Product analysis
The Original Glacial Grape supplies vitamin B6 and potassium that may help when low intake contributes to tiredness or weakness. Undisclosed blend contents and missing preparation details make the complete formula harder to judge.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality23
Vitamin B6 has a named form, but most other ingredient preparations are not clearly disclosed. The unspecified blend and unclear potassium mixture leave important parts of the formula uncertain.
Ingredient Transparency44
Most active amounts are listed, but the carbohydrate amount is missing. Most preparations and the blend contents are also undisclosed, limiting a complete comparison.
Value For Money66
Sodium, potassium and leucine compare favorably on cost, while isoleucine offers favorable value. Glutamine and valine are less economical, and value for several other ingredients remains uncertain.
Customer Satisfaction86
Customer ratings are generally positive across thousands of reviews. The broad feedback supports a useful satisfaction picture without proving energy or exercise benefits.
Product Focus35
The clearest supported role is meeting nutrient needs when low intake contributes to fatigue or weakness. The amino acids do not establish independent fatigue relief, and the undisclosed blend leaves the full formula uncertain.

High effect
Potassium · 190 mg
Vitamin B6 supports normal energy metabolism and can help with tiredness when intake is low. Potassium helps prevent weakness associated with deficiency, without an established general energy boost. The amino acids isoleucine and valine have no established independent fatigue benefit. The 1000 mg of citrulline malate per serving is below the amounts used in the supplied exercise studies, whose results were mixed.
How this product is rated for Energy
Ingredient fit81
Vitamin B6, potassium, isoleucine and valine received consideration; the citrulline amount was too small to count.
Goal fit
Vitamin B6, potassium, isoleucine and valine received consideration; the citrulline amount was too small to count.
Dose adequacy
The included amounts contribute unevenly, with a smaller B6 contribution.
Pathways8
Muscle energy buffering has limited coverage from isoleucine and valine; this does not establish an independent fatigue benefit.
Depth
The strongest covered route is muscle energy buffering.
Breadth
No evaluated route reaches the required coverage level.
Evidence60
Potassium leads the saved evidence finding, while isoleucine and valine lack a matching studied preparation.
Evidence strength
Potassium leads the saved evidence finding, subject to the specific limitations described above.
Studied preparation
Potassium leads the saved evidence finding, while isoleucine and valine lack a matching studied preparation.
Formulation logic100
The included ingredients do not require an unmet partner, and no configured conflict was detected.
Partner coverage
No required partner is missing for the included ingredients.
Conflicts
No configured ingredient conflict was detected.
Effective doses
All 4 included ingredients meet the saved minimum amount threshold; that threshold does not prove fatigue relief.
