You may have heard of chromium supplements that claim to help with diabetes or weight loss. It is actually an essential mineral that our bodies need in very small amounts. However, there are different opinions about taking it as a supplement. So today we will talk about chromium, its supposed benefits, the foods we can get it naturally from, and the things to be aware of if you take it as a supplement.

Simply put, what is this Chromium?
Chromium is a mineral that our bodies need in trace amounts, that is, in very small amounts. The type of chromium that is particularly relevant to these health benefits we are talking about is the trivalent chromium.
The main function of chromium in our body is to enhance the function of the hormone insulin. Think of insulin as a vehicle that carries sugar (glucose) from our blood into our cells. Chromium is like a "little helper" that helps that vehicle and makes its job easier. This is why chromium is believed to help control blood sugar levels.
What are the benefits of chromium?
- Diabetes and Insulin Resistance: Some studies have shown that people with Type 2 Diabetes and a condition called Insulin Resistance may benefit from chromium supplements. Insulin resistance is a condition in which the body does not respond properly to the insulin it produces. There is evidence that chromium can lower blood glucose levels and increase insulin sensitivity. However, not all studies have confirmed this benefit . It may be most effective in people with a chromium deficiency. Chromium deficiency is rare in people who eat a healthy diet.
- Polycystic Ovary Syndrome (PCOS): PCOS is associated with insulin resistance, so some studies have found that chromium may provide some relief for women with PCOS.
- Weight loss and muscle growth: Some people use chromium supplements to help lose weight, burn unwanted fat, and build muscle. While some studies have shown some benefits, others have not. So it's not a magic bullet for weight loss .
The most important thing is that chromium is not a cure for diabetes, nor should it be used as a substitute. If you have diabetes, be sure to talk to your doctor before taking any supplements.
How much chromium do we need per day?
Experts can't say exactly how much chromium you need per day, so there's no Recommended Dietary Allowance (RDA). Instead, they've come up with a minimum daily intake (Adequate Intake - AI).
- Men ages 19-50: 35 micrograms (mcg)
- Women ages 19-50: 25 micrograms (mcg)
- Pregnant mothers: 30 micrograms (mcg)
- Nursing mothers: 45 micrograms (mcg)
A person who eats a well-balanced diet can easily get this amount. But remember, taking too much chromium is not good either . If taken in high doses, it can negatively affect insulin sensitivity and cause kidney or liver damage. In diabetes studies, doses between 200-1000 micrograms per day, divided into two or three times a day, have been used. But that is under medical supervision.
What natural foods are rich in chromium?
If you eat a balanced diet, you probably don't need chromium supplements. Chromium is a mineral that plants absorb from the soil, so it's found in vegetables, fruits, whole grains, and meat from animals that eat those grains or grass. The table below will give you a good idea of how much chromium you need.
| Food type | Description and chromium content |
|---|---|
| Mussels | There is a high amount of 128 micrograms per 100 grams. Shellfish like oysters and shrimp are also rich in chromium. |
| Broccoli | Although many vegetables contain chromium, a cup of cooked broccoli has a high content of 22 micrograms. |
| Grape Juice | A cup of grape juice contains about 7.5 micrograms. But remember to choose 100% grape juice with no added sugar. |
| Whole Wheat | Whole-grain breads and rotis made from atta flour contain chromium. For example, a whole-grain English muffin contains 3.6 micrograms. |
| Meats | A 3-ounce serving of beef contains 2 micrograms, turkey contains 1.7, and chicken contains about 0.5. Processed meats like ham and bacon also contain chromium, but eating them frequently increases the risk of developing other diseases. |
| Brazil Nuts | Each seed contains 1 microgram of chromium. However, since they are also high in the mineral selenium, it is not advisable to eat more than 5 seeds per day. |
What are the risks of taking chromium supplements?
If you're considering taking a chromium supplement, you should definitely be aware of these risks.
| Risk type | Description and things to consider |
|---|---|
| Side Effects | Serious side effects are generally rare, but some people have experienced irregular heartbeats, insomnia, headaches, mood swings, and allergic reactions. People with kidney or liver disease may be at increased risk of damage to these organs if they take chromium without medical advice. |
| Interactions with other drugs | Because chromium affects blood sugar levels, it is dangerous for someone taking diabetes medications such as insulin to take chromium unless under the supervision of a doctor. In addition, it can interact with medications such as antacids, corticosteroids, beta-blockers, thyroid medications, and NSAID pain relievers (e.g., ibuprofen) for gastritis. |
| Special Risks | Pregnant or breastfeeding mothers should not take chromium supplements without medical advice. And if you are giving it to young children , you should definitely ask a doctor. Some experts say that no one should take more than 200 micrograms per day without medical advice. |
