Product analysis

93 out of 100

Selenium 200 mcg may help fill low selenium intake and support normal immune and antioxidant functions. Its clearly labelled, single-ingredient formula also offers very good value.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality90

Selenium is provided in a clearly identified yeast form. The form choice is favorable, although an extra benefit from the yeast itself is not established.

Ingredient Transparency100

The selenium amount and yeast form are both stated. That makes the contents easy to check and compare.

Value For Money100

The selenium content compares very favorably with the serving cost. Value is a clear strength for someone seeking selenium alone.

Customer Satisfaction91

Customer feedback is very positive across many thousands of reviews. The large review base gives a broad view of satisfaction, without proving health benefits.

Product Focus84

The single-ingredient formula is focused on selenium nutrition and normal immune and antioxidant functions. Benefits are most relevant when selenium intake is low, since extra intake does not reliably add benefit when needs are met.

Selenium · 200 mcg

Selenium can contribute to general nutrition when dietary intake is low. Its contribution sits in the antioxidant and immune category, but enzyme roles do not establish added protection or disease prevention in selenium-replete adults. The 200 mcg serving reaches full saved amount coverage. The yeast form receives no assumed advantage, and higher intake does not imply greater benefit.

How this product is rated for Everyday Health

Ingredient fit97

Selenium is the sole counted ingredient with full amount coverage.
Goal fit
Selenium gives the formula a concentrated nutritional purpose, with a small reduction for links to other goals.
Dose adequacy
The serving reaches full amount coverage without establishing additional benefit above adequate intake.

Pathways60

Selenium contributes in the antioxidant and immune category.
Depth
Antioxidant and immune defence reaches full coverage through selenium.
Breadth
Only antioxidant and immune defence reaches the coverage threshold.

Evidence82

Selenium supplies the evidence contribution for conditional nutritional usefulness.
Evidence strength
Selenium leads the evidence finding without establishing added benefit in selenium-replete adults.
Studied preparation
The selenium declaration receives full preparation recognition without a yeast-form advantage.

Formulation logic100

Selenium satisfies partner requirements and no configured conflict was found.
Partner coverage
Selenium lacks no required partner.
Conflicts
No configured ingredient conflict was matched.
Effective doses

Selenium · 200 mcg

Selenium provides a nutrient used in normal immune and antioxidant functions and can help when intake is low. The 200 mcg selected serving reaches the saved amount comparison. Selenium supplementation does not reliably enhance selenium-dependent functions when status is already adequate, and the supplied facts do not establish respiratory-infection prevention or superiority of the yeast preparation.

How this product is rated for Immunity

Ingredient fit97

The relevant ingredient selection fits the immune goal, although the product is also associated with other uses.
Goal fit
The relevant ingredient selection fits the immune goal, although the product is also associated with other uses.
Dose adequacy
The counted amounts reach the saved comparison endpoints, without establishing added benefit from higher exposure.

Pathways53

The strongest represented area is oxidative and inflammatory balance. The saved findings are concentrated in one immune function, giving limited breadth.
Depth
The strongest represented area is oxidative and inflammatory balance.
Breadth
The saved findings are concentrated in one immune function, giving limited breadth.

Evidence85

Selenium leads the saved evidence finding, primarily reflecting nutritional roles rather than proven added infection prevention.
Evidence strength
Selenium leads the saved evidence finding, primarily reflecting nutritional roles rather than proven added infection prevention.
Studied preparation
The counted preparations match the saved preparation finding; this does not establish superior benefit from particular forms or delivery.

Formulation logic100

The counted ingredients have their relevant partners or contribute independently, and no listed formulation conflict was triggered.
Partner coverage
The counted ingredients can contribute independently or have their relevant partners; an extra combined benefit is not established.
Conflicts
No listed formulation conflict was triggered; this does not establish safety of the whole product.
Effective doses
The counted ingredients reach the saved minimum amount comparison, which is not a proven clinical benefit threshold.
