The product is genuine (which was my main concern ) , i have b12 deficiency (its 160 pg/ml and it should be between 210 - 700 ) and this is mainly for people with vit b12 deficiency.
But have to wait minimum 1 or 2 months to see actual results.
And for those wondering this is not a magic pill - no supplements are effective until you maintain a healthy lifestyle with proper nutrition.

Great
