So what is the consensus on supplementing Calcium while using high dose Vitamin D3 at 10,000Iu, soon to reduce to 5000IU? I'm also taking Vitamin K2 along with magnesium. I'm afraid of disturbing my electrolytes. I have an electrolyte powder which includes some Calcium but afraid to cause more calcium to enter into bloodstream. I'm taking Vitamin D3 to thicken blood as I have profuse bleeding with watery blood. (I'm a female) It's helping a bit but I notice intermittent heaviness on my chest, where I need to breath deeply. Afraid it may have pushed calcium to my lungs but I'm hoping this is just a start up effect of initiating Vitamin D3. I was pounding Vitamin K1 to clot my blood and while there were clots, my blood was still a watery consistency. Clotting may not be my issue after all. I've been housebound for 5 years so vitamin D3 is a must, also I can't consume dairy due to lactose/casein intolerance. At the moment, this electrolyte powder would be the only calcium source I have in the house. Was hoping electrolytes or Calcium would help thicken my blood, in addition to the D3. I also have very thin bones due to malnutrition and dietary intolerances. This is all after SSRI/Benzo withdrawals and high dose birth control to initially control the profuse bleeding 5 years ago. After high dose birth control pills, my stools turned yellow so i know my bile is now not breaking down fat soluble vitamins. I haven't taken recent Vitamin D3 bloodwork due to not being able to leave the house but a doctor told me years ago I was deficient in Vitamin D by a 25(OH)D test but I became so sick following medication withdrawals, that everything would cause flareups in symptoms. Now I'm stable enough to try, despite the bleeding issue still present. Bleeding issue was brought on by oral supplementation of glutathione given by a naturopath. Thanks for reading!
