Selenium
What Is Selenium?
Selenium is an essential trace mineral your body needs in small amounts for antioxidant defence, thyroid function and immunity. It powers a family of protective enzymes (including glutathione peroxidase). WellBeingMora uses selenomethionine, a well-absorbed, food-form of selenium. A little is essential — but selenium has a narrow safe range, so balance matters.
Where Does Selenium Come From?
| Type | Essential trace mineral; provided here as selenomethionine |
| Food sources | Brazil nuts, seeds, whole grains, legumes (varies with soil) |
| Key roles | Antioxidant enzymes, thyroid hormone, immunity |
| Known for | Thyroid and antioxidant support |

Selenium Benefits: What Is Selenium Good For?
| Benefit | What the human evidence shows |
|---|---|
| Supports thyroid health | Selenium reduced thyroid antibodies in people with Hashimoto's thyroiditis in a meta-analysis. Toulis K et al., Thyroid, 2010 — meta-analysis. |
| Antioxidant defence | Selenium is essential for glutathione peroxidase, one of the body's core antioxidant enzymes protecting cells from damage. Well-established nutrition science. |
| Supports immunity | Adequate selenium supports normal immune function; deficiency weakens it. |
Important safety note: selenium has a narrow safe range. Enough is protective, but too much causes “selenosis” (hair loss, brittle nails, nerve issues). In a large trial, extra selenium did not prevent cancer and raised prostate-cancer risk in men who already had high selenium levels (Kristal A et al., J Natl Cancer Inst, 2014). Do not mega-dose — note that just one or two Brazil nuts already meet the daily need.
How Does Selenium Work?
- Builds antioxidant enzymes. Selenium is part of glutathione peroxidase and other selenoproteins that neutralise free radicals.
- Activates thyroid hormone. It helps convert thyroid hormone into its active form and protects the thyroid gland.
Selenium Uses: Thyroid, Antioxidant & Immunity
| Concern | How selenium may help & how strong the evidence is |
|---|---|
| Thyroid (Hashimoto's antibodies) | May lower thyroid antibodies. Moderate evidence. |
| Antioxidant defence | Essential for antioxidant enzymes. Well-established. |
| High-dose / already-adequate | Avoid extra — narrow safe range; possible harm. |
Selenium Dosage: How Much & When
Dose. Needs are tiny (micrograms per day) and easily met — a couple of Brazil nuts is enough. Do not exceed the recommended amount. Follow your product label.
Timing. Take with a meal, any time of day.
Selenium Side Effects & Who Should Avoid It
- Narrow safe range. Too much selenium causes hair loss, brittle nails, a garlic breath odour and nerve issues (selenosis).
- Don't stack sources. If you already eat Brazil nuts or take a multivitamin with selenium, avoid adding more.
- A supplement, not a treatment. Selenium supports thyroid and antioxidant health but does not replace medical care. Thyroid conditions should be managed with your doctor.

Frequently Asked Questions
1. What is selenium and what is it used for?
Selenium is an essential trace mineral needed for antioxidant enzymes, thyroid function and immunity. It is best known for thyroid and antioxidant support.
2. Is selenium good for the thyroid?
Selenium reduced thyroid antibodies in people with Hashimoto's thyroiditis in a meta-analysis, and it helps activate thyroid hormone. Thyroid conditions should still be managed with your doctor.
3. What is selenomethionine?
Selenomethionine is the natural, food-form of selenium (selenium bound to the amino acid methionine), which is well absorbed and used by the body.
4. Can you take too much selenium?
Yes — selenium has a narrow safe range. Too much causes selenosis (hair loss, brittle nails, garlic breath, nerve issues), so do not mega-dose.
5. How much selenium do I need?
Only micrograms per day, easily met by diet — a couple of Brazil nuts already covers the daily need. Do not exceed the recommended amount.
6. Is selenium safe with a multivitamin?
Yes, at the sensible level in a balanced multivitamin. The caution is against stacking multiple selenium sources (nuts plus multivitamin plus a separate high-dose supplement).
7. Does selenium prevent cancer?
No — a large trial found extra selenium did not prevent cancer and raised prostate-cancer risk in men who already had high selenium. It should not be taken for cancer prevention.
8. When should I take selenium?
With a meal, at any time of day.
9. Is selenium good for immunity?
Adequate selenium supports normal immune function, and deficiency weakens immunity. The goal is sufficiency, not excess.
10. Is WellBeingMora selenium vegetarian and allergen-free?
Yes. It is suitable for vegetarians and formulated without yeast, milk, lactose, soy, wheat, eggs, peanuts, shellfish, dairy, artificial flavours, or artificial sweeteners.
Final Thoughts
Selenium, as food-form selenomethionine, supports thyroid function, antioxidant defence and immunity. We flag the key safety point clearly: selenium has a narrow safe range, a little is essential and protective, but too much can harm — so it is best taken at sensible daily levels, not mega-dosed.
It is provided at a balanced level in the Whole Food Multivitamin — FSSAI registered, made in a GMP & US FDA registered facility, tested for purity, and free from common allergens. It is a wellness supplement, not a treatment.
