Chromium is a mineral that plays a key role in nutrient metabolism. It’s found naturally in a variety of foods, including broccoli, garlic, and potatoes (1, 2).

Many people take chromium as a supplement to help improve their blood sugar levels. Some research also suggests that it aids conditions like type 2 diabetes and metabolic syndrome, a group of symptoms that increases your risk of heart disease and diabetes (3).

Still, a quality supplement can be hard to find. Healthline evaluated chromium supplements based on the following criteria:

  • the type of chromium
  • the dosage
  • the presence of additional ingredients
  • the use of third-party testing and certification

Here are 10 of the best chromium supplements for 2021.

Unlike most other supplements on the market, this NOW Foods product contains chromium chelavite, a form that’s been shown to improve insulin sensitivity (8).

This means that it may help enhance your body’s ability to use insulin, the hormone responsible for carrying sugar from your blood to your cells (9).

Pure Encapsulations is certified by NSF International and GMP registered. The company exceeds the standards of United States Pharmacopeia (USP), an organization that evaluates the quality of dietary supplements.

Nature’s Sunshine Chromium GTF

Dose: 1 capsule contains 300 mcg of chromium

This potent supplement is made from two forms of chromium — chromium amino acid chelate and chromium nicotinate.

Chromium amino acid chelate is a type of chromium bound to an amino acid. Meanwhile, chromium nicotinate is bound to niacin.

While some animal studies indicate that pairing niacin with chromium is beneficial, additional research is needed on these forms’ benefits and absorption rates (11, 12, 13, 14).

Nature’s Sunshine is GMP-certified by NSF International. The company conducts hundreds of product tests to ensure quality.

Notably, each capsule boasts a proprietary blend of medicinal herbs, including red clover flowers, yarrow, and horsetail.

When selecting a chromium supplement, you should consider several factors.

First, be sure to check the ingredient list. Look for products without artificial ingredients, additives, and fillers.

You’ll also want to pay attention to the form. Chromium supplements are available in several forms, including:

  • chromium picolinate
  • chromium chloride
  • chromium nicotinate/polynicotinate
  • chromium chelavite
  • chromium citrate

Although some studies indicate that your body absorbs chromium picolinate best, there’s concern that this form may cause oxidative damage to your cells (15, 16, 17).

Certain supplements may also contain additional ingredients to enhance their potential health benefits, such as cinnamon or other medicinal herbs.

Furthermore, you should look for products that have undergone third-party testing, are certified by organizations like USP or NSF International, and are manufactured in GMP-certified facilities.

Finally, it’s important to check the product dosage carefully.

Although daily needs vary based on age and sex, the recommended Daily Value (DV) for chromium is 35 mcg. Yet, many supplements pack significantly higher amounts and are available in doses ranging from 200–1,000 mcg (2).

Currently, chromium has no established tolerable upper intake (UL), which is the highest amount of a nutrient you can take without risk of adverse health effects (2).

Nonetheless, chromium may interact with certain medications, including antacids, beta-blockers, proton pump inhibitors, insulin, and corticosteroids (2).

If you’re on these medications or have any underlying health conditions, consult a healthcare professional before taking chromium.

The numerous chromium supplements on the market vary in dosage and form.

Some contain added ingredients, such as cinnamon or other herbs and spices, some of which may amplify their potential benefits.

Keep in mind that all of the supplements listed above contain far more than the recommended DV of 35 mcg. If you’re concerned about proper dosage — or if you’re taking any other medications — be sure to consult your healthcare provider before taking chromium.

It’s also important to pair these supplements with a nutritious and balanced diet.
