Product analysis

81 out of 100

Methyl Folate 800 mcg offers focused folate support for normal metabolism and blood formation when intake is low. Its favorable value is tempered by incomplete detail about the balance of the declared forms.

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

Nutrient Quality76

The declared methylfolate forms support a favorable quality conclusion. Their unspecified proportions leave some uncertainty about the balance of the preparation.

Ingredient Transparency80

The folate amount and forms are clearly identified for comparison. Their proportions are not stated, leaving the blend’s balance unclear.

Value For Money85

Folate has a favorable serving-cost comparison for its declared forms. The unknown proportions limit how precisely that value can be judged.

Customer Satisfaction91

Customer feedback is very positive across thousands of ratings. The large amount of feedback gives a broad picture of satisfaction without proving a health benefit.

Product Focus75

A single nutrient keeps the formula focused on folate intake. Its role in normal cell division does not establish routine hair regrowth.

Folate · 800 mcg

The declared B vitamins contribute to nutrient availability for normal metabolism and blood formation. Higher amounts do not establish extra benefit once intake is adequate.

How this product is rated for Everyday Health

Ingredient fit97

The known ingredients have a focused relationship to the retained nutritional functions. Amounts meet the comparison references.
Goal fit
The retained ingredients closely match the comparison focus; this describes nutritional relevance rather than comprehensive health improvement.
Dose adequacy
The retained amounts meet the saved comparison references; higher amounts do not establish extra benefit above nutritional adequacy.

Pathways60

The strongest retained connection is one-carbon metabolism and blood formation. Coverage of other functions is narrower.
Depth
The strongest retained connection is one-carbon metabolism and blood formation, based on the known ingredient amounts.
Breadth
The contribution is concentrated in one-carbon metabolism and blood formation, with limited coverage of other retained functions.

Evidence82

Vitamin B9 (Folate) provides the strongest retained evidence. The supplied context supports nutritional availability or limited population-specific findings, without establishing broad health improvements beyond adequate intake.
Evidence strength
Vitamin B9 (Folate) supplies the strongest retained evidence. Its supplied context limits expectations to nutritional or population-specific outcomes.
Studied preparation
The retained preparations match the saved criteria; no superiority of chemical form or delivery is established.

Formulation logic100

The supplied checks identify no configured conflict or missing required partner. The retained amount thresholds remain comparison references rather than treatment doses.
Partner coverage
The retained ingredients have no missing required partner under the saved criteria; this does not establish an added combination benefit.
Conflicts
No configured ingredient conflict was identified from the supplied amounts.
Effective doses
The retained amounts meet the saved minimum comparison threshold, which is not proof of a clinical effective dose.

Folate supports normal cell division and nutrient adequacy. This methylfolate serving reaches the saved amount reference, but the supplied information does not establish an independent hair-outcome dose or routine regrowth benefit. The form does not by itself demonstrate better hair results.

How this product is rated for Hair Health

Ingredient fit97

Vitamin B9 (Folate) are the main counted contributors. Amount recognition describes the saved comparison rather than a proven hair-treatment regimen.
Goal fit
Vitamin B9 (Folate) provide the formula's main connection to hair health.
Dose adequacy
The counted ingredients reach their saved amount references; this does not establish a proven hair-growth dose.

Pathways0

The findings identify a nutritional contribution without meaningful coverage of the named hair mechanisms.
Depth
The findings identify a nutritional contribution without meaningful coverage of the named hair mechanisms.
Breadth
No named hair mechanism reaches the saved coverage criterion.

Evidence68

Vitamin B9 (Folate) leads the counted support. Ingredient biology and preparation matching do not establish routine regrowth beyond the supplied limitations.
Evidence strength
Vitamin B9 (Folate) supplies the strongest counted support, but the supplied context limits expectations for routine hair growth.
Studied preparation
The counted forms meet the saved preparation match; this does not establish a hair benefit beyond the supplied ingredient limitations.

Formulation logic100

The counted ingredients have no unmet partner requirement or configured conflict. Small or unresolved ingredients remain subject to the saved amount findings.
Partner coverage
The counted ingredients have no unmet partner requirement in the supplied findings; this does not establish an added benefit from combining them.
Conflicts
No configured ingredient conflict was identified in the supplied findings.
Effective doses
All counted contributors meet the saved minimum amount criterion; that criterion is not proof of clinical effectiveness.
