Can Diabetics Take Vitamin C Tablets

Vitamin C And Diabetes

Vitamin C And Diabetes

A new study has added to the growing amount of research showing that vitamin C- as well as a high intake of vegetables and fruits- may have protective effects against diabetes. This makes more than a little intuitive sense- after all Diabetes is a disease marked by a good amount of oxidative damage- damage done to your cells and DNA by rogue molecules called free radicals. Antioxidants- like vitamin C- can help protect against this. A cornerstone of the Atkins program has always been a diet high in antioxidants such as vitamin C, vitamin E, zinc and selenium, precisely because of their multiple protective benefits. In the current study, published in the July 28 edition of the Archives of Internal Medicine, researchers collected food questionnaires from over 21,000 subjects. The researchers also measured blood levels of vitamin C in all the participants. The subjects were then followed up for 12 years during which 735 individuals were diagnosed with diabetes (about .4% of the population studied). There was a significant inverse association between vitamin C levels in the blood and the risk of getting diabetes. In other words those patients with the highest blood levels of vitamin C at the beginning of the study were the least likely to be among those who developed diabetes. Since vitamin C is often a “marker” for fruit and vegetable intake- after all, we get 90% of our vitamin C from vegetables and fruits- the researchers decided to investigate the effect of fruit and vegetable consumption independently from blood levels of vitamin C. Using the questionnaires, they determined that indeed, fruit and vegetable consumption did protect against diabetes to some degree. But surprisingly, the protection was not nearly as dramatic as the protection obtained by high blood lev Continue reading >>

Faq : Vitamin Raises Blood Sugar? | Hoffman Center

Faq : Vitamin Raises Blood Sugar? | Hoffman Center

Q:I am a type 2 diabetic who takes 4,000 mg of vitamin C each day. I recently heard that C can raise your blood sugar. Is this true? A:Vitamin C is an important antioxidant for maintaining optimal health as well as managing infection and disease. It is hard to imagine such an important vitamin could cause adverse effects in anybody. I believe the conundrum of vitamin C raising blood sugar has several sources. A study in 2004 (Am J Clin Nutr 2004;80:1194-200) concluded a high vitamin C intake from supplements (just 300 mg or more) is associated with an increased risk of death from cardiovascular disease (CVD) in older women with diabetes. I have to take issue with this conclusion because it was extrapolated from the Iowa Womens Health Study which was designed to examine diet and lifestyle factors and the incidence of cancer and mortality, not vitamin C and its relationship to blood sugar. Fortunately, the authors responsibly note that their study had several limitations, one being there was only one diet and health assessment at the beginning of the study and secondly, the subjects in the study were self-reported diabeticsresearchers did not validate this important criteria. Fueling the conundrum are foods containing vitamin C, such as citrus fruit and juices. They can and will raise blood sugarespecially among diabetics. Fruit intake, let alone juice, has to be kept in check so as not to increase blood sugar. In this setting, high blood sugar is created by the fructose in fruit rather than any vitamin C contained in it. At the other end of the spectrum are reports that vitamin C in doses of 1,000 mg per day decrease blood sugar and improve Hemoglobin A1c in diabetes, while doses of only 500 mg did not significantly reduce blood sugar or HgbA1c (Indian J Med Res 2007;12 Continue reading >>

Effect Of Vitamin C On Blood Glucose, Serum Lipids & Serum Insulin In Type 2 Diabetes Patients.

Effect Of Vitamin C On Blood Glucose, Serum Lipids & Serum Insulin In Type 2 Diabetes Patients.

Abstract BACKGROUND & OBJECTIVE: Diabetes mellitus is one of the most common metabolic disorders that causes micro- and macro-vascular complications. Because of additive effects of hyperglycaemia and hyperlipidaemia for cardiovascular diseases, lipid abnormalities should be evaluated in diabetes. As vitamin C is known for its beneficial effects on serum lipids and glycated haemoglobin (HbA1c), we evaluated the effect of different doses of vitamin C on blood glucose, serum lipids and serum insulin in individuals with type 2 diabetes mellitus. METHODS: A total of 84 patients with type 2 diabetes referred to Yazd Diabetes Research Center, Iran, were included in the study. They received randomly either 500 mg or 1000 mg daily of vitamin C for six weeks. Fasting blood sugar (FBS), triglyceride (TG), total cholesterol (TC), low and high density lipoprotein (LDL, HDL), glycated haemoglobin HbA(Ic) and serum insulin were measured before and after vitamin C consumption and the results were analyzed. RESULTS: A significant decrease in FBS, TG, LDL, HbA1c and serum insulin was seen in the group supplemented with 1000 mg vitamin C. The dose of 500 mg vitamin C, however, did not produce any significant change in any of the parameters studied. INTERPRETATION & CONCLUSION: Our results indicate that daily consumption of 1000 mg supplementary vitamin C may be beneficial in decreasing blood glucose and lipids in patients with type 2 diabetes and thus reducing the risk of complications.

