Is it possible to digest too much vitamin and mineral ? I take a daily multi vitamin and usually eat a power bar and one or two energy drinks during the day. Not to mention vitamins from my food source. Each of these on their own meet or exceed the daily requirement. So can you intake too much of a good thing ?
I AM AWESOME MAN

Nomad, I cannot give exact specifics, but it seems there are some, like maybe A and D which are not good in massive quantities. I have heard that the super mega doses are not really as beneficial as people think, better to go with RDA.

I think you are getting plenty of vitamins and minerals.
You are better then me, I takes lots of vitamins and herbal ones daily. Since I'm a girl, I take extra calcium.

Don't forget the iron Chonsi....we need to suplement that, too.

That's true, I take a multi with iron, but the extra vitamins keep me healthy when around school kids during the year. I usually don't get sick, not for 2 years now.

Except for those of us who have too much iron, like my 3 daughters and me. Hemochromatosis. Iron overload.
Nomad, I know too much of some vitamins can counteract others and negate their benefits.

Oh, I never heard of that before. What are the negative side effects of too much iron?
Vitamins Minerals
People with too much iron are GREAT blood donors!!
;)
Marie's right about the vitamin A, but I think you'd have to be
an Eskimo and eating a lot of whale livers or something.
Chons, it's not best to take a multi with iron. Iron "fights" with A,
E, and calcium and you don't get good absorption of them. I
take all vitamins in the morning except my C (which HELPS with
iron absorption) and iron I take at night.
I'm not around kids but I can't remember the last time I even had
a cold, probably 5/6 years?
Relax Nomie you are fine. If your urine turns bright yellow you might
back off a little, but that's just your body's way of getting rid of
excess.

Actually they are not, Valerie. They won't let them donate. My daughters have regular phlebotomies and they throw the blood away.
Some of the adverse effects are storing the excess iron in other organs of the body. This can cause extreme fatigue, just like low iron. In my oldest daughter's case, she tested for morbidly high iron overload and they were afraid of liver damage. Fortunately they did a liver biopsy and had caught it in time to prevent that. The only cure or way to reduce it is by phlebotomy-taking a pint or so, at regular intervals. My oldest and youngest are afflicted. My middle daughter and I have it to a lesser degree. We have not had to have phlebotomies/

Your body will use what it can and will "pass along" what it can't hold.The more you exercise and the more active you are the more your body will use.So multi vitamin is the best chioce for all around with a little extra "c" for the risky times.

Interesting. I suspect it's a matter of degree or something. The ones
I heard told to donate probably didn't have as high as your daughters.

I'm sure you can have too much of a good thing - there's a lot of information "out
there (search engine) that suggests both good and bad effects from large doses
of vitamins. I'd tend to keep approximately to the RDA guidelines, with a weather
eye on the maximum recommended amounts.

Much the same can be said for the RDA for vitamin d. Totally lack of back up for the current recommendations. Anyone who sticks to the RDA for vitamin d will be vitamin d insufficient if not deficient.

It is possible to overdose on all vitamins, but only after a prolonged period. Vitamin C is hard to overdose on, but it is possible.
Taking too many vitamins once or twice does no harm as the body flushes out what it doesn't need. However, over a prolonged period, you can make yourself very ill.
Minerals can build up more quickly as the body generally only requires small amounts. Iron, however is required at the rate of 10mg/day for males and 12 - 15mg/day for females depending on their time of month. This is only a guide however as people differ. My body manufactures a lot of iron and iron supplements or iron from food go straight through me.
Other major minerals include calcium, phosphorus, magnesium, zinc, sodium, chloride and potassium. The rest are needed in trace amounts only and it has been impossible to establish the full complement of minerals required by the body.

I would recommend the Manual of Nutrition as a starting point for learning more on the subject. It is still available:

Why people feel the need to make authoritative statements on subjects that they are totally unqualified to do so is one of life's little mysteries that continues to elude me. The road to hell is often paved with the best of intent.
Unfortunately, in the world of alternative health in general, and supplements, specifically, you can't read about this stuff and understand it. The waters are too polluted. Most of what's written as science is nothing more than clever marketing. You have to establish a relationship with a teacher/coach/practitioner with both the expertise and moral center, who will tell you the truth, even when it isn't what you want to hear. And you can't go to your doctor. Not for this. Even the one's who purport to practice alternative medicine have been trained in a reductionist paradigm that renders them ill suited for this. The just don't have a feeling for how these compounds work. They're trained to identify symptoms and suppress them.

