Product analysis
Selenium 200 mcg offers an inexpensive way to support normal immune function when selenium intake is low.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality80
Selenium is supplied as L-selenomethionine, a readily usable form. The accompanying calcium source is identified, but its absorption quality is less clear.
Ingredient Transparency100
Both nutrient amounts and forms are stated. That makes the selenium and accompanying calcium straightforward to check and compare.
Value For Money80
Selenium compares very favorably on cost for the amount supplied. The value of the accompanying calcium remains uncertain.
Customer Satisfaction94
Customer feedback is strongly positive across several thousand reviews. The large review base makes the satisfaction pattern less dependent on a small group of opinions.
Product Focus81
The formula is closely focused on selenium nutrition and normal immune function. Extra selenium does not reliably add benefit when intake is already adequate.

Goals
Selenium contributes to nutrient availability when dietary intake is insufficient. Its antioxidant-enzyme role does not establish extra benefit for people already obtaining adequate selenium, as most U.S. adults do. Calcium is also present, but 37 mg per serving is a small contribution compared with ordinary adult daily intake references.

Effective doses
Selenium contributes to normal immune function and selenium-dependent defenses when intake is inadequate. Extra selenium does not reliably improve these functions once status is adequate. The declared amount meets the saved comparison, but its particular form does not establish greater immune benefits or routine protection against respiratory infection.
