The Evidence for a Beneficial Role of Vitamin A in Multiple Sclerosis
https://link.springer.com/article/10.10 ... 014-0148-4
Vitamin A is an essential nutrient with important roles in immunological responses and in brain development. Its main metabolite is retinoic acid (RA), which is responsible for the neuroimmunological functions related to vitamin A. In the brain, RA is known to have interactions with other nuclear receptor-mediated signalling pathways. RA is involved in plasticity, regeneration, cognition and behaviour. In the peripheral blood, RA plays a major role both in increasing tolerance and in decreasing inflammation, through balancing T-lymphocyte populations. It is likely that RA synthesis may be manipulated by complex cross-talk among cells during infection and inflammation. The role of vitamin A in multiple sclerosis (MS) could be dual: at the same time as it decreases inflammation and increases tolerance of autoimmunity, it may also help in brain protection. The present review discusses the beneficial effects that vitamin A might have for controlling MS, although it must be clearly stated that, at the present time, there is no clear indication for using vitamin A as a treatment for MS. However, the results from the present review should encourage clinical trials with vitamin supplementation as a potential treatment or as an add-on option. Vitamin A acts in synergy with vitamin D, and the immunological homeostasis ensured by these vitamins should not be unbalanced in favour of only one of them.
odd sx? no dx? check w/ dietitian
DRI=MINIMUM eg bit.ly/1vgQclQ
99% don't meet these. meds/lifestyle can affect levels
status can be low in ms & other cond'ns
'but my results are normal'. typical panels don't test all
deficits occur in 'normal' range
