These are nutritional functions of selenium. They should not be interpreted as claims that this supplement treats or prevents a disease.

Important High-Dose Selenium Safety
Each capsule provides 200mcg of selenium, which is substantially more than the amount adults need each day from all sources. Check multivitamins, mineral formulas and other supplements before combining them with this product. Do not take additional high-dose selenium unless a healthcare professional specifically recommends it.
Excess selenium over time can cause adverse effects such as hair or nail changes, a metallic or garlic-like taste or breath, nausea, diarrhoea, tiredness or neurological symptoms. Stop use and seek professional advice if you suspect excessive intake or develop unexpected symptoms.
Who Should Ask a Healthcare Professional Before Use?
- Anyone already taking a multivitamin or another selenium-containing supplement.
- Anyone with thyroid, kidney or liver disease or another long-term medical condition.
- Anyone taking regular prescription medicines.
- Anyone who is pregnant or breastfeeding.
- Anyone with a soy allergy should check the label carefully because the manufacturer identifies soy as an allergen.
What Selenium Does Not Treat or Prevent
