AI assessment of the formula, label and price. How scoring works
Nutrient Quality20
Most ingredient forms are unclear, leaving absorption quality uncertain across the blend. Niacinamide ascorbate can be identified elsewhere on the label, but that does not settle the other forms.
Ingredient Transparency63
All ingredient amounts are stated, allowing serving comparisons. The main ingredient declarations omit forms, though niacinamide ascorbate is identifiable elsewhere on the label.
Value For Money40
The cost for vitamin C is moderate, while niacin is costly for what it supplies. Value remains uncertain for most of the additional ingredients.
Customer Satisfaction71
Customer ratings are generally positive. Feedback from 109 ratings gives a moderate picture of satisfaction.
Product Focus66
Vitamin C supplies the clearest support for normal immune and skin functions. The added ingredients do not establish routine cosmetic or inflammation benefits in adequately nourished adults.
