Wondering about the bioavailability regarding vitamin c from natural or sythetic sources. I am specifically looking for studies or scientific proof of the negative effects of sythetic vitamins and specifically vitamin c.

Vitamins are made up of several different components enzymes, co-enzymes, and co-factors– that must work together to produce their intended biologic effects.Vitamins that are found naturally in whole foods come with all of their necessary components.The majority of vitamins that are sold in pharmacies, grocery stores, and vitamin shops are synthetic vitamins, which are only isolated portions of the vitamins that occur naturally in food.

There has been research indicating that massive doses of synthetic vitamin C can cause kidney stones, but I wouldn't worry about it if you're taking 5000mg per day or less.\n\nYour kidneys also have to filter it, so taking a lot more than you need can create an extra burden on that organ.

I do not have any personal experience with this product but a little web research lead to some interesting findings.\n\nFirst, this product appears to consist of vitamins, minerals, fish oils, some herbs and some related nutrients.  Many of these basic nutrients play important roles in brain function and health, but whether the quantities and quality of these items in this product will benefit brain function and memory in the majority of people is unproven.  \n\nSecond, according to the website "Consumeraffairs.com", "The Federal Trade Commission obtained a $1 million settlement from the firm in 2004.  Prosecutors charged them with making unsubstantiated claims for their products."\n\nUsually products like this, that are highly promoted on TV (expensive!) are too expensive (over priced) and promoted with excessive claims (the FTC settlement).  It may be wiser and more cost effective to just take a quality multi-vitamin/mineral supplement (from your local health food store - not Centrum or One-A-Day, which are the 'junk-food' of vitamin supplements) and a quality fish oil supplement and/or cod liver oil.\n\nYou might consider reading an excellent book on this subject by David Perlmutter, M.D., Board certified Neurologist and recipient of the Linus Pauling Award in Medicine.  The book is called: "The Better Brain Book" and it is available at Amazon.com.  You will learn a lot about the role of basic nutrients in brain health as well as info. about special nutrients (lipoic acid, CoQ10, NAC, etc.) from this book.\n\nHope this was helpful.

Wow..thanks for the info. I truly believe in "natural cures" to prevent and cure cancer. \nI wish more people would at least look further into a natural approach such as eating an all organic diet and whole foods, herbs, etc. for a cure BEFORE going through all the pain and agony of traditional cancer treatments, chemo and synthetic drugs. \nDrugs made by the drug companies who could care less about finding a cure for cancer. If they did ..they would go out of business!

Please listen to me as I am only here to help. You have to do exactly as I say. Go to the website and look up CESIUM CHLORIDE AND OXYGEN DROPS. The other ones could be green algae and paw paw, etc etc. These medicines are known in the medical field, but they dont talk about it. Because these are natural remedies with no toxic chemicals in it. So, thats why they cant profit from it. If they cant profit, they dont sell. I mean, some are even made of mushrooms that you can grow anywhere. Why would they promote this? These doctors will never make money. So, the FDA has put a restriction on these remedies. They cannot say anything about cancer on their labels. They have to be sold as vitamins or health products. But, the website can tell you how to use it, and what cancers it can cure. See how they are suppressing the world? In fact these treatments can cure up to 90% of patients that doctors have already given up on. Chemo therapy is not a therapy. I would rather die then go through with that. They try to kill your cancer with chemicals and radiation. If they kill all your cancer before they kill all your body cells, then they consider you cured. But, what about after that? Your body is damaged and your health deteriorated. There is almost no recovery to this. How many people you know live past 5 years after chemo therapy? Not much if any at all. And compared to the masses, its almost nothing. What do you have to live with after chemo? Your body is not sunburned, its practically microwaved. CESIUM CHLORIDE can be taken with OXYGEN DROPS. Go to the websites. You can go to these websites and they will give a whole package for you to buy. You can take these medicines over the course of 3 months, a year, or whatever they prescribe. After your mom is feeling well, taking it for about 2 months or more, you can almost garauntee that you are cured. But, you have to listen to them and take it till they tell you to stop. They even cure certain 3rd stage cancers with a 90% success rate. But, time is of the essence so I urge you to buy it as soon as possible and take next day delivery or something. I wish you the best of luck in the future. But, heed my warning, do not go into chemo. They always tell you something fuzzy like, oh..you might live another 2 years, or you might die right away..etc etc....Then how do you decide? But, they always say that people who have been on chemo will only live a maximum of X years after that.  So, if you do exactly what I say, not only will you have a chance to survive, but all your friends that may get cancer...

