Product analysis

46 out of 100

Brewer's Yeast Powder Unflavored supplies B vitamins and minerals that can help fill dietary gaps. The precise nutrient forms are not disclosed, making closer quality comparisons difficult.

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

Nutrient Quality20

The nutrient forms are unspecified. That limits comparison of their individual preparation qualities.

Ingredient Transparency63

All listed nutrient amounts are disclosed. Their precise forms are missing, limiting closer comparison.

Value For Money39

The serving cost is favorable in the potassium comparison but high for phosphorus, and selenium is costly for its amount. Value for most other nutrients remains uncertain.

Customer Satisfaction79

Customer ratings are positive across a large review base. The feedback gives a broad picture of satisfaction, without establishing nutritional need or effectiveness.

Product Focus49

The main purpose is broad nutrient intake, especially when dietary intake is low. The many listed nutrients do not establish extra benefits when nutritional needs are already met.

A- Ingredient FitA+ PathwaysB+ EvidenceA+ Formulation Logic
Folate · 425 mcg DFEMagnesium · 30 mgSelenium · 65 mcgZinc · 2 mg

The B vitamins and folate provide nutritional availability when intake is low. Iron can help fill a dietary gap that would otherwise contribute to anaemia and fatigue. Other declared nutrients broaden nutritional availability, while larger amounts and special forms do not establish better outcomes above adequacy.

How this product is rated for Everyday Health

Ingredient fit86

Relevant declared nutrients contribute to nutritional support. Some small nutrient amounts are present but not counted, which limits the formula's contribution.
Goal fit
The relevant declared nutrients connect with general-health nutrition; additional purposes and ingredients limit how exclusively the formula addresses this goal.
Dose adequacy
Declared nutrient amounts make varying contributions; higher amounts in the saved comparison do not establish extra benefit above adequacy.

Pathways100

The strongest association is with energy metabolism cofactors. Contributions extend across several functional areas.
Depth
The strongest connection is energy metabolism cofactors, reflecting ingredient associations rather than demonstrated changes in health outcomes.
Breadth
Several nutrient-related functional areas meet the saved coverage threshold.

Evidence82

Vitamin B9 (Folate) leads the counted contribution. The evidence supports nutritional availability without establishing improved outcomes beyond adequate intake.
Evidence strength
Vitamin B9 (Folate) provides the strongest counted contribution, with practical relevance limited to nutritional availability when intake is low.
Studied preparation
The counted preparations are accepted in the nutrient comparison; chemical form and delivery do not establish additional health benefit.

Formulation logic100

No required partner or configured conflict was found. Counted ingredients meet the saved amount inclusion threshold.
Partner coverage
No required partner is missing for the counted ingredients; this does not establish an added benefit from combining them.
Conflicts
No configured formulation conflict was found at the supplied nutrient amounts and partner declarations.
Effective doses
All counted ingredients meet the saved amount inclusion threshold, which does not prove a supplement-response dose.

Magnesium · 30 mgVitamin B6 · 0.9 mgFolate · 425 mcg DFE

Potassium contributes to electrolyte balance and may support blood pressure, particularly when intake is low or blood pressure is elevated. Thiamin and selenium help fill nutritional gaps whose deficiencies can affect the heart, without established added cardiovascular benefit when intake is adequate. Folate contributes to homocysteine metabolism, but lowering this marker does not establish general heart protection. The small magnesium amount limits its contribution.

How this product is rated for Heart Health

Ingredient fit62

Vitamin B1 (Thiamin), Potassium, Magnesium provide the main relevant connections. Serving amounts and the breadth of the formula limit the connection to this goal.
Goal fit
Relevant ingredients sit within a broader formula, so only part of the ingredient mix connects to this goal.
Dose adequacy
The serving amounts provide partial exposure relative to the saved references, limiting how closely they resemble the compared exposures.

Pathways43

The strongest recorded connection is homocysteine metabolism. The formula has a narrow mechanism profile for this goal.
Depth
The strongest recorded connection is homocysteine metabolism; this describes a mechanism or marker rather than a proven clinical outcome.
Breadth
Meaningful recorded coverage is concentrated in homocysteine metabolism, leaving the broader goal only partly addressed.

Evidence89

Vitamin B9 (Folate) leads the recognized evidence. Homocysteine lowering does not establish broad cardiovascular benefit.
Evidence strength
Vitamin B9 (Folate) leads the recognized evidence. Its supplied limitations still apply; recognition does not establish cardiovascular-event prevention.
Studied preparation
The saved findings recognize the eligible preparations, without establishing that the finished product reproduces trial effects.

Formulation logic100

No required partner is missing and no configured conflict was found. Recognized ingredients meet the saved exposure threshold without establishing extra benefit from combining them.
Partner coverage
The recognized ingredients can contribute without an additional required partner; this does not establish synergy.
Conflicts
No configured ingredient conflict was identified in the supplied facts; this is a limited interaction check.
Effective doses
All ingredients included in this finding meet the saved minimum exposure threshold; that threshold is not proof of clinical effectiveness.

Magnesium · 30 mgZinc · 2 mgSelenium · 65 mcg

Selenium at 65 mcg supports normal immune function and antioxidant processes. Folate and B6 may help fill nutritional gaps needed for immune-cell function; the smaller zinc, iron, copper and magnesium amounts contribute less in the saved assessment.

How this product is rated for Immunity

Ingredient fit57

Selenium, folate and B6 provide the main immune relevance within a broader nutrient source. The three counted nutrients provide mixed, partial exposures overall.
Goal fit
Selenium, folate and B6 provide the main immune relevance within a broader nutrient source.
Dose adequacy
The three counted nutrients provide mixed, partial exposures overall.

Pathways20

Antioxidant and inflammatory balance is the strongest assessed route, with a smaller immune-regulation contribution. None of the assessed immune routes reaches the saved coverage level.
Depth
Antioxidant and inflammatory balance is the strongest assessed route, with a smaller immune-regulation contribution.
Breadth
None of the assessed immune routes reaches the saved coverage level.

Evidence85

Selenium provides the strongest saved evidence contribution at a counted amount; its evidence scope does not imply broad infection prevention. The counted ingredients match the preparation categories accepted in the saved findings.
