The RDA (recommended daily allowance) is worthless. It has more to do with avoiding malnutrition than promoting good health. If you choose to allow Big Pharma and government institutions control how you think about vitamins, you are on your own. I will not argue against the false data promoted by government health organizations.

300% is pure poppy cock. You are struggling and choose to ignore the best treatments. There are no set standards for time off work. You need time off until you heal. You need B-12 and the others for weeks to let the slow healing take place. If you choose to let your anxieties limit your choices, you alone will suffer.

B-12 did not cause your dehydration. Enough said.

My best to you.
