Product analysis

45 out of 100

The Original Mango Madness provides amino acids alongside vitamin B6, which may help with tiredness when intake is low. The blend components and most ingredient forms are not specified, making the full formula harder to assess.

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

Nutrient Quality22

Preparation quality remains uncertain for most ingredients because their forms are not specified. The unidentified blend adds further uncertainty about what the mixture contributes.

Ingredient Transparency44

Most amounts are listed, but the carbohydrate amount is missing. Nearly all forms and the blend components are unspecified, limiting a detailed comparison with alternatives.

Value For Money57

The sodium, potassium and leucine offer favorable value at the serving price. Isoleucine offers moderate value, while glutamine and valine are less competitive and the remaining comparisons are uncertain.

Customer Satisfaction89

Customer ratings are positive across a very large number of reviews. That broad feedback supports confidence in general satisfaction without proving energy or immune benefits.

Product Focus35

The clearest nutritional contribution is vitamin B6 for normal metabolism when intake is low. The amino acids do not establish a general energy boost, and glutamine's immune findings come from specific exercise settings.

B+ Ingredient FitF PathwaysC EvidenceA+ Formulation Logic
Potassium · 170 mg

Vitamin B6 supports normal nutrient metabolism and can help with fatigue related to low intake. Potassium replacement can address weakness from deficiency, but this serving does not establish a general energy effect. The isoleucine and valine findings do not establish independent fatigue benefits. Citrulline malate at 1,000 mg per serving was too low for inclusion in the saved comparison, and exercise findings do not establish everyday vitality.

How this product is rated for Energy

Ingredient fit81

The relevant ingredients provide a mixed connection to energy. Their declared amounts mostly approach the saved amount references.
Goal fit
The saved energy fit is diluted by broader product aims or ingredients outside the credited energy roles.
Dose adequacy
Amounts approach the comparison references overall, with some partial contributions.

Pathways8

The strongest saved connection is muscle energy buffering. No pathway reached the breadth threshold.
Depth
The strongest saved connection is muscle energy buffering.
Breadth
None of the assessed pathways reaches the saved breadth threshold.

Evidence60

Potassium provides the leading evidence contribution in the saved findings. Some included ingredients lack a matching studied preparation, limiting transfer of those findings.
Evidence strength
Potassium supplies the leading evidence contribution; its specific population and outcome limitations still apply.
Studied preparation
The preparation check is partial; Isoleucine, Valine lack a matching studied preparation.

Formulation logic100

The included ingredients have no missing required partners, and no configured conflict was matched. Each included amount clears the saved minimum comparison threshold.
Partner coverage
No required partner is missing from the included contributions.
Conflicts
No configured ingredient conflict was matched; this is not a comprehensive safety assessment.
Effective doses
All included ingredients clear the saved minimum amount threshold; this is a comparison cutoff, not proof of effective fatigue treatment.

Immunity
Impact
Moderate effect
D+ Ingredient FitF PathwaysB+ EvidenceA+ Formulation Logic

Glutamine at 2.5 g has limited, context-specific immune evidence: a supplied endurance-exercise study used two timed drinks after exercise, so its findings do not directly transfer to ordinary daily use. B6 at 0.64 mg contributes toward normal immune-cell function, particularly where dietary intake is low.
