Chromium is a mineral that your body requires in trace amounts. It mainly occurs in two forms; hexavalent chromium and trivalent chromium. The former is a toxin, while the latter is safe for humans. However, the body doesn’t produce chromium on its own. Therefore, you should take it through chromium foods or supplements. It is one of the most commonly used dietary supplements, available in powder, capsule, and tablet form.
In addition to carbs, protein, and fats, trace minerals like chromium play a key role in your overall health. It helps in blood sugar management by transporting glucose from the bloodstream into the cells to be assimilated into energy. Furthermore, chromium metabolises macronutrients and serves as a natural treatment for depression. So now might be the time to double-check if you’re consuming adequate chromium or not.
Chromium is naturally present in specific food sources and the environment. The chromium mineral found in foods will not cause any harm to your body. Foods with 5 to 7 micrograms of chromium per serving are good enough to be considered a potent dietary source of this mineral. With the right food choices, you can supercharge your diet with chromium. Foods such as potatoes with skin, molasses, cheeses, whole-grain bread, and brewer’s yeast are easily available chromium sources.

Health Benefits of Chromium
Improves Blood Sugar
According to a study, consistent chromium intake improves the body’s response to insulin and lowers blood sugar levels. Those with diabetes can take chromium supplements to boost insulin sensitivity. In addition, if you’ve been on a chromium-enriched diet since childhood, you might be less likely to have diabetes risk.
Aids in Weight Loss
Intense food cravings are always the roadblock in the weight loss journey. It tempts you to binge eat or snack more on unhealthy carbs and calories. However, a study shows that chromium curbs cravings and hunger, reducing food intake. It might be due to the hunger-suppressing effect of chromium on the brain. Intake of around 600 to 1,000 μg/day of chromium positively impacts weight loss.
Due to its well-tolerated antidepressant properties, chromium can be the alternative treatment for depression and mood swings. The characteristics of atypical depression are hypersensitivity, carbohydrate craving, weight gain, and excessive sleep. When you take chromium, it ensures a constant supply of glucose to the brain. It helps the brain to function effectively and control depressive symptoms. Furthermore, chromium increases insulin sensitivity. Insulin influences the production of serotonin, a happy chemical that regulates moods and stimulates a feeling of calmness in people with depression.
Beneficial for PCOS
PCOS or polycystic ovary syndrome is a hormonal disorder marked by enlarged ovaries and irregular menstruation. Insulin resistance is the most common trouble during PCOS. A study ascertains that you can use chromium in nutritional therapy for PCOS. It increases insulin sensitivity and decreases the risk of diabetes in PCOS women. The best part is that Chromium has the potential to show long-term benefits. A daily dose of 1000 μg chromium is sufficient to bring back the regular menstrual cycle.
Possible Downsides of Chromium
Chromium has no known severe drug interactions. However, it may show mild to moderate interactions with at least 45 different drugs. For example, certain antacids may interfere with the absorption of chromium supplements. Other drug interactions and possible side effects include:
- Acetaminophen: Reduces the excretion rate of chromium resulting in higher serum levels.
- Acetazolamide: Increases chromium’s excretion rate, leading to lower serum levels and minimal benefits from the mineral.
- Metformin: Taking chromium along with metformin might cause blood sugar to drop too low.
- Benadryl: Interactions between Benadryl and chromium leads to fatigue, pain, migraine, and atrial fibrillation.
Chromium may not be a good idea if you have the following medical conditions.
- Severe diabetes
- Thyroid disorders
- Kidney disease
- Liver disease
- People under steroid therapy or medication
If people with an existing liver condition take chromium, it may increase the likelihood of liver damage. Similarly, chromium tends to cause thyroid dysfunction if the gland is already under a medical abnormality. To be specific, it impairs the absorption of thyroid medications and slows down the recovery process.
Caution during Pregnancy and Lactation
There is no definite supportive claim that chromium supplement is safe during lactation or pregnancy. Pregnant and breastfeeding women must not take additional chromium without medical advice as the mineral may pass to the child through breast milk. Moreover, too much chromium exposure may be toxic for foetal growth during early and mid-pregnancy. However, dietary intake of chromium during this phase does not possess detrimental effects.
Other Side Effects
Some people have reported occasional side effects like headaches, allergic reactions, sleep disturbances, and mood changes. If you experience irregular heartbeats, seek immediate medical attention and discontinue chromium intake.
Taking too little chromium leads to chromium deficiency resulting in a range of symptoms. Diets high in simple sugars tend to reduce chromium absorption, leading to its deficiency. It is hard to analyse how much chromium is lacking in an individual since the blood levels don’t reflect the proper levels of chromium. A person with chromium deficiency experiences symptoms similar to diabetes. The commonly reported symptoms are muscle weakness, general fatigue, anxiety, impaired glucose tolerance, and weight loss.
Fortunately, chromium deficiency is easily reversible through diet changes. In severe cases, chromium deficiency is approached by intravenous (IV) formulations of the mineral. Some might feel they should take supplements to address this mineral shortfall. However, taking chromium supplements is not necessary. Instead, the prime focus will be on chromium-rich foods that offer additional benefits. Unlike supplements, consuming too much chromium from dietary sources is unlikely. Thus, stick to high chromium foods during deficiency.
Recommended Daily Intake
The recommended dietary allowance of chromium differs with age, gender, pregnancy, and lactation. Acute overdose of chromium is rare but try to keep its intake as recommended. You may need an additional chromium dose depending on the health conditions like PCOS and insulin resistance but refrain from doing it without a doctor’s consultation. There is no upper tolerance limit set for chromium. Hence, stick to adequate intake levels to reap the maximum benefits.
Recommended daily intake for people of different ages are:
- Infants aged 0 to 13 months: 2 to 5.5mcg
- Children aged 1 to 3 years: 11mcg
- Children aged 4 to 8 years: 15mcg
- Boys aged 9 to 18 years: 25 to 35mcg
- Girls aged 9 to 18 years: 21 to 24mcg
- Men aged 19 to 50 years: 35mcg
- Women aged 19 to 50 years: 25mcg
- Men over 50: 30mcg
- Women over 50: 20mcg
Chromium is a trace mineral, meaning that our bodies need it in small amounts. Even though the requirement of chromium is in fewer quantities, it can still impact your overall health. This vital mineral ensures that the food you eat is correctly converted into energy. Also, chromium aids in weight loss, hunger management, and lowering blood sugar levels. Reliable sources have stated that chromium is highly beneficial for women suffering from PCOS. It regularises the menstrual cycle and brings back the hormones in control. However, chromium supplements may interact with certain medications like any other supplement. People with kidney conditions, thyroid problems, and liver disease should avoid chromium.
Animal-based proteins like turkey breast are an excellent source of chromium. You can also find it in whole wheat flour, brewer’s yeast, string beans, tomato juice, and broccoli. Apart from broccoli, grape juice provides a concentrated source of chromium. Depending on age and gender, there is a different intake value for chromium. Specifically, women between 19 to 50 need about 25 mcg of chromium every day. Men of the same age group require 35 mcg. Children and adolescents also need chromium but in lesser quantities. Follow the recommended intake range to prevent any deficiency or overdose.
