Caroline Tarnowski 5 min read. Are my iron levels affecting my performance? Athletes are at a greater risk of being iron deficient in comparison to the general population.

Why are athletes more likely to be iron deficient? Supplementation may be advised to prevent iron stores from declining any further towards Iron deficiency anaemia where performance can be seriously affected. What are the signs that you may be iron deficient?

as iron stores become severely depleted, there is evidence to show that this negatively impacts physical performance. How do you test for an iron deficiency?

To diagnose iron deficiency it is suggested as a minimum that serum ferritin, haemoglobin concentration and transferrin saturation need to be considered. What are the different levels of iron deficiency?
