Chromium (25 mcg): AI for women ages 19-50 is 25 mcg


  • Chromium enhances the action of insulin, the hormone that determines how your body uses and stores sugar or glucose
  • It is also directly involved in carbohydrate, fat, and protein metabolism itself.

Copper (900 mcg): RDA for women ages 19+ is 900 mcg


Iodine (150 mcg): RDA for women ages 19+ is 150 mcg




  • Iodine is needed to make the thyroid hormones thyroxine (T4) and triiodothyronine (T3). Thyroid hormones regulate many processes like protein synthesis, enzymatic activity, and metabolic activity

  • Thyroid hormones also help develop the skeletal and central nervous systems. If your body does not get enough iodine, then your thyroid gland will enlarge and cause a goiter.


Iron (18 mg): RDA for women ages 19-50 is 18 mg


  • Iron is mainly found in hemoglobin, a red blood cell protein that carries oxygen from your lungs to the rest of your body. It is also found in myoglobin, which carries oxygen directly to muscles
  • Women need to pay attention to their iron levels more so than men because they lose iron during menstruation. 


Manganese (1.8 mg): AI for women ages 19+ is 1.8 mg


  • Manganese is a cofactor for many enzymes that take part in the metabolism of glucose, cholesterol, and amino acids.
  • It is involved in reproduction, the immune response, and making bones. It also works with vitamin K for blood clotting.


Molybdenum (45 mcg): RDA for women ages 19+ is 45 mcg



Selenium (55 mcg): RDA for women ages 19+ is 55 mcg



  • Selenium makes up selenoproteins, which play critical roles in the body. They help with reproduction, DNA production, and thyroid hormone metabolism. 
  • It also helps protect your body from infections and damage caused by free radicals.



Zinc (8 mg): RDA for women ages 19+ is 8 mg



  • Zinc is required by about 100 different enzymes to work. It is needed by the immune system to defend against invaders as well as help wounds heal. 
  • It also plays a role in protein synthesis, DNA synthesis, cell division, taste, and smell.
