While selenium occurs naturally in most foods, because of our modern agricultural practices, many of our foods are not as mineral rich as they used to be. For some of us that could mean selenium deficiency; look for these signs: weakness and pain in the muscles, discoloration of hair and skin, and whitening of the fingernail beds.
To increase your selenium levels naturally, try eating more button mushrooms, cod, shrimp, tuna, halibut, salmon, Brazil nuts, and sunflower seeds. Consuming too much selenium through food is not likely, with the exception of large consumption of Brazil nuts.
If you have signs of selenium deficiency, and before increasing your intake through a supplement, be sure to consult your holistic healthcare practitioner to ensure proper levels. Selenium toxicity can cause nausea, vomiting, hair loss, skin lesions, abnormalities in the beds of the fingernails, and fingernail loss.
