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.

Gut und günstig
Hochdosiertes B12. Die Doctor‘s Best Produkte sind alle zu empfehlen, aber hier passt das Preis-/Leistungsverhältnis wirklich am besten! Gegenüber anderen Produkten aus der Apotheke deutlich besser von der Dosierung her und wesentlich billiger vom Preis!
