Why supplement?
Selenium-enriched yeast
Organic selenium complex builds selenium into yeast protein as a mixture of selenoamino acids. People sensitive to yeast should avoid it. Dose still by micrograms of selenium; it is not a protein supplement.
GPx and deiodinases
Organic selenium complex is a source of selenium. Selenocysteine sits in antioxidant enzymes and thyroid deiodinases. This form is counted in micrograms; one serving of Brazil nuts can already be too much.
How to take it
Avoid using several selenium-containing products at the same time.
How oftenUse according to daily need; long-term self-exceeding of the upper limit is not recommended.
What to watch
Cautions
Excess selenium can be toxic; count Brazil nuts and multivitamins toward the total.
People with thyroid disease should not replace treatment with selenium on their own.
· Garlic breath
· Metallic taste or stomach upset (excess)
· Chronic excess can cause hair loss, brittle nails, and neurologic changes.
Long-term dependenceNot addictive; long-term excess carries a risk of selenium toxicity.
