Overview
Carlyle's CL16384 packs 45 mg of slow release ferrous sulfate iron into 180 tablets, formulated as vegetarian, non-GMO and gluten free, and pitched as a men's and women's mineral supplement.
Slow release iron tablets are designed to release the mineral gradually rather than all at once, which is the usual reasoning behind that format for people who find regular iron supplements hard on the stomach. At 180 tablets, one a day covers roughly six months.
- 45 mg slow release ferrous sulfate
- 180 tablets per bottle
- Vegetarian, non-GMO, gluten free
- Carlyle model CL16384
Who it's for
Fits adults who need an iron supplement and have found standard immediate release iron tablets upsetting to their stomach. Not a substitute for medical treatment of diagnosed iron deficiency, where a doctor should set the dose.
Pros and cons
- 180 tablets is close to a six month supply at one a day
- Vegetarian and gluten free formula
- Slow release format aimed at easier tolerance
- Iron supplements can still cause stomach discomfort in some people regardless of release speed
- 45 mg is a specific dose that should match what's actually needed
- Tablet form, not a capsule or liquid
Performance notes
Ferrous sulfate is one of the more common iron forms in supplements, and the slow release coating is meant to spread absorption out over time instead of delivering it all at once. Individual tolerance for iron still varies.
