Hi Moreless, I have very little knowledge about this. I believe that calcium, sodium,potassium are alkaline minerals and that vitamin D would have to be acid and sunshine alkaline. Do you recommend eating high potassium foods and molasses when not getting any sun? I did the LL magnetic clay baths. Would that pull the acids out like the epsom salts since it is two-thirds calcium? I was able to cure my hypothyroidism with the clay baths and then I went hyper and had to eat cabbage to suppress the thyroid which I still do. This is why I eat non-iodized salt only and stay away from kelp which has a lot of iodine. You can read my story in the hypothyroidism forum or click on the link below. Thanks.
