I take Sandra Cabot's Health Formulation. This formulation costs $12 for a bottle of 90 tablets.

Each tablet has:
calcium citrate 1050 mg /providing elemental calcium 221.6mg
hydroxyapatite 240 mg /providing elemental calcium 60 mg
magnesium oxide 227 mg
Manganese chelate 10mg
zinc gluconate 6.7mg
vitamin K4 7.5 mg
copper gluconate 3.5 mg/providing elemental copper 490 mg
Boran(as Borax) 750 mg

The bottle recommends to take 1-4 tablets daily. I take 2 in morning and 2 at bedtime.

Also I take B-complex (homeopathic blend) which also has an additonal 60 mg of magnesium oxide.

No good?? Am I taking too much?

Also this may be a bit weird sounding,but I have wanted to ask for a while now. If people have twitching and muscle spasms like me, all over, legs,arms, trunk etc. Why don't we also have heart twitching or spasms. I mean not too long ago I had Gerd if you remember and I had terrible esophagal spasms. What stops the heart from also twitching also? Isn't the heart a muscle too?
