Since I took high dosage of Vitamin D (about 10'000 i.U) a day i get really acidic muscles in my legs if I climb more than 10stairs. It got a bit better with high dosage of magnesium. I dont have problems to walk 1hours+ if its flat . Tested negativ for D-lactat and L-Lactat. At my opinion it must has something to do with the maximun power of the muscles, otherwise i couldnt walk longer than an hour. Which other supplements could help me? Which minerals are more used if I have high levels of Vitamin D? Maybe Calcium or Potassium? I almost got a Vitamin D toxification, and it feels no like my musclecells are damaged... I additionally take active b-complex, L carnitin, .. Anyone can help?
