My doctor in canada said my iron level was 6 and it should be in the 100s. am i unhealthy?

Not necessarily: You have provided very little information. Are you a woman who is still having period? If you are that is probably the cause of iron deficiency. In any case do take oral iron supplements. Take the pills with meals and if constipation is an issue, take fiber laxative like Metamucil. If you are a man, you need to be investigated for blood loss in intestine.
