I have been buying this product for a long time. I have low heloglobin and ferritin. Domestic drugs responded negatively in the stomach: pain and nausea. This one fits perfectly! I compared it with the original (my sister brought the last package from London with iHerb delivery from the USA). Box and insert as original. Blister quality! With the original, I can’t break through the blister with my nails to get a pill. I use a knife or whatever comes across . This package has the same thing ! According to the barcode - the manufacturer of the USA. For comparison, I put the original blister next to it.
