Excessive coaching quantity will increase iron calls for. Add menstrual blood loss or a food plan low in heme iron (the kind present in animal merchandise), and even sturdy, constant runners can fall behind. There’s additionally a lesser-known issue: foot-strike hemolysis—the repeated impression of physique weight on the toes can break down pink blood cells, decreasing iron ranges over time. It’s a well-documented phenomenon amongst endurance runners and athletes in high-impact sports activities.
Jessica Brake discovered this the exhausting approach. A passionate marathoner, she had simply certified for the Boston Marathon with a private greatest of three:29. However afterward, her efficiency declined sharply. Regardless of coaching simply as exhausting, she completed her subsequent marathon practically an hour slower. Her power was gone, and her confidence together with it.

After researching choices and seeing a suggestion from elite runner and dietitian Rachel Hannah, she turned to Ferosom Iron.
Meals Isn’t At all times Sufficient

When bodily calls for are excessive, and menstruation or endometriosis is within the image, the physique’s iron wants usually outpace what food plan alone can provide.

For Brake, it labored. She skilled higher consistency and actual outcomes with out the negative effects. Inside months, her power rebounded. She wasn’t simply ending exercises; she was bettering once more.
Years after her irritating post-Boston stoop, she got here again stronger, clocking a brand new private greatest of three:29:40 on the Mississauga Marathon and ending because the twelfth general feminine.
It was the sturdy comeback she by no means anticipated.
