I can only assume that Vitamin D and melatonin will fortify the system as it fortifies many systemic pathways but I have seen no evidence that they in and of themselves will cure MS. Do you have any such evidience?
I'm not convinced that MS is curable.
I think the remission that some CCSVI treatments have provided is probably temporary (though much to be welcomed by those fortunate few) as it's only addressing the symptom but not the cause of blocked veins. Stenting arteries is only a temporary measure for many, The approach Dr Davis uses at Track your Plaque is solving the problem that causes the blockages. Those with MS/AD caused by poor blood flow through brain (and consequent build up of iron) need to understand what is causing the poor blood flow (hence links to Uprightdoctor) and work on strategies to improve that scenario.
I think MS could be prevented and I think the progression of the condition may be slowed and I'm sure that most people with MS would have greater muscle strength, less chronic pain and better cognitive function when Vitamin D status is improved so that they have a stored reserve of D3.
Before I learn't about the late effects of polio I was attributing my symptoms to being potentially MS as many of the symptoms of MS apply equally to PPS, so I've been following the topic for many years. I don't think anyone who has had polio expects ever to be cured of the condition or cured of the late effects, I think the best we can hope for is to prevent further deterioration as best we can while doing our utmost to be as fit as our damaged bodies allow.
We know sufficient about the role of
vitamin D for chronic pain not to suffer unnecessary pain.
We can all improve our pain threshold, in the same way we can improve the ability of our skin to tolerate UV exposure.