6 Of The Best Dietary Supplements For A Diabetic Diet—and 3 You Should Avoid

6 Of The Best Dietary Supplements For A Diabetic Diet—and 3 You Should Avoid

Should I take supplements? From cinnamon and magnesium to herbal formulas claiming to smack down high blood sugar, “diabetes-friendly” supplements are popping up in health food stores and drugstores and in the medicine cabinets of more and more people with diabetes. More than 50 percent of people with diabetes say they’ve used dietary supplements, according to one 2011 study—and at least one in four has given herbal remedies a try. The big question: Should you? “People with diabetes may be looking for something that seems less potent than a medication or something that will treat other health issues beyond blood sugar control, such as high cholesterol,” notes Laura Shane-McWhorter, PharmD, a University of Utah professor of pharmacotherapy and author of The American Diabetes Association Guide to Herbs & Nutritional Supplements: What You Need to Know from Aloe to Zinc. But experts are reluctant to recommend supplements to people with diabetes for two important health reasons. First, there’s virtually no research on long-term safety. Second, no supplement controls blood sugar as effectively as diabetes drugs (in combination with a healthy lifestyle). “There are no miracle treatments for diabetes,” Shane-McWhorter says. “The most important thing to know if you have diabetes is that no supplement will take care of it for you. Diabetes is a condition that can be well-controlled with a healthy lifestyle plus medication if needed. A supplement can’t replace those.” And new science is changing the supplement landscape. In consulting the latest research as well as supplement experts for this report on the best-studied and most widely used supplements, we found that some popular pills—chromium, we’re talking about you—aren’t living up to their reput Continue reading >>

Vitamin C Stops Blood Vessel Damage In Type 1 Diabetes

Vitamin C Stops Blood Vessel Damage In Type 1 Diabetes

Vitamin C Stops Blood Vessel Damage in Type 1 Diabetes Poor blood glucose control can lead to blood vessel and nerve cell damage in diabetics and the only known way to prevent this is to maintain healthy blood glucose levels, and even this does not always work. A recent research team, however, has found that combining insulin with vitamin C stops blood vessel damage in type 1 diabetics. Type 1 diabetics require insulin to maintain healthy blood glucose levels, which limits the risk of blood vessel damage, but insulin itself does not battle or stop blood vessel damage. In fact, some past research has demonstrated that once blood vessel damage begins in type 1 diabetics, it continues, even when blood glucose is properly controlled. Blood vessel damage, or endothelial dysfunction, results mostly from oxidative stress, and is a major reason that diabetics are at an incredibly high risk for cardiovascular disease. Oxidative stress in diabetics is also closely linked to neuropathy, retinopathy, and resulting pain, amputations and blindness. Vitamin C is an essential nutrient for all humans, and protects against numerous ailments, from common colds, to scurvy. Its anti-oxidant properties are what help in battling oxidative stress. Many citrus fruits, especially oranges, contain large amounts of vitamin C, as well as kiwi, broccoli, papaya, and many other fruits and vegetables. The following conclusions regarding vitamin C mixed with insulin are believed to be applicable to other anti-oxidants as well. Based on past successful research models that showed a combination of insulin and antioxidants helped stop cell and blood vessel damage, the current research applied this treatment to type 1 diabetics with previously poor blood glucose control, and resulting blood vessel damage.

However, deficiencies in vitamins C and D are re-emerging due to increased consumption of processed foods and reduced fresh foods in the Western diet, as well as to an indoor sedentary lifestyle away from sun exposure. These dietary and lifestyle factors also predispose one to diabetes and metabolic syndrome. Our understanding of the potential roles of vitamin C (an antioxidant) and vitamin D (a biologically active hormone) in disease is increasing. In this review, we present observational, interventional, and mechanistic studies that examine the potential links between vitamins C and D in reversing defects in glucose homeostasis and the prevention of type 2 diabetes. Studies suggest an association between vitamin C deficiency and diabetes. An association between vitamin D and insulin resistance has been well described; however, the role of vitamin C and D supplementation in diabetes and its prevention requires further controlled trials. Keywords: glucose homeostasis, diabetes, insulin resistance, vitamin C, vitamin D Nutrients play essential roles in health and the prevention of disease. Nutrients, including vitamins, are vital to cardiovascular health (ie, vitamin B1), nerve function (ie, vitamins B6 and B12), the production of red blood cells (ie, folate and vitamin B12), and coagulation (ie, vitamin K), among man Continue reading >>

