Doesn't seem to be consistent with a lot of the things I've read on the interwebs. For example, my test enth says for antineoplastic (which means to prevent tumors/cancer) take 200-400 mg every 2-4 weeks. For antianemic purposes, take 400 mg a day for a week. That sounds like a bit much. It also says it's hepatoxic, and may cause liver tumors.
