1 Professor and BOS Chairperson, Institute of pharmaceutical sciences, CPS, IST, JNTUH, Hyderabad, Telangana, INDIA. * 2 Institute of pharmaceutical sciences, CPS, IST, JNTUH, Hyderabad, Telangana, INDIA. Received on: 04-09-2017; Revised and Accepted on: 22-09-2017 Asimple, rapid, and precise reverse phase high performance liquid chromatographic (RP-HPLC) method for simultaneous analysis of Chromium picolinate and metformin has been developed and validated in its bulk. This method was performed with a symmetry C18 (250 4.6 mm), packed with 5m particle column with 45:55v/v, Methanol and water as mobile phase at a flow rate of 1.0 ml/min. UV detection at 254 nm; chromium picolinate and metformin were eluted with retention times of 3.006 & 5.297 min, respectively. The method was continued and validated accordance with ICH guidelines. Validation revealed the method is rapid, specific, accurate, precise, reliable, and reproducible. Calibration curve plots were linear over the concentration ranges 200-1000 ppm. Limits of detection (LOD) were 0.33 and 0.32g/ml and limits of quantification (LOQ) were 1.01 and 0.98 g/mL for chromium picolinate and Metformin respectively. The developed method validated in terms of linearity, accuracy, precision, LOD, LOQ and robustness. The proposed method is highly sensitive, precise, accurate and easy to perform and was successfully applied in bulk form. KEYWORDS:RP-HPLC, Chromium Picolinate and Metformin, Quality control, Validation. Chromium picolinate is chemically Tris (picolinate) chromium.

It is a cofactor for insulin action [1]. Metformin is chemically 1,1- Dimethyl Biguanide. M Continue reading >>

Chromium Confusion

Chromium Confusion

Who would have thought that a trace mineral could cause so much confusion? As a dietitian, I remember many of my patients asking me if they should take chromium supplements. It was always a gray area for me, based on the ever-changing research. Chromium is called a trace mineral and is essential to the human body. It’s needed to help process carbohydrate, protein, and fat, and it enhances the action of insulin. Chromium is found primarily in two different forms: trivalent chromium, the kind found in food, and hexavalent chromium, a toxic form found in some chemical substances. Food sources of chromium include meat, chicken, eggs, liver, some fruits and vegetables, whole grains, and brewer’s yeast. However, the amount of chromium in food can vary depending on agricultural and manufacturing processes. According to the Institute of Medicine, a component of the National Academy of Sciences, adequate daily intakes of chromium for adult women and men range from 24–35 micrograms (mcg) per day, with men needing more than women. The link between chromium and diabetes originated in the 1950s, when researchers were able to prevent diabetes in rats by feeding them brewer’s yeast. Chromium was deemed to be the magic ingredient and was thereafter called a “glucose tolerance factor,” or GTF for short. Since then, quite a bit of research has been done to study the effect of chromium on various health conditions, primarily in the areas of diabetes, lipid control (including cholesterol and triglyceride levels), and weight loss. Back in 2004, interest was sparked when researchers reported a link between chromium picolinate supplements and improved insulin sensitivity and glucose tolerance in people with diabetes. But, after more scrutiny, the conclusion was that most of the pr Continue reading >>

Metformin is a drug used to lower blood sugar levels in people with non-insulin-dependent (type 2) diabetes . Types of interactions: Beneficial Adverse Check Metformin therapy has been shown to deplete vitamin B12, and sometimes, but not always, folic acid as well. This depletion occurs through the interruption of a calcium-dependent mechanism. People taking metformin should supplement vitamin B12 and folic acid or ask their doctor to monitor folic acid and vitamin B12 levels. Metformin therapy has been shown to deplete vitamin B12, and sometimes, but not always, folic acid as well. People taking metformin should supplement vitamin B12 and folic acid or ask their doctor to monitor folic acid and vitamin B12 levels. The interaction is supported by preliminary,weak, fragmentary, and/or contradictory scientific evidence. In a small, controlled study, guar gum plus metformin slowed the rate of metformin absorption. In people with diabetes this interaction could reduce the blood sugar-lowering effectiveness of metformin. Until more is known, metformin should be taken two hours before or two hours after guar gum-containing supplements. It remains unclear whether the small amounts of guar gum found in many processed foods is enough to significantly affect metformin absorption. The interaction is supported by preliminary,weak, fragmentary, and/or contradictory scientific evidence. In a preliminary trial, administration of Ginkgo biloba extract (120 mg per day) for three months to patients with type 2 diabetes who were taking oral anti-diabetes medication resulted in a significant worsening of glucose tolerance. Ginkgo did not impair glucose tolerance in individuals whose diabetes was controlled by diet. Individuals taking oral anti-diabetes medication should consult a doctor b Continue reading >>

Supplementation With Chromium Picolinate: Therapeutic For Diabetes And Pre-diabetes

Supplementation With Chromium Picolinate: Therapeutic For Diabetes And Pre-diabetes

