  1. Hi,

    I've just began supplementing 400ug of Chromium a day, after having it
    recommended to me following a hair mineral test. About an hour after
    taking it I start to feel so tired that I am useless, start slurring
    words, and generally feel wasted. It seems that chromium is giving me
    hypoglycemia, but I have heard from many sources that it's supposed to
    help with hypo. Does anyone have any experience with this? Maybe it's
    a temporary thing?

    Tony.

  2. There are different forms, and the other ingredients in the supplement
    could be the problem. You could reduce the dosage, try different brand
    and different forms, and there's nutritional yeast, which is high in
    chromium. I eat small amounts of nutritional yeast with each meal,
    less than a teaspoon, but I don't take chromiumc supplements. You
    didn't say why you are taking it. Trace minerals are undeniably
    important, but if you are deficient, it is important to discover why.
    If there is a great deal of oxidative stress, some minerals might be
    getting used up by the SOD activity, for example. Aside from a
    "balanced diet," one needs to avoid more than small amounts of
    oxidative (and other forms of) stress. Get to the underlying or root
    cause - otherwise, there's going to be a major problem at some point in
    the not too distant future. Most problems in countries like the USA
    are the result of too much arachidonic acid stored up in the tissues
    (which can then be turned into very dangerous metabolites upon minor
    stressors) and too much dietary oxidative stress (lipid peroxidation),
    which is enhanced by high iron diets and low antioxidant diets.

    I'd give you more specific suggestions if you were more specific (age,
    gender, height/weight, previous medical history, your diet, etc.).

  3. Thanks for your response Montygram, I'll chew over what youv'e said.

    The chromium I am taking is Chromium Picolinate, I was also low in
    copper and told to take that also, but am only taking the chromium at
    the moment as I'm waiting for my liquid copper to arrive in the post.
    The interesting thing about the effect the chromium is having on me, is
    it's exactly the same as what happened when I was taking magnesium a
    few months back. After 3 weeks on the magnesium my appetite went
    through the roof and, I began feeling woozy and a bit out of it. The
    nice thing about it was all the extra food I was eating was going on as
    muscle, with no training. I was tempted to keep on with the magnesium
    as I really appreciated the way it was changing my bod, but I was half
    zombie and had to give it up. From what I have read both the Mag and
    the Chromium increase insulin sensitivity, so maybe this is what has
    been happening with both, the increased insulin sensitivity is pushing
    more glucose into muscle and leaving the blood level too low for normal
    functioning. Maybe it is at this point that the copper deficiency
    comes in, as I know this mineral is needed for Epinephrine synthesis,
    which would rescue my low blood sugar. But is in too short supply to
    get me back on an even keel. What do you guys think?

    Oh and Montygram, here's my specs:
    Age 28
    Male
    Height 70 inches
    weight 170 pounds
    Medical hist: ongoing fatigue, allergies, cold hands and feet
    Diet: Mixed meat eating diet, mainly fish protein, also eat a wide
    range of fruit and veg, avoid grains.

    Thanks for offering more suggestions, I'd be very happy to hear what
    you think.

    Tony.

  4. When I began to overcome severe osteoporosis (no, I'm not an old lady,
    but a thin, 40 year old male), I went through a period when I had
    almost a pregnant woman's appetite.

    There could be all kinds of things going on. You could even have
    Charcot Marie Tooth (cold hands and feet). If you can get a doctor to
    do all kinds of tests, then you'll get a better idea. Thyroid
    suppression is good possibility. Have them do a test for parasites
    (stool test), as well as comprehensive blood tests, urine test, and
    anything else you can get. If they detect something, you can send me a
    message and I'll give you my ideas. Some claim that too much zinc
    means allergies and auto-immune problems, whereas too much copper means
    a depressed immune system. You could have something like orthostatic
    hypotension. You can just take your BP and heart rate after lying down
    for 20 minutes or more, then do it again after walking around for ten
    minutes (just walk slowly, and stand still for about half the time,
    alternating - just as you would if you were making dinner or something
    like that). If BP and heart rate change (BP going down as heart rate
    goes up), that can cause a "chronic fatigue syndrome" by itself).

    Even though it was probably way overblown, there was a study done I
    think on mice that showed (I think, but could be wrong) Chromium
    Picolinate caused DNA damage in the mice.

