Chromium is a blue-white metallic element found naturally just in mix and utilized especially in alloys and in electroplating. [1]


Chromium was discovered by louis-nicholas vauquelin while try out a material known as siberian red lead, likewise called the mineral crocoite (pbcro4), in 1797. He produced chromium oxide (cro3) by mixing crocoite with hydrochloric acid (hcl). Although he thought a method for separating chromium didn’t yet exist, vauquelin was happily amazed in 1798 to find that he had the ability to get metal chromium by merely heating chromium oxide in a charcoal oven. Today, chromium is primarily acquired by heating up the mineral chromite (fecr2o4) in the existence of aluminum or silicon.

Chromium is a blue-white metal that is hard, brittle and very corrosion resistant. Chromium can be polished to form an extremely glossy surface area and is often plated to other metals to form a protective and appealing covering. Chromium is added to steel to harden it and to form stainless-steel, a steel alloy which contains at least 10% chromium. Other chromium-steel alloys are used to make armor plate, safes, ball bearings and cutting tools.

Chromium forms lots of vibrant compounds that have industrial uses. Lead chromate (pbcro4), also called chrome yellow, has been utilized as a yellow pigment in paints. Chromic oxide (cr2o3), likewise referred to as chrome green, is the ninth most plentiful substance in the earth’s crust and is a widely used green pigment. Rubies and emeralds likewise owe their colors to chromium substances. Potassium dichromate (k2cr2o7) is utilized in the tanning of leather while other chromium compounds are utilized as mordants, materials which completely repair dyes to materials. Chromium compounds are likewise used to anodize aluminum, a procedure which coats aluminum with a thick, protective layer of oxide. Chromite, chromium’s primary ore, is utilized to make molds for the shooting of bricks because of its high melting point, moderate thermal growth and stable crystal structure.

  • Estimated crustal abundance: 1.02 × 102 milligrams per kilogram
  • Estimated oceanic abundance: 3 × 10-4 milligrams per liter
  • Variety of stable isotopes: 3 (view all isotope data)
  • Ionization energy: 6.767 ev
  • Oxidation states: +6, +3, +2 [2]

Natural abundance

Chromium is discovered mainly in chromite. This ore is found in lots of places including south africa, india, kazakhstan and turkey. Chromium metal is normally produced by decreasing chromite with carbon in an electric-arc heating system, or lowering chromium( iii) oxide with aluminium or silicon. [3]


It may enhance blood glucose

In healthy people, the hormonal agent insulin has an important role in indicating the body to bring blood sugar level into the cells of the body.

In people with diabetes, there are issues with the body’s regular response to insulin.

Several research studies have actually suggested that taking chromium supplements can improve blood sugar for those with diabetes.

One study found that 16 weeks of 200 μg/ day of chromium was able to lower blood sugar level and insulin while improving the body’s reaction to insulin.

Other research study has shown that those with higher blood glucose and lower insulin sensitivity might react much better to chromium supplements.

Furthermore, in a big research study of over 62,000 adults, the probability of having diabetes was 27% lower in those who took dietary supplements including chromium.

Nevertheless, other research studies of 3 or more months of chromium supplementation have actually not shown enhanced blood sugar level in grownups with type 2 diabetes.

What’s more, research study in overweight adults without diabetes found that 1,000 μg/ day of chromium picolinate did not enhance the body’s action to insulin.

In fact, a large examination of 425 healthy individuals found that chromium supplements did not modify sugar or insulin levels.

Overall, some advantages of taking these supplements have been seen in those with diabetes but not in every circumstances.


For those with diabetes, chromium supplements may work at enhancing the body’s reaction to insulin or reducing blood glucose. Nevertheless, the results have been blended, and these advantages have actually not normally been observed in those without diabetes.

It may lower hunger and cravings

The majority of people who have actually tried to slim down and keep it off recognize with feelings of appetite and strong food yearnings.