I can only tell you the empirical formula of Vitamin C\n\nVitamin C (ascorbic acid) contains 40.92 % C, 4.58 % H, and 54.50 % O, by mass. The experimentally determined molecular mass is 176 amu. What is the empirical and chemical formula for ascorbic acid?\n\nIn 100 grams of ascorbic acid we would have: \n\n40.92 grams C \n\n4.58 grams H \n\n54.50 grams O\n\nI've gone through with those science fair projects.  I suggest that you should present something that could help the environment.  Like my project way back,  I made a fuel cell car.  The car will run bcoz of water not bcoz of gasoline... the process is done through using solar cells.  I decided to have such a simple design and there are lots of sunlight here in our country.  \n\nThough my project seems to be everywhere now with major inventions,  I just presented my own angle of invention, like a simplified one.  \n\nWith your other questions, I'm not familiar with it. Is it something to do with like that of electrical engineering... spinning around or stuff?  \n\nSo, I advice you to have a practical science fair project and since you are in tenth grade, is it something to do with phyiscs?  Out of the world inventions is far beyond... you are still a student but if you want to ba an inventor someday, maybe this is the chance to search and search and search.\n\nMy suggestions,\n\nLook and seek help to your friends, family, inventor (if possible), teacher, etc.  Read books of your interest and concentrate to a project you really want to.  Of course, list all possible projects you like, pros and cons, practicality, and of course, wise spending and safety.  You shouldn't think that you must win the first priwe, all you have to do is to persevere, be determined, think something unique and try to (if ever) look on other work of your competitors... maybe it might help on some idea. \n\nWell, those suggestions are taken from my own experience.  I didn't take any competitons though and it is a requirement.\n\nI guess I take this so long. Good Luck!  I hope I somewhat help you.

Vitamins are obtained from your food. A tablet can help to make up for a deficiency in your diet, but it is a 'second-best' source.\n\nBecause of industrial production methods (including farming), some vitamins are difficult to get from the foods that would naturally contain them. Organic food is better in this repect.\n\nSome vitamins are also useless without enough of the 'co-factors' that allow you to use them effectively.\n\nMost vitamins are not stored in your body in toxic quantities, but fat-soluble vitamins can build up in your 'adipose' (fat storing) tissues, and may occasionally reach toxic levels.\n\nFor example, large amounts of Vitamin A (Retinol) can be dangerous if you are pregnant. (Beta-Carotene is a good substitute; your body makes it into retinol if it's needed)\n\nThe short answer is: THE RIGHT AMOUNT of any vitamin is good for you, whether you get it from foods or out of a bottle. \n\nToo little will cause a deficiency; too much of some vitamins can poison you.

Echninacea helps boost your immune system.  If possible, buy it from a health food store as opposed to something like Walgreens.  There is a wide variation in quality.  \n\nDitto regarding the comment from the person about taking vitamin C.  Vitamin C is water soluble so you technically can't overdose on it, but try to space it out throughout the day as your body can only absorb so much at a time.  \n\nIf you do get to go to a health food store, buy vitamin C from a naturally derived "whole foods" source.  I have tried at least a dozen brands and find the "whole food" source is most effective.  It's made from real food, so your body recognizes it and seems to utilize it better.  One brand I recommend is Garden of Life Living Vitamin C.

Regardless of what supplement you choose, make sure the supplement is "Chelated". This means that it is tagged with an amino acid so that your body can actually recognize it, and absorb and use it. Most once a day type vitamin supplements that you can purchase off the shelf at any retail store are not chelated. If you are using a supplement that is not chelated, then you are putting it in one end, and flushing it when it comes out the other! That equates to nothing more than a waste of time and money. I personally have a complete wellness system that I use, and all of my family members use. It has truly impacted my overall health and well-being.

