Why is iron important for athletes?

Iron is an essential mineral that plays a crucial role in many bodily functions, including the production of red blood cells and the transportation of oxygen to muscles. For athletes, iron is especially important, as it helps to increase endurance, reduce fatigue, and improve overall athletic performance.

Low iron levels can result in a range of symptoms, including weakness, fatigue, and impaired cognitive function, all of which can impact athletic performance. Athletes are at an increased risk of iron deficiency due to the demands of intense training and exercise, and may require higher levels of iron to maintain optimal performance. By ensuring adequate iron intake through a healthy diet and supplementation, athletes can help improve their endurance, speed up recovery time, and maximize their athletic potential.

Iron is especially important for female athletes due to several factors such as menstruation, pregnancy, and lactation. Women have a higher risk of low iron than men because of these additional demands on their bodies. During menstruation, women lose iron through blood loss and may not consume enough iron in their diet to replenish what is lost. In addition, iron is necessary for the growth and development of a healthy foetus during pregnancy and for the production of breast milk during lactation. Therefore, it is important for female athletes to pay attention to their iron intake.

What is Active Iron and how is it different from other iron supplements on the market?

Active Iron is a clinically proven iron supplement. Active Iron’s advanced protein formulation is clinically proven to give better absorption of iron sulfate and is gentle enough to take on an empty stomach. Unlike other iron supplements that can cause constipation, nausea, and other digestive problems, Active Iron uses a unique whey protein technology that allows the iron to be carried safely through the stomach to the small intestine where it is absorbed more efficiently. As a result, Active Iron is non-constipating and gentle on the stomach.

Active Iron is safe for use during pregnancy and breastfeeding. 

How long does it take for Active Iron to improve iron levels in athletes?

The length of time it takes for Active Iron to improve iron levels in athletes will vary depending on the individual’s iron status and the dosage used. Active Iron is clinially proven to increase iron levels by 94% in 6 weeks.  It is important for athletes to be patient and consistent with their supplementation, and to have their iron levels monitored regularly by their doctor or GP. 

Can athletes get enough iron from their diet alone, or is supplementation necessary?

While it is possible to get enough iron from a well-rounded diet, many athletes struggle to meet their iron needs through food alone. Athletes have higher iron requirements due to increased blood volume, muscle mass, and oxygen demands. Additionally, iron from plant-based sources (such as spinach and beans) is less readily absorbed by the body compared to iron from animal sources (such as red meat and poultry). As a result, many athletes choose to supplement with Active Iron to ensure they are getting the iron they need to support their athletic performance.

Is Active Iron suitable vegetarian athletes?

Yes, Active Iron is suitable for vegetarians. Many athletes following plant-based diets struggle to meet their iron needs through food alone, so supplementation with Active Iron can help ensure they are getting the iron they need to support their athletic performance.

How long should I take Active Iron?

The length of time you should take Active Iron will depend on your individual iron needs and levels. Stopping Active Iron supplementation prematurely may result in a return of  low symptoms. Your doctor or GP may reguarly montior your iron levels and adjust your diet and supplementation routine. Active Iron is suitable for long term use.
