Overview

["Slow Fe is a 45mg iron tablet built around slow-release technology, which the maker markets as easier on digestion than standard, immediate-release iron tablets. It's positioned for iron deficiency support and described as high potency with easy-to-swallow tablets.", "The bottle contains 60 tablets, and the label lists the product as vegetarian and unflavored. Slow-release iron formulas are designed to release the mineral gradually as the tablet moves through the digestive tract, which is the basis for the maker's digestive comfort claims.", "This is the best-selling product in this group by volume, with a 4.7 star rating across nearly 10,000 reviews and about 10,000 units bought in the past month. That level of repeat purchase suggests many buyers return to it after trying it once. As with any iron supplement, it's a good idea to talk to a healthcare professional before starting, particularly around dosing and timing."]

Frequently asked questions

What does slow-release mean for an iron tablet?

Slow-release tablets are designed to release the iron gradually as they pass through the digestive system, rather than all at once. The maker markets this as a gentler experience compared to standard iron tablets.

How many tablets are in a bottle?

This listing includes 60 tablets. Buyers who use it daily should plan on reordering roughly monthly depending on the recommended serving size on the label.

Can I take this if I've had stomach issues with iron before?

The slow-release format is marketed toward easier digestion, but individual tolerance varies. It's best to discuss your history with iron supplements with a healthcare professional before starting a new one.