    I could be wrong, but look for study if you want...and make up your own
    mind... search for it on google if you want..

    getting "used up" by the SOD actitity?
    you are aware that chemical elements do not have the habbit of spontaneusly
    disappearing or transforming into other chemical elements.. don't you?

    No, chromium helps to stabilize your insulin levels - if you are
    'insulin sensitive' it it doesnt increase it, it helps prevent it. You
    might get more info/tips here: http://tinyurl.com/4u2yz

    I would be looking at WHAT you eat after taking your supplements and
    thruout the day and make some changes because I dont think its the
    supplements, but more what you are eating or not eating that is causing
    your 'symtoms'. My question is, why arent you getting some of these
    necessary minerals from their food sources? Usually supplementation is
    just that 'in addition to' not in lieu of, if you know what I mean. I
    could see if you had been eating lots of foods that contain these trace
    minerals and still were depleted, you could need supplementation of
    them to bring your levels up to par - but then the question would be
    WHY are you deficient in these? I would look deeper into this before
    just taking whatever - liquid copper? Do you have digestion problems or
    chrohns disease? Otherwise copper deficiency is extremely rare:
    http://tinyurl.com/bhpsj

    Magnesium, as one of its uses, may help in energy metabolism - its
    needed by certain enzymes to help convert foods thru digestion into
    energy. Really nothing to do with insulin. Read more about magnesiums
    uses here: http://tinyurl.com/de8yx

    Oh and btw for the person that mentioned about chromium damaging DNA
    there's info about that as well in the first link - a few mice tests
    with wopping overdose amounts doesnt always translate into humans.

  10. High iron diets are the most common problem. Nobody is suggesting that
    one consume large amounts of lead, etc.

    The SOD issue is interesting. Several studies have found that people
    who live the longest have the lowest SOD activity, but high vitamin E
    levels, whereas the reverse is true of those who are middle aged and
    dying or who have "chronic disease." The body can crank up SOD levels,
    but certain trace minerals are needed, and if they are being used for
    that purpose, they can't be used for other vital purposes, unless one
    is getting much larger amounts than most people.

  11. You can find several CMT web sites that will give you all the info. you
    want. The nerves in the hands and feet die off, then the muscles
    atrophy, etc.

    Not lead but other metals with a redox potential.. zinc for example-
    since the "the more the better" supplementation philosophy is so popular
    people are not aware that trace elements are supposed to be exactly that..
    taken in trace ammounts.

    iron is a problem because the span between too low and too high iron levels
    is so small. generally however iron problems (like lipid peroxidation etc)
    can only occur when there is iron overload and the iron binding protein
    system (ferritin/transferrin) is overpowered. only _free_ iron is a problem
    in vivo.

    citation for the first part?

    small SOD activity is not the same as small SOD protein levels.
    you suggest that there is chromium deficiency.. but where is the proof?
    if there would be deficiency, what about glucose tolerance factor (another
    chromium dependent enzyme)?

  13. Quoted message said:

    The thing about chromium deciciency is total nonsense. It comes from people
    who want to sell you chromium supplements.

    I'm sure you are right that the people who sell the stuff are pushing
    the deficiency angle. But how can you be so sure that the deficiency
    isn't widespread enough to be an issue? After hearing about the
    importance of Chromium as a trace mineral I looked at my diet to see
    what high chromium foods I was eating. The only decent one was egg
    yoke, and you need about 100g of yoke to get the 200ug advised intake,
    that's about 6 or more eggs a day, there's no way I'm gonna manage that
    every day, talk about egg-bound!! Also seeing as I am definately
    experiencing a physiological response from the Chromium, and it appears
    that it's through blood sugar, I think it's safe to say I must have had
    some kind of deficit otherwise I wouldn't be experiencing a lowering of
    blood sugar?

    Tony.

  14. I'm not saying chromium is deficient due to SOD levels. Magnesium,
    manganese, selenium, zinc, and copper are the ones to be concerned
    about in this context. Chromium seems to help in certain conditions,
    but I'd just go with the nutritional yeast in small amounts with each
    meal.

    Plasma antioxidants and longevity: a study on healthy centenarians.