You certainly can get too much of a good thing where vitamin & mineral supplements are concerned. A,D & E are fat soluable vitamins which store in body fat. B complex & C are water soluable. The excess is excreted through the urine. It's chonic overdosing that can cause problems & of course the fat soluable vitamins are the ones you need to be especially careful of.
Nonspecific symptoms, such as nausea, vomiting, diarrhea, and rash, are common with any acute or chronic vitamin overdose. Vitamin-caused symptoms may be secondary to those associated with additives (eg, mannitol), colorings, or binders; these symptoms usually are not severe. The following are symptoms of specific vitamin overdose:
Vitamin A
Acute toxicity effects include headache, nausea, vomiting, drowsiness, and desquamation after 24 hours.
Chronic toxicity affects the skin, the mucous membranes, and the musculoskeletal and neurologic systems.
Skin and mucous membrane effects include erythema, eczema, pruritus, dry and cracked skin, angular cheilitis, conjunctivitis, palmar and plantar peeling, and alopecia.
Musculoskeletal effects include pain and tenderness, particularly in the long bones of the upper and lower extremities, which may be exacerbated by exercise; epiphyseal capping and premature epiphyseal closure may occur in children.
Neurologic effects include blurred vision and frontal headache, which is often the first sign of toxicity.
Findings also include papilledema, hepatomegaly, ascites, erythematous dermatitis, migratory arthritis, craniotabes in children, or bulging fontanelle in infants.
Recent studies suggest that elevated levels of vitamin A may cause increased bone resorption and promote development of osteoporosis.
Vitamin D
Acute toxicity effects may include muscle weakness, apathy, headache, anorexia, nausea, vomiting, and bone pain.
Chronic toxicity effects include the above symptoms and constipation, anorexia, polydipsia, polyuria, backache, hyperlipidemia, and hypercalcemia.
Findings may also include calcinosis, followed by hypertension and cardiac arrhythmias.
Vitamin E
Acute toxicity effects include nausea, headache, fatigue, easy bruising and bleeding (prolonged prothrombin time [PT] and activated partial thromboplastin time [aPTT]), inhibition of platelet aggregation, diplopia (at dosages as low as 300 IU), muscle weakness, and creatinuria.
Chronic toxicity effects include all of the above, suppression of other antioxidants, and increased risk of hemorrhagic stroke.
Vitamin K
This particular toxicity is typically associated with formula-fed infants or those receiving synthetic vitamin K-3 (menadione) injections. Because of its toxicity, menadione is no longer used for treatment of vitamin K deficiency.
Effects may include jaundice in newborns, hemolytic anemia, and hyperbilirubinemia.
Toxicity also blocks the effects of oral anticoagulants.
Vitamins B-1, B-2, B-12, and folate
Effects may be minimal and nonspecific.
Vitamin B-2 turns the urine yellow-orange.
Vitamin B-1 (ie, thiamine) toxicity effects may include the following:
Tachycardia
Hypotension
Cardiac dysrhythmias
Headache
Anaphylaxis
Vasodilation
Weakness
Convulsions
Single acute toxicity is rare.
Vitamin B-3 (ie, niacin, nicotinic acid)
Acute toxicity effects are prostaglandin-mediated and include flushing, pruritus, wheezing, vasodilation, headache, increased intracranial blood flow, headache, diarrhea, and vomiting.
Chronic toxicity effects include jaundice, abnormal liver function tests, signs and symptoms of liver toxicity (most common with sustained-release preparations), and acanthosis nigricans (rare).
Vitamin B-6 (ie, pyridoxine)
Effects include tachypnea and sensory neuropathies, such as burning pains, paresthesias, ataxia, clumsiness, paralysis, and perioral numbness.
Findings range from normal CNS function to progressive sensory ataxias, profound impairment of position and vibration sense, and diminished tendon reflexes.
Vitamin C
Effects may be renal colic (ie, kidney stones), diarrhea, nausea, rebound scurvy in infants born to women taking high doses, hemolysis if G-6-PD deficiency is present, possible dental decalcification, and increased estrogen levels.
Findings may include occult rectal bleeding.
I personally took tons of supplements for about 20 years & decided a couple of years ago that I was wasting my money. I now take a good multi vitamin for women & calcium supplementation. If you have a balanced diet, you are probably getting most of the nutrition necessary for good health. If you consume a lot of soda pop, you are probably robbing your body of much needed calcium. If you imbibe in too much alcohol, you may need to up your B-complex. Athletes & body builders need protein, but too much protein puts a strain on the heart & kidneys.
Hope this helps. BTW, I'm none too fond of rusty nails.

