86.2 / 100Excellent

This provides a substantial thiamine dose in a gummy, but the label gives no age-specific directions and the magnesium amount is modest.

Scoring criteria

Quantity
100 / 100
The assumed serving provides 500 mg thiamine, a sufficient supplemental amount for the stated general support role; additional dose is not needed for this mark.
Form
75 / 100
Thiamine mononitrate is a conventional form without an established relevant absorption or tolerability advantage over ordinary alternatives.
Convenience
85 / 100
Directions are absent, so this assessment assumes one labelled serving of two gummies once daily.
Label accuracy
100 / 100
The stated 500 mg thiamine and 20 mg magnesium per two-gummy serving are internally consistent, with no established label contradiction.
Purity
75 / 100
No product-specific purity testing or other quality evidence is supplied, so ordinary quality remains unresolved.
Cofactors
0 / 100
The 20 mg magnesium is a modest amount and does not establish a meaningful complementary-dose benefit.
