Ferrous sulfate is an iron salt commonly used in supplements to address or prevent iron deficiency anemia. Iron is crucial for producing hemoglobin, the protein in red blood cells that transports oxygen throughout the body—making it vital for physical performance and recovery.
In the athletic context, maintaining adequate iron levels supports endurance, energy production, and proper muscle oxygenation. Athletes, especially women and endurance athletes, are at higher risk of iron deficiency due to losses through sweat and menstruation.
Ferrous sulfate is widely used in multivitamins, iron supplements, and performance-enhancing blends where oxygen transport and energy metabolism are a concern.
Synonyms:
Iron(II) sulfate, FeSO₄
Benefits:
- Supports red blood cell production
- Enhances oxygen delivery to muscles
- Reduces fatigue associated with iron deficiency
- Contributes to energy metabolism
Sources:
Synthesized industrially for supplements; not naturally found in foods in this form.
Observations:
Best absorbed on an empty stomach, but may cause gastrointestinal side effects such as nausea or constipation. Often paired with vitamin C to improve absorption. Overconsumption can lead to iron toxicity.
