insights Analysis
21st Century Slow Release Iron offers 45mg of iron as dried ferrous sulfate, formulated for slow release to potentially minimize common gastrointestinal side effects. This dosage is adequate for addressing iron deficiency. However, a notable drawback is the inclusion of calcium carbonate, an ingredient known to inhibit iron absorption. For optimal effectiveness, this supplement would need to be taken separately from meals or other supplements containing calcium, which adds a layer of inconvenience and potential for reduced efficacy if not managed properly.
- Slow-release formulation may reduce gastrointestinal side effects
- Provides a substantial 45mg dose of iron
- Affordable price per serving
- Contains calcium, which can inhibit iron absorption if taken concurrently
- Requires careful timing of intake to avoid reduced efficacy
- Ferrous sulfate can still cause side effects for some individuals
- Take this supplement at least 2 hours apart from calcium-rich foods or supplements to maximize iron absorption.
- Consult a healthcare professional before use, especially if you have existing health conditions.

bolt Effectiveness for goals
Iron supplements are highly effective in treating iron deficiency anemia by replenishing the body's iron stores and increasing hemoglobin levels. Consistent use can help alleviate symptoms such as fatigue and weakness. Improvement is typically observed over several weeks to months.
For individuals with iron deficiency, particularly those with anemia, iron supplementation can significantly improve energy levels and reduce fatigue. This is because iron is crucial for oxygen transport throughout the body. If fatigue is not due to iron deficiency, supplements may not have this effect.
Iron supplements are generally very effective at increasing iron levels in individuals diagnosed with iron deficiency. They work by providing the body with the necessary iron to produce hemoglobin, a protein in red blood cells that carries oxygen. Consistent supplementation under professional guidance can help restore iron stores over time.
While some individuals may notice symptom improvement, like reduced fatigue, within a few weeks, it usually takes several months of consistent supplementation to fully restore iron stores. Hemoglobin levels often begin to rise within 2-3 weeks of starting treatment. Adherence to the prescribed regimen is key for full effectiveness.
For individuals experiencing fatigue due to iron deficiency anemia, iron supplementation can be effective in alleviating this symptom. As iron levels rise and red blood cell production improves, energy levels may increase. However, if fatigue is not caused by iron deficiency, supplements may not provide a benefit.
schedule Dosage, timing & forms
The recommended dietary allowance (RDA) for iron varies by age and gender. For adult men and postmenopausal women, it is typically 8 mg per day, while for premenopausal women, it is 18 mg per day due to menstrual blood loss. Pregnant women have an even higher RDA, often around 27 mg per day.
The Recommended Dietary Allowance (RDA) for elemental iron varies by age and sex. For adult men and postmenopausal women, the RDA is 8 mg per day, while for premenopausal women, it is 18 mg per day. These are general guidelines for dietary intake, and supplement dosages should consider individual needs and total daily intake.
Yes, there is a tolerable upper intake level (UL) for iron, which is 45 mg per day for adults from supplements and food combined. Exceeding this limit regularly can lead to gastrointestinal distress, and very high doses can be toxic, particularly in children. Iron overload can cause serious organ damage over time.
Yes, iron supplements can interact with various medications and other supplements. For example, iron can reduce the absorption of thyroid hormones, certain antibiotics (like tetracyclines and quinolones), and levodopa. It's advisable to take iron supplements at least 2 hours apart from these and to consult a healthcare professional.
Iron supplements are generally best absorbed when taken on an empty stomach, about one hour before or two hours after meals. However, taking it with food can help reduce gastrointestinal side effects like nausea or constipation. If taken with food, it's beneficial to include a source of vitamin C.
health_and_safety Safety & interactions
Yes, iron supplements can be highly dangerous and even fatal to young children if ingested in large quantities. Iron poisoning is a leading cause of accidental poisoning deaths in children under six. Iron supplements should always be stored out of reach of children in child-resistant containers.
Common side effects of iron supplements include constipation, nausea, stomach upset, and dark stools. Taking iron with food or adjusting the dose can sometimes help manage these symptoms. It's important to consult a healthcare provider if side effects are severe or persistent.
Common side effects of iron supplements include constipation, nausea, vomiting, stomach cramps, and dark-colored stools. Taking iron with food may help reduce gastrointestinal upset for some individuals. These effects are usually mild and may resolve as the body adjusts.
Yes, taking too much iron can be toxic, especially for children. Acute iron overdose can cause severe gastrointestinal issues, and chronic excess iron can lead to organ damage in conditions like hemochromatosis. It is important to only take iron under the guidance of a healthcare professional.
Yes, consuming excessive amounts of iron can be harmful and potentially toxic, especially in cases of acute overdose. Symptoms of iron toxicity can include severe stomach pain, vomiting, diarrhea, and in severe cases, organ damage. Individuals with certain genetic conditions like hemochromatosis are at higher risk for iron overload.

Iron 65.0
It's a reasonably dosed iron supplement, and the slow-release mechanism is a positive feature for stomach comfort. However, the presence of calcium is a significant formulation flaw that reduces its effectiveness as a sole iron source compared to products without absorption inhibitors.
Goals
Energy 68.0
The 45mg iron dose is effective for improving energy levels, and the slow-release may enhance tolerability. However, the presence of calcium could reduce the amount of absorbed iron, potentially slowing energy improvement.
Productivity Boost 68.0
While a good iron dose can enhance cognitive function, the co-presence of calcium may hinder optimal absorption, meaning the full productivity boosting potential might not be realized without careful dosing practices.
Hair Health 68.0
Iron is important for hair health. The iron content is beneficial, but the calcium could interfere with consistent iron delivery to the body, potentially limiting its full impact on hair.