    A large body of experimental research indicates that oxidative stress
    contributes to the processes related to aging and to the pathogenesis
    of several age-related diseases. Vitamins and antioxidant enzymes have
    a fundamental role in defending the organism from oxidative stress. To
    better understand the role of antioxidants in human aging, we measured
    plasma levels of vitamin C (ascorbic acid), uric acid, vitamin E
    (alpha-tocopherol), vitamin A (retinol), carotenoids, total thiol
    groups, and the activity of plasma superoxide dismutase (SOD) and
    glutathione peroxidase (GPX) as well as the activity of red blood cell
    (RBC) SOD in 32 healthy centenarians-17 elderly subjects aged 80-99
    years, 34 elderly subjects aged 60-79 years, and 24 adults aged less
    than 60 years. Considering the "noncentenarians" only, we observed a
    consistent behavior in the antioxidant pattern, with a decrease of the
    nonenzymatic antioxidants and an increase of the enzymatic antioxidant
    activities relative to age. Remarkably, centenarians were characterized
    as having the highest levels of vitamins A and E, whereas the
    activities of both plasma and RBC SOD, which increase with age,
    decreased in centenarians. From these results, it is evident that
    healthy centenarians show a particular profile in which high levels of
    vitamin A and vitamin E seem to be important in guaranteeing their
    extreme longevity.

    Did you read the paper?
    This was the composition of the groups:

    young adults: (>60 yrs)
    13 women 11 men (makes roughly 50:50)

    young-old subjects: (61-80yrs)
    13 women 13 men (50:50)

    old subjects: (81-99yrs)
    7 women 10 men (roughly 50:50 again)

    the last group, the one they used to make their statement has a totally
    different composition

    cenetarians test group: (>100yrs)
    25 women and * 7 * men (makes almost 80:20%)!

    its well known that women differ greatly from men when it comes to age
    related studies..
    having the one group you'd like to say something about being so radically
    [no pun intended] different from the rest is at best very dubious.

    not to say that high retinol and high tocopherol levels don't play a very
    important role.. but this study certainly does not have the power to say so
    because the test group composition is majorly flawed compared to the
    others.. and I hope you will at least agree on that bit.

  16. I am really getting tired of refuting people like MMu and MattLB with
    actual scientific evidence. They, on the other hand, enjoy attacking
    my obvious typographical errors. If you listen to these guys, your
    health may be at serious risk. MattLB recently attacked what I said
    about tightly wound DNA an cancer cells, yet it was on sciencedaily.com
    a few weeks back. DO SOME RESEARCH - AND CITE SOME RESEARCH, rather
    than making ludicrous, non-scientific attacks. As for the lead claim,
    here is the evidence. I'm not sure what planet MMu is on, but the
    problems that lead causes in the body are well-known and free radical
    mediated. How much evidence do I have to post here? The worst attacks
    are from those who say that with oxygen, one can't live, therefore
    worrying about free radicals makes no sense. However, what I am
    talking about are processes like in vivo lipid peroxidation (which is
    fats going rancid in your body) or chronic inflammation, which
    generates free radicals in large amounts and damages tissue and organs.
    This has nothing to do with mitochondrial respiration, which indeed
    should be optimal, not reduced in any way, but these people need red
    herrings to justify their moronic claims.
    Here's a refutation to MMu's claims about the effects of lead:

    Recent studies have shown that lead causes oxidative stress by inducing
    the generation of reactive oxygen species (ROS) and reducing the
    antioxidant defense system of cells. This suggests that antioxidants
    may play an important role in the treatment of lead poisoning as a kind
    of excellent scavenger of free radicals and chelator of heavy metal.
    Whether tea catechins have protective effects against oxidative stress
    after lead treatment in cell systems remains unclear. The present study
    was designed to elucidate if tea catechins have any protective effects
    on lipid peroxidation damage in lead-exposed HepG2 cells. Exposure of
    HepG2 cells to Pb++ decreased cell viability and stimulated lipid
    peroxidation of cell membranes as measured by the thioburbituric acid
    reaction. Electron spin resonance (ESR) spin-labeling studies indicated
    that lead exposure could decrease the fluidity in the polar surface of
    cell membranes. Tea catechin treatment significantly increased cell
    viability, decreased lipid peroxidation levels, and protected cell
    membrane fluidity in lead-exposed HepG2 cells in a
    concentration-dependent manner. The galloylated catechins showed a
    stronger effect than nongalloylated catechins. Cotreatment with
    (-)-epigallocatechin gallate (EGCG) and (-)-epicatechin (EC),
    (-)-epicatechin gallate (ECG), and (-)-epigallocatechin gallate (EGCG)
    showed a synergistically protective effect. The results suggest that
    tea catechin supplementation may have a role to play in modulating
    oxidative stress in lead-exposed HepG2 cells.

