I've been struggling with low iron on and off for the last year, mostly because the generic brand supplements I was taking were high dose, low absorption, and generally made me feel like garbage and gave me HUGE GI discomfort. these things seem to be low dose with high absorption, and I'm feeling much better within two weeks of taking them - I feel stronger, more energetic, and am handling cardio exercise like a champ. they're really easy to swallow, the flavour is the best you could ask for of an iron supplement, and really considering you'll only need 1 a day, they're quite affordable. can only recommend!
