Reason for recall

Dietary supplement involved degradation of an ingredient. Product is sub-potent for Vitamin B12 not meeting label claims.

Potency and specification recalls happen when a batch tests outside its approved limits for strength, purity or dissolution, which can mean the dose delivered is higher or lower than labelled.
