I want to try this. How do I go about it? I have primary progressive MS... Thanks.
Start simple and work yourself up. First get a selenium supplement or buy yourself brazil nuts. Brazil nuts are high in selenium. If you are eating brazil nuts, just eat in moderate amounts morning and evening. Eat just as you do with any ordinary nuts. For selenium supplements, just take the recommended amount and work yourself up for larger/smaller dosages until you find the proper dosages that you feel is best for you.
There is some new information, which shows TMG (trimethylglycine) in helping normalize nerve disorders very helpful for MS. You should see improvements within 3 days. If not, try adding more to the dosage or switching to another supplements. However, the primary treatment for MS is very likely be selenium, TMG, and magnesium.
The key is find the proper dosage and frequency for each supplement. Once you improve, you can keep adding one by one each of the recommendation that I have made above. However, if nothing works for you, then just try this: take about 5 grams of brewer's yeast a day and eat brazil nuts every day. Therapeutic effect can be seen within 1 month. Seems to work every time (could be a statistical anomaly due to small sampling) but how well is something I cannot say. What I can say is that they are natural, and the least harmful. This is used as a last resort if all else fails.
