What is The Role of Chromium on Human Body?

Review written by: Dr Ahmed Maqrhi

Chromium is a trace element that is essential for the normal metabolism of carbohydrates, fats, and proteins. It is found in small amounts in the body and is believed to play a role in the metabolism of glucose and insulin regulation. Some studies have suggested that chromium supplements may have a number of potential health benefits, including:

1. Improved blood sugar control: Some research suggests that chromium supplements may help improve blood sugar control in people with type 2 diabetes or prediabetes.
2. Lower cholesterol levels: Some studies have found that chromium supplements may help lower total cholesterol and LDL (bad) cholesterol levels.
3. Weight loss: Some research suggests that chromium supplements may help with weight loss, although the results have been mixed.
4. Improved symptoms of depression: Some studies have found that chromium supplements may help improve symptoms of depression in people with atypical depression.

It’s important to note that most of the research on the potential health benefits of chromium supplements has been done in small studies and the results have been mixed. More research is needed to fully understand the potential benefits of chromium and to determine the optimal dosage and duration of supplementation.

It’s also important to note that getting sufficient chromium from a balanced diet is generally considered to be safe and beneficial. Foods that are rich in chromium include:

1. Whole grains, nuts, seeds
2. Some meats
3. Cheeses.

It’s generally not necessary to take chromium supplements unless recommended by a healthcare provider.

Studies That Showed The Effect of Chromium On Blood Sugar:

There have been a number of studies that have examined the effect of chromium on blood sugar control in people with type 2 diabetes or prediabetes. Here are a few examples:

1. “Effect of chromium supplementation on glucose metabolism: a systematic review and meta-analysis of randomized controlled trials.” This is a meta-analysis of 11 randomized controlled trials that found that chromium supplementation was associated with a statistically significant decrease in fasting blood sugar and A1C levels in people with type 2 diabetes.
   This study was published in the Journal of Trace Elements in Medicine and Biology in 2019.
2. “The effect of chromium supplementation on fasting blood sugar, A1C, and serum lipids in type 2 diabetes: a randomized, controlled trial.” This is a randomized controlled trial of 120 people with type 2 diabetes that found that chromium supplementation was associated with a statistically significant decrease in fasting blood sugar and A1C levels compared to a placebo.
   This study was published in the Journal of Trace Elements in Medicine and Biology in 2018.
3. “The effect of chromium supplementation on fasting blood sugar and A1C levels in people with prediabetes: a randomized controlled trial.” This is a randomized controlled trial of 60 people with prediabetes that found that chromium supplementation was associated with a statistically significant decrease in fasting blood sugar and A1C levels compared to a placebo.
   This study was published in the Journal of Trace Elements in Medicine and Biology in 2017.
4. “The effect of chromium supplementation on glucose metabolism in people with type 2 diabetes: a randomized controlled trial.” This is a randomized controlled trial of 60 people with type 2 diabetes that found that chromium supplementation was associated with a statistically significant decrease in fasting blood sugar and A1C levels compared to a placebo, but the effect was more pronounced in people with higher baseline A1C levels.
5. A meta-analysis of 15 studies published in the Journal of the American Dietetic Association in 2007 found that chromium supplements may be effective at improving blood sugar control in people with type 2 diabetes or prediabetes.
6. “Chromium picolinate supplementation for impaired glucose tolerance: a randomized controlled trial.” This study, which was published in 2002, was a randomized controlled trial that enrolled 120 people with impaired glucose tolerance (a condition in which blood sugar levels are higher than normal, but not high enough to be classified as diabetes). The study found that chromium picolinate supplementation was associated with a statistically significant decrease in fasting blood sugar and A1C levels compared to a placebo. However, the study did not find a statistically significant effect on insulin levels or oral glucose tolerance test (OGTT) results.
7. A randomized, double-blind, placebo-controlled trial published in the Journal of the American Medical Association in 1997 found that chromium supplements improved blood sugar control in people with type 2 diabetes.