Best Vitamins For Diabetics

Best Vitamins For Diabetics

Eating a varied diet rich in natural sources of vitamins is a good idea for diabetics. Nutritional support is critical for diabetics because diabetes tends to drain nutrients. When levels of glucose are high in the blood, the body tries to ‘wash’ the excess sugar out. This is why diabetics need to use the washroom frequently. Unfortunately, diabetics also lose nutrients via their urine. Research studies show that diabetics are repeatedly found to be deficient in important water-soluble vitamins and minerals. What’s more, the loss of these vitamins worsens the body’s ability to manage blood sugar, creating a vicious cycle. Combining a healthy diabetes diet plan and a daily exercise routine with the best vitamin supplements for diabetics goes a long way in achieving stable blood sugar levels. What Vitamins Are Diabetics Deficient In? The term vitamin is short for “Vital Amino Acid”. This means that these are vital for the proper functioning of hundreds of chemical processes in the body which the body cannot manage by itself. Proper blood sugar control is one such function for which vitamins are critical. There are 13 essential vitamins that the human body requires and they must be obtained from an external source — through food and/or supplements. Diabetics need two kinds of vitamins: Water Soluble – Vitamins B1, B2, B3, B6, B12, C, Biotin, and Folate are water-soluble and cannot be stored in the body for longer periods of time. Diabetics are often deficient in these vitamins since they pass greater amounts of urine daily. As their body tries to get rid of extra sugar, diabetics lose more water-soluble vitamins than most others. That’s why diabetics need to to get these vitamins daily in doses larger than what normal people need. Luckily, you can get all Continue reading >>

Too Much Vitamin C Not Good For Diabetics’ Hearts

Too Much Vitamin C Not Good For Diabetics’ Hearts

Too Much Vitamin C Not Good for Diabetics’ Hearts Older women with diabetes who take high doses of vitamin C for the sake of their hearts may be doing more harm than good. The study, which followed nearly 2,000 postmenopausal women with diabetes for 15 years, found that those who took heavy doses of vitamin C supplements — 300 milligrams (mg) a day or more — were roughly twice as likely to die of heart disease or stroke compared with women who took no supplemental C. The researchers did find statistically weak evidence that lower supplement doses — up to 99 mg per day — curbed the risk of cardiovascular death, and high intakes of vitamin C from food were not related to a greater risk of death from cardiovascular causes. According to the researchers, their results suggest that taking supplements to correct the lower blood levels of vitamin C commonly seen in diabetes is not necessarily the right choice. And though the research focused on older women, the findings may apply to men as well, according to the study’s senior author. Dr. David R. Jacobs Jr., of the University of Minnesota in Minneapolis stated that, "Our results, if confirmed by other research, would suggest that diabetics should be more cautious than others about taking supplements." The current recommended dietary intake for vitamin C is 90 mg a day for men and 75 mg per day for women. Vitamin C is an antioxidant, meaning it helps neutralize potentially cell-damaging substances known as oxygen free radicals, which are a normal byproduct of metabolism. While the vitamin is clearly necessary for good health, studies have garnered conflicting results on whether supplements help lower the risk of heart disease and stroke. In addition, Jacobs and his colleagues note in the report, although people with Continue reading >>

