Vitamin C, also known as ascorbic acid, is probably one of the most highly publicized, yet least understood, of all of the vitamins. Championed by Nobel laureate Linus Pauling, Ph.D., and advocated by many nutrition buffs, vitamin C is indeed a fascinating and important nutrient (or micronutrient) necessary for human life.

Hmm. . its pretty rare stuff so you are not going to hand out samples\nSince it was once used in lasers you could start your presentation with a laser light show, or just a simple laser pointer\nPresent the information chronologically, show how and why it was discovered (it started as a blank square on the Periodic Table of the Elelments) talk about it uses and why it was replaced\ngood luck

I think one of the biggest misconceptions about store-bought vitamins is that they are the same vitamins we get from food.  Most often, they're actually synthetic forms of what occurs naturally in food, and that synthetic, manufacured for is really scary!\n\n"Taking the synthetic form of vitamin C, for example, can actually thicken the arterial walls of the heart by as much as 2.5 times which can lead to heart disease and can do harm to the body! Ascorbic acid ( synthetic vitamin C ) is the word that you need to watch out for!\n\nTaking the synthetic form of vitamin A is proven to actually increase the rate of cancer which can do more harm than good to your body! But the whole vitamin A ( from vegetables ) actually does the exact opposite. Whole Vitamin A significantly reduces the rate of cancer! Most Vitamin nutrients on the market today use stripped down synthetic vitamins rather than whole vitamins straight from vegetables and fruits like our vitamin! Why? Synthetic vitamins are much cheaper to produce. \n\nTaking the synthetic form of Vitamin E is proven to actually suck vitamins and minerals right out of the bones which can do more harm than good to the body! Once again, most vitamin supplements today are using all the synthetic vitamins because they are cheap to manufacture."\n\nIt seems to me that synthetic vitamins, those that we normally find in the sotres, aren't the best option.  I use a food-based multivitamin so I get all those nutrients in their original form.\n\nHow do you know what you're getting?\n\n"Remember, next to the name of any vitamin, if you don't see a name of a food or an asterisk leading you to a place on the label that tells you the food source of the vitamins, you are more than likely looking at an inexpensive, processed vitamin that is stripped of all other compounds that are normally present with vitamins that are found in fruits and vegetables. If you see the name of a food referenced to the vitamin, be excited to know that you are getting vitamins direct from the whole food and, therefore, you are also getting the essential precursors, enzymes, activators, antioxidants, and micronutrients (essential compounds) that are naturally found with vitamins. These essential compounds make it much easier for the body to absorb and utilize the vitamins you are taking! Your body deserves to be given the right vitamins that are essential for your good health!"\n\nQuotes above from http://www.newbetteryou.com - more info available there.

(Host consciousness replies)\n\nAlfacalcidol is a D vitamin. There are many D vitamins so we can't say "just vitamin D". It is actually one of the compounds produced by the kidneys following consumption of any of the D vitamins. Because you take it ready made, it can therefore bypass this renal metabolism and is considered a good choice for patients with severe impairment of kidney function. (but is also commonly given to patients with perfectly normal kidneys!)\n\nI do not know what you mean by calcium gland.\n\nVitamin D (just about any) is commony given in combination with calcium. This is because the D vits increase the absorption of calcium from food. Ie you can correct a low calcium level by taking vitamin D. Better still, give vit D and calcium supplement together. \n\nIn UK we have Cacit D3 (spelling) which contains both 500mg calcium (as carbonate) and 440 IU colecalciferol (vit D2). This is a supplement used to correct low calcium levels, typically to reduce loss of calcium from bones in post-menopausal women.\n\nSorry, as to the rest, you must discuss with GP. It is clear you have some metabolic / electrolyte imbalance. It is being treated.  Without diagnosis impossible to comment.\n\nHope above of some use to you.

