Four hours for the vitamin supplements. 1 hour or more preferably for food
including those with natural vitamin C but this shouldn't be enough to affect it
Some believe vitamin C in any form should be minimised so this is a guide to maximise the effectiveness of the Miracle-Mineral-Supplement
The more vitamin C you take the longer it will take to reduce in your blood so 1 gram or so of supplement needs to be taken about four hours away
I don't know about the baths ,
