Questions We Actually Get
When should I take Selenium?
1 tablet a day, with a meal and water. Ideally in the morning, for steady support of your thyroid and energy.
Is it safe?
Yes, at the recommended dose. Don't exceed 1 tablet (100µg) a day — selenium is needed in small, precise amounts.
How fast will I see a result?
Many feel more energy within the first few weeks. For your thyroid, nails and hair, steady use over 6–8 weeks is ideal.
What's inside?
100µg of selenium per tablet, in an easily absorbed form. 90 tablets, no needless extras.
Is this a scam?
You pay, it arrives discreetly at your door — cash on delivery. You try it, and if it's not for you, you get your money back within 30 days.
Can I take it with other supplements or medication?
Selenium pairs well with vitamin E, zinc and vitamin D. If you take thyroid medication, or you're pregnant or breastfeeding, check with your doctor first.
How do I take it?
1 tablet a day, with a meal and plenty of water.
Who's it for?
For anyone who wants to support their thyroid, energy and immune system — especially if their diet doesn't cover their selenium needs.
How a slow metabolism quietly wears you down
It's not that you're doing something wrong — it's that the body runs low on a key trace element. And that can change.
Feeling worn out for no obvious reason? Your metabolism may need some support.
You wake up tired and never quite recover through the day. The body's asking for fuel.
Brittle nails and hair loss often point to a lack of key trace elements.
Getting sick easily? A weakened immune system needs a boost.

How Selenium works in your body
Selenium shields your cells.
Selenium is built into selenoproteins and glutathione peroxidase — the body's natural antioxidant defense that protects cells from free radicals.
Supports your thyroid.
Selenium takes part in the synthesis of the T3 and T4 hormones, which regulate metabolism, energy and body temperature.
More energy, naturally.
With your thyroid and metabolism working properly, you feel less fatigue and more energy through the day — while your immune system is supported too.
