Mason Selenium 200mcg tablets provide a supplemental dose of the essential trace mineral selenium in a convenient tablet form. This high-quality selenium supplement supports antioxidant protection, thyroid function, immune health, and overall wellness. Mason Selenium is formulated to help maintain optimal levels of this vital micronutrient that many diets may lack in sufficient quantities.
Uses
Mason Selenium tablets help maintain optimal selenium levels in the body to support thyroid hormone activity, reproductive health, DNA production, and eyesight preservation. This supplement assists in maintaining proper immune response, protects cells from oxidative damage, and helps reduce inflammation. Mason Selenium is particularly beneficial for individuals with limited dietary selenium intake or increased needs.

How It Works
As a component of glutathione peroxidase and other selenoproteins, selenium acts as an antioxidant to prevent cellular damage from free radicals. It supports the conversion of T4 to the active thyroid hormone T3, enabling proper metabolic function. Selenium also enhances immune cell activity, particularly natural killer cells, and supports DNA repair mechanisms to maintain cellular integrity.
Duration of Action
Mason Selenium begins incorporation into the body’s selenium pool within hours of consumption. Selenoproteins may show increased activity within 2-3 days of supplementation. Optimal selenium status in previously deficient individuals typically develops after 8-12 weeks of consistent supplementation. Benefits to immune function and antioxidant protection may be noticeable after 4-6 weeks of regular use.

Side Effects
Mason Selenium at the recommended dosage is typically well-tolerated. Occasional mild digestive discomfort may occur but usually resolves with continued use. At appropriate doses, serious side effects are rare. However, excessive selenium intake over extended periods could potentially lead to selenosis, characterized by brittle nails, hair loss, and gastrointestinal upset.
Warning
Do not exceed the recommended daily dose of 200mcg without medical supervision, as selenium can be toxic at high doses. Discontinue use and consult a healthcare professional if you experience metallic taste, garlic breath odor, brittle nails, hair loss, or unusual fatigue. Store in a cool, dry place away from children. Not intended to diagnose, treat, cure, or prevent any disease.
Pregnancy and Breastfeeding
Pregnant and breastfeeding women should consult their healthcare provider before taking Mason Selenium 200mcg tablets. While selenium is essential during pregnancy and lactation for proper fetal development and infant health, dosage requirements may vary. The established Recommended Dietary Allowance (RDA) for pregnant women is 60mcg and for lactating women is 70mcg of selenium daily.

Precaution
Individuals with autoimmune thyroid conditions should use selenium supplements only under medical supervision. Those with a history of skin cancer should consult their healthcare provider before use.

Important Information