The most commonly implicated species are A. ochraceus and ostianus, P. viridicatum, griseofulvum and possibly solitum.1 Recent evidence shows that these mycotoxins are present in a variety of foods (cereals, pork, poultry, coffee, beer, wine, grape juice and milk. Analyses of these food products demonstrated that ochratoxins are also produced by P. vercucosum and A. niger and carbonarius.2,3\n\nThere are three generally recognized ochratoxins, designated A, B and C. Ochratoxin A (OTA) is chlorinated and is the most toxic, followed by OTB and OTC. Chemically they are described as 3,4-dihydro-methylisocoumarin derivative linked with an amide bond to the amino group of L-b-phenylalanine (Fig. 1).4\n\nFigure 1. Chemical Structure of Ochratoxin A (OTA); Adapted from Hussein et al, 2001, ref. 4\n\nThe role and risk assessment of OTA in animal and human disease has been reviewed. The tolerable dosage in humans was estimated at 0.2 to 4.2 ng/kg body weight based upon NTP carcinogenicity study in rats. OTA is mutagenic, immunosuppressive and teratogenic in several species of animals. Its target organs are the kidneys (nephropathy) and the developing nervous system.5,6 Following intravenous administration OTA is eliminated with a half-life from body in Vervet monkeys in 19-21 days.7 There is no reason to suspect that the elimination half-life would be significantly different in humans. OTA has been detected in human blood and milk. Other than nephropathy and urinary tumors, the evidence for human toxicology is scant. The toxicology of OTA will be briefly reviewed.\n\nCarcinogenesis\n\nThere is inadequate evidence that OTA is carcinogenic in humans. There is sufficient evidence in experimental animals. Overall OTA is possibly carcinogenic to humans and is a Group 2B carcinogen.\n\nResearch Animals: Oral administration of OTA produced tubular cell carcinomas of the kidneys in male and female rats, and fibroadenomas of the mammary gland in the females.1\n\nAdministration of OTA in the diet of ddy mice produced tumors of kidneys: solid renal tumors and cystic adenomas. Also, hepatic-tumors and hyperplastic liver nodules were found and unspecified lung tumors. In addition, solid renal-cell tumors occurred in ddd mice fed OTA in their diet.1\n\nMale and Female Fischer rats given oral doses of OTA had does related increased in kidney tumors: renal-cell adenomas, and renal-cell adeno-carcinomas. Metastasis of the renal cell tumors occurred in 17 males and one female.1\n\nHumans: Balkan endemic neuropathy (BEN) associated with OTA occurs in Europe (Bulgaria, Croatia, Turkey, Egypt, and Yugoslovia) where OTA is relatively high in the diet. Individuals with BEN were surveyed for the presence of urinary tract tumors. The incidence of tumors in the urinary system was elevated in both men and women. Furthermore, the observations suggested that individuals with urinary tract tumors had elevated levels of OTA in the blood and urine. Approximately one-third of patients dying from BEN have papillomas and/or carcinomas of the renal pelvis, ureter or bladder.1,8 -12\n\nRecently, it has been suggested that OTA can cause testicular cancer in humans.13 The hypothesis that consumption of foods contaminated with OTA causes testicular cancer was tested. The incidence of rates of testicular cancer in 20 countries were significantly correlated with the per-capita consumption of coffee and pigmeat. Scwhartz concluded: "Thus, OTA is a biologically plausible cause of testicular cancer. Future epide

Don't believe everything you read.  Be reasonable.  Are you aware that there is a link between people who eat carrots and those same people having auto accidents?  Anyone or company can make a case for anything.  We have to be aware of the type of study that was performed.  Was it a double blind study, a clinical trial, clinical study, or an abstract?  In other words, how valid is the study's results.  Did this article appear in a medical journal or in a "vegan" magazine.  Be a little skeptical and question the things you read.  By the way, all those "natural" products, crystals etc. work to a degree, but everyone that I've known who use them stink.  Good luck.

The research community is currently answering that.  They suspect that antioxidants may help, and there is some hopeful evidence of that, but nothing concrete yet.  There are a couple of studies that show that Coenzyme Q10 (aka CoQ10) helps people living with Parkinson's disease.  The most well-known study appeared in the Archives of Neurology in 2002.  It was compelling enough to get the National Institues of Health to fund research that is still going on about CoQ10.  \n\nThe current dose that people are speculating is beneficial is 1200 mgs per day - a pretty large dose.  It can also get a little pricey, because it is popular right now thanks to its benefits to the heart too.\n\nExercise also appears to have some very positive effects, if you call that natural.  \n\nOther than that, there are not a lot of other good natural options - that we know about yet.  I hope that we learn something miraculous soon.

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.

The recommended daily allowance for vitamin C varies. The current recommendation for adults is 120 mg daily, although a dose of 60 mg daily is all that is required to prevent scurvy. Some experts think the level should be as high as 200 mg daily to match the level present in 5 servings of fruits and vegetables daily, a diet shown to decrease cancer risk.\nMegadoses of vitamin C have not been shown in clinical trials to reduce viral illnesses such as colds. Large doses of vitamin C, ie, more than 1 g/d, may increase the risk of certain illnesses such as kidney stones, particularly oxalate stones.

If you are interested in a 100% natural whole food approach, I highly recommend ViaViente.  High blood pressure runs in my husband's family.  He tried dietary changes, high-cardio workouts, but nothing seemed to work.  He was getting prescribed medications but it didn't sit well with him that he is only 38 and would have to take hi BP meds.  So, his personal trainer/nutritionist and wife (who is a doctor), turned him on to ViaViente (which they recommend to all their clients/patients who are interested in natural approaches to combat nearly any health ailment imaginable).  After 3 weeks, his blood pressure went from 140+ to 117.  It has been 3 months now and it is at a stable 110.\n\nI know a network of trainers, nutritionists, doctors, physical therapists and herbalists who highly recommend this product.  It has also helped me with my lifelong allergy problem (I no longer take any meds) and my kids have not had a drop of Motrin or Tylenol since they've been drinking this juice (I used to feel like I was drugging my kids because they used to get sick so often).  My family loves it and we highly recommend it for preventative health, maintenance...your body just operates at an optimal level with ViaViente added to your diet.  4 ounces a day is equivalent to 20 servings of fruits and vegetables.\n\nYou are welcome to contact me directly and I can answer additional questions you may have.  I did quite a bit of research on the product and it's nearest competitors.
