Ottimo prodotto della Doctor's best
Ottimo integratore di b12 (metilcobalamina). Avevo timore che non essendo sublinguale ci sarebbero potuti essere dei problemi con l'assorbimento, invece ha riportato i miei livelli di b12 da carenti a ottimi nel giro di un solo mese.

Buon integratore di vitamina B12
Mi sono trovato bene con quest'integratore. Direi che ha un buon assorbimento.
