INDICATION

NB Selenium 200mcg Tab is a trace mineral supplement used to prevent and correct selenium deficiency. Selenium supplementation is indicated in patients with Keshan disease, Kashin-Beck disease, thyroid dysfunction, immune deficiency, and as antioxidant support in patients at risk of oxidative stress-related diseases. It is also used as adjunctive support in cancer prevention research protocols.

MECHANISM OF ACTION

Selenium is an essential trace element incorporated into over 25 selenoproteins, including glutathione peroxidases, thioredoxin reductases, and iodothyronine deiodinases. Glutathione peroxidases are key antioxidant enzymes that neutralize hydrogen peroxide and lipid peroxides, protecting cells from oxidative damage. Iodothyronine deiodinases convert thyroxine (T4) to the active thyroid hormone (T3), making selenium critical for normal thyroid function. Selenomethionine is the organic form with the highest bioavailability.

DOSAGE AND ADMINISTRATION

• Adults: 200mcg once daily with food

• Do not exceed recommended dose; selenium toxicity (selenosis) occurs at doses above 400mcg daily long-term

• Short courses or dietary assessment should guide supplementation duration

• Always follow the dosage recommended by your healthcare provider

SIDE EFFECTS

Common:

• Nausea or stomach upset at high doses

• Garlic-like breath odor (characteristic of excess selenium excretion)

• Hair loss (with chronic excess)

• Fatigue

Less common:

• Selenosis with chronic overdose: hair and nail brittleness, neurological symptoms, skin rash

• Peripheral neuropathy with very high doses

• Diarrhoea and vomiting at toxic doses

• Nail discoloration and loss

NOT RECOMMENDED IN

• Do not exceed 400mcg/day to avoid selenosis

• Use with caution in patients with renal impairment

• Avoid concurrent use with other selenium-containing supplements without medical guidance

• Consult a doctor before use in pregnancy; some supplementation is recommended but dose-sensitive

DRUG INTERACTIONS

Selenium may reduce the bioavailability of cisplatin used in chemotherapy; discuss timing with your oncologist. Vitamin C in high doses may reduce the absorption of certain inorganic selenium forms; Selenomethionine is less affected. Selenium and vitamin E have synergistic antioxidant effects. Selenium does not significantly interact with common medications via CYP450 pathways.

STORAGE INSTRUCTIONS

Store below 25°C in a cool, dry place away from direct light and moisture. Keep in original packaging. Keep out of reach of children.