Here you go:\n\nHistory and Overview\nChromium is a relative newcomer to the recognized list of essential nutrients. In 1948, it was identified as an important component of plant and animal tissue, but it was not until 1977 that it was considered an essential nutrient.\n\n\nThe importance of chromium in human diets has been recognized only in the past 20 years. There is much to learn about this mineral, but chromium deficiency may be related to both diabetes and coronary heart disease.\n\n\nDr. Gary Evans of Nutrition 21, the manufacturer of chromium picolinate, was a former nutrition scientist with the U.S. Department of Agriculture. Dr. Evans discovered that picolinic acid could bind tightly to trace minerals such as chromium. He believed that combination of the two substances could possibly expedite absorption and nutritional efficiency. In response to a request from Nutrition 21, Dr. Evans created chromium picolinate. After testing the substance in laboratory rats, he concluded that it was “far better absorbed and retained than inorganic chromium.” The U.S. Department of Commerce later gave Nutrition 21 the exclusive license to produce and market chromium picolinate.\n\nDr. Walter Mertz has also conducted research with chromium and dietary yeasts. He identified the compound that binds insulin to cell membranes and helps to regulate normal blood sugar metabolism. He named this compound Glucose Tolerance Factor or GTF. It was Dr. Mertz’s theory that the combined effectiveness of chromium and niacin complexes are as effective as the GTF extracts from brewer's yeast, the richest known source of chromium in nature. The chromium-niacin product uses a patented “oxygen coordinated” complex and claims to be 300 percent more effective than chromium picolinate. Scientific acceptance of this claim has yet to be substantiated.\n\nNutrient Composition and Function of Chromium\nChromium is generally accepted as an essential nutrient that plays an important role in insulin action and thus influences carbohydrate, lipid, and protein metabolism. The specific biochemical function of chromium has not yet been clearly defined; that is the chemical nature of the relationship between chromium and insulin function has not been identified.\n\nThe most studied function of chromium is in relation to the maintenance of normal cell glucose uptake. Chromium’s function as a Glucose Tolerance Factor remains controversial, but it has been suggested that GTF-chromium helps to form a connection between insulin and insulin receptors that facilitate insulin-tissue interaction. Chromium, as found in brewer’s yeast and in some other naturally occurring and synthetic complexes, appears to be effective in stimulating glucose metabolism.\n\nChromium picolinate is a combination of biologically active trivalent chromium and picolinic acid. (Trivalent chromium is the biologically active form of chromium.) In fact, it is considered an isomer of nicotinic acid, and because of its structure, can form strong ties to chromium and other transition metals.\n\nChromium Picolinate is not believed to occur in nature and therefore is not recognized as an essential compound that will cause deficiency if it is absent from the diet. However, chromium picolinate’s role is thought to be similar to other forms of chromium such as that found in brewer's yeast.\n\nPurported Dietary Relationship of Chromium\nThe importance of chromium in human diets has been recognized only in the past 20 years. There is much to learn about this mineral, but low levels of chromium may be related to both diabetes and coronary heart disease.\n\nIn both animals and man, a chromium deficiency is characterized by impaired glucose tolerance and elevated serum cholesterol and triglyceride levels. Chromium deficiency appears most commonly in infants maintained strictly on breast milk whose mothers do not take a nutritional supplement, in children who are malnourished, and in the elderly.

I have not explanation for that..an exact one.At any rate that cannot be caused by the intake of your vitamins..You are lucky!

Interestingly enough...to add to ur findings...I have been told by my family doctor that most people do not need a vitamin if they are healthy adults who eat right.  And I have personally never been able to take centrum because it would always make my stomach sick.  I'm checking out that site now.

Get the book by Bruce Miller, DDS, CNS.Cancer. Nutrition Answers. In it he talks about Vitamin C. Or Books by Dr Kenneth Cooper. The Anioxidant Revolution.60 mg is WAY too low. After you've read any of these books, pass it to the sadly misinformed nutritionist!

Now, I read your Query, and I am going to advise you to get this situation checked. Because it's not normal (and you must be aware of that!) there may be an underlying health situation that needs your attention...how's your confront? It may be a simple thing that requires a handling, and then all will be well...as to vits to bring back the appitite, I've never really heard of such..Good luck and do what ya gotta do on this...

Hi Stony.  I am a chronic stone sufferer.  There is a lot of research on the role of citrate in the prevention of the most common types of stones - calcium oxalate stones.  I did a search of the medical literature on Pubmed and found a 1996 study in the Journal of Urology that looked at the use of lemon juice as a source of daily citrate.  This study found significant benefits to the use of 4 ounces of reconstituted lemon juice diluted in 2 liters of water and consumed each day.\n\nA more recent 2002 Italian study found that grapefruit juice also increased citrate levels in the urine.  However, it also found an increase in calcium and magnesium in the urine.  The researchers concluded that fruit juices may be helpful, but not if they contain sugar which can increase urinary calcium levels.\n\nPotassium Citrate supplements (I use these) are a well recognized therapy for reducing the risk of stone formation.  Additionally, calcium supplements (contrary to what seems 'logical'), especially calcium citrate, are also a good idea.  The increase in dietary calcium is thought to reduce the absorption of oxalates from the gut.  It is actually the oxalates in the urine (not calcium) that drive the formation of calcium oxalate stones.\n\nMagnesium supplements (again as magnesium citrate) are helpful too.\n\nLastly, vitamin B6 supplementation has be shown to also be beneficial.\n\nOne last thought.  After more than 25 years of recurring stones, last year (with the help of a great Naturpathic Physician) I was able to identify the underlying cause.  I have a condition called Celiac Disease.  This is a common autoimmune disease that damages the small intestine and causes excessive absorption of oxalates (and thus the chronic stones).  It is caused by an allergic reaction to the proteins in wheat, rye and barley called glutens/gliadins.  One person in every 100 is estimated to have Celiac Disease.  Sadly, it is only diagnosed in 1 in 3500 people in the U.S. (so 97% of the people with it go undiagnosed).  Medical doctors are very unaware of this common condition - partly because the 'common presenting symptoms' they are taught in medical school are actually NOT the most common symptoms of Celiac Disease.  It may be a good idea for you to get tested.  You may need to educate yourself about it, again because the M.D.s are not educated about it.  You can find a large series of review papers on it at the medical journal "Gastroenterology" in their April 2005 supplement.  These are available on the net.\n\nHope this is helpful to you.  Best wishes and good luck.

Vitamin C is still being studied to determine its efficacy, but one study has evidence showing that people who took vitamin C supplements daily for two weeks had an increase in certain white blood cells responsible for fighting viruses. Also there was an improvement in the general environment of the blood that would help to prevent viruses from taking hold. But the why is still unknown so far as I am aware.