    Just remeber one thing: free radical DAMAGE is the key to "chronic

    Here's a refutation to MMu's claims about the effects of lead:
    ....

    claims about lead?
    I am slowly very concerned about you answering and fighting back claims that
    nobody took..
    this actually could be a lack of n3 fatty acids in the cerebrum.

    lets take this slowly.. shall we?

    you said:

    High iron diets are the most common problem. Nobody is suggesting that
    one consume large amounts of lead, etc.

    I answered:
    "Not lead but other metals with a redox potential.. zinc for example-
    since the "the more the better" supplementation philosophy is so popular
    people are not aware that trace elements are supposed to be exactly that..
    taken in trace ammounts."

    even simpler:
    you: "nobody is suggesting that one consume large ammounts of lead" _ i:
    "Not lead but other metals with a redox potential.. zinc for example".

    I will even spell it out for you:
    people are not suggesting lead but are suggesting that one consume large
    ammounts of other metals with a redox potential like zinc which might be a
    problem when it comes to free radical damage.

    Just remeber one thing: free radical DAMAGE is the key to "chronic


    disease," and if you search on pubmed.com you'll find many researcher
    saying this explicitly.<<

    COMMENT:

    They can say it as explicitly as they want, and that doesn't make it
    generally true. It's a theory that goes back to Harman and has been
    promoted by optomists like Pearson and Shaw, and has gained currency as
    a good hypothesis. The problem is that there's not much evidence for
    it.

    Now wait, you say. Whenever there's worn out or damaged tissue, aren't
    there more free radicals around? Sure. Whenever there's damage to
    buildings by fire or crime, there are lots of cops and firemen around.
    This does not mean that uniformed people or paperwork or insurance
    claims cause disasters. Try *removing* the cops and firemen to test
    this hypothesis. It doesn't work.

    Nor does removing free radicals modify chronic disease progression,
    much. The biggest cause of chronic disease in developed countries is
    aging. If you remove free radicals by introducing spin traps,
    antioxidants, and so on, you do not find aging markedly changed in
    animals. There were some hopeful experiments along that line, but they
    haven't been replicated, and some of the early ones turned out to be
    due to dietary restriction, not antioxidants (these things often taste
    bad). Nor is there much evidence that you can modify the rate of
    "chronic disease" in humans by giving antioxidants. I've brought up the
    subjec of vitamin E, and all the proponents can think of to say is that
    maybe we have to use every kind of molecule with vitamin E activity
    that exists in nature. Well, they didn't say that 25 years ago before
    the vitamin E experiments failed. The claims of the vitamin hawkers are
    moving targets. Produce data against them, and they just change. They
    are not only data-free, but data-proof. When it's explained to these
    people that the greatest life expectancies and lowest chronic disease
    rates occur in the Japanese, who probably eat one of the highest
    polyunsaturated fat diets there is, they just blank out and invent
    magical reasons that the Japanese might be eating huge doses of free
    radical blockers to make up for it.

    You wouldn't want to just damp out all free radicals [censored] nilly
    anyway, even if you could. They are the body's messengers for dealing
    with infection, and for triggering healing. Yes, sometimes they need
    modulation. Free radicals are produced in copious amounts during tissue
    damage (acute trauma or infection or tissue ischemia) and they often
    are produced in amounts too large for optimal health (due to the fact
    that evolution did not design you with antibiotics in mind, nor to
    survive giant traumas that require ventilators and pressor support or a
    lot of brain or heart ischemia--- you're expected to DIE in those
    cases). So antioxidants (ironically) actually shine more as possible
    modifiers of ACUTE disease processes, not chronic ones. For chronic
    disease, the inflammatory process will probably need to be modified far
    higher up in the process than the end-result where free-radicals are
    generated. Another story.