As a result, many have an interest in foods, supplements or medications that could assist combat these urges.

A number of research studies have actually analyzed whether chromium picolinate might work in this capability.

In an 8-week research study, 1,000 μg/ day of chromium (in the form of chromium picolinate) minimized food consumption, cravings and cravings in healthy obese women.

The researchers reported that the results of chromium on the brain might have produced these effects.

Other research has actually taken a look at individuals with binge-eating disorder or anxiety, as these groups might possibly benefit the most from suppressing cravings or appetite.

An 8-week research study assigned 113 individuals with anxiety to receive either 600 μg/ day of chromium in the form of chromium picolinate or a placebo.

The researchers found that cravings and cravings were minimized with chromium picolinate supplements, compared to the placebo.

In addition, a little study observed possible benefits in individuals struggling with binge-eating disorder.

Specifically, doses of 600 to 1,000 μg/ day may have resulted in decreases in the frequency of binge eating episodes and signs of anxiety.


Although restricted proof is available, some reports indicate that 600 to 1,000 μg/ day of chromium picolinate may help in reducing hunger, cravings and binge consuming in some individuals.

Does it help you drop weight?

Due to chromium’s function in nutrient metabolism and possible results on eating habits, numerous research studies have analyzed whether it is a reliable weight reduction supplement.

One large analysis took a look at 9 different research studies consisting of 622 overweight or obese individuals to get a total picture of whether this mineral is useful for weight reduction.

Doses of approximately 1,000 μg/ day of chromium picolinate were utilized in these studies.

In general, this research found that chromium picolinate produced extremely percentages of weight reduction (2.4 pounds or 1.1 kg) after 12 to 16 weeks in obese or overweight grownups.

However, the scientists concluded that the effect of this amount of weight loss was doubtful and that the efficiency of the supplement was still unclear.

Another in-depth analysis of offered research on chromium and weight loss pertained to a comparable conclusion.

After examining 11 various studies, the scientists found weight reduction of just 1.1 pounds (0.5 kg) with 8 to 26 weeks of chromium supplementation.

Various other studies in healthy adults have shown no effect of this supplement on body composition (body fat and lean mass), even when integrated with exercise.


Based upon existing evidence, chromium picolinate is not effective at producing significant weight-loss in overweight or obese people. It appears to be even less reliable in normal-weight people, even when integrated with exercise.

Food sources

Although chromium picolinate is normally found in dietary supplements, lots of foods include the mineral chromium.

However, it is necessary to note that the agricultural and the production processes impact how much chromium is in foods.

Because of this, the actual chromium material of a specific food can vary, and there is no reliable database of the chromium material of foods. Additionally, while various foods contain this mineral, the majority of contain very percentages (1– 2 μg per serving).

In the united states, the suggested dietary referral intake (dri) of chromium is 35 μg/ day for adult guys and 25 μg/ day for adult ladies.

After the age of 50, the recommended intake decreases slightly to 30 μg/ day for men and 20 μg/ day for females.

Yet it’s important to keep in mind that these recommendations were developed using quotes of average consumptions in particular populations. Because of this, they are relatively tentative.

Regardless of the unpredictability of the true chromium material of many foods and the tentative consumption suggestions, chromium deficiency seems really unusual.

In general, meat, whole-grain items and some fruits and vegetables are considered great sources of chromium.

Some research has actually reported that broccoli is high in chromium, with approximately 11 μg per 1/2 cup, while oranges and apples may contain roughly 6 μg per serving.

In general, taking in a balanced diet plan including a range of minimally processed foods may help you meet your chromium requirements.


Both the true chromium material of foods and the recommended consumption of this mineral are tentative. However, chromium is found in low levels in several foods, and shortage is uncommon.

Should you take chromium supplements?

Due to the essential functions of chromium in the body, many have actually wondered if consuming additional chromium as a dietary supplement is a health technique.

There is not a specific upper limit for chromium.

