Bests & Worsts Reviews from Amazon

My daughter has been taking this multivitamin for over a year now. This is my first time purchasing on amazon (I’ve been paying double in stores!), and was iffy about the reviews but went for it since I’m familiar with the product. Her hemoglobin/iron levels require a multivitamin with iron and there are not too many options out there. Polyvisol has crap ingredients, Zarbees doesn't. I am not sure that many reviewers have used this vitamin before and because of that maybe don’t know what is “normal?” There are a lot of comments on the odor...that is the ferrous gluconate (the source of iron!), and it darkens around the mouth of the bottle when it dries (some reviewers thought it was mold). There has been some residue on nearly every bottle I’ve purchased. Maybe they could improve the seal, but if the plastic safety seal is still in tact, the open box (I’m sure it’s not always handled with caution...shipping problems) and what’s under the seal don’t disturb me too much. It’s improved my daughters iron, she likes the taste (regardless of the smell), and takes it without hesitation.
