Product score

83.5 / 100Very good

Category average: 77.8 / 100

This is a high-potency one-tablet B-complex and zinc supplement for general adult use, rather than a proven treatment for stress.

Scoring criteria

Quantity
100 / 100
One daily tablet supplies substantial amounts of the listed B vitamins, vitamin C, vitamin E, zinc, and copper for routine adult supplementation.
Form
65 / 100
Several vitamin and mineral forms are not identified beyond folic acid, so relevant form-specific absorption and tolerability properties remain unresolved.
Convenience
100 / 100
The label directs adults to take one tablet daily with a meal, and the container provides 66 servings.
Label accuracy
100 / 100
The Supplement Facts panel is matched to a high-confidence FDA label record without an established amount contradiction.
Formula balance
75 / 100
The formula provides broad vitamin and mineral coverage at the labelled routine, although its high zinc and niacin amounts are not specifically targeted to a demonstrated stress need.
Purity
75 / 100
The label lists ordinary excipients and provides no product-specific contamination or independent quality-control evidence.
Cofactors
50 / 100
The declared copper amount has an established complementary nutritional relationship with zinc, but added clinical benefit from this pairing is uncertain.