Many studies have actually analyzed the results of chromium on blood sugar control and weight reduction.

However, in addition to taking a look at possible advantages of a specific nutrient, it is likewise important to consider whether there are any risks to taking in too much.

The national academy of medicine typically sets a bearable upper consumption level (ul) for particular nutrients. Surpassing this level may lead to toxicity or other health problems.

However, due to restricted offered information, no ul has been set for chromium (20 ).

Security of chromium picolinate

In spite of the lack of an official ul, some researchers have actually questioned whether chromium picolinate, the type of the mineral often found in supplements, is actually safe.

Based upon how this type of chromium is processed in the body, damaging particles called hydroxyl radicals may be produced.

These molecules can harm your hereditary product (dna) and cause other issues.

Remarkably, although picolinate is a popular kind of chromium supplement, these unfavorable impacts in the body may only take place when this form is consumed.

In addition to these concerns, a case study reported serious kidney problems in a female who took 1,200 to 2,400 μg/ day of chromium picolinate for the purpose of weight loss.

Other isolated health problems have been associated with the consumption of this supplement. [4]

How can chromium aid with weight-loss?

There are people who workout and see little to no results. Your exercise program might not be the cause. There might be a deeper cause at the cellular level.

One common issue is insulin resistance. Insulin resistance can cause a prediabetic state and eventually type two diabetes. One of the significant causes is the lack of chromium in the diet.

A healthy diet plan always accompanies a workout program. It is excellent to be healthy. More importantly, it is essential to provide the nutrients your body requirements.

When the body has the correct dietary balance, it can perform at ideal levels. Great fuel helps to fix the muscles. It can likewise minimize hunger. Getting the appropriate nutrients might trigger the body to stop looking for food to fill deep space.

Chromium is one of the important nutrients that the body requires. Consuming healthy food is great. It is meaningless if the body is unable to utilize it for energy. Chromium has a particular job to do with this process.

When we consume our digestive system turns the food into glucose. The glucose is the main fuel source of every cell in our bodies. Once it is broken down, it is then sent into the blood stream to feed our cells.

The pancreas produces insulin to assist the cells soak up the glucose. The job of insulin is to get the glucose out of the blood stream inside the cell. More glucose in the bloodstream increases the amount of insulin required to process it. Insulin spikes take place whenever we eat to control the quantity of glucose in our flowing through the blood.

Excessive glucose in the blood can trigger damage to the blood vessels. It causes oxidative stress. This kind of damage may lead to atherosclerosis. It is the reason that persons with diabetes are at an increased risk of heart problem and stroke.

Excess circulatory glucose may also harm nerves. It is the factor that individuals with unchecked diabetes experiences neuropathy. The glucose cuts off the capability nerves’ capability to send out signals.

Insulin and chromium deal with other aspects to prevent such damage. They both must work correctly to prevent the destruction that complimentary glucose may cause. They depend upon each other to get the job done.

Once the glucose lines up with a cell, it waits to go into. The insulin occurs and opens the door so that the glucose can get in. It is at this minute that chromium goes to work.

Chromium binds to the glucose transporter and pushes the glucose into the door. If there is no chromium or not enough in the body, the glucose simply continues to sit at the door. It drifts around the bloodstream waiting to get in. The body will ultimately downgrade the receptor.

When more food is consumed, more glucose is made. The problem is intensified. The body thinks it does not have sufficient insulin to unlock for the glucose. The pancreas receives the signal. It makes more.

The increase of insulin in the blood stream sends a signal that increases the need for more glucose. The individual craves sugar to correct the balance. When more sugar is eaten, more insulin is produced.

It is a vicious circle. Insulin resistance is a relentless issue with little to no signs. It may take a long time prior to the person knows there is a problem.

The excess insulin in the body carries out another task. If the quantity of glucose is not reduced by its existence, insulin instructs the body to save it as fat. It is insulin that keeps watch over the fat storage and signals when to release it.

