Minerals - Selenium - Optimal Absorption

One brazil nut daily will generally provide you with your daily recommended intake. Ideal supplemental forms of selenium include selenomethionine, selenium-rich yeast, and selenium chelate.

Absorption of selenium is affected by heavy metals (lead, mercury, cadmium, et cetera) and possibly zinc and other trace minerals. Various chemotherapeutic drugs can interfere with selenium absorption. Commercial food processing also reduces selenium levels.

The following is a list of United States 1989 Recommended Daily Allowances (RDA) for minimum nutritional selenium intake and are included as a guideline only. These values are considered too low for most individuals, according to better nutrition authorities today. Consult with your nutritionist, naturopath, or other health practitioner for a dosage appropriate for your needs. Children under 6 years of age should be under the supervision of the above mentioned specialists if directly supplementing with selenium.
