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

Nutrient Quality50

Vitamin D3 and natural vitamin E are favorably characterized forms. The fish oil and vitamin A lack enough comparative detail for the same conclusion.

Ingredient Transparency65

Amounts are disclosed, and the vitamin sources are named. The relative contributions of the different vitamin A and D sources are not disclosed, limiting a closer comparison.

Value For Money68

The vitamin A and E contributions offer favorable value for the amounts supplied. Vitamin D offers less favorable value, while the fish oil contribution cannot be compared reliably on cost.

Customer Satisfaction81

Customer feedback is very positive across several hundred ratings. The ratings reflect satisfaction and do not establish effectiveness or safety.

Product Focus30

The formula covers a limited range of intended uses. Its fit with those uses remains uncertain despite the clear vitamin forms.