Vitamin Supplements For People With Diabetes

Vitamin Supplements For People With Diabetes

Do people with diabetes need vitamin supplements? And if they do, which ones should they consider taking? Eating balanced meals and snacks is important for staying healthy and maintaining good glycemic control, emphasizes Nora Saul, M.S, R.D., L.D.N., C.D.E, a patient educator with the Joslin Clinic. Choosing whole foods over supplements is advantageous since foods provide a myriad of different nutrients for health in one package, whereas single vitamin supplements are single purpose. For example, raspberries contain vitamin C, fiber and antioxidants, Saul points out. In fact, the use of supplements is usually not supported unless a deficiency state is suspected. Well controlled diabetes does not increase the need for supplementary vitamins and minerals. So who could benefit from a vitamin supplement? Those on low calorie diets, who do not eat a variety of foods Those following vegan diets Pregnant women Those whose medical conditions require a restricted diet, such as people with certain food allergies, kidney disease or diseases of the gastrointestinal tract that interfere with nutrient digestion or absorption. One vitamin that many people, including those with diabetes, may need supplementation of is vitamin D, Saul emphasizes. Although the current government recommendation is 400 IUs recent research has indicated that this may not be enough. In addition to being important for maintaining healthy bones, vitamin D may play an important role in blood glucose (sugar) control. We get vitamin D both from foods and the sun. Unfortunately, there are few dietary sources of vitamin D and for those of us in the Northern latitudes; the winter sun is not strong enough to allow our bodies to manufacture the amount we need. For many of us taking a supplement with 800 to 1000 IU pe Continue reading >>

4 Incredible Benefits Of Vitamin C For Diabetes

4 Incredible Benefits Of Vitamin C For Diabetes

Home / Type 2 Diabetes / 4 Incredible Benefits Of Vitamin C For Diabetes 4 Incredible Benefits Of Vitamin C For Diabetes Vitamin C is needed by the body for various essential functions and for a healthy immune system. Among its various benefits, the vitamin is beneficial for preventing diabetes and helping diabetics in coping up with the illness. According to a study, people who consume food rich in Vitamin C have a 22% lower risk of developing diabetes as compared to those who didnt. And those with adequate level of the vitamin in their blood have a 62% lower risk of diabetes. In diabetes, the cells and DNA get damaged by free radicals. Vitamin C is an antioxidant that helps prevent this damage. Stops diabetes-induced blood vessel damage According to a new research published by The Journal of Clinical Endocrinology and Metabolism, intake of a combination of insulin and Vitamin C may prevent diabetes-induced blood vessel damage, or endothelial dysfunction.Cells have memory, allowing damage to continue even after blood glucose has been brought within the target range. But this vitamin erases this memory of the cell and restores the functioning of the cell. This halt helps prevent complications of the heart, kidneysand eyes. Diabetes produces greater levels of oxidative stress in the body. Therefore, patients with diabetes type 2are more likely tosuffer from anxiety, depression and stress. This has an adverse effect on neurotransmitters, which are needed for many vital functions of the body. This damage iscontrolled by the consumption of Vitamin C as it can reduce cortisol in stressful situations. Cortisol is the hormone, which is released during stressful situations. All of these benefits make Vitamin C one of the essential vitamins for diabetics. Broccoli, cabbage, cau Continue reading >>

The Best Supplements For Diabetes

The Best Supplements For Diabetes

While eating a healthy diet (which includes mini-fasting) and exercising regularly are necessary to lower blood sugar naturally, these are not the only parts of my natural approach to managing diabetes. Nutritional support is also a key component of achieving healthy blood sugar levels. Supplements to Maintain Healthy Blood Sugar Levels Are Critical One reason nutritional support is so important is because diabetes is a nutritional wasting disease. Elevated glucose levels act like a diuretic and cause substantial loss of nutrients in the urine. Therefore, people with type 2 diabetes are likely to be deficient in important water-soluble vitamins and minerals. Incredibly, most experts specializing in diabetes make no attempt whatsoever to replace lost nutrients, leaving their patients to suffer the inevitable consequences of nutritional deficiencies. A second reason nutritional supplements are essential is that certain nutrients work to support your body’s ability to use insulin, which can help you maintain healthy blood sugar levels. Anyone who has diabetes should—at a minimum—take a high-quality vitamin and mineral supplement every day. Research has shown that taking a potent daily multivitamin dramatically reduces the incidence of infection and the number of sick days taken by patients with type 2 diabetes. Must-Have Supplements for Diabetes In addition to a multivitamin, make sure you are getting the following nutrients to help maintain healthy blood sugar levels. Many are included in multivitamins, but not always at the dosages I recommend. If your multi comes up short, supplement with additional doses of the specific nutrients until you’re taking the recommended amount. B-Complex Vitamins Vitamins B6 and B12 specifically support nerve health, which is critic Continue reading >>

Is It Safe To Take Supplements If You Have Diabetes?

Is It Safe To Take Supplements If You Have Diabetes?

