Product analysis

76 out of 100

Trace Minerals may help fill dietary gaps in minerals involved in normal immune function and antioxidant defenses. Its clearly listed amounts and forms make comparison straightforward.

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

Nutrient Quality70

Selenium, manganese and chromium use favorable forms for ingredient quality. Zinc and boron are named clearly, but their relative quality remains uncertain.

Ingredient Transparency100

Every mineral has a disclosed amount and form. That clarity makes it easier to compare the formula with your needs and other supplements.

Value For Money40

Value varies between minerals, with a favorable serving cost for manganese. Selenium and chromium compare less favorably, while zinc and boron cannot be judged confidently.

Customer Satisfaction95

Customers give consistently very positive ratings. A substantial number of ratings gives a broad view of customer satisfaction.

Product Focus81

The formula focuses on everyday mineral intake and normal immune function. Zinc and selenium matter most when they fill a dietary gap, rather than adding clear benefits to an already adequate intake.

Boron · 700 mcgSelenium · 100 mcgZinc · 15 mg

Zinc supports normal immune functions, while selenium contributes to antioxidant enzymes. They can help fill dietary gaps, without establishing enhanced immunity or disease prevention when intake is already adequate. The declared amounts receive substantial recognition, with selenium meeting the full comparison and zinc receiving partial recognition. Boron is excluded for its small amount, and its routine broad-health benefit remains unestablished.

How this product is rated for Everyday Health

Ingredient fit88

Zinc and selenium are recognized, with no off-goal active and few linked purposes.
Goal fit
Zinc and selenium are recognized, with no off-goal active and few linked purposes.
Dose adequacy
The two recognized amounts provide substantial but incomplete overall exposure coverage.

Pathways60

Antioxidant and immune functions are the sole represented pathway.
Depth
Antioxidant and immune functions receive the strongest coverage.
Breadth
Only antioxidant and immune functions meet the coverage threshold.

Evidence82

Selenium leads the saved evidence comparison; its contribution concerns nutrient availability when intake is low.
Evidence strength
Selenium supplies the strongest saved evidence contribution, without establishing added benefit above nutritional adequacy.
Studied preparation
All 2 ingredients meeting the amount threshold pass the preparation comparison; named forms receive no superiority bonus.

Formulation logic100

Recognized ingredients have no missing required partner or listed conflict; their amount findings are described separately.
Partner coverage
No credited ingredient lacks a required partner.
Conflicts
No listed ingredient conflict was found.
Effective doses
All 2 included ingredients reach the minimum exposure threshold, which is not a proven clinical benefit threshold.

Zinc · 15 mgSelenium · 100 mcg

Zinc contributes to normal immune-cell function, while selenium supports selenium-dependent systems involved in oxidative balance. These contributions matter when dietary intake is low. The chelate and selenomethionine descriptions do not establish superior outcomes, and selenium supplementation does not reliably add benefit when status is already adequate. The selected serving remains separate from repeated daily directions.

How this product is rated for Immunity

Ingredient fit68

Zinc and selenium provide the relevant immune connection. The amount comparison concerns one selected serving.
Goal fit
The meaningful immune connection comes from zinc and selenium. Broader uses do not establish additional immune effects.
Dose adequacy
The amount makes a partial contribution under the supplied comparison, without showing that nutritional needs are unmet.

Pathways73

The strongest represented area is oxidative and inflammatory balance. Two immune areas have substantial representation.
Depth
The strongest contribution concerns oxidative and inflammatory balance.
Breadth
Two immune areas have substantial representation.

Evidence100

Zinc leads the saved evidence finding. The relevant evidence supports normal nutrient function when intake is low, without establishing routine infection prevention.
Evidence strength
The relevant evidence supports normal nutrient function when intake is low, without establishing routine infection prevention.
Studied preparation
The included preparations meet the supplied comparison, without establishing superiority of named forms or delivery methods.

Formulation logic100

No configured ingredient conflict was identified; this is not an overall safety judgment. The included ingredients meet the amount threshold and have no missing required partner.
Partner coverage
The included ingredients work independently or have their required partner; this does not demonstrate extra benefit from combining them.
Conflicts
No configured ingredient conflict was identified; this is not an overall safety judgment.
Effective doses
The included ingredients meet the supplied amount threshold; this does not prove clinical effectiveness.
