?
      Checking the ingredients it doesn’t appear to have any that commonly have negative side effects, though of course each individual is different. I met someone today allergic to lemons!

  3. I just found out I am pregnant. Only 6 six weeks so far. I’ve been taking Double X vitamin supplement for a few months and always feel great from it. Is it safe for my baby? My doctor has prescribed folic acid. Is it safe to take both?

    1. Indian people eat most nutrition food compared to other countries so please do not take anything faltu like nutrilite…..

      1. From UNICEF
        In India 20 per cent of children under five years of age suffer from wasting due to acute undernutrition. More than one third of the world’s children who are wasted live in India.
        Forty three per cent of Indian children under five years are underweight and 48 per cent (i.e. 61 million children) are stunted due to chronic undernutrition, India accounts for more than 3 out of every 10 stunted children in the world.

        From Rao, Shobha (2001), Nutritional status of the Indian population

        it is necessary to discuss some strategies required for improving the nutritional status of our people

  5. I have been taken positrim to lose my weight in healthy way…I’m still walking, do some exercise and take regular meal ( example take breakfast+positrim, lunch+no positrim, bread + poistrim for dinner)
    My weight is 60kg..ideal weight is 50-55kg

    a) i there any side effects of positrim?
    b) I’m intended to take Nutrilite BIo-C for skincare prob and multivitamin for extra energy…is it ok due to medical perspective?

    1. Hi,

      Better avoid breakfast, take alone positrim for 15 days and same way stop eating bread and take positrim for 15 days. Then after that , take positrim only once a day for 2 and half months. You will find the better results.
      Yes it is fine to Bio C, as it helps in many ways and ok to take multivitamin

    2. Please regularise the intake by like this . Take positrim in two halfs with one hour interval of one pack content in the morning avoiding breakfast. have normal lunch. and light dinner preferably chapaties or roti. do normal exercises what you r doing now. my weight has come down by about 10 kgs without any fatigue. sangeetha

  6. I am very lean,(age 22) so i want to use Amway products to build some body… is it safe to take or any side effects??

    1. Amway products are generally very safe when used according to instructions, but with anything there’s always a risk of allergic reactions in a very small percentage of people.

  7. Dear Sir,

    I used to take Amway Products like Nutrilite & Cal Mag D. After about 2 years of its intake, I stopped it about 7 months back. Now I am suffering from Osteoporosis. I am 41 years of age. My doctor has again asked me to continue these products as supplements. I wonder whether these are addictive.

    1. Well, feeling healthy can certainly be psychological addictive. If you mean physically addictive – well their essential nutrients, your body needs them. These nutrilite products are based on real food, so they’re “addictive” they same way food is.

      But not the way illegal drugs are, no.

  8. I’m taking Amway Nutralites products from last one and half months (like Cal Mag, Ginseng, Parsenelium,F & V, Daily, Protien,Salmon Omega). But after one week of taking these supplements my stool/faeces colors changes to brownish black and still same problem I’m facing. I went for stool routine test and also occult blood tests but all reports are normal. I want to ask anyone who knows about this and it it is a positive sign or a negative one?

  9. I have started Double-X a week ago. And I found that I often feel dizzy and headache. I feel strange taking it but I didn’t notice much on the energy level. Maybe because I got so dizzy and my head getting heavy all day. Not sure if this something to do with my med (Zoloft-antidepressant)?.

  10. If you have any side effects with Double X, I suggest lower the dosage. I only have quarter of what they recommend plus two tablets of CalciumMagD and I feel so healthy and great. My energy level is excellent. All the body pain and the joint/arm pains I have been having for several years have all gone. If you can add healthy diet plus the exercise, you’ll feel the result. For children’s brain, amway has Omega DHA that’s so great for brain development weather for children, adults or for elderly who have mental disorders, i.e. alzhimer’s disease.

  11. Hi, can you give me an advice of what Amway vitamins/supplement can I give to my son to boost up his IQ,so that he can concentrate more to his study in school.

    Thanks.

    1. If only it were so simple! Have your son take a blood test to see if he’s low in any of the basic vitamins and minerals. Low levels of many of them, including iron or B-vitamins, can contribute to concentration problems. The first step to fixing problems is always to look at his diet. How is his intake of fruit & vegetables? How about oily fish? Lack of omega-3 – or too much omega-6 – has been linked to concentration problems.

      Consider issues like that and address dietary and lifestyle issues. Supplementing with something like Daily or Double X, along with Omega-3, may also help.

      Be aware nutritional issues can take months to improve though.

  12. hi i purchased attitude whitening cream with toner and cleanser…. is that product good or will it cause any side effects…. waiting for a quick reply…. someone help me out…

    1. Artistry is a world-reknowned brand and does extensive testing on their products, but it’s impossible to claim there’ll never be any side effects with any individual. Some people are allergic to all sorts of otherwise common and harmless ingredients.

  13. I just started taking these Amway multivitamin and feel wierd, lightheaded after about 15-30 min of taking them. Is this normal? I paid for them so im kind of disappointed. Thanks

    1. I’ve never heard of that before. Bit hard to know what it might be without more info, such as which product it is. Could be anything from placebo to niacin flush and anything in between.

    2. I also felt some side effects inlcuding insomnia and icreased heart beat. I tested it two three times and everytime felt the same. After stopping it;s fine. All these products are made in india and the amway executive promotes them by saying they are made in US.

      1. some of the promoters may be confused you. amway never tells it is made in usa. it is made in india.and now in tamilnadu amway itself building the self plant.

  14. Can pregnant ladies have Bio C ( Amway product)? my wife has severe cold and she is 5month preg carrying twins. So everytime she sneezes, pressure is on stomach. I want to know if she can have the Bio C. any side effects on babies inside?

    Quick reply will sincerely be appreciated.

  15. Dear Sir,
    I need your explanation on the following:

    1. What is Amway multivitamin (Nutrilite) or any other vitamins?
    2. Do you have side effects for taking any Amway products?

    Thanks.

    1. The “Amway vitamins” you’re asking about is Nutrilite Double X, the number one multivitamin on the market. As you’ve seej in previous posts, it is not made from synthetics, but from plant concentrates. Double X contains over 33 vitamins, minerals, and phytonutrients.

  16. I have been taking Amway vitamins for years. Today I need to know on Vitamin E what 30UI,means? What is the mg’s on this? I have a medical reason for asking.
    Thanks,
    Edna
