Doctors and Trainers are finding more and more of their athletes’ low energy levels potentially tied to low ferretin (low iron) status.  Multi-V is formulated with Ferrochel Iron ®, a highly bio-available source of iron which is non-toxic and does not affect the absorption of minerals like other iron sources do. In addition, this unique and very effective iron amino acid chelate has been shown to improve ferretin levels in hard training athletes, which is important because it improves the oxygen carrying capacity of blood. For best results, take MultiV with your pre-exercise meal on days you are training or racing.  On days you aren’t exercising, you should take MultiV with a meal. First Endurance recommends using MultiV year round to protect yourself from the stresses and demands of training and racing.