Supplementation with a form of the trace mineral chromium called chromium picolinate is prudent nutritional therapy for your patients with diabetes and pre-diabetes. To give you an overview of why I say this, most of the studies involving supplemental chromium for type II diabetes have shown positive results of one type or another. However, when chromium picolinate, which is the most bioavailable form, has been used, all of the studies have yielded positive results (in blood sugar, blood insulin and/or blood lipid [cholesterol and triglyceride] readings).[i] One of these studies, a 1997 study involving 180 type II diabetes patients in China, is a classic: it documented “spectacular” results in diabetes patients who took 500 mcg chromium picolinate twice daily. After four months, nearly all of the diabetes patients no longer had traditional signs of diabetes. Their blood sugar and insulin levels dropped to near normal—something that medications could not achieve. Even more importantly, the “gold standard” diagnostic measure of diabetes—blood levels of hemoglobin A1c (sugar-damaged proteins that age cells)—also dropped to normal.[ii] A follow-up study by some of the same researchers monitored 833 type II diabetes patients who took 500 mcg chromium picolinate twice daily: a significant reduction in fasting blood sugar levels and in post-meal blood sugar levels was found during the ten months of the study. No negative side effects were shown from taking the supplements. In addition, more than 85 percent of the patients reported improvements in the common diabetic symptoms of excessive thirst, frequent urination and fatigue.[iii] Although the incidence of type II diabetes is increasing in record numbers, many people don’t yet have diabetes but are at high ris Continue reading >>

Background: Chromium picolinate could be effective in clomiphen citrate resistant PCOS patients. Objective: To compare the effects of chromium picolinate vs. metformin in clomiphen citrate resistant PCOS patients. Materials and Methods: The present randomized clinical trial was performed on 92 women with clomiphen citrate-resistant PCOS at the clinics which were affiliated to Shiraz University of Medical Sciences, Shiraz, Iran. The subjects were randomly assigned to two groups receiving either chromium picolinate (200g daily) or metformin (1500mg daily) for 3 months. Anthropometric and hormonal profile were measured and compared both before and after the treatment. Ovulation and pregnancy rate was measured in the two study groups, as well. Results: Chromium picolinate significantly decreased fasting blood sugar (FBS) after 3 months of treatment (p=0.042). In the same way, the serum levels of fasting insulin had significantly decreased leading to an increase in insulin sensi Continue reading >>

Chromium And Metformin Together? Is It Allowed?

Chromium And Metformin Together? Is It Allowed?

Chromium AND Metformin together? Is it allowed? I have a question. I am on metformin (the generic one) 500 mgs 3 x per day for a total of 1,500 mgs per day. I also take 100 mgs of Aldactone in the morning. My question is, do any of you fellow cysters know if it is safe to take Metforim AND Chromium together? I have been on Metformin since the end of March of this year and was on 50 mgs of the Aldactone until my doctor also increased that to 100 mgs at the end of March (the same time I began taking the metformin). I'm wondering the same thing as well. I just did a search on chromium in this forum and came up with all kinds of interesting and sometimes conflicting reports, including whether it should or shouldn't be taken at all I remember years ago before I even heard of PCOS, I tried chromium picolinate for weight-loss. Not only did it make my heart race, but it made my blood-sugar drop. I called the 800 number on the bottle, and I remember the rep telling me that if I had problems with hypoglycemia, not to take it. So yesterday I go to Walmart trying to find "pure" chromium, rather than the picolinate kind. I buy this stuff called "Chromium Blend". It has 400 mcgs of chromium picolinate, 200 mcgs of biotin, and 46mg of calcium. I took one this morning - so far no problems, but I'm kind of scared to take another one as I'm remembering what happened years ago. But I keep thinking that because I've been on metformin for 2 years now, my IR is under better control, and I won't have those same crazy reactions. I might try one more tomorrow to see what happens. Now I'm interested in the GTF type of chromium. I'll have to do a bit of online research, before I dive into that one though. Cool - glad your doctor was open-minded about. Also good that he's monitoring liver functio Continue reading >>

Role Of Chromium In Human Health And In Diabetes

Role Of Chromium In Human Health And In Diabetes

Despite widespread use by patients with diabetes and anecdotal reports in the past regarding its efficacy, until recently, data in humans concerning chromium’s effects on insulin action in vivo or on cellular aspects of insulin action were scarce. Consequently, significant controversy still exists regarding the effect of chromium supplementation on parameters assessing human health. Furthermore, elucidating the cellular and molecular mechanisms by which chromium supplements affect carbohydrate metabolism in vivo is necessary before specific recommendations can be made regarding its routine use in the management of diabetes. This review focuses on providing current information about this trace mineral’s specific mechanisms of action and clinical trials in patients with diabetes. Chromium, one of the most common elements in the earth’s crust and seawater, exists in our environment in several oxidation states, principally as metallic (Cr0), trivalent (+3), and hexavalent (+6) chromium. The latter is largely synthesized by the oxidation of the more common and naturally occurring trivalent chromium and is highly toxic. Trivalent chromium, found in most foods and nutrient supplements, is an essential nutrient with very low toxicity. The interest in chromium as a nutritional enhancement to glucose metabolism can be traced back to the 1950s, when it was suggested that brewer’s yeast contained a glucose tolerance factor (GTF) that prevented diabetes in experimental animals (1). This factor was eventually suggested to be a biologically active form of trivalent chromium that could substantially lower plasma glucose levels in diabetic mice (2). Interest regarding chromium administration in patients with diabetes was kindled by the observation in the 1970s that it truly was Continue reading >>

