I know those of us with chronic conditions or who are still seeking diagnosis do not want to spend still more money on medical visits or testing - especially if we have had unsatisfactory experiences or our finances are strained, or even if we’re just plain emotionally fatigued or angered by the lack of help - but I would hesitate before starting any diets, new supplements or increased vitamin doses based on something from a website, no matter how reputable, without first consulting a qualified medical professional that should consider any change in light of medical history and any medications you may be taking. Many forms of various vitamins, for example, exist with some barely bioavailable (in which case they are a total waste of money) to some being highly absorbable. Some forms may interact in dangerous ways with some medications, either enhancing or reducing their effectiveness. Some forms may be outright toxic for the individual with certain otherwise insignificant DNA variants that are not routinely tested for but are more common than one might think.
