Analysis

This product delivers 65mg of elemental iron from ferrous sulfate. It is designed for those who need a high-potency supplement to help with significant fatigue or hair density issues. It also includes a small amount of calcium to help stabilize the tablet.

Pros

  • Strong 65mg elemental dose
  • Extremely affordable price
  • Standard size tablets
  • Good 120-day supply

Cons

  • Sulfate form is prone to causing upset
  • Calcium might interfere slightly with uptake
  • Lacks Vitamin C

Warnings

  • Best taken with a meal to avoid nausea
  • Monitor for any digestive changes

Nutrient quality

76 High impact

A high 65mg dose is effective for therapeutic repletion but uses a less bioavailable and harsher sulfate form. The inclusion of Calcium (75mg) is a drawback as it can compete with iron for absorption.

Ingredient transparency

99 Highest impact

Labeling clearly identifies the elemental amounts of both iron and calcium utilized in the tablet. Directions for use and the full list of excipients are disclosed according to standard practices.

Customer satisfaction

89 Highest impact

Broad user feedback and high average ratings confirm the efficacy of the product for raising iron levels. However, a predictable number of users report gastrointestinal side effects consistent with the sulfate form.

Value for money

97 Highest impact

This is one of the most budget-friendly ways to access a high therapeutic dose of iron. The value is exceptional for users who can tolerate the basic sulfate form without major side effects.

Dried ferrous sulfate provides a high-potency dose of iron to support red blood cell function and oxygen delivery. Iron is mandatory for physical endurance and may contribute significantly to reducing systemic fatigue when levels are low.

A 65mg dose is a therapeutic level that appears well aligned with addressing clinical mineral deficiencies. While effective for raising iron status, the sulfate form is known for being less bioavailable and more likely to cause digestive discomfort.