Chromium: Uses, Side Effects, Interactions, Dosage, And Warning

Chromium: Uses, Side Effects, Interactions, Dosage, And Warning

Chromium is a mineral. It is called an "essential trace element" because very small amounts of chromium are necessary for human health. There are two forms of chromium: trivalent chromium and hexavalent chromium. The first is found in foods and supplements and is safe for humans. The second is a known toxin that can cause skin problems and lung cancer . Some people try chromium for body conditioning including weight loss , increasing muscle, and decreasing body fat. Chromium is also used to improve athletic performance, to increase energy, and to prevent age-related mental decline. Chromium is used intravenously (by IV) as a supplement in nutritional IV drips. Chromium deficiency. Taking chromium by mouth is effective for preventing chromium deficiency. Diabetes. Some evidence shows that taking chromium picolinate (a chemical compound that contains chromium) by mouth, either alone or along with biotin, can lower fasting blood sugar, lower insulin levels, and help insulin work in people with type 2 diabetes . Also, chromium picolinate might decrease weight gain and fat accumulation in people with type 2 diabetes who are taking a class of antidiabetes medications called sulfonylureas. Higher chromium doses might be more effective and work more quickly. Higher doses might also lower the level of certain blood fats (cholesterol and triglycerides) in some people. Early research suggests that chromium picolinate might have the same benefits in people with type 1 diabetes, people who have diabetes as a result of steroid treatment, and people with diabetes the develops during pregnancy. However, researchers are looking carefully at the results that show chromium might be effective for treating diabetes. It might not help everyone. Some researchers think that chromium supplemen Continue reading >>

Pilot Trial of Chromium-Metformin Combination in Type 2 Diabetes The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. ClinicalTrials.gov Identifier: NCT00332085 Recruitment Status : Terminated (Issues w/recruitment) Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information This pilot trial seeks to gather preliminary data on the combination of chromium picolinate, the most commonly used form of chromium, and metformin. The trial will recruit type 2 diabetes subjects already on metformin and treat them with chromium for 8 weeks. The results of this trial will provide vital preliminary data including safety and size of effect to direct future studies. Chromium is widely marketed for use in diabetes and is used as a dietary supplement by approximately 10 million US consumers, second only to calcium supplementation. Limited scientific research has supported the potential of chromium to be beneficial in diabetes to improve blood sugar control and insulin sensitivity, yet many of these studies have design flaws and the relevance of the research in the US population has been questioned. Research on use of complementary & alternative medicine (CAM) suggests as many as 40% use CAM in combination with conventional medicine. Research performed at the Bastyr Center for Natural Health suggests 69% of patients get chromium as part of their treatment and 45% are on oral medications for blood sugar control.

Should I Try Chromium Tablets?

Should I Try Chromium Tablets?

I take metformin twice a day and, after breakfast, six or seven supplements I've seen mentioned on TV. Now I've ordered chromium GTF because it's reported to help with blood glucose control. Would you recommend these tablets, especially for those who have heart disease, as I do? John T. Foster, Jr., Jacksonville, Florida Chromium is an essential trace element that is associated with carbohydrate and lipid (fat) metabolism. Chromium is sometimes referred to as "glucose tolerance factor" (GTF), but GTF is actually a complex of various compounds, of which chromium is thought to be the active component. Some evidence shows that taking chromium picolinate can decrease blood glucose, insulin levels, and A1C and increase insulin sensitivity in people with type 2 diabetes . But not all the evidence is positive, and some studies have been inconclusive because of their small size or other factors. There is wide interest among people with diabetes about the role of various dietary supplements, herbs, and other "natural" products that may influence blood glucose levels and diabetic control. However, use of such products is largely a case of "buyer beware." This is primarily a result of a law enacted in 1994 called the Dietary Supplement Health and Education Act (DSHEA). David Kessler, a former commissioner of the Food and Drug Administration (FDA), has said that DSHEA "does not require that dietary supplements be shown [by manufacturers] to be safe or effective before they are marketed. The FDA does not scrutinize a dietary supplement before it enters the marketplace." In other words, the law lets manufacturers market herbal products without having proved their safety and efficacy. The FDA can only remove such products from the market later if problems happen to be detected. Contr Continue reading >>
