Product Overview

Iron is an essential mineral that plays a critical role in oxygen transport, energy metabolism, and overall vitality. The 21st Century Slow-Release Iron Supplement delivers 325 mg of ferrous sulfate per tablet, providing 65 mg of elemental iron in a specially formulated slow-release matrix. This design helps reduce the gastrointestinal discomfort often associated with high-dose iron supplements, making it a gentle yet effective choice for daily use. Each bottle contains 120 tablets, offering a convenient four-month supply at the recommended dosage.

Key Features and Benefits

  • High Potency Iron: Each tablet supplies 65 mg of elemental iron from ferrous sulfate, one of the most bioavailable forms of iron.
  • Slow-Release Technology: The controlled-release formulation allows iron to be released gradually, which can help minimize nausea, constipation, and other common side effects.
  • Vegan and Gluten Free: Suitable for plant-based diets and those with gluten sensitivities. No animal-derived ingredients or gluten-containing grains.
  • No Artificial Flavors or Added Yeast: Free from unnecessary additives, ensuring a clean supplement profile.
  • Easy to Swallow: The compact tablet size is designed for comfortable daily ingestion.

How to Use

Adults should take one tablet daily, preferably with a meal and a full glass of water. For best absorption, avoid consuming iron with coffee, tea, or calcium-rich foods, as these can inhibit absorption. If you miss a dose, take it as soon as you remember unless it is almost time for your next dose—in that case, skip the missed dose. Do not double the dose to catch up. Always follow the dosage instructions on the label or as recommended by a healthcare professional.

Who It Is For

This supplement is designed for adults who need additional iron due to dietary restrictions, increased needs (e.g., during menstruation, pregnancy, or intense physical activity), or conditions that affect iron absorption. It is particularly beneficial for vegetarians, vegans, and individuals with gluten intolerance. However, it is not intended for children unless directed by a physician. Consult your healthcare provider before use if you have a medical condition or are taking other medications.

Why Choose This Product

21st Century is a trusted brand committed to quality and affordability. This slow-release iron supplement offers a practical solution for those who require high-potency iron without the harsh side effects. The vegan and gluten-free formulation ensures broad compatibility, and the absence of artificial additives aligns with clean-label preferences. With 120 tablets per bottle, it provides excellent value for long-term use.
