Douglas Laboratories Timed Release Iron

Brand: Douglas Laboratories · Form: TABLET [E0155]

Our assessment

Our assessment: The evidence shows that Douglas Laboratories Timed Release Iron is a targeted supplement for individuals with confirmed iron deficiency. Data on this specific product is limited, but the active ingredient, iron, is essential for oxygen transport and energy metabolism. You should only use this supplement if a healthcare provider has identified a deficiency through blood tests, as excess iron can be harmful.

How it works

Iron is a critical component of hemoglobin, the protein in red blood cells that carries oxygen from your lungs to the rest of your body [NIH ODS]. It also supports muscle metabolism and connective tissue health. The "timed release" formulation in this product is designed to release iron gradually, which may help reduce gastrointestinal side effects compared to immediate-release forms.

Safety profile

The FDA has received a total of 592059 adverse event reports across all supplements, though specific reports for this product are not available [FDA data]. Side effects for iron supplements can include constipation, nausea, and stomach upset. Taking iron with food can help, but note that calcium can reduce iron absorption [NIH ODS]. High iron levels are toxic, so never exceed the recommended dose.

Our recommendation

Our recommendation: Only use this supplement if you have a confirmed iron deficiency, such as from heavy menstrual bleeding or a restricted diet. Start with one capsule daily and take it on an empty stomach with vitamin C (like orange juice) to enhance absorption. If you experience significant stomach discomfort, take it with a small amount of food. Data on long-term safety beyond standard iron guidelines is not available.