The correct amount of chromium in the body may avoid this vicious cycle from the beginning. If chromium were readily available, then the insulin would open the door and chromium would assist in accompanying it inside. There the glucose would sustain the cells the way it was created.

The insulin would minimize in the blood stream since the glucose level would hang back to regular. The craving for sugar and carbs would diminish, and weight reduction might occur. [5]

How much chromium do our bodies frequently require?

The sufficient intake (ai) of chromium, or the advised level that healthy people ought to consume usually, varies from about 20 to 45 micrograms (mcg) each day for adults, keeps in mind torey armul, rd, a representative for the academy of nutrition and dietetics. “but there’s insufficient recognized research study to set an advised day-to-day allowance for it,” she states. The daily ai for chromium, which is figured out by the national academies of sciences, engineering, and medicine, differs, depending upon age and gender.

  • Babies ages 0 to 13 months: 2 to 5.5 mcg (micrograms)
  • Kid ages 1 to 3 years: 11 mcg
  • Kids ages 4 to 8 years: 15 mcg
  • Boys ages 9 to 18 years: 25 to 35 mcg
  • Girls ages 9 to 18 years: 21 to 24 mcg
  • Guy 19 to 50 years: 35 mcg
  • Ladies 19 to 50 years: 25 mcg
  • Male over 50: 30 mcg
  • Women over 50: 20 mcg

According to the national institutes of health, adult ladies, typically, consume 23 to 29 mcg of chromium a day, which typically satisfies their ai. However, if you’re pregnant or breastfeeding, your average consumption of chromium ought to be between 30 and 45 mcg a day. Adult guys, on the other hand, get more than their ai for this nutrient, balancing 39 to 54 mcg a day.

Excessive chromium (more than 40 mcg a day) isn’t necessary– the body can’t process it efficiently. “with dietary consumptions at this higher level, chromium absorption plateaus and urinary excretion increases,” states majumdar. Excretion of the mineral also increases with difficult exercise, the existence of infection, pregnancy, lactation, and with an increase in the consumption of easy sugars, she adds.

In the same way that inadequate proof prevents the setting of an advised dietary allowance for this nutrient, there isn’t a bearable ceiling (ul) for chromium, reports king. In fact, there are few negative effects linked to high chromium consumption, includes armul. “chromium toxicity tends to be rather uncommon among those taking it and any associated dangers are seen in commercial settings,” discusses king. Chromium is found in both a biologic type in food (trivalent or chromium 3+) and hexavalent (chromium 6+), which is the harmful version produced by industrial contamination.

What are the symptoms of chromium shortage?

Taking in too little chromium can lead to a variety of signs, including some that mimic those of diabetes, such as weight loss, impaired glucose tolerance, neuropathy, anxiety, tiredness and muscle weak point, explains majumdar. Fortunately, chromium shortage is extremely uncommon and has mainly been documented in people who are fed through dietary support. To address this shortage, chromium has been added to intravenous (iv) solutions, she adds.

” there’s some idea that the elderly might need more chromium in their everyday diets, however presently this is just a hypothesis,” states king. It’s difficult to identify who may be at risk for insufficient chromium as there isn’t a reliable lab test of biochemical markers that determine the body’s stores. “it’s hard to gauge this mineral in people because blood levels aren’t reflective of true amounts since the body has its own chromium storage,” states majumdar. Chromium is saved in the liver, spleen, soft tissue, and bones. (1 ).

Foods that are naturally rich in chromium

The primary factor chromium shortage is so uncommon is that this nutrient is discovered in an abundance of fruits, vegetables, grains, and meat– and even in wine. Good sources of chromium include broccoli, green beans, potatoes, apples, bananas, entire grains, peas, cheese, corn, grapes, beef, and poultry. “you can also get chromium from garlic, basil, turkey, sweet potatoes, english muffins, and waffles,” notes king. For the most focused food source of chromium, seek to maker’s yeast (1 tablespoon contains as much as 60 mcg), adds majumdar.

