Why supplement?
Inorganic selenate
Sodium selenate is hexavalent selenate; the metabolic starting point differs from sodium selenite, and it is likewise used only in micrograms. The use is as a trace raw material for selenium enzymes, not an antioxidant course.
GPx and deiodinases
Sodium selenate 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.
