Re: How's your intake of macrominerals? (Mg, Ca, and Silica)
Well, the body prefers to store calcium in the form of calcium phosphate. The levels of calcium in the blood are regulated by the parathyroid glands (just behind the thyroid in the neck), which combines those two elements if the levels need to be lowered. That could be why you had issues with calcium supplements, if you didn't have enough phosphate around in your system at that time to handle the influx of calcium.
I haven't tried magnesium glycinate myself, but can definately relate to the low blood pressure side effects too! Is always a Q of suiting intake to meet one's needs.
You list B12, b1, b2, and b3 (niacin and riboflavin)- that mix is still missing b6 and folate (and b6 is a phosphate vitamin). :) B6 as pyroxidal-6-phosphate (active form of B6) gives vibrant dreams.
The electrolyte tablets sound interesting, probably a better-balanced mix?
Struggling with anxieties may indicate low phosphate and zinc levels. It's listed on several pyroluria sites, and there's some decent reading available on it. (

Good on ye with the diet! That's the same intake I find really helps bloodsugar levels. :)