You will find supplements for anything and everything these days. Even when you do not suffer from an ailment, supplements are suggested to keep you healthy and ailment-free. According to CDC, use of supplements is common among US adult population – over 50% adults used supplements during 2003-2006, with multivitamins/multiminerals being the most commonly used. So when you are a diabetic, especially if you have prediabetes and type-2 diabetes, you may find yourself confronting a large number of options for supplements that claim to support, reduce and even cure your diabetes. Diabetes is quite a frustrating disorder and you may find yourself tempted to try out these supplements one after another. But is it really safe to take supplements when you are a diabetic? Let us find out. But before that you need to understand what exactly supplements are. Defining Supplements As the name suggests, a supplement is anything that adds on to something. A dietary supplement is therefore something that one takes in addition to one’s diet to get proper nutrition. US Congress in the Dietary Supplement Health and Education Act defines dietary supplements as having the following characteristics: It is a product that is intended to supplement the diet; It contains one or more dietary ingredients (including vitamins, minerals, herbs and other botanicals, amino acids, and other substances) or their constituents; It is intended to be taken by mouth as a pill, capsule, tablet, or liquid; It is not represented for use as a conventional food or as sole item of a mean or a diet; and, It is labeled on the front panel as being a dietary supplement. Now let us look at some general benefits and risks of taking supplements. We will discuss these in context of diabetes later in the article. Benefit Continue reading >>

Ways To Make Nutritional Progress Against Diabetes

Ways To Make Nutritional Progress Against Diabetes

Diabetes Home WAYS TO MAKE NUTRITIONAL PROGRESS AGAINST DIABETES (Introduction by Abram Hoffer, M.D.: Reading this chapter will report what can be done over and above the use of insulin and classical dietetics. I am very familiar with Type I (insulin dependent diabetes or juvenile diabetes), as two members of my family have it. As this is not a medical text, the author does not describe the symptomatology and treatment using insulin. (By the way, doctors who treat diabetes are practicing orthomolecular medicine without knowing it, for they are using a hormone that is naturally present in the body.) Dr. Saul lists and describes both positive and negative factors in dealing with this condition. Thus for Type I, we have on the positive side the B complex vitamins, especially vitamin B-3, and vitamin C. The negative factors are diets which are too rich in free sugars and not rich enough in the complex carbohydrates. Negative factors also include milk, fluoride, coffee and vaccinations. When it is started at an early age, niacinamide will prevent diabetes from developing in many children born to families prone to the disease. I have also found niacin very helpful in preventing patients from suffering the long term ravages of diabetes, which are not directly due to high blood sugars, but to the side effects involving the vascular system. Niacin lowers total cholesterol, elevates HDL, and prevents the development of arteriosclerosis. Therefore these patients are less apt to become blind and lose their legs. With medical supervision, it may be used safely in dealing with diabetics, but you will need to find a doctor who knows niacin. Dr. Saul provides supporting references to the literature, which physicians will benefit from seeing. I was especially pleased to see that he cite Continue reading >>

Supplementation Of Vitamin C Reduces Blood Glucose And Improves Glycosylated Hemoglobin In Type 2 Diabetes Mellitus: A Randomized, Double-blind Study

Advances in Pharmacological Sciences Volume 2011 (2011), Article ID 195271, 5 pages 1Department of Pharmacology, Indira Gandhi Government Medical College, Nagpur 440018, India 2Department of Pharmacology, Shree Sathya Sai Medical College and Research Institute, Chennai 603108, India Academic Editor: Mustafa F. Lokhandwala Copyright © 2011 Ganesh N. Dakhale et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Abstract No study has ever examined the effect of vitamin C with metformin on fasting (FBS) and postmeal blood glucose (PMBG) as well as glycosylated hemoglobin (HbA1c) in the treatment of type 2 diabetes mellitus (DM). The goal was to examine the effect of oral vitamin C with metformin on FBS, PMBG, HbA1c, and plasma ascorbic acid level (PAA) with type 2 DM. Seventy patients with type 2 DM participated in a prospective, double-blind, placebo-controlled, 12-week study. The patients with type 2 DM were divided randomly into placebo and vitamin C group of 35 each. Both groups received the treatment for twelve weeks. Decreased PAA levels were found in patients with type 2 diabetes mellitus. This level was reversed significantly after treatment with vitamin C along with metformin compared to placebo with metformin. FBS, PMBG, and HbA1c levels showed significant improvement after 12 weeks of treatment with vitamin C. In conclusion, oral supplementation of vitamin C with metformin reverses ascorbic acid levels, reduces FBS, PMBG, and improves HbA1c. Hence, both the drugs in combination may be used in the treatment of type 2 DM to maintain good glycemic control. 1. Introduction Diabetes mellitus (DM) is Continue reading >>