Chronic toxicity effects include all of the above, suppression of other antioxidants, and increased risk of hemorrhagic stroke.
Vitamin K
This particular toxicity is typically associated with formula-fed infants or those receiving synthetic vitamin K-3 (menadione) injections. Because of its toxicity, menadione is no longer used for treatment of vitamin K deficiency.
Effects may include jaundice in newborns, hemolytic anemia, and hyperbilirubinemia.
Toxicity also blocks the effects of oral anticoagulants.
Vitamins B-1, B-2, B-12, and folate
Effects may be minimal and nonspecific.
Vitamin B-2 turns the urine yellow-orange.
Vitamin B-1 (ie, thiamine) toxicity effects may include the following:
Tachycardia
Hypotension
Cardiac dysrhythmias
Headache
Anaphylaxis
Vasodilation
Weakness
Convulsions
Single acute toxicity is rare.
Vitamin B-3 (ie, niacin, nicotinic acid)
Acute toxicity effects are prostaglandin-mediated and include flushing, pruritus, wheezing, vasodilation, headache, increased intracranial blood flow, headache, diarrhea, and vomiting.
Chronic toxicity effects include jaundice, abnormal liver function tests, signs and symptoms of liver toxicity (most common with sustained-release preparations), and acanthosis nigricans (rare).
Vitamin B-6 (ie, pyridoxine)
Effects include tachypnea and sensory neuropathies, such as burning pains, paresthesias, ataxia, clumsiness, paralysis, and perioral numbness.
Findings range from normal CNS function to progressive sensory ataxias, profound impairment of position and vibration sense, and diminished tendon reflexes.
Vitamin C
Effects may be renal colic (ie, kidney stones), diarrhea, nausea, rebound scurvy in infants born to women taking high doses, hemolysis if G-6-PD deficiency is present, possible dental decalcification, and increased estrogen levels.
Findings may include occult rectal bleeding.
I personally took tons of supplements for about 20 years & decided a couple of years ago that I was wasting my money. I now take a good multi vitamin for women & calcium supplementation. If you have a balanced diet, you are probably getting most of the nutrition necessary for good health. If you consume a lot of soda pop, you are probably robbing your body of much needed calcium. If you imbibe in too much alcohol, you may need to up your B-complex. Athletes & body builders need protein, but too much protein puts a strain on the heart & kidneys.
Hope this helps. BTW, I'm none too fond of rusty nails.

Acute toxicity effects may include muscle weakness, apathy, headache, anorexia, nausea, vomiting, and bone pain.
Chronic toxicity effects include the above symptoms and constipation, anorexia, polydipsia, polyuria, backache, hyperlipidemia, and hypercalcemia.
Findings may also include calcinosis, followed by hypertension and cardiac arrhythmias.
I don't know where this comes from but it's simply scaremongering.
For up to date information about vitamin d spend some time reading the research at http://www.vitamindcouncil.com/ The Vitamin D council.
Anyone worried about vitamin d overdose should be aware that it's almost impossible to poison anyone with vitamin d. The only cases that have occured have happened from industrial accidents although there was this case http://www.ncbi.nlm.nih.gov/entrez/quer ... med_docsum of a 3 yr old who was given, owing to a misunderstanding, 2,400,000 IU over 4 days. Bear in mind the RDA is currently around 200iu daily so this represents the amount an adult should take daily for 32 years. Now can you name anything else where a toddler could take the total adult daily allowance for over 30 years worth, over a period of 4 days and suffer no more than a few days washout in hospital?
If you look at the research for vitamin d you will find that for most of the population are below the sufficiency level. If you look at cancer wards you will find 70% are vit d insufficient, for elderly folk who have fallen it's over 90%.
The problem is that folk aren't spending enough time outside in the sunshine and when they do go outside they cover themselves with sunblock.
Once you've read links from the Vitamin D council website homepage have a look at http://www.healthresearchforum.org.uk/reports.html The booklets Sunlight Robbery and Sunlight Vitamin D & Health
Anyone concerned about the accuracy of any of my statements and who is still worried about the alleged toxicity of vitamin d may want to read http://www.direct-ms.org/pdf/VitDVieth/ ... it%20D.pdf
Critique of the Considerations for Establishing Tolerable Upper Intake Levels for Vitamin D
With regard to Vitamin d it certainly is not the case that "If you have a balanced diet, you are probably getting most of the nutrition necessary for good health." this research Heaney RP, Davies KM, Chen TC, Holick MF, Barger-Lux MJ. Human serum 25-hydroxycholecalciferol response to extended oral dosing with cholecalciferol. Am J Clin Nutr.2003;77(1):204-10. here http://www.ajcn.org/cgi/content/full/77/1/204
shows that you use around 4000iu daily. Try explaining how to get that amount from your diet. You either have to regularly spend some time outdoors in the sunshine or use a high strength CHOLECALCIFEROL d3 supplement.