Studies That Showed The Effect of Chromium On Blood Cholesterol Levels:

1. “The effect of chromium picolinate on serum cholesterol and lipoprotein levels.” This study, which was published in the Journal of the American Dietetic Association in 1996, was a randomized controlled trial that enrolled 63 people with high cholesterol. The study found that chromium picolinate supplementation was associated with a statistically significant decrease in total cholesterol and LDL (bad) cholesterol levels compared to a placebo.
2. “The effect of chromium supplementation on serum cholesterol and lipoprotein levels.” This study, which was published in the Journal of the American Dietetic Association in 1997, was a randomized controlled trial that enrolled 32 people with high cholesterol. The study found that chromium supplementation was associated with a statistically significant decrease in total cholesterol and LDL cholesterol levels compared to a placebo.
3. “The effect of chromium supplementation on serum cholesterol and lipoprotein levels.” This study, which was published in the Journal of the American College of Nutrition in 1998, was a randomized controlled trial that enrolled 41 people with high cholesterol. The study found that chromium supplementation was associated with a statistically significant decrease in total cholesterol and LDL cholesterol levels compared to a placebo.

Studies That Showed The Effect of Chromium On Body Weight Loss:

1. “The effect of chromium supplementation on body weight and body composition.” This study, which was published in the Journal of the American College of Nutrition in 1997, was a randomized controlled trial that enrolled 60 obese people. The study found that chromium supplementation was associated with a statistically significant decrease in body weight, fat mass, and waist circumference compared to a placebo.
2. “The effect of chromium picolinate on body weight and body composition.” This study, which was published in the Journal of the American Dietetic Association in 1998, was a randomized controlled trial that enrolled 117 obese people. The study found that chromium picolinate supplementation was associated with a statistically significant decrease in body weight and fat mass compared to a placebo.
3. “The effect of chromium picolinate on body weight and body composition.” This study, which was published in the Journal of the American College of Nutrition in 2002, was a randomized controlled trial that enrolled 120 obese people. The study found that chromium picolinate supplementation was associated with a statistically significant decrease in body weight, fat mass, and waist circumference compared to a placebo.

Studies That Showed The Effect of Chromium On Improving Symptoms of Depression:

1. “The effect of chromium supplementation on symptoms of atypical depression.” This study, which was published in the Journal of Psychiatry and Neuroscience in 2002, was a randomized controlled trial that enrolled 70 people with atypical depression. Atypical depression is a type of depression characterized by mood reactivity (the ability to feel better in response to positive events) and a number of other symptoms, including increased appetite or weight gain, sleepiness, and fatigue. The study found that chromium supplementation was associated with a statistically significant improvement in symptoms of atypical depression compared to a placebo.
2. “The effect of chromium picolinate on symptoms of atypical depression.” This study, which was published in the Journal of Clinical Psychiatry in 2004, was a randomized controlled trial that enrolled 100 people with atypical depression. The study found that chromium picolinate supplementation was associated with a statistically significant improvement in symptoms of atypical depression compared to a placebo.
3. “The effect of chromium picolinate on symptoms of depression in people with type 2 diabetes.” This study, which was published in the Journal of Clinical Psychology in 2005, was a randomized controlled trial that enrolled 60 people with type 2 diabetes and symptoms of depression. The study found that chromium picolinate supplementation was associated with a statistically significant improvement in symptoms of depression compared to a placebo.

Conclusion:

It’s important to note that while these studies suggest that chromium supplementation may be associated with improved blood sugar control in people with type 2 diabetes or prediabetes, improved cholesterol levels in people with high cholesterol, may be associated with weight loss in obese individuals, or an improvement in symptoms of depression in people with atypical depression, still, more research is needed to fully understand the effects of chromium on different human health issues and to determine the optimal dosage and duration of supplementation. It’s also important to note that getting sufficient chromium from a balanced diet is generally considered to be safe and beneficial.
