Chromium, an essential mineral found in meat, cheese and whole grains, is also available as a supplement in a few different forms, including chromium picolinate. Although sometimes advertised as a way to increase your weight loss, evidence doesn't appear to support this use. Speak to your physician before adding a supplement to your diet.
MedlinePlus notes that using chromium picolinate supplements for about three months may help you lose slightly more than 2 pounds. This isn't much, as you can safely lose up to 2 pounds per week with a reduced-calorie diet and exercise. A study published in March 2007 in "Nutrition" found that women who took 200 micrograms of chromium picolinate per day for 12 weeks didn't lose any more weight than those who followed a similar diet without taking these supplements. Another study, published in the "Journal of Alternative and Complementary Medicine in March 2010, found no weight-loss benefits for men taking 1,000 micrograms of chromium picolinate per day for 24 weeks.