Diets that are high in simple sugars– in which easy sugars make up more than 35 percent of calorie intake– can minimize absorption of chromium. Because the absorption of chromium from the intestines is small, you might attempt to enhance this process by targeting the way you consume. Fruits and vegetables with vitamin c and niacin, a b vitamin found in meat, poultry, fish, and grains, can enhance chromium absorption. [6]

Chromium adverse effects

Chromium is likely safe for short-term oral supplementation in a day-to-day dosage of as much as 1,000 mcg (1 mg). Possible side effects are moderate and include:.

  1. Headaches
  2. Sleep disruptions
  3. Irritability and mood modifications

It is safe children and pregnant females in the amounts typically present in food. Supplements with higher quantities might also be safe in these sensitive groups, but they need to use them under strict medical guidance. [7]
There are couple of recognized adverse effects of chromium supplements. In reasonable dosages, there does not seem any issue for severe negative effects.

Nevertheless, there have been isolated reports of negative adverse effects when chromium is taken in big dosages. Diarrhea, headaches, hives, and vertigo, have actually been revealed to occur when the supplement is taken in dosages of in between 1,200 and 2,400 micrograms (mcg) daily for four months. [8]

Special precautions and warnings

Pregnancy: chromium is most likely safe when taken by mouth in quantities that do not go beyond appropriate intake (ai) levels. The ai for those 14-18 years old is 28 mcg daily. For those 19-50 years old, it is 30 mcg daily. Chromium is perhaps safe to use in quantities higher than the ai levels while pregnant. However don’t take chromium supplements during pregnancy unless advised to do so by a doctor.

Breast-feeding: chromium is most likely safe when taken by mouth in amounts that do not go beyond ai levels. The ai for those 14-18 years of ages is 44 mcg daily. For those 19-50 years of ages, it is 45 mcg daily. There isn’t adequate trustworthy information to understand if taking greater quantities of chromium is safe when breast-feeding. Remain on the safe side and stick to quantities listed below the ai.

Children: chromium is most likely safe when taken by mouth in quantities that do not go beyond ai levels. For those 0-6 months old, it is 0.2 mcg; for those 7-12 months old, it is 5.5 mcg; for those 1-3 years old, it is 11 mcg; for those 4-8 years old, it is 15 mcg. For males 9-13 years of ages, it is 25 mcg; for males 14-18 years of ages, it is 35 mcg. For women 9-13 years of ages, it is 21 mcg; for women 14-18 years of ages, it is 24 mcg. Taking chromium in quantities above the ai level is possibly safe for most children.

Behavioral or psychiatric conditions such as anxiety, stress and anxiety, or schizophrenia: chromium might impact brain chemistry and might make behavioral or psychiatric conditions even worse. [9]


Chromium is an important mineral, taken in through the diet plan. It is discovered in trace quantities in plant items, specifically grains.

Chromium manages insulin in the body. It is in some cases supplemented to improve insulin action in the body.

When chromium is supplemented by individuals with normal or raised chromium levels, no reliable result is achieved. Besides a moderate reduction in fasting glucose, no diabetes-related biomarkers are improved.

People with a subclinical chromium deficiency (listed below optimal, however not a true deficiency) may experience advantages when supplementing chromium, however more research study is needed to confirm this impact. Real chromium deficiencies, characterized by non-active chromodulin, are unusual.

Chromium’s main mechanism is directly tied to chromodulin. Chromodulin, a protein, generally augments the signaling of insulin receptors. If this protein is impaired, insulin’s ability to work in the body is considerably decreased.

Though chromium supplementation is ineffective for diabetics, taking chromium alongside a tested treatment may help fight anxiety and the snacking connected with binge eating. Additional research is needed to figure out chromium’s precise mechanism during these results. [10]
