I could not agree with you more. I hid my name for fear of getting flamed on this, but will come clean now. The blockage of vit d receptors is a huge issue, that everyone should carefully examine. The easiest way to do this is to have someone who does kinesiology muscle testing test various aspects of the the vit d pathway... levels of 25d, levels of 1,25 D... degree of blockage of vit d receptors. until this is sorted out, supplementing with vit d will do more harm than good. there really is not a one size fits all approach to heal. what helps one can hurt another. we should not buy into a modified allopathic view which substitutes vitamins or supplements for drugs. for some of us, including me, vit d worked just like a drug in suppressing imflammation, but long term, I paid a price as it slowly weakened my immune system. this is a real issue, not something cooked up by mainstream medicine to discredit vit d. lets face it, mainstream medicine is now pushing vitamin d. that alone should be rining alarm bells.
